Visit the Store The side with words is close to the heat dissipation surface (cold end), and the side without words is close to the heat absorption surface (hot end). The red wire is connected to the positive pole and the black wire is connected to the negative pole. When there is a temperature difference, it can generate electricity (increase the voltage in series and increase the current in parallel). Correct Installation Method of Semiconductor Refrigeration Sheet: The heat sink shall be installed at the hot end of the refrigeration fin, and the cold guide system shall be installed at the cold end. The flatness of the installation surface shall not be greater than 0.03mm, and burrs and dirt shall be removed; The refrigeration fin shall be in good contact with the heat sink and the cold guide block, and the contact surface shall be provided with a thin layer of heat conducting silicone grease; When fixing the refrigeration sheet, we should not only make the refrigeration sheet evenly stressed, but also pay attention not to be excessive, so as to prevent the porcelain sheet from fracturing. Selection of Power Supply and Control Mode: When the refrigeration sheet works, it can be directly powered by DC power supply, whether it is battery or switching power supply, or simple rectifier DC power supply. Refrigeration chip is a low impedance semiconductor device, which is equivalent to loading a resistor on the power supply. Due to the intrinsic properties of bismuth telluride material, the resistance of the refrigeration sheet increases by about 0.5% every 1 ? increase in the average temperature. As long as the AC ripple coefficient of the traditional battery charger is not overloaded, it can provide enough power for the refrigeration sheet. In order to achieve simple temperature control, a standard thermostat or a variable output DC power supply can be used to adjust the input voltage of the refrigeration sheet. Under the application conditions of relatively stable thermal load, the use of manually regulated DC power supply can ensure that the temperature fluctuation does not exceed 1 ? within a few hours or more. If you need to accurately control the temperature, you generally need to use a closed-circuit (feedback) system to automatically control the input current through PID or PWM. At this time, the accuracy of temperature control can be kept within ± 0.1 ? or even higher. Compared with other typical electronic devices, whether to install the filter of power ripple coefficient is not very important for the refrigeration blade. However, we still suggest that the fluctuation range of ripple coefficient should be controlled within 10%, and it is better to keep it within (5%). HOW TO DISTINGUISH THE HOT AND COLD SURFACES OF THE REFRIGERATION SHEET: A Dry Battery Can Be Used to Test the Quality of the Refrigeration Sheet and the Cold and Hot Surfaces: With one hand, press the red line of the refrigeration sheet on the positive pole of the battery and the black line on the negative pole of the battery. With the other hand, touch both sides of the refrigeration sheet. If you feel that one side is slightly hot and the other side is slightly cold, it means that the refrigeration sheet is good. Distinguish the Cold and Hot Surfaces of the Refrigeration Sheet According to the Welding Position of the Lead: The red and black leads of the refrigeration sheet are usually welded on the hot surface of the refrigeration sheet. Therefore, when the red wire of the refrigeration sheet is connected to the positive electrode and the black wire is connected to the negative electrode, the side with the lead welded is the hot surface and the other side is the cold surface. Judge the Cold and Hot Surfaces of the Refrigeration Sheet According to the Printed Side: On the premise that the red wire of the refrigeration sheet is connected to the positive electrode and the black wire is connected to the negative electrode. The printed side of our refrigeration sheet is the cold side. When the red line of the refrigeration sheet is connected to the negative and the black line is connected to the positive, the printed side of our refrigeration sheet is the hot side. Note that only the single-layer refrigeration sheet can be connected with positive and negative poles, and the multi-layer refrigeration sheet must be connected with positive and negative in red and black. Maximum Temperature Difference Voltage: The ability of the refrigeration sheet to maintain the temperature difference at both ends is directly proportional to the DC voltage applied to the refrigeration sheet. The voltage when the maximum temperature difference is reached is called the maximum temperature difference voltage. When the applied voltage exceeds this voltage, the temperature difference will decrease. The maximum temperature difference voltage shall be used when measuring the maximum cooling capacity. The voltage when the device is used shall be less than this voltage. The most commonly selected range is 70% - 80% of the maximum voltage. When the required temperature difference is small, a smaller voltage can be used. At this time, the maximum temperature difference and maximum cooling capacity that can be obtained are also relatively small. Maximum Temperature Difference Current: It is an important index to determine the power of the refrigeration sheet, sometimes represented by resistance value. It is the current value under the maximum temperature difference voltage when the temperature of the cold and hot surface is 27 ? (the temperature difference is 0). The current of the refrigeration sheet is generally less than this value, and the actual working current will decrease with the increase of the temperature difference and the temperature of the hot surface. Advantages and Characteristics of Semiconductor Refrigeration Sheet: Without any refrigerant, it can work continuously without pollution source, rotating parts, rotary effect and sliding parts. It is a solid piece without vibration and noise during operation and easy to install. Semiconductor refrigeration chip has two functions: cooling and heating. The refrigeration efficiency is generally 55-60%, but the heating efficiency is very high, always greater than 1. Therefore, using one piece can replace the separate refrigeration system and heating system. Semiconductor refrigeration chip is a current energy exchange chip. Through the control of input current, high-precision temperature control can be realized. Combined with temperature detection and control means, it is easy to realize remote control, program control and computer control, so as to form an automatic control system. The thermal inertia of semiconductor refrigeration sheet is very small, and the cooling and heating time is very fast. Under the condition of good heat dissipation at the hot end and no-load at the cold end, the refrigeration sheet can reach the maximum temperature difference in less than one minute after power on. The reverse use of semiconductor refrigeration chips is thermoelectric power generation. Semiconductor refrigeration chips are generally suitable for power generation in medium and low temperature areas. The power of a single pair of refrigeration elements of a semiconductor refrigeration chip is very small, but if it is combined into an electric stack and combined into a refrigeration system by series and parallel connection of the same type of electric stack, the power can be very large. Therefore, the refrigeration power can range from a few milliwatts to tens of thousands of watts. The temperature resistance of the normal temperature hot surface of the semiconductor refrigeration sheet is 80 degrees, the temperature resistance of the medium temperature hot surface is 150 degrees, and the temperature resistance of the high temperature hot surface is 200 degrees; The temperature difference between the hot end and the cold end can reach 67 degrees in the first stage, 80 degrees in the second stage, 90 degrees in the third stage and 107 degrees in the fourth stage. Precautions for the Application of Refrigeration Tablets: The working state of the refrigeration blade is to cool and heat at the same time. When the refrigeration blade works, the hot surface must be well dissipated. It is strictly prohibited to energize the refrigeration blade for more than 3 seconds without heat dissipation, otherwise it will cause overheating and burning. The power on during the cold and heat exchange of the refrigeration sheet must wait until both sides of the cold and heat return to room temperature (generally 5 to 10 minutes), otherwise it is very easy to cause the circuit damage of the refrigeration sheet and the rupture of the ceramic panel When the refrigeration sheet is used for refrigeration, the red line is connected to the positive pole of the power supply and the black line is connected to the negative pole of the power supply. The power supply requires switching power supply with ripple coefficient less than 10%. If the positive and negative poles of a single-layer refrigeration sheet are switched, that is, the red wire is connected to the negative pole and the black wire is connected to the positive pole, the cold and hot surfaces of the refrigeration sheet are also switched. Note that the positive and negative poles of multi-layer refrigeration sheet cannot be adjusted. When the radiator is not installed on the hot surface of the refrigeration sheet, do not turn on the power supply; Poor heat dissipation on the hot surface of the refrigeration sheet will lead to excessive temperature, exceeding the maximum bearing temperature of the hot surface of the refrigeration sheet and overheating and burning. Because the refrigeration sheet uses the temperature difference between the cold and hot surfaces for refrigeration, the lower the temperature of the cold surface, the better the refrigeration effect. The refrigeration sheet is made of ceramic panels on both sides and bismuth telluride semiconductor materials in the middle by welding with low melting point solder. It is a fragile material with low strength. Please use it carefully to avoid damage caused by the fracture of ceramic panels or the fragmentation of bismuth telluride particles. Correct Use Conditions of Semiconductor Refrigeration Chip: The voltage of DC power supply shall not exceed the maximum limit voltage, and the ripple coefficient of power supply shall be less than 10%; The reverse voltage cannot be applied instantaneously when the refrigeration sheet is working (after 15 minutes); There is no water inside the refrigeration sheet; The humidity around the refrigeration sheet shall not exceed 80%; The ambient temperature of the refrigeration sheet shall not exceed 60 ?. Under the Following Conditions, the Service Life of Semiconductor Refrigeration Sheet Will Be Greatly Reduced or Even Damaged Rapidly: The hot surface of the refrigeration sheet does not contact any heat dissipation device; The pressure of the refrigeration sheet during assembly exceeds its maximum bearing pressure; Frequently switch between hot and cold; Use in case of vibration; The refrigeration sheet is used in the environment with high humidity, heavy dust and high temperature; The heating surface of the refrigeration blade has poor contact and poor heat dissipation. Selection Method: 1. In order to select the specification of the refrigeration sheet, it is necessary to determine the required refrigeration capacity, that is, the heat to be removed. If it cannot be measured accurately, it can also be calculated and estimated through external conditions such as temperature rise, and the estimated value is marked as QC. If the difference between the cold surface temperature and the ambient temperature is less than 30 ?, it belongs to conventional refrigeration applications, and 1.5 * QC is directly compared with the maximum refrigeration capacity of 27 ? in the specification table of the refrigeration sheet, Find the specifications with similar values (soil 5 \") and then refer to the current and voltage you want to use to select a suitable refrigeration sheet. 2. For the very cold application with refrigeration temperature of 30 ? - 60 ?, the specification of 2.5 * QC or even higher refrigeration capacity needs to be selected, because the characteristic of the refrigeration sheet decreases linearly with the increase of temperature difference. 3. The restriction of heat dissipation conditions shall also be fully considered when selecting the refrigeration sheet. The heat dissipation conditions directly affect the temperature of the hot surface of the refrigeration sheet. During the operation of the refrigeration sheet, the heat pumped out from the hot surface and the heat generated by the power consumed by the refrigeration sheet during operation need to be continuously removed. The value of the total heat dissipation is equal to QC + U * I, which is the power input to the device. If the heat dissipation is insufficient, the heat will flow back to the cold end, raising the temperature of the cold end, Therefore, when the heat dissipation conditions are restricted, it is possible to improve the refrigeration effect by selecting refrigeration fins with small power. 4. As a choice, a scheme is to replace a small number of high-power refrigeration fins with a large number of low-power refrigeration fins to obtain the same refrigeration capacity. The purpose is to increase the heat source area and reduce the heat dissipation power density. A few high-power refrigeration fins often need water cooling for heat dissipation. For example, 12715 refrigeration fins work at 12V. When the current is 9A, according to the characteristic diagram of Th = 50 ?, QC = 10W, and the heat dissipation capacity QH = 12 * 9 + 10 = 118W, so the heat dissipation load is very large, and the requirements for radiator are very high when air cooling heat dissipation. The solution can use two 12708 instead or adopt water cooling.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e✅ ?Sealing Structure,Safe to Use?:Single-layer double-sided ceramic structure,alloy semiconductor material inside,can directly convert thermal energy into electrical energy.\u003c\/li\u003e\n\u003cli\u003e✅ ?High Reliability and No Pollution?:Red wire to positive,black wire to the negative, it generate electricity when the temperature difference happened.\u003c\/li\u003e\n\u003cli\u003e✅ ?Connection Method?:In practical applications, in order to seek higer output voltage and load current, multi-parallel-parallel combination is adopted.\u003c\/li\u003e\n\u003cli\u003e✅ ?Color-Coded Leads For Identification?:Cable length is 14cm\/ 5.5\",red(+)and black(-),color-coded leads for identification of polarity.\u003c\/li\u003e\n\u003cli\u003e✅ ?Light Weight, Long Life?:Small size (40*40mm\/1.6\" )and light weight, convenient for use.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003e✅ Product Dimensions:\u003c\/strong\u003e 3.78 x 2.76 x 0.39 inches; 0.95 ounces\u003c\/p\u003e\n\u003ch3\u003eShipping \u0026amp; Guarantees\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e✅ FREE standard shipping within the United States (3–6 business days)\u003c\/li\u003e\n\u003cli\u003e✅ 100% money-back guarantee for lost or damaged items\u003c\/li\u003e\n\u003cli\u003e✅ Secure checkout with encrypted payment processing\u003c\/li\u003e\n\u003cli\u003e✅ Shipping via UPS, FedEx, and USPS\u003c\/li\u003e\n\u003cli\u003e✅ Ships to lower 48 states only (no PO Boxes \/ APO \/ FPO)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eReturns\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e✅ 30-day hassle-free returns\u003c\/li\u003e\n\u003cli\u003e✅ Items must be unused and in original packaging\u003c\/li\u003e\n\u003cli\u003e✅ Full refund if item is not delivered\u003c\/li\u003e\n\u003cli\u003e✅ Guaranteed delivery within 6–7 business days\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003ePayment Methods\u003c\/h3\u003e\n\u003cp\u003e✅ Credit Cards, PayPal, Shop Pay, Apple Pay, Google Pay, Amazon Pay, Meta Pay\u003c\/p\u003e\n\u003ch3\u003eCustomer Support\u003c\/h3\u003e\n\u003cp style=\"text-align:left;\"\u003e✅ Questions?
