915 Generation 12V TEC112706 Semiconductor Refrigeration Thermoelectric

Detailed Information About The Product:

1. The substrate uses superconducting aluminum as the substrate, which breaks the conventional mode of using alumina ceramic substrates. It is helpful for welding during the installation process, so that it can be in close contact with the radiator and cooler at zero distance.
2. The device uses innovative zinc telluride as raw material, which perfectly reps the mainstream of bismuth telluride as raw material with its excellent material figure of merit. This innovation increases the overall temperature difference of the device by 3.5℃, and the cooling rate is higher than the original device. 10S shortened
3. The thickness of the device is 5.7mm, and the thickness of the ordinary device is usually between 3-4mm. The size of the PN junction unit of the device is changed from the original 1.4x1.4x1.5mm to 1.4x1.4x2mm, which helps to increase the cooling effect. The distance between the hot-terminal reduces the influence of the heat release of the hot end on the cooling of the cold side
4. The service life is over 40WH, and the device has undergone the following rigorous tests to make the storm more violent: Polarity switching test: This test mainly investigates the influence of thermal stress on the life of the refrigerator.
5. Test method: 20℃~80℃, 5 minutes of forward current and 5 minutes of reverse current is a cycle. High temperature storage test: This test mainly investigates the influence of the diffusion of harmful elements on the life of the refrigerator. Test method: The company now conducts two high-temperature storage tests at 90℃ and 150℃.

Low temperature storage test: This test mainly investigates the low temperature characteristics of various materials in the refrigerator.
Test method: The company is now conducting -40 ℃ low temperature storage test.
Temperature shock test: This test mainly investigates the influence of thermal stress on the life of the refrigerator.
Test method: 70℃ (30 min) / -55℃ (30 min), conversion time 1 min, 5 cycles
Impact test: This test mainly examines the ability of the refrigerator to withstand external impact.
