Problems solved by technology

[0004] Although the electric card refrigeration device can obtain better cooling capacity, the current electric card refrigeration technology cannot transfer heat efficiently, and the heat absorbed by the electric card refrigeration device cannot be efficiently released to the external environment, resulting in the The continuous refrigeration capacity is very poor, which restricts its practical application

In order to solve this problem, there is currently a way to use a thermoelectric refrigeration device composed of semiconductor couples to transfer heat from the electric card refrigeration device. This is an ideal heat cycle device. This refrigeration cycle does not require refrigerants. Moving parts, no noise, no vibration, no wear, but it has high cost, low efficiency, complex manufacturing, and must use direct current, these shortcomings limit its promotion and application
