Embodiment Construction
[0025] figure 1 It is a relationship diagram of the semiconductor refrigeration sheet-cooling capacity-voltage in a semiconductor refrigerator according to an embodiment of the present invention, which shows the variation curve of the cooling efficiency of the semiconductor refrigeration sheet with the power supply voltage and the cooling capacity of the semiconductor refrigeration sheet with From the variation curve of the power supply voltage, it can be seen that the area between the voltage value V1 and the voltage value V3 is the area with the highest cooling efficiency of the semiconductor refrigeration sheet (in this embodiment, it can be called the high cooling efficiency section), and point A is the highest cooling efficiency area. The best working point, the cooling efficiency of the semiconductor refrigeration chip at point A is the highest, and the voltage at point A is recorded as V2. The area between the voltage value V3 and the voltage value V4 is that the refrig...

The invention discloses a semiconductor refrigerator. The semiconductor refrigerator comprises at least one semiconductor refrigerating plate and a power supply system used for supplying power for the semiconductor refrigerating plate, wherein the power supply system comprises a plurality of power supply conversion devices, the voltage output ranges of the power supply conversion devices are different, and the power supply conversion devices are electrically connected with the semiconductor refrigerating plate in a controlled mode. When using the semiconductor refrigerator, the power supply conversion device which meets the power supply requirements of the semiconductor refrigerating plate is selected from the power supply conversion devices with different voltage output ranges to supply power, and the high energy consumption of the semiconductor refrigerator due to the low power supply conversion efficiency when a wide-voltage range power supply conversion device outputs under a too low voltage or a too high voltage is avoided.
