Semiconductor refrigerator

Abstract

The invention provides a semiconductor refrigerator which comprises multiple semiconductor chilling plates and a power supply system supplying power for the semiconductor chilling plates. The semiconductor refrigerator is provided with multiple temperature areas, and each temperature area is refrigerated through one or more of the semiconductor chilling plates. The power supply system supplies power for the semiconductor chilling plates of the temperature areas respectively. According to the scheme, the semiconductor chilling plates refrigerate the temperature areas respectively, the power supply system supplies power for the semiconductor chilling plates of the temperature areas respectively, the refrigerating capacities of the semiconductor chilling plates are different due to the fact that different voltages are applied to the semiconductor chilling plates of the different temperature areas, the storage environments of different temperature areas with different temperatures are achieved, and the storage requirements of different goods are met. A source transformation device meeting the power supply requirement of the semiconductor chilling plates is selected from multiple source transformation devices with different voltage output ranges for power supply, and the energy consumption efficiency of the semiconductor refrigerator is improved.

AI Technical Summary

Problems solved by technology

That is to say, most semiconductor refrigerators have a single temperature zone, that is, the temperature inside the semiconductor refrigerator is the same, resulting in a single use of semiconductor refrigerators, which cannot meet the requirements for storing different types of items.

[0004] In addition, due to the wide operating voltage range of the semiconductor refrigerator, in some environments, the power conversion efficiency of the power conversion device is very low, resulting in a large energy consumption of the semiconductor refrigerator.

Moreover, a wide range of power conversion devices will also lead to increased costs
