Semiconductor refrigeration refrigerator

Abstract

The invention provides a semiconductor refrigeration refrigerator. Specifically, the semiconductor refrigeration refrigerator provided by the invention comprises an inner container, at least one semiconductor refrigerating sheet and a plurality of cold-end heat exchanging devices, wherein each cold-end heat exchanging device is configured to exist a flow and a phase-change heat exchange of refrigerant in the cold-end heat exchanging device so as to transfer cold at an cold end of the at least one semiconductor refrigerating sheet to a storage chamber of the inner container. Specifically, each cold-end heat exchanging device is provided with three refrigerant pipelines, each refrigerant pipeline is provided with an evaporating segment with a closed end, the evaporating segment extends downwards in a vertical plane in a bent manner, and evaporating segments of the three refrigerant pipelines of each cold-end heat exchanging device are respectively connected to a rear wall and two side walls of the inner container in a thermal manner. According to the semiconductor-refrigerated refrigerator provided by the invention, as the plurality of cold-end heat exchanging devices are provided, effective heat exchange area in thermal connection with the inner container of the refrigerator is enlarged significantly, and therefore energy efficiency of the semiconductor refrigeration refrigerator is improved significantly.

[0003] However, semiconductor refrigeration refrigerators need to effectively conduct the temperature of the cold end of the semiconductor refrigeration sheet to the storage room of the refrigerator. The existing technology generally adopts the forced convection of the heat sink. Chamber for heat exchange, the heat conduction and heat exchange efficiency between solids is low, which is not conducive to the best performance of semiconductors, and the cooling fins are large in size, occupying the space of the refrigerator, and the noise will increase when the fan is used. work, less reliable
