The invention relates to a semiconductor cooling refrigerator and a manufacturing method for the same. The semiconductor cooling refrigerator comprises an inner container, a semiconductor module and at least one cold-end heat tube for transferring the cold of the semiconductor module to the inner container, wherein the inner container of the semiconductor cooling refrigerator particularly comprises a graphite film layer which is arranged on at least a part of the outer surface of a substrate layer of the inner container to dissipate the cold of at least a part of an evaporation section of each cold-end heat tube to the outer surface of the substrate layer of the inner container. In addition, the invention further provides the manufacturing method for the semiconductor cooling refrigerator. According to the semiconductor cooling refrigerator and the manufacturing method for the same, the graphite film layer is arranged on at least a part of the outer surface of the substrate layer of the inner container, and can be used for uniformly dissipating the cold of at least a part of the evaporation section of each cold-end heat tube to the outer surface of the substrate layer of the inner container, so that the cooling uniformity of a storage room is achieved, and the cooling efficiency and cooling effects of the semiconductor cooling refrigerator are remarkably improved.

Description

technical field [0001] The invention relates to a refrigerator, in particular to a semiconductor refrigeration refrigerator and a manufacturing method thereof. Background technique [0002] Traditional refrigerators use Freon as the refrigerant and compressors as the driving force for the internal working medium circulation of the refrigerator. There are pollution problems such as ozone layer destruction, which does not meet the national environmental protection requirements. Semiconductor refrigeration, also known as thermoelectric refrigeration, thermoelectric refrigeration. Compared with traditional vapor compression refrigeration methods, semiconductor refrigeration does not require compressors and refrigerants, and has the advantages of rapid refrigeration start-up, simple structure, and no noise. Therefore, it is considered to be an environmentally friendly refrigeration method that helps to solve the problem of ozone destruction. At the same time, semiconductor refri...

Problems solved by technology

[0003] At present, most semiconductor refrigerators on the market use cooling aluminum grooves or heat pipe sleeve fins as cooling modules, and perform forced convection cooling under the action of axial fans. The temperature of the hot end and the air temperature in the refrigerated room, but there are also some problems, such as the forced convection axial flow fan needs to consume extra power, and as the axial flow fan’s running time increases, the noise and failure rate it generates also increase. It is getting bigger and bigger, which affects the comfort of the room. In addition, if forced convection cooling is used in the refrigerator room, it is necessary to slot the aluminum liner, which is likely to cause leakage of cooling capacity.
