Embodiment Construction

[0021] The present invention will be further described below in conjunction with embodiment, but is not limited to the content on the description.

[0022] Such as figure 1 and figure 2 As shown, the present invention discloses a heat exchanger, including heat exchange coils 10 and cooling fins 20, heat exchange coils 10 are at least two groups, all heat exchange coils 10 are stacked, each group of heat exchange discs The tube 10 is an independent heat exchange pipeline; the cooling fins 20 are installed on the heat exchange coil 10 . The heat exchanger of the present invention is provided with multiple sets of heat exchange coils 10, and each set of heat exchange coils 10 is an independent heat exchange pipeline. Therefore, different heat exchange coils 10 can be controlled to exchange heat independently according to specific conditions. Or heat exchange at the same time, so as to adjust the cooling capacity, reduce the generation of frost layer, facilitate defrosting, and...

Abstract

The invention discloses a combined heat exchanger and a refrigerator. The heat exchanger comprises at least two heat exchange coils and radiating fins, all the heat exchange coils are overlapped, andeach heat exchange coil is an independent heat exchange pipe; and the radiating fins are arranged on the heat exchange coils. According to the heat exchanger, the plurality of heat exchange coils arearranged, and each heat exchange coils is the independent heat exchange pipe, so that different heat exchange coils can be controlled to exchange heat independently or simultaneously according to specific conditions, the refrigerating capacity is adjusted, frost layers are reduced, defrosting is convenient, and more energy is saved.

Description

technical field [0001] The invention relates to the technical field of refrigerators, in particular to a combined heat exchanger and refrigerator. Background technique [0002] At present, more and more air-cooled refrigerators have entered the homes of consumers. Frost-free refrigerators have the advantages of fast cooling speed, good temperature uniformity, and automatic defrosting. These advantages benefit from the use of fans to force convection, heat exchange, and evaporation The cooling capacity is obtained by the evaporator, and sent to each room of the refrigerator through the air duct to cool down. After a period of time, the frost on the evaporator is removed by the heater, and the refrigerator is drained through the drainage pipe. [0003] At present, many air-cooled refrigerators on the market use a refrigeration system that uses capillary throttling. Especially for fixed-frequency compressor products, the system refrigerant flow rate and cooling capacity cannot...
