Abstract

The invention provides a heat exchanger and a household appliance. The heat exchanger comprises an inlet portion, an outlet portion and a heat exchange structure connected between the inlet portion and the outlet portion. The inlet end of the heat exchange structure is connected with the inlet portion. The outlet end of the heat exchange structure is connected with the outlet portion. The heat exchange structure comprises multiple layers of heat exchange row pieces. The multiple layers of heat exchange row pieces are formed by bending single flat pipes and arranged in the first direction. Each layer of heat exchange row pieces comprises multiple straight sections arranged at intervals in the second direction perpendicular to the first direction and bent sections for being connected with the adjacent straight sections. By the adoption of the heat exchanger and the household appliance, a refrigerant flows in the heat exchange structure more uniformly, and the heat exchange efficiency of the heat exchanger is improved.

Description

technical field [0001] The invention relates to the field of heat exchange devices, in particular to a heat exchanger and a household appliance. Background technique [0002] With the development of the national economy and the improvement of people's living standards, various home appliances have entered the homes of ordinary people, such as washing and drying machines, refrigerators, freezers, air conditioners, heat pump water heaters and dishwashers. Heat exchanger is a tool to realize heat transfer between cold and hot fluids, and microchannel heat exchanger has the advantages of low cost, small pressure resistance, compact structure, light weight and good heat transfer performance, so it is more and more popular in the home appliance refrigeration industry of favor. [0003] figure 1 It is a schematic diagram of the structure of a typical microchannel heat exchanger. Such as figure 1 As shown, the microchannel heat exchanger structure of this structure includes an i...
