Abstract

The invention relates to the technical field of heat exchange, and discloses a heat exchanger. The heat exchanger comprises a heat dissipation element, a refrigerant pipe and an electromagnetic heating element; the refrigerant pipe is arranged on the heat dissipation element in a penetrating manner; and the electromagnetic heating element comprises an electromagnetic heating pipe and a coil arranged outside the electromagnetic heating pipe, and the electromagnetic heating pipe is communicated with the refrigerant pipe. According to the heat exchanger, the electromagnetic heating element heats a refrigerant at the electromagnetic heating pipe and transfers the heat to the refrigerant at the refrigerant pipe of the heat exchanger, and the heat of the high-temperature refrigerant defrosts the whole heat exchanger. According to the electromagnetic heating element, in the defrosting process of the heat exchanger, most of heat generated by the electromagnetic heating element acts on the heat exchanger, so that the heat loss is little, and the defrosting speed is improved. The invention further discloses a household appliance comprising the heat exchanger.

Description

[0001] The present application relates to the technical field of heat exchange, for example, to a heat exchanger and household appliances. Background technique [0002] At present, electric heating tubes are mostly used to defrost the heat exchanger. The defrosting of the electric heating tube relies on the heat radiation of the electric heating tube to defrost the heat exchanger. Install resistors with appropriate power on the heat exchangers of refrigerators and other household appliances. When the frost on the heat exchanger is serious and affect the use of refrigerators and other household appliances, turn on the electric heating tube, and the resistance wire of the electric heating tube will be energized to generate heat, and then Defrost the outer surface of the heat exchanger. [0003] In the process of implementing the embodiments of the present disclosure, it is found that there are at least the following problems in the related art: when the electric heating tube is...
