Abstract

The invention offers a kind of heat exchanger. Its structure comprises secondary refrigerant pipe in which the secondary refrigerant is flowed, many cooling fins fixed on the secondary refrigerant pipe, fan electromotor and air blow fan forcibly transported the outside air to the fan secondary refrigerant pipe and the cooling fins. The secondary refrigerant pipe is dropped down the direction of air exhaust of the air blow fan and inclined with the ground. The advantage of the invention is that the secondary refrigerant pipe is inclined to make the thickness of the liquid state secondary refrigerant form to uniform in the up-down part of the secondary refrigerant pipe; the exchange capacity of the liquid state secondary refrigerant flowed in the secondary refrigerant pipe and gaseous heat is increased; in the heat exchanger with certain space, the flow path of the secondary refrigerant is only changed to sharply improve the heat exchange performance.

Description

technical field [0001] The present invention relates to an invention of a heat exchanger, and in particular relates to an invention applicable to a heat exchanger on a refrigerator or an air conditioner. Background technique [0002] Usually, the refrigerant of refrigerators and air conditioners undergoes a cooling cycle of compression-condensation-expansion-evaporation to generate cold air, which makes food fresh or cools the room. [0003] Such as figure 1 As shown, it is a structural diagram of a cooling heat exchanger used when cooling the high-temperature and high-pressure refrigerant discharged from the compressors of equipment such as refrigerators and air conditioners. S-shaped refrigerant pipe 3a; a plurality of cooling fins 3b arranged vertically on the refrigerant pipe 3a to expand the heat exchange area. [0004] In order to successfully complete the condensation process of the above-mentioned condensing heat exchanger 3 , a blower fan 1 and a fan motor 2 are a...
