Abstract

The embodiment of the invention provides a heat exchanger fin. The head exchanger fin comprises a substrate and a plurality of bridge pieces arranged on the substrate and used for cutting heat exchange airflow, and the bridge pieces are provided with bridge piece holes penetrating through the bridge pieces in the thickness direction. According to the heat exchanger fin, the bridge piece holes are formed in the bridge pieces, so that a boundary layer of heat exchange airflow flowing through the heat exchanger fin is further damaged, the air side convection heat transfer coefficient is effectively increased, heat resistance is remarkably reduced, pressure drop is reduced, and the heat exchange effect of the heat exchanger fin is further improved.

Description

technical field [0001] The invention relates to the field of electrical appliances, in particular to a heat exchanger fin, a heat exchanger, a heat pump system and electrical equipment. Background technique [0002] A heat exchanger is a device that transfers part of the heat of a hot fluid to a cold fluid, also known as a heat exchanger. [0003] The finned heat exchanger achieves the purpose of enhancing heat transfer by adding fins to the heat dissipation tubes used to transmit fluids. [0004] In the related art, the heat exchange efficiency of the traditional finned heat exchanger is not high, and the pressure drop is relatively large. Contents of the invention [0005] In view of this, the embodiment of the present application expects to provide a heat exchanger fin capable of improving heat exchange effect. [0006] In order to achieve the above-mentioned purpose, the technical scheme of the embodiment of the present application is realized in this way: [0007] ...
