Problems solved by technology

[0003] At present, air-conditioning heat exchangers usually use straight heat exchange fins. This type of heat exchange fins is along the direction of air flow, and the boundary layer formed by the air on the surface of the heat exchange fins will gradually thicken, making the air velocity and stability gradient The synergy becomes worse, which reduces the heat transfer performance

Abstract

The embodiment of the invention provides a heat exchange fin, a heat exchanger and an air conditioner and relates to the technical field of air conditioners. The heat exchange efficiency of the heat exchange fin can be improved. The heat exchange fin comprises a substrate, wherein a pipe hole of which the edge is turned towards one side is formed in the substrate; the substrate comprises a plurality of stepped platforms; the adjacent stepped platforms are connected with each other by a transition plane; the pipe hole is formed in the middle stepped platform; in the extension direction of the plurality of stepped platforms, the stepped platforms on two sides of the middle stepped platform are opposite in height change tendency. The embodiment of the invention is applied to manufacturing of the heat exchanger of the air conditioner.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a heat exchange fin, a heat exchanger and an air conditioner. Background technique [0002] With the establishment of new energy efficiency standards for inverter air conditioners, the APF (Annual Performance Factor, annual energy consumption efficiency) evaluation index has been introduced into the energy efficiency standards for inverter air conditioners, which not only considers the cooling capacity of air conditioners but also includes heating factors. Compared with the previously adopted SEER (seasonal energy efficiency ratio (seasonal energy efficiency ratio) standards, put forward more comprehensive requirements for the energy-saving level of the overall air-conditioning products, greatly increase the entry threshold of products, put forward higher requirements for air-conditioning manufacturers in matching refrigeration systems, and for air-conditioning replacemen...
