Abstract

The invention discloses an air conditioner. The air conditioner comprises a heat exchanger; the heat exchanger comprises a plurality of fins; the fins are provided with heat pipe inserting parts; a first flowing area, a second flowing area and a third flowing area are sequentially formed on the fins in the flowing direction of heat exchange media; first corrugated parts and second corrugated parts are alternately arranged in the first flowing area at intervals; third corrugated parts are arranged in the second flowing area; the heat pipe inserting parts are located in the second flowing area; the heat pipe inserting parts and the third corrugated parts are alternately arranged; fourth corrugated parts and fracture parts are alternately arranged in the third flowing area at intervals; the fracture parts are opposite to the first corrugated parts and the third corrugated parts in position; second flow channels arranged in the flowing direction of the heat exchange media are formed among the first corrugated parts, the third corrugated parts and the fracture parts of adjacent fins; and the second flow channels can reduce the frosting amount of the fins on a windward side and enable frost to be condensed at the fracture parts. The problems that an existing air conditioner heat exchanger is low in heat exchange coefficient, high in frosting rate and prone to blocking an air duct are solved.

Description

technical field [0001] The invention belongs to the technical field of household appliances, and in particular relates to an improvement of the structure of an air conditioner. Background technique [0002] When the air conditioner operates in a low-temperature and high-humidity environment, the frosting rate of the outdoor unit is too fast and the defrosting interval is short, which adversely affects the heating comfort of the room and the energy efficiency of the air conditioner. From the perspective of heat exchangers, the outdoor units of existing air conditioners generally adopt two forms of flat fins or slotted fins, of which the flat fins have a low heat transfer coefficient under condensation conditions, resulting in poor heat transfer performance; The thermal coefficient is high, but the finned air duct is prone to frost blockage under low-temperature evaporation conditions, which makes the heat transfer performance attenuate sharply. [0003] Existing fin forms, s...
