Fin assembly, heat exchanger and air conditioner indoor unit

Abstract

The invention discloses a fin assembly, a heat exchanger and an air conditioner indoor unit. The fin assembly comprises a front fin and a rear fin, the fin assembly is provided with a first wind shielding part, second wind shielding parts and third wind shielding parts, the wind shielding areas of the first wind shielding part, the second wind shielding parts and the third wind shielding parts aredecreased in sequence, and the first wind shielding part is arranged at the connecting position of the front fin and the rear fin; the front fin comprises a first row of wind shielding assemblies anda second row of wind shielding assemblies which are distributed along the wind inlet side to the wind outlet side, the first row of wind shielding assemblies comprises the multiple second wind shielding parts and the multiple third wind shielding parts which are all sequentially distributed in the direction, away from the top of the fin assembly, of the front fin, and the second row of wind shielding assemblies comprises the multiple third wind shielding parts; and / or the rear fin comprises a third row of wind shielding assemblies and a fourth row of wind shielding assemblies, the third row of wind shielding assemblies and the fourth row of wind shielding assemblies are distributed along the air inlet side of the rear fin to the air outlet side of the rear fin, the third row of wind shielding assemblies comprises the multiple second wind shielding parts and the multiple third wind shielding parts which are sequentially distributed in the direction, away from the top of the fin assembly, of the rear fin, and the fourth row of wind shielding assemblies comprises the multiple third wind shielding parts. According to the fin assembly, the structure of the fin assembly is improved, sothat wind speed distribution of the fin assembly is more uniform.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a fin assembly, a heat exchanger and an indoor unit of the air conditioner. Background technique [0002] In the prior art, the heat exchanger of the indoor unit of the air conditioner includes a plurality of fins arranged side by side and a plurality of heat exchange tubes pierced on the plurality of fins, and the plurality of heat exchange tubes are connected to form a pipeline for refrigerant circulation. When the air conditioner is cooling, the refrigerant in the heat exchange tube absorbs heat through evaporation to reduce the temperature of the air flowing through the heat exchanger, thereby achieving the purpose of cooling. [0003] However, according to the structure of the indoor unit of the air conditioner, the wind speed of each part of the fin assembly of the heat exchanger is different, which will cause the heat exchange efficiency of each part of the fin as...
