Wall-mounted indoor unit and air conditioner

Abstract

The invention discloses a wall-mounted indoor unit and an air conditioner. The wall-mounted indoor unit comprises a housing and a single-row heat exchanger, and the housing is provided with an air inlet, an air outlet and a heat exchanging air duct used for communicating the air inlet and the air outlet; the single-row heat exchanger is installed in the heat exchanging air duct, the single-row heat exchanger has V-shaped arrangement and comprises a front heat exchanger and a rear heat exchanger, the front heat exchanger comprises a front fin, the rear heat exchanger comprises a rear fin, multiple first wind blocking structures are distributed on the front fin and the rear fin in the length directions of the front fin and the rear fin at intervals, a second wind blocking structure is arranged at the connecting position of the front fin and the rear fin, and the second wind blocking structure is located between the first wind blocking structures arranged at the upper ends of the front fin and the rear fin. By means of the wall-mounted indoor unit, the wind speed difference of different parts of the single-row heat exchanger is reduced, so that the heat exchanging efficiency of the single-row heat exchanger is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a wall-mounted indoor unit and an air conditioner. Background technique [0002] In the prior art, in order to make the outlet air temperature more uniform after heat exchange by the heat exchanger, the wall-mounted indoor unit usually adopts a double-row heat exchanger. Due to the use of double-row heat exchangers, when the distance between the plates of the heat exchangers is too dense, the wind resistance will be large, and the fans, especially the cross-flow fans, need to overcome the large resistance, which will cause the fans to have small air volume, high power, and loud noise. problems, leading to low user experience comfort. At the same time, the cost of using double-row heat exchangers is also relatively high. In view of this, there are more and more studies on single-row heat exchangers. [0003] However, since the fins used in traditional heat exchangers a...

Problems solved by technology

[0003] However, since the fins used in traditional heat exchangers are usually in the form of single fins (flat fins, louvers, bridge fins, corrugated fins, etc.), this will cause differences in wind speeds flowing through different parts of the single-row heat exchanger. Larger, it will affect the heat exchange effect of different parts of the single-row heat exchanger, thereby reducing its overall heat exchange efficiency
