Heat exchanger for split type air conditioner and split type air conditioner with heat exchanger

Abstract

The invention provides a heat exchanger for a split type air conditioner. The heat exchanger comprises at least two heat exchange fins (1). Each heat exchange fin (1) comprises heat exchange holes (2), a windward side (11) obliquely arranged in the air inflow direction and strip-shaped crack protrusions (3) provided with first ends (31) and second ends (32), wherein the first ends (31) are located on the airflow upstream, and the second ends (32) are located on the airflow downstream. Each crack protrusion (3) is formed in the manner that at the position parallel to the windward side (11), the first ends (31) rotate around the second ends (32) by a preset angle in the airflow downstream direction. By means of the heat exchanger for the split type air conditioner, the projected area of cracks of the crack protrusions is increased in the direction perpendicular to the air inlet direction, the air inlet area of an airflow channel formed by a split type air conditioner indoor unit is increased effectively, the air circulation speed is increased, the heat exchange efficiency of the heat exchanger is improved, and the performance of the air conditioner is improved. The invention further relates to the split type air conditioner with the heat exchanger.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to a heat exchanger for a split-type air conditioner and a split-type air conditioner with the heat exchanger. Background technique [0002] In the indoor unit of the split-type air conditioner in the prior art, the heat exchanger is composed of mainly two to three heat exchangers spliced ​​together, and the angles formed by the heat exchangers are also different for different fan blade shapes and sizes. Not the same. The air intake area of ​​the airflow channel formed by the slit angle on the fins of the current heat exchanger is reduced, which easily reduces the flow velocity of the airflow, resulting in a decrease in the heat exchange efficiency of the heat exchanger. [0003] Since the heat exchanger of the split unit air conditioner in the prior art has technical problems such as the reduction of the air inlet area, the reduction of the flow rate of the ai...

Problems solved by technology

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defects that the heat exchanger of the indoor unit of the split-type air conditioner in the prior art has a reduced air intake area, resulting in a decrease in the flow velocity of the airflow and a decrease in the heat exchange efficiency of the heat exchanger. Thereby providing a heat exchanger for a split-type air conditioner and a split-type air conditioner having the same
