Heat exchanger and air conditioner comprising same

Abstract

The invention discloses a heat exchanger and an air conditioner comprising the same. The heat exchanger comprises a first flow collection tube, a second flow collection tube and a plurality of heat exchange tubes, wherein the first flow collection tube and the second flow collection tube are arranged in a spaced mode; the heat exchange tubes are arranged in the length direction of the first flow collection tube at the intervals; the two ends of each heat exchange tube are connected with the first flow collection tube and the second flow collection tube correspondingly; a protective plate is arranged at least one side of the heat exchange tubes in the length direction of the first flow collection tube; the protective plate is located on the outermost side of the heat exchange tubes; and atleast part of fins are connected between the protective plate and the heat exchange tube nearest to the protective plate. According to the heat exchanger provided by the invention, the fins of the heat exchanger can be protected against fin collapse during transportation.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a heat exchanger and an air conditioner with the same. Background technique [0002] Due to the design of the drainage structure of the fin itself, the strength of the end of the fin is relatively weak. During the production process of the heat exchanger, welding, leak detection and assembly are required. When personnel or machines are transferred, the end of the fin is likely to be inverted. In addition, when the product is transported or dropped, it is easy to cause the fins at the bottom to fall back, resulting in low heat exchange efficiency of the heat exchanger, especially in the defrosting process of low-temperature heating conditions, the frost layer at the end of the flip is thicker, The inverted structure is not conducive to drainage. The frost layer does not completely melt into water within the specified time, and part of it slides off in sheets and accumulat...

[0002] Due to the design of the drainage structure of the fin itself, the strength of the end of the fin is relatively weak. During the production process of the heat exchanger, welding, leak detection and assembly are required. When personnel or machines are transferred, the end of the fin is likely to be inverted. In addition, when the product is transported or dropped, it is easy to cause the fins at the bottom to fall back, resulting in low heat exchange efficiency of the heat exchanger, especially in the defrosting process of low-temperature heating conditions, the frost layer at the end of the flip is thicker, The inverted structure is not conducive to drainage. The frost layer does not completely melt into water within the specified time, and part of it slides off in sheets and accumulates at the bottom of the heat exchanger, which affects the normal operation of the next heating cycle and further affects the reliability of the heat exchanger. sex
