Abstract

The invention discloses a heat exchanger, comprising a first collecting pipe, a second collecting pipe, a flat pipe and a fin, wherein, the first collecting pipe is arranged vertically; the second collecting pipe is arranged in parallel with and opposite to the first collecting pipe and a preset distance is spaced out therebetween; the flat pipe is arranged between the first collecting pipe and the second collecting pipe horizontally and the two ends are respectively communicated with the first collecting pipe and the second collecting pipe; the fin is generally in a corrugated shape and is arranged between adjacent flat pipes; the fin comprises a straight line segment and a join segment which are connected in turn to ensure that the join segment forms a wave crest and a wave trough; the first end of the fin stretches out from one side of the flat pipe along the transverse direction; and the join segment in the first end part is removed. The heat exchanger in the invention can improvethe drainage performance, improve the surface heat exchanging of the heat exchanger and reduce the waste work of an air blower.

Description

technical field [0001] The invention relates to a heat exchanger, in particular to a microchannel heat exchanger capable of improving the performance of discharging condensed water. Background technique [0002] For example, when a parallel flow heat exchanger is used as an evaporator or a heat pump heat exchanger, condensed water will be generated on the surface. In order to improve the performance of the heat exchanger to discharge condensed water, the parallel flow heat exchanger usually adopts horizontal headers and flat tubes Install vertically between headers. [0003] However, the above-mentioned conventional arrangements of headers and flat tubes are not suitable for certain types of heat exchangers, such as prolate heat exchangers (ie, heat exchangers whose length is much greater than their height). [0004] For flat and long heat exchangers, if the above-mentioned traditional setting method is adopted, the following problems will be brought about: [0005] The he...
