Problems solved by technology

[0004] However, the disadvantage of this traditional bending stress relief structure is that: since the fins are replaced by bent guide rails, and there is no ventilation between the flat tubes with bent guide rails, the heat exchange effect is adversely affected, and the overall heat exchanger poor appearance

Abstract

The invention discloses a heat exchanger, which comprises first collecting pipes, second collecting pipes, heat exchange pipes and a plurality of fins, wherein the second collecting pipes and the first collecting pipes are arranged in parallel at intervals; two ends of the heat exchange pipes are connected with the first and second collecting pipes respectively to communicate the first and secondcollecting pipes; and the plurality of fins are arranged between the adjacent heat exchange pipes respectively, wherein only one side of at least one of the fins is connected with the heat exchange pipe in the longitudinal directions of the first and second collecting pipes. According to the heat exchanger of the embodiment of the invention, the fins are prevented from being torn during bending so as to ensure the integral appearance of the heat exchanger and improve the heat exchange performance.

Description

technical field [0001] The invention relates to a heat exchanger. Background technique [0002] In order to improve applicability, heat exchangers, such as parallel flow heat exchangers, often need to be bent along the axial direction of the header, such as bent into an L or C shape. When bending, the part outside the bend of the header is stretched, so that the distance between the heat exchange tubes on the outside of the bend is enlarged, so the fins between the heat exchange tubes are also stretched, which is easy to cause bending The fin part on the outer side of the bend is torn or separated from the heat exchange tube, which affects the heat exchange performance and appearance of the heat exchanger. [0003] European patent application EP1962040A1 describes a bending stress relief structure, in which the fins are removed between adjacent flat tubes in the bending area and replaced by bending guide rails, which are bent under the action of the bending guide rails duri...
