Problems solved by technology

[0005] 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

A heat exchanger comprises a first collecting pipe and a second collecting pipe which are arranged parallelly at intervals, heat exchange pipes of which the two ends are respectively connected with the first collecting pipe and the second collecting pipe so as to allow the first and the second collecting pipes to be communicated, and a plurality of fins which are respectively arranged between the adjacent heat exchange pipes, wherein, only one side of at least one fin is connected with the heat exchange pipes in the lengthwise direction of the first and second collecting pipes; the fin connected with the heat exchange pipes on one side of the fin comprises a first sub fin and a second sub fin; only one side of the first sub fin is connected with one of two adjacent heat exchange pipes in the lengthwise direction, whereas only one side of the second sub fin is connected with the other one of two adjacent heat exchange pipes; and the other sides of the first and second sub fins are opposite. The heat exchanger provided by the invention can avoid tearing fin when bending, ensure the integral appearance and improve the heat exchange performance.

Description

[0001] This application is a divisional application with the application number "201010298747.1", the filing date "September 29, 2010", and the title of the invention "a heat exchanger". technical field [0002] The invention relates to a heat exchanger. Background technique [0003] 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. [0004] European patent application EP1962040A1 describes a bending stress relief ...
