The invention provides a heat exchanger. The heat exchanger comprises a heat exchange core body, a heat exchanger core body and a heat exchanger core body, the flow collecting pipe part is fixedly connected with the heat exchange core body, mounting end plates are formed on the first flow collecting pipe part and the second flow collecting pipe part, and inserting holes matched with the heat exchange pipes are formed in the mounting end plates; the mounting end plate is hermetically fixed with the tube wall of the heat exchange tube; inner cavities of the heat exchange pipes communicate with an inner cavity of the first collecting main part and an inner cavity of the second collecting main part. The outer shell comprises a first sub-shell and a second sub-shell, the first sub-shell and thesecond sub-shell are combined in the direction perpendicular to the extension direction of the outer shell, and the two sub-shells are sealed and fixed through bonding; the outer shell is provided with a first inner cavity, and at least part of the heat exchange core is contained in the first inner cavity; first openings are formed in the two opposite ends of the extending direction of the outershell correspondingly and communicate with the first inner cavity; and at the first opening, the outer shell and the mounting end plate are sealed and fixed through bonding. The reliability of the heat exchanger product can be improved.
Description
technical field [0001] The present application relates to the technical field of heat exchange, in particular to a heat exchanger and a manufacturing method thereof. Background technique [0002] In the related art, a heat exchanger is used as a device for exchanging heat between two fluids in a heat exchange system. The heat exchanger includes a heat exchange core composed of heat exchange tubes, an outer shell, and a header. The heat exchanger can form two kinds of fluid circulation areas that are not connected to each other through the cooperation of various parts. The various parts of the heat exchanger are mostly sealed and connected by brazing technology, but the brazing welding quality of the heat exchanger in the related art is poor, and the product leaks The problem of high defect rate. Contents of the invention [0003] The present application provides a heat exchanger and a manufacturing method thereof, which is beneficial to improving the reliability of heat e...
