Document Type and Number:
WIPO Patent Application WO/2022/143393
Kind Code:
A1
Abstract:
Disclosed is a heat exchanger. The heat exchanger comprises: a collecting pipe that comprises a collecting pipe wall; and a plurality of flat pipes. The plurality of flat pipes comprise two groups of first flat pipes, which are positioned on the outermost side in an axial direction of the collecting pipe, and a second flat pipe, which is positioned between the two groups of first flat pipes; and the collecting pipe comprises two first parts, which correspond to the two groups of first flat pipes in the axial direction of the collecting pipe, and a second part, which is positioned between the two first parts. The tensile strength of at least one group of first flat pipes from the two groups of first flat pipes in the axial direction of the collecting pipe is greater than the tensile strength of the second flat pipe in the axial direction of the collecting pipe and/or the tensile strength of at least one first part from the two first parts of the collecting pipe in the axial direction of the collecting pipe is greater than the tensile strength of the second part of the collecting pipe in the axial direction of the collecting pipe. By means of the heat exchanger in the present invention, the bursting strength of the heat exchanger can be improved.
