Title:
HEAT EXCHANGER AND PROCESSING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/041250
Kind Code:
A1
Abstract:
Disclosed in embodiments of the present application are a heat exchanger and a processing method therefor, wherein a heat exchange tube of the heat exchanger comprises a curved section, a first section and a second section; the curved section comprises a section to be curved before bending, and the section to be curved comprises a protruding section; the heat exchange tube comprises a first surface, a second surface, a third surface and a fourth surface; the first surface and the third surface intersect at a first side edge; before the curved section is bent, a plane, which is parallel to the length direction of a first tube, parallel to the length direction of the first section, and perpendicular to the width direction of the first section, is defined as a first plane; and in the first plane, the minimum distance from a projection line of a first side edge of the protruding section to a projection line of a first side edge of the first section is H, and the minimum distance from the projection line of the first side edge of the first section to a projection line of a first side edge of an adjacent other first section is L, where H≥L. By means of the heat exchanger of the embodiments of the present application, the friction between adjacent curved sections during bending and the risk of accumulating water and dust during the use of a product are reduced, and the reliability of a heat exchange tube is improved.
