Title:
HEAT EXCHANGER
Document Type and Number:
WIPO Patent Application WO/2021/082618
Kind Code:
A1
Abstract:
Disclosed is a heat exchanger, comprising: at least three heat exchange tube groups (10), the heat exchange tube groups (10) being connected in sequence, at least two heat exchange tube groups (10) being attached to each other along the direction in which the heat exchange airflow flows, the medium sequentially flowing through each heat exchange tube group (10) and forming a U-shaped trajectory; an intermediate adapter portion (20), at least two heat exchange tube groups (10) being communicated with each other by means of the intermediate adapter portion (20), the intermediate adapter portion (20) comprising at least two adapters (21) and an adapter tube (22) connecting two adjacent adapters (21), wherein each adapter (21) is composed of a first plate (211) and a second plate (212), the adapter tube (22) is an extruded flat tube, and the width direction of the adapter tube (22) is perpendicular to the width direction of the heat exchange tube groups (10); and an end adapter portion (30), which is located at the end of the attached heat exchange tube groups (10) away from the intermediate adapter portion (20), the attached heat exchange tube groups (10) being communicated with each other by means of the end adapter portion (30). The present heat exchanger solves the problem that A-type heat exchangers in the prior art cannot satisfy the use requirements and has the advantages such as high heat exchange performance and compact structure.
