HEAT EXCHANGER AND HEAT EXCHANGE SYSTEM

Document Type and Number:

WIPO Patent Application WO/2021/018126

Kind Code:

A1

Abstract:

Disclosed is a heat exchanger (100, 200), comprising a first header (11), a plurality of heat exchange tubes (20), and a partition plate (104). The plurality of heat exchange tubes (20) are substantially arranged in parallel, are distributed in the axial direction of the first header (11), and are inserted into the first header (11). By means of the partition plate (104), a first inner cavity (101) of the first header (11) is divided into a first sub-cavity (1111) and a second sub-cavity (1112); one end of each heat exchange tube (20) is in communication with the first sub-cavity (1111); in the process of a refrigerant entering the first header (11), the refrigerant firstly flows into the second sub-cavity (1112) where same interacts with the heat exchange tubes (20) inserted into the second sub-cavity (1112) to create a violent turbulence effect, and same then flows into the first sub-cavity (1111) by means of through holes (1042) provided in the partition plate (104) so as to flow into the heat exchange tubes (20), such that the distribution uniformity of the two-phase of refrigerant is correspondingly improved.
