Micro-channel heat exchanger and partition plates thereof

Abstract

The invention provides a micro-channel heat exchanger and partition plates thereof. The partition plates are used for sealing a liquid collecting tube of the micro-channel heat exchanger. Each partition plate comprises a first plate and a second plate with the ends connected rotatably. A boss which is used for abutting against the inner wall of the liquid collecting tube to limit the separation of the partition plates and the liquid collecting tube is arranged on the first plate and the second plate respectively. The bosses are arranged on the sides of the first plates away from the second plates and the sides of the second plates away from the first plates. By means of the partition plates, the bosses are snapped with the inner wall of the liquid collecting tube, and accordingly, the partition plates are fixedly connected with the liquid collecting tube, compared with partition plate fixing in a riveting mode in the prior art, riveting is not needed, only the partition plates are inserted in the liquid collecting tube directly, the partition plates can be mounted conveniently, the partition plate mounting efficiency is improved, and the whole micro-channel heat exchanger production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of micro-channel heat exchangers, and more specifically relates to a micro-channel heat exchanger and a partition plate thereof. Background technique [0002] Due to the advantages of energy saving and outstanding heat transfer performance, microchannel heat exchangers are gradually being widely used. At present, the micro-channel heat exchanger mainly uses circular tubes as the header, and a partition is set in the header to divide the flow channel of the micro-channel heat exchanger into several processes to realize flow interception and then flow diversion. Usually, a flat-plate partition is used (the partition is a flat plate), and the partition is set on the installation groove in the collecting pipe, and the partition is fixed on the collecting pipe by riveting. [0003] However, the partition plate is fixed by riveting, so that the installation efficiency of the partition plate is low, resulting in l...

AI Technical Summary

Problems solved by technology

[0003] However, riveting is used to fix the partition, which makes the installation efficiency of the partition low, resulting in low production efficiency of the entire microchannel heat exchanger

[0004] In addition, during the riveting process of fixing the partition, it is necessary to apply external force to the collecting pipe, which produces irreversible deformation on the collecting pipe, and it is easy to cause a gap between the partition and the inner wall of the collecting pipe, and the installation reliability is poor. Unable to achieve the design interception effect
