Abstract

The embodiment of the invention provides a micro-channel heat exchanger, a machining method thereof and an air conditioner. The micro-channel heat exchanger comprises a heat exchanger core body, a connecting pipe and a LokRing. The connecting pipe is inserted and communicated with a connecting pipe seat of the heat exchanger core body; and the LokRing sleeves the outer sides of the connecting pipe and the connecting pipe seat and is fixedly connected with the connecting pipe and the connecting pipe seat. The connecting pipe seat and the connecting pipe of the heat exchanger core body are fixedly connected together through the LokRing, and a conventional manual flame brazing connecting and fixing manner is replaced. Due to the fact that firm connection of the connecting pipe seat and the connecting pipe can be achieved under the normal temperature condition through the LokRing connecting manner, the operation difficulty is relatively low, the labor intensity is relatively small, and the influence of human factors is relatively small, the leakage problem caused by manual brazing operation skill fluctuation can be avoided, and the labor intensity of workers is reduced.

Description

technical field [0001] The present application relates to but is not limited to the processing technology of microchannel heat exchangers, and specifically refers to a microchannel heat exchanger, its processing method and an air conditioner. Background technique [0002] At present, the connection seat and the connection pipe of the microchannel heat exchanger (or parallel flow heat exchanger) are fixedly connected by manual flame brazing, which is greatly affected by human factors, unstable in quality, easy to cause leakage problems, and labor-intensive. Contents of the invention [0003] The technical problem to be solved in this application is to provide a micro-channel heat exchanger, which adopts a Lock ring to realize the fixed connection between the connecting seat and the connecting pipe, which can avoid the leakage problem caused by the fluctuation of manual brazing operation skills, and reduce the labor intensity. [0004] The technical solution for solving the ...
