Abstract

The invention provides a connecting piece and a microchannel heat exchanger. The connecting piece comprises a first side plate and a second side plate, and an arc plate connected between the first side plate and the second side plate; multiple parallel communicating channels (1), isolated from each other, are arranged in the connecting piece; each communicating channel (1) extends from the first side plate to the second side plate; one or more first heat exchange pipe joints (2) communicating with the communicating channels (1) are arranged on the outer side of the first side plate; and one ormore second heat exchange pipe joints (3) communicating with the communicating channels (1) are arranged on the outer side of the second side plate. The connecting piece can solve the problem of influence on the performance and the life of the heat exchanger by thinning of the outer walls of heat exchange pipes due to bending of the heat exchanger in the prior art.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a connecting piece and a microchannel heat exchanger. Background technique [0002] In general, common microchannel heat exchangers are flat and rectangular. However, in order to increase heat transfer performance and meet different application and installation requirements, the microchannel heat exchanger will also be made into an A-shaped structure. [0003] However, due to the size limitation of production equipment, especially the brazing furnace, the microchannel heat exchanger is usually brazed in the form of a flat rectangle, and then bent to form a corresponding bending angle. [0004] In the Chinese invention patent application with the application number 201310681338.3, a bending heat exchanger and a bending method of the heat exchanger are disclosed. The bending heat exchanger includes a first header, a second header, several Fins and several flat tubes, the...
