AI Technical Summary

Technical Problem

The existing three-media microchannel heat exchangers have complex connection pipeline structures and difficult brazing process, and the heat exchange efficiency of the advection flat tube group is low and the heat exchange is uneven.

Method used

The alternate arrangement of the advection flat tube group and the folded flat tube group is adopted to increase the heat exchange area with the advection flat tube and the spacer area by folding the flat tube, and a sub-flow channel is provided in the fins to increase the heat exchange area of ​​the third flow medium.

Benefits of technology

The heat exchange effect of the multi-media microchannel heat exchanger is improved, and the cooling capacity or heat emitted after the heat exchange of the first flow medium and the second flow medium is realized, and the use of auxiliary heat exchangers such as refrigerants is reduced, and the heat exchange cost is saved.

Abstract

The invention provides a multi-medium micro-channel heat exchanger which at least comprises an advection flat pipe set, a first micro-channel heat exchanger and a second micro-channel heat exchanger, the advection flat pipe set comprises a plurality of spaced advection flat pipes, and the advection flat pipes are all used for circulating a first circulating medium; the folding flat pipe group comprises a plurality of folding flat pipes which are arranged at intervals, and the folding flat pipes are all used for circulating a second circulating medium; the plurality of advection flat pipes and the plurality of folding flat pipes are alternately arranged, any advection flat pipe is attached to one folding flat pipe adjacent to the advection flat pipe and is spaced from the other folding flat pipe adjacent to the advection flat pipe, and any folding flat pipe is attached to one advection flat pipe adjacent to the folding flat pipe and is spaced from the other advection flat pipe adjacent to the folding flat pipe. According to the technical scheme, the heat exchange effect of the multi-medium micro-channel heat exchanger is improved.
