Micro channel heat exchanger and heat exchanging device comprising it

摘要

The present invention is a printed board type heat exchanger, comprising: a first plate having a plurality of through-holes, a second plate having a plurality of through-holes disposed so as to alternate with the through-holes of the first plate, and an upper surface or a lower surface of the second plate Includes; a cover plate attached to. It may be formed by alternately stacking a plurality of first plates, a plurality of second plates, and a plurality of cover plates. According to the present invention, even if a portion of the flow path is blocked through the three-dimensional flow path, the fluid flows through other branches, so that the performance of the flow path does not decrease, and a plurality of holes are formed using a mold rather than an expensive etching process. By doing so, the manufacturing cost is low.
