Title
(EN) A MICROCHANNEL HEAT EXCHANGER
(FR) ÉCHANGEUR THERMIQUE À MICROCANAUX
Abstract
(EN)
A microchannel heat exchanger comprising: at least one high temperature heat exchanging plate and at least one low temperature heat exchanging plate stacked in an alternating sequence, wherein an inlet of high temperature fluid and an outlet of high temperature fluid are disposed in order to pass the high temperature fluid through each said high temperature heat exchanging plate, and an inlet of low temperature fluid and an outlet of low temperature fluid are disposed in order to pass the low temperature fluid through each said low temperature heat exchanging plate, wherein the high temperature heat exchanging plate comprising the high temperature microchannel and the low temperature heat exchanging plate comprising the low temperature microchannel, wherein said channels have a length extending in the flow direction of fluids, and the side wall of each said channel has a symmetric wavy pattern with the center line of each said channel as a symmetric axis, wherein the high temperature heat exchanging plate and the low temperature heat exchanging plate are arranged in the pattern in which the high temperature microchannel and the low temperature microchannel are aligned.
