▎ 摘　　要

NOVELTY - The heat exchanger has a cold and hot inlet plate (1) whose side is provided with a heat exchange main device (3). A side of the heat exchange main device far away from the cold and hot inlet plate is provided with a connecting plate (2). A top end of a side of the cold and hot inlet plate is provided with a cold source outlet (101). A bottom end of the cold and hot entering plate is provided with a heat source inlet. A side of the connecting plate far away from the cold and hot outlet plate is provided with an auxiliary pipe (201). A middle portion of the vent groove of the connecting plate is provided with a heat insulating layer. USE - Graphene micro-channel based heat exchanger. ADVANTAGE - The exchanger ensures that a graphene material covered on an outer surface of the first heat exchange main body, so that the graphene on the outer surface can quickly conduct heat of an aluminum material of a first heat-exchange main body to a surface, thus improving radiating effect of a heat exchange loose sheet in an efficient manner. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of a graphene micro-channel based heat exchanger.
