▎ 摘　　要

NOVELTY - Liquid cooling plate based on coating graphene comprises an upper substrate, a lower substrate, and a graphene coating layer. The upper substrate is provided with a groove, and the upper substrate and the lower substrate form a flow channel for flowing the cooling liquid through the groove. The flow channel is respectively connected with the liquid inlet and the liquid outlet. The coating graphene is set on one surface of the lower base substrate far away from the upper base substrate, the coating graphene provided with concave unit micro-structure arranged in array, the upper and lower bases are connected together by rolling, and form the flow channel by blow molding. USE - Liquid cooling plate based on coating graphene preparation method for power battery used in electric automobile. Can also be used in battery pack module, motor and electric control service life. ADVANTAGE - The plate is good for increasing the heat exchange area for fully radiating and heat transfer, improving the radiating effect of the liquid cooling plate, has good whole forming property, can effectively avoid the carbon and aluminum to react at high temperature to form brittle phase, improve the strength and thermal conductivity of the aluminum plate, has good heat conducting performance, and is good for blowing and forming. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a preparation method of liquid cold plate based on coating graphene. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a liquid cooling plate of based on coating graphene. 1Upper substrate 2Lower substrate 3Graphene coating 4Flow channel 5Liquid inlet 6Outlet
