▎ 摘　　要

NOVELTY - The plate has a carbon coating layer fixed on a liquid cooling plate main body. The material of the liquid cooling board main body is metal aluminum, and the raw material of carbon coating is graphene carbon nanotubes composite material. The liquid cooling panel main body includes a lower cold plate, an upper cold plate and a liquid inlet nozzle. A liquid outlet nozzle is fixed on the lower cold board. The upper cold board is arranged above the lower cooling board. A carbon coating sheet is arranged on the upper top surface of the upper cooling board, and a groove is provided in the middle of the lower cool board. An air flow channel is formed between the bottom surface and the two side surfaces of the groove and the lower and lower bottom surface of an upper cool board to form a flow channel, and cooling agent is filled in the flow channel. The flow channel and the flow outlet nozzle are sequentially connected sequentially to form the loop. USE - Composite liquid cooling plate for radiating battery system. ADVANTAGE - The composite liquid cooling plate has good heat-conducting graphene material and carbon nano-tube material and good heat radiation performance of the carbon atom. The transverse heat conducting coefficient and surface heat radiation capability are improved. The battery system is radiated quickly. The performance and safety of the battery system can be improved. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method of composite liquid cooling plate for radiating battery system. DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of a composite liquid cooling plate for heat dissipation of a battery system. 51Lower cold plate 52Upper cooling plate 53Carbon coating 56Flow passage
