NOVELTY - The utility model claims a superconducting plate with graphene heat conducting layer, comprising a substrate made of aluminium or aluminium alloy, substantially along the horizontal direction is provided with a row of heat conducting hole; the inner wall of the heat conducting hole is provided with a graphene layer; two ends of the heat conducting hole are sealed. the heat conducting hole comprises multiple round heat conducting holes in the middle of the base plate and round, and multiple square heat conducting holes with square sections on two sides of the round heat conducting hole. the circumferential edge of the base plate is wrapped with a plastic frame; a sealing strip is pressed between the upper frame and the lower frame. The utility model abandons the structure of three layers bonding, even if repeatedly cooling and heating for many times, the structure intensity is still not affected, compared with the past, it greatly improves the service life. the inner wall of the heat-conducting hole is provided with a graphene layer; compared with the conventional graphene layer provided with a horizontal layer, the area of the graphene layer is 2-4 times of the area of the single-layer horizontal graphene layer, so it can greatly improve the heat transfer speed, and improve the cooling speed and the thawing speed.
