NOVELTY - A carbon substrate type heat collecting solar, relating to the field of solar energy, comprising a heat insulating layer, a heat collecting layer and heat conducting edge of said heat collecting layer is set with the heat preservation layer, the heat conducting and the insulating layer and the edge joint, the insulating layer comprises an upper transparent layer and a lower reflective layer, the heat collecting layer comprises the upper transparent layer and the lower reflecting layer of the graphene film. it can effectively seal the valve, ensuring the opening and closing mechanism of the valve is sealed tightly, improving the service life of the valve, reducing valve core force required for valve opening and closing can be made of flexible solar photothermal absorption film as the solar absorption conversion on the basis of the light heat conversion member can be bent and folded, it can realize water, antifreeze and wind.
