Solar heat collection device based on graphite film

Abstract

The invention discloses a solar heat collection device based on graphite film, and relates to the technical field of solar heat collectors. According to the solar heat collection device based on the graphite film, the graphite film with high thermal conductivity is adopted instead of a traditional heat absorber plate, the graphite film with high thermal conductivity makes direct contact with water, the thermal conduction efficiency is improved, the troublesome processing technology of a traditional heat absorber plate is omitted, the environmental pollution caused by spraying is avoided, and manpower, material resources and financial resources are greatly saved without a carrier of the traditional heat absorber plate. The solar heat collection device based on the graphite film particularlycomprises a base plate, a thermal insulation layer, a side plate, a liner and a transparent cover plate. A supporting rack is fixed to the base plate. The base plate and the side plate are fixedly connected to form a groove. The thermal insulation layer is arranged on the inner wall of the groove. The liner is fixed to the supporting rack. The graphite film with high thermal conductivity is arranged on the upward surface of the liner. The transparent cover plate is arranged on the graphite film with high thermal conductivity. The liner communicates with the exterior of the side plate througha water inlet pipe, a water outlet pipe and a drainage pipe.

Description

technical field [0001] The invention relates to the technical field of solar heat collectors, in particular to a solar heat collecting device based on a graphite film.
