Medium-temperature wide-breadth solar heat collecting device

Abstract

The invention belongs to the technical field of utilization of solar heat and particularly relates to a medium-temperature wide-breadth solar heat collecting device. The medium-temperature wide-breadth solar heat collecting device comprises at least one independent heat absorber, an outer frame, a heat insulating material, a base plate, a transparent cover plate and a cellular board, wherein the independent heat absorbers are connected in series to form a heat collecting component which has a required size; the base plate and the outer frame are assembled to form a box-like space; the heat insulating material is arranged inside the box-like space; each heat absorber is fixedly arranged on the outer frame; the cellular board and the transparent cover plate are arranged above the heat absorbers. In the medium-temperature wide-breadth solar heat collecting device disclosed by the embodiment of the invention, at least one or more independent heat absorbers are connected in series to form the heat collecting component which has the required size; the area of a heat collector is as large as 10 to 36 square meters; the heat collector can be used for replacing components such as a building roof, a wall body, a curtain wall, a parapet wall and the like and breaks through the limitation that the heat collector can only be additionally mounted on a roof or a wall body.

Description

technical field [0001] The invention belongs to the technical field of solar thermal utilization, and in particular relates to a medium-temperature and wide-format solar heat collecting device. Background technique [0002] For flat-panel solar collectors, domestically and internationally, they are usually arranged and installed on buildings in units of small surfaces (for example, the ratio of length to width is 2x1), and they are connected in series and parallel to form a certain area of ​​collector display. However, the disadvantage of this structure is that the heat collector wastes the limited light area on the building due to the gap between them; it hinders the fluidity of the heat carrier and reduces the thermal efficiency of the heat collector; its transparent cover is basically Single-layer tempered glass or even float glass is used, so that the heat collected by the collector is largely wasted; the temperature of hot water is limited to below 60 ℃, it is difficult...
