Solar heat collector

Abstract

The invention discloses a solar heat collector and relates to the technical field of transformation from solar energy into heat energy. The solar heat collector consists of a bracket, a V-shaped corrugated light reflecting plate, a solar vacuum heat collecting tube, a heated core, a central connection box and another solar vacuum heat collecting tube in a fixation manner; each solar vacuum heat collecting tube is a double-layer heterogeneous vacuum tubular component and consists of an outer layer glass tube, an inner layer oxygen-free copper tube, a selective heat absorbing material layer, a vacuum sealing device, a drying agent, a moisture absorption membrane and a positioning plate, wherein the selective heat absorbing material layer is attached to the outer wall of the inner layer oxygen-free copper tube; the heated core is a U-shaped hollow copper tube of which the section is annular and consists of a water feeding tube, a heated core body, a water discharging pipe and an expansionspring; and the central connection box is a rectangular box body which consists of an upper box body and a lower box body which are combined with each other in a buckling manner. The solar heat collector has the advantages of reasonable structure, short and quick temperature increment, high photo-thermal transformation efficiency and the like.

Description

technical field [0001] The invention relates to the technical field of solar energy, in particular to a solar heat collector. Background technique [0002] At present, with the continuous progress of science and technology, new materials and new technologies are changing rapidly in my country's solar heat collection technology, which has cultivated and spawned batches of new equipment, and also provides solid technical support for the application of this technology. The world is moving and developing, and any new thing has a process of growth and progress. The same is true for the existing solar heat collection technology. With the continuous deepening of popularization and application, some deep-seated problems have gradually surfaced, such as the problem of large heat dissipation loss of planar solar collectors, U-shaped solar collectors, and the efficiency of photothermal conversion. Low, the problem of large lighting area. Another example is glass-metal solar collector...
