Problems solved by technology

However, since the sunlight irradiating the heat absorber is the sunlight focused by the reflector, the heat-absorbing coil located at the bottom of the heat-absorbing cavity (especially the heat-absorbing coil located in the middle of the bottom) receives more heat, easy to burn

Embodiment Construction

[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] The distribution law of the heat flux density in the heat absorption cavity of the concentrating solar heat absorber is as follows: the heat flux density is the highest in the middle and gradually decreases along the radial direction. Therefore, the heat-absorbing coil located in the middle of the heat-absorbing cavity is easily burnt out because it is heated a lot. To this end, the present invention discloses a novel focused s...

Abstract

A W-type concentrating solar heat absorber, comprising: an outer casing (1), a heat-absorbing chamber (2), and heat-absorbing coils (3) attached to a side wall of the heat-absorbing chamber (2). The bottom of the heat-absorbing chamber (2) of the heat absorber is provided with a reflecting device (4) used for evenly reflecting sunlight shining on the bottom of the heat-absorbing chamber (2) onto the side wall of the heat-absorbing chamber (2), thereby ensuring solar energy utilization, and preventing heat-absorbing coils (3) located at the bottom of the heat-absorbing chamber (2) from being burnt due to overheating.

Description

technical field [0001] The invention relates to the field of solar energy application, and more particularly to a W-type concentrating solar heat absorber. Background technique [0002] Due to the shortage of conventional energy and the pollution caused by conventional energy, solar energy, as a pollution-free and infinitely usable resource, has been paid attention to by countries all over the world. [0003] At present, people have carried out in-depth research on the utilization of solar energy in various technical fields, such as: solar power stations, solar high-temperature furnaces and so on. In any solar energy application, solar heat absorbers are required to collect solar energy and convert it into heat energy. [0004] In order to improve the utilization rate of solar energy, the heat absorption coils of the current heat absorber are evenly distributed in the entire heat absorption cavity to absorb all the solar energy irradiated into the heat absorption cavity as ...
