Embodiment Construction

[0018] see figure 1 As shown, it is a schematic structural diagram of a linear Fresnel solar collector device implementing the present invention. The linear Fresnel solar collector device 1 includes a light concentrating module 10 and a receiver 11 . Wherein the light concentrating module 10 is provided with a plurality of strip reflectors 100, and the light concentrating module 10 is also provided with a sun tracking structure (not shown), and the sun tracking structure rotates the reflector 100 to track the movement of the sun so as to maintain focus , the sun tracking structure has been described in the prior art, and will not be described in detail here.

[0019] Please combine figure 2 As shown, the receiver 11 includes a sealing cover 110. In practice, the outer surface of the sealing cover 110 is streamlined (such as semicircle or ellipse), thereby reducing air resistance, and the sealing cover 110 is provided with a series of heat-absorbing tubes 113 extending paral...

Abstract

The invention relates to a linear Fresnel solar heat collector device comprising a receiver and an optical concentration module, wherein the optical concentration module is used for reflecting sunlight to the receiver, and the receiver is arranged above the optical concentration module by a bracket. The receiver comprises a series of heat absorption pipes which mutually extend in parallel, the heat absorption pipes form a cavity body together, an opening is arranged at one end of the cavity body facing to the optical concentration module, the outside of the opening is covered by a transparent cover body, a sealing cover body is arranged at one end of the receiver which is far away from the opening, a vacuum chamber is formed between the transparent cover body and the sealing cover body, the heat absorption pipes are contained in the vacuum chamber, and the sunlight focused by the optical concentration module enters the cavity body from the opening, is reflected for many times in the cavity body and is absorbed. Meanwhile, vacuum is arranged between the transparent cover body and the sealing cover body, so that the convection heat loss can be effectively reduced, and the heat absorption efficiency of the receiver is enhanced.

Description

【Technical field】 [0001] The invention relates to a solar heat collector, in particular to a receiver of a linear Fresnel solar heat collector device. 【Background technique】 [0002] The linear Fresnel solar collector device mainly includes a linear Fresnel reflector (Linear Fresnel Reflector, LFR) system and a receiver, the linear Fresnel reflector system includes a linear reflector field, and the linear reflector field It consists of multiple reflectors arranged side by side in parallel, and these reflectors can be driven by a tracking device to track the movement of the sun. The sunlight reflected by these reflectors is concentrated into a receiver arranged above the reflectors, through which the solar energy is converted into heat energy. Usually one receiver can be arranged between a plurality of reflectors, so as to receive the sunlight reflected by the plurality of reflectors. This related prior art can refer to the PCT patent application with the publication number...
