Embodiment Construction

[0022] see figure 1 As shown, it is a structural schematic diagram of a Fresnel solar heat collector implementing the present invention. The Fresnel solar heat collector 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.

[0023] see figure 2 As shown, the receiver 11 is divided into several sections, and the absorbers of each section are connected by a transmission pipe 120 .

[0024] Please combine image 3 As shown, the structure of one section of the receiver will be described below, and the structure of the other sections of the receiver is the sam...

Abstract

The invention relates to a Fresnel solar collector which comprises a receiver and a light gathering module, wherein the light gathering module is provided with a plurality of reflecting mirrors used for reflecting sunlight to the receiver; the receiver is arranged above the light gathering module through a bracket and divided into a plurality of sections connected through transmission pipes; each section of the receiver comprises a series of mutually parallel extended heat absorption pipes; and both ends of each heat absorption pipe are connected with the transmission pipes at both ends of the receiver. Through the arrangement of the Fresnel solar collector, heat transmission fluid flowing out of the heat absorption pipe of each section of the receiver flows into the transmission pipes to be mixed for exchanging heat and then flows into the next section of the receiver to absorb heat so that the defect of non-uniform heating of the heat transmission fluid in the traditional receiver heat absorption pipes is overcome, thereby being more beneficial to improving the heat absorption efficiency.

Description

【Technical field】 [0001] The invention relates to a solar heat collector, in particular to a receiver of a Fresnel solar heat collector. 【Background technique】 [0002] The Fresnel solar collector mainly includes a linear Fresnel reflector (Linear FresnelReflector, LFR) system and a receiver, the linear Fresnel reflector system includes a linear reflector field, and the linear reflector field is composed of multiple It consists of two 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. For this related prior art, please refer to the PCT patent application with the publication number W...
