Embodiment Construction

[0020] 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.

[0021] Please combine figure 2 As shown, the receiver 11 includes a housing 110. In practice, the outer surface of the housing 110 is streamlined (such as semicircular or elliptical), thereby reducing air resistance, and the housing 110 is provided with a A series of heat-absorbing tubes 113 extending parallel to each...

Abstract

The invention relates to a linear Fresnel solar heat collector which comprises a receiver and a light condensing module. The light condensing module is provided with a plurality of reflecting mirrors for reflecting sunlight to the receiver; the receiver comprises a series of heat absorption tubes extending in parallel and is arranged above the light condensing module through a support frame; the heat absorption tubes jointly form a cavity; an opening is formed at one end of the cavity facing to the light condensing module; the sunlight condensed from the light condensing module enters the cavity from the opening through the arrangement and is reflected for more times in the cavity, thereby achieving the highly-efficient absorption; and meanwhile, insulating materials are also arranged outside the cavity, thereby effectively reducing the convection heat loss. In addition, the invention not only can reduce the convection loss, but also can reduce the heat loss caused by black body radiation and simultaneously can reduce the cost through the design of the cavity.

Description

【Technical field】 [0001] The invention relates to a solar heat collector, in particular to 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 WO2009 / 023063...
