Embodiment 1

[0015] see figure 1 , this embodiment is a curved-plane concentrator, that is, the horizontal concentrator adopts a curved form, and the vertical concentrator adopts a planar form. It consists of a heat absorbing body 1, a vertical focusing disc 2, a horizontal focusing disc 3, a mold base 4 and connectors. The best solution for heat absorbing body 1 is to use a heat collecting box with glass on both sides and an insulating layer on the frame; the plate core is made in the form of a flat plate collector; Type focusing disc 3 is consistent, its height is one time of horizontal focusing disc 3 heights, and width gets 8cm. The mold base 4 is to determine the model support of the translational paraboloid of the horizontal focusing disc 3, and the horizontal focusing disc 3 is equipped with two mold bases before and after. Formwork 4 is made with reference to several points of the parabola, and the reference parabola is x 2 =100y, get the line segment below its focal plane as th...

Embodiment 2

[0017] Referring to Fig. 2, this embodiment is a hyperboloid concentrator, that is, both the horizontal concentrator and the vertical concentrator are curved. It is also composed of a heat absorber, a vertical concentrator, a horizontal concentrator, a mold base and connectors. The manufacturing method and structure are the same as those in the embodiment. In order to increase the heat collection effect, its vertical concentrator adopts a translational parabolic surface structure, and the lower part of the vertical concentrator is processed into a curve corresponding to that of the horizontal concentrator. The two concentrators are connected by a triangular joint.

Abstract

The 3D solar light focusing and heat collecting apparatus includes support frame, sunlight reflecting condenser, light spot receiving heat absorber. The sunlight reflecting condenser includes at least two parts, the horizontal condenser with north-south axis and the vertical condenser connected to the north end of the horizontal condenser. The double-panel heat absorber is set in the center of the horizontal condenser perpendicularly and has its north end connected to the vertical condenser perpendicularly. The said fixed structure can solve the problem of light focusing and heat collecting to the moving sun. The present invention has simple structure, low cost, high heat collecting efficiency and other advantages.

Description

technical field [0001] The invention relates to solar thermal energy utilization technology, especially a solar heat collector. Background technique [0002] The heat utilization of solar energy is mainly about the problem of heat collection technology. At present, there are three main methods of solar heat collection: flat plate collectors, vacuum tubes and tracking concentrating collectors. The flat plate collector is a simple heat collection method, but its heat collection effect is relatively poor. The vacuum tube is a double-layer vacuum glass tube. Its process is relatively complicated, and it is easy to damage glass products. Similar to the present invention is the tracking concentrating heat collector. The tracking concentrating collector uses a curved surface concentrator to gather sunlight into high-density light spots, and then receives the light spots through the heat absorbing body tube. At the same time, a tracking system is equipped to track the sun at all t...
