Embodiment Construction

[0006] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0007] Such as figure 1 The illustrated embodiment includes a paraboloid, a parabolic support, a support frame, a shaft plate, a heat collector support, a heat collector connection plate, a heat insulation layer of a heat collector, an outer cavity of a heat collector, an inner cavity of a heat collector, and a heat collector. light inlet, etc. The paraboloid is a trough-shaped paraboloid, and its surface is coated with reflective film to facilitate the reflection of sunlight. The paraboloid is a truncated paraboloid to reduce wind resistance. The paraboloid is installed on the paraboloid support. The other end is connected to the shaft plate, the shaft plate is connected to the sun tracking system, one end of the collector bracket is connected to the support frame, the other end of the collector bracket is connected to the collector connecti...

Abstract

The invention relates to a cavity-type solar collector, in particular to a solar collector suitable for focusing with a trough-type paraboloid. The cavity-type solar collector comprises a paraboloid 1, a parabolic bracket 2, a supporting frame 3, a hub disk 4, a collector bracket 5, a collector connection plate 6, a collector heat insulation layer 7, a collector outer cavity 8, a collector inner cavity 9, a collector light incidence port 10 and the like. The paraboloid 1 is a trough-type paraboloid of which the surface is plated with a reflective membrane; the collector inner cavity 9 and thecollector outer cavity 8 are tubular and the cross sections thereof are open ellipses, open polygons or combinations of the open ellipses and the open polygons; the collector inner cavity 9 and the collector outer cavity 8 form an annular space; the surface of the collector inner cavity 9 is blackened; and the collector light incidence port 10 is positioned on a focal line of the paraboloid 1. Thecavity-type solar collector has the advantages that: when the cavity-type solar collector is used, focused sunlight enters into the collector inner cavity through the collector light incidence port and is reflected many times in the collector inner cavity to allow the solar energy to be adsorbed repeatedly by the collector inner cavity, so the heat collecting efficiency of the solar energy is improved.

Description

technical field [0001] The invention relates to a cavity-type solar heat collector, in particular to a solar heat collector suitable for focusing on a trough-shaped parabolic surface. Background technique [0002] The trough parabolic solar collectors currently used are generally tubular, and the tubular collector is located at the focal line of the trough paraboloid. The focused sunlight shines on the surface of the tubular collector. Due to the focused solar energy flow The density is very high, and the tubular heat collector cannot completely absorb it, and the rest of the energy flow is reflected, so the heat collection efficiency is low. Contents of the invention [0003] The present invention includes a parabolic surface 1, a parabolic surface support 2, a support frame 3, a shaft plate 4, a heat collector support 5, a heat collector connection plate 6, a heat collector insulation layer 7, a heat collector outer cavity 8, and a heat collector inner cavity. Cavity 9 ...
