Abstract

The solar heat collector consists of casing, light incident port, spiral endothermic pipe and heat medium inlet and outlet. It is mounted over the disc parabolic mirror, and its light incident port is at the focus of parabolic mirror. The light ray incoming the endothermic cavity is multiple-reflected and the heat energy is absorbed by the endothermic pipe, which transfers heat energy to circular heat medium for efficient absorption.

Description

Disc focusing solar heat collector
The present invention relates to a kind of solar thermal collector of dish-type parabolic mirror focusing.
Present used dish-type parabolic minute surface focusing solar heat collector, general efficient is not high.Because the sunlight through dish-type parabolic minute surface is assembled concentrates on its focus, temperature is very high near the focus, and on general heat collector, the focus area occupied is very little, and heat-absorbent surface only can absorb a part of heat energy, and remaining heat energy will be reflected back toward in the atmosphere.From the principle Analysis of part heat absorption, this class heat collector collecting efficiency is low, is not easy to use.
The objective of the invention is to design a kind of solar thermal collector of dish-type parabolic mirror focusing.
Such heat collector is made up of thermal medium inlet, thermal medium outlet, spiral endothermic tube, housing and light inlet.Its housing is spherical in shape or barrel-shaped, and its front end has light inlet, and its inner surface plating reflective membrane is beneficial to reflection ray, reduces self heat absorption.Its spiral endothermic tube is arranged twist by endothermic tube, constitutes spherical or barrel-shaped heat-absorbing chamber, and processings of turning black of endothermic tube surface is beneficial to heat absorption, and its two ends export with thermal medium with the thermal medium inlet respectively and link to each other.Such heat collector is installed on dish-type parabolic minute surface top, paraboloidal focus is overlapped with light inlet, and the light that focuses on through parabola will all enter heat-absorbing chamber, and light is through repeatedly reflection in heat-absorbing chamber, the thermal medium that heat energy is circulated in the endothermic tube absorbs, and has improved the collecting efficiency of solar energy.
The invention has the advantages that: such solar thermal collector, can absorb solar energy continuously, endothermic process does not steadily have jumping phenomenon, the heat absorption efficiency height.In whole parts, nearly all be tube of material, assemble with welding method.Simple in structure, in light weight, be convenient to produce in enormous quantities and promote the use of.
