Abstract
The invention relates to a multitube heat collector with a solar energy focusing function, in particular to a high-temperature heat collector applicable to solar energy focusing of a slot type paraboloid. The multitube heat collector comprises a flange 1, a light inlet 2, an insulating layer 3, a sleeve pipe 4, heat absorbing tubes 5, a glass window 6 and the like. The multitube heat collector has the advantages that focused solar energy is reflected in the heat collector repeatedly after entering the heat collector, heat is absorbed repeatedly by the heat absorbing tubes, and heat media circulating in the heat absorbing tubes carry the heat out for utilization, so that solar energy heat collection efficiency is improved. The multitube heat collector with the solar energy focusing function is simple in structure and convenient to produce, mount and use.
Description
Technical field
The present invention relates to a kind of solar focusing multitube heat collector, be especially applicable to the high temperature heat collector of grooved parabola focused solar energy.
Background technology
The solar energy high temperature heat collector used at present, generally that the thermal-collecting tube with heat absorbing coating is installed on the paraboloidal focal line of grooved, because the solar energy energy-flux density that focal line focuses on is large, so the solar energy focused on impinges upon surfaces of collector tubes, have part solar energy reflection out, the general collecting efficiency of this heat collector is not high.
Summary of the invention
The object of the invention is to design a kind of solar focusing multitube heat collector, make the solar energy of focusing in heat collector cavity, multiple reflections and repeatedly being absorbed by endothermic tube, improve the solar focusing multitube heat collector of heat absorption efficiency.
The present invention includes flange 1, light inlet 2, heat insulation layer 3, sleeve pipe 4, endothermic tube 5 and glass window 6 etc.Sleeve pipe 4 is the pipe of opening, and its opening is light inlet 2, and there is glass window 6 outside of light inlet 2, with cleaning in retaining sleeve 4.There is heat insulation layer 3 outside of sleeve pipe 4, to reduce scattering and disappearing of solar heat.Have the endothermic tube 5 of annular spread in sleeve pipe 4, endothermic tube 5 Surface absorption solar energy, its inside is used for thermal medium circulation, and thermal medium takes the solar energy that endothermic tube 5 absorbs out of utilization.Sleeve pipe 4 and endothermic tube 5 are connected on flange 1, and flange 1 is for connecting heat medium circulation system and multiple heat collector.
This solar focusing multitube heat collector, be arranged on the focal line of grooved parabola focusing in use, and light inlet is aimed at focal line, the solar energy focused on enters heat collector by light inlet, solar energy is multiple reflections in heat collector, heat is absorbed repeatedly by endothermic tube, and the thermal medium of endothermic tube Inner eycle takes utilization out of heat.
The invention has the advantages that this solar focusing multitube heat collector, because after the solar energy focused on enters heat collector, multiple reflections in heat collector, heat is absorbed repeatedly by endothermic tube, the thermal medium of endothermic tube Inner eycle takes utilization out of heat, so improve solar energy heating efficiency.This solar focusing multitube collector structure is simple, is convenient to manufacture and install and use.
