Description

High temperature secondary concentrating collector in a kind of solar energy with low-heat loss
Technical field
The utility model belongs in the solar energy elevated temperature heat and utilizes technical field, high temperature secondary concentrating collector in particularly a kind of solar energy with low heat waste.
Background technology
At present, generally the solar concentrator of Shi Yonging all is to be applied in the solar low-temperature field, mainly be to adopt vacuum tube or heat pipe as absorption tube, its structure design mainly is to accept source of parallel light in a side of concentrator or the light-receiving mouth on a plane of top design, designs simple relatively.Because of it is subjected to vacuum tube or the little restriction of heat pipe caliber, and the bigger influence of middle elevated temperature heat loss, the scope of application is very restricted.
The utility model content
The purpose of this utility model is the defective at above-mentioned prior art, and a kind of high temperature concentrating collector of accepting angle and ultralow heat loss greatly that has is provided.
The technical scheme taked of the utility model is to achieve these goals: high temperature secondary concentrating collector in a kind of solar energy with low heat waste, comprise absorption tube, described absorption tube is fixed in the internal reflection condenser by fixed support, described internal reflection condenser is arranged on the microscope base, be provided with the printing opacity form below the described microscope base, be provided with heat-insulation layer above the described microscope base, the minute surface of described internal reflection condenser is made up of parabola and two sections involute composite parabolics of forming along parabola of two sections symmetries.
Be provided with stay-warm case above the described heat-insulation layer.
Described microscope base inner surface and internal reflection condenser outer surface are tangent, and by flexible connection.
Described absorption tube is the plated film steel pipe, and external diameter is 60-100mm.
The material of described heat-insulation layer is for having the high-temperature resistant thermal insulating material of low thermal conductivity under the middle condition of high temperature.
Described printing opacity form is selected the safety glass of high transmission rate for use.
The beneficial effect that the utility model is implemented is: compared with prior art, the utility model heat collector has changed the structure of existing concentrator, the mirror curved surface of internal reflection condenser is by the parabola of two sections symmetries and two periods involute surface compound compositions, two sections paraboloidal focal lines drop on respectively on the plane of symmetry of high-temperature heat-collection pipe inside about its involute surface symmetry, because increased the design of two sections involute surfaces, so the light mouth that connects of concentrating collector has also increased width, thereby the optically focused ratio of concentrator and the receiving angle of light have been increased, can will incide the whole circumference of all light uniform convergences of sensitive surface, make the high temperature absorption tube can farthest accept the direct projection part and the dissipative part of light to the high temperature absorption tube.Structure has increased heat-insulation layer and printing opacity form, can intercept the inner Yin Gaowen of concentrator and the heat radiation and the thermal convection losses that cause.The utility model is with low cost, be easy to make, and light and heat collection effect height helps the utilization and extention of moderate-high temperature heat utilization systems in the solar energy.
