Abstract
The invention provides a solar heat collector, which comprises an installing support frame and is characterized in that a group of U-shaped pipes in end-to-end connection is arranged on the installing support frame, a lens cover case is arranged on a straight pipe of each U-shaped pipe, the cross section of the lens cover case is in a semicircular shape, and the two ends of each U-shaped pipe are respectively connected with a water supply box and a water storage box. The solar heat collector has the advantages that the lens cover case is arranged on the straight pipe part of each U-shaped pipe, the incident sun light is focused by the lens and is then irradiated onto the U-shaped pipe, the illumination intensity of the sun light is improved, and the heat conversion efficiency is high.
Description
technical field:
The present invention relates to a kind of solar thermal collector, belong to technical field of solar utilization technique.
background technology:
In solar energy heating utilization, key is that the radiant energy of the sun is converted to heat energy.Because solar energy compares dispersion, it must be managed to put together, so heat collector is the various key components utilizing solar energy equipment.Flat-plate solar collector is the basic element of character of solar low-temperature heat utilization, is also the leading products of world solar markets always.Flat plate collector has been widely used in the numerous areas such as domestic water heating, natatorium heating system, water for industrial use heating, constructure heating and air-conditioning.With water heater and the flat plate solar water heater of flat-plate solar collector parts composition.
Existing flat-plate solar collector is primarily of a few part composition such as flat-plate solar collector absorber plate, transparent cover plate of flat plate solar heat collector, flat-plate solar collector thermal insulation layer and panel solar heat collector shell, sunlight is irradiated to surface through transparent cover plate and scribbles on the absorber of absorbed layer, wherein most of solar radiant energy is absorbed by absorber, change heat energy into, and be transmitted to the working medium in fluid passage.Like this, from the cold working medium of heat collector bottom inlet, in the fluid passage heat by solar energy, temperature raises gradually, the hot working fluid after heating, with the upper end outlet of useful heat energy from heat collector, stores in water storage tank stand-by, is useful energy income.Meanwhile, because absorber temperature raises, by transparent cover plate and shell to environment dissipated heat, the various heat loss of flat plate collector are formed.Because heat absorption efficiency is low and heat loss is high, cause the solar energy utilization ratio of current flat-plate solar heat collector not high, the efficiency of utilization improving plate type solar becomes problem in the urgent need to address at present.
summary of the invention:
The object of the invention is to provide a kind of solar thermal collector for above-mentioned Problems existing, effectively can improve the absorptivity of solar energy, reduce heat loss simultaneously, more wide approach is opened up in the application for flat-plate solar collector.
Above-mentioned object is realized by following technical scheme:
Solar thermal collector, comprise mounting bracket, described mounting bracket is installed one group of end to end U-tube, mounted lens case on the straight tube of each described U-tube, the cross section semicircular in shape of described lens case, the two ends of described U-tube connect supply tank and storage tank respectively.
