Figure 2 shows that the schematic diagram of the solar thermal collector that the decalescence that hot pipe type vacuum endothermic tube is installed on both sides is combined with heat pipe.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
The schematic diagram of the solar thermal collector that decalescence of the present invention is combined with heat pipe as depicted in figs. 1 and 2, comprise many hot pipe type vacuum endothermic tubes 5, main header 8, tail header 6, phase-changing energy-storing case 2 and refrigerant endothermic tube 3, many hot pipe type vacuum endothermic tubes 5 can be positioned at the same side, its schematic diagram as shown in Figure 1, also can arrange in both sides, its schematic diagram as shown in Figure 2.Described hot pipe type vacuum endothermic tube 5 comprises canals of stilling and the heat pipe of vacuum, and the evaporator section of described heat pipe is installed on described canals of stilling inside, and the condensation segment 4 of described heat pipe is placed in described canals of stilling outside.In described main header 8, phase-changing energy-storing case 2 is installed, in described phase-changing energy-storing case 2, is filled with energy storage materials of phase change.Described main header 8 outer setting has heat-insulation layer 1.The condensation segment 4 of many described heat pipes to be placed in described phase-changing energy-storing case 2 and coated by described energy storage materials of phase change, and the heat of described heat pipe condenser section 4 is imported in described energy storage materials of phase change by heat-conducting silicone grease 7.The other end of described hot pipe type vacuum endothermic tube is linked into an integrated entity by described tail header 6.Described refrigerant endothermic tube 3 is placed in the energy storage materials of phase change of described phase-changing energy-storing case 2, and the refrigerant inlet that the two ends of described refrigerant endothermic tube 3 are connected to through described phase-changing energy-storing case 2 and main header 8 is taken over and refrigerant exit adapter.
In order to heat-conducting effect is better, described refrigerant endothermic tube 3 is provided with heat transmission fin.Described refrigerant endothermic tube 3 is the metal material that thermal conductivity is strong, is preferably copper pipe.
Described energy storage materials of phase change is stearic acid, three tristearin, paraffin, sodium sulphate, calcium chloride, magnesium chloride etc. and hydrate thereof.
Described heat-insulation layer is pvc material.
Wherein, refrigerant endothermic tube can be water pipe, airduct etc. according to the difference in the field of use.When solar thermal collector of the present invention is used for hot-water heating system, refrigerant is water, and refrigerant endothermic tube is water pipe.When for direct heating wind system or add other heat transmission equipment carry out heat exchange time, refrigerant is air, and refrigerant endothermic tube is airduct.The form of its airduct can be a thicker pipeline, may also be several with the little pipeline of caliber.
On the daytime having illumination, the evaporator section in hot pipe type vacuum endothermic tube absorbs the heat storage of solar energy in the energy storage materials of phase change of phase-changing energy-storing case.During use, refrigerant flows into from refrigerant inlet adapter, the heat comparing energy-accumulation material storage is taken away, directly refrigerant is heated in phase-changing energy-storing case 2, flows out from refrigerant exit adapter, is directly supplied to user and uses.If use system by day, the part heat that refrigerant endothermic tube absorbs directly can also pass to refrigerant, and improve the efficiency of heat pipe, the heat that whole system is obtained also increases to some extent.When system does not use, the heat that heat pipe type vacuum pipe absorbs just can well be accumulated in phase-changing energy-storing case, especially when continuous several days solar energy deficiencies, can ensure the continuous use of solar thermal collector.The solar thermal collector of decalescence of the present invention and heat pipe associative form it can accumulation of heat under the continuous several days sun are not good situations, substantially can ensure there is very high temperature in phase-changing energy-storing case, thus expand the scope of application.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
