As shown in Figure 8, heat-transfer pipe 16 is equipped with between adjacent two thermal-collecting tubes 7, heat-transfer pipe 16 is connected with an outlet pipe 18 with a water inlet pipe 17 respectively, outlet pipe 18 communicates with an overflow pipe 19, the cooling water tank 20 of cold water is equipped with in overflow pipe 19 UNICOM one, overflow pipe 19 is also provided with one when outlet pipe 18 temperature is higher than the temperature control system 21 being communicated with outlet pipe 18 and cooling water tank 20 when 80 DEG C.As Fig. 9, shown in 10 and 11, temperature control system 21 comprises one and to be connected on overflow pipe 19 and tubular box body 211, the baffle plate 212 that the cavities seals in box body 211 is separated into cavity 1 and cavity 2 214 by one is installed with in box body 211, overflow pipe 19 is all connected with cavity 2 214 with cavity 1, baffle plate 212 center position is provided with a through hole 215, a valve 216 is inserted with in through hole 215, valve 216 is connected mutually with a push rod 217, push rod 217 other end is plugged in a sleeve 218, a Compress Spring 219 is provided with bottom sleeve 218 and between push rod 217 end, the packed layer 222 that fusing point is 80 DEG C is filled with in sleeve 218, box body 211 internal fixtion has supporting seat 223, and supporting seat 223 is in cavity 2 214, supporting seat 223 offers water hole 220.A sealing plate 221 is provided with between valve 216 and push rod 217, sealing plate 221 adopts elastomeric material to make, sealing plate 221 is fixed on push rod 217, valve 216 is fixed on sealing plate 221, and sealing plate 221 can be resisted against on baffle plate 212, sealing plate 221 is in order to valve 216 can better block through hole 215, improves reliability.
Specifically, packed layer 222 is lignite wax, and packed layer 222 accounts for 1/3rd of the cavity volume formed between push rod 217 end and sleeve 218 inwall when Compress Spring 219 is in impaction state.Lignite wax is a kind of containing wax, resin and asphaltic mineral wax, and fusing point is approximately 80 DEG C, and when temperature in outlet pipe 18 is lower than 80 DEG C, Compress Spring 219 solidifies by lignite wax, and Compress Spring 219 can not be recovered, and then can not by hydraulic pressure force compression; When temperature in outlet pipe 18 reaches lignite wax 80 DEG C, lignite wax softens and melts, valve 216 promotes push rod 217 Open valve 216 by hydraulic pressure effect, enables the high-temperature water in outlet pipe 18 enter in cooling water tank 20 rapidly, is lowered the temperature by tap moisturizing to the water in outlet pipe 18.Box body 211 is horizontally fixed on overflow pipe 19, expands after lignite wax is heated, so lignite wax can not fill up sleeve 218 inner chamber, but by horizontal positioned box body 211, Compress Spring 219 is solidified by lignite wax preferably, valve 216 can not be opened by mistake and open.Valve 216 is by Compress Spring 219 to be pressed on baffle plate 212 and to be blocked by through hole 215 tightly, can slide in sleeve 218 at the effect lower push-rod 217 of the restoring force of Compress Spring 219, when temperature is higher than 80 DEG C, originally the packed layer 222 be under solid state discharges Compress Spring 219, Compress Spring 219 can be extruded by hydraulic pressure, thus open valve 216, after valve 216 is unlocked, high-temperature water in outlet pipe 18 can enter in cooling water tank 20, for user by overflow pipe 19, through hole 215 and water hole 220.
The water inlet of water inlet pipe 17 is connected with a tap, tap of fetching boiling water just can make cold water flow in heat-transfer pipe 16, heat-transfer pipe 16 absorbs solar energy and heats the water in heat-transfer pipe 16, water is by water inlet pipe 17 under normal circumstances, heat-transfer pipe 16 and outlet pipe 18 circulate, solar energy is absorbed for a long time through heat-transfer pipe 16, water inlet pipe 17, water in heat-transfer pipe 16 and outlet pipe 18 heats up, when the temperature of water is higher than 80 DEG C, temperature control system 21 is communicated with outlet pipe 18 and cooling water tank 20, the high-temperature water in outlet pipe 18 is made to flow in cooling water tank 20, in water inlet pipe 17, pressure reduces, tap carries out moisturizing to water inlet pipe 17 automatically, thus the temperature in outlet pipe 18 is reduced, not only heat-transfer pipe 16 is played to the effect of protection, and the inconvenience that the water in cooling water tank 20 also can avoid water temperature over-high to bring user.
Installing frame 2 is in rectangular-shaped, and comprise the cavity 3d that can install thermal-collecting tube 7, the top of installing frame 2 offers the opening that can be connected with cavity 3d, and the bottom of installing frame 2 is fixed with the base plate 15 that cavity 3d can be sealed up.Reflector plate 11 and thermal-collecting tube 7 can be installed in the cavity 3d of installing frame 2 easily by the opening on installing frame 2, and reflector plate 11 is arranged between thermal-collecting tube 7 and base plate 15, reflector plate 11 just can be prevented to be moved, affect reflecting effect.Installing frame 2 is fixed with the glass 14 that opening can be sealed up, glass 14 is fixed on installing frame 2 by glass cement, and this glass 14 can protect thermal-collecting tube 7 can not be subject to the interference of foreign material, keeps clean, ensures the absorption efficiency of thermal-collecting tube 7 pairs of sunshines.
Support 1 comprises montant one, montant two, cross bar one, cross bar two and connecting rod, material is temperature zine plate, one end of montant one is fixed on the top of installing frame 2, and the other end of montant one and one end of cross bar one are fixed, and the other end of cross bar one is fixed on the bottom of installing frame 2; One end of montant two is fixed on the top of installing frame 2, and the other end of montant two and one end of cross bar two are fixed, and the other end of cross bar two is fixed on the bottom of installing frame 2; One end of connecting rod is fixed on the junction of montant one and cross bar one, and the other end of connecting rod is fixed on the junction of montant two and cross bar two.So support 1 can form triangle with installing frame 2 and fix, fixing-stable, and, reasonably can arrange in pairs or groups with various installation environment to this mounting bracket 1, to adapt to various different installation environment, the collector array being arbitrarily made with all size collector area can be adapted to simultaneously.
Water in header 3 can heat by this structure improved solar thermal collector, and heat production efficiency is high.On June 1st, 2013, through Zhejiang, Shen De new forms of energy Co., Ltd made experiment, for thermal-collecting tube 7 specification of specifying and quantity, measured following data, as following table:
The operation principle of this structure improved solar thermal collector is so, this structure improved solar thermal collector is placed under the sun-drenched sun, sunlight is on the outer tube body hypomere 72b of thermal-collecting tube 7, under the effect of thermal-arrest film plating layer 8, the interior tube body hypomere 72a of thermal-collecting tube 7 absorbs solar energy and is translated into heat energy, superconducting fluid in heating interior tube body hypomere 72a is also vaporized, superconducting fluid after gasification will the elegant interior tube body epimere 71a to thermal-collecting tube 7, because the outer tube body epimere 71b of thermal-collecting tube 7 is set in heat exchange jacket 6, and outer tube body epimere 71b is close on the inwall of heat exchange jacket 6, this just can make heat exchange jacket 6 generate heat, by heat exchange jacket 6 thus the water transferred heat in inner bag 3b, water is heated, because thermal-collecting tube 7 is separated with inner bag 3b by heat exchange jacket 6, every root thermal-collecting tube 7 all works alone, this just can make the remaining thermal-collecting tube 7 when many thermal-collecting tubes 7 break or lost efficacy still can continue heating to the water in inner bag 3b.
