The specific embodiment
Below in conjunction with specific embodiment the utility model is further set forth.
As Fig. 1, Fig. 2 and shown in Figure 3, the solar water heater that the utility model provides, mainly comprise: all-glass vacuum thermal-collecting tube 1 and storage tank, described storage tank comprise storage tank shell 2, heat-insulation layer 3, sandwich gall 4, inner bag 5, header 6, union pipe 7 and 8, pressure release jar 9 and liquid injection port 10 up and down.Fig. 2 is each parts connection diagram of the utility model solar water heater, Fig. 3 is the overall schematic of the utility model solar water heater, and Fig. 2 and Fig. 3 are solar water heater of the present utility model and the perpendicular profile of solar water heater section shown in Figure 1.As shown in Figures 2 and 3, solar water heater of the present utility model also comprises cold water inlet 11 and hot water outlet 12.
Wherein, inner bag 5 is nested in the sandwich gall 4,5 skins of setting, and inner bag with one heart fit tightly with sandwich gall 4 internal layers, and sandwich gall 4 skins are closely fitted with heat-insulation layer 3 and storage tank shell 2 successively.Pressure release jar 9 is arranged on water heater top, and the one end passes storage tank shell 2 and heat-insulation layer 3 is connected on the sandwich gall 4.The both sides that header 6 is relative are up and down passed through up and down respectively, and union pipe 7,8 is connected with sandwich gall 4, all-glass vacuum thermal-collecting tube 1 is inserted in the header 6, thereby with sandwich gall 4 by header 6 and peripheral passage of union pipe 7,8 formation up and down, liquid injection port 10 is arranged on water heater bottom, pass storage tank shell 2 links to each other with sandwich gall 4 with heat-insulation layer 3, heat transferring medium enters into sandwich gall 4 by liquid injection port 10, and can be at vacuum heat collection pipe 1 and sandwich gall 4 by header 6 with circulate in union pipe 7,8 these peripheral passages of formation up and down.Cold water inlet 11 that links to each other with inner bag 5 and hot water outlet 12 can be arranged on the water heater below.
The operation principle of the solar water heater that the utility model provides is: cold water enters into inner bag 5 by cold water inlet 11, heat transferring medium enters into sandwich gall 4 by liquid injection port 10, and can via header 6 and up and down union pipe 7,8 enter into all-glass vacuum thermal-collecting tube 1.When solar irradiation was mapped on the all-glass vacuum thermal-collecting tube 1, luminous energy was converted into thermal energy transfer to the heat transferring medium in the all-glass vacuum thermal-collecting tube 1.Because the thermal siphon phenomenon, the heat transferring medium of heat is operation upwards, enters in the sandwich gall 4 by header 6 and last union pipe 7, makes heat transferring medium move to form along sandwich gall 4 simultaneously and circulates.The inwall of the inner bag 5 of the heat transferring medium of heat by being nested in sandwich gall 4 inner close fitting sandwich galls 4, with the water in the heat transferred inner bag 5, by heat exchange, the temperature of water can rise, and the temperature of heat transferring medium will descend, the heat transferring medium that temperature reduces after heat exchange moves along the media flow direction, moves under the side direction away from vacuum tube, and union pipe 8 and header 6 return and flow to the heat that absorbs sunshine in the all-glass vacuum thermal-collecting tube 1 once more under the warp.Like this, heat transferring medium via header 6 and up and down union pipe 7,8 between all-glass vacuum thermal-collecting tube 1 and sandwich gall 4, circulate, with inner bag 5 in water carry out heat exchange, continuous and so forth.Meanwhile, the pressure of the heat transferring medium in 9 pairs of all-glass vacuum thermal-collecting tubes 1 of pressure release jar and the sandwich gall 4 is regulated.
Wherein, the solar water heater that the utility model provides, described inner bag 5 adopts the hot rolled steel plate welding, and the thickness of hot rolled steel plate is 1.0-2.5mm, wherein preferred 1.8mm, its inwall enamel, more traditional like this stainless steel inner container, antiseptic effect is better, and the life-span is longer; Described sandwich gall 4 adopts hot rolled steel plate, and the thickness of this hot rolled steel plate is 0.8-2.0mm, wherein preferred 1.5mm.Can also between inner bag 5 and sandwich gall 4, add corrosion inhibiter, thereby further reach antiseptic effect.
In addition, the solar water heater that the utility model provides, also can between the heat-insulation layer 3 of above-mentioned solar water heater and sandwich gall 4, set up one deck thermal reflecting coating, when the water of heat transferring medium in inner bag 5 of heat in the sandwich gall 4 transmits heat, also can outwards distribute by some heat, this moment, thermal reflecting coating returned the reflect heat of distributing to sandwich gall 4, reduced the thermal losses of the heat transferring medium of heat like this, further strengthened heat exchange efficiency, energy savings, can strengthen heat insulation effect simultaneously.
In addition, as shown in Figure 2, the last union pipe 7 that connects sandwich gall 4 and header 6 also can be set to many, same, the quantity that union pipe 8 is set down is corresponding with it, increase the flowing space of heat transferring medium and, more help heat transferring medium flowing between sandwich gall 4 and all-glass vacuum thermal-collecting tube 1, carry out heat exchange further to be beneficial to fluid space.And described union pipe 7,8 up and down can adopt bellows to realize.
Moreover, header 6 can be a rectangle, square, oval, also can be other Any shape that are complementary with sandwich gall 4 arcs, can be the falcate consistent with sandwich gall as radian.Union pipe 7,8 can be weldingly connected with header 6 respectively and connect up and down, also can be that union pipe 7,8 and header 6 are integral.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
