Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated: as shown in Figure 1:
Close-coupled solar water heater, comprise incubator 6 and thermal-collecting tube 1, described incubator 6 comprises inner water tank 61, described thermal-collecting tube 1 comprises glass-vacuum tube 11, the cup-like structure that described glass-vacuum tube 11 forms for double glazing, glass-vacuum tube 11 one end are thermal-collecting tube blind end 14, and the other end is thermal-collecting tube openend 15; Glass-vacuum tube 11 comprises inner glass inner tube 12, space in glass inner tube 12 is media storage space 13, in described media storage space 13, be also provided with hard inner tube 2, described hard inner tube 2 is inner tube blind end 21 near one end of thermal-collecting tube blind end 14, the inner tube openend 25 that hard inner tube 2 other ends are hatch frame, in described hard inner tube 2, be provided with obturator 22, described obturator 22 Outside Dimensions are less than hard inner tube 2 inside dimensions, between described obturator 22 and hard inner tube 2, are provided with positioning element; Described water tank 61 bottoms are communicated with the inner tube openend 25 of at least one thermal-collecting tube 1.
Close-coupled solar water heater of the present utility model, comprise the incubator 6 on top and the thermal-collecting tube 1 of bottom, incubator 6 comprises inner water tank 61, water tank 61 is for storing heat transfer medium, so-called heat transfer medium refers to and absorbs sunshine heat, and heat is carried to the material of user side, for example water usually in solar water heater, or anti-icing fluid is as heat transfer medium.
Thermal-collecting tube 1 is by the heat absorption of sunshine and passes to the parts of inner heat transfer medium, and it comprises the obturator 22 in outside glass-vacuum tube 11, inner hard inner tube 2 and hard inner tube 2.
Hard inner tube 2 is arranged in the inner media storage space 13 forming of glass inner tube 12, glass inner tube 12 surface-coateds in glass-vacuum tube 11 have the absorbed layer 19 of selection, when water heater working, select absorbed layer 19 fully to absorb the heat of sunshine, and logical heat transfer raises the heat transfer medium temperature in hard inner tube 2, in hard inner tube 2, be provided with obturator 22, obturator 22 Outside Dimensions are less than hard inner tube 2 inside dimensions, heat transfer medium is entered after hard inner tube 2, be compressed in the small space between obturator 22 and hard inner tube 2.
This makes the sunshine heat that thermal-collecting tube absorbs be absorbed by heat transfer medium still less, thus heat transfer medium temperature can raise sooner, and form circulation.And because the high-temperature medium in thermal-collecting tube cannot arrive user side all the time, so the heat transfer medium of storing in thermal-collecting tube is fewer, the high-temperature medium of waste is just fewer, this is conducive to making full use of of high-temperature medium.
The positioning element arranging between described obturator 22 and hard inner tube 2 is in order to prevent that obturator 22 from shaking in hard inner tube 2.Hard inner tube 2 can be any have higher-strength and the good material of heat conduction, such as copper pipe, stainless steel tube, alumina ceramic tube etc.Obturator 22 can be solid construction, can be also hollow-core construction, and while adopting hollow-core construction, obturator 22 is interior can be vacuum state, also can be filled with inert gas, reduces its thermal conductivity.
