The ultrathin solar water heater of double-vacuum glass plate
Technical field
The utility model: relate to the ultrathin solar water heater of a kind of double-vacuum glass plate.
Background technology
Present domestic solar water heater great majority are the glass tube with vacuum solar water heater, and this product is because of water-filling in the glass tube with vacuum, receive after the solar radiation general temperature arrive more than 65 ℃ can fouling, incrustation scale can intercept thermal energy transfer, and the thermal efficiency is reduced.The glass tube with vacuum water-filling can freeze in the winter of severe cold, and volumetric expansion makes the vacuum glass pipe explosion, one be out of order by all means the back complete equipment all can not work.The glass tube with vacuum solar water heater is that volume is bigger, and there is cyclic water tank on top and relatively difficulty is installed, and hot and cold water flows in same glass tube with vacuum when its work, and hot water makes progress away, and cold water is walked downwards, can produce backheat and infiltration, and the thermal efficiency is reduced.
Summary of the invention
The utility model is released the ultrathin solar water heater of a kind of double-vacuum glass plate, it is characterized in that having adopted two vacuum glass 1 and 2, install in the middle of the two inner frame 3, absorber plate 4, in fill ethylene glycol solution 5 as working medium, inner frame periphery painting water-proof adhesive 6, it adds insulation material 7, backbone block 8, outside framework 9, inner frame 3, inner chamber forms the circulatory system by the heat exchanger in the pipeline water storage tank 16 12, and ethylene glycol solution flows therein and makes the thermal energy transfer in the inner frame 3 give the cold water of water storage tank 16 and it is heated up to reach serviceable condition.The utility model is by two hollow plate glass therebetween inner frames and absorber plate, fill ethylene glycol solution in the middle of the inner frame, and by heat exchanger formation heat circulation system in pipeline and the water storage tank, ethylene glycol solution flows therein and makes in the inner frame thermal energy transfer give the cold water of water storage tank and make its intensification, to reach operable state.Characteristics of the present utility model are that the hollow plate glass light transmission is good, sunshine sees through hollow plate glass and is radiated and emits heat on the absorber plate and absorbed by absorber plate, ethylene glycol solution flows in its circulatory system, with absorber plate in the inner frame and solution, the heat that hollow plate glass absorbs is delivered to heat exchanger, can intercept heat energy simultaneously again and run off.Hollow plate glass is 8 times of monolithic glass obstructing capacity.This product is by the ethylene glycol solution transferring heat energy, the solar energy transmission is fed water, make it not contact hollow plate glass, so can not freeze, stop dangerous also can the bearing of explosion and directly drawn the pressure that running water enters water in the water storage tank, non-scaling can make the hollow plate glass surface keep clean, and reduces heat-energy losses.

The specific embodiment
The utility model be have in the middle of two hollow plate glass inner frame, absorber plate, in fill the heat-transfer working medium ethylene glycol solution.Be connected to form the circulatory system by pipeline and heat exchanger in the middle of the inner frame, solution flows within it solar energy is passed to heat exchanger, and by tube wall thermal energy transfer is fed water, and reaches practical purpose.The utility model initial vacuum glass plate light transmission is good, and the front and back hollow plate glass all had the effect that intercepts heat energy dissipation when absorber plate absorbed solar energy.In inner frame, fill the working medium ethylene glycol solution, form working medium flow circuit system by pipeline and heat exchanger, working medium enters the inner frame chamber from the feed liquor tube head, cause its temperature to rise solar absorption when running into absorber plate, through fluid tube head, drain pipe, heat exchanger feed liquor tube head, enter heat exchanger, by tube wall the water in the water storage tank is heated, working medium is lowered the temperature and is flowed downward after overheated conduction, enters by way of heat exchanger fluid tube head, feed tube, feed liquor tube head and finishes once circulation in the inner frame chamber.This process continuously circulates, and the water in the water storage tank constantly heats up and reaches the purpose of use.
The utility model is by initial vacuum glass plate 1, final vacuum glass plate 2, the middle inner frame 3 of installing, absorber plate 4, in fill working medium ethylene glycol solution 5, inner frame periphery painting water-proof adhesive 6, install insulation material 7, opsition dependent is put back-up block 8 well, installing outside framework 9 elements such as grade additional forms, feed liquor tube head 10 is installed in inner frame 3 both sides, fluid tube head 11, drain pipe 21, one end connects fluid tube head 11, one termination heat exchanger feed liquor tube head 14, connect heat exchanger 12 in the water storage tank 16, through heat exchanger fluid tube head 13, feed tube 20, tieback is to feed liquor tube head 14, enter inner frame 3, inflation fluid case 15 is installed at heat exchanger feed liquor tube head 14 positions.Safety valve 18 is installed on water storage tank 16 tops.The working medium ethylene glycol solution enters from inflation fluid case 15, and running water has cold water tube head 19 to enter water storage tank, is heated after flowed out by hot water tube head 17.
