Abstract
The utility model relates to a high-effective solar energy water supply device, comprising a self-circulation water tank 3 and a heat collecting tank 4. The utility model is characterized in that an inflated heat absorbing plate 5 compounded by aluminium is utilized, effective area is utilized fully, and heat efficiency reaches to 70 %. The temperature of water with 100 kg can reach between 40 DEG C and 85 DEG C only via light irradiation more than three hours at all seasons under the condition of no need of external energy through the utility model. The high-effective solar energy water supply device is favorable for popularizing and utilizing among wide urban and rural residents. The utility model can be made into various types such as wall-attachment type, portable type, etc. The high-effective solar energy water supply device is further favorable for the popularization and application of solar water heaters.
Description
The utility model belongs to heating heat-obtaining technology, particularly solar energy hot water supply technology.
Existingly utilize the solar energy heat-obtaining, though especially the solar water heater technology is extensively promoted.But the thermal efficiency that how further to improve solar water heater is this field knowledgeable people always be concerned about and the institute make great efforts the solution problem.The installation of solar water heater has directly influenced the popularization and the utilization of solar water heater.Therefore this also is that lots of manufacturers and user rather pay close attention to.
The purpose of this utility model is to provide a kind of high-efficiency solar hot-water supply device to society.
The utility model is to realize like this, a kind of high-efficiency solar hot water apparatus, comprise self-loopa water tank 3 and heat-collecting box 4, it is characterized in that adopting composite aluminum-aluminum bullating type absorber plate 5, make full use of effective area, reduced thermal resistance, make the thermal efficiency reach 70%, absorber plate 5 fuses with last lower collector pipe, endothermic tube, and heat-conducting efficiency is higher than glued formula, welded type, type village formula heat absorption conduction pattern far away.Around improving the thermal efficiency, the technical program has also been taked several measures, the one, one deck specular layer 16 is arranged below absorber plate 5, make lost being inhibited of heat radiation at absorber plate 5 back sides, good heat-insulating material makes the conduction heat waste be reduced to minimum simultaneously, the 2nd, lifting pipe 2 built-in water tanks 3 inside, water pipe 2 is by straight-through its top liquid level in water tank 3 bottoms, thereby the thermal losses that makes tedge is converted into effective heat conduction, also saved simultaneously the heat-insulation layer of tedge, the 3rd, heat-collecting box 4 fronts are provided with layer glass 13,14, in the middle of sealing ring 12 is arranged, make air blanketing static fully, become a kind of good conduction heat guard.On the other hand, surface one deck lucite, has good light transmittance, almost can see through all solar radiations, inner layer glass is colourless plate glass, though its translucidus is slightly poorer than lucite, the infra-red radiation of wavelength X 〉=4.5 μ m is complete opaque shape, this has just suppressed the positive thermal radiation loss of absorber plate 5 admirably.The 4th, oblateness 17 is adopted in the circulation line cross section, and absorber plate 5 water capacities reduce (1.5m greatly
2Be the 1.2L capacity), thereby reduced starting load, simultaneously, because it has bigger girth, flow resistance does not but increase, the flow velocity of tube fluid is increased, finally improved the heat exchanger effectiveness of absorber plate and fluid, the pipeline shape shown in 17 can repeatedly absorb solar irradiation, has further improved absorptivity, owing to taked top these technical measures, thereby improved the thermal efficiency of apparatus for heating water by solar energy greatly.
Realization of the present utility model provides a kind of high-efficiency solar hot-water supply device to society, under the situation that does not need outside resources, utilizes the Natural Circulation principle that water is heated up.Throughout the year, as long as illumination more than 3 hours is arranged every day, the 100kg water temperature just can reach 40 ℃～85 ℃.Be very advantageous in vast urban and rural residents and promote the use of solar water heater.Certainly will bring fine prospect to solar water heater.
Accompanying drawing 1 is an embodiment schematic diagram of the present utility model.
Accompanying drawing 2 is embodiment heat-collecting box profiles of the present utility model.
Float switch 1, lifting pipe 2, water tank 3, heat-collecting box 4, absorber plate 5, feed pipe 6, reversal valve 7, outlet pipe 8, choke valve 9,10, blank holder 11, sealing ring 12, double glazing 13,14, electric heater 15, specular layer 16, absorber plate circulation line cross sectional shape 17 among the figure.
Further narrate the technical solution of the utility model below in conjunction with accompanying drawing.A kind of high-efficiency solar hot-water supply device, comprise self-loopa water tank 3 and heat-collecting box 4, one deck is a lucite 13 above the heat-collecting box 4, and one deck is dull and stereotyped flint glass 14 below lucite 13, blank holder 11 and sealing ring 12 are arranged between the layer glass, form good conduction heat guard.Being aluminium aluminium inflation type absorber plate 5 under two layers of glass 13,14, is specular layer 16 below again.Heat-collecting box 4 is connected with water tank 3 by lifting pipe 2.For the utility model also can be used overcast and rainy, or be shorter than 3 hours in light application time and use under the situation, can be in water tank 3 affix electric heater 15 and safety device thereof, with further raising water temperature.When implementing the utility model, can make the wall built-up style to heat-collecting box 4, the following floor resident of being convenient to live on the top floor uses, and is directly installed on the balcony during use or hangs on the exterior wall of Chaoyang to get final product.The another embodiment of the utility model such as Fig. 3 show heat-collecting box 4 made portable suitcase style, and closing profile is suitcase, is opened for heat-collecting box, as shown in Figure 3, as long as connect water tank.Make things convenient for the field work place to use.
