Abstract
The utility model relates to a solar water heater, which comprises a water tank provided with a water inlet and a water outlet, and a selective absorbing coating; the inner surface or the outer surface of part of the water tank wall is coated by the selective absorbing coating; the water tank wall coated by the selective absorbing coating can be made from transparent material; an overburden layer made from transparent material can be arranged above the water tank wall coated by the selective absorbing coating and connected with the water tank wall coated by the selective absorbing coating. The utility model has the advantages of simple structure, easy fabrication, low cost, perfect combination with the building, and facility to be connected into large area hot water supply engineering.
Description
Technical field
The utility model relates to solar water heater.
Background technology
Present solar water heater mainly comprises water tank and heat collector two large divisions, the water in the heat collector absorb behind the solar energy with water tank in water carry out the heat exchange of various ways such as convection current, the water in the water tank heats up gradually.But owing to water tank, heat collector two large divisions fail organically to combine, caused present water heater complex structure, volume expands, and production process is many, the cost height.
Summary of the invention
The technical problem that technical problem is the solar water heater structure complexity, production process is many, cost is high that the utility model solves.
Solar water heater described in the utility model comprises the water tank of bringing delivery port into, and coating for selective absorption scribbles coating for selective absorption at the inner surface or the outer surface of part water tank tank wall.
As to improvement of the present utility model, the tank wall that scribbles coating for selective absorption can be made by transparent material, and described transparent material can be vacuum glass, double glazing or single-glass.
As to another kind of improvement the of the present utility model, scribbling the relative water tank tank wall of the tank wall of coating for selective absorption with inner surface can be made by transparent material, and described transparent material can be vacuum glass, double glazing or single-glass.
As to further improvement of the utility model, in the above solar water heater, the water tank tank wall that does not scribble coating for selective absorption can be by inside and outside two-layer the composition, but inside and outside two-layer between fill insulant material.
The beneficial effects of the utility model: (1) unites two into one water tank and heat collector; (2) simple in structure, easy to manufacture; (2) with low cost; (3) can with the building perfect adaptation; (4) be easy to connect into large-area hot water engineering.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment 1.
Fig. 2 is the structural representation of the utility model embodiment 2.
Fig. 3 is that the A of Fig. 2 is to view.
The specific embodiment
Among Fig. 1, the inner surface 5 of the tank wall 1 of water tank scribbles coating for selective absorption, and the water tank tank wall relative with tank wall 16 made by double glazing; Have water inlet 13, delivery port 14 in the bottom of water tank.This embodiment does not have support, can directly be placed on the roofing, realizes and the building perfect adaptation.Can be interconnected by the tube connector 11 that is connected the water tank side between many these solar water heaters, form large-area hot-water supply engineering.
Among this embodiment, coating for selective absorption also can not be coated in the inner surface 5 of tank wall 1, and is coated in the inner surface 15 of the case tank wall of being made by double glazing 6.
Among Fig. 2,3, tank wall 4 is made by stainless steel, and its outer surface scribbles coating for selective absorption, and there is the cover layer of being made by vacuum glass 2 top of tank wall 4; The water tank tank wall that does not scribble coating for selective absorption is by internal layer 8, and outer 9 form, and internal layer 8 can be made by stainless steel, and outer 9 can be made by general steel plate, are filled with insulation material 12 between the ectonexine; Tank wall 4 is with internal layer 8, skin 9 are connected respectively; The intake-outlet 3 that the bottom of water tank has into water, water outlet to unite two into one, top have exhaust (overflow) mouth 7; Be connected with support 10 on the water tank.Be connected with tube connector 11 in the water tank side, can make between many solar water heaters by this tube connector to be interconnected, form large-area hot-water supply engineering.
