Abstract
The utility model provides an internal circulation type solar water heater combining the water tank and the heat collector as one body. The utility model is characterized in that the heat collector is of an inverted cone, is embedded on the upper part of the water tank and submerges in the water, when the water tank is filled with water, the water ascend along the slit between the heat absorption board of the heat collector and the euphotic material, flows back from the upper part and circulates in the water tank. Compared with the flat plate type solar energy water heater, the utility model has the advantages of small occupation area, convenient installation, small heat loss and high sunshine utilization rate.
Description
The utility model belongs to the device that utilizes solar energy heating water
Commercially available solar water heater mostly is flat at present, and heat collector separates placement with water tank, is connected the circulation of its hot and cold water by pipeline.
The utility model provides a kind of water tank and heat collector has been combined as a whole, hot and cold water circulate in the solar water heater that carry out water heater inside.Flat with respect to above-mentioned, connect without pipeline, reduced flow resistance and heat loss, floor space is also less.
Heat collector of the present utility model is inverted circular cone or polygonal pyramid type, and its tapering is between 110-160 °.With respect to flat, sunlight utilization rate height.Because of its horizontal positioned, make sunlight no matter from what angle incident, all can there be the absorber plate of certain area to work.Heat collector is made up of two-layer, internal layer is the absorber plate of black heat absorption water-resistant material, and skin is a light transmissive material, as plastic sheeting, various transparent plastic sheet or glass, between two-layer certain slit is arranged, the back is along its rising so that water can be heated, and the slit is between 0.5-1.5 centimetre.The heat collector level is embedded in the top of cylinder or multi-edge column-shaped water tank, and cone immerses in the water, and internal layer links to each other with the heat collector oral siphon at cone top part, and pipe end mouth and water tank bottom are advisable apart from 4-10 centimetre.Pipe bottom opening place cross-sectional area is between 64-144 centimetre.The heat collector delivery port is opened several openings apart from the awl base along 2-4 centimeters level on absorber plate, the 1/2-3/4 that the opening gross area should be with the high round platform gross area is advisable.
The utility model is to utilize the fluid rising of being heated, the principle design of generation convection current, after water tank is filled with water, sunshine sees through light transmissive material and shines on the absorber plate, the water between the heat transferred slit, water is heated the back along the slit rising, gets back in the water tank by the heat collector delivery port, so circulative convection.
Internal-circulation type solar water heater structure of the present utility model is simple, can adopt multiple material to make.As making water tank and absorber plate with the black rubber film, make light transmissive material hot pressing bonding forming with plastic sheeting, can be made into portable water heater, can use for 1-2 people, be suitable for mobile staff and travelling, also can make the swimming floating thing after the inflation.Also can adopt metal material injection mouldings such as duroplasts or aluminium alloy or be molded into water tank and absorber plate, absorber plate is black or coating black heat absorption water resistant coating, make light transmissive material with plastic sheeting, with a retainer plate three is fixed as one, plastic sheeting can be changed in good time.Can be made into the pot-type boiler that uses for 3-4 people.Its volume is little, and cost is lower, can directly be positioned on the roof, connects the water up and down of water tank with flexible pipe.The time spent also can not taken off collection in the winter time, and absorber plate and film are taken off, and also can make bathtub and use.Also can adopt glass to make light transmissive material, make polygonal pyramid type heat collector, as the 4-6 rib, polygon prism type water tank.On absorber plate, add support frame, with embedding glass gluing sealing on skeleton.This structure, cost are high slightly, but heat absorption efficiency is the highest, are suitable for making relatively large fixed water heater, also should add the hail suppression guard above heat collector.
Cause ponding on the heat collector in order to prevent to rain, the utility model adopts a siphon pipe draining that reaches the heat collector cone top part.
Overflow in order to prevent water tank water filling overfill, the utility model can be installed float-ball type water-level alarm device, and apart from edge 1-2 centimeters the exhaust gap is installed in tank top.
In a word,, the utlity model has following advantage: back taper type heat collector, sunlight utilization rate height with respect to the flat solar water heater, water tank and heat collector integrally combine, and be little to flow resistance, and heat loss is little, and floor space is little, easy for installation, and can adopt various material, being easy to processing, cost is low.
