Description

Flat-box-type solar water heater

The utility model relates to a kind of people's life and the hot water facility of drinking water.Its primary structure feature is the abnormally-structured of absorber and absorber of making of special stainless steel/steel composite material and cyclic water tank etc.

At present commercially available various solar water heaters have been the hot water facility that people accept extensively and like, though that it has is economical and practical, convenient and healthy, energy-saving safe, the long-term plurality of advantages such as be benefited of investment once, but still not all roses.Major defect is: because the material that the making solar water heater generally adopts mostly is cold-rolled steel sheet, galvanized steel plain sheet, even material such as copper, aluminium, stainless steel, plastics, copper aluminium is compound, water heater absorber structural design is unreasonable in addition, thus existing all kinds of water heater all exist corrosion-resistant, polluted water to some extent, should not live drink, such-and-such problems such as service life is short, mechanical strength is low, cost is high, thermal property difference.

The purpose of this utility model is to avoid above-mentioned weak point of the prior art and a kind of structural design novelty, rationally is provided, single unit system is corrosion-resistant, the life-span is long, pollution-free, mechanical strength is high, thermal property good, reasonable price, live and drink shared, the desirable flat box type solar energy water heater device of practicality more economically.

The purpose of this utility model can be finished by following technical measures: by water tank and the heat collector solar water heater dimerous that links with it, the water tank part mainly has outer water tank 1, heat-insulation layer 8, cyclic water tank 19, steel band 21, pipe clamp 17, connects sebific duct 18; The heat collector part mainly has transparent cover plate 4, absorber 5, a left side (right side) thermal insulation board 3, goes up (descending) thermal insulation board 10, outside framework 6, bedframe 11, lower shoe 12, absorber lower shoe 13, gripper shoe 15.Absorber 5 be by two respectively punching press have the last heat-absorbing plate core 22 of a semi-circular recesses and several trapezoidal groove runners to weld to constitute with following heat-absorbing plate core 23.Absorber 5, cyclic water tank 19 and outside framework 6 all adopt stainless steel/steel composite sheet material to make.

Runner 24 in the utility model absorber 5, the cross section of runner 25 are hexagon and circle respectively, and the runner spacing is 60～64mm.Spacing between the last heat-absorbing plate core 22 of transparent cover plate 4 and absorber 5 is 25～40mm.

Embodiment: the 5th part of this specification and accompanying drawing 1--7 have showed complete embodiment of the utility model.Describe in detail below in conjunction with accompanying drawing: adopt existing processing and manufacturing technology that cyclic water tank 19 is loaded among the outer water tank 1, between outer water tank 1 and the cyclic water tank 19 with rock wool heat-preservation layer 8 heat-insulation and heat-preservation.Tapping screw 20 is fixed in 2 steel bands 21 to outer water tank 1 on the bedframe 11 of water heater, and two connection sebific ducts 18 link with heat collector by pipe clamp 17, tapping screw 16.

Absorber 5 is to be formed by two one time punching molded respectively last heat-absorbing plate cores 22 and following heat-absorbing plate core 23 roll weldings.The top of absorber 5 is the thick plate glass transparent cover plate 4 of 3mm, below the absorber lower shoe of making for glass-reinforced plastic material 13; Left side (right side) thermal insulation board 3 around the absorber 5, last (descending) thermal insulation board 10 all adopt the thick polyphenyl foam plastic plate of 30～50mm to make, to reach the effect of heat-insulation and heat-preservation.The left and right, upper and lower of whole heat collector box body combines as a whole transparent cover plate 4, a left side (right side) thermal insulation board 3, absorber 5, last (descending) thermal insulation board 10, lower shoe 12, absorber lower shoe 13 by screw 2a, packing ring 2b, sealing gasket 7, sealing ring 14, gripper shoe 15, bedframe 11, outside framework 6.In order to reduce heat loss, improve collecting efficiency, the distance between the last heat-absorbing plate core 22 of transparent cover plate 4 and absorber 5 is 25～40mm.Recommending the runner spacing simultaneously is that 60～64mm is to obtain the best fin thermal efficiency.The utility model absorber 5, cyclic water tank 19 and outside framework 6 all adopt the stainless steel/steel composite sheet of 0.5 millimeters thick to make.
