CN2380865Y - Solar water-heater of closed soaking-up-sun to accumulate energy - Google Patents

Abstract

The utility model relates to a solar water-heater of closed soaking-up-sun to accumulate energy, which is mainly composed of a water tank, a heat-insulation layer, a transparent cover plate and a support frame. The water tank is composed of a water bucket and a heating plate which are communicated and made of stainless steel materials. The water tank is provided with an upper and a lower water pipes, a drainage pipe and a blow-off pipe. The insulation layer of the heating plate forms a box shape, which is formed into integration with the insulation layer of the water bucket. The heating plate is double-layer, and a gap between the two layers is about 1 millimeter. The gap is controlled by rivets or spot welding; the circulation caliber of hot water and cold water are same with the water bucket in length; thus, the circulation is fast. An aluminum protective layer is arranged out of the thermal insulation layer. Compared with the bucket type water heater, the water temperature is higher more than 15-20DEG. C with the same condition within a day; the utility model has the advantages of less overnight radiation, temperature rising all days, hot water without rust, and a plurality of purposes. The service life of stainless steel is 30 to 40 years.

Description

The closed soaking-up-sun to accumulate energy solar water heater

The main distinction of this closed soaking-up-sun to accumulate energy solar water heater and at present existing closing-sunning type water heater is that heat is imitated high and long-pending energy.Now be explained as follows:

Purpose is that the present passive solarenergy water heater's heat of solution effect is low, and long-pending energy is unhygienic, the shortcoming that purposes is lacked and service life is short.

This kind water heater mainly is made up of five parts, now contrasts description of drawings: the part that is filled with water is water tank Fig. 3, poly-stupid foam insulation 7, and layer 2-3 transparent cover plate 9, support 8, outermost layer are protective layers.Following step-by-step instructions: 1. water tank is made of flat bucket 3 for sleeping in and the heated sheet 1 that occupies its below that is communicated with it.The water tank material is a stainless sheet steel, thickness 0.4-0.5 millimeter.Aluminium alloy sheet is good.Volume is advisable about 80 liters.Method for production: earlier 1 * 2.5 meter stainless sheet steel is utilized the stage casing to make diameter earlier, then remaining two symmetrical parallel are prolonged the Shen and go down, make heated sheet, be communicated with the bucket 3 of top for the 31-32 centimeter length is 1 meter a bucket 3.A slice blacking on the sunny side, the four edges of heated sheet 1 except that one side of top with bucket is communicated with, remaining 3 limits need be withheld two-layer thin plate flanging, soldering does not make and leaks.For two layers of thin small drum for marking time tripe after the anti-water filling, rise bad, must be two-layer with rivet 2 break-through, the gap that 2, two interlayers leave 1 millimeter is lived in the two sides weldering.The purpose of staying the gap is to allow its water flowing.The control method in gap is: shimming is enclosed within on the rivet 2 between two-layer.Can replace with spot welding during without rivet, pad weldering two-layer and therebetween is firmly got final product.The purpose of control gap is both to have allowed water flowing in it like this, and not allowing again has too much water in it.Thereby make the very fast solarization of water heat, deliver in the heat-preserving container in time.Meanwhile, original cold water in the heat-preserving container 3 sinks to naturally to participate in the heated sheet 1 and is heated.So move in circles, the water of bucket 3 constantly heats up.Whole dress water section has 3 water service pipes, and 4 is upper and lower conduit among the figure, and 5 is drainpipe, and 6 is blow-off pipe.2. heat-insulation layer 7: the heat-insulation layer material is poly-stupid foamed plastics, a moulded section base.The other press mold of semicircle of bucket top.Heat-insulation layer protection all dress water sections except that heated sheet faces south simultaneously.The thickness of heat-insulation layer: 4-5 centimetre on every side in bucket 3,3 centimetres of remainders.3. transparent cover plate 9: transparent cover plate is above heated sheet.Constitute by glass layer 2-3 or glass and one deck lucite.Can only cover the superiors during with lucite.With present closing-sunning type water heater single laying of plank covering ratio, the both transparent heat of adopting of this kind cover plate is good, can protect heated sheet top layer heat again.4. outermost layer is made protective layer (among the figure and do not show) with galvanized iron sheet or aluminium skin and other resistant materials.5. support 8: support makes water heater heated sheet and sunshine at an angle of 90 as far as possible, can make for this reason adjustable, when putting to south by west 10-15 ° angle.

Effect: 1. heat is imitated high.With the ratio of present closing-sunning type, the multi-layer transparent cover plate that it has, heated sheet not only is heated but also its surperficial heat is too much distributed, thereby very fast cold water in the plate is shone delivered to bucket on the heat and kept heat.About 0.75 square metre of heated sheet area, be the direct heating surface area of bucket formula and electron tubes type at present 1.5-2 doubly.The same terms next day ratio bucket formula a water heater temperature exceed more than 15-20 ℃.2. the hot water purposes is many.Dress water-bound material is a stainless steel, and hot water is rustless.The dish etc. of can having a bath, cook, do washing.3. can amass energy.Because heat-insulating property is better than other closing-sunning type water heaters, so the hot water that shone the same day is not as needing or when hot inadequately, one night of winter is lowered the temperature 5-8 ℃, and one night of summer is lowered the temperature 4-6 ℃, can amass energy continuously in second day, and temperature exceeded 15-25 ℃ in comparable first day.Such one is colder at weather, shines in one day when not hot, can continuous two days it be shone heat, has prolonged annual practical fate.The 2nd, run into still having the hot water of the day before yesterday to supply when overcast and rainy.The 3rd, can often guarantee had hot water in 24 hours.4. it is low to manufacture easy cost.Both can manufacture by hand, but batch production production again.5. the life-span is long.Generally need not keep in repair for many years, stainless steel material reaches 30-40 service life.

The drawing explanation:

1. 3 width of cloth figure are left front three-dimensional view.Fig. 1 is a close-up view, and Fig. 2 is a cutaway view, and Fig. 3 is water tank figure (being made of the two connection heated sheet and bucket).Among the figure size can ± 2 centimetres.

2. mark: 1, heated sheet 2, rivet or spot welding point 3, bucket 4, upper and lower conduit.(go up cold water and following hot water with) 5, drainpipe (filling up water enters indoor) 6, blow-off pipe (break seal during the cleaning dirt, seal at ordinary times, a tube head break-through lower floor, the mouth of pipe is apart from inferior horn 2-3 centimetre) 7, heat-insulation layer 8, support 9, transparent cover plate
