The specific embodiment
Like Fig. 3, Fig. 4, shown in Figure 5; A kind of plate integral type solar water heater; Comprise the dull and stereotyped template case 21 that the special anticorrosion aluminium ally section of an employing makes; 15～18mm place covers the cover plate 51 that is provided with a solar energy woven design safety glass on the said plate case 21 of distance; Said plate case 21 is provided with the alternative heat absorption of solar energy rete (meaning not shown in the figures) towards the surface-coated of cover plate 51, and the alternative heat absorption of solar energy rete can adopt magnetron sputtering, colloidal sol spraying, electroless plating materials such as (black chromium) and process to apply.Said plate case 21 belows are provided with a base plate 41; Said cover plate 51, plate case 21 are arranged with frame 71 with the outer ring of base plate 41; And carry out pressing through press strip 61, and it is bonding with weather-proof seccotine that said frame 71 is pieced together the place, angles by four frame sections through four, and frame 71 and plate case 21 contact portions scribble weather proofing sealant; Be provided with heat-insulation layer between said plate case 21 and the base plate 41 and between plate case 21 and the frame 71, this heat-insulation layer is made up of polyurethane plate and blowing agent or inert gas.Particularly, heat-insulation layer between plate case 21 and the base plate 41 31 is filled the solid insulation materials and can be adopted polyurethane plate (or extruded sheet) to add the mode of blowing agent joint filling, also can adopt the mode of whole filling-foam agent.Heat-insulation layer between plate case 21 and base plate 41, the frame 71 (meaning not shown in the figures) can also adopt hollow gas heat-insulation layer, and promptly inner filling inert gas is incubated.
Said frame 71 is provided with four holes; As shown in Figure 5; First threaded end (TE) is a water inlet 27; Second threaded end (TE) along the diagonal positions setting of water inlet 27 is a hot water outlet 24, and two threaded end (TE)s are respectively the thermometric mouth of pipe 26 and the electrical heating mouth of pipe 25 that diagonal is provided with in addition, respectively for temperature probe and electric heating tube are set.The said electrical heating mouth of pipe 25 is arranged on the same side with said hot water outlet 24, and said water inlet 27 is arranged on the same side with the said thermometric mouth of pipe 26.Offer four holes corresponding with threaded end (TE) 24 positions and that can be connected with threaded end (TE) 24 on the said frame 71.
As shown in Figure 5, in order to make water inlet 27 keep constant pressure, said water inlet 27 is provided with step-down constant pressure valve 271; Likewise; Consider that for security performance said hot water outlet 24 is provided with automatic exhaust steam valve 241, the said thermometric mouth of pipe 26 is provided with temperature, pressure safety valve 261.
Be uniformly distributed with in the said plate case 21 and be provided with several dividers 23, said plate case 21 all is divided into several water cavities, 23 two ends of said divider offer the through hole 22 that is used for water circulation.The through hole of offering on the said divider 23 same ends 22 is on same axis; The hole of through hole 22 and frame 71 same ends is also on same axis; Be welded with threaded end (TE) 24 on the through hole 22 of outermost divider 23; As shown in Figure 6, the two ends of said plate case 21 and the divider 23 vertical plugs 28 that are connected with the sealing water cavity.
The size of said plate case 21 can be calculated gained according to actual collector area (50～80 liters/square metre), or (perhaps technology allows) width squeezes and pulls out the specific alloy aluminium section bar as required.If size needs to strengthen, and is as shown in Figure 6, can carries out the piece welding to some plate casees 21, and carry out the pressure leakages check.After qualified, at the alternative heat absorption of a surface-coated solar energy rete towards cover plate.And then carry out other installation, pressing.
Like Fig. 5, shown in Figure 6, installing and using of plate integral type solar water heater is very simple, only needs it is fixed on the roof (being made into the balcony formula just can install on balcony), connects hot water pipe and heating, thermometric electric wire and just can use.During use; After water gets into from water inlet 27; In plate case 21, getting into the water cavity that is formed by each divider 23 through through hole 22, be divided into some roads current, absorbs heat under solar radiation in the surface that plate case 21 has applied the alternative rete that absorbs heat of solar energy; Because plate case 21 adopts special anticorrosion aluminium to make; Aluminum metal is transmitted the heat that absorbed fast and is reached the function of heating through plate case 21 inwalls and water contact heat-exchanging, and the current of heating use from hot water outlet 24 water outlets with cold water mixing formation free convection, finally heated water.If at rainy weather, can supply user's domestic water to use through the water in the electric heater for heating plate case of the electrical heating mouth of pipe 25.
The beneficial effect of the integral type solar energy heat hydrophone of the utility model is embodied in:
1) good looking appearance, compactness: the integral type solar energy heat hydrophone just as the flat-plate solar heat collector of a thickening has surmounted the all-in-one of glass tube with vacuum and the dull and stereotyped all-in-one that flat plate collector adds water tank on attractive in appearance.The burden that has not had water tank is than all compact brief, the saving installing space of existing any pattern solar water heater;
2) simple and flexible is installed: the integral type solar energy heat hydrophone is intensive as a whole with solar water heating system factory finished productization, just can normally move with the control power supply as long as connect water inlet pipe and water outlet pipe, without any need for the adjustment test.Not only can independently use by monolithic, can also use with the aggregate erection of condition N piece as required.
3) can be used as construction set: but the cover plate of integral type solar energy heat hydrophone is safety glass, plate case pay attention to the mechanical structure design and adopt particular aluminum alloy to squeeze drawing form, the high bearing operation of mechanical strength, periphery and bottom have good insulation, possess good whole water resistance and mechanical strength; High especially with the degrees of fusion of architecture-integral, if can be used as construction set fully, scale standard production uses.
4) cost performance is high: employing particular aluminum alloy integral slab case has substituted the plate core of original heat collector aluminium sheet, copper pipe and the system in combination of insulation press-bearing water tank has not only reached with aluminium for copper; Also make original indirect heat exchange or long being reduced in the integral slab case accomplish apart from heat exchange; Rate of heat exchange and efficient promote significantly on the one hand, and system cost descends significantly on the other hand.
5) the cost cost is low: because the utility model adopts special aluminium alloy to process the plate case; Piece welding between the plate case and the welding between plate case and the plug also all only need to adopt common argon arc welding to get final product; Avoid the high cost investment of laser weld in the prior art, thereby make the cost of the dull and stereotyped relatively pressure bearing system of the utility model reduce about 30%.
6) engineering is terse, market prospects good: develop series of products such as roof type, balcony formula according to the working mechanism of integral type solar energy heat hydrophone; Make the solar engineering system become also more terse than vacuum tube engineering system; Both had certain cost advantage; Have flat plate collector and the perfect advantage that merges of building again, will promote the great development of China's solar energy optical-thermal application prospect.
The utility model still has numerous embodiments, and all employing equivalents or equivalent transformation and all technical schemes of forming all drop within the protection domain of the utility model.
