Abstract

The utility model relates to a solar energy water heater with a vacuum glass container, comprising a heat collector, a water storage tank, a corresponding water transport pipeline, and a valve. The solar energy water heater with a vacuum glass container is characterized in that the heat collector is a spherical or cylindrical vacuum glass container with a water inlet and a water outlet, and a blackening layer is arranged outside an inner glass shell. The water storage tank is the structural body of a vacuum flask whose upper part is provided with a cylinder opening and lower part is provided with an outlet and an inlet, further, paraboloidal focusing and an automatic tracking sun system can be used for supplying boiled water and steam, and the solar energy water heater with a vacuum glass container is sued as a solar boiler. If the volume of the solar energy water heater with a vacuum glass container is large enough, the water storage tank can be omitted. The solar energy water heater with a vacuum glass container has the advantages of high heat efficiency, acid resistance, strong basicity, and low cost. The solar energy water heater with a vacuum glass container is an ideal multi-purpose solar energy water heater.

Description

Vacuum glass container solar water heater

The utility model relates to a kind of vacuum glass container solar water heater.

Existing glass vacuum tube type heat collector, handful hammer heat collector etc., the inevitable variation with angle of incidence of sunlight of its daylighting area has bigger variation, therefore be difficult to make full use of solar radiant heat, if adopt the manual direction of heat collector and the method for angle adjusted, it is cumbersome then not only to waste time and energy, and also is difficult to reach optimum efficiency; Prior art must have the not member of acid-alkali-corrosive-resisting such as hot water water storage device usually again.

The objective of the invention is to overcome above shortcoming, but provide a kind of acid and alkali-resistance and daylighting area not to change basically, thereby can make full use of solar radiant heat, improve the vacuum glass container solar water heater of the thermal efficiency greatly with angle of incidence of sunlight.

The utility model specialized designs one double-deck glass bulb is arranged, the spherical or tubular glass heat collector that vacuumizes therebetween both was incubated, and guaranteed that again daylighting area is constant substantially in the whole day; Further utilize existing parabolic focusing system that it is focused on, to make full use of sunlight; If above-mentioned spherical or tubular heat collector yardstick enough greatly the time, then saves storage tank because of the function that itself has storage tank concurrently; If necessary, then specialized designs is incubated corrosion resistant storage tank again: promptly glass system has an inside and outside courage, the cylindrical body of the silver-plated and similar vacuum flask structure that vacuumizes of interlayer.

Obviously the utility model thermal efficiency height, resistance to acids and bases is strong, and is simple in structure, cost is low, not only can be used as high efficiency general solar water heater, its type of focus also can supply boiling water, steam, use as SOLAR BOILER.

Provide specific embodiment of the utility model in detail below in conjunction with accompanying drawing.

Fig. 1, the utility model general structure schematic diagram.

Fig. 2, spherical collector structure schematic diagram.

Fig. 3, storage tank structure schematic diagram.

Fig. 4, tubular heat collector front view.

Fig. 5, tubular heat collector cutaway view.

Wherein: 1. delivery port; 2. support; 3. water inlet; 4. heat collector; 5. storage tank; 6. pipeline; 7. import; 8. showering; 9 outlets; 10. hot water circuit valve; 11. water intaking valve; 12. focusing mirror; 13. exhaust outlet; 14. vacuum layer; 15. double-deck glass bulb; 16. sleeve pipe; 17. pipe clamp; 18. blackout layer; 19. inside and outside courage; 20. coating; 21. hard rubber piece.

As Fig. 1, the heat collector 4, that can receive solar radiation and cold water heated of delivery port 1 with water inlet 3 has the hot water storage tank 5 of water intaking valve 11 to the utility model and aqueduct 6 and showering 8 and hot water circuit valve 10 are formed accordingly by having.Above-mentioned heat collector 4 is for being fixed on a spherical vacuum glass container on the support 2, promptly be the spherical double-deck glass bulb 15 of vacuum layer 14 therebetween, and it has water inlet 3, which is provided with delivery port 1, for absorbing solar radiant heat more, glass bulb scribbles blackout layer 18 outward in it again, as Fig. 2, the area that obvious this heat collector from morning to night receives sunlight is all identical, is a kind of omnibearing solar thermal collector.As above-mentioned heat collector 4 insulation constructions identical be the tubular heat collector, as Fig. 4, Fig. 5, it is that the cross section of water in-out port 1,3 is arranged is that the double-deck glass bulb 15 of U type is harmonious and forms and with high warm sleeve 16 and pipe clamp 17 sealing chuckings in two terminations, and 15 of double-deck glass bulbs are vacuum layer 14, interior glass bulb scribbles blackout layer 18 outward, considers that vapor outlet port is also established an exhaust outlet 13 in case of necessity.

If it is above-mentioned spherical or tubular heat collector 4 yardsticks are enough big.Mainly refer to relative practical application, then can save a storage tank 5, become the water heater of not being with storage tank, be simple embodiment of the present utility model; When needing, there is little nozzle A (can be used as observation panel) top that custom-designed storage tank 5 is glass systems, be provided with the cylindrical body that inside and outside courage 19 is arranged of outlet 9 and import 7 below, the reflected coat layer 20 that silver-plated or aluminium are arranged on the envelope walls, vacuum layer 14 is arranged therebetween, and its structure is as the vacuum flask with premium properties.Consider and bear certain vacuum pressure, can reinforce by hard rubber piece 21 in 19 in inside and outside courage.Above-mentioned outlet [9] communicates with hot water circuit valve [10] and water intaking valve [11], and import [7] communicates with the delivery port [1] and the showering [8] of heat collector [4].

For to the greatest extent many solar radiations that compiles, also above-mentioned spherical or tubular heat collector 4 can be fixed on the focus of parabolic focusing mirror 12 with support 2.As Fig. 1: also can utilize existing parabolic line focus or Fresnel lens line focus and be equipped with auto sun-tracking system (figure slightly) so that heat collector 4 obtains optimum efficiency to above-mentioned tubular heat collector 4.

In sum, the utility model is simple in structure, and cost is low, and resistance to acids and bases is strong, and thermal efficiency height is the desirable solar water heater of multipurpose.
