Abstract

A solar water heater for engineering application to supply heat is composed of casing, internal container, metal-film heater and electric controller. Inert gas able to insulate heat is filled into space between casing and internal container which is the assembly of heat-absorbing body and water container with hexagonal blind holes on its surface for higher heat-absorbing effect. Its advantages include all-weather working, no need of selecting direction, high thermal efficiency and less energy consumption. A number of such water heaters can be parallelly linked to replace boiler.

Description

Engineering solar water heater

The invention belongs to the field that utilizes of solar heat, relate to a kind of engineering solar water heater.

But the utilization of solar energy is energy savings not only, more be of value to environment purification, significant for human existence, thereby bring in constant renewal in the development of this art, utility model patent storage water heater solar-electrical energy water heater (patent No. 96215501.2) discloses a kind of shell that has, inner bag, be equipped with turnover hot water pipe and electric heater in the inner bag, be filled with the water heater of argon gas between shell and the inner bag, has heat supply water effect preferably, but because of the metal material that its inner bag adopted has the also fast characteristics of the fast heat radiation of heat absorption, heat insulation effect is good inadequately, and overcast and rainy all the time according to the time standby carbon nethike embrane resistance heater structure, power savings is relatively poor.

The objective of the invention is to improve the defective of above-mentioned 96215501.2 patents, provide a kind of heat absorption and heat insulation effect good, the novel engineering solar water heater of electric heater Remarkable Energy Saving (parallel connection of this kind water heater number can reach the effect that replaces boiler).

Above-mentioned purpose is realized by following scheme:

Water heater has transparent casing (2) and black inner bag (4), between case (2) and inner bag (4), be filled with inert gas, in the inner chamber of inner bag (4), be equipped with into cold water outlet, hot-water outlet pipe and heater (12), this heater (12) is drawn lead (11) and is patched to the electric controller with light-operated and temperature control circuit (8), inner bag (4) bottom is provided with chassis (3) and sealing gasket (9), case (2) bottom is provided with seal cover chassis (1), cover two-way valve (not drawing among the figure) is housed, there is reflector (5) to place the water heater rear on the support (6), inner bag (4) is the combination that absorber and cistern unite two into one, and described heater (12) is the ion film plating heater.

The planform of inner bag (4) is a cavity, and its external profile is a ball tip circle cone, and the surface is covered with the tubaeform blind hole of six sides of equidistant permutation and combination, and its inwall is smooth ball tip circle cone; The material of inner bag (4) is the black modified plastics of polypropylene (PP); The planform of inner bag (14) is a cavity, and its external profile is a ball tip circle cone, and the surface is covered with the bellows of arranging along axis; The material of inner bag (14) is the metal aluminium that the surface scribbles black absorbing material; Ion film plating heater (12) is to make base plate with pottery or safety glass (15), and plating is with nichrome (Fe-Cr-Ni) heat conducting film (16) and dielectric film (17) and binding post (18) is housed draws lead (11) and constituted on it; Reflector (5) is the flat board that is coated with crome metal.

Accompanying drawing 1 is the structural representation of the embodiment of the invention 1;

Accompanying drawing 2 is embodiment 2 inner-tube structure schematic diagrames;

Accompanying drawing 3 is ion film plating heater structure schematic diagrames;

Accompanying drawing 4 is electric controller circuit theory diagrams.

Reaching embodiment in conjunction with the accompanying drawings further specifies as follows:

Embodiment 1, as shown in Figure 1, water heater is fixed on the support (13), case (2) is with high transparent, high strength, adiabatic, the aging-resistant engineering plastics are made, gabarit is shaped as a ball tip circle taper, between case (2) and inner bag (4), utilize two-way valve (not drawing among the figure) to vacuumize back inert gas injecting-argon gas, have the adiabatic effect of insulation, inner bag (4) is the polypropylene modification black plastic, and endothermic effect is good, its external contour shape is similar to case (2), be ball tip circle cone, the surface is covered with the tubaeform blind hole of six sides of equidistant permutation and combination in respect of 1066, has strengthened endotherm area thus, reduce the refraction of light, improved heat absorption rate.Can receive the solar energy of all directions, and the recipient is not to the restriction of selecting, and double as absorber and cistern unite two into one two kinds of functions, have reduced the internal loss of heat, have improved the thermal efficiency.Reflector (5) places the water heater rear, and it is to be that matrix coating layer of metal chromium constitutes with the plastic plate, the back side of sunlight reflected to irradiation can be received once more.

Embodiment 2, and as shown in Figure 2, inner bag (14) profile is the bellows that its external profile is a ball tip circle cone, is to be made by metallic aluminium, and the surface scribbles black absorbing material, have the function of heat absorption and water storage concurrently.

As shown in Figure 3, the ion film plating heater is on pottery or safety glass base plate (15), be coated with S shape heat conduction nichrome (Fe-Cr-Ni) metal film (16) and insulating barrier (17), its energy-saving effect is splendid, this heater be rainy day or cloudy day all the time according to the time standby, the electric wire (11) that stretches out from its binding post (18) patches to electric controller (8).

As shown in Figure 4, electric controller (8) has the light-operated and temperature control circuit of rectification filtering power display circuit, and when not reaching heating-up temperature, electrical heating is promptly worked when light-operated, also has temperature to show on electric controller, and can set the temperature control scope.Q-heater among the figure, L1, L2-light emitting diode, A1-display.

Because adopt such scheme, the present invention has the following advantages and effect:

1, adopt the polypropylene inner bag, 1066 hexagon blind holes of its outer surface greatly increase Endotherm area, reduce the refraction of light, improved heat absorption rate, cooperate the profile of ball tip circle cone to avoid The desired directionality of general solar energy heat absorbing device, can not have selectively all directions and absorb very To on the object that flows, also using.

2, the ion film plating heater that adopts has fabulous energy-saving effect.

3, inner bag will absorb heat and the water storage function unites two into one, and be filled with indifferent gas between the shell inner bag Body, general solar water heater is established in addition water tank and has been reduced thermal losses, heat absorption and heat insulation effect Fabulous. After tested, 28.4 ℃/h of average of the whole year intensification, the hot water temperature can be between 40-100 ℃ Regulate. Several series connection, the alternative general boiler of its heating effect, but thereby not only heat supply washing Bathe, also can heat, not only energy savings is also contributed huge to environmental protection.

4, floor space is little, and is easy to install, widely applicable.
