Abstract

The utility model relates to a microcirculation type household solar energy water-heater, which is designed according to the technique of solar energy utilization and the theory of fluid microcirculation. The utility model not only has the characteristics of a board-tube type water heater, but also integrates the advantages of a closed basking type water heater. The utility model is composed of a water storage tank, a heat collector, a transparent cover board, an insulation housing, a supporting frame, etc. The structure is characterized in that an upper manifold collecting pipe is canceled, a water tank and heat collecting and juxtaposed pipes are made into an integral structure, namely, each heat collecting juxtaposed pipe is communicated with the water tank directly.

Description

Microcirculation type household solar energy water-heater

The utility model relates to solar utilization technique, is according to the microcirculation principle, improves domestic solar water heater's structural design, thereby has improved the thermal efficiency, has saved raw material, has reduced cost, more helps applying of domestic solar water heater.

Existing domestic solar water heater's structure is divided into two kinds of closing-sunning type and band-tube types substantially.The former be water tank directly as heat collector, it is simple in structure, price is low, but the thermal efficiency is low, uses the longevity short.The band-tube type water heater is the water that utilizes in the thermal-arrest plate absorption luminous energy heating thermal-arrest comb, carries out the atural beat circulation through the water at low temperature of upper and lower manifold trunk and storage tank.Its thermal efficiency is higher than the former, but cost is higher.

The purpose of this utility model is to adopt the microcirculation principle, and comprehensively the advantage of the two is improved structural design, and a kind of thermal efficiency height is provided, and saves raw material, reduces the domestic solar-energy water heater of cost.

The purpose of this utility model realizes by the following method:

Manifold trunk in the cancellation is made overall structure with storage tank and thermal-arrest comb, i.e. all direct the and storage tank connection of each root thermal-arrest comb.Each root thermal-arrest comb all is a little loop-body like this, that is to say that the water that shines heat enters water tank along the tube wall rising, and the water at low temperature in the water tank refluxes along the tube wall opposite side, makes each root thermal-arrest comb all become a circulatory system with storage tank.Obviously the such circulatory system and the heat circulating system of existing tube-sheet type water heater are completely different.We are referred to as microcirculqtory system.Simultaneously, the advantage of comprehensive closing-sunning type water heater, with storage tank make heat collector towards sunny side, remainder is done housings close by insulation material, prevents thermal losses, has so both saved raw material, has improved the whole thermal efficiency again.

Fig. 1 is a microcirculation formula domestic solar water heater front view.

Fig. 2 is a microcirculation formula domestic solar water heater sectional view.

Below in conjunction with drawings and Examples the utility model is further elaborated.

The utility model mainly is made up of heat collector insulation shell (1), collecting plate (2), heat collection rack pipes (3), lower manifold trunk (4), storage tank (5), water tank heat preserving housing (6), overflow pipe (9), water monitor (10) and bracing frame (11) etc.

The utility model structure is as shown in the figure: the upper end of being fixed in the some parallel heat collection rack pipes (3) on the collecting plate (2) is welded in the bottom of storage tank (5), and the lower end is welded on the lower manifold trunk pipe (4). Integral installation and encapsulates with transparent cover plate (7) in heat collector insulation shell (1). As heat collector, by transparent cover plate (8) absorbing light energy, remainder is encapsulated by water tank heat preserving housing (6) storage tank (5) towards sunny side. The top of storage tank (5) is provided with overflow pipe (9). Cold water enters storage tank (5) by lower manifold trunk (4) through heat collection rack pipes (3), give when deciding water level when reaching, place the sensing element contacting circuit of the inner water monitor (10) of overflow pipe (9), sounding alarm, at this moment, close inlet valve, unnecessary water is discharged by overflow pipe (9).

Because be provided with water monitor (10), down manifold trunk (4) both had been water inlet pipe, again as the hot water delivery pipe, only needed the conversion penstock, hot water is still exported from manifold trunk (4) down.

This water heater is provided with the rear support stand (11) of angle adjustable, and the bottom supports of heat collector insulation shell (1) is as another strong point.

Owing to taked the said structure design, the utility model is compared with the band-tube type water heater of existing congenerous, raw material (the light copper material just saves 1/5) have not only been saved, cost reduces (10～15) %, and because every thermal-arrest comb is all participated in the water circulation directly, thereby the circulation sectional area that makes the more original last manifold trunk of water circulation sectional area increases (about 2～2.5 times) greatly, and the water circulation resistance has reduced with regard to corresponding.Simultaneously, because increase the thermal-arrest usefulness of storage tank, make overall thermal efficient improve (10～15) %, the also corresponding raising of the heat production water yield (10～15) %.The overall structure of this water heater is compact more, installs and uses conveniently, more helps vast urban and rural residents and promotes the use of.

Embodiment: plate pipe heat collector daylighting area is 0.81m ², storage tank heat collector daylighting area is 0.18m ², total daylighting area 0.99m ², transparent cover plate is a plate glass, storage tank is welded with sheet metal, capacity is 60 kilograms, and following manifold trunk and thermal-arrest comb adopt copper tube, insulation material styrofoam, all there are feet and adjustable supporter in water heater bottom and back, so that be installed on the various buildings.
