Abstract

The utility model relates to a straight-through vacuum pipe solar energy water heater, which comprises a heat collector 1, a water storage tank 2, a three-way valve 3, a connecting pipeline 4, the outer wall 5 of a vacuum pipe, the inner wall 6 of the vacuum pipe, an air pumping nozzle 7 of the vacuum pipe, the vacuum pipe 8, a lower water collecting box 9, an upper water collecting box 10, a water inlet 11 of the heat collector, a water outlet 12 of the heat collector, an installation hole of the vacuum pipe, a sealing ring 13, and a reflecting plate 14 of the heat collector. The vacuum pipe heat collector can be separated from the water storage tank. The vacuum pipe heat collector can be hung on a balcony or outside the wall of a house. The water storage tank is arranged in any indoor position which is parallel to the heat collector.

Description

Straight-through vacuum tube solar water heater

The utility model relates to a kind of straight-through vacuum tube solar water heater.

At present, the solar vacuum-tube water heater of production and selling in the society is subjected to people's welcome with its good heat insulating.But the lower end of its vacuum tube is sealing, and the upper end is a water inlet, is again delivery port, makes that hot water behind the thermal-arrest is up to carry out simultaneously with cold water is descending, produces the water resistance phenomenon, and the thermal efficiency reduces.Moreover because vacuum tube has only upper end open, storage tank is installed in the top of vacuum tube collector, becomes inseparable integral body, installs not convenient, especially inconvenient especially in the low layer resident family installation of high-rise building.

The purpose of this utility model is in order to provide a kind of solar water heater, especially a kind of straight-through vacuum tube solar water heater.The characteristic that it utilizes hot water rising cold water to descend makes in the vacuum tube hot water behind the thermal-arrest rise to discharge from the upper end to enter storage tank top, and the cold water of storage tank bottom is entered by the lower end of vacuum tube simultaneously, eliminates the water resistance phenomenon, forms Natural Circulation.Therefore, vacuum tube collector can separate with storage tank, and vacuum tube collector can be suspended on outside the balcony or wall of resident family, and storage tank is placed in indoor any position parallel with heat collector.

In order to achieve the above object, the utility model comprises heat collector 1, storage tank 2, triple valve 3, connecting line 4.Vacuum tube outer wall 5, vacuum tube inwall 6, vacuum tube are bled and are chewed 7, vacuum tube 8, following collecting box 9, last collecting box 10, heat collector water inlet 11, heat collector delivery port 12, vacuum tube installing hole and sealing ring 13, heat collector reflecting plate 14, hot water inlet 15, hot water outlet 16, cold water inlet 17, cold delivery port 18, insulation material 19.Described vacuum tube is the straight pipe of both ends open, and vacuum tube outer wall 5 and vacuum tube inwall 6 are vacuum state, and vacuum tube outer wall 5 outsides scribble black absorbing material, and vacuum tube is bled and chewed 7 and be placed on the vacuum tube outer wall 5; Following collecting box 9 and last collecting box 10 are installed on the heat collector reflecting plate 14, are the double-layer hollow body, and fill insulant material 19 between the bilayer, are provided with vacuum tube installing hole and sealing ring 13 and vacuum tube and are sealed and matched; Storage tank is the double-layer hollow body, fill insulant material 19 between the bilayer, top is provided with hot water inlet 15 and is connected with hot water outlet 16 with heat collector delivery port 12 and is connected with shower nozzle, and the bottom is provided with cold water inlet 17 and is connected with running water pipe with cold delivery port 18 through triple valve 3 and is connected with heat collector water inlet 11.

The utlity model has following characteristics:

1. separating of heat collector and storage tank, make installation more random and convenient; 2. convection current water resistance phenomenon has been eliminated in the application of straight-through vacuum pipe, has improved the thermal efficiency, and under equal heating-up temperature and volume situation, collector area reduces, and cost descends; 3. under the characteristic that hot water rising cold water descends, as long as solar radiation is arranged, just the top of storage tank can produce hot water rapidly, at short notice both can be for people to use.

Below in conjunction with accompanying drawing and example the utility model is further specified, wherein:

Fig. 1 is a principle schematic of the present utility model; Fig. 2 is the three-view diagram of vacuum tube; Fig. 3 is the organigram of heat collector;

See Fig. 1--in 3, vacuum tube 8 is under the radiation of the sun, to the heating of the cold water in managing.The characteristic of utilizing hot water to rise, hot water behind the thermal-arrests is risen discharge and enter storage tank 2 tops through last collecting box 10 and heat collector delivery port 12 from vacuum tube 8 upper ends, the cold water of storage tank 2 bottoms enters through heat collector water inlet 11 and the lower end of following collecting box 9 by vacuum tube simultaneously, form Natural Circulation, progressively that the heating of the water in the storage tank 2 is for people to use.When triple valve 3 is in (a) position, be closed condition; When triple valve 3 was in (b) position, running water entered storage tank 2 through triple valve 3, under the tap water pressure effect, the hot water on storage tank 2 tops was ejected direct heating water; When triple valve 3 was in (c) position, a running water part entered storage tank 2, and a part is mixed with hot water outlet 16, supply temperature adjustment water.
