Description of drawings
Fig. 1 is a structural system schematic diagram of the present utility model.
Fig. 2 is the schematic diagram of another embodiment of second heater of the present utility model.
The specific embodiment
For further understanding technical characterictic of the present utility model and content, be elaborated below in conjunction with accompanying drawing.Seeing also Fig. 1, is example with automatic internal-circulation type solar water heater, and the utility model comprises: be installed on outdoor solar energy system 1 and second heater 2 that is installed in the kitchen range chamber, be connected by high-temperature conduit 31 and low temperature water pipe 32 respectively between the two.
Wherein, second heater 2 is a heat build-up pipe 20, and heat build-up pipe 20 is the mini diameter tube of hollow, the vertical wraparound curl, and two ends are respectively delivery port 201 and water inlet 202.Its delivery port 201 is higher than water inlet 202, and it is poor to form certain height.The external diameter of pipe of heat build-up pipe 20 is 27mm ± 5mm, wall thickness 〉=0.5mm; The conveyor screw external diameter that encompasses is 420mm or 360mm, and pitch is 70mm, and the number of turns is 2 circles; Go out, the difference in height between the water inlet is 50-70mm; Material is the good red copper of thermal conduction effect.Understandable, heat build-up pipe 20 also can be flat tube or other shape tube.And with it around being helical form, be in order to cooperate the shape of kitchen range chamber and pot, convenient settle and use, therefore, the spirochetal size and the number of turns can decide according to the shape in kitchen range chamber, and be so that it is looped around the periphery in the bottom of a pan, close but not contact the bottom of a pan be preferable.The material of heat build-up pipe 20 also can be selected the good material of other thermal conduction effect for use.
Solar energy system 1 comprises storage tank 10 and heat collector 11.Wherein, storage tank 10 is a cylindrical tube shape, partly is made up of shell, inner bag and the filler between the two etc.Its structure, technology are identical substantially with the storage tank of existing solar water heater.The bottom side of storage tank 10 is provided with hot water mouth 101 and cold water outlet 102, and wherein, hot water mouth 101 is higher than cold water outlet 102, and it is poor to form certain height.Preferable, cold water outlet 102 is equal substantially with the inner bag of water tank bottom surface; Hot water mouth 101 is by the high water tank of vertical tube bottom surface 30-50mm.Top near storage tank 10 is provided with overfall 103, and overfall 103 is connected with the vertical tube 104 of storage tank 10 outsides.The bottom sealing of vertical tube 104, the top communicates with atmosphere, is used for exhaust and overflow, and makes the water in the storage tank 10 keep atmospheric pressure state.The inner bag of storage tank 10 and the distance between the shell are 55mm ± 5mm, and inner bag is that the stainless steel of SUS304-2B is made by model, and shell is made by aluminium plating zinc plate, and filler is a Polyurethane machinery pressure expansion, so that water tank has heat insulation function preferably.
The structure of heat collector 11 and principle are identical with the heat collector of general now solar water heater, do not repeat them here.
Second heater 2 is installed in the kitchen range chamber of the family expenses kitchen range top, makes heat build-up pipe 20 be looped around the periphery in the bottom of a pan, near but do not contact the bottom of a pan.Solar energy system 1 is installed in outdoor sun-drenched position, generally is installed on the sunny side roof.The delivery port 201 of heat build-up pipe 20 is connected by high-temperature conduit 31 with the hot water mouth 101 of storage tank 10; Water inlet 202 is connected by low temperature water pipe 32 with cold water outlet 102.The hot water mouth's 101 of storage tank 10 vertical height is higher than the vertical height of the delivery port 201 of heat build-up pipe 20, and is preferable, and vertical range is 2.8 meters-12 meters.Be connected with a threeway 33 on the low temperature water pipe 32, an outlet of threeway 33 connects hot water valve 34, and leads to discharging device, as shower nozzle; Another outlet connects cold valves 35, and leads to water supply installation, and water supply installation can be running water or family expenses water tower.
Current, the kitchen range top that China generally uses in the rural area is fuel saving stove, and fuel saving stove is when normally cooking, and the temperature in the kitchen range chamber can reach about 700 ℃.Second heater 2 that is installed in the kitchen range chamber is always constantly absorbing the heat energy that distributes with heat radiation, conduction, convection type in the kitchen range chamber, and then make water expanded by heating in the heat build-up pipe 20, density diminishes and floats, because the delivery port 201 of heat build-up pipe 20 is higher than water inlet 202, and the water temperature on heat build-up pipe 20 tops is higher than the water temperature in the storage tank 10, so the hot water in the heat build-up pipe 20 is entered in the storage tank 10 by hot water mouth 101 along high-temperature conduit 31 by delivery port 201.The relatively low water of temperature in the water tank, because of density is sunk greatly, cold water outlet 102 by water tank bottom comes downwards to temperature lower low temperature water pipe 32 relatively, and until the water inlet 202 of heat build-up pipe 20, thereby the heat energy that has formed to scatter and disappear in the kitchen range chamber is the automatic internal circulation system of the water of thermal source.As long as in the kitchen range chamber thermal source is arranged, the most of heat energy that scatters and disappears in the kitchen range chamber can be transported in the storage tank 10 by water continuously, and when the heat energy in the input storage tank 10 equated with its heat energy that is scattered and disappeared, the water in the storage tank 10 reached dynamic thermal balance.When need use hot water, open hot water valve 34, the hot water in the storage tank 10 will flow out by low temperature water pipe 32, regulates the cold valves 35 that links to each other with water supply installation simultaneously, just can obtain the suitable hot water of temperature.
See also Fig. 2, be another embodiment of second heater of the present utility model, the difference of itself and a last embodiment is the shape difference of heat build-up pipe 20 '.In the present embodiment, heat build-up pipe 20 ' comprises that two are in charge of, and is in charge of hierarchal arrangement in vertical direction, and every is in charge of the shape that all is bent into more than half annulus on horizontal direction.Be in charge of at the both ends of annulus for two and be interconnected, wherein, that the wherein end from annulus that is in the upper strata extends certain-length and forms the mouth of a river 201 '; Be formed into the mouth of a river 202 ' and that other end from annulus of lower floor extends certain-length, thereby use, form difference in height between the water inlet.Understandable, be in charge of also and can be many; The heat build-up pipe also can adopt other shape; Even second heater except that the heat build-up pipe, also can establish other thermal-arrest structures, be extended with heat absorbing sheet etc. laterally as outer wall from the heat build-up pipe.
The above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also carry out some improvement and modification to the utility model, these improvement and modification also fall in the protection domain of the utility model claim.
