Description

The separated type solar water heater

The utility model relates to a kind of solar water heater, and particularly a kind of attemperater and plane skylight can be installed on indoor, outdoor solar water heater respectively.

Prior solar water heater is the integral installation structure, and promptly plane skylight and boiler are single unit systems, can only be installed on the roof.Its weak point one is because the high stratification of urban house, the roof erection space is restricted, the length and the installation difficulty of duct coupling have been strengthened, make the pipeline heat loss big, a water tank and a use point distance, adding water should not observe and control, thereby has limited the extensive use of solar water heater at the city high-rise residential building; The 2nd, anti-frost protection measure imperfection causes the frost heave damage accident easily in the use.

It is indoor, outdoor that the purpose of this utility model provides a kind of boiler and plane skylight to be installed on respectively at above-mentioned weak point exactly, and thermal losses is little, adds water and easily observe and control, is fit to the separated type solar water heater that high-rise residential building uses.

Technical solution of the present utility model is: a kind of separated type solar water heater, comprise attemperater and plane skylight, and it is characterized in that: plane skylight comprises heat-insulation layer, the snakelike heat pipe at middle part and the double-deck light-transmissive film on top of bottom.Be provided with the insulation connecting tube between upper and lower port of this snakelike heat pipe and the attemperater.

The lower port place of the snakelike heat pipe described in the technical solutions of the utility model can be provided with the automatic freezing-protective valve, this automatic freezing-protective valve comprises that its underpart is provided with the valve body that spilled water hole, top connect a drum shape temperature detector shell of being made by stainless steel material, the valve rod that cooperates with this spilled water hole, and the piston and the spring of this valve rod end connection.The temperature detector shell is provided with water injection hole.

The utility model is owing to be provided with the insulation connecting tube between attemperater and plane skylight, thereby plane skylight can be installed on the balcony or exterior wall of sunny slope, attemperater is installed in than under the slightly high toilet ceiling of plane skylight, so just, can shorten the length of connecting tube, heat loss is reduced significantly, also no longer take simultaneously the space on roof, make the solar energy equipment of city high-story house install more convenient, more flexible, observe when also being convenient to add water and control, make the utility model be adapted at applying of city high-story house.Because the utility model is provided with the automatic freezing-protective valve, can makes the solar energy equipment can be, thereby can eliminate the danger that frost heave is damaged automatically with the water emptying before freezing.The utility model plane skylight also can be installed on the roof, but attemperater must be installed in the top of plane skylight, to guarantee normal thermal cycle.The utility model has overcome the deficiencies in the prior art part, thereby has reached the purpose of this utility model.

The drawing of accompanying drawing is described as follows:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the A-A cutaway view of Fig. 1;

Fig. 3 is the sectional structure chart of automatic freezing-protective valve among Fig. 1.

The utility model is described in further detail below in conjunction with accompanying drawing: as shown in Figure 1 to Figure 3.Attemperater 1 is airtight non-pressure vessel, and spilling water air vent 3 is arranged at its top, and effect is exhaust and spilling water, and to guarantee the normal pressure circulation of system, circulation insulation connecting tube 9 is arranged at the bottom.The periphery of attemperater 1 is surrounded by insulation material 2 and protective case, and its installation site should be higher more than 0.5 meter than plane skylight 7.

Plane skylight 7 is made up of double thermal insulation light-transmissive film 10, extinction heat preservation layer 11 and snakelike heat pipe 8.Double thermal insulation light-transmissive film 10 adopts the mylar of high transmission rate to make, utilize double-decker to form the gas thermofin to strengthen heat insulation effect, reduce the heat loss of daylighting face, extinction heat preservation layer 11 adopts foamed plastics and the higher titanium dioxide (TiO of photo-thermal conversion efficiency ₂) the blacking brushing that forms of modulation forms.When solar radiation, black light-absorbing coating can make the plane skylight inner chamber generate heat fast.Snakelike heat pipe 8 is coiled to form for heat transfer good conductor single tube, constitutes the unbalanced heat collecting structure, to increase the water-in and water-out temperature difference, accelerates water circulating speed, improves thermal conversion efficiency.

Automatic freezing-protective valve 6 is fixed between snakelike heat pipe 8 lower port and the insulation connecting tube 9, and effect is to guarantee to open water in the frost valve emptying system before system freezes, and prevents the frost heave damage.Temperature detector shell 17 is stainless piston sleeve, piston 13 usefulness nuts connect valve rod 16, and under the non-temperature that freezes, spring 14 promotes to move on the piston 13 closes valve rod 16, cross flowing water and use by valve body 15, the superjacent air space of piston 13 is by water injection hole 12 filled with potable water and sealing.When reaching solidification point, because temperature detector shell 17 is different with valve body 15 material therefors, 17 heat conduction of temperature detector shell are fast, at first freeze, and valve body 15 heat conduction are slow, add the temperature action of flowing water, and the speed that freezes is slower than the water filling in the temperature-sensitive chamber.When the water filling in the temperature-sensitive chamber is freezed, volumetric expansion, the pressure promotion piston 13 that overcomes spring 14 is descending, will cross flowing water by the spilled water hole emptying thereby open valve rod 16, thereby realizes preventing the purpose of plane skylight frost heave damage.Automatic freezing-protective valve 6 also can be used for the antifreeze of automobile, tractor.

When cold water through water supply valve 5 after attemperater 1 filling because the position of attemperater 1 is higher than plane skylight 7, cold water fills the inner chamber of snakelike heat pipes 8 through insulation connecting tube 9.When solar radiation, sunlight sees through double-deck light-transmissive film 10 and shines on extinction heat preservation layer 11 and snakelike heat pipe 8, the temperature rising that black light-absorbing coating at first generates heat and makes plane skylight 7 inner chambers, heat is passed to cold water by snakelike heat pipe 8, when cold water is heated, volume increases, proportion diminishes, effect float downward at cold water, because the effect of the compound integration heating of coiled pipe, the hot water of come-up is further heated and the speed of quickening come-up, and, bring heat energy into the water tank deposit by insulation connecting tube 9 formation circulating water flows.Because the temperature difference of entery and delivery port exists all the time, no matter how high the temperature of water tank is, as long as the endothermic temperature of plane skylight 7 is not less than the temperature in the water tank, thermal cycle just can be carried out again and again, and therefore water temperature progressively raises.During use, open hot water valve 4 and get final product bathing, when temperature is too high, can suitably opens water supply valve 5 and be adjusted to proper temperature.
