Abstract
The invention discloses a heat storage water tank. The water tank is characterized in that a heating liner is arranged inside a water tank; phase change heat storage media with melting points being 50 DEG C are filled in a jacket of the water tank; and media with boiling points being about 30 DEG C are filled in the heating liner. By adopting the design, the circulation speed of heat-conducting media can be increased, the speed of heat exchange between a solar heat collector and the water tank can be increased, and when the hot water temperature is higher than 50 DEG C, heat storage materials store plenty of heat absorbed from hot water; and when the water temperature decreases, the heat storage materials release heat to stabilize the water temperature at about 50 DEG C.
Description
Technical field
The present invention relates to solar energy utilization technique and phase-change thermal storage technology, refer in particular to a kind of heat storage water tank for solar water heater, this water tank inside is provided with a heating inner container, and the phase-change thermal storage medium is housed in the water tank chuck.
Background technology
At solar energy heat utilization field, the multiple matured product of vacuum tube water heater and flat water heater has appearred comprising in solar water heater, and the plate type solar water heater is opened up markets rapidly with its longer service life and easy installation method.Flat plate solar water heater uses the mode of indirect more, because heat-conducting medium compares thickness, heating inner container or the design of chuck shape are unreasonable, cause heat transfer efficiency not high.And the solar water heater use is subject to weather and restriction round the clock easily.
At present existing a plurality of patents about solar water heater water tank, but can use liquid anti-icing fluid not yet to find as heat-conducting medium and the horizontal water-heater water tank in water tank inside of heating inner container.Below list several existing Patents:
(application number: 99229690.0) propose a kind of solar water heater water tank, its inner water tank is divided into two parts that do not communicate by water-stop sheet to patent " novel solar water heater water tank ", and conducts heat by water-stop sheet.
(application number: 200720037641.X) propose a kind of solar water heater water tank, this device is provided with an inner bag to patent " novel solar water heater water tank " in water tank, pure water is housed as heat transfer medium in the inner bag, the drinking water of heating water tank outside.
Summary of the invention
For heat collectors for solar water heater and water tank heat transfer rate and for water tank increases heat storage function, store unnecessary solar energy on daytime, be water tank night and additional heat when cloudy, the present invention proposes following technical scheme:
The present invention proposes a kind of heat storage water tank, and its structure comprises: insulation shell, water storage cavity, heat accumulation chamber, delivery port, water inlet, end cap, heating inner container, feed tube, return duct.Insulation shell adopts the polyurethane foam material insulation.Water storage cavity and heat accumulation chamber are surrounded by stainless steel material, and the heat accumulation chamber is trapped among the outside of water storage cavity, and inside, heat accumulation chamber is filled with fusing point at 50 ℃ phase-change heat-storage material, and water storage cavity inside is provided with a heating inner container.Domestic water is stored in the water storage cavity, and water inlet is near the water storage cavity top, and delivery port guarantees that near the water storage cavity bottom cold water enters from the bottom, and hot water is discharged from top.Heating inner container is the thin-wall stainless steel welding, and inside is filled with the heat-conducting medium of boiling point about 30 ℃, and is connected with flat-plate solar collector by feed tube and return duct, and the feed tube mouth of pipe is near the heating inner container top, and the return duct mouth of pipe is near the heating inner container bottom.End cap seal prevents from leaking at the oral area of water storage cavity.
Adopt this project organization, can improve the inadequate weakness of existing jacket type water tank media for heat exchange, and increased heat storage function for water tank, heat accumulating heat absorption when water temperature is higher than 50 ℃, heat accumulating heat release when being lower than 50 ℃, make water temperature stability about 50 ℃, reduced when cloudy day and night, solar energy can not utilize the impact on hot water.
Description of drawings
Below in conjunction with accompanying drawing, the invention will be further described.
Fig. 1 is the generalized section of this device.
The position of marking is respectively among the figure: 1, insulation shell; 2, heat accumulation chamber; 3, water storage cavity; 4, end cap; 5, delivery port; 6, feed tube; 7, heating inner container; 8, return duct; 9, water inlet.
The specific embodiment
Below in conjunction with accompanying drawing, embodiments of the present invention are described further.
The heat storage water tank outside is connected to flat-plate solar collector, and 2 inside, heat accumulation chamber are filled with phase-change heat-storage material, and heating inner container 7 inside are filled with lower boiling heat-conducting medium, and heat-conducting medium flows into the flat-plate solar collector heat absorption from return duct 8.The heat-conducting medium that heats up after vaporizing enters heating inner container 7 from feed tube 6, and heat release liquefaction in heating inner container 7.Water in the water storage cavity 3 heats up from heating inner container 7 absorbing heats.Heat-conducting medium after the liquefaction is back to flat-plate solar collector from return duct 8.When water temperature surpasses 50 ℃, the phase-change heat-storage material in the heat accumulation chamber 2 from hot water absorb amount of heat and store.When bad or night, water temperature reduced when sunlight, heat accumulating underwent phase transition heat release, kept water temperature stability about 50 ℃.
