Abstract
The invention discloses a natural-circulation type water storage and heat exchange water tank, comprising a heat preservation water tank body. A heat preservation layer is arranged outside a liner of the heat preservation water tank body; the liner is an outer layer liner; an inner layer liner is further arranged inside the outer layer liner, so as to form a structure of an annular cavity of the two layer liners; a coil pipe is mounted in the annular cavity; a heat conduction medium is filled in a cavity of the inner layer liner; the inner layer liner is communicated with a first external heat source; the coil pipe is communicated with a second external heat source; the annular cavity between the two layer liners is used as a water storage and heat exchange space of living water; a tap water inlet and a hot water pipe outlet are arranged at the bottom of the annular cavity; and a hot water pipe extends at a top part of the annular cavity. The natural-circulation type water storage and heat exchange water tank provided by the invention overcomes defects of a conventional double-coil pipe, realizes no-power natural circulation of the liner, and reaches the energy conservation to the greatest extent. When the coil pipe is damaged, the coil pipe can be individually repaired without replacing the water tank.
Description
Technical field
The present invention relates to a kind of novel water storage heat-exchanger rig, specifically is that a kind of natural circulation mode and external heat source composition circulatory system utilized carried out the device that hot water was produced and stored in heat exchange.
Background technology
Combined type heat supply product in multipotency source is more and more at present.For example air source heat pump and solar energy combination heat supply water and gas-heating water heater and solar energy make up heat supply water, and its employed water storage heat-exchanging water tank is double plate and guarantees reservoir, can be divided into double plate pipe and two kinds of forms of inside and outside double plate pipe up and down substantially.
The water tank of double plate form of tubes structure is up and down: it is that upper and lower two groups of coil pipes are installed on condenser hot well liner; Its up and down the heat transfer process of two groups of coil pipes all be heat to be passed to inner bag and then with the water heat exchange through coil pipe, rather than through directly that water tank is the inner water heat exchange of inner bag.Go up in addition coil pipe in use since the effect of gravity can only heating water tank top sub-fraction water; And therefore the water of water tank middle and lower part still be cold water because of obtaining enough heats; The inner hot and cold water layering of water tank is apparent in view; So this type of water tank has not only prolonged heat transfer process in real life heat exchange efficiency is reduced, cause energy waste, more obviously cause result of use relatively poor because of the hot and cold water layering.
The water tank structure of inside and outside double plate form of tubes is: it is that one group of coil pipe is installed respectively in the outer wall of condenser hot well liner and inner chamber; Coil pipe heat transfer process on its outer wall also is through coil pipe heat to be passed to inner bag then with the water heat exchange, rather than through directly that water tank is the inner water heat exchange of inner bag.Though the water tank heat transfer process of the upper lower burrs tubing type that the water tank of this type is more top shortens to some extent, but still there is the low energy waste phenomenon of bringing of heating efficiency.
Therefore no matter be the water tank of upper lower burrs form of tubes or the water tank of internal and external disk form of tubes, all have obvious defects, heat exchange efficiency is not high, and result of use is bad.And for the water tank that outer coil pipe is arranged, in case outer coil pipe damage, can only the integral replacing water tank, can't repair coil pipe separately.Double plate pipe water tank all need increase extra water pump and carry out forced circulation in addition, these all can to the user bring the energy and economically waste.
Summary of the invention
The object of the invention is exactly in order to overcome the defective that above-mentioned existing water tank exists.Adopt a kind of brand new, natural recirculating type water storage heat-exchanging water tank that performance is better.
The object of the invention can be realized through following technical scheme:
A kind of natural recirculating type water storage heat-exchanging water tank, it comprises the attemperater body, the attemperater body is to be provided with heat-insulation layer outside the tank; It is characterized in that described inner bag is outer inner bag, also be provided with a nexine inner bag in the outer inner bag; Form the ring cavity structure of double-layer inner containers, coil pipe is installed in ring cavity; Be full of heat-conduction medium in the nexine internal bladder cavity, the nexine internal bladder cavity is connected with first external heat source, through the natural recirculating type heat exchange of heat-conduction medium realization with first external heat source; Coil pipe is connected with second external heat source, realizes and the second external heat source heat exchange through heat-conduction medium; Ring cavity between the double-layer inner containers is as the water storage heat transfer space of life water, and running water inlet and hot-water line outlet are established in the ring cavity bottom, and wherein hot-water line stretches into the ring cavity top, forms the Inlet and outlet water mode that cold water top backheat water is advanced in the bottom.
For stopping the generation of incrustation scale, the outer wall of above-mentioned nexine inner bag and the inwall of outer inner bag all are compounded with polymer material layer.
Above-mentioned attemperater body adopts the polyurethane insulation coating of 50mm thickness.
Good effect of the present invention is:
In externally two heat supplies, heat exchange area separately is big, the phenomenon that does not have diabatic process to prolong; The surface area of nexine inner bag all is a heat exchange area; No matter coil pipe can adopt any heat supply all by another thermal source heat exchange, all comes heat exchange with the shortest heat transfer process; Have higher heat exchange efficiency, do not have the phenomenon of thermal loss and energy waste.Overcome the drawback of existing double plate pipe.Realized the unpowered Natural Circulation of inner bag, reached energy-conservation to greatest extent, when coil pipe damages, can repair coil pipe separately, and need not to change water tank.Owing to begin heat exchange from water tank bottom, the water-cooled thermal stratification in the water tank more can not appear, obviously improved comfort.
Below in conjunction with accompanying drawing patent of the present invention is further specified.
