Abstract
The utility model relates to a heat preservation water tank for a water heater. Existing heat preservation water tanks or outer shells can be easily contracted and deformed, and the heat preservation effect is worse. Thereby the heat preservation water tank for the water heater comprises an outer shell and an inner container, a polyurethane foam plastic heat preservation layer with pantane as foaming agent is arranged between the outer shell and the inner container, and an insulating membrane is arranged between the polyurethane foam plastic heat preservation layer with pantane as foaming agent and the inner container. The heat preservation water tank for the water heater of the utility model has the advantages of simple structure and excellent heat preservation effect, the polyurethane foam plastic heat preservation layer with pantane as foaming agent is adopted, the ozone layer is not damaged, and the heat preservation water tank for the water heater is more environment-friendly, does not generate C1-, has long service life, and is widely applied in water heaters such as solar energy water heaters, electric water heaters, heat pump water heaters and the like.
Description
Technical field
The utility model relates to a kind of water heater attemperater.
Background technology
Water heaters such as solar water heater, electric heater and Teat pump boiler all need an attemperater, and existing attemperater comprises shell and inner bag, is provided with foam insulation between the two.Mostly this foam insulation is directly to foam between shell and inner bag to form.
After the foam insulation cooling was solidified, volume slightly shrank.Shell mostly is thin metal-back or plastic housing, is easy to be drawn distortion by this convergent force, influences attractive in appearance.
Under some situation, both made Enclosure Strength enough resist this contraction, and also can produce some other problemses: as foam insulation all or locally separate, even come off, influence heat insulation effect with inner bag.
The foam insulation that current attemperater adopts mostly is the polyurethane foam plastics heat-insulation layer, its blowing agent is HCFC-141b (a fluorine dichloroethanes) substantially, this material ODP value (depletion of the ozone layer index)=0.1 still has destruction to atmospheric ozone layer; And in the HCFC-141b molecular formula, contain chlorion (Cl
-), and solar water heater generally is in outdoor application, polyurethane foam is Cl under the condition that high temperature (about 100 ℃) makes moist
-Ion can generate watery hydrochloric acid (HCl), accelerates the corrosion of inner bag and shell, the water heater that has even just corroded bad in 1 year.
The utility model content
The technical problems to be solved in the utility model is the above-mentioned defective that how to overcome prior art, and a kind of water heater attemperater is provided.
For solving the problems of the technologies described above, this water heater attemperater, it is characterized in that: comprise shell and inner bag, being provided with between shell and the inner bag with the pentane is the polyurethane foam plastics heat-insulation layer of blowing agent, should be with the pentane be to be provided with barrier film between the polyurethane foam plastics heat-insulation layer of blowing agent and the shell.Wherein pentane comprises pentamethylene, isopentane or pentane.
So design, high insulating effect after attemperater is discarded, is convenient to peel off heat-insulation layer and inner bag, helps recycling.
ODP value=0 of pentane, employing are that the polyurethane foam plastics of blowing agent is made heat-insulation layer with the pentane, do not damage the ozone layer, more environmental protection; And do not produce Cl
-, long service life
As optimization, described barrier film is the flexible cellular plastic film, and thickness is 2～5mm.So design can play cushioning effect, after foam insulation shrinks, also can not produce cavity between itself and the shell, and is more attractive in appearance.
The utility model water heater has advantage simple in structure, high insulating effect with attemperater, and employing is that the polyurethane foam plastics of blowing agent is made heat-insulation layer with the pentane, do not damage the ozone layer, and environmental protection more, and do not produce Cl
-, long service life is widely used in water heaters such as solar water heater, electric heater and Teat pump boiler.
Description of drawings
Below in conjunction with accompanying drawing this water heater is described further with attemperater:
Fig. 1 is the cross-sectional structure schematic diagram of this water heater with attemperater.
Among the figure: 1 for shell, 2 for inner bag, 3 for being that the polyurethane foam plastics heat-insulation layer, 4 of blowing agent is a barrier film with the pentane.
The specific embodiment
Embodiment one: as shown in Figure 1, this water heater is drum shape with the attemperater profile, comprise shell 1 and inner bag 2, being provided with the pentane between shell 1 and the inner bag 2 is the polyurethane foam plastics heat-insulation layer 3 of blowing agent, and this is thought between the polyurethane foam plastics heat-insulation layer 3 of blowing agent and the inner bag 2 and is provided with barrier film 4.Described barrier film 4 is the flexible cellular plastic film, and thickness is 2～5mm.
Claims (2)
1. water heater attemperater, it is characterized in that: comprise shell and inner bag, being provided with between shell and the inner bag with the pentane is the polyurethane foam plastics heat-insulation layer of blowing agent, should be with the pentane be to be provided with barrier film between the polyurethane foam plastics heat-insulation layer of blowing agent and the inner bag.
2. water heater attemperater as claimed in claim 1 is characterized in that: described barrier film is the flexible cellular plastic film, and thickness is 2～5mm.
