The solar water container of novel liner of jacket structure
Technical field
The utility model relates to a kind of solar water container, especially relates to a kind of solar water container of novel liner of jacket structure.
Background technology
Along with popularizing of solar water heater, the user is more and more higher to the functional requirement of water heater.The solar water container of prior art, its structure generally comprises shell, water inlet pipe and water outlet pipe, heat exchanger and inner bag.This water tank also can carry out medium circulation by the heat exchanger in the water tank except adopting electrical heating, thereby improves the heat exchange effect of water tank.At present, the heat exchanger that has adopts the version of inner bag chuck, and the inner bag chuck is made up of outer layer barrel and internal layer cylinder, and medium circulates between outer layer barrel and internal layer cylinder.But, the inner bag chuck of existing this structure, when welding with liner end enclosure, because pad is closer apart from the internal layer cylinder of inner bag chuck, the radiations heat energy of welding exerts an influence to the enamel layer of internal layer cylinder inboard wall, time one is long, and the enamel layer of internal layer cylinder inwall can peel off, thereby influences the service life of water tank.
Summary of the invention
The technical problems to be solved in the utility model provides and a kind ofly can reduce the solar water container that enamel layer is welded the novel liner of jacket structure of radiation effect.
Technical problem to be solved in the utility model is achieved by the following technical solution: it comprises the inner bag chuck of shell, water inlet pipe and water outlet pipe, medium circulation mouth, liner end enclosure and annular, the inner bag chuck is made up of outer layer barrel and internal layer cylinder, internal layer cylinder and liner end enclosure welding are fixing, between outer layer barrel and liner end enclosure, be provided with hoop, hoop is weldingly fixed on the liner end enclosure, and outer layer barrel and hoop welding are fixing.
The said structure that the utility model adopts, owing between outer layer barrel and liner end enclosure, be provided with hoop, hoop is weldingly fixed on the liner end enclosure, outer layer barrel and hoop welding are fixing, pad is away from the internal layer cylinder of inner bag chuck, avoided of the influence of welding radiations heat energy, thereby can prolong the durable life-span of water tank enamel layer internal layer cylinder inboard wall enamel layer.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further:
Figure 1 shows that structural representation of the present utility model
Figure 2 shows that the partial enlarged drawing at B place among Fig. 1
The specific embodiment
By accompanying drawing as can be known, the solar water container of this novel liner of jacket structure comprises the inner bag chuck of shell, water inlet pipe and water outlet pipe, medium circulation mouth, liner end enclosure 3 and annular, the inner bag chuck is made up of outer layer barrel 1 and internal layer cylinder 2, internal layer cylinder 2 is fixing with liner end enclosure 3 welding, between outer layer barrel 1 and liner end enclosure 3, be provided with hoop 4, hoop 4 is weldingly fixed on the liner end enclosure 3, and outer layer barrel 1 is fixing with hoop 4 welding.When welding fixedly with hoop 4 outer layer barrel 1, pad has been avoided the harmful effect of welding radiations heat energy to internal layer cylinder inboard wall enamel layer as shown in Figure 2 away from the internal layer cylinder of inner bag chuck.During work, add circulatory mediator (oil, water, alcohol, anti-icing fluid etc.) from the medium liquid feeding mouth, circulatory mediator in the solar thermal collector is delivered to the inner bag chuck by the medium circulation mouth with heat, by the inner bag chuck heat is passed to water in the inner water tank main body again, thereby reaches the purpose that adds hot water.The utility model is with the described scope of soverlay technique scheme; and the various modification of claim scope and equivalence variation; under the prerequisite that does not depart from technical solution of the present utility model, any modification or improvement that those skilled in the art that the utility model is done realize easily all belong to the utility model scope required for protection.
