Abstract

The utility model discloses a solar water heater which comprises a water storage tank, wherein a plastic liner is arranged in the water storage tank, a heat-collecting hole is arranged on the liner body of the plastic liner, and an insulation layer is arranged outside the plastic liner. The solar water heater is characterized in that the axial outer surface of the liner body of the plastic liner is provided with cross breaks. Because the axial outer surface of the liner body of the plastic liner is provided with the cross breaks, the utility model not only can prevent the liner from axially expanding and shrinking when temperature changes and ensure the reliability of connection between the liner and a pipeline, and the like, but also takes the effect of strengthening ribs and enhances the capability of the plastic liner for bearing external force.

Description

Solar water heater

Technical field

The utility model relates to a kind of solar water heater, relate in particular to a kind of solar water heater with plastics inner bag.

Background technology

At present, generally adopt the plastics inner bag in the solar water heater.The courage body of common plastics inner bag is generally planarized structure, and it can't bear from the external force effect in transportation and the heat-insulating layer foaming process, deform easily, and it is difficult for fixing in foaming layer; The vacuum pore place of courage body is yielding or be subjected to displacement during superhigh temperature; The thickness of its thermal-arrest mouth is how identical with the courage body thickness, intensity difference, and the long-time back thermal-arrest mouth easy deformation of using, its size easily changes after changing wind-collecting pipe especially, causes the courage body to use.

The utility model content

The purpose of this utility model is: at the deficiency that prior art exists, provide a kind of inner bag intensity height, not yielding and inner bag easy fixing solar water heater in foaming layer.

The utility model is achieved by the following technical solution: a kind of solar water heater, comprise its storage tank, be provided with the plastics inner bag of band thermal-arrest mouth on the courage body in the storage tank, inner bag is provided with heat-insulation layer outward, and the courage external surface of described plastics inner bag has tortuous line.

The utility model designs tortuous line by the courage external surface at the plastics inner bag, on the one hand absorb inner bag because elongation or the contraction on the length direction that temperature produces when changing by it, these tortuous lines form reinforcement again on the other hand, the courage body is carried out structural reinforcement, the reinforced plastics inner bag bears the ability of external force, guarantee phenomenons such as the vacuum pore is not subjected to displacement, distortion, thereby guarantee the reliability of vacuum pore place sealing.

In order to guarantee plastics inner bag fixing in heat-insulation layer, the heat-insulation layer inner surface be provided with plastics inner bag outer surface on the curved surface of tortuous line corresponding matching, its mating surface is radially leaving the gap.This kind design makes the inner surface of heat-insulation layer and the courage external surface can be engaged, not only can be simultaneously the harmomegathus of plastics inner bag length direction be further limited, in use axial length is constant or change little purpose to reach inner bag, and guarantee itself and the reliability that is connected of pipeline etc., can not cause getting loose because of variations in temperature.

The axial cross section of described tortuous line can be undaform or semicircle camber or W type or V-type.

Described tortuous line can also be I type or S type on the axial external surface of courage body.

For the solar energy inner bag in use can be born because the stress that produces during variations in temperature, subduction vacuum pore place is subjected to stress, guarantee that vacuum pore place is smooth indeformable, the utility model the courage external surface be provided with at least one along the courage axon to reinforcement.The distortion that the week that this reinforcement produces in the time of absorbing the courage body because of variations in temperature makes progress prevents that courage body and thermal-arrest mouth place thereof from deforming.This reinforcement can be to courage body sunken inside, also can be to the external projection of courage, and its cross section can be circular arc or V-arrangement or other shape, when courage body Yin Wendu changes when producing circumferential distortion, can absorb distortion by extruding or this reinforcement that stretches, guarantee that the thermal-arrest mouth place of courage body does not deform.In order to improve the ability of the whole resistance to deformation of courage body, this reinforcement can extend to two end faces of courage body to both sides, and two the end faces formation reinforcement radially at the courage body makes the courage physical efficiency bear the stress of all directions, improves the ability of the whole resistance to deformation of courage body.Consider processing technology and result of use, this reinforcement can be made as at four that certain intervals is upwards arranged in courage body week.

In order to improve the intensity at thermal-arrest mouth place on the courage body, the utility model is a wall thickness greater than the courage body with the Thickness Design of thermal-arrest mouth, and the thickness by increasing the thermal-arrest mouth makes it in use be difficult for deforming as reinforcement.It can also be designed to courage body inner process, its axial cross section is the notch cuttype of one deck at least, and its outboard end has been worn concave station as seam, and this species stage type design can be played the effect of reinforcing steel.The contact area of thermal-arrest mouth and thermal-collecting tube sealing ring is increased, effectively prevent the seepage phenomenon at thermal-arrest mouth place.

Make for convenience and assembling, described plastics courage body is formed in one.

The utility model has been owing to adopted the courage external surface to have the plastics inner bag of tortuous line, strengthened the ability that the plastics inner bag bears external force, reduced the stress deformation of plastics inner bags and in axial harmomegathus; Since the heat-insulation layer inner surface be provided with plastics inner bag outer surface on the curved surface of tortuous line corresponding matching, further limited the harmomegathus of plastics inner bag at length direction, guaranteed itself and the reliability that is connected of pipeline etc.; Secondly, at courage external surface setting reinforcement vertically, harmomegathus on the length direction that produces when the stress of all directions that produce when making the solar energy inner bag in use can bear and absorption variations in temperature owing to variations in temperature, guarantee vacuum pore place smooth indeformable, be not subjected to displacement, guarantee vacuum pore place ne-leakage possibility, improved the performance of water heater and prolonged its service life.
