Abstract

This application discloses a kind of vacuum multi-layer solar pipe, outer tube that the vacuum multi-layer solar pipe includes being sequentially communicated within outer, inner tube and several be provided with the built-in pipe of annular protrusion；It is vacuum sealing environment that the outer tube, inner tube, which connect space in the pipe to be formed with built-in pipe,；The lower end of the vacuum multi-layer solar pipe is provided with the first spring clip, and upper end is provided with second spring clamp.The application is novel in design, effect promoting is obvious, the application of multiple built-in pipes with annular protrusion make it that sunshine absorption area is effectively increased, hollow built-in pipe causes the inner pipe volume of solar energy heat collection pipe to reduce simultaneously, the volume of the water stored in inner tube reduces, so that heating is more rapid, the demand of user's instant-heating can be met；And the external dimensional standard of the application is general, it is adapted to the supporting and upgrading of existing water heater；And simple for structure, good manufacturability, easily implement, with very strong practicality.

Description

A kind of vacuum multi-layer solar pipe

Technical field

The utility model is related to solar energy vacuum tube technical field, and in particular to a kind of vacuum multi-layer solar pipe.

Background technology

Solar water heater is widely used at present, is given people life and is brought many convenience and material benefit, but existing There is also problems in real operation, such as need that water heater heating unhappy, temperature just occurs during hot water in use Not high the problems such as, it can not meet the demand that user i.e. need to be i.e. to hot water.Remove in the influence of weather reason, solar water heater Core component-vacuous solar energy pipe also there is the space that further optimizes, at present using most solar vacuum heat-collecting pipes Its only one undertake extinction function inner tube, profile is not reasonable, and outer surface is only cylinder smooth surface, and extinction area is small and interior The water disposably entered in pipe is more, it is impossible to realize speed heat.

Utility model content

For problems of the prior art, the purpose of this utility model is that providing a kind of heating in vacuum pipe may be reversed Solar heater, it efficiently solves problem present in background technology.

To achieve the above object, the utility model uses following technical scheme：

A kind of vacuum multi-layer solar pipe, outer tube that the vacuum multi-layer solar pipe includes being sequentially communicated within outer, Inner tube is provided with the built-in pipe of annular protrusion with several；The outer tube, inner tube connect space in the pipe to be formed with built-in pipe Vacuum sealing environment；The lower end of the vacuum multi-layer solar pipe is provided with the first spring clip, and upper end is provided with second spring Clamp.

Further, the body of the built-in pipe is straight tube, elliptical tube or twisted tube.

Further, it is coated with coating for selective absorption on said inner tube outer wall.

Further, it is coated with coating for selective absorption on the built-in inside pipe wall.

Further, it is provided with first spring clip in getter groove, the getter groove and is provided with air-breathing Agent.

Further, elastic circular ring and elastic circular ring hangs muscle are provided with the second spring clamp；The elastic circular ring It is connected by the elastic circular ring hangs muscle with second spring clamp.

Further, the elastic circular ring is arranged between the adjacent built-in pipe.

The utility model has following advantageous effects：

Vacuum multi-layer solar pipe of the present utility model is novel in design, and effect promoting is substantially, multiple with annular protrusion The application of built-in pipe make it that sunshine absorption area is effectively increased, while hollow built-in pipe causes solar energy heat collection pipe Inner pipe volume reduces, and the volume of the water stored in inner tube reduces, so that heating is more rapid, can meet user and open I.e. hot demand, eliminates the longer latency for waiting hot water, and the application of dual spring clamp and elastic circular ring is effectively buffered Cause the thermal stress of vacuum heat collection pipe open end during water heater working, it is to avoid the device damage brought by thermal stress；In addition, The external dimensional standard of the application is general, is adapted to the supporting and upgrading of existing water heater；And simple for structure, good manufacturability, hold Easily implement, with very strong practicality.

Brief description of the drawings

Fig. 1 is the diagrammatic cross-section of embodiment of the present utility model；

Embodiment

Below, refer to the attached drawing, is more fully illustrated to the utility model, is shown shown in the drawings of of the present utility model Example property embodiment.However, the utility model can be presented as a variety of multi-forms, it is not construed as being confined to what is described here Exemplary embodiment.And these embodiments are to provide, so that the utility model is fully and completely, and will be of the present utility model Scope fully conveys to one of ordinary skill in the art.

For ease of explanation, space relative terms such as " on ", " under " " left side " " right sides " can be used herein, for saying The element or feature shown in bright figure is relative to another element or the relation of feature.It should be understood that except in figure Outside the orientation shown, spatial terminology is intended to include the different azimuth of device in use or operation.If for example, in figure Device is squeezed, be stated as being located at other elements or feature " under " element will be located into other elements or feature " on ".Cause This, exemplary term " under " both upper and lower orientation can be included.Device, which can be positioned otherwise, (to be rotated by 90 ° or is located at Other orientation), can correspondingly it be explained used herein of the relative explanation in space.

As shown in Figure 1-2, this application provides a kind of vacuum multi-layer solar pipe, the vacuum multi-layer solar pipe include from The outer tube 1 that is sequentially communicated within outer, inner tube 2 and several be provided with the built-in pipe 4 of annular protrusion 3；Outer tube 1, inner tube 2 and built-in Space is vacuum sealing environment in the pipe that the connection of pipe 4 is formed；The lower end of vacuum multi-layer solar pipe is provided with the first spring clip 5, upper end is provided with second spring clamp 6.

The body of built-in pipe 4 is straight tube, elliptical tube or twisted tube.

Coating for selective absorption is coated with the outer wall of inner tube 2.

Coating for selective absorption is coated with the inwall of built-in pipe 4；Selective absorbing on the outer wall of inner tube 2 can be absorbed on a small quantity to apply Layer is without the luminous energy all absorbed.

It is provided with first spring clip 5 in getter groove 7, getter groove 7 and is provided with getter, for keeps outer High vacuum environment inside pipe 1, inner tube 2 and built-in pipe 4.

Elastic circular ring 8 and elastic circular ring hangs muscle 9 are provided with second spring clamp 6；Elastic circular ring 8 passes through elastic circular ring Hangs muscle 9 is connected with second spring clamp 6.
