Description
Technical field
The utility model relates to owner's thermal-collecting tube, especially a kind of metal vacuum thermal-collecting tube.
Background technology
Thermal-collecting tube is the critical component in a kind of solar thermal collector, compound glass thermal-collecting tube, collector metal pipe is generally arranged and by glass and the compound metal vacuum thermal-collecting tube of metal tube.In the metal vacuum thermal-collecting tube of reporting at present, generally formed by glass outer tube, outward flange, bellows, inner flange, metal inner pipe.Metal inner pipe runs through the glass outer tube, add man-hour, with glass outer tube end, inner flange, bellows, outward flange, the metal inner pipe outer wall is welded seal in proper order, in the glass outer tube, form vacuum chamber, solar energy sees through the glass outer tube and arrives at metal inner pipe in the vacuum chamber, heating agent in the metal inner pipe is carried out heat exchange, this thermal-collecting tube, solved preferably the axial stretching difference that two kinds of different materials that glass outer tube and metal inner pipe use exist when the variations in temperature by bellows, but because bellows has deformable character, in the process that telescopic variation occurs, will inevitably cause the concentricity between glass outer tube and the metal inner pipe to change, when serious even can directly contact with the glass outer tube at metal inner pipe under the condition of high temperature, directly affect the heat insulation effect of metal vacuum thermal-collecting tube.
The utility model content
The purpose of this utility model is, for the concentricity that can change after the ripple pipe generation telescopic variation of existing metal vacuum thermal-collecting tube existence between glass outer tube and the metal inner pipe, change the practical problem of the duty of metal vacuum thermal-collecting tube, a kind of new metal vacuum thermal-collecting tube is provided.
The purpose of this utility model is achieved in that a kind of metal vacuum thermal-collecting tube, comprise the glass outer tube, run through the metal inner pipe of glass outer tube and the flange component at glass outer tube two ends, flange component contains two ring flanges and bellows, two ring flanges are positioned at the bellows two ends and are tightly connected with corrugated tube end, glass outer tube two ends by flange component with after the metal inner pipe outer wall is connected, in the glass outer tube, form vacuum chamber, it is characterized in that: the opposite face of two ring flanges of described flange component is provided with the support set of concentric, support set on one of them ring flange is the outer support cover, support set on another ring flange is the inner support cover, behind the inside and outside support set suit and the axle center of glass outer tube and metal inner pipe is overlapping, and they are followed bellows to stretch and slide; Described metal inner pipe is suspended in the inner support cover.
In the utility model: described outer support cover is arranged in concentric bellows, or bellows is arranged in concentric inner support cover.
In the utility model: the support set on the ring flange that is tightly connected with glass outer tube end is the outer support cover, and the support set on the ring flange that is tightly connected with the metal inner pipe outer wall is the inner support cover.
In the utility model: the support set on the ring flange that is tightly connected with glass outer tube end is the inner support cover, and the support set on the ring flange that is tightly connected with the metal inner pipe outer wall is the outer support cover.
The utility model has the advantage of, compact conformation of the present invention, owing to being provided with respectively an outer support cover and inner support cover at a pair of ring flange that is tightly connected with glass tube and metal inner pipe, overlapping with one heart behind the inside and outside support set suit, and in the flexible scope slip of bellows, under the internal diameter that external diameter and the outer support of inner support cover are overlapped is fitted to each other support, can effectively prevent from or reduce after the bellows telescopic variation impact of glass tube and metal inner pipe concentricity is guaranteed that the metal vacuum thermal-collecting tube is in the optimum Working of design all the time.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Among the figure: 1, metal inner pipe, 2, ring flange, 3, bellows, 4, ring flange, 5, the glass outer tube, 6, the inner support cover, 7, the outer support cover, 8, vacuum chamber.
The specific embodiment
Accompanying drawing discloses the concrete structure of the utility model embodiment without limitation, below in conjunction with accompanying drawing the utility model is done to describe further.
As seen from Figure 1, the metal vacuum thermal-collecting tube comprises glass outer tube 5, runs through the metal inner pipe 1 of glass outer tube 5 and the flange component at glass outer tube 5 two ends, flange component contains ring flange 2 and ring flange 4 and bellows 3, ring flange 2 is connected with ring flange and is positioned at bellows 3 two ends and is connected with bellows 3 end part seals, glass outer tube 5 two ends by flange component with after metal inner pipe 1 is connected, at glass outer tube 5 interior formation vacuum chambers 8.Be provided with the support set of concentric at the opposite face of ring flange 2 and ring flange 4, support set on one of them ring flange is outer support cover 7, support set on another ring flange is inner support cover 6, behind the inside and outside support set suit and the axle center of glass outer tube 5 and metal inner pipe 1 is overlapping, when variations in temperature caused that difference appears in glass outer tube 5 and metal inner pipe 1 range of expansion, inside and outside support set can be followed bellows 3 telescopic variation and slide.Simultaneously, metal inner pipe 1 is suspended in the inner support cover 6 all the time.
