Abstract

The utility model discloses a fixing frame for getters, which comprises a frame lower end and a frame upper end connected integrally with the frame lower end, wherein the frame lower end is welded with a round groove containing getters, the frame upper end is trapezium, the fixing frame is thick of 0.15-0.25mm, the upper bottom of the trapezium is thick of 3mm, the lower bottom is 8.7mm and the height is 5mm, the fixing frame is wide of 2mm, the frame lower end is welded with the round groove containing getters at two points. The getter fixing frame can confirm the success evaporation of barium, to improve the barium of the evaporated getter from 70% to 90%, thereby effectively improving the utilization of getters and improving the service life of vacuum solar heat collecting tubes.

Description

A kind of fixed support of getter

Technical field

The utility model relates to a kind of support, is specifically related to a kind of support that is used for fixing getter.

Background technology

The solar energy heat collection pipe of present domestic use, for guaranteeing the vacuum of vacuum interlayer in the solar energy heat collection pipe, in the vacuum interlayer of vacuum tube, evaporable air-absorbing agent is installed, getter is fixed on the stainless steel clamp, after the exhaust sealed-off, utilize high frequency to bake again and disappear, getter is discharged, form breathing film.Owing to the reason that stops of stainless steel clamp, the ubiquity getter gets the barium amount and can not reach scheduled target in the roasting process that disappears, and makes getter can not give full play to its effect, thereby has directly reduced the service life of vacuum heat collection pipe.Analyze getter in the roasting process that disappears, the distance between getter and the stainless steel clamp is too small, due to the product that partly evapotranspires is stopped.

Summary of the invention

The utility model provides a kind of and can fixedly secure getter in order to solve the deficiencies in the prior art, and deformation be difficult for to take place, and makes getter better steam the fixed support of getter of the air-breathing minute surface of loose, consistent and uniform in the roasting process that disappears.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of fixed support of getter, comprise support lower end and the support upper end that is connected as a single entity with the support lower end, the circular groove of described support lower end and placement getter is by being welded to connect, and described support upper end is trapezoidal.

Described support bracket fastened thickness is 0.15mm-0.25mm.

Described trapezoidal upper base is 3mm, goes to the bottom to be 8.7mm, and height is 5mm, and described support bracket fastened width is 2mm.

Described support lower end is welded to connect by two point with the circular groove of placing getter.

Compared with prior art, the utility model is by changing support bracket fastened shape of getter and Type of Welding, the fixed support deflection is controlled within two millimeters, and increase getter to distance between the clamp, guarantee to such an extent that the barium amount steams in the process of evapotranspiring smoothly, the barium amount that gets of nonevaporable getter agent is brought up to more than 90% by former 70%; Thereby effectively improve the utilization ratio of getter, the service life of having improved vacuum solar collector tubes.

Description of drawings

Fig. 1 is the utility model structural representation;

Fig. 2 is the structural representation of user mode of the present utility model;

Fig. 3 is the left view of Fig. 2.

Among the figure: 1 support lower end, 2 supports upper end, 3 grooves, 4 getters.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

Referring to Fig. 1, Fig. 2 and Fig. 3, a kind of fixed support of getter, supportlower end 1 is connected as a single entity with supportupper end 2, and supportlower end 1 adopts two point to be welded on thegroove 3, places getter 4 in thegroove 3, andgroove 3 is the clip slot of two circles, and supportupper end 2 is trapezoidal; Described support bracket fastened thickness is 0.15mm-0.25mm, and width is 2mm, and material is a stainless steel.

Described trapezoidal upper base is 3mm, goes to the bottom to be 8.7mm, and height is 5mm.

The fixed support of getter of the present utility model has fundamentally been avoided the inadequate present situation because the barium amount that gets that deformation of timbering causes is evapotranspired, and effectively improves the utilization ratio of getter, the service life of having improved complete glass vacuum sun thermal-collecting tube.

Above-described embodiment, the utility model specific embodiment a kind of more preferably just, the common variation that those skilled in the art carries out in the technical solutions of the utility model scope and replacing all should be included in the protection domain of the present utility model.

Claims (4)
