As improvement, the flexure strip that the two ends of described glass outer tube can be respectively arranged with energy axial stretching is connected with the interior seal of tube.
As improvement, one end flexure strip of described glass outer tube and inner tube can be preferably the coiling sheet that axial section is " shear wave shape ", and described coiling sheet is mutually sealed glass outer tube and inner tube to be fixed together by welding.
Improve again, the other end flexure strip of described glass outer tube and inner tube may be selected to be the little circular cone sheet broad in the middle in two, described inner tube is through circular cone sheet middle part, and two inwall of described circular cone sheet is connected with the outer wall sealing of inner tube by welding, and one end of described circular cone sheet is connected with metal cover sealing, and the circumference bottom surface of described metal cover is together with the periphery seal welding of one end of glass outer tube.
As improvement, in described glass outer tube and be positioned at inner tube bottom and also can be provided with reflector layer.
As improvement, described reflector layer may be selected to be the figure of three reflector that two circular arcs form, and described reflector is connected with support and is fixed in the inner chamber of glass outer tube.
Improve, described reflector layer can be also the bottom surface layer of glass outer tube again, and this bottom surface layer is the reflective inwall that two circular arcs form the figures of three, scribbles reflectorized material and form the reflective surface of the figure of three on the reflective inwall of the figure of three.
As improvement, on the side of described glass outer tube, being provided with can be by the evacuated air exhaust nozzle of the annular chamber of glass outer tube and inner tube.
As improvement, on described metal cover, being provided with can be by the evacuated air exhaust head of the annular chamber of glass outer tube and inner tube.
Improve, be provided with the getter that can absorb gas in annular chamber in described annular chamber, this getter is folded in circular cone sheet.
Compared with prior art, the utility model adopt glass outer tube at least one end by flexure strip energy axial stretching be connected with the interior seal of tube.The advantage of this design is: can effectively overcome between glass outer tube and inner tube, difference due to expansion rate under heating state, at glass outer tube and inner tube, in each self-expansion process, can play cushioning effect, be the flexure strip low length that inner and outer pipes produces because of expansion rate difference that disappeared effectively, thereby thereby avoided difference because of expansion rate to cause sealing-off to lose the sealing property of inner and outer pipes, effectively extend the service life of thermal-collecting tube.
