Abstract
The utility model relates to a heat pipe vacuum heat collecting pipe with a kovar sealing ring, which is a novel heat collecting pipe of solar heat utilizing equipment. One kovar sealing ring with a bended edge is arranged between a kovar end cover and a flange of a glass pipe. The bended edge of the kovar seal ring is pressed in the flange of the glass pipe, and is in sealing connection with the inner side of the flange of the glass pipe. Welding seal can be directly carried out to the kovar end cover and the kovar sealing ring. The utility model has the advantages that the air tightness of the end cover is good, air leakage or slow air leakage can not be generated, the heat collecting performance of the vacuum heat collecting pipe is improved, and the service life of the heat pipe vacuum heat collecting pipe with a kovar sealing ring is prolonged.
Description
Technical field
The utility model relates to a kind of heat-pipe vacuum heat collecting pipe that can cut down sealing ring that is provided with, it is a kind of novel heat collecting pipe in the solar thermal utilization equipment.
Background technology
At present heat-pipe vacuum heat collecting pipe in the solar thermal utilization equipment and the heat-pipe vacuum heat collecting pipe narrated in patent announcement document CN1028632C and CN107754C, its end cover all are to carry out sealing-in with scolder form in hot-press sealing equipment by cutting down end cap and glass tube flange.Its poor air-tightness is easy to generate gas leakage or chronic leakage phenomenon; The solar collecting performance of this heat-pipe vacuum heat collecting pipe is poor, and service life is short; Especially hot-press sealing apparatus expensive, the process energy consumption is big.
Summary of the invention
The purpose of this utility model provides the good heat-pipe vacuum heat collecting pipe of a kind of end cover air-tightness, can not produce gas leakage or chronic leakage phenomenon.
The purpose of this utility model is achieved in that a kind of heat-pipe vacuum heat collecting pipe that can cut down sealing ring that is provided with, its end cover by can cut down end cap, the glass tube flange constitutes, it is characterized in that: the glass tube flange is provided with the cut down sealing ring of a band crimp, and can cut down the sealing ring crimp is pressed into and is packaged in the glass tube flange, can cut down end cap and can cut down the sealing ring welding, the thickness that can cut down sealing ring is 0.3-1.0mm.
Can cut down sealing ring is drum shape crimp or the barrel-shaped crimp of V.Adopt drum-shaped structure for cutting down sealing ring, when the diameter of vacuum heat collection pipe was 70-100mm, its crimp height was 1-4.5mm;
For adopting the V barrel shaped structure can cut down sealing ring, when the diameter of vacuum heat collection pipe was 100-160mm, its crimp height was 3-8mm.
Because the end cover in this heat-pipe vacuum heat collecting pipe is by cutting down the cut down seal ring seal welding by the band crimp of end cap and glass tube flange, guarantee its air-tightness, can not produce gas leakage or chronic leakage, improve the solar collecting performance of heat-pipe vacuum heat collecting pipe, prolong service life.
Description of drawings
Fig. 1 is that the end cover of heat-pipe vacuum heat collecting pipe cooperates schematic diagram.
Fig. 2 is that drum-shaped structure can cut down the sealing ring schematic diagram.
Fig. 3 is that the V barrel shaped structure can be cut down the sealing ring schematic diagram.
Among the figure, 1, can cut down end cap, 2, can cut down sealing ring, 3, can cut down the sealing ring crimp, 4, the glass tube flange.
Specific embodiment
A kind of heat-pipe vacuum heat collecting pipe that can cut down sealing ring that is provided with, its end cover is formed with glass tube flange 4 by cutting down end cap 1.Glass tube flange 4 is provided with the cut down sealing ring 2 of a band crimp, when forming by a firing glass tube flange 4, can cut down sealing ring crimp 3 and directly be pressed into sealing-in in glass tube flange 4, can cut down end cap 1 Gai Zaike and cut down on the sealing ring 2, the two be welded with Laser Welding or argon arc welding.
Can cut down sealing ring 2 designs has two kinds of structures, and a kind of is drum shape crimp structure, and another kind is the barrel-shaped crimp structure of V.For adopting drum-shaped structure, when the diameter of vacuum heat collection pipe was 70-100mm, its height that can cut down sealing ring crimp 3 was 1-4.5mm; For adopting the V barrel shaped structure, when the diameter of vacuum heat collection pipe was 100-160mm, its height that can cut down sealing ring crimp 3 was 3-8mm.
Because the end cover in this heat-pipe vacuum heat collecting pipe is the cut down sealing ring 2 that is provided with a band crimp between end cap 1 and the glass tube flange 4 cutting down, be pressed into sealing-in behind glass tube flange 4 can cutting down sealing ring crimp 3, end cap 1 can be cut down and sealing ring 2 usefulness Laser Welding can be cut down or argon arc welding is welded, thereby improved the air-tightness of its end cover, can not produce gas leakage or chronic leakage, improve the solar collecting performance of heat-pipe vacuum heat collecting pipe, prolonged service life; And need not use hot-press sealing equipment in the process, reduce cost and energy consumption.
Claims (5)
1, a kind of heat-pipe vacuum heat collecting pipe that can cut down sealing ring that is provided with, its end cover by can cut down end cap, the glass tube flange constitutes, it is characterized in that: the glass tube flange is provided with the cut down sealing ring of a band crimp, and can cut down the sealing ring crimp and be pressed into and be packaged in the glass tube flange, can cut down end cap and can cut down the seal ring seal welding.
