Abstract
The invention discloses a solar heat-collecting corrugated pipe. The solar heat-collecting corrugated pipe comprises an outer glass pipe, an inner metal corrugated pipe and low-expansion coefficient alloys, wherein the inner metal corrugated pipe is arranged on the inner side of the outer glass pipe and is combined with the outer glass pipe; a vacuum layer is arranged between the inner metal corrugated pipe and the outer glass pipe; one or more waves are formed on the inner metal corrugated pipe; the low-expansion coefficient alloys are arranged at the two ends of the inner metal corrugated pipe and are used for connecting the inner metal corrugated pipe and the outer glass pipe in a sealing way, so that the inner metal corrugated pipe and the outer glass pipe are connected into a whole in the sealing way.
Description
Technical field
The present invention relates to the special high-temperature heat-gathering corrugated stainless steel tubing of a kind of solar energy heating bellows, particularly a kind of solar energy, be mainly suitable for high-temperature heat-collection pipe application more than 250 degree.
Background technology
Stainless steel metal thermal-collecting tube has the fast feature of heat-transfer rate, its heat-transfer rate is 10-13 times of simple glass thermal-collecting tube, can Fast Heating heat-conducting medium, be widely used in solar air conditioner, solar energy thermo-power station, solar boiler, wall-hanging solar, large-scale heat collecting engineering etc.But due to large (approximately 17.3) of coefficient of thermal expansion and contraction of collector metal pipe, and the coefficient of thermal expansion and contraction of glass tube is very little by (approximately 3.3, and glass heat collection tube is not suitable for middle high temperature utilization), therefore in use metal tube is easy to cause glass tube bombing, and this has just restricted the application of solar energy on middle high-temperature heat-gathering.
Summary of the invention
The object of the invention is to overcome the deficiency of above-mentioned thermal-collecting tube, provide a kind of solar energy special high-temperature heat-gathering corrugated stainless steel tubing.
A kind of solar energy heating bellows, comprising: outer glass pipe, interior metal bellows, Lo-Ex; Interior metal bellows is arranged on outer glass pipe inner side, and be combined with outer glass pipe, between interior metal bellows and outer glass pipe, form vacuum layer, ripple on interior metal bellows is one or more, Lo-Ex is located at interior metal bellows two ends, for interior metal bellows and outer glass pipe sealing-in, interior metal bellows and outer glass pipe sealing-in are integrated.
Further, the coefficient of expansion of Lo-Ex and glassy phase are same, are about 3.3.
Further, interior metal bellows is stainless steel material, and stainless steel is 304 stainless steel materials.
Further, be suitable for working under 250-500 ℃ of high temperature.
Adopt the thermal-collecting tube of said structure can utilize dexterously the elastic reaction of metal bellows, effectively absorbed the effect of expanding with heat and contract with cold that metal solar pipe produces in the time that high temperature is applied.Avoid outer glass pipe bombing.Used the low-expansion coefficient the same with glass swelling coefficient to close at stainless steel metal bellows two ends seals simultaneously, wavy metal heat pipe is sealed with outer glass pipe easily, and formation is suitable for the metallic high temperature thermal-collecting tube using under 250-500 ℃ of high temperature.
Accompanying drawing explanation
Fig. 1 is the structural representation of solar energy heating bellows.
the specific embodiment
Referring to accompanying drawing, solar energy heating bellows of the present invention, comprising: outer glass pipe 1, interior metal bellows 5, Lo-Ex 4; Interior metal bellows 5 is arranged on outer glass pipe 1 inner side, and with outer glass pipe 1 combination, between interior metal bellows 5 and outer glass pipe 1, form vacuum layer 3, ripple 2 on interior metal bellows 5 is one or more, Lo-Ex 4 is located at interior metal bellows 5 two ends, for interior metal bellows 5 and outer glass pipe 1 sealing-in, interior metal bellows 5 is integrated with outer glass pipe 1 sealing-in.
And, to adopt the coefficient of expansion be 3.3 Lo-Ex, its coefficient of expansion and glassy phase together, can be easily with together with the high-boron-silicon glass pipe sealing by fusing of the coefficient of expansion 33 and do not produce stress effect.Interior metal bellows is 304 stainless steel materials.
The advantage of solar energy heating bellows is to integrate bellows and straight pipe, adopts the moulding of bellows process equipment one-off drawing, due to simple in structure, has greatly improved the automated production degree of product, has reduced significantly material and production cost; Reduce many places tie point in the past and, because of the vacuum leak problem that welding causes, guaranteed vacuum when heat-collecting pipe vacuum chamber is used for a long time.
