Technical solution of the present invention: a kind of metal-inner-tube straight-through type vacuum solar heat-gathering pipe, comprise glass outer tube (1), be fitted with the metal inner pipe (2) of a both ends open in the glass outer tube (1), the two-port of metal inner pipe (2) is fixed with end cap (3) respectively, the two ends of outer wall are respectively installed with alloy hoop (4), be respectively arranged with water inlet (6) and delivery port (7) on two end caps (3), the two ends of glass outer tube (1) are separately fixed at an end of alloy hoop (4), the other end of alloy hoop (4) is welded on an end of straight choma (8), the other end of straight choma (8) and metal inner pipe (2) and end cap (3) weld together, and make between glass outer tube (1) and the metal inner pipe (2) and form vacuum interlayer (9).
Described end cap (3) is sleeved on the inwall of metal inner pipe (2) two-port, be set with straight choma (8), corrugated ring (5) and alloy hoop (4) on the outer wall of metal inner pipe (2) one ends successively, one end sintering of glass outer tube (1) is at an end of alloy hoop (4), the other end of alloy hoop (4) is welded on an end of corrugated ring (5), the other end of corrugated ring (5) is welded on an end of straight choma (8), and the other end of straight choma (8) and metal inner pipe (2) and end cap (3) weld together; Be set with straight choma (8) and alloy hoop (4) on the outer wall of metal inner pipe (2) other end successively, the other end sintering of glass outer tube (1) is at an end of alloy hoop (4), the other end of alloy hoop (4) is welded on an end of straight choma (8), and the other end of straight choma (8) and metal inner pipe (2) and end cap (3) weld together.
Described water inlet (6) and delivery port (7) lay respectively on the limit of two end cap (3) and the two is symmetrical.
Described metal inner pipe (2) is the stainless steel plated film tube.Alloy hoop (4) is the iron cobalt nickel alloy ring.Corrugated ring (5) is the wavy metal ring.
Advantage that the present invention has and effect:
1, the present invention is without storage tank, thermal-collecting tube can be directly installed on the pipeline midium or long term and be in the band pressure condition, system can be installed in building and be subjected to can construct simultaneously with building on the best metope of light, realized simply whole at least three season of building centralizedly supply hot water; Solve present solar energy equipment combines last existence with architectural design difficulty, and can reduce system cost greatly, reduced maintenance workload and maintenance cost.
2, existing solar energy heat collection pipe is difficult to the reason successfully promoted the use of in large-scale heating plant, mainly be that traditional system can not pressure-bearing, be the water yield and the temperature that satisfies on-the-spot needs, need a large amount of heat exchangers, efficient is low, the system failure rate height, and equipment and operating cost are all very high, do not reduce user's financial burden though saved the energy.The present invention can directly bear the pressure of water system, therefore can use in the large-scale centralized heating plant fully, and system and device is simple, and operating cost is low, and the reliability height is compared integrated cost with existing solar energy heat collection pipe and reduced greatly.
3, the system that forms of the present invention is installed in building and is subjected to can produce hot water continuously in summer on the best metope of light, can also stop the acute irradiation of the sun to body of wall, effectively reduces indoor temperature, reduces air conditioning energy consumption.
Can be combined into multiple pattern when 4, the system of the present invention's composition installs, realize the coordination of solar energy equipment and facade, not only can not influence the view in city, but also might become the city beautiful scenery.
5, the course of work of the present invention is directly to obtain heat by the heat conduction, and maximum temperature can reach 400 ℃-450 ℃ under the situation of pressure-bearing, can realize the high pressure-temperature closed circulation, can be as the power of heat generating and refrigeration.
6, the present invention can overcome glass outer tube and the metal inner pipe inconsistent problem of expanding with heat and contract with cold fully by the metal bellows that is provided with, in the air-tightness between unlikely destruction glass outer tube and the metal inner pipe behind the metal inner pipe expanded by heating.
7, water inlet of the present invention and delivery port lay respectively on the limit of two end cap and the two is symmetrical, when thermal-collecting tube is horizontally disposed with, the bottom is a water inlet, high-end is delivery port, the air that gathers during water inlet is discharged system smoothly from delivery port, makes that Guan Zhongneng is full of water in the thermal-collecting tube, has overcome that intake-outlet is positioned at the tube hub position in the prior art, the air that thermal-collecting tube gathers when being horizontally disposed with the back water inlet is difficult to discharge system smoothly from delivery port, and making can not water-filled drawback in the pipe in the thermal-collecting tube.
8, the present invention's novelty compared with prior art simple in structure is practical, reliability height, long service life.
