The beneficial effect that the utility model compared with prior art produces is:
This glass metal seal heat pipe solar vacuum heat-collecting pipe is compared with the existing manufacturing technology of metal fever tubular type solar vacuum heat-collecting pipe, be to adopt close sealing glass pipe and the sealing by fusing becket of linear expansion coefficient to mate sealing by fusing, automaticity simpler on structure and technique, equipment increases substantially, production cost reduces, the air-tightness of glass-to-metal seal is better, quality is more reliable, energy consumption is little and precision is easy to control, the internal stress of glass is less, intensity is higher, life of product prolongs.
This glass metal seal heat pipe solar vacuum heat-collecting pipe is reasonable in design, simple in structure, safe and reliable, easy to use, be easy to safeguard, has good value for applications.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model.
Mark in the accompanying drawing represents respectively:
1, heat collecting glass tube, 2, the sealing glass pipe, 3, the sealing by fusing becket, 4, metal heat pipe, 5, the condensation head, 6, the evaporation part, 7, metal heat absorption band, 8, blast pipe.
The specific embodiment
Below in conjunction with accompanying drawing glass metal seal heat pipe solar vacuum heat-collecting pipe of the present utility model is described in detail below.
As shown in drawings, glass metal seal heat pipe solar vacuum heat-collecting pipe of the present utility model, its structure is that heat collecting glass tube 1 front port is provided with sealing glass pipe 2, be socketed with sealing by fusing becket 3 in sealing glass pipe 2 mouths of pipe, sealing glass pipe 2 is connected sealing by fusing and is connected with the sealing by fusing becket, sealing by fusing becket 3 is connected the neck boxing and is connected with metal heat pipe, metal heat pipe 4 front ends are set to condensation head 5, metal heat pipe 4 pipe shafts are set to evaporation part 6, metal heat pipe 4 pipe shafts are arranged in the heat collecting glass tube 1, be provided with metal heat absorption band 7 between metal heat pipe pipe shaft evaporation part 6 and the heat collecting glass tube 1, heat collecting glass tube 1 end is connected with blast pipe 8.Heat collecting glass tube 1 adopts high borosilicate heat collecting glass tube.Heat collecting glass tube 1, metal heat pipe 4, sealing glass pipe 2 and sealing by fusing becket 3 coaxial aligning.
The linear expansion coefficient of sealing glass pipe and sealing by fusing becket is close, sealing glass pipe 2 and sealing by fusing becket 3 coaxial aligning, the internal diameter of sealing glass pipe 2 is slightly larger than the external diameter of sealing by fusing becket 3, the part of sealing by fusing becket 3 is placed in the sealing glass pipe 2, then allow sealing glass pipe 2 melt gradually by heating, 3 oxidations of sealing by fusing becket, allow again glass-metal seal, stopped heating behind the sealing by fusing, the internal stress of sealing glass pipe is removed in Slow cooling and annealing, has just obtained glass-metal sealing by fusing parts together.Obtain after the glass-metal sealing by fusing parts together, sealing by fusing becket 3 is connected with metal heat pipe by boxing connection sealing, sealing glass pipe 2 and larger direct high borosilicate heat collecting glass tube 1 is connect again.Then the tail end of high borosilicate heat collecting glass tube 1 is received circle, vacuumize by blast pipe 8, roasting disappearing evapotranspires getter can to obtain a metal fever tubular type solar vacuum heat-collecting pipe that adopts glass-metal sealing by fusing technology at last.
