The grooves (9) are formed in the outer wall and the inner wall of the glass inner pipe (2), so that the absorption area of the surface is enlarged; the heat performance is improved; and the anti-pressure capacity of the heat collection pipe is improved.
Description
Technical field
The utility model relates to a kind of full glass solar heat collection pipe, particularly a kind of solar vacuum heat-collecting pipe that improves absorption area and improve anti-pressure ability.
Background technology
Solar vacuum heat-collecting pipe is the core component in solar heating engineering, solar heat power generation system.At present, full-glass solar energy collecting vacuum tube is divided into single-ended opening and dual-end (leading directly to) two classes.
The patent No. 87210032 is a kind ofly by interior outer glass pipe sealing-in, to be vacuumized and the single-ended opening full-glass solar energy collecting vacuum tube that forms, interior outer tube layer has solar selectively absorbing coating, an other end of inner tube is as free end, its effect is used for regulating inner tube because of the cold and hot length variations caused, this thermal-collecting tube can not bear higher pressure.
The patent No. 99107429 is a kind of dual-end spiral straight-flow type whole-glass solar vacuum heat-collecting pipes, the glass inner tube skin of this thermal-collecting tube has solar selectively absorbing coating, its two ends vacuumize composition with the two ends sealing-in of glass outer tube respectively, wherein an end of inner tube is the glass helix tube, its objective is and attempt to regulate with it the length variations that inner tube causes because of its thermal expansion, reduce or eliminate stress, the absorption area of this thermal-collecting tube is limited.
The utility model content
The purpose of this utility model is to overcome the shortcoming of prior art, and a kind of solar vacuum heat-collecting pipe that improves absorption area and improve anti-pressure ability is provided.
The purpose of this utility model is achieved through the following technical solutions: a kind of solar vacuum heat-collecting pipe that improves absorption area and improve anti-pressure ability, it comprises glass inner tube, glass outer tube and bracing frame, glass inner tube is arranged in the glass outer tube, the inner and outer wall of glass inner tube is equipped with groove, the outer surface of glass inner tube is provided with solar selectively absorbing coating, glass inner tube one end is evaporator section, an other end is condensation segment, be tightly connected and form vacuum layer by the transition attaching parts between glass outer tube and glass inner tube, be placed with getter in vacuum layer, be provided with bracing frame between glass outer tube and glass inner tube.Be provided with heat transfer medium in described evaporator section.
The utlity model has following advantage:
One, that the vacuum tube surface is had is concavo-convex for the groove on glass inner tube outer wall of the present utility model, increases the absorption area on vacuum tube surface, has improved hot property.
Two, the groove on glass inner tube inwall of the present utility model, be equivalent to on vacuum tube together " reinforcement ", thereby increased the anti-pressure ability of vacuum pipe heat-collecting pipe.
Three, the utlity model has better sealing, and it is poor better to eliminate swell increment.
The accompanying drawing explanation
