Abstract
The utility model provides a metal/glass shelled vacuum collector tube on a solar water heater, consisting of a glass shell (7), a metal inner container (8), a pair of end enclosures (2), a water outlet tube (1) and a water inlet tube (10). The metal inner container (8) with a layer of heat-absorbing coating is used as a water container and is arranged coaxially in the glass shell (7). An empty cavity (6) is formed between the exterior surface of the cylindrical face of a metal cylinder and the interior wall of the glass shell (7). An air tap (3) is arranged at one terminal of the vacuum collector tube. Thermal insulation material (4) is filled between the end enclosures (2) and the exterior end cover (5). The empty cavity (6) is filled with inert gas or is vacuumized. The difference between the diameter of the glass shell (7) and that of the metal inner container (8) is 10 to 15mm. The diameter of the glass shell (7) is 70 to 220mm while that of the metal inner container (8) is 60 to 205mm. And the length of the vacuum collector tube is 800 to 2300mm. The utility vacuum collector tube has the advantages of simple and reasonable structure, good effect of solar absorption, multiple choices of material and diversified and easy manufacturing process, thereby, is fit for mass production.
Description
Technical field
The utility model relates to a kind of solar water heater metal-glass bulb vacuum heat collection pipe, belongs to the vacuum heat collecting device in the field of solar energy utilization, particularly metal inner tube formula solar vacuum heat-collecting pipe.
Background technology
Adopting vacuum technique to collect solar energy grew up in recent years, in the vacuum tube type of glass-metal combination, heat pipe type solar vacuum pipe and metal fin formula solar energy vacuum tube are arranged, and these solar vacuum heat-collecting pipes have advantages such as being difficult for broken and easy installation in the elevated pressures of bearing, freeze proof, the empty solarization.But, the solar water heating system structure that these solar vacuum heat-collecting pipes constitute is complicated, and the surperficial wall temperature that absorbs heat is higher, under stagnation (promptly not having thermal output) state above 200 ℃, descend absorber plate also often above 100 ℃ in working order, therefore, no matter from design and processes, or on the benefit of the thermal efficiency and investment not optimal selection.
Summary of the invention
That the purpose of this utility model provides is rational in infrastructure, efficient heat-collecting, modified metal inner tube formula solar vacuum heat-collecting pipe that heat insulating effect is good.
The purpose of this utility model is to realize by following technical scheme: solar water heater metal-glass bulb vacuum heat collection pipe is mainly by glass shell 7, metal inner tube 8, a pair of end socket 2, outlet pipe 1 and water inlet pipe 10 are formed, outer surface scribbles the metal inner tube 2 of heat absorbing coating as a water container, the coaxial glass tube 7 that places, form cavity 6 between the inwall of the outer surface of metal cylinder cylinder and glass tube 7, the termination of vacuum heat collection pipe is provided with valve 3, is full of insulation material 4 between end socket 2 and the outer end cap 5.
Described vacuum heat collection pipe vacuumizes by being full of in inert gas or the cavity 6 in the cavity 6.
Described vacuum heat collection pipe, glass shell 7 is 10-15mm with the diameter difference of metal inner tube 8.
Described vacuum heat collection pipe, the diameter of glass shell 7 is 70-220mm, the diameter of metal inner tube 8 is 60-205mm.
Described vacuum heat collection pipe, the length of vacuum heat collection pipe is 800-2300mm.
The utility model vacuum heat collection pipe compared with prior art has simple and reasonable for structurely, and Heat-collecting effect is good, and the selection of material, implementing process be more versatile and flexibleization all, and easier manufacturing is convenient to produce in enormous quantities the advantages such as product of super quality and competitive price.
Description of drawings
Fig. 1 is the structural representation of the utility model solar-energy water heater vacuum thermal-collecting tube;
The specific embodiment
Below with reference to accompanying drawing the utility model is further described;
With reference to Fig. 1, this kind metal inner tube formula solar vacuum heat-collecting pipe, it mainly is by glass tube 7, metal cylinder inner bag 8, outer surface scribbles heat absorbing coating 9, metal inner tube 2 is as a water container, and the coaxial glass tube 7 that places forms cavity 6 between the inwall of the outer surface of metal cylinder cylinder and glass tube 7, the termination of vacuum heat collection pipe is provided with valve 3, is full of insulation material 4 between end socket 2 and the outer end cap 5.
Vacuumize by being full of in inert gas or the cavity 6 in the cavity 6.Glass shell 7 is 10-15mm with the diameter difference of metal inner tube 8.The diameter of glass shell 7 is 70-220mm, and the diameter of metal inner tube 8 is 60-205mm.The length of vacuum heat collection pipe is 800-2300mm.Outlet pipe 1 and water inlet pipe 10 are respectively at the two ends of vacuum heat collection pipe.
Glass tube of the present utility model should be selected for use with existing extraordinary soda-lime glass of finalizing the design expansion and heterogeneous coupling and be drawn into pipe.Aspect process for sealing, the utility model has been selected low-melting glass scolder process for sealing, and glass tube and loam cake are carried out the scolder sealing-in, and the sealing-in reliability is improved, and long-term vacuum life is guaranteed.Because the interlayer between the can that metal inner tube and glass are formed is pumped into high vacuum state, glass tube has high transmitance, the metal inner tube outer surface can obtain absorptivity height and the low selectivity rete of emissivity, and metal inner tube can bear tap water supply pressure, therefore, the utility model solar vacuum heat-collecting pipe has advantages such as efficient heat-collecting, excellent insulating effect of heat insulation and pressure-bearing use.
Form a cavity interlayer 6 between the outer surface of metal cylinder cylinder and the inwall of glass tube, make the cavity interlayer form the space of a sealing after loam cake and the glass tube welding, and the outer surface of metal barrel mast is a coating for selective absorption face 9, outlet pipe is drawn from metal cylinder upper end central part, also can on metal cylinder, draw by end periphery, water inlet pipe places and leads to the metal cylinder bottom in the outlet pipe, and loam cake can be made by glass material or metal material.Blast pipe is made by metal material, and it is welded in loam cake from the metal inboard, and draws from outlet pipe.
