Abstract
The utility model provides a multistage heating solar water heater, including evacuated collector tube and heat storage water tank, evacuated collector tube includes inner glass tube, inner glass tube sets up cover glass pipe outward, set up the vacuum intermediate layer between inner glass tube and the cover glass pipe, the inner glass tube surface is provided with sun selective absorption coating, evacuated collector tube stretches into, and its inner glass tube of one end of heat storage water tank covers glass pipe range 120mm~160mm, the some formation of sending forth conduction heat transfer wall, make the solar water heater pipe increase the conduction heat transfer on original heat convection's basis, solar water heater's heat transfer speed has been accelerated.
Description
Technical field
This utility model relates to a kind of solar water heater, more particularly to a kind of Multi-stage heating
Solar water heater.
Background technology
At present, heat-collecting part in the market has common all-glass vacuum tube, glass metal structure
Vacuum tube, heat pipe type vacuum pipe, all-glass vacuum thermal-collecting tube solar water heater is due to its thermal starting relatively
Slowly, cause its thermal efficiency relatively low；And glass metal structure for vacuum pipe and heat pipe type vacuum pipe need
Metal tube (typically using copper tube) is the highest as its manufacturing cost of heat carrier, metal current and glass
Sealing by fusing the most thoroughly solve, its life-span need to verify further.
Summary of the invention
In order to overcome the deficiencies in the prior art, this utility model provides a kind of Multi-stage heating too
Sun can water heater.
This utility model is achieved through the following technical solutions: a kind of Multi-stage heating solar water
Device, including vacuum heat collection pipe and heat storage water tank, described vacuum heat collection pipe includes inner glass tube, interior glass
Pipe is outer arranges cover glass tube, arranges vacuum interlayer, outside inner glass tube between inner glass tube and cover glass tube
Surface configuration has sun Selective absorber coating, and vacuum heat collection pipe puts in one end of heat storage water tank glass in it
Manage relatively cover glass tube long, grow part and form conduction heat exchange wall.
In such scheme, described inner glass tube relatively cover glass tube elongation 120mm～160mm.
This utility model one Multi-stage heating solar water heater compared with prior art, its beneficial effect
It is:
1, the part that inner glass tube stretches out compared with cover glass tube is as conduction heat exchange wall, makes solar water
Device pipe adds conduction heat exchange on the basis of original heat convection, accelerates changing of solar water heater
Thermal velocity.
2, heat-collecting part puts in the part of attemperater and has lengthened, and reduces and deposits to heat-collecting part
The possibility of incrustation scale.
Accompanying drawing explanation
Accompanying drawing is the structural representation of this utility model a kind of Multi-stage heating solar water heater.
In figure: 1. heat storage water tank, 2. water, 3. the inner tube mouth of pipe, 4. conduction heat exchange wall, 5. cover glass tube,
6. sun Selective absorber coating, 7. vacuum interlayer, 8. inner glass tube, 9. vacuum heat collection pipe.
Detailed description of the invention
With specific embodiment, this utility model Multi-stage heating solar water heater is made below in conjunction with the accompanying drawings
Further description:
Accompanying drawing is the structural representation of this utility model a kind of Multi-stage heating solar water heater.In figure,
This Multi-stage heating solar water heater, including vacuum heat collection pipe 9 and heat storage water tank 1, described vacuum collection
Heat pipe 9 includes inner glass tube 8, arranges cover glass tube 5, inner glass tube 8 and cover outside inner glass tube 8
Vacuum interlayer 7 is set between glass tubing 5, is used for the hot water in inner glass tube 8 is incubated, interior
Glass tubing 8 outer surface is provided with sun Selective absorber coating 6, is used for absorbing the heat of the sun, vacuum
Thermal-collecting tube 9 puts in one end inner glass tube 8 relatively cover glass tube 5 of heat storage water tank 1 and extends one section, shape
Become conduction heat exchange wall 4, a length of 120mm～160mm of conduction heat exchange wall 4.
During work, the water 2 in heat storage water tank 1 is by the inner tube mouth of pipe 3 and the hot water in inner glass tube 8
Carrying out heat convection, meanwhile, the water 2 in heat storage water tank 1 is further through conduction heat exchange wall 4 and interior glass
Hot water in pipe 8 carries out conducting heat exchange, makes solar water heater pipe on the basis of original heat convection
Add conduction heat exchange, and the speed conducting heat exchange is far above heat convection naturally, thus accelerate
The heat transfer rate of solar water heater, improves the collecting efficiency of solar water heater.
The above, be only preferred embodiment of the present utility model, not makees this utility model
Any pro forma restriction, although this utility model is disclosed above with preferred embodiment, but not
In order to limit this utility model, any those skilled in the art, without departing from this utility model
In the range of technical scheme, when the method for available the disclosure above and technology contents make a little change or
It is modified to the Equivalent embodiments of equivalent variations, as long as without departing from technical solutions of the utility model
Appearance, any simple modification above example made according to technical spirit of the present utility model, equivalent
Change and modification, still fall within the range of technical solutions of the utility model.
