Balcony separated type solar water heater
Technical field
The present invention relates to a kind of solar water heater.
Background technology
Though it is indoor that the separated type solar water heater that storage tank separates with vacuum heat collection pipe can be placed on water butt, the advantage that visual appearance is arranged, but the nature of the circulation of the water in the water heater is destroyed, need keep inner water circulation with external force, as water pump is installed.Under the situation of using water pump, intrasystem each parts all are pressure-bearings, bring structure, installation requirement to each parts to improve thus, and system architecture is complicated, and cost rises.Simultaneously, water pump need consume electric power, needs to connect power supply, and itself damages easily, and potential safety hazard is arranged.
In addition, the non-top layer resident family of high building is difficult to use the water heater of common form, and the place that sunlight is arranged that resident family is unique is a balcony, but common solar water heater can't be installed on balcony.
Summary of the invention
The present invention will solve the above-mentioned shortcoming of existing separated type solar water heater, a kind of simple in structure, stable and reliable operation is provided, need not energy input, is adapted at the solar water heater that balcony is installed.
Balcony separated type solar water heater of the present invention is characterized in that:
Comprise a header that is used to install one group of vacuum glass heat collection tube;
One is fit to described header so that receive the angle setting support on balcony of sunlight;
Described thermal-collecting tube is horizontal, and is immersed in the interior water of described header;
The top of described header connects an outlet pipe, and the bottom of described header connects a return duct, and the other end connection one of described outlet pipe places the top of indoor heat-exchanging water tank, and the other end of described return duct connects the bottom of described heat-exchanging water tank;
The space on the water surface top of described heat-exchanging water tank is communicated with atmosphere;
Be provided with heat exchanger in the described heat-exchanging water tank, the water inlet of described heat exchanger is connected water-supply-pipe and tap respectively with delivery port.
Further, described vacuum glass heat collection tube is the three-chamber solar energy vacuum tube, comprises somely being made up of and with evacuated thermal-collecting tube between the inside and outside glass tube, described inner glass tube surface is coated with absorption film outer glass pipe, inner glass tube; Be provided with interior bile duct in the described thermal-collecting tube, the upper end of described interior bile duct is fixed in the described thermal-collecting tube by the elasticity button.
Further, described elasticity button is made up of the flexure strip that the end links together, and described flexure strip is in the link bending, and elasticity button integral body presents bowl-shape.
Header of the present invention, thermal-collecting tube, heat-exchanging water tank have been formed the heating agent system, this system is the Natural Circulation of non-pressure-bearing, utilize the natural circulation characteristic of hot and cold water to keep the intrasystem water circulation of heating agent, need not the extra power input, simple for structure, reliable, long service life.
The storage tank built-in heat exchanger, the super large heat exchange area can make transient heating water, and it is consistent with parent water that leaving water temperature reaches, the pressure-bearing water outlet, water is comfortable.
The present invention has also solved the difficult problem that solar water heater is installed on the balcony of the resident family of skyscraper, header separates with heat-exchanging water tank, heat-exchanging water tank is arranged on indoor, and header is erect on balcony, and thermal-collecting tube is horizontal can avoid the problem of the balcony insufficient height that the common perpendicular mode of putting brings.Thermal-collecting tube after simultaneously horizontal is met to sunlight with periphery, and it is little with the angle relevance of the relative sunlight of header that it adopts thermal effect, is convenient to place header according to the space of balcony.
Advantage of the present invention is: be convenient to install and use at high-rise balcony, simple in structure, stable and reliable operation, need not energy input, with low cost.

The specific embodiment
With reference to accompanying drawing, further specify the utility model:
Balcony separated type solar water heater of the present invention comprises a header 1 that is used to install one group of vacuum glass heat collection tube;
One is fit to described header 1 so that receive the angle setting support 2 on balcony of sunlight;
Described thermal-collecting tube 3 is horizontal, and is immersed in the water in the described header 1;
The top of described header 1 connects an outlet pipe 4, the bottom of described header 1 connects a return duct 5, the other end connection one of described outlet pipe 4 places the top of indoor heat-exchanging water tank 6, and the other end of described return duct 5 connects the bottom of described heat-exchanging water tank 6;
The space on the water surface top of described heat-exchanging water tank 6 is communicated with atmosphere;
Be provided with heat exchanger 7 in the described heat-exchanging water tank 6, the water inlet 71 of described heat exchanger is connected water-supply-pipe and tap respectively with delivery port 72.
Described thermal-collecting tube 3 is three-chamber solar energy vacuum tubes, comprises somely being made up of and with evacuated thermal-collecting tube 3 between the inside and outside glass tube 32,31, described inner glass tube 32 surfaces are coated with absorption film outer glass pipe 31, inner glass tube 32; Bile duct 33 in being provided with in the described thermal-collecting tube 3, the upper end of described interior bile duct 33 is fixed in the described thermal-collecting tube 3 by elasticity button 34.
Described elasticity button 34 is made up of the flexure strip 341 that the end links together, and described flexure strip 341 is in the link bending, and elasticity button integral body presents bowl-shape.
Header 1 of the present invention, thermal-collecting tube 3, heat-exchanging water tank 6 have been formed the heating agent system, this system is the Natural Circulation of non-pressure-bearing, utilize the natural circulation characteristic of hot and cold water to keep the intrasystem water circulation of heating agent, need not the extra power input, simple for structure, reliable, long service life.
Heat-exchanging water tank built-in heat exchanger 7, the super large heat exchange area can make transient heating water, and it is consistent with parent water that leaving water temperature reaches, the pressure-bearing water outlet, water is comfortable.
The present invention has also solved the difficult problem that solar water heater is installed on the balcony of the resident family of skyscraper, header 1 separates with heat-exchanging water tank 6, heat-exchanging water tank 6 is arranged on indoor, and header 9 is erect on balcony, and thermal-collecting tube 3 is horizontal can avoid the problem of the balcony insufficient height that the common perpendicular mode of putting brings.Thermal-collecting tube 3 after simultaneously horizontal is met to sunlight with periphery, and it is little with the angle relevance of header 1 relative sunlight that it adopts thermal effect, is convenient to place header according to the space of balcony.
This formal system is applicable to balcony and facade installation, be particularly suitable for little high level and high-rise installation, can solve conventional solar water heater in little high level and the high-rise a series of problems (, problems such as hydraulic pressure too small) that run into of installing as area, system adopts the pressure-bearing type vacuum tube, and annual collecting efficiency is stable.In current solar energy and architecture-integral process, broken through the bottleneck that balcony is installed.
The described content of this specification embodiment only is enumerating the way of realization of inventive concept; protection scope of the present invention should not be regarded as only limiting to the concrete form that embodiment states, protection scope of the present invention also reach in those skilled in the art conceive according to the present invention the equivalent technologies means that can expect.
