Description
Technical field
The utility model relates to a kind of vacuum tube that is used on the solar water heater.
Background technology
To be the energy that utilizes the sun be heated to the device of high-temperature with water from low temperature to the solar water heater, is a kind of heat energy product.The solar water heater is made up of all-glass vacuum thermal-collecting tube, storage tank, support and related accessories, converts solar energy to heat energy and mainly relies on glass heat-collecting vacuum tube.Thermal-collecting tube receives the solar radiation surface temperature high, and thermal-collecting tube opaco temperature is low, and water just produces temperature difference reaction in the pipe, and the principle of utilizing hot water come-up cold water to sink makes the water generates microcirculation and reaches required hot water.
Solar water heater is the big industry of one in the solar energy application of result; It provides the New-type water heater product of environmental protection, energy-saving safe, health for the common people; Solar water heater is exactly the radiant heat energy that absorbs the sun, and heating cold water offers the energy-saving equipment that people use in life, production.
In solar water heater, vacuum tube is an important components, and the quality of solar water heater has directly relevantly closely with vacuum tube, and for this reason, a lot of producers all spend great energy research vacuum tube, to improve whole heat absorption usefulness.
But, existing solar water heater, vacuum tube exists efficiency of utilization low, and high temperature resistance and low temperature resistivity can be poor, cause the solar water heater serviceability to reduce greatly, and service life is short, the client is caused use inconvenience, is unfavorable for long-run development.
By on can know that addressing these problems is extremely urgent!
In view of this, the inventor has done deep research, and by feat of the experience of being engaged in relevant industries for many years and practice; Design a kind of vacuum tube that is used on the solar water heater, can solve deficiency of the prior art, exquisiteness simple in structure; Efficiency of utilization is high; Life-span is permanent, high temperature resistant anti-low temperature, and this case produces thus.
Summary of the invention
The purpose of the utility model is to provide a kind of vacuum tube that is used on the solar water heater, can solve deficiency of the prior art, exquisiteness simple in structure, and efficiency of utilization is high, and the life-span is permanent, high temperature resistant anti-low temperature.
To achieve these goals, the technical scheme of the utility model is following:
Be used for the vacuum tube on the solar water heater; Pipe and outer tube in comprising; The cross section of pipe is circular in said, and it is characterized in that: the cross section of said outer tube is a polygon, between outer tube and interior pipe, forms vacuum chamber; The tube wall of pipe is provided with heat-sink shell in said, and said heat-sink shell is processed by the stainless steel aluminium nitride;
The beneficial effect of the utility model: the cross section of the outer tube in the utility model is a polygon, and such structure can improve the sunlight ray refraction, obtains bigger solar thermal energy, improves the utilization of the thermal efficiency and obtains;
Between outer tube and interior pipe, form vacuum chamber, the tube wall of said interior pipe is provided with heat-sink shell, and said heat-sink shell is processed by the stainless steel aluminium nitride, such setting, and the Stability Analysis of Structures performance is good, is not easy to wear out, and increases substantially high temperature resistant low temperature resistivity ability.
By on can know, the utility model exquisiteness simple in structure, efficiency of utilization is high, the life-span is permanent, high temperature resistant anti-low temperature.
In order further to explain the technical scheme of the utility model, come the utility model is set forth in detail through specific embodiment below.

Label declaration
Interior pipe 1 outer tube 2
The specific embodiment
As shown in Figure 1; The utility model relates to a kind of vacuum tube that is used on the solar water heater, and pipe 1 and outer tube 2 in comprising, the cross section of said interior pipe are circular; It is characterized in that: the cross section of said outer tube 2 is a polygon; Between outer tube 2 and interior pipe 1, form vacuum chamber 3, the tube wall of said interior pipe 1 is provided with heat-sink shell 4, and said heat-sink shell 4 is processed by the stainless steel aluminium nitride;
Above-mentioned setting, the cross section of the outer tube 2 in the utility model is a polygon, such structure can improve the sunlight ray refraction, obtains bigger solar thermal energy, improves the utilization of the thermal efficiency and obtains;
Between outer tube 2 and interior pipe 1, form vacuum chamber 3, the tube wall of said interior pipe 1 is provided with heat-sink shell 4, and said heat-sink shell 4 is processed by the stainless steel aluminium nitride, such setting, and the Stability Analysis of Structures performance is good, is not easy to wear out, and increases substantially high temperature resistant low temperature resistivity ability.
By on can know, the utility model exquisiteness simple in structure, efficiency of utilization is high, the life-span is permanent, high temperature resistant anti-low temperature.
The embodiment that the above is merely the utility model is not the restriction to this case design, and all equivalent variations of doing according to the design key of this case all fall into the protection domain of this case.
