Abstract
The utility model discloses a solar evacuated collector tube, which comprises an outer glass tube and an inner glass tube, wherein the inner glass tube is positioned in the outer glass tube; and an evacuated chamber is formed between the outer glass tube and the inner glass tube. The solar evacuated collector tube is characterized in that the inner glass tube is arranged in the outer glass tube to form an eccentric structure, namely the geometric center of the inner glass tube is deflected from that of the outer glass tube; and one side of the outer glass tube is close to the inner glass tube, and a mercury coating is coated on the side. The solar evacuated collector tube forms the eccentric structure, so that an optimal heat concentration effect is achieved.
Description
Technical field
The utility model relates to a kind of solar vacuum heat-collecting pipe, belongs to solar energy application element thereof field.
Background technology
As a kind of new energy, solar energy has obtained increasing application in daily life and commercial Application, and its development and use also more and more come into one's own.The trans-utilization efficient of solar energy is to utilize closely-related with solar energy; In helioplant; Solar vacuum heat-collecting pipe is an important part, and the pipe reflector efficiency is relatively poor in traditional solar energy heat collection pipe, and heat build-up efficient is low; Cause thermal medium in the thermal-collecting tube need pass through the heating of long period and could obtain higher temperature, greatly reduce the effect of solar energy.Simultaneously pipe all is to fix through fixing supporting framework with outward appearance in the existing heating in vacuum pipe owing to lack necessary buffer capacity, when running into vibrations or rocking in pipe damage appears easily.
Summary of the invention
To the defective of existing solar vacuum heat-collecting pipe, the utility model discloses a kind of novel solar vacuum heat-collecting pipe, through improving its internal structure position, Heat-collecting effect is increased greatly, thereby improved solar energy utilization rate.
For realizing above-mentioned purpose, the utility model is to adopt following technical proposals to realize:
A kind of solar vacuum heat-collecting pipe; Comprise outer glass pipe and inner glass tube; Said inner glass tube is positioned at outer glass pipe; Be vacuum chamber between said outer glass pipe and the inner glass tube, wherein said inner glass tube is built in the outer glass pipe with eccentric structure, i.e. the geometric center offset of the geometric center of inner glass tube and outer glass pipe; Wherein, said outer glass pipe covers the mercury coating near inner glass tube one side.
Through adopting said structure, thermal-collecting tube is under irradiation of sunlight, and sunlight is penetrated at outer glass pipe and reflexed to inner glass tube, plays the heat build-up effect.Because the mercury coating is plated in having near the inner glass tube eccentric part of outer glass pipe; Make the sunlight reflected effect better; Part sunlight reflected to the interior pipe of plating mercury coating; The in the shade face of inner glass tube that feasible script can't absorb sunshine also can absorb and the conversion solar ability effectively, has improved the overall solar absorption amount of inner glass tube, makes the heat build-up best results.
Wherein, said inner glass tube, outer glass pipe are pipe, are provided with spring support below the said inner glass tube and support.Through adopting the spring support structure; The support that forms between inner glass tube and the outer glass pipe not only can be played the fixedly effect of inner glass tube; Simultaneously can constitute certain cushioning effect to inner glass tube again, prevent owing to unexpected vibrations, landing etc. cause thermal-collecting tube to damage.
Further, said outer glass pipe end is provided with protective cap.
Through the said structure design, can utilize inner glass tube, outer glass pipe can absorb the part of solar energy to greatest extent, improve solar energy utilization rate, produce higher optically focused ratio, it is best that heat build-up was imitated; Improve through internal structure simultaneously, improved the steadiness of inner glass tube, improved whole service life.
Description of drawings
Fig. 1 is the solar vacuum heat-collecting pipe structural representation;
Fig. 2 is the profile of solar energy evacuated heating tube.
The specific embodiment
Can better understand the utility model in conjunction with accompanying drawing, said accompanying drawing only is used to explain a kind of more excellent enforcement of the utility model, for example changes the eccentric degree of inner glass tube etc., still belongs to the protection domain of the utility model.
With reference to figure 1; The solar vacuum heat-collecting pipe of the utility model comprises outer glass pipe 1, and outer glass pipe 1 end is provided with protective cap 5; Inside is provided with inner glass tube 2; Be vacuum chamber 3 between outer glass pipe 1 and the inner glass tube 2, wherein inner glass tube 2 is built in the outer glass pipe 1 with eccentric structure, through spring support structure 4 fixed support inner glass tubes 2; Outer glass pipe 1 covers mercury coating 6 near inner glass tube 2 one sides.
With reference to figure 2, shown the cross-section structure of solar vacuum heat-collecting pipe.
Claims (3)
1. solar vacuum heat-collecting pipe; Comprise outer glass pipe and inner glass tube; Said inner glass tube is positioned at outer glass pipe; Be vacuum chamber between said outer glass pipe and the inner glass tube, it is characterized in that said inner glass tube is built in the outer glass pipe with eccentric structure, i.e. the geometric center offset of the geometric center of inner glass tube and outer glass pipe; Said outer glass pipe covers the mercury coating near inner glass tube one side.
2. solar vacuum heat-collecting pipe according to claim 1 is characterized in that said inner glass tube, outer glass pipe are pipe, is provided with spring support below the said inner glass tube and supports.
