Abstract
The utility model provides a heat collection pipe and belongs to the technical field of solar energy. The heat collection pipe solves the technical problem that the vacuum degree detected inside an existing solar heat collection pipe is not good. The heat collection pipe comprises an inner pipe body and an outer pipe body located outside the inner pipe body. The heat collection pipe is characterized in that a clamp is arranged between the inner pipe body and the outer pipe body, the outer pipe body and the inner pipe body are fixedly connected into a whole in a sealed mode, the space between the outer pipe body and the inner pipe body is in the vacuum state, a water inlet is formed in one end of the inner pipe body, the other end of the inner pipe body is sealed, the outer pipe wall of the inner pipe body is coated with a heat collection layer, and the inner wall of the outer pipe body is coated with a barium layer. According to the heat collection pipe, the vacuum degree between the inner pipe body and the outer pipe body can be observed by naked eyes.
Description
Technical field
The utility model belongs to technical field of solar, relates to a kind of thermal-collecting tube.
Background technology
Along with economic develop rapidly, the sharp increase day by day of energy-output ratio, on the earth that we are lived, the energy is more and more deficienter.And solar energy is the inexhaustible energy to us, therefore, for the utilization of solar energy, entered into widely people productive life.Wherein, solar water heater is exactly that one of them is applied very widely.Solar water heater is comprised of support, storage tank and thermal-collecting tube etc. usually, and it is the principle of utilizing hot water floating cold water to sink by thermal-collecting tube, makes the water generates microcirculation and reaches required hot water.
But, existing solar energy heat collection pipe consists of inside and outside two concentric circles glass tubes, cured being deposited on inner tube outer surface of selective absorption with high-absorbility and low-launch-rate forms absorber, between the inner and outer pipes interlayer, is pumped into high vacuum, and its shape is as an elongated inner flask.For guarantee between inside and outside body vacuum, usually need to the interbedded vacuum of inner and outer pipes, be measured with special testing tool.This mode not only operates inconvenience, and the wasting manpower and material resources.
So, for those skilled in the art, need thermal-collecting tube of the prior art is improved, more just the vacuum between the thermal-collecting tube inner and outer pipes can be detected, and can absorb more solar energy, improve the absorption transformation efficiency of solar energy.
Summary of the invention
The purpose of this utility model is to have the problems referred to above for existing technology, has proposed a kind of thermal-collecting tube, and this thermal-collecting tube has can observe vacuum quality and the good characteristics of endothermic effect between interior tube body and outer tube body.
The purpose of this utility model can realize by following technical proposal: a kind of thermal-collecting tube, comprise interior tube body and the outer tube body outside interior tube body, it is characterized in that, also be provided with clamp between described interior tube body and outer tube body, described outer tube body and interior tube body sealing are solidly fixed, and between outer tube body and interior tube body, be vacuum state, one end of described interior tube body has water inlet, the other end of interior tube body is blind end, scribble the thermal-arrest layer on the outer tube wall of described interior tube body, scribble the barium layer on the inwall of described outer tube body.
By between interior tube body and outer tube body, establishing clamp, just interior tube body and outer tube body can be fixed together, prevent that interior tube body from rocking in outer tube body.By be coated with the thermal-arrest layer on the outer tube wall of interior tube body, just can effectively improve the absorption efficiency of solar energy, prevent too much the scattering and disappearing of solar energy simultaneously.By be coated with barium layer, the vacuum that just can detect by an unaided eye between interior tube body and outer tube body on the inwall of outer tube body.
In above-mentioned thermal-collecting tube, described thermal-arrest layer is aln layer or aluminium lamination or stainless steel layer.Adopting the thermal-arrest layer that these materials are made all to have advantages of that thermal conductivity is good and thermal coefficient of expansion is little, is good heat shock resistance material.
In above-mentioned thermal-collecting tube, the length of described barium layer is 3cm-5cm.As preferably, the length of barium layer is elected 4cm as, for people, under the naked eyes state, just can observe vacuum between interior tube body and outer tube body good job.
In above-mentioned thermal-collecting tube, the thickness of described barium layer is 0.2um-0.5um.As preferably, the thickness of barium layer is 0.35um.
In above-mentioned thermal-collecting tube, described interior tube body and outer tube body all adopt glass material to make.
In above-mentioned thermal-collecting tube, described interior tube body and outer tube body are one-body molded by the mode of cast.
Compared with prior art, this thermal-collecting tube has the following advantages: the utility model by being coated with the barium layer on the inwall of outer tube body, the vacuum that just can detect by an unaided eye between interior tube body and outer tube body, by be coated with the thermal-arrest layer on the outer tube wall of interior tube body, just can effectively improve the absorption efficiency of solar energy, prevent too much the scattering and disappearing of solar energy simultaneously, and simple in structure, easily manufactured.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1, interior tube body; 2, outer tube body; 3, clamp; 4, water inlet; 5, thermal-arrest layer; 6, barium layer.
The specific embodiment
Be below specific embodiment of the utility model by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
As shown in Figure 1, a kind of thermal-collecting tube, comprise interior tube body 1 and the outer tube body outside interior tube body 12, also be provided with clamp 3 between interior tube body 1 and outer tube body 2, outer tube body 2 and interior tube body 1 sealing are solidly fixed, and between outer tube body 2 and interior tube body 1, be vacuum state, an end of interior tube body 1 has water inlet 4, and the other end of interior tube body 1 is blind end.By between interior tube body 1 and outer tube body 2, establishing clamp 3, just interior tube body 1 and outer tube body 2 can be fixed together, prevent that interior tube body 1 from rocking in outer tube body 2.
