Abstract
The utility model provides a heat collection pipe in a solar collector, and belongs to the technical field of solar energy. The heat collection pipe in the solar collector resolves the technical problem that an existing heat collection pipe is easily broken in winter. The heat collection pipe in the solar collector comprises an inner pipe body and an outer pipe body, wherein the inner pipe body and the outer pipe body are fixedly connected into a whole in a sealed mode, the position between the inner pipe body and the outer pipe body is in a vacuum state, the upper end and the lower end of the inner pipe body and the upper end and the lower end of the outer pipe body are all sealed ends, the inner pipe body is formed by an inner pipe body upper section and an inner pipe body lower section, the outer pipe body is formed by an outer pipe body upper section and an outer pipe body lower section, a heat collection coating film is uniformly coated on the outer wall of the inner pipe body lower section, and superconduction liquid is further contained in the inner pipe body. The heat collection pipe in the solar collector has the advantages of being high in low-temperature resistant performance, wider in application range and the like.
Description
Technical field
The utility model belongs to technical field of solar, relates to a kind of thermal-collecting tube, particularly the thermal-collecting tube in a kind of solar thermal collector.
Background technology
Existing thermal-collecting tube comprises the two-layer inner and outer tubes of being made by glass material, between inner and outer tubes, is vacuum state, scribbles the thermal-arrest film plating layer on the outer wall of inner tube, in the inner tube the inside, water also is housed, and inner tube one end is the connection end for being connected with water tank.Due to water being housed in inner tube, when temperature is too low, water can build-up ice, and thermal-collecting tube can't be worked, simultaneously, after freezing, inner tube is easily broken, once the inner tube fragmentation, water in water tank also can constantly flow out, and causes great waste, the serious water damage accident that even causes.
Summary of the invention
The purpose of this utility model is to have the problems referred to above for existing technology, has proposed the thermal-collecting tube in a kind of solar thermal collector, and this thermal-collecting tube has the characteristics low temperature resistant, that the scope of application is wide.
The purpose of this utility model can realize by following technical proposal: the thermal-collecting tube in a kind of solar thermal collector, comprise interior tube body and outer tube body, it is characterized in that, described interior tube body and outer tube body sealing are solidly fixed, and between interior tube body and outer tube body, be vacuum state, the two ends up and down of described interior tube body and the two ends up and down of outer tube body are sealed end, described interior tube body is comprised of interior tube body epimere and interior tube body hypomere, described outer tube body is comprised of outer tube body epimere and outer tube body hypomere, evenly scribble the thermal-arrest film plating layer on the outer wall of described interior tube body hypomere, also be provided with superconducting fluid in described interior tube body.
The length of described interior tube body hypomere is greater than the length of described interior tube body epimere.
The length ratio of the length of described interior tube body hypomere and interior tube body epimere is 7:1.
Described thermal-arrest film plating layer is aln layer or aluminium lamination or stainless steel layer.
The thickness of described thermal-arrest film plating layer is 0.1um-0.2um.
Described interior tube body and outer tube body all adopt glass material to make.
Described interior tube body and outer tube body are one-body molded by the mode of cast.
Compared with prior art, the utility model is by being provided with superconducting fluid in interior tube body, make this thermal-collecting tube can in the situation that subzero 30 ° continue to use, resistance to low temperature is strong, the scope of application is wider.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1, interior tube body; 11, interior tube body epimere; 12, interior tube body hypomere; 2, outer tube body; 21, outer tube body epimere; 22, outer tube body hypomere; 3, thermal-arrest film plating 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, thermal-collecting tube in a kind of solar thermal collector, comprise interior tube body 1 and outer tube body 2, described interior tube body 1 and outer tube body 2 sealings are solidly fixed, and be vacuum state between interior tube body 1 and outer tube body 2, the two ends up and down of described interior tube body 1 and the two ends up and down of outer tube body 2 are sealed end, described interior tube body 1 is comprised of interior tube body epimere 11 and interior tube body hypomere 12, described outer tube body 2 is comprised of outer tube body epimere 21 and outer tube body hypomere 22, evenly scribble thermal-arrest film plating layer 3 on the outer wall of described interior tube body hypomere 12, also be provided with superconducting fluid in described interior tube body 1.
Superconducting fluid is the existing product that market can have been bought, and such as the superconducting fluid that ease extra large dark blue science and technology limited Company in Beijing is produced, the concrete composition of superconducting fluid is not described in detail in this example.
In the present embodiment, the length of described interior tube body hypomere 12 is greater than the length of described interior tube body epimere 11, concrete, and the length ratio of the length of described interior tube body hypomere 12 and interior tube body epimere 11 is 7:1, and such design can improve Heat-collecting effect.
