Technical field
The utility model relates to solar energy heat utilization field, is specifically related to a kind of solar airconditioning thermal-collecting tube.
Background technology
Solar energy heat collection pipe is to be the device of heat energy with light energy conversion, solar airconditioning is to utilize solar energy heat collection pipe that the energy-saving type air conditioner of the needed heat medium water of its generator is provided for Absorption Refrigerator, at present utilization more and more gets the nod, the coefficient of performance of refrigeration machine is higher, the refrigerating efficiency of air-conditioning system is also higher, so solar energy heat collection pipe plays very important effect in solar airconditioning.Vacuum type thermal-collecting tube commonly used is comprised of glass-vacuum tube, inner tube, attemperater etc., and the outer wall of inner tube is the solar energy coating, vacuumize between two pipes, with vacuum layer as thermal insulation layer.But general thermal-collecting tube temperature is difficult to surpass 100 degrees centigrade, so that the coefficient of performance of refrigeration machine can't raise, has greatly affected the serviceability of air-conditioning.
The utility model content
In order to address the above problem, the purpose of this utility model is to provide a kind of temperature can reach 400-500 degree centigrade and the simple solar airconditioning thermal-collecting tube of manufacture craft.
For achieving the above object, technical scheme that the utility model adopts is as follows:
A kind of solar airconditioning thermal-collecting tube, it comprises: glass outer tube and place metal U-shaped inner tube in the described glass outer tube; Described metal U-shaped inner tube blind end has collet and air-breathing locator; The open end of described glass outer tube arranges convective cooling pipe and attemperating unit.
Described convective cooling tube section is square, circular or other irregular shape.
Described metal U-shaped inner tube outer surface has the high efficiency selected absorber coatings.
Solar airconditioning thermal-collecting tube described in the utility model, its beneficial effect is:
At original solar energy heat collection pipe inner tube blind end collet and air-breathing locator have been installed, air-breathing locator can guarantee well that thermal-collecting tube absorbs and photo-thermal conversion efficiency the high efficiency of solar energy, collet can guarantee that inner tube high temperature can not be delivered to outer glass pipe, and energy can not run off.Interior metal tube external end head adds convective cooling pipe and attemperating unit, flow velocity or temperature by medium in the convective cooling pipe realize the operation of thermal-collecting tube high efficient and reliable, thereby improved the inner tube temperature, reduced heat loss, reduced the outer tube temperature, so that thermal-collecting tube is with optimum state work, temperature can reach 400-500 degree centigrade, be applied in the air-conditioning, the coefficient of refrigerating performance of air-conditioning is higher.In addition, greatly reduce the performance requirement to outer tube sealing-in metal material and glass material after the repacking, simplified production technology, under the prerequisite that improves heat-collecting temperature and thermal conversion efficiency, greatly reduce production cost.
Description of drawings
The picture that this description of drawings provides is used for auxiliary to further understanding of the present utility model, consists of the application's a part, does not consist of to improper restriction of the present utility model, in the accompanying drawings:
Accompanying drawing 1 is the utility model solar airconditioning thermal-collecting tube structural representation.
The specific embodiment
Describe the utility model in detail below in conjunction with accompanying drawing and specific implementation method, be used for explaining the utility model in schematic enforcement of the present utility model and explanation, but not as to restriction of the present utility model.
As shown in Figure 1, the utility model discloses a kind of solar airconditioning thermal-collecting tube, it comprises: glass outer tube 12 and place metal U-shaped inner tube 5 in the described glass outer tube; Described inner tube 5 outer surfaces have high efficiency selected absorber coatings 11, and described metal U-shaped inner tube blind end has one section pipe 6, and pipe 6 surfaces have collet 7 and air-breathing locator 8; The openend of described glass outer tube 12 connects annular or circular convective cooling pipe 3 and a temperature control blind pipe 10 by connecting gusset 1 and bearing plate 4.Convective cooling pipe 3 guarantees that by head piece 2,9 is carried out convection current inner tube high temperature can not be delivered to outer glass pipe, and energy can not run off.
The inner tube of thermal-collecting tube adopts metal U-shaped structure, but inner tube free wxpansion; Collet and air-breathing locator guarantee that inner tube high temperature can not be delivered to outer glass pipe, and energy can not run off.The flow velocity of medium or temperature realize the operation of thermal-collecting tube high efficient and reliable in the convective cooling pipe, thereby have improved the inner tube temperature, have reduced heat loss, have reduced the outer tube temperature, so that thermal-collecting tube is with optimum state work, temperature can reach 400-500 degree centigrade.
Solar airconditioning thermal-collecting tube described in the utility model, its beneficial effect is:
At original solar energy heat collection pipe inner tube blind end collet and air-breathing locator have been installed, air-breathing locator can guarantee well that thermal-collecting tube absorbs and photo-thermal conversion efficiency the high efficiency of solar energy, collet can guarantee that inner tube high temperature can not be delivered to outer glass pipe, and energy can not run off.Interior metal tube external end head adds convective cooling pipe and temperature control blind pipe, flow velocity or temperature by medium in the convective cooling pipe realize the operation of thermal-collecting tube high efficient and reliable, thereby improved the inner tube temperature, reduced heat loss, reduced the outer tube temperature, so that thermal-collecting tube is with optimum state work, temperature can reach 400-500 degree centigrade, be applied in the air-conditioning, the coefficient of refrigerating performance of air-conditioning is higher.In addition, greatly reduce the performance requirement to outer tube sealing-in metal material and glass material after the repacking, simplified production technology, under the prerequisite that improves heat-collecting temperature and thermal conversion efficiency, greatly reduce production cost.
