Abstract
The invention relates to a solar heat collecting pipe for reinforcing heat exchange. The solar heat collecting pipe comprises a metal inner pipe, wherein threads or bulges are formed on the inner surface of the metal inner pipe. According to the solar heat collecting pipe, heat can be transferred to a medium fully under the enhanced heat exchange action of a metal thread pipe of the solar heat collecting pipe, so that the heat transfer efficiency and medium temperature are improved, the temperature of the pipe wall of the heat collecting pipe is more uniform, and the heat collecting pipe runs safely and reliably. The solar heat collecting pipe can be used for a solar groove type heat power generation technology and also can be used for a solar Fresnel power generation technology, the photo-thermal conversion efficiency of solar heat power generation is improved greatly.
Description
Technical field
The invention belongs to the solar light-heat power-generation technical field, be specifically related to a kind of enhanced heat exchange solar energy heat collection pipe.
Background technology
The energy resources reserves of China allow of no optimist, and per capita resources is not abundant.Many places lack the conventional energy resource resource, but solar energy resources is abundant.For improving solar energy thermal-power-generating efficient, the general employing on the one hand improved solar thermal collection system outlet medium temperature, thereby improves the thermoelectric conversion efficiency of whole system.Improve the performance and the thermal transition efficient of each assembly of solar energy thermal-power-generating, parts on the other hand.Be one of solar energy thermal-power-generating critical component, the measure that should primary study improves its efficient.Line-focusing solar energy vacuum heat-collecting pipe relates to multi-disciplinary high-tech product, receives the restriction of domestic technique development level and present situation.
The present thermal-collecting tube no matter outer surface of vacuum glass-metal vacuum thermal-collecting tube or antivacuum plated film collector metal pipe adopts the plated film coating to absorb the solar radiation energy; But their inner surface all adopts smooth surface; After the solar radiation heat mirror thermal-collecting tube heat conduction by the absorption of thermal-collecting tube outer metallic surface plated film coating; Have the fluid media (medium) (conduction oil, fused salt, water, steam) etc. of metallic interior surface and internal flow to carry out heat exchange, because of characteristics such as the solar energy energy-flux density are low, media flow speed is lower in the thermal-collecting tube; If factors such as inhomogeneous, hot transmission of absorption heat and convection properties are bad; Can cause thermal-collecting tube local heating and wall temperature difference increasing up and down, thermal-collecting tube produced damage, the equipment that influences normally moves.
And the thermal-collecting tube structure of other augmentation of heat transfers and form are comparatively complicated, and resistance height, manufacturing difficulty of processing and cost are big, are difficult for large-scale commercial applications and use.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the object of the present invention is to provide a kind of enhanced heat exchange solar energy heat collection pipe, utilize the augmentation of heat transfer effect, the medium that farthest heat is flowed in the metal inner pipe transfer tube.
In order to solve the problems of the technologies described above, the technical scheme that the present invention adopts is:
A kind of enhanced heat exchange solar energy heat collection pipe comprises metal inner pipe 1, and the inner surface of said metal inner pipe 1 has screw thread 2 or protruding 3.
Dispose glass outer tube 4 outside the said metal inner pipe 1, the outer surface of metal inner pipe 1 is coated with solar energy absorbing coating 5, vacuumizes between glass outer tube 4 and the metal inner pipe 1, forms vacuum glass-collector metal pipe.
The outer surface of said metal inner pipe 1 is coated with solar energy absorbing coating 5, forms antivacuum plated film collector metal pipe.
Said screw thread 2 in the form of a ring, and can have equally spaced protruding 3 in same annular in metal inner pipe 1.
Because the enhance heat transfer effect of the metal threaded pipe of solar energy heat collection pipe, the present invention can make heat fully pass to medium, has not only improved heat transference efficiency, improves medium temperature, can make the thermal-collecting tube tube wall temperature more even simultaneously, safe and reliable operation.Not only can be used for the hot generation technology of solar groove type, also can be used for the solar energy Fresnel generation technology, improve the photo-thermal transformation efficiency of solar energy thermal-power-generating greatly.
Description of drawings
Fig. 1 is vacuum glass of the present invention-collector metal duct ligation composition.
Fig. 2 is an antivacuum plated film collector metal duct ligation composition of the present invention.
The specific embodiment
Specify embodiment of the present invention below in conjunction with accompanying drawing and embodiment.
Embodiment one
As shown in Figure 1; A kind of enhanced heat exchange solar energy heat collection pipe comprises metal inner pipe 1, and the inner surface of said metal inner pipe 1 has screw thread 2; The metal inner pipe 1 outer glass outer tube 4 that disposes; The outer surface of metal inner pipe 1 is coated with solar energy absorbing coating 5, vacuumizes between glass outer tube 4 and the metal inner pipe 1, forms vacuum glass-collector metal pipe.Screw thread 2 in the form of a ring, has equally spaced protruding 3 in same annular in metal inner pipe 1.
Embodiment two
As shown in Figure 2, a kind of enhanced heat exchange solar energy heat collection pipe comprises metal inner pipe 1, and the inner surface of said metal inner pipe 1 has protruding 3, protruding 3 evenly to distribute, and the outer surface of metal inner pipe 1 is coated with solar energy absorbing coating 5, forms antivacuum plated film collector metal pipe.
Because the effect that the screw thread 2 that is provided with or protruding 3 has enhance heat transfer can make heat fully pass to medium, therefore can improve heat transference efficiency, improves medium temperature, can make the thermal-collecting tube tube wall temperature more even simultaneously, safe and reliable operation.
