Abstract
The utility model relates to a solar energy collector with vacuum heat collecting pipes and focusing an arc plate with asymptotic curvature. Focusing reflection plates with arc surfaces are arranged below the heat collecting pipes or on the left and the right sides of the heat collecting pipes. The high point of the focusing reflection plate is positioned under the heat collecting pipe. Acurvature radius is large at first and gradually becomes small. Protruded small wave crests are arranged below the vacuum heat collecting pipe. The aluminizing thin film of reflection of light is adhered to the arc surface of the reflection plate. The surface of a tail rack, which is toward the heat collecting pipe is the incline of reflection of light, which is made of bright metals or the aluminizing thin film of reflection of light. The utility model has the advantages of high heat efficiency, simple structure, and simple manufacture. The quantity of hot water production can be enhanced 20-40%.
Description
The utility model relates to a kind of vacuum heat-collecting tube solar cambered surface concentrating collector, belongs to the technical field of solar energy vacuum heat collecting device.
Existing solar energy heat collector is mainly by vacuum heat collection pipe (2) heat-preservation heat-collection case, reflecting plate, parts such as support are formed, its reflecting plate is dull and stereotyped, and most sunlight that shines on the reflecting plate through gap between each vacuum heat collection pipe can not be reflected on vacuum heat collection pipe, and light and heat collection efficient is low.
The purpose of this utility model is that a kind of vacuum heat-collecting tube solar cambered surface concentrating collector will be provided, and it can overcome above-mentioned shortcoming, and its reflecting plate changes the cambered surface light gathering baffle-board into, can significantly improve the efficient of reflective thermal-arrest.
The purpose of this utility model is achieved in that
In thermal-collecting tube (2) below or left and right sides the cambered surface light gathering baffle-board (3) of curved surface direction towards the vacuum heat collection pipe axis arranged, its high point (6) arrives the descending variation of bilge radius under the thermal-collecting tube (2).
The reflective metallized film of one deck (8) is pasted on cambered surface light gathering baffle-board (3) surface.
Heat-preservation heat-collection case (1) and tailstock (4) are reflective inclined-plane or the cambered surfaces of being made by bright metal or reflective metallized film towards the one side of vacuum heat collection pipe (2).
The little crest (7) that one projection is arranged under vacuum heat collection pipe (2).
Accompanying drawing 1, the schematic diagram of gradual change curvature cambered surface concentrating collector;
Accompanying drawing 2, the profile of gradual change curvature cambered surface light gathering baffle-board.
Now in conjunction with the accompanying drawings the structure of vacuum heat-collecting tube solar gradual change curvature cambered surface concentrating collector is described in detail.
By Fig. 1, heat-preservation heat-collection case (1) is positioned at the top of heat collector, one tailstock (4) is arranged at the bottom, support (5) is fixed in tailstock (4), between heat-preservation heat-collection case (1) and tailstock (4), several vacuum heat collection pipes (2) are housed, the column cambered surface light gathering baffle-board (3) of a curved surface direction towards the vacuum heat collection pipe axis are all arranged in every thermal-collecting tube (2) below or left and right sides.
By Fig. 2, the high point of its of cambered surface light gathering baffle-board (3) (6) radius of curvature Changing Pattern of minimum point under the thermal-collecting tube is descending, and the little crest (7) of a projection is arranged in the below of vacuum heat collection pipe (2).
High point (6) is between two vacuum heat collection pipes (2), and it surpasses each formed plane of vacuum tube axis highly slightly.
The little crest of projection, its peak point is pressed close to vacuum heat collection pipe.
This cambered surface light gathering baffle-board (3) is by bright metal or composite such as organic or FRIM; plastics or metal sheet are made; bright metal can be used in its surface; the also reflective metallized film of Pasting (8); (this film is the solar cooker proprietary material, is that mylar+vacuum aluminium coated layer+silicon dioxide layer of protection is formed).
Vacuum heat collection pipe (2) heat-preservation heat-collection case (1) and tailstock (4) are reflecting slant or the cambered surfaces of being made by bright metal or reflective metallized film towards the one side of vacuum heat collection pipe (2), sunlight is in the different time during work of this heat collector, a part of directly vacuum tube (2) directly absorbs on heat collector the time with different angular illumination, another partly just is radiated between two pipes (2) in the crack on the cambered surface reverberation (3), because cambered surface is towards each vacuum heat collection pipe and be the encirclement shape, so major part all reflects on vacuum collector (2), consider the effect of oblique fire, from crest to trough, descending radius of curvature Changing Pattern, also make curved surface can guarantee that the light of all angles all is reflected on the vacuum heat collection pipe (2) everywhere, under the bigger situation of oblique fire angle, the little crest of projection (7) of vacuum heat collection pipe (2) below has played secondary reflection again, avoid reverberation to leak effect between trough and thermal-collecting tube, because of face has improved the daylighting collecting efficiency significantly, make the heat production water yield can improve 20-40%.
Compared with prior art, vacuum manifold solar energy gradual change curvature cambered surface concentrating collector has following advantages:
1, adopts the cambered surface light gathering baffle-board, any time sunlight reflected is concentrated on the vacuum heat collection pipe by day, increase collecting efficiency.
2, the heat production water yield can improve 20-40%.
Claims (4)
