Referring to fig. 1 to 7, an embodiment of the utility model provides a composite multi-curved-surface concentrator capable of adjusting heat collection, which includes a body 10 and an air inlet assembly 20, wherein the body 10 is provided with an accommodating cavity 110, and the body 10 is provided with an air inlet 120 and an air outlet 130 communicated with the accommodating cavity 110; the air intake assembly 20 comprises a fan assembly 210, a light transmission pipe 30 communicated with the fan assembly 210 is arranged in the accommodating cavity 110, and two ends of the light transmission pipe 30 are communicated with the air inlet 120 and the air outlet 130; a light-reflecting ventilation pipe 330 with a plurality of magnetic suction heads 310 attached to the surface is arranged in the light-transmitting pipe 30, a photothermal conversion fin 320 connected with the magnetic suction heads 310 is arranged on the outer peripheral wall of the light-reflecting ventilation pipe 330, and a light-reflecting coating 3210 and a selective absorbing coating 3220 arranged opposite to the light-reflecting coating 3210 are arranged on the photothermal conversion fin 320; wherein, in the state of air intake of the light-transmitting tube 30, one end of the photothermal conversion fin 320 is blown away from the magnetic attraction head 310 and rotates around one end of the magnetic attraction head 310 towards the inner wall surface of the light-transmitting tube 30, and the selective absorbing coating 3220 faces the light intake side far away from the reflective ventilation tube 330; in the non-air intake state of the light pipe 30, the photothermal conversion fin 320 is attached to the outer wall surface of the light reflecting ventilation pipe 330, and the light reflecting coating 3210 faces the light intake side of the accommodating chamber 110.
Referring to fig. 1, when the fan assembly 210 is in an operating state and flowing air passes through the inner cavity of the light transmitting tube 30, one end of the photothermal conversion fin 320 is separated from the reflective ventilation tube 330 and rotates toward the inner wall surface of the light transmitting tube 30, so that air flows through the inner cavity of the light transmitting tube 30 and also partially flows through the reflective ventilation tube 330, and thus the air can fully contact with the photothermal conversion fin 320, so as to prolong the heat exchange time between the air and the photothermal conversion fin 320, the selective absorption coating 3220 arranged on the photothermal conversion fin 320 absorbs heat of light and transfers the heat to the flowing air, and the heated air is discharged to an external functional system through the air outlet 130.
Referring to fig. 2 to 4, in a possible embodiment of the present invention, a gas passage 3110 communicated with the inner cavity of the light-transmitting tube 30 is disposed inside the reflective ventilation tube 330, a plurality of flow guide grooves 3120 communicated with the gas passage 3110 are disposed on the surface of the reflective ventilation tube 330, and the flow guide grooves 3120 are spirally arranged; the plurality of photothermal conversion fins 320 are arranged at intervals in the axial direction of the light reflecting ventilation pipe 330, and the connecting line of the connecting ends of the plurality of photothermal conversion fins 320 and the light reflecting ventilation pipe 330 is spiral and is arranged in the same direction as the rotation direction of the flow guide groove 3120. It should be noted that the light-transmitting tube 30 is a single-layer light-transmitting tube, and the light-transmitting tube 30 is provided with an inner cavity, the inner cavity is used for gas circulation, the reflective ventilation tube 330 is disposed in the inner cavity, a gas flow channel 3110 communicated with the inner cavity is disposed inside the reflective ventilation tube 330, when the fan assembly 210 has flowing gas into the light-transmitting tube 30 through the air inlet 120, a part of the flowing gas flows toward the air outlet 130 through the inner cavity, and the other part of the flowing gas passes through the gas flow channel 3110 and is guided to the inner cavity through the flow guide groove 3120. That is, when the gas circulates in the inner cavity, the guiding groove 3120 is spiral, and then the photothermal conversion fin 320 is blown to rotate around one end of the magnetic attraction head 310 along with the gas transmitted through the gas passage 3110, so that one end of the photothermal conversion fin 320 is separated from the reflective ventilation pipe 330 and rotates toward the inner side wall of the light transmission pipe 30. It is understood that the reflective ventilation pipe 330 is rotatably connected to the main body 10, so that when the reflective ventilation pipe 330 rotates, the photothermal conversion fins 320 near the air inlet 120 also rotate, which promotes the ends of the photothermal conversion fins 320 far away from the air inlet 120 to gradually separate from the magnetic attraction head 310, and finally causes the ends of all the photothermal conversion fins 320 to separate from the magnetic attraction head 310 and rotate with the magnetic attraction head 310, and particularly, for the rotational connection between the reflective ventilation pipe 330 and the main body 10, a socket connection or the like may be selected, which is not limited herein.
In an embodiment of the present invention, the light-transmitting tube 30 is replaced by a single-layer tube, which reduces the manufacturing cost of the light-transmitting tube 30, and can realize the switching between the photo-thermal direct conversion and the reflective overheat-proof self-protection, thereby ensuring the service life of the photo-thermal conversion receiver composed of the light-transmitting tube 30 and the reflective ventilation tube 330.
Referring to fig. 3 to 5, in an embodiment of the utility model, a magnetic attraction portion (not shown) is disposed on a surface of the reflective ventilation tube 330 near the photothermal conversion fin 320, so that the selective absorption coating 3220 on the photothermal conversion fin 320 is attached to the magnetic attraction portion when the light transmission tube 30 is in a non-air intake state. The magnetic attraction portion is disposed so that the photothermal conversion fin 320 is restored to the state of being attached to the magnetic attraction head 310 in the non-air intake state, and the selective absorption coating 3220 is protected from being damaged by overheating due to light irradiation, so that the selective absorption coating 3220 is attached to the surface of the reflective ventilation pipe 330. In other possible embodiments, a retaining groove may be formed on the surface of the reflective vent tube 330, so that the selectively absorbing coating 3220 can be restored into the retaining groove without being blown by the flowing gas. The limiting groove can be coated with magnetic materials, so that the photothermal conversion fin 320 can move towards the limiting groove in a state of not being blown by flowing gas.
For the body 10, a top frame 140 and a transparent cover plate 150 connected to the top frame 140 are disposed on the top of the body 10, and the transparent cover plate 150 is disposed in the accommodating cavity 110. In a possible embodiment of the present invention, the transparent cover plate 150 is a double-layer glass cover plate, and a thermal insulation cavity is disposed in the middle of the double-layer glass cover plate. The light-transmitting cover plate 150 is used for sealing the sealed cavity, and after light irradiates the light-transmitting tube 30 through the double-layer glass cover plate, the double-layer glass cover plate can reduce the exchange between heat in the accommodating cavity 110 and the outside. In other possible embodiments, the transparent cover plate 150 may also be a double-layer PC cover plate, and a thermal insulation cavity is also disposed between the double-layer PC cover plate, which is not limited herein.
Referring to fig. 5 to 7, two sidewalls of the accommodating cavity 110 parallel to the axial direction of the light-transmitting tube 30 sequentially include along a direction from the end close to the light-transmitting cover plate 150 to the direction toward the light-transmitting tube 30: the first reflective surface 1110, the second reflective surface 1120 connected to the first reflective surface 1110, and the third reflective surface 1130 connected to the second reflective surface 1120, wherein the first reflective surface 1110, the second reflective surface 1120, and the third reflective surface 1130 are used for reflecting light passing through the light-transmitting cover plate 150 and guiding the light toward the light-transmitting tube 30. That is, the accommodating cavity 110 may be symmetrically disposed on two opposite sides of the light-transmitting tube 30, and one side includes a first reflective surface 1110, a second reflective surface 1120, and a third reflective surface 1130 connected in sequence. In a possible embodiment of the present invention, the first reflective surface 1110 and the third reflective surface 1130 are both parabolic curved surfaces, the second reflective surface 1120 is a plane, the second reflective surface 1120 is parallel to the axial direction of the light reflecting ventilation tube 330, and the third reflective surface 1130 is at least partially located below the light transmitting tube 30.
For example, referring to fig. 5, in practical applications, the accommodating cavity 110 may receive incident sunlight with a solar altitude variation range of 0-40 degrees, and may also improve the average heat collection of the heat-adjustable compound multi-curved surface condenser according to seasonal adjustment.
When the light is irradiated to the first reflective surface 1110 through the transparent cover 150, most of the light is reflected toward the transparent tube 30 because the first reflective surface 1110 is a parabolic curved surface, and thus more light can be irradiated to the transparent tube 30 after being reflected. For the light irradiated to the second reflecting surface 1120, the second reflecting surface 1120 is a plane and is parallel to the axis of the light-transmitting tube 30, so that the light can be directly reflected to the light-transmitting tube 30 or reflected to the light-transmitting tube 30 through the third reflecting surface 1130. For the light irradiated to the third reflecting surface 1130, because the third reflecting surface 1130 is close to the bottom of the light-transmitting tube 30 and is disposed in a parabolic curved surface, most of the reflected light passes through the bottom region of the light-transmitting tube 30 toward the top of the accommodating cavity 110. For example, referring to fig. 5, when the light ray a irradiates the third reflective surface 1130, it is reflected to the light-transmitting tube 30, and the light rays b and c are two end points of the first reflective surface 1110, and both the light rays b and c can be reflected to the light-transmitting tube 30. Most of the light in the region between the light b and the light c may reach the light-transmitting tube 30 after being reflected. Fig. 6 also shows that when the photothermal conversion fin 320 is adhered to the light transmitting tube 30, light rays do not pass through the reflective vent tube 330 except for the portion of the light rays directly reaching the reflective vent tube 330, and thus an overheating reaction at the outer surface of the reflective vent tube 330 can be prevented. In addition, at this time, the optional coating side of the photothermal conversion fin 320 disposed on the magnetic attraction head 310 is attached to the surface of the light reflecting ventilation pipe 330, and the light reflecting coating 3210 is disposed on the side away from the outer surface of the light reflecting ventilation pipe 330, so that part of the light can be reflected, and the photothermal conversion fin 320 is prevented from being damaged due to overheating.
The air intake assembly 20 further includes an air guide pipe 220 connected to the fan assembly 210, a connection sleeve 230 connected to the main body 10 is disposed on one side of the air guide pipe 220, and the connection sleeve 230 is connected to the air inlet 120 or the air outlet 130. In a possible embodiment of the present invention, the connection sleeve 230 is used to connect the air duct 220 and the light-transmitting tube 30. Both ends of the light-transmitting tube 30 can extend to the air inlet 120 and the air outlet 130, so that the connection sleeve 230 is directly adhered to the outer side wall of the body 10 near the air inlet 120, and the other side of the connection sleeve 230 is connected to the air-guiding tube 220.
For the reflective ventilation tube 330, two ends of the reflective ventilation tube 330 are respectively provided with a clamping column 3140, the length of the clamping column 3140 is consistent with the diameter of the inner cavity of the light-transmitting tube 30, so that two ends of the clamping column 3140 can be abutted against the side wall of the inner diameter of the light-transmitting tube 30, and the connecting end of the reflective ventilation tube 330 and the clamping column 3140 is positioned in the middle of the clamping column 3140, so that the reflective ventilation tube 330 can be positioned in the center of the inner cavity of the light-transmitting tube 30 when the clamping column 3140 is abutted against the side wall of the light-transmitting tube 30. Two locking posts 3140 are disposed near the air inlet 120 and the air outlet 130, respectively, to prevent the magnetic attraction head 310 from moving back and forth inside the light-transmitting tube 30.
Referring to fig. 1, 2 and 7, in a possible embodiment of the present invention, a plurality of bodies 10 may be arranged in series or in parallel, and each fan assembly 210 may be connected to at least one body 10. For example, referring to fig. 2, two bodies 10 may be arranged in series, and the two bodies 10 are connected by an air duct 220. That is, one body 10 may be connected by one fan assembly 210, but both bodies 10 may be in an air intake state at the same time. Alternatively, two bodies 10 may be arranged in parallel, for example, referring to fig. 7, two bodies 10 arranged in parallel may be simultaneously filled with the moving air by one fan assembly 210.
To sum up, in the composite multi-curved-surface concentrator capable of adjusting heat collection provided by the embodiment of the utility model, when the light transmission tube 30 is in an air intake state, one end of the photothermal conversion fin 320 is separated from the reflective ventilation tube 330, and the selective absorbing coating 3220 faces the light intake side of the light transmission tube 30, absorbs heat and transmits the heat to the inner cavity of the light transmission tube 30, and when the light transmission tube 30 is in a non-air intake state, one side of the selective absorbing coating of the photothermal conversion fin 320 is attached to the surface of the reflective ventilation tube 330, so that an overheat reaction is prevented from forming on one side of the selective absorbing coating of the photothermal conversion fin 320, and the service life of the photothermal conversion fin 320 is shortened.
