Description

Technical Field

[0001] The present invention relates to the technical field of street lamps, in particular to a street lamp with a rapid heat dissipation function. Background Art

[0002] Solar street lights powered by photovoltaic panels are widely used in daily life. As the price of photovoltaic panel materials drops, solar street lights have advantages that other energy sources do not have, such as cleanliness and safety; photovoltaic panels themselves also have certain defects.

[0003] In the daily use of street lamps, they need to be cooled down quickly to prevent them and photovoltaic panels from exploding due to excessive temperature rise. Among the existing heat dissipation technologies, air cooling is less efficient and is affected by environmental factors. Liquid cooling mostly uses refrigerants to absorb and conduct heat. Keeping the refrigerant in a high temperature environment for a long time will reduce the thermal conductivity of the refrigerant. Summary of the Invention

[0004] The object of the present invention is to provide a street lamp with a rapid heat dissipation function to solve the problems in the prior art.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: A street lamp with rapid heat dissipation function includes a lamp holder, a lamp pole, a lamp frame, a hinged seat, a photovoltaic panel, a lamp group and a heat dissipation mechanism. The lamp pole is fixedly connected to the lamp holder and the lamp frame, the lamp frame is fixedly connected to the hinged seat and the lamp group, the hinged seat is hinged to the photovoltaic panel, the lamp frame is fixedly connected to the heat dissipation mechanism, and a grille is provided on the lamp frame, which is in contact with the heat dissipation mechanism.

[0006] This street lamp is a new type of environmentally friendly street lamp that generates electricity through solar energy. The street lamp converts solar energy into electrical energy through photovoltaic panels to power the street lamp and the heat dissipation mechanism. The heat dissipation branches on the heat dissipation mechanism are in contact with the grilles on the lamp frame respectively. By dividing the lamp group into equal parts horizontally, the heat dissipation mechanism can quickly cool the lamp groups in the equal parts horizontally, increase the heat dissipation efficiency of the corresponding position in the overheated area of ​​the lamp group, and at the same time, the heat dissipation mechanism can also dissipate heat from the photovoltaic panels.

[0007] Furthermore, the heat dissipation mechanism includes a mounting frame, a heat exchange tube, a main outer tube, an air cooling mechanism, a main inner tube and a pump. The mounting frame is fixedly connected to the lamp bracket, the main outer tube, the air cooling mechanism and the pump. The air cooling mechanism is connected to the main outer tube and the main inner tube through pipes. The heat exchange tube is connected to the main outer tube and the main inner tube through pipes. Several groups of heat exchange tubes are provided, and several groups of heat exchange tubes are linearly distributed along the axis of the main outer tube. The heat exchange tubes are in contact with the grille, and the air cooling mechanism is connected to the pump through pipes.

[0008] Several groups of heat exchange tubes are in contact with the grille, and the heat-absorbing refrigerant in the heat exchange tubes absorbs the heat from the photovoltaic panels and the lamp groups. After absorbing the heat, the refrigerant in the heat exchange tubes passes through the internal pipeline into the main inner tube under the action of the pump. The refrigerant carrying heat enters the air cooling mechanism to complete the exchange of refrigerant and air for heat dissipation. After the heat dissipation is completed, the refrigerant flows back to the main outer tube under the action of the pump. The heat exchange tubes adjust the refrigerant flow rate returning from the main outer tube to each heat exchange tube according to the heat absorbed by the refrigerant flowing into the main inner tube, so as to achieve the effect of distributing more refrigerant to the heat exchange tubes in the overheating area of ​​the corresponding lamp group.

[0009] Furthermore, the heat exchange tube includes an outer heat exchange tube, an inner heat exchange tube, a one-way mechanism and a flow mechanism. The outer heat exchange tube is connected to the main outer tube through a pipe, and the inner heat exchange tube is connected to the main inner tube through a pipe. A first through hole and an annular groove are provided on the inner heat exchange tube. The first through hole is provided on the inner heat exchange tube away from one end of the main inner tube. There are several groups of first through holes and one-way mechanisms, and several groups of one-way mechanisms are fixedly connected to the first through holes. The annular groove is provided on the inner heat exchange tube close to one end of the main inner tube. The flow mechanism is fixedly connected to the annular groove, and the flow mechanism is in contact with the outer heat exchange tube.

[0010] After the refrigerant in the heat exchange outer tube absorbs heat from the photovoltaic panels and lamp groups, the pump generates negative pressure in the heat exchange inner tube. The refrigerant enters the heat exchange inner tube through the one-way mechanism. Under the action of negative pressure, the refrigerant flows to the flow mechanism. The flow mechanism adjusts the refrigerant flow rate from the main outer tube to each heat exchange outer tube according to the temperature of the refrigerant.

[0011] Furthermore, the one-way mechanism includes an outer tube, a top hole wall, a sealing bead, a first spring and a bottom hole plate. The outer tube is fixedly connected to the first through hole, the top hole wall and the bottom hole plate are fixedly connected to the outer tube, the first spring is fixedly connected to the sealing bead and the bottom hole plate, and the sealing bead is in contact with the top hole wall.

[0012] Due to the negative pressure in the heat exchange inner tube, the refrigerant between the heat exchange outer tube and the heat exchange inner tube pushes the sealing beads to move toward the bottom hole plate under the action of negative pressure, and the refrigerant in the heat exchange outer tube flows into the heat exchange inner tube through the gap between the top hole wall and the sealing beads. When the pump stops working, there is no negative pressure in the heat exchange inner tube, and the sealing beads re-contact the top hole wall under the action of the first spring to restore the deformation, so that the heat exchange outer tube and the heat exchange inner tube are sealed and isolated.

[0013] Furthermore, the flow mechanism includes a first annular shell, an I-shaped ring frame, a second spring and a connecting plate. The first annular shell is fixedly connected to the annular groove, the I-shaped ring frame is slidingly connected to the first annular shell, the first annular shell is provided with an outer annular opening, the outer annular opening is provided on the side of the first annular shell away from the first through hole, the I-shaped ring frame is close to the first through hole and is surrounded by the first annular shell to form an air cavity, the second spring is fixedly connected to the first annular shell and the I-shaped ring frame, the connecting plate is fixedly connected to the I-shaped ring frame, the connecting plate is provided with an inner tooth groove, and the inner tooth groove tooth pair is linearly evenly distributed along the axis of the connecting plate.

[0014] The refrigerant enters the heat exchange inner tube through the one-way mechanism. Under the action of negative pressure, the refrigerant flows to the annular groove. When the refrigerant passes through the first annular shell, the temperature rises according to the amount of heat absorbed by the refrigerant. The temperature-sensitive gas in the air cavity between the I-shaped ring frame and the first annular shell expands to different degrees due to heat. The I-shaped ring frame slides along the first annular shell, pushing the internal tooth surface on the connecting plate to engage the transmission gear.

[0015] Furthermore, the flow mechanism also includes a second annular shell, a transmission gear, a first tooth surface plate, a gear ring and a vane mechanism. The second annular shell is fixedly connected to the heat exchange inner tube and is arranged on the second annular shell near the center of the circle. The transmission gear is meshed with the tooth surface of the inner tooth groove. The first tooth surface plate is fixedly connected to the transmission gear. The second annular shell is provided with a second through hole and an inner ring rail. The first tooth surface plate is rotatably connected to the inner ring rail. The gear ring is rotatably connected to the second annular shell. The gear ring is provided with inner ring teeth and outer ring teeth. The first tooth surface plate is meshed with the tooth surface of the inner ring teeth. The second through holes are provided in several groups, and the several groups of second through holes are evenly distributed along the circumference of the outer edge of the second annular shell. The vane mechanism is rotatably connected to the second through hole, and the vane mechanism is meshed with the tooth surface of the outer ring teeth.

[0016] The inner tooth groove surface on the connecting plate meshes with the transmission gear. When the connecting plate moves horizontally away from the first ring shell, it drives the transmission gear to rotate. The transmission gear is fixedly installed with the first tooth surface plate, and the first tooth surface plate meshes with the inner ring tooth surface on the gear ring. The transmission gear transmits torque to the gear ring, and the teeth rotate around the center of the second ring shell to transmit torque to the vane mechanism. In the initial state, several groups of vane mechanisms are arranged horizontally with the cross section of the second ring shell. As the temperature-sensitive gas in the air cavity expands due to heat, it pushes the connecting plate, and transmits torque to the vane mechanism through the transmission gear and the gear ring. The gap between the rotation of several groups of vane mechanisms and the heat exchange outer tube increases, and the flow rate of refrigerant flowing back from the main outer tube to each heat exchange outer tube increases. The heat exchange and heat dissipation capacity of this heat exchange outer tube for the overheating area corresponding to the lamp group is enhanced, thereby achieving the function of distributing refrigerant areas and regulating the heat dissipation effect.

[0017] Furthermore, the blade mechanism includes a second tooth surface disk, a connecting column and a fan blade. The connecting column is fixedly connected to the second tooth surface disk and the fan blade. The connecting column is rotatably connected to the second through hole. The second tooth surface disk is meshed with the tooth surface of the outer ring gear.

[0018] The second tooth surface plate is meshed with the outer ring tooth surface on the gear ring, and the torque is transmitted to the second tooth surface plate through the rotation of the gear ring. The connecting column drives the fan blades to rotate around the axis of the second through hole, and the gap between the fan blade heat exchange outer tubes increases, and the flow rate of refrigerant flowing back from the main outer tube to each heat exchange outer tube increases.

[0019] Furthermore, the air cooling mechanism includes a driving fan, an outer curved pipe, an inner curved pipe and a one-way ball valve. The driving fan and the outer curved pipe are fixedly connected to the mounting frame, the outer curved pipe is connected to the main outer pipe through a pipe, the inner curved pipe is connected to the main inner pipe through a pipe, the one-way ball valve is fixedly connected to the inner curved pipe, the one-way ball valve is located on the end of the inner curved pipe away from the main inner pipe, and the pump is connected to the end of the inner curved pipe away from the main inner pipe through a pipe.

[0020] The refrigerant that has absorbed the heat from the lamp group enters the main inner tube from the heat exchange inner tube and passes into the inner curved tube. Under the action of the negative pressure provided by the pump, the refrigerant flows into the outer curved tube through the one-way ball valve at the end of the inner curved tube away from the main inner tube, driving the fan to simultaneously perform air cooling on the refrigerant in the outer curved tube and the inner curved tube, so that heat exchange occurs between the refrigerant and the air. After the outer curved tube, it flows back to each heat exchange outer tube through the main outer tube and the flow mechanism, completing a working process and continuing to quickly dissipate heat for the lamp group and photovoltaic panels.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention designs a heat dissipation mechanism, which divides the lamp group into equal parts horizontally, and adjusts the refrigerant flow rate of the main outer tube to each heat exchange outer tube according to the temperature absorbed by the refrigerant in the heat exchange tube at the corresponding position, when the temperature of the corresponding area is overheated, the refrigerant flow rate of the main outer tube backflowing to each heat exchange outer tube is increased, and the heat exchange and heat dissipation capacity of the heat exchange outer tube for the overheated area corresponding to the lamp group is enhanced, thereby achieving the function of allocating refrigerant areas to regulate the heat dissipation effect; the present invention designs a flow mechanism, and the refrigerant enters the heat exchange inner tube through a one-way mechanism. Under the action of negative pressure, the refrigerant flows to the annular groove. According to the amount of heat absorbed by the refrigerant, the temperature-sensitive gas in the air cavity expands to different degrees due to heat, and the I-shaped ring frame slides along the first ring shell, pushing the inner tooth groove tooth surface on the connecting plate to mesh with the transmission gear, driving the transmission gear to rotate, and the first tooth surface disk meshes with the inner ring tooth surface, transmitting torque to the gear ring, and the gear rotates around the center of the second ring shell. The transmission blade mechanism, in the initial state, several fan blades are arranged horizontally with the cross section of the second annular shell. As the temperature-sensitive gas in the air cavity expands due to heat, the gaps between several groups of fan blades and the heat exchange outer tubes increase, and the flow rate of refrigerant flowing back from the main outer tube to each heat exchange outer tube increases; the present invention designs an air cooling mechanism to quickly dissipate heat from the refrigerant, and the refrigerant that has absorbed the heat enters the main inner tube from the heat exchange inner tube and passes into the inner curved tube. Under the action of the negative pressure provided by the pump, the refrigerant flows into the outer curved tube through the one-way ball valve, driving the fan to simultaneously perform air cooling and heat dissipation on the refrigerant in the outer curved tube and the inner curved tube, so that heat exchange occurs between the refrigerant and the air; the present invention combines liquid cooling and air cooling to divide the lamp group into several areas. According to the heating conditions of the regional temperature, when the total amount of refrigerant is fixed, the proportion of refrigerant allocated to the heat exchange tube in the overheating area is increased, thereby increasing the heat dissipation efficiency of the overheating area.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] like Figure 1 、 Figure 2 As shown, the present invention provides a technical solution for a street lamp with a rapid heat dissipation function: it includes a lamp holder 1, a lamp pole 2, a lamp frame 3, a hinged seat 4, a photovoltaic panel 5, a lamp group 6 and a heat dissipation mechanism 7, the lamp pole 2 is fixedly connected to the lamp holder 1 and the lamp frame 3, the lamp frame 3 is fixedly connected to the hinged seat 4 and the lamp group 6, the hinged seat 4 is hinged to the photovoltaic panel 5, the lamp frame 3 is fixedly connected to the heat dissipation mechanism 7, and a grille 31 is provided on the lamp frame 3, and the grille 31 is in contact with the heat dissipation mechanism 7.

[0034] This street lamp is a new type of environmentally friendly street lamp that generates electricity through solar energy. The street lamp converts solar energy into electrical energy through the photovoltaic panel 5 to power the street lamp and the heat dissipation mechanism 7. The heat dissipation branches on the heat dissipation mechanism 7 are respectively in contact with the grilles 31 on the lamp frame 3. By dividing the lamp group 6 into horizontal equal parts, the heat dissipation mechanism 7 can quickly cool the horizontally divided lamp group 6, increase the heat dissipation efficiency of the corresponding position in the overheated area of ​​the lamp group 6, and at the same time, the heat dissipation mechanism 7 can also dissipate heat from the photovoltaic panel 5.

[0035] like Figure 1 、 Figure 2 、 Figure 3 As shown, the heat dissipation mechanism 7 includes a mounting frame 71, a heat exchange tube 72, a main outer tube 73, an air cooling mechanism 74, a main inner tube 75, and a pump 76. The mounting frame 71 is fixedly connected to the lamp holder 3, the main outer tube 73, the air cooling mechanism 74, and the pump 76. The air cooling mechanism 74 is connected to the main outer tube 73 and the main inner tube 75 through a pipe. The heat exchange tube 72 is connected to the main outer tube 73 and the main inner tube 75 through a pipe. There are several groups of heat exchange tubes 72, and the several groups of heat exchange tubes 72 are linearly distributed along the axis of the main outer tube 73. The heat exchange tubes 72 are in contact with the grille 31, and the air cooling mechanism 74 is connected to the pump 76 through a pipe.

[0036] Several groups of heat exchange tubes 72 are in contact with the grille 31, and the heat from the photovoltaic panels 5 and the lamp group 6 is absorbed by the heat-absorbing refrigerant in the heat exchange tubes 72. After absorbing the heat, the refrigerant in the heat exchange tubes 72 is passed into the main inner tube 75 through the internal pipeline under the action of the pump 76. The refrigerant carrying heat enters the air cooling mechanism 74 to complete the exchange and heat dissipation between the refrigerant and the air. After the heat dissipation is completed, the refrigerant flows back to the main outer tube 73 under the action of the pump 76. The heat exchange tubes 72 adjust the refrigerant flow rate returning from the main outer tube 73 to each heat exchange tube 72 according to the heat absorbed by the refrigerant flowing into the main inner tube 75, so as to achieve the effect of distributing more refrigerant to the heat exchange tubes 72 in the overheating area of ​​the corresponding lamp group 6.

[0037] like Figure 4 、 Figure 5 As shown, the heat exchange tube 72 includes a heat exchange outer tube 721, a heat exchange inner tube 722, a one-way mechanism 723 and a flow mechanism 724. The heat exchange outer tube 721 is connected to the main outer tube 73 through a pipeline, and the heat exchange inner tube 722 is connected to the main inner tube 75 through a pipeline. The heat exchange inner tube 722 is provided with a first through hole 7221 and an annular groove 7222. The first through hole 7221 is provided on the heat exchange inner tube 722 away from the end of the main inner tube 75. The first through hole 7221 and the one-way mechanism 723 are provided in several groups. Several groups of one-way mechanisms 723 are fixedly connected to the first through hole 7221. The annular groove 7222 is provided on the heat exchange inner tube 722 close to the end of the main inner tube 75. The flow mechanism 724 is fixedly connected to the annular groove 7222, and the flow mechanism 724 is in contact with the heat exchange outer tube 721.

[0038] After the refrigerant in the heat exchange outer tube 721 absorbs the heat from the photovoltaic panel 5 and the lamp group 6, the pump 76 generates negative pressure in the heat exchange inner tube 722, and the refrigerant enters the heat exchange inner tube 722 through the one-way mechanism 723. Under the action of the negative pressure, the refrigerant flows to the flow mechanism 724. The flow mechanism 724 adjusts the refrigerant flow rate from the main outer tube 73 to each heat exchange outer tube 721 according to the temperature of the refrigerant.

[0039] like Figure 6 As shown, the one-way mechanism 723 includes an outer cylinder 7231, a top hole wall 7232, a sealing bead 7233, a first spring 7234 and a bottom hole plate 7235. The outer cylinder 7231 is fixedly connected to the first through hole 7221, the top hole wall 7232 and the bottom hole plate 7235 are fixedly connected to the outer cylinder 7231, the first spring 7234 is fixedly connected to the sealing bead 7233 and the bottom hole plate 7235, and the sealing bead 7233 is in contact with the top hole wall 7232.

[0040] Due to the negative pressure in the heat exchange inner tube 722, the refrigerant between the heat exchange outer tube 721 and the heat exchange inner tube 722 pushes the sealing bead 7233 to move toward the bottom hole plate 7235 under the action of the negative pressure, and the refrigerant in the heat exchange outer tube 721 flows into the heat exchange inner tube 722 through the gap between the top hole wall 7232 and the sealing bead 7233. When the pump 76 stops working, there is no negative pressure in the heat exchange inner tube 722. The sealing bead 7233 contacts the top hole wall 7232 again under the action of the first spring 7234 recovering its deformation, so that the heat exchange outer tube 721 and the heat exchange inner tube 722 are sealed and isolated.

[0041] like Figure 7 As shown, the flow mechanism 724 includes a first annular shell 7241, an I-ring frame 7242, a second spring 7243 and a connecting plate 7444. The first annular shell 7241 is fixedly connected to the annular groove 7222, the I-ring frame 7242 is slidingly connected to the first annular shell 7241, the first annular shell 7241 is provided with an outer annular opening 72411, the outer annular opening 72411 is provided on the first annular shell 7241 away from the first through hole 7221, the I-ring frame 7242 is close to the first through hole 7221 and is surrounded by the first annular shell 7241 to form an air cavity 72412, the second spring 7243 is fixedly connected to the first annular shell 7241 and the I-ring frame 7242, the connecting plate 7444 is fixedly connected to the I-ring frame 7242, the connecting plate 7444 is provided with an inner tooth groove 74441, and the tooth pair of the inner tooth groove 74441 is linearly uniformly distributed along the axis of the connecting plate 7444.

[0042] The refrigerant enters the heat exchange inner tube 722 through the one-way mechanism 723. Under the action of negative pressure, the refrigerant flows to the annular groove 7222. When the refrigerant passes through the first annular shell 7241, the temperature rises to a different extent according to the amount of heat absorbed by the refrigerant. The temperature-sensitive gas in the air cavity 72412 between the I-ring frame 7242 and the first annular shell 7241 expands to a different extent due to heat. The I-ring frame 7242 slides along the first annular shell 7241, pushing the tooth surface of the inner tooth groove 74441 on the connecting plate 7444 to engage the transmission gear 7446.

[0043] like Figure 7 、 Figure 8As shown, the flow mechanism 724 also includes a second annular shell 7445, a transmission gear 7446, a first tooth surface plate 7447, a gear ring 7448 and a blade mechanism 7249. The second annular shell 7445 is fixedly connected to the heat exchange inner tube 722 and is arranged on the second annular shell 7445 near the center of the circle. The transmission gear 7446 is engaged with the tooth surface of the inner tooth groove 74441. The first tooth surface plate 7447 is fixedly connected to the transmission gear 7446. The second annular shell 7445 is provided with a second through hole 74451 and an inner ring rail 74452. The first tooth surface plate 7447 is rotatably connected to the inner ring rail 74452, the gear ring 7448 is rotatably connected to the second ring shell 7445, the gear ring 7448 is provided with inner ring teeth 74481 and outer ring teeth 74482, the first tooth surface plate 7447 is engaged with the tooth surface of the inner ring teeth 74481, the second through holes 74451 are provided with several groups, and the several groups of second through holes 74451 are evenly distributed along the circumference of the outer edge of the second ring shell 7445, the paddle mechanism 7249 is rotatably connected to the second through holes 74451, and the paddle mechanism 7249 is engaged with the tooth surface of the outer ring teeth 74482.

[0044] The tooth surface of the inner tooth groove 74441 on the connecting plate 7444 meshes with the transmission gear 7446. When the connecting plate 7444 moves horizontally away from the first ring shell 7241, the transmission gear 7446 is driven to rotate. The transmission gear 7446 is fixed to the first tooth surface plate 7447 and meshes with the tooth surface of the inner ring teeth 74481 on the gear ring 7448 through the first tooth surface plate 7447. The transmission gear 7446 transmits torque to the gear ring 7448. The gear ring 7448 rotates around the center of the second ring shell 7445 and transmits torque to the vane mechanism 7249. In the initial state, several groups of vanes The cross section of the mechanism 7249 and the second ring shell 7445 is arranged horizontally. As the temperature-sensitive gas in the air cavity 72412 expands due to heat, it pushes the connecting plate 7444, and transmits torque to the blade mechanism 7249 through the transmission gear 7446 and the gear ring 7448. The gap between several groups of blade mechanisms 7249 and the heat exchange outer tube 721 increases, and the flow rate of refrigerant flowing back from the main outer tube 73 to each heat exchange outer tube 721 increases. The heat exchange and heat dissipation capacity of this heat exchange outer tube 721 for the overheating area corresponding to the lamp group 6 is enhanced, thereby achieving the function of allocating refrigerant areas to regulate the heat dissipation effect.

[0045] like Figure 7 、 Figure 8 As shown, the blade mechanism 7249 includes a second tooth surface disk 72491, a connecting column 72492 and a fan blade 72493. The connecting column 72492 is fixedly connected to the second tooth surface disk 72491 and the fan blade 72493. The connecting column 72492 is rotatably connected to the second through hole 74451. The second tooth surface disk 72491 is engaged with the tooth surface of the outer ring tooth 74482.

[0046] The second tooth surface disk 72491 is meshed with the tooth surface of the outer ring tooth 74482 on the gear ring 7448, and the torque is transmitted to the second tooth surface disk 72491 through the rotation of the gear ring 7448. The connecting column 72492 drives the fan blades 72493 to rotate around the axis of the second through hole 74451. The gap between the fan blades 72493 and the heat exchange outer tube 721 increases, and the flow rate of refrigerant flowing back from the main outer tube 73 to each heat exchange outer tube 721 increases.

[0047] like Figure 9 As shown, the air cooling mechanism 74 includes a driving fan 741, an outer curved pipe 742, an inner curved pipe 743 and a one-way ball valve 744. The driving fan 741 and the outer curved pipe 742 are fixedly connected to the mounting frame 71. The outer curved pipe 742 is connected to the main outer pipe 73 through a pipe. The inner curved pipe 743 is connected to the main inner pipe 75 through a pipe. The one-way ball valve 744 is fixedly connected to the inner curved pipe 743. The one-way ball valve 744 is located on the end of the inner curved pipe 743 away from the main inner pipe 75. The pump 76 is connected to the end of the inner curved pipe 743 away from the main inner pipe 75 through a pipe.

[0048] After absorbing the heat of the lamp group 6, the refrigerant enters the main inner tube 75 from the heat exchange inner tube 722 and passes into the inner curved tube 743. Under the action of the negative pressure provided by the pump 76, the refrigerant flows into the outer curved tube 742 through the one-way ball valve 744 at the end of the inner curved tube 743 away from the main inner tube 75, driving the fan 741 to simultaneously perform air cooling on the refrigerant in the outer curved tube 742 and the inner curved tube 743, so that heat exchange occurs between the refrigerant and the air. After the outer curved tube 742, it flows back to each heat exchange outer tube 721 through the main outer tube 73 and the flow mechanism 724, completing a working process and continuing to quickly dissipate heat for the lamp group 6 and the photovoltaic panel 5.

[0049] Working principle of the present invention: The street lamp is powered by photovoltaic panels 5 for the street lamp and heat dissipation mechanism 7. The heat exchange tube 72 can quickly cool the lamp group 6 horizontally divided by the grille 3. The refrigerant in the heat exchange outer tube 721 absorbs heat, and the pump 76 generates negative pressure in the heat exchange inner tube 722. The refrigerant enters the heat exchange inner tube 722 through the one-way mechanism 723 under negative pressure and flows to the annular groove 7222. According to the amount of heat absorbed by the refrigerant, the temperature-sensitive gas in the air cavity 72412 expands to different degrees due to heat. , the I-shaped ring frame 7242 slides along the first ring shell 7241, pushing the tooth surface of the inner tooth groove 74441 on the connecting plate 7444 to mesh with the transmission gear 7446, and the transmission gear 7446 rotates, and the torque is transmitted to the gear ring 7448 through the first tooth surface plate 7447 and the tooth surface of the inner ring gear 74481. The gear ring 7448 rotates around the center of the second ring shell 7445. In the initial state, several groups of fan blades 72493 are arranged horizontally with the cross section of the second ring shell 7445. As the air cavity 72412 The temperature-sensitive gas expands due to heat, and the second tooth surface disk 72491 meshes with the tooth surface of the outer ring tooth 74482, driving the fan blade 72493 to rotate around the axis of the second through hole 74451. The gap between several groups of fan blades 72493 and the heat exchange outer tube 721 increases, and the flow of refrigerant returning from the main outer tube 73 to the corresponding heat exchange outer tube 721 increases. The heat exchange and heat dissipation capacity of this heat exchange outer tube 721 for the overheating area corresponding to the lamp group 6 is enhanced, achieving the function of allocating refrigerant areas to control the heat dissipation effect, and the corresponding lamps The overheated area of ​​group 6 increases the heat dissipation efficiency of the corresponding position. The refrigerant that has absorbed the heat of lamp group 6 enters the main inner tube 75 from the heat exchange inner tube 722 and passes into the inner curved tube 743. Under the negative pressure provided by the pump 76, the refrigerant flows into the outer curved tube 742 through the one-way ball valve 744, driving the fan 741 to cool the refrigerant with air, and then flows back to each heat exchange outer tube 721 through the main outer tube 73 and the flow mechanism 724, completing a working process and continuing to quickly dissipate heat for the lamp group 6 and the photovoltaic panel 5.
