Description

TECHNICAL FIELD

[0001] The application relates to the technical field of solar lamps, in particular to a solar lamp facilitating heat dissipation. BACKGROUND

[0002] A solar lamp is a lamp powered by solar energy. The solar energy is absorbed by a solar panel, stored and converted into electric energy to provide power for the lamp. The existing solar lamp, as a typical energy-saving lighting device, has excellent safety, environmental protection and energy-saving performance, and is therefore widely promoted. In particular, the solar lamp is used for lighting as a street lamp. However, the existing energy-saving solar lighting street lamp only cools the LED module and the power module by passive heat dissipation during use, which results in poor overall cooling effect of the street lamp, and thus the temperature continuously accumulates at the LED module and the power module during use of the lamp, affecting the normal use of the LED module and the power module.

[0003] For example, the solar lamp facilitating heat dissipation disclosed in the Chinese utility model patent (application number: CN202323444776.6) has the following description in the specification: the solar lamp is an electric lamp converted into electric energy by a solar cell panel. During the day, even on cloudy days, the solar power generator (solar panel) can collect and store solar energy. The solar lamp, as a safe and environmentally friendly new electric lamp, is increasingly valued. The electronic components inside the existing lampshade will generate heat during long-term use. If the heat is not discharged to the outside of the lampshade in time, the service life of the electronic components inside the lampshade may be reduced or damaged. The Chinese patent with the publication number CN218544198U is proposed in the prior art to solve the above technical problems. The technical solution disclosed in the patent document is as follows: a solar lamp facilitating heat dissipation, comprising a lamp disposed on an inclined support rod, a solar panel disposed on one side of the support rod, the lamp comprising an upper housing, a cover body disposed below the front end of the housing, an electric component on the side wall of the end of the housing connected to a fan component through an L-shaped drive shaft, one end of the fixed rod of the fan component connected in the card slot at the far end of the drive shaft through a spherical clamping protrusion, and the other end connected with the fan; a fixed sleeve is arranged on one end of the fixed rod close to the fan, a spherical connecting part on one side of the fixed sleeve is connected with a bearing rod on the housing, and the bearing rod is perpendicular to the fixed rod. The above-mentioned solar lamp facilitating heat dissipation has the advantages of simple structure, rapid heat dissipation, and improved service life of the lamp. However, the heat dissipation degree of the heat dissipation component cannot be adjusted, which cannot adapt to different solar lamps and has certain limitations.

[0004] Therefore, we improve it and propose a solar lamp facilitating heat dissipation. SUMMARY

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] This invention provides a technical solution: such as Figures 1-10 The invention relates to a solar lamp that facilitates heat dissipation. It includes a lamp post 1, a solar panel 6 mounted on the top of the lamp post 1, a lamp cover 3 mounted via an extension rod 2 on the side of the lamp post 1, and an equipment box 5 mounted on the other side of the lamp post 1. An LED module 7 for lighting is provided at the bottom of the inner cavity of the lamp cover 3. A passive heat dissipation component that achieves cooling through heat conduction is provided on the top of the LED module 7. An active heat dissipation component that achieves cooling through a fan is provided inside the equipment box 5.

[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 5As shown, the passive heat dissipation component includes a heat spreader 8 fixedly installed on the upper surface of the LED module 7. The heat spreader 8 facilitates the uniform distribution of temperature on the outer surface of the LED module 7. A plurality of connecting heat pipes 10 are uniformly arranged in an n-shape on the upper surface of the LED module 7. The plurality of connecting heat pipes 10 are connected by a main heat pipe 9. The connecting heat pipes 10 are used to conduct the heat generated by the LED module 7 to the interior of the main heat pipe 9.

[0036] A heat transfer pipe 11 is symmetrically installed on the top of the main heat pipe 9. A first thermal bridge 13 is fixedly installed on the top of the heat transfer pipe 11. A sleeve 12 extending to the top of the lamp cover 3 is sleeved on the upper middle part of the heat transfer pipe 11. A heat sink 16 is fixedly installed on the top of the sleeve 12.

When there is wind from the outside and it blows towards the fan blade 18, the fan blade 18 will first be blown and shaken by the torsion spring, and then it will hit the heat sink 16 to achieve self-cleaning of the heat sink 16. Then, as the wind force increases, it will drive the heat sink 16 to rotate.

[0039] like Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, the active heat dissipation assembly includes a second heat bridge 19 disposed in the inner cavity of the equipment box 5. A rotating heat pipe 4 is fixedly installed at one end of the second heat bridge 19. The rotating heat pipe 4 extends along the inner cavity of the extension rod 2 to the inner cavity of the lamp cover 3 and is fixedly connected to one end of the main heat pipe 9. The rotating heat pipe 4 is used to transport excess heat inside the main heat pipe 9 to the inside of the second heat bridge 19.

[0040] The outer side of the second heat bridge 19 is fitted with heat dissipation fins 20. A brushless fan 21 is fixedly installed at the end of the heat dissipation fins 20 away from the second heat bridge 19. The brushless fan 21 facilitates heat dissipation for the second heat bridge 19 and the heat dissipation fins 20. On the side of the equipment box 5 with the same air outlet direction as the brushless fan 21, heat dissipation holes 37 are evenly distributed. The heat dissipation holes 37 are labyrinth-shaped holes to prevent dust and rainwater from penetrating into the interior of the equipment box 5.

[0041] The brushless fan 21 is fixedly installed at one end of the air outlet, the output shaft 22 is fixedly installed at the other end of the output shaft 22, the reduction box 23 is arranged on the outer side of the output end of the reduction box 23, and the brushless fan 21 can drive the plurality of mounting rods 24 to rotate through the cooperation of the output shaft 22 and the reduction box 23 when the brushless fan 21 works, the extrusion wheel 25 is sleeved at the other end of the mounting rod 24, the guide plates 26 are symmetrically arranged on the left and right sides of the reduction box 23, the guide grooves 27 are arranged on the inner sides of the guide plates 26, the guide flow pipes 28 are sleeved with the guide plates 26 through the guide grooves 27, and the other side of the guide flow pipe 28 is in contact with the extrusion wheel 25, the guide plates 26 are extrudedly connected with the extrusion wheel 25 through the guide grooves 27 arranged on the inner sides of the guide plates 26, and then the delivery of the guide flow pipe 28 is realized by using the peristaltic pump principle.

[0042] The third heat bridge 38 is symmetrically arranged on the two sides of the heat dissipation fin 20, the first liquid storage tank 29 and the second liquid storage tank 30 are respectively connected to the heat dissipation fin 20 through the third heat bridge 38, the third liquid storage tank 32 is arranged between the first liquid storage tank 29 and the second liquid storage tank 30, the third liquid storage tank 32 is located below the reduction box 23, and the upper surfaces of the third liquid storage tank 32 are penetrated through the side walls of the first liquid storage tank 29 and the second liquid storage tank 30 through two groups of guide flow pipes 28.

[0043] The partition plate 31 is fixedly installed at the bottom of the third liquid storage tank 32, the link pipes 33 are symmetrically arranged at the bottom of the third liquid storage tank 32 and penetrate the partition plate 31, the electromagnetic valves 34 are arranged on the outer sides of the link pipes 33, the fourth liquid storage tank 35 is connected to the bottom of the link pipe 33, the bottom of the fourth liquid storage tank 35 is in contact with the power module, the heat dissipation fans 36 are symmetrically arranged on one side of the fourth liquid storage tank 35, and the inner cavities of the first liquid storage tank 29, the second liquid storage tank 30, the third liquid storage tank 32 and the fourth liquid storage tank 35 are all filled with paraffin.

[0044] Working principle: when in use, first, the device is taken out and placed in a proper position, in the normal use process, the LED module 7 installed at the bottom of the inner cavity of the lampshade 3 continuously generates heat, at this time, the temperature on the upper surface of the LED module 7 is uniformly distributed by the uniform temperature plate 8 arranged on the upper surface of the LED module 7, so as to avoid local overheating and damage, then the heat is conducted to the main heat pipe 9 through the plurality of connecting heat pipes 10 arranged on the upper surface of the LED module 7.

[0045] Passive heat dissipation in the windless state: as the heat continuously accumulates in the main heat pipe 9, first, the two groups of conduction heat pipes 11 symmetrically arranged at the top of the main heat pipe 9 conduct the temperature to the heat dissipation fins 16 arranged at the top of the lampshade 3 through the first heat bridge 13 installed at the top of the conduction heat pipe 11, and the heat dissipation fins 16 interact with the external environment, so as to realize passive heat dissipation.

[0046] Passive heat dissipation in windy conditions: when the heat dissipation fins 16 are continuously dissipating heat, and the outside environment has flowing wind, first of all, the wind will push the fan blades 18 to rotate. Since the fan blades 18 are connected to the mounting shaft 17 through a torsional spring, when the fan blades 18 are blown by the wind, they will first sway and then continuously hit the heat dissipation fins 16 sleeved on their outer side. In this process, the self-cleaning of the heat dissipation fins 16 can be achieved through the method of generating vibration by impact. As the wind force continues to increase, the fan blades 18 begin to rotate, driving the heat dissipation fins 16 and the sleeve pipe 12 installed at the bottom to rotate, thereby increasing the degree of interaction between the heat dissipation fins 16 and the outside environment, and achieving better heat dissipation.

[0047] Thermal conduction active cooling: as the energy-saving solar lamp is continuously used, the heat inside the lampshade 3 continues to accumulate, and the heat dissipation fins 16 cannot completely dissipate heat. At this time, the excess heat will be conducted to the second heat bridge 19 in the inner cavity of the equipment box 5 through the rotating heat pipe 4, and the temperature will be conducted to the first and second liquid storage tanks 29 and 30 through the third heat bridges 38 symmetrically arranged at both ends, thereby melting the paraffin filled in the inner cavity, and achieving rapid cooling by melting the paraffin. Until the paraffin inside is completely melted, the brushless fan 21 is started, and wind cooling auxiliary heat dissipation is achieved. When the energy-saving solar street lamp is used in extremely low environment, the melted paraffin can also store heat, thereby keeping the equipment box 5 warm.

[0048] Wind cooling auxiliary heat dissipation: as the temperature inside the heat dissipation fins 20 continues to accumulate, and the paraffin is completely melted, and the brushless fan 21 is turned on, wind cooling is achieved by the brushless fan 21 cooperating with the heat dissipation fins 20. At the same time, the brushless fan 21 also drives the six groups of mounting rods 24 and the extrusion wheel 25 arranged in an array through the output shaft 22 and the speed reducer 23 installed on the outer side, and cooperates with the guide plate 26 and the guide groove 27 to realize the transportation of the fluid paraffin inside the flow guide pipe 28, and cooperates with the third liquid storage tank 32 to realize reciprocating circulation. When the melted paraffin is inside the flow guide pipe 28, the brushless fan 21 can also achieve cooling.

[0049] Power heat dissipation: when the energy-saving solar lamp is used, the power module installed at the bottom of the inner cavity of the equipment box 5 will also continuously dissipate heat, and as the temperature continues to rise, it will also dissipate heat through direct contact with the fourth liquid storage tank 35, and utilize the melted paraffin filled in the inner cavity of the fourth liquid storage tank 35 for heat conduction. At the same time, the symmetrical heat dissipation fan 36 installed on one side of the fourth liquid storage tank 35 needs to be turned on to realize synchronous heat dissipation.

[0050] Power protection in low temperature state: if the energy-saving solar lamp is used in low temperature environment, firstly, the power is not started, the LED module 7 is directly powered by the solar panel 6 to work normally and continuously generate heat, at this time, the above steps are repeated to dissipate heat, in the heat dissipation process, the electromagnetic valve 34 also needs to be opened, and the fourth liquid tank 35 is communicated with the third liquid tank 32 through the connecting pipe 33, so that the melted paraffin passes through the fourth liquid tank 35, and the fourth liquid tank 35 is in contact with the power supply to heat it, so that the use of the power supply in the low temperature environment can be avoided, and the power supply is damaged.
