[0032] Example 1

[0033] The embodiment of the present invention provides a heat dissipation device for a lamp, such as Figures 1-9 As shown, it includes: a lamp housing 1, a battery box body 2 is set at one end of the lamp housing 1, a battery 3 is set in the battery box body 2, heat sinks 4 are set on both sides of the battery 3, one end of the heat sink 4 extends to the outside of the battery box body 2, the heat sink 4 divides the battery box body 2 into an air intake chamber and a heat dissipation chamber, the battery 3 is located in the heat dissipation chamber, heat dissipation holes are set in the heat sink 4, a cooling fan 5 is set in the heat dissipation holes, an air outlet is set at the center of the bottom of the battery box body 2, two air inlet holes are symmetrically set at the bottom of the battery box body 2, the air inlet hole is located on the side of the heat sink 4 away from the air outlet, a controller and a temperature sensor are set in the battery box body 2, the temperature sensor is used to detect the real-time temperature in the heat dissipation chamber, and the controller is electrically connected to the cooling fan 5, the temperature sensor and the battery 3 respectively.

[0034] The working principle and beneficial effects of the above technical solution are as follows: the temperature sensor is arranged in the heat dissipation cavity to detect the real-time temperature in the heat dissipation cavity, thereby determining the temperature of the environment in which the battery 3 is located; when the real-time temperature in the heat dissipation cavity detected by the temperature sensor is lower than the preset temperature (the preset temperature is set by the user), the heat dissipation fan 5 does not start, and the gas can be discharged through the air outlet to achieve heat dissipation, thereby achieving energy saving; when the real-time temperature in the heat dissipation cavity detected by the temperature sensor reaches the preset temperature, the controller can control the heat dissipation fan 5 to start automatically, and the air is accelerated to flow into the air inlet cavity through the air inlet, and then flows to the heat dissipation cavity through the heat dissipation holes. As the air With the continuous inflow of air, the air flows along the outer wall of the battery 3 body, thereby taking away the heat in the heat dissipation cavity, and finally flows out from the air outlet to the outside of the battery box body 2, thereby achieving efficient heat dissipation of the battery 3. At the same time, the heat sink 4 can absorb the heat in the battery box body 2 and dissipate the heat to the external environment by extending to one end outside the battery box body 2, thereby further improving the heat dissipation effect. Through the above scheme, rapid heat dissipation of the battery 3 is achieved, the operating temperature of the battery 3 can be reduced, thereby extending its service life, reducing maintenance costs, and improving the performance and stability of the battery 3, ensuring that the battery 3 of the lamp can work normally in a high temperature environment.

[0035] Example 2

[0036] On the basis of the above embodiment 1, Figure 5 、 Figure 8 As shown, a support frame 6 is set in the battery box body 2, and the battery 3 is set on the support frame 6. A vent is set at the bottom of the support frame 6. The four corners of the bottom of the support frame 6 are connected to the bottom wall of the battery box body 2 through support columns. There is a gap between the outer wall of the battery 3 and the inner wall of the battery box body 2.

[0037] The working principle and beneficial effects of the above technical solution are as follows: the battery 3 is installed on the support frame 6, the bottom of the support frame 6 is connected to the bottom wall of the battery box body 2 through a support column, and a vent is provided at the bottom of the support frame 6, thereby ensuring that there are gaps between the six sides of the outer wall of the battery 3 and the inner wall of the battery box body 2, ensuring that air can flow along the outer wall of the battery 3, taking away the heat generated by the battery 3, thereby reducing the temperature of the battery 3.

[0038] Example 3

[0039] On the basis of Example 2, Figure 2 As shown, an air inlet filter 7 is provided in the air inlet, and an air outlet filter 8 is provided in the air outlet.

[0040] The working principle and beneficial effects of the above technical solution are as follows: the air inlet filter 7 can block impurities in the air passing through the air inlet hole, and the air outlet filter 8 can block external impurities from entering the battery box body 2 through the air outlet hole, thereby preventing impurities from entering the battery box body 2 and damaging the internal components of the battery box body 2.

[0041] Example 4

[0042] On the basis of Example 3, Figure 5-Figure 9 As shown, an air intake cylinder 9 is arranged above the battery 3, and the upper end of the air intake cylinder 9 is connected to the inner wall of the upper end of the battery box body 2. Air intake pipes 10 are arranged on both sides of the air intake cylinder 9. The two air intake pipes 10 are centrally symmetrically distributed about the center of the air intake cylinder 9. One end of the air intake pipe 10 is connected to the inside of the air intake cylinder 9, and the other end of the air intake pipe 10 is connected to the heat sink 4 and connected to the heat dissipation hole.

[0043] The working principle and beneficial effects of the above technical scheme are as follows: the lower end of the air intake cylinder 9 is arranged at the center of the horizontal plate and is connected to the center of the horizontal plate. The horizontal plate is horizontally arranged in the heat dissipation cavity. The horizontal plate can isolate the air and prevent the air from flowing to the top of the battery box body 2, thereby ensuring the heat dissipation effect. The air in the air intake cavity is accelerated to flow into the air intake pipe 10 through the heat dissipation holes under the action of the heat dissipation fan 5. Then the air in the air intake pipes 10 on both sides is gathered in the air intake cylinder 9 and blown from the lower end of the air intake cylinder 9 to the upper surface of the battery 3. Then the gathered air flows along the upper surface of the battery 3 together, and then passes through the side wall of the battery 3, reaches the bottom wall of the battery box body 2 and flows along the bottom wall of the battery 3, and finally flows out after passing through the air outlet filter 8. Through the above scheme, it can be ensured that the air flows evenly over the surface of the battery 3, and the chaotic flow of air in the heat dissipation cavity is avoided, which causes local overheating of the battery 3, further improves the heat dissipation effect of the battery 3, and extends the service life of the battery 3.

[0044] Example 5

[0045] On the basis of Example 4, Figure 5-Figure 7 As shown, a rotating shaft 11 is set in the air intake cylinder 9, and the upper end of the rotating shaft 11 is rotatably connected to the inner wall of the upper end of the battery box body 2. A plurality of partitions 12 are set on the outer wall of the rotating shaft 11, and the plurality of partitions 12 are distributed in a circular array about the center line of the rotating shaft 11.

[0046] The working principle and beneficial effects of the above technical solution are as follows: when the air in the two intake pipes 10 enters the intake cylinder 9 at the same time, the two air streams will collide with each other and cause energy loss. In order to avoid direct collision of the two air streams, a rotating shaft 11 is provided in the intake cylinder 9, and a partition 12 is provided outside the rotating shaft 11. When the air flows into the intake cylinder 9 through the intake pipe 10, the air first contacts the partition 12 and flows downward along the partition 12 and blows toward the center position of the upper surface of the battery 3, avoiding direct collision of the two air streams, preventing the air flow rate from being greatly reduced, ensuring the heat dissipation efficiency, and ensuring that the heat dissipation device can operate efficiently and stably.

[0047] Example 6

[0048] On the basis of Example 5, Figure 7 、 Figure 9As shown, the lower end of the rotating shaft 11 extends to the outside of the air intake cylinder 9 and a diffusion disk 13 is provided. The diffusion disk 13 is in the shape of a cone. The diameter of the upper end of the diffusion disk 13 is smaller than the diameter of the lower end of the diffusion disk 13. A plurality of guide plates 14 are provided on the upper surface of the diffusion disk 13. The guide plates 14 are arranged radially along the diffusion disk 13, and the plurality of guide plates 14 are distributed in a circular array about the center line of the diffusion disk 13.

[0049] The working principle and beneficial effects of the above technical solution are as follows: the air entering the air intake cylinder 9 flows along the partition 12 to the diffusion disk 13, and flows along the upper surface of the diffusion disk 13. Under the guidance of the guide plate 14, the air can be diffused in different directions, so that the air can be evenly distributed on the surface of the battery 3, optimizing the air flow path and improving the heat dissipation efficiency. At the same time, when the air blows towards the partition 12, it can push the partition 12 to move, thereby driving the rotating shaft 11 to rotate, the rotation of the rotating shaft 11 drives the diffusion disk 13 to rotate, and the rotation of the diffusion disk 13 drives the guide plate 14 to rotate, realizing the diffusion of the air, which is conducive to the uniform distribution of the air in the heat dissipation cavity, and enhancing the speed of the air flowing along the surface of the battery 3, further improving the heat dissipation efficiency of the heat dissipation device. When the air intake filter 7 on one side is blocked, the air flowing into the air intake cavity on this side will be reduced. Since the partition 12 is slidingly connected to the inner wall of the air intake cylinder 9, the rapid rotation of the partition 12 can play a role of suction, thereby increasing the air flow rate in the air intake cavity on the side where the air intake filter 7 is blocked, avoiding a significant reduction in heat dissipation efficiency.

[0050] Example 7

[0051] On the basis of Example 6, Figure 9 As shown, a plurality of blowing groups are arranged in the diffusion disk 13, and the plurality of blowing groups are distributed in a circular array about the center line of the diffusion disk 13. A single blowing group is located between two adjacent guide plates 14. The blowing group includes a plurality of blowing holes 15, and the plurality of blowing holes 15 are evenly spaced along the radial direction of the diffusion disk 13. The upper and lower ends of the blowing holes 15 pass through the upper and lower sides of the diffusion disk 13. A plurality of toggle bars 16 are provided on the lower surface of the diffusion disk 13, and the toggle bar 16 is located between two adjacent blowing groups.

[0052] The working principle and beneficial effects of the above technical solution are as follows: part of the air can be blown to the center position of the upper surface of the battery 3 through the blowing hole 15, avoiding the inability to dissipate heat to the upper surface of the battery 3 due to obstruction by the diffusion disk 13, improving the uniformity of heat dissipation, and avoiding local overheating that causes performance degradation or damage to the battery 3. A plurality of toggle bars 16 are provided on the lower surface of the diffusion disk 13, and the toggle bars 16 correspond one-to-one to the guide plates 14. The toggle bars 16 can toggle the air between the diffusion disk 13 and the upper surface of the battery 3, so that the air flows along the upper surface of the battery 3, and at the same time increases the air flow area below the diffusion disk 13, which helps to evenly distribute the air and prevent local overheating of the upper surface of the battery 3.

[0053] Example 8

[0054] On the basis of any one of Examples 3-7, Figure 5 、 Figure 8 As shown, a baffle block 20 is provided on one side wall of the heat sink 4 away from the battery 3, one end of the baffle block 20 is connected to the heat sink 4, and an inlet air flow channel is formed between the other end of the baffle block 20 and the inner wall of the battery box body 2. The longitudinal cross-section of the baffle block 20 is an isosceles trapezoidal shape, and the area of ​​the end of the baffle block 20 close to the heat sink 4 is larger than the area of ​​the end of the baffle block 20 away from the heat sink 4. A first inclined surface is provided on the upper side of the baffle block 20, and a second inclined surface is provided on the lower side of the baffle block 20.

[0055] The working principle and beneficial effects of the above technical solution are as follows: after the air enters the air intake cavity, under the action of the baffle block 20, the air can flow along the air intake duct, and the cross-sectional area of ​​the air intake duct is smaller than the cross-sectional area of ​​the air intake hole, thereby increasing the air flow speed and improving the heat dissipation efficiency.

[0056] Example 9

[0057] On the basis of Example 8, Figure 8 As shown, a liquid inlet hole 21 is provided on the upper surface of the battery box body 2, the lower end of the liquid inlet hole 21 is communicated with the interior of the air inlet cavity, a liquid inlet filter 22 is provided in the liquid inlet hole 21, and a first blocking plate 23 is provided below the liquid inlet hole 21. The first blocking plate 23 is hingedly connected to the inner wall of the upper end of the battery box body 2 near one end of the heat sink 4, a first moisture absorbing block 24 is provided between the first blocking plate 23 and the baffle block 20, and the lower end of the first moisture absorbing block 24 is connected to the first inclined surface, a liquid outlet hole 25 is provided on the bottom wall of the battery box body 2, the upper end of the liquid outlet hole 25 is communicated with the interior of the air inlet cavity, the liquid outlet hole 25 is located between the heat sink 4 and the air inlet hole, and a second blocking plate 26 is provided below the liquid outlet hole 25. The second blocking plate 26 One end away from the heat sink 4 is hingedly connected to the bottom wall of the battery box body 2, and the upper surface of the second blocking plate 26 is connected to the side wall of the heat sink 4 through a connecting spring 27. A sliding hole is provided in the baffle block 20, and a sliding column 28 is slidingly provided in the sliding hole. A first roller 29 is provided at the upper end of the sliding column 28, and the first roller 29 contacts the lower surface of the first blocking plate 23. A return spring 30 is sleeved on the outside of the sliding column 28, and one end of the return spring 30 is connected to the baffle block 20, and the other end of the return spring 30 is connected to the outer wall of the sliding column 28. The lower end of the sliding column 28 extends to the top of the second blocking plate 26 and is provided with a second roller 31, and the second roller 31 contacts the upper surface of the second blocking plate 26.

[0058] The working principle and beneficial effects of the above technical solution are as follows: when it rains outside, part of the rainwater will flow through the liquid inlet filter 22 and then flow into the liquid inlet hole 21. If the blockage degree of the air inlet filter 7 is less than the preset blockage degree, the impact force of the air and the elastic force of the return spring 30 can keep the first blocking plate 23 in a horizontal state. When the blockage degree of the air inlet filter 7 reaches the preset blockage degree, the air entering the air inlet cavity is reduced. At this time, the impact force of the air on the first blocking plate 23 is reduced. Under the action of gravity, the first blocking plate 23 rotates downward and is aligned with the side wall of the baffle block 20. The contact between the first and second sealing plates 23 and the second sealing plate 26 is caused to move downwards, so that the rainwater stored in the liquid inlet hole 21 flows downwards along the first blocking plate 23 and flows to the air inlet filter 7. The rainwater can wash the air inlet filter 7 and remove impurities attached to the surface of the air inlet filter 7. At the same time, the first blocking plate 23 drives the first roller 29 to move downwards, and the first roller 29 drives the sliding column 28 to slide downwards. The return spring 30 is compressed, and the sliding column 28 drives the second blocking plate 26 to rotate with the hinge position as the center of the circle through the second roller 31. The connecting spring 27 is stretched, so that the liquid outlet 25 is connected to the external environment, and part of the rainwater can pass through the liquid outlet 25. The rainwater flows out through the liquid outlet 25, and the rainwater flowing out of the liquid outlet 25 can wash the inside of the air intake filter 7, thereby improving the cleaning effect. At the same time, when the rainwater flows out of the liquid outlet 25, the rainwater can contact the heat sink 4 under the guidance of the second blocking plate 26, thereby taking away the heat inside the heat sink 4, further improving the heat dissipation efficiency. The first blocking plate 23 contacts the side wall of the baffle block 20 to ensure that the first blocking plate 23 is in an inclined state and seals the heat dissipation hole to prevent rainwater from flowing into the heat dissipation cavity. When the air intake filter 7 is cleaned, the reset spring 30 and the air Under the action of the impact force, the first blocking plate 23 returns to its original position and remains in a horizontal state. Under the action of the connecting spring 27, the second blocking plate 26 returns to its original position, and the air quickly flows into the air intake cavity through the air intake filter 7, ensuring the heat dissipation efficiency. Through the above scheme, the air intake filter 7 can be automatically cleaned, reducing the labor intensity of the staff, while ensuring the air intake effect, improving the heat dissipation efficiency of the heat dissipation device, and realizing efficient heat dissipation of the battery 3, thereby extending its service life, improving the performance and stability of the battery 3, and reducing maintenance costs.

[0059] Example 10

[0060] On the basis of Example 9, Figure 8 As shown, an air flow channel 32 is set in the baffle block 20, and the air flow channel 32 runs through the upper and lower sides of the baffle block 20. A second moisture absorbing block 33 is set at the lower end of the air flow channel 32, and the upper surface of the second moisture absorbing block 33 is connected to the second inclined surface. An extrusion plate 34 is set outside the sliding column 28, and the upper surface of the extrusion plate 34 is in contact with the lower surface of the second moisture absorbing block 33.

[0061] The working principle and beneficial effects of the above technical solution are as follows: the first moisture absorbing block 24 and the second moisture absorbing block 33 can both be made of absorbent sponge material. When the first sealing plate 23 contacts the baffle block 20, the squeezing plate 34 separates from the second moisture absorbing block 33, and the air in the air intake cavity flows into the heat dissipation cavity through the air flow channel 32, ensuring the heat dissipation effect on the battery 3. The second moisture absorbing block 33 can absorb moisture in the air and ensure the dryness of the air. When the first sealing plate 23 returns to its original position, the squeezing plate 34 contacts and squeezes the second moisture absorbing block 33, and the moisture in the second moisture absorbing block 33 is squeezed out, which facilitates the next use of the second moisture absorbing block 33.

[0062] The present application also provides a heat dissipation method for a lamp, which uses the heat dissipation device of the above-mentioned lamp to dissipate heat from the lamp, including: when the real-time temperature in the heat dissipation cavity detected by the temperature sensor reaches a preset temperature, the controller controls the heat dissipation fan 5 to automatically turn on, and the external air enters the air inlet cavity through the air inlet hole, and flows into the heat dissipation cavity through the heat dissipation hole. When the external air flows through the battery 3, it takes away the heat of the battery 3, and finally flows out of the battery box body 2 through the air outlet hole, thereby realizing heat dissipation of the battery 3.
