[0012] By adopting the above technical solution, a temperature switch is fixed in the water tank, which can detect the temperature of the cooling water in the water tank.

[0013] Optionally, the cooling water pipe is arranged in a serpentine shape on one side of the first installation area.

[0014] By adopting the above technical solution, the cooling water pipe is arranged in a serpentine shape on one side of the first installation area, which increases the contact between the cooling water pipe and the installation plate and improves the cooling effect of the cooling water pipe on the installation plate.

At the same time, the exhaust holes on the baffle can allow hot air to flow out without affecting the refrigeration of the refrigerator.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. When the weather is hot, turn on the refrigerator, which will cool the water in the water tank.

DETAILED DESCRIPTION

[0034] The following is combined with Figure 1-4 This application is described in further detail.

[0035] The present application embodiment discloses a street lamp heat dissipation structure. Figure 1-Figure 3A street lamp heat dissipation structure includes a mounting plate 1 and a heat sink 2 fixedly mounted in a lampshade 100. The lampshade 100 includes a first mounting area 101 and a second mounting area 102. The mounting plate 1 is fixedly mounted in the middle position of the side wall of the first mounting area 101. A lamp board 103 for lighting is fixed to the bottom surface of the mounting plate 1 by bolts. A transparent protective plate 107 is fixed to the lampshade 100 under the lamp board 103 by bolts. The protective plate 107 can block external debris, thereby protecting the lamp board 103; at the same time, the transparent shape of the protective plate 107 will not affect the normal use of the lamp board 103. A plurality of heat sinks 2 are provided. The multi-plate heat sinks 2 are fixed on the top surface of the mounting plate 1 at equal intervals to achieve preliminary heat dissipation of the mounting plate 1 and the lamp board 103.

[0036] Reference Figure 1 , Figure 3 as well as Figure 4 A street lamp heat dissipation structure also includes a secondary heat dissipation component 3. Two groups of secondary heat dissipation components 3 are provided, and the two groups of secondary heat dissipation components 3 are symmetrically arranged on both sides of the second installation area 102 of the lampshade 100. The secondary heat dissipation component 3 includes a water tank 31, a refrigerator 32 connected to the water tank 31, and a cooling water pipe 33 connected to the water tank 31. A convex plate 311 is integrally formed on the outer bottom wall of the water tank 31. First fixing bolts 312 are penetrated on opposite sides of the outer side edge of the convex plate 311. The convex plate 311 and the inner wall of the lampshade 100 are fixed by the first fixing bolts 312, so that during the movement of the installed lampshade 100, the water tank 31 will not move relative to the lampshade 100, and thus the refrigerator 32 and the cooling water pipe 33 connected to the water tank 31 will not be pulled.

[0037] Reference Figure 1 , Figure 3 as well as Figure 4 , the refrigerator 32 is fixedly mounted on the side wall adjacent to the water tank 31 in the second mounting area 102 by bolts. The hot end of the refrigerator 32 extends out of the lampshade 100, and a hot air discharge baffle 321 is fixed to the outer end surface of the hot end of the refrigerator 32. The baffle 321 can prevent foreign debris from entering the refrigerator 32, thereby better protecting the parts in the refrigerator 32. Both ends of the cooling water pipe 33 are fixed to the adjacent side walls of the water tank 31. The cooling water pipe 33 can pass through the inner wall of the lampshade 100 to enter the first mounting area 101, and the cooling water pipe 33 in the first mounting area 101 is located on the upper surface of the mounting plate 1. The cooling water pipe 33 located in the first mounting area 101 is arranged in a serpentine shape, and the cooling water pipe 33 located in the first mounting area 101 is staggered with the heat sink 2. When the weather is hot, turn on the refrigerator 32, and the refrigerator 32 cools the water in the water tank 31. The cooling water cools the mounting plate 1 and the lamp board 103 through the cooling water pipe 33, which speeds up the heat dissipation of the lamp board 103, thereby increasing the service life of the lamp board 103.

[0038] Reference Figure 1 , Figure 3as well as Figure 4 A temperature switch is fixed in the water tank 31. The temperature switch is electrically connected to the refrigerator 32. When the water temperature in the water tank 31 is too high, the temperature switch controls the circuit connected to the refrigerator 32 to start the refrigerator 32, thereby cooling the water in the water tank 31, so that the secondary heat dissipation component 3 can better achieve the heat dissipation function. A micro water pump is also fixed in the water tank 31. The water inlet end of the micro water pump is located in the water tank 31. The water outlet end of the micro water pump is located in the cooling water pipe 33. The water in the cooling water pipe 33 and the water tank 31 can flow, so that the water cooled by the refrigerator 32 can enter the cooling water pipe 33, thereby improving the heat dissipation effect of the secondary heat dissipation component 3 on the mounting plate 1 and the lamp board 103.

[0039] Reference Figure 1 , Figure 2 as well as Figure 4 , a partition 104 is fixedly installed in the second installation area 102. A line control for the useful refrigerator 32 and the micro water pump line is provided on the top of the partition 104. Two partitions 104 are provided, and the two partitions 104 separate the water tank 31 from the line for supplying power to the lamp board 103. The water in the water tank 31 is prevented from flowing into the line for supplying power to the lamp board 103 as much as possible, thereby increasing the safety of the secondary heat dissipation component 3. The lampshade 100 is provided with an opening on the bottom surface of the second installation area 102, and a sealing plate 105 is inserted into the lampshade 100 at the opening. Three second fixing bolts 106 are penetrated on the outer edge of the bottom surface of the sealing plate 105. The sealing plate 105 is fixed to the lampshade 100 by the second fixing bolts 106. The sealing plate 105 can be removed by disassembling the second fixing bolts 106, which is convenient for the maintenance or replacement of the water tank 31 and the refrigerator 32. At the same time, installing the sealing plate 105 can protect the water tank 31 and the refrigerator 32 from external damage.

[0040] The implementation principle of a street lamp heat dissipation structure of an embodiment of the present application is as follows: when the weather is hot, the temperature inside the lampshade 100 rises, and at this time, the heat dissipation effect of the heat sink 2 on the mounting plate 1 and the lamp board 103 is not good. At this time, the cooling water pipe 33 can absorb the heat generated by the lamp board 103. The heat dissipation effect of the lamp board 103 is improved. At the same time, when the temperature of the cooling water in the cooling water pipe 33 rises, due to the setting of the micro water pump, the cooling water with the increased temperature in the cooling water pipe 33 can flow into the water tank 31. After the cooling water with the increased temperature flows into the water tank 31, the temperature switch drives the circuit where the refrigerator 32 is located to be connected, so that the refrigerator 32 is started, and the temperature of the cooling water in the water tank 31 is reduced, which is convenient for the secondary heat dissipation component 3 to absorb the heat of the mounting plate 1 and the lamp board 103 for a long time, thereby improving the heat dissipation effect of the secondary heat dissipation component 3.

[0041] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
