[0043] A second pipe 23 is fixedly embedded on the top of the box 13, and a switch valve 24 is provided outside the second pipe 23. The heat dissipation copper pipe 15 is fixedly connected to the shell 1 and the box 13, and the pipe 17 is fixedly connected to the shell 1;

[0044] In this embodiment, the operation of the motor 4 can rotate the rotating shaft 15, and then the chain 19 can rotate the rotating shaft 2 8 and the fan blade 1 9. At this time, the hose 12, the U-shaped tube 10 and the air outlet can blow air to the power supply body 3 to dissipate heat, thereby achieving air cooling. Then, the control pump body 14 is operated, so that the coolant can circulate in the heat dissipation copper tube 15, the heat dissipation tube 2, the pipe 17 and the box 13. Since the heat dissipation copper tube 15 is in contact with the power supply body 3, the coolant can achieve liquid cooling when it flows.

[0045] In order to achieve the purpose of air circulation inside the shell 1, the present device adopts the following technical solution: a shielding shell 20 is fixedly connected to one side of the cylinder 6, and the shielding shell 20 is sleeved on the outside of the chain 19. Two air-permeable nets 1 21 distributed front and back are fixedly embedded on one side of the shell 1, and an air-permeable net 2 22 is fixedly embedded on the other side of the shell 1. The air-permeable nets 1 21 and 22 can achieve air circulation inside the shell 1.

[0046] Among them, in order to achieve the purpose of constantly changing the position of the air outlet, the present device adopts the following technical solutions: the moving component includes two support blocks 25, the two support blocks 25 are fixedly connected to the inner walls of the front and rear sides of the shell 1, and reciprocating screws 26 are embedded in the two support blocks 25. The bottom ends of the two reciprocating screws 26 pass through the bottom of the shell 1, and the outsides of the two reciprocating screws 26 are sleeved with sliding seats 27. The sliding seats 27 are connected to the reciprocating screws 26 through a ball screw pair. The two sliding seats 27 are fixedly connected to the U-shaped tube 10. The inner walls of the front and rear sides of the shell 1 are fixedly connected with positioning rods 28. The two positioning rods 28 pass through the two sliding seats 27 and are slidably connected thereto. The top of one of the reciprocating screws 26 is fixedly connected to a bevel gear 29. A bevel gear 2 30 is provided on one side of the bevel gear 1 29 and is meshed with the bevel gear 2 30. The bevel gear 2 30 is fixedly sleeved on the outside of the rotating shaft 1 5. The bottom ends of the two reciprocating screws 26 are fixedly sleeved with a sprocket 2 31. The two sprockets 31 are sleeved with a chain 2 32 on the outside. The two sprockets 31 are driven and connected by the chain 2 32. A groove is provided inside the bottom plate 2. The chain 2 32 passes through the groove. The reciprocating screw 26 is connected to the housing 1 and the support block 25 through a bearing. A moving component is designed. When the motor 4 works to rotate the rotating shaft 1 5, the moving component will also work, so that the U-shaped tube 10 can be continuously moved up and down, so that the position of the air outlet can be continuously changed, so that the wind can be evenly blown on the outside of the power supply body 3, thereby increasing the heat dissipation effect.

[0047] Among them, in order to achieve the purpose of cooling the coolant and circulating the air inside the shell 1, the present device adopts the following technical solution: two support rods 33 are fixedly connected to the inner wall of the bottom of the shell 1, and the two support rods 33 are located on the inner side of the heat dissipation copper tube 2 16 and the power supply body 3. A rotating shaft 34 is embedded in the two support rods 33, and a fan blade 2 35 is fixedly sleeved on the outside of the rotating shaft 34 and the rotating shaft 1 5. A sprocket 3 36 is fixedly sleeved on the outside of the two sprockets 36, and a chain 3 37 is sleeved on the outside of the two sprockets 36. 6 are connected by a chain 3 37, and the rotating shaft 34 is connected to the support rod 33 by a bearing. Under the action of the chain 3 37, the rotating shaft 1 5 can also rotate the rotating shaft 34, and the rotation of the rotating shaft 34 can rotate the fan blade 2 35, so that air can be blown to the heat dissipation copper tube 2 16, so as to cool the coolant and ensure the liquid cooling effect. The rotation of the fan blade 2 35 can also quickly circulate the air inside the housing 1, which can also increase the heat dissipation effect of the power supply body 3;

[0048] In order to facilitate the connection of wires, the device is implemented by the following technical solutions: a cover plate 38 is provided on the top of the housing 1, and the cover plate 38 is connected to the housing 1 by bolts. A wire groove 39 is provided inside the cover plate 38, and the wire groove 39 can facilitate the connection of wires between the electrical equipment of the forklift and the power supply body 3;

[0049] Among them, in order to achieve the purpose of reducing wear, the present device adopts the following technical solution: the rotating shaft 5 is connected to the housing 1 through a bearing, and the rotating shaft 8 is connected to the cylinder 6 through a bearing. The bearing connection can reduce wear;

[0050] Among them, in order to facilitate the installation of this device on a forklift, this device is implemented by adopting the following technical solution: the four corners of the bottom of the shell 1 are fixedly connected with a mounting bracket 40, and the four mounting brackets 40 are provided with mounting holes inside. The mounting bracket 40 can facilitate the installation of this device on a forklift.

[0051] The use process of the present invention is as follows: when the power supply body 3 generates heat during use and needs to dissipate the heat, the motor 4 is controlled to work, the motor 4 drives the rotating shaft 15 to rotate, the rotation of the rotating shaft 15 drives the chain 19 to rotate, the rotation of the chain 19 drives the rotating shaft 2 8 to rotate, and the rotation of the rotating shaft 2 8 can cause the fan blade 19 to rotate. Then, under the action of the two hoses 12, the U-shaped tube 10 and the multiple air outlets, the fan blade 19 rotates to blow air to the outside of the power supply body 3 to dissipate heat, thereby achieving air cooling. At this time, the switch valve 24 can be opened, and then coolant is added to the box 13 through the pipe 2 23. Then, the pump body 14 is controlled to work, so that the coolant can circulate in the heat dissipation copper tube 15, the heat dissipation pipe 2, the pipe 17 and the box 13. Since the heat dissipation copper tube 15 is in contact with the power supply body 3, the coolant can achieve liquid cooling when it flows. The two heat dissipation methods can increase the heat dissipation efficiency of the power supply body 3 through the combination of air cooling and liquid cooling, and can dissipate heat in time, thereby preventing the temperature of the power supply body 3 from getting higher and higher, and preventing the power supply body 3 from working in a high temperature environment.

[0052] When the rotating shaft 1 5 rotates, the bevel gear 2 30 can also be rotated, and the rotation of the bevel gear 2 30 drives the bevel gear 1 29 to rotate. The rotation of the bevel gear 1 29 drives the reciprocating screw 26 on the rear side to rotate. The rotation of the reciprocating screw 26 on the rear side drives the chain 2 32 to rotate. The rotation of the chain 2 32 drives the reciprocating screw 26 on the front side to rotate. In this way, the two reciprocating screws 26 can be rotated at the same time. The rotation of the two reciprocating screws 26 drives the two sliding seats 27 to continuously move up and down, thereby causing the U-shaped tube 10 to continuously move up and down. In this way, the position of the air outlet can be continuously changed, so that the wind can be evenly blown to the outside of the power supply body 3, thereby increasing the heat dissipation effect and avoiding the occurrence of heat dissipation dead angles.

[0053] The coolant absorbs heat when it flows. At this time, under the action of chain three 37, the rotation of shaft one 5 can also rotate shaft three 34. The rotation of shaft three 34 can rotate fan blade two 35, so that air can be blown to the heat dissipation copper tube two 16, which can cool the coolant and thus ensure the liquid cooling effect. The rotation of fan blade two 35 can also make the air inside the shell 1 circulate quickly, which can also increase the heat dissipation effect of the power supply body 3.

[0054] The above are merely preferred embodiments of the present invention. Anyone skilled in the art may modify the present invention using the above-described technical solutions or modify them into equivalent technical solutions. Therefore, any simple modification or equivalent replacement based on the technical solutions of the present invention falls within the scope of protection claimed by the present invention.
