The water tank 301 is arranged at an adjacent position of the placement frame 2, one end of the water tank 301 is connected to the water pump 302, and the output end of the water pump 302 is connected to the flat tube 303, which is arranged at the bottom of the placement frame 2, and the top of the water tank 301 is connected to the conical box 304, and the bottom of the conical box 304 The first transmission shaft 306 is rotatably connected to the top center of the conical box 304, and the bottom of the first transmission shaft 306 extends into the columnar tube 305 and is fixedly connected to the turbine blade 307. One end of the flat tube 303 is connected to the heat dissipation component 4, and the heat dissipation component 4 includes a heat dissipation pipe 401 and a return pipe 402. The heat dissipation pipe 401 is arranged at an end away from the water tank 301, one end of the heat dissipation pipe 401 is connected to the flat tube 303, and the other end of the heat dissipation pipe 401 is connected to the return pipe 402, and the return pipe 402 is connected to the conical box 304. The top of the placing frame 2 is connected to the shaped box 304, and an air cooling component 5 is arranged on the top of the placing frame 2. The air cooling component 5 includes a top cover 501, a first connecting shaft 502 and a first fan blade 503. The top cover 501 is arranged on the top of the placing frame 2. The middle of the top cover 501 is rotatably connected to the first connecting shaft 502, and the bottom of the first connecting shaft 502 is fixedly connected to the first fan blade 503. The top of the first transmission shaft 306 and one end of the first connecting shaft 502 are both fixedly connected to the first synchronous wheel 6, and the two first synchronous wheels 6 are driven by the first synchronous belt 601; the bottom of the flat tube 303 extends to the bottom of the base 1, and is fixed The first fin 308 is fixedly connected, and the first fin 308 is wavy. The side wall of the heat dissipation pipe 401 is fixedly connected with a plurality of second fins 414. The side walls at both ends of the water tank 301 are respectively fixedly connected with a plurality of heat dissipation fins 309. The base 1 is located at the placement frame 2 and is provided with a plurality of first heat dissipation holes 101. The side walls at both ends of the placement frame 2 are respectively provided with a plurality of second heat dissipation holes 201. The middle part of the top cover 501 is fixedly connected with a first air guide cover 505. The inner wall of the first air guide cover 505 is fixedly connected with a first fixing frame 506. The first fixing frame 506 is rotatably connected with the first connecting shaft 502.

[0036] In this embodiment, the battery is installed in the placement frame 2. During the driving of the vehicle, the battery will generate heat. At this time, the water pump 302 is turned on. Under the action of the water pump 302, the coolant in the water tank 301 will flow into the flat tube 303. When the coolant flows in the flat tube 303, the heat generated by the battery can be absorbed. The flat tube 303 is arranged in an "S" shape, which can increase the contact area between the flat tube 303 and the battery, so that the coolant can better absorb the heat of the battery. After the coolant absorbs the heat of the battery, its own temperature will increase. The coolant with increased temperature will flow out of the flat tube 303 under the action of the water pump 302. The heat dissipation time of the coolant in the heat dissipation tube 401 can be prolonged. The design of the second fin 414 can increase the heat exchange area of ​​the heat dissipation tube 401, thereby accelerating the heat dissipation of the coolant. In addition, the first fin 308 arranged at the bottom of the flat tube 303 can increase the heat exchange area of ​​the flat tube 303, so that the coolant can absorb the heat of the battery in the flat tube 303. When the coolant passes through the heat pipe 401, it will flow back to the water tank 301 through the return pipe 402, so as to realize the recycling of the coolant. The heat sink 309 arranged in the water tank 301 can further dissipate the heat of the coolant with increased temperature, ensuring that the coolant can effectively cool the battery when it flows into the flat tube 303. In this process, the coolant will first flow into the conical box 304 at the top of the water tank 301, and flow into the columnar tube 305 along the conical box 304, and then pass through the turbine blades 307 in the columnar tube 305. When the coolant passes through the turbine blades 307, it will drive the turbine blades 307 to rotate. 07 rotates, thereby driving the first transmission shaft 306 to rotate, wherein the first transmission shaft 306 and the first connecting shaft 502 are connected together through the first synchronous wheel 6 and the first synchronous belt 601. Therefore, when the first transmission shaft 306 rotates, it can drive the first connecting shaft 502 to rotate, thereby driving the first fan blade 503 to rotate. By rotating the first fan blade 503, the wind generated when the first fan blade 503 rotates will enter the placement frame 2 along the first wind guide cover 505, thereby accelerating the air flow rate in the placement frame 2, allowing the hot air to quickly flow out of the placement frame 2 through the first heat dissipation holes 101 and the second heat dissipation holes 201, thereby improving the heat dissipation effect.

[0037] like Figure 1 , Figure 2 , Figure 7 and Figure 8As shown, the heat dissipation assembly 4 also includes a mounting frame 403, the heat dissipation pipe 401 is arranged in the mounting frame 403, the mounting frame 403 is located at a position adjacent to the heat dissipation pipe 401 and is rotatably connected to two second connecting shafts 404, the second connecting shaft 404 is located at one end of the heat dissipation pipe 401 and is fixedly connected to a second fan blade 405, the other end of the second connecting shaft 404 is fixedly connected to a second synchronous wheel 406, and the two second synchronous wheels 406 are driven by a second synchronous belt 407; the top of the mounting frame 403 is rotatably connected to a second transmission shaft 408, and one end of the second transmission shaft 408 is fixedly connected to A second bevel gear 409, one end of which is meshedly connected with the first bevel gear 504, the first bevel gear 504 is fixedly connected to the first connecting shaft 502, the second transmission shaft 408 and one end of one of the second connecting shafts 404 are fixedly connected with a third synchronous wheel 410, and the two third synchronous wheels 410 are driven by a third synchronous belt 411; one end of the mounting frame 403 is fixedly connected with two second air guide covers 412, the inner wall of the second air guide cover 412 is fixedly connected with a second fixing frame 413, and the second fixing frame 413 is rotatably connected with the second connecting shaft 404;

[0038] In this embodiment, the two second connecting shafts 404 are connected together by the second synchronous wheel 406 and the second synchronous belt 407, and the second transmission shaft 408 and one of the second connecting shafts 404 are connected together by the third synchronous wheel 410 and the third synchronous belt 411, so that the two second connecting shafts 404 and the second transmission shaft 408 can rotate synchronously. When the first connecting shaft 502 is driven by the first transmission shaft 306 to rotate, it will drive the first bevel gear 504 to rotate, thereby driving the second bevel gear 409 to rotate, and then driving the second transmission shaft 408 to rotate. When the second transmission shaft 408 rotates, it can drive the two second connecting shafts 404 to rotate, thereby driving the two second fan blades 405 to rotate. During the rotation of the second fan blades 405, the flow speed of the air on the surface of the heat pipe 401 can be accelerated, so that the coolant in the heat pipe 401 can be quickly cooled down. Through the design of the second wind guide cover 412, the wind generated when the second fan blades 405 rotate can accurately act on the heat pipe 401, thereby ensuring the heat dissipation effect.

[0039] like Figure 1 , Figure 2 , Figure 4 , Fig. 9 , Fig.10 , Fig.11 and Fig.12As shown, the input end of the water pump 302 is connected with the water inlet pipe 310, the water inlet pipe 310 is connected with the water tank 301, the output end of the water pump 302 is connected with the water outlet pipe 311, one end of the water outlet pipe 311 is connected with the first diverter box 7, one end of the side wall of the first diverter box 7 is connected with the first connecting pipe 701, one end of the flat tube 303 is connected with the input pipe 312, the input pipe 312 is connected with the first connecting pipe 701; the end of the flat tube 303 away from the input pipe 312 is connected with the output pipe 313, one end of the output pipe 313 is connected with the second connecting pipe 801, one end of the second connecting pipe 801 is connected with the second diverter box 8, one end of the side wall of the second diverter box 8 is connected with the third connecting pipe 802, one end of the third connecting pipe 802 is connected with the heat dissipation pipe 401, the top of the first diverter box 7 is connected with the branch pipe 9, one end of the branch pipe 9 is connected with the first The tops of the two shunt boxes 8 are connected; a hydraulic cylinder 702 is fixedly connected to one end of the bottom of the inner wall of the first shunt box 7, a connecting frame 703 is fixedly connected to the output end of the hydraulic cylinder 702, a blocking block 704 is fixedly connected to the top of the connecting frame 703, and the blocking block 704 is located directly below the input end of the branch pipe 9. The inner wall of the first shunt box 7 is located at the input end of the first connecting pipe 701 and is slidably connected to a gate plate 705, and the connecting frame 703 is fixedly connected to the gate plate 705; the output end of the second connecting pipe 801 and the output end of the branch pipe 9 both extend to the inside of the second shunt box 8, and a cover plate 803 is rotatably connected to one end of the inner wall of the second shunt box 8, and a first protrusion 804 that fits with the output end of the second connecting pipe 801 is fixedly connected to one end of the cover plate 803, and a second protrusion 805 that fits with the output end of the branch pipe 9 is fixedly connected to the other end of the cover plate 803;

[0040] In the present embodiment, since it takes a certain amount of time for the temperature-increased coolant to dissipate heat in the heat dissipation pipe 401, and the coolant in the flat tube 303 will not immediately rise from a low temperature state to a high temperature state when absorbing the heat of the battery, the design of the first shunt box 7 and the second shunt box 8 allows the coolant to skip the flat tube 303 and circulate only between the water tank 301, the water pump 302 and the heat dissipation pipe 401, so that the coolant that has absorbed the heat of the battery has enough time to dissipate heat. When it is necessary to circulate the coolant between the water tank 301, the water pump 302 and the heat dissipation pipe 401, the hydraulic cylinder 702 is now opened. Under the drive of the hydraulic cylinder 702, the connecting frame 703 moves downward, driving the gate plate 705 to move downward, and the first The input end of the connecting pipe 701 is blocked, so that the coolant cannot flow into the flat tube 303 through the first connecting pipe 701. At the same time, when the connecting frame 703 moves downward, it can drive the blocking block 704 to move downward, so that the input end of the branch pipe 9 is opened, so that the coolant skips the flat tube 303 through the branch pipe 9 and directly flows into the second diverter box 8. When the coolant flows out from the output end of the branch pipe 9, it drives the cover plate 803 to rotate, so that the cover plate 803 covers the output end of the second connecting pipe 801, so as to avoid the coolant being radiated from mixing with the coolant in the flat tube 303, affecting the heat dissipation effect. When the cover plate 803 covers the output end of the second connecting pipe 801, the first protrusion 804 will be embedded in the output port of the second connecting pipe 801. The output port of the second connecting pipe 801 is blocked, thereby improving the sealing performance. Then the coolant that needs to dissipate heat flows into the heat dissipation pipe 401 for heat dissipation. Through this design, the coolant in the water tank 301 can repeatedly flow into the heat dissipation pipe 401 for heat dissipation, ensuring that the coolant has a better cooling effect when used subsequently. When the heat dissipation of the coolant is completed, the hydraulic cylinder 702 is opened again, and the hydraulic cylinder 702 drives the connecting frame 703 to move upward, thereby driving the blocking block 704 to move upward, allowing the blocking block 704 to block the input port of the branch pipe 9, and at the same time drive the gate plate 705 to move upward, so that the input port of the first connecting pipe 701 is in an open state. In this way, when the water pump 302 transports the coolant to the first diverter box 7, the coolant can The coolant flows into the flat tube 303 through the first connecting tube 701 and cools the battery. The coolant flowing out of the flat tube 303 flows into the second diverter box 8 through the second connecting tube 801. In the process of the coolant flowing out of the output port of the second connecting tube 801, the cover plate 803 is driven to rotate, so that the cover plate 803 blocks the output port of the branch pipe 9 to prevent the coolant from flowing into the branch pipe 9. When the cover plate 803 covers the output port of the branch pipe 9, the first protrusion 804 is embedded in the output port of the branch pipe 9, thereby blocking the output port of the branch pipe 9, thereby improving the sealing. At this time, the coolant will flow into the heat dissipation pipe 401 through the third connecting tube 802, and finally flow back to the water tank 301 through the reflux pipe 402 at one end of the heat dissipation pipe 401.

[0041] Working principle: when the battery needs to be cooled, the water pump 302 is turned on first. Under the action of the water pump 302, the coolant in the water tank 301 will flow into the flat tube 303. When the coolant flows in the flat tube 303, the heat generated by the battery can be absorbed. After the coolant absorbs the heat of the battery, its own temperature will increase. The coolant with increased temperature will flow out of the flat tube 303 under the action of the water pump 302 and flow into the heat dissipation pipe 401 for heat dissipation, so that the coolant has a better cooling effect in subsequent use. After the coolant passes through the heat dissipation pipe 401, it will flow back to the water tank 301 through the reflux pipe 402, thereby realizing the recycling of the coolant, wherein the heat sink 309 arranged in the water tank 301 can The coolant with increased temperature is further radiated to ensure that the coolant can effectively cool the battery when it flows into the flat tube 303. During this process, the coolant will first flow into the conical box 304 at the top of the water tank 301, and flow into the columnar tube 305 along the conical box 304, and then pass through the turbine blades 307 in the columnar tube 305. In the process of the coolant passing through the turbine blades 307, the turbine blades 307 will be driven to rotate, thereby driving the first transmission shaft 306 to rotate, wherein the first transmission shaft 306 and the first connecting shaft 502 are connected together through the first synchronous wheel 6 and the first synchronous belt 601. Therefore, when the first transmission shaft 306 rotates, it can drive the first connecting shaft 502 to rotate, thereby driving the first fan blade 503 to rotate. By rotating the first blade 503, the wind generated by the rotation of the first blade 503 will enter the placement frame 2 along the first wind guide cover 505, thereby accelerating the air flow rate in the placement frame 2, allowing the hot air to quickly flow out of the placement frame 2 through the first heat dissipation hole 101 and the second heat dissipation hole 201, thereby improving the heat dissipation effect. When the first connecting shaft 502 is driven by the first transmission shaft 306 to rotate, it will drive the first bevel gear 504 to rotate, thereby driving the second bevel gear 409 to rotate, and then driving the second transmission shaft 408 to rotate. When the second transmission shaft 408 rotates, it will drive the third synchronous belt 411 and the third synchronous wheel 410 to rotate, thereby driving one of the second connecting shafts 404 to rotate, wherein the two second connecting shafts 404 are driven by The second synchronous wheel 406 and the second synchronous belt 407 are connected together by transmission. Therefore, when the second transmission shaft 408 rotates, the two second connecting shafts 404 can be driven to rotate, thereby driving the two second fan blades 405 to rotate. During the rotation of the second fan blades 405, the flow speed of the air on the surface of the heat pipe 401 can be accelerated, so that the coolant in the heat pipe 401 can be quickly cooled down. Through the design of the second wind guide cover 412, the wind generated when the second fan blades 405 rotate can accurately act on the heat pipe 401, thereby ensuring the heat dissipation effect. Since it takes a certain amount of time for the temperature-increased coolant to dissipate heat in the heat pipe 401, and the coolant in the flat tube 303 will not immediately rise from a low temperature state to a high temperature state when absorbing the heat of the battery,Therefore, through the design of the first shunt box 7 and the second shunt box 8, the coolant can skip the flat tube 303 and circulate only between the water tank 301, the water pump 302 and the heat dissipation tube 401, so that the coolant that absorbs the heat of the battery has enough time to dissipate heat. When the coolant needs to circulate between the water tank 301, the water pump 302 and the heat dissipation tube 401, the hydraulic cylinder 702 is opened. Under the drive of the hydraulic cylinder 702, the connecting frame 703 will move downward, thereby driving the gate plate 705 to move downward, so as to block the input end of the first connecting tube 701, so that the coolant cannot flow into the flat tube 303 through the first connecting tube 701, and at the same time, when the connecting frame 703 moves downward, the gate plate 705 is blocked. When the cover plate 803 is in motion, it can drive the blocking block 704 to move downward, so that the input end of the branch pipe 9 is in an open state, so that the coolant can jump over the flat tube 303 through the branch pipe 9 and directly flow into the second diverter box 8. When the coolant flows out from the output end of the branch pipe 9, it will drive the cover plate 803 to rotate, so that the cover plate 803 covers the output end of the second connecting pipe 801, so as to prevent the coolant being radiated from mixing with the coolant in the flat tube 303 and affecting the heat dissipation effect. When the cover plate 803 covers the output end of the second connecting pipe 801, the first protrusion 804 will be embedded in the output port of the second connecting pipe 801, thereby blocking the output port of the second connecting pipe 801, thereby improving the sealing performance. Then you need The heat dissipated coolant will flow into the heat dissipation pipe 401 for heat dissipation. Through this design, the coolant in the water tank 301 can repeatedly flow into the heat dissipation pipe 401 for heat dissipation, ensuring that the coolant has a good cooling effect when used subsequently. When the heat dissipation of the coolant is completed, the hydraulic cylinder 702 is opened again, and the hydraulic cylinder 702 drives the connecting frame 703 to move upward, thereby driving the blocking block 704 to move upward, allowing the blocking block 704 to block the input port of the branch pipe 9, and at the same time drive the gate plate 705 to move upward, so that the input port of the first connecting pipe 701 is in an open state. In this way, when the water pump 302 transports the coolant to the first diverter box 7, the coolant can flow into the flat The coolant flows out of the flat tube 303 and flows into the second shunt box 8 through the second connecting tube 801. When the coolant flows out of the output port of the second connecting tube 801, the cover plate 803 is driven to rotate, so that the cover plate 803 blocks the output port of the branch pipe 9 to prevent the coolant from flowing into the branch pipe 9. When the cover plate 803 covers the output port of the branch pipe 9, the first protrusion 804 is embedded in the output port of the branch pipe 9, thereby blocking the output port of the branch pipe 9, thereby improving the sealing performance. At this time, the coolant flows into the heat dissipation pipe 401 through the third connecting tube 802, and finally flows back to the water tank 301 through the return pipe 402 at one end of the heat dissipation pipe 401.
