With the maturity of hybrid vehicle technology, it has also been widely used in existing heavy trucks, with the advantages of energy saving and low emissions.

[0040] like Figures 1 to 9As shown, an embodiment of the present invention provides a heat dissipation system for a heavy-duty hybrid truck. The heavy-duty hybrid truck includes a motor 1 and a water tank 2. The heat dissipation system for the heavy-duty hybrid truck includes: a water cooling device 3, an air cooling device 4, a guide device 5 and a filtering device 6.

[0041] The water tank 2 is provided with a water cooler 21 and a water supply pipe 22 . The water supply pipe 22 is provided at the top of the water tank 2 and is connected to the water tank 2 . The water supply pipe 22 is used to supply external cooling water to the inside of the water tank 2 .

[0042] The water cooler 21 is connected to the water tank 2 and is disposed on the front end surface of the water tank 2. The water cooler 21 is used to cool the cooling water inside the water tank 2 so that the cooling water in the water tank 2 can be reduced to a certain temperature to enhance the heat dissipation effect on the motor 1. A cleaning door 23 is rotatably disposed on the water tank 2. The operator can open the water tank 2 through the cleaning door 23 to clean the filter device 6 to ensure the filter device 6 has the effect of filtering the cooling water after cooling the motor 1.

[0043] The water cooling device 3 and the air cooling device 4 are respectively arranged at the shaft extension end and the fan end of the motor 1, so that the water cooling device 3 and the air cooling device 4 cool the shaft extension end and the fan end respectively, thereby ensuring that the motor 1 can be cooled in all directions.

[0044] The water cooling device 3 includes a mounting ring 31, a cleaning ring tube 32, a plurality of first cleaning nozzles 33 and a collecting groove 34. The mounting ring 31 is sleeved on the outer wall of the shaft extension end, the cleaning ring tube 32 is arranged in the inner wall of the mounting ring 31, and the plurality of first cleaning nozzles 33 are arranged at intervals along the circumference of the cleaning ring tube 32, and the first cleaning nozzles 33 are connected to the cleaning ring tube 32. The first cleaning nozzles 33 are arranged toward the shaft extension end of the motor 1, and the collecting groove 34 is recessed in the inner wall of the mounting ring 31.

[0045] The guide device 5 is located at the top of the mounting circle 31 , and is connected to the cleaning circle tube 32 and the water tank 2 respectively, and is used to guide the cooling water in the water tank 2 into the cleaning circle tube 32 so that the first cleaning nozzle 33 can spray the cooling water onto the surface of the motor 1 .

[0046] The filter device 6 is in communication with the collecting tank 34 and is used for filtering the cooling water after cooling the motor 1 .

[0047] Specifically, the first cleaning nozzle 33 is arranged obliquely toward the shaft extension end of the motor 1 so that the first cleaning nozzle 33 sprays the cooling water obliquely, which can increase the cooling water spraying area and dissipate heat from the surface of the motor 1.

[0048] When the temperature of the motor 1 is high, the guide device 5 connected to the water tank 2 introduces cold water into the cleaning circle tube 32, and the cooling water is sprayed onto the surface of the motor 1 through the first cleaning nozzle 33 to cool the motor 1; the cooling water sprayed onto the surface of the motor 1 finally flows into the collecting tank 34 through the surface of the motor 1, and after being filtered by the filtering device 6, it is re-introduced into the water tank 2, thereby realizing the recycling of cooling water.

[0049] In addition, the motor 1 is cooled by blowing air through the air cooling device 4 arranged at the fan end of the motor 1, thereby achieving sufficient heat dissipation for the motor 1.

[0050] The present invention is achieved by sleeve-mounting the mounting ring 31 on the outer wall of the shaft extension end, the cleaning ring tube 32 is arranged in the inner wall of the mounting ring 31, the first cleaning nozzles 33 are arranged at intervals along the circumference of the cleaning ring tube 32, and the first cleaning nozzles 33 are connected to the cleaning ring tube 32, the first cleaning nozzles 33 are arranged toward the shaft extension end of the motor 1, and the collecting groove 34 is recessed in the inner wall of the mounting ring 31; the guide device 5 is located at the top of the mounting ring 31, the guide device 5 is respectively connected to the cleaning ring tube 32 and the water tank 2, and the filtering device 6 is connected to the collecting groove 34. When the temperature of the motor 1 is high, the guide device 5 connected to the water tank 2 introduces cold water into the cleaning circle tube 32, so that the cooling water is sprayed onto the surface of the motor 1 through the first cleaning nozzle 33, so as to cool the motor 1, and the cooling water is collected by the collecting tank 34, so that the cooling water is filtered by the cooling water filter device 6 through the filter component and then reintroduced into the water tank 2, so as to realize the recycling of the cooling water. In addition, the air cooling device 4 arranged at the fan end of the motor 1 is used to blow air to dissipate the heat of the motor 1, so as to achieve sufficient heat dissipation of the motor 1, greatly reduce the damage of the heat to the motor 1, and increase the service life of the motor 1.

[0051] In one embodiment of the heat dissipation system for a heavy-duty hybrid truck of the present invention, Figures 1 to 5 As shown, the water cooling device 3 further includes a rotating portion 35 and a moving portion 36 . The rotating portion 35 is used to drive the cleaning ring tube 32 to rotate, and the moving portion 36 is used to drive the installation ring 31 to move.

[0052] The rotating part 35 includes a transmission ring 351 and a driving motor 352 . The transmission ring 351 is disposed on the mounting ring 31 and is rotationally connected to the mounting ring 31 . The driving motor 352 is connected to the transmission ring 351 to drive the transmission ring 351 to rotate.

[0053] Specifically, when the first cleaning nozzle 33 sprays cooling water to the motor 1, the driving motor 352 is started, and the driving motor 352 drives the transmission ring 351 to rotate. The rotation of the transmission ring 351 drives the cleaning circle tube 32 and multiple first cleaning nozzles 33 to rotate, so that the first cleaning nozzle 33 can spray the outer surface of the shaft extension end in all directions, further improving the cooling effect.

[0054] At the same time, the moving part 36 drives the mounting ring 31 to move laterally, thereby increasing the coverage of the cooling water sprayed by the first cleaning nozzle 33, and further achieving all-round spraying of the outer surface of the shaft extension end.

[0055] It should be noted that the rotational connection between the transmission ring 351 and the mounting ring 31 may be achieved by a dovetail groove, a block structure, or by other structures, which are not limited here.

[0056] In one embodiment of the heat dissipation system for a heavy-duty hybrid truck of the present invention, Figure 4 As shown, the rotating part 35 also includes a transmission gear 353, a first rotating shaft 354 and a transmission ring gear 355. The transmission ring gear 355 is arranged on the outer peripheral wall of the transmission ring 351. The first end of the first rotating shaft 354 is connected to the output shaft of the driving motor 352, and the second end of the first rotating shaft 354 is connected to the transmission gear 353. The transmission gear 353 is meshed with the transmission ring gear 355.

[0057] Specifically, when the first cleaning nozzle 33 sprays cooling water to the motor 1, the driving motor 352 starts to drive the transmission ring gear 355 to rotate, and the transmission ring gear 353 meshing with it rotates, thereby driving the transmission ring 351 to rotate, so that the transmission ring 351 can rotate stably on the mounting ring 31.

[0058] In one embodiment of the heat dissipation system for a heavy-duty hybrid truck of the present invention, Figure 5 As shown, the moving part 36 includes a fixed plate 361, a driving cylinder 362, a connecting plate 363, a connecting shaft 364 and an eccentric wheel. The fixed plate 361 is arranged on the side wall of the water tank 2, the driving cylinder 362 is fixed on the fixed plate 361, the side wall of the connecting plate 363 is connected to the mounting ring 31, the output shaft of the driving motor 352 is connected to the first end of the connecting shaft 364, and the second end of the connecting shaft 364 passes through the fixed plate 361 and is connected to the connecting plate 363.

[0059] Specifically, when the first cleaning nozzle 33 sprays cooling water to the motor 1, the driving cylinder 362 is started, and the driving cylinder 362 drives the connecting shaft 364 to move toward the fan end of the motor 1 or away from the fan end of the motor 1, thereby driving the connecting plate 363 to move toward the fan end of the motor 1 or away from the fan end of the motor 1, so that the connecting plate 363 moves back and forth, thereby driving the mounting ring 31 to move back and forth at the shaft extension end of the motor 1, so that the first cleaning nozzle 33 on the cleaning circle tube 32 fully sprays water to cool the surface of the motor 1, thereby greatly improving the cooling effect on the motor 1.

[0060] Furthermore, the water cooling device 3 also includes a guide rod 37 and a guide plate. The guide plate is arranged on the side wall of the water tank 2 located on one side of the electric fan of the motor 1. The first end of the guide rod 37 is connected to the guide plate, and the second end of the guide rod 37 passes through the connecting plate 363 and is connected to the fixed plate 361. There are multiple guide rods 37, and the multiple guide rods 37 are evenly spaced along the length direction of the guide plate, so that when the driving cylinder 362 drives the connecting plate 363 to move, the moving direction of the connecting plate 363 is limited by the guide rod 37, thereby avoiding the problem that the moving direction of the connecting plate 363 deviates and causes the mounting ring 31 to collide with the motor 1.

[0061] In one embodiment of the heat dissipation system for a heavy-duty hybrid truck of the present invention, Figure 1 As shown, the flow guide device 5 includes a first water pump 51, a first hose 52, a first connecting pipe 53 and a second hose 54. The first water pump 51 is arranged on the top of the water tank 2. The two ends of the first hose 52 are connected to the first water pump 51 and the first connecting pipe 53 respectively. The first connecting pipe 53 is connected to the first end of the second hose 54, and the second end of the second hose 54 is connected to the cleaning circle tube 32. The first water pump 51 is used to pump the cooling water inside the water tank 2 into the first hose 52.

[0062] Specifically, the first water pump 51 extends into the water tank 2 and is connected to the cooling water inside the water tank 2, thereby pumping out the cooling water inside the water tank 2 and introducing it into the first hose 52, and then introducing the cooling water into the first connecting pipe 53 and the second hose 54 through the first hose 52, so that the cooling water is introduced into the cleaning circle tube 32 and multiple first cleaning nozzles 33, and sprayed onto the outer surface of the motor 1.

[0063] The present invention arranges the first water pump 51 on the top of the water tank 2, and the two ends of the first hose 52 are connected to the first water pump 51 and the first connecting pipe 53 respectively, the first connecting pipe 53 is connected to the first end of the second hose 54, and the second end of the second hose 54 is connected to the cleaning circle tube 32, so that the cooling water inside the water tank 2 can be quickly pumped out through the first water pump 51, and the cooling water is sprayed to the outer surface of the motor 1 through the first cleaning nozzle 33, thereby improving the water supply rate and effectively ensuring the cooling effect on the motor 1.

[0064] Further, such as Figure 1 and Figure 6 As shown, the heat dissipation system for a heavy-duty hybrid truck of the present invention further includes a dust removal device 7, which includes a connecting block 71, a camera 72, a cleaning pipe 73, and a second cleaning nozzle 74. The connecting block 71 is fixed on the mounting ring 31, the camera 72 is arranged on the connecting block 71, the first end of the cleaning pipe 73 is connected to the first connecting pipe 53, the second end of the cleaning pipe 73 is connected to the second cleaning nozzle 74, and the second end of the cleaning pipe 73 extends to the upper end surface of the motor 1 and is arranged toward the upper end surface of the motor 1. The camera 72 is used to detect dust on the outer surface of the motor 1.

[0065] When the camera 72 detects that a large amount of dust or dirt adheres to the surface of the motor 1, the heat dissipation effect of the motor 1 will be affected. Therefore, the cleaning pipe 73 is connected to the first connecting pipe 53, so that the cooling water of the first connecting pipe 53 can be diverted to the cleaning pipe 73, and the surface of the motor 1 is washed by the second cleaning nozzle 74, so that the surface is cleaned and the heat dissipation effect of the motor 1 is improved.

[0066] In one embodiment of the heat dissipation system for a heavy-duty hybrid truck of the present invention, Figures 1 to 7 As shown, the filtering device 6 includes a drain pipe 61, a third hose 62, a second water pump 63, a second connecting pipe 64, and a filter screen plate 65, a collecting filter screen slot 66 and a cleaning brush 67 arranged inside the water tank 2. The drain pipe 61 is arranged at the bottom of the mounting ring 31, and the drain pipe 61 is connected to the collecting slot 34. The second water pump 63 is arranged at the bottom of the water tank 2. The two ends of the third hose 62 are respectively connected to the drain pipe 61 and the second water pump 63. The first end of the second connecting pipe 64 is connected to the second water pump 63. The second end of the second connecting pipe 64 extends to the top of the water tank 2 and passes through the water tank 2.

[0067] The collecting filter screen slot 66 is arranged on both sides of the bottom of the filter screen, and the cleaning brush 67 is slidably arranged on the upper part of the filter screen to clean the filter residue on the filter screen into the collecting filter screen slot 66.

[0068] Specifically, the filter screen plate 65 , the collection filter screen slot 66 and the cleaning brush 67 are located below the second end of the second connecting pipe 64 .

[0069] A support plate is provided inside the water tank 2, and the support plate is provided in the middle position inside the water tank 2. The two ends of the filter screen plate 65 are respectively connected to the support plate and the side wall of the water tank 2. In addition, there are multiple filter screen plates 65, collection filter screen slots 66 and cleaning brushes 67, which are arranged at intervals from the top to the bottom of the water tank 2. It should be noted that the filter holes of the multiple filter screen plates 65 are gradually reduced from the top to the bottom of the water tank 2, which can increase the filtering effect of the filter residue in the cooling water.

[0070] Moreover, a slide bar is provided on the side wall of the water tank 2, and a cleaning brush 67 is slidably provided on the slide bar, so that the filter residue on the filter screen plate 65 can be scraped into the collecting filter screen groove 66 on both sides of the bottom of the filter screen, so that the cooling water can be filtered through the filter screen plate 65 and then reused.

[0071] In addition, an electromagnetic valve is provided on the drain pipe 61. When the electromagnetic valve is opened, the cooling water in the drain pipe 61 can be discharged from the electromagnetic valve to the surface of the motor 1, so that the sludge on the surface of the motor 1 is cleaned and discharged to the outside, thereby realizing automatic cleaning of the motor 1 and ensuring the normal heat dissipation effect of the motor 1.

[0072] In one embodiment of the heat dissipation system for a heavy-duty hybrid truck of the present invention, Figure 5 and Figure 7 As shown, the filter device 6 further includes a transmission iron block 68 and an electromagnet block 69. The transmission iron block 68 is arranged on the cleaning brush 67, and the electromagnet block 69 is arranged on the water tank 2. A coil is arranged on the electromagnet block 69.

[0073] Specifically, the electromagnet block 69 is arranged on the outer wall of the water tank 2 and on the side wall of the water tank 2 near the connecting plate 363. When the cooling water enters the water tank 2 through the second connecting pipe 64, it then enters the filter screens 65 in the water tank 2. At this time, the cooling water after heat dissipation is filtered through the filter screens 65, and some impurities in the water are filtered. The surface of the motor 1 is cleaned once before each heat dissipation, so there are fewer impurities in the water at this time.

[0074] When the motor 1 is subjected to water cooling treatment, the coil is energized and currents in different directions are introduced into the coil, so that the electromagnet block 69 generates magnetic field forces in different directions. At this time, the magnetic field forces in different directions generated by the electromagnet block 69 generate suction and thrust on the transmission iron block 68 on the cleaning brush 67, so that the transmission iron block 68 drives the cleaning brush 67 to move back and forth on the slide rod, thereby allowing the cleaning brush 67 to clean the impurities filtered on the surface of the filter screen plate 65 and push them into the collection filter screen slot 66 for collection.

[0075] The filtered cooling water flows into the bottom of the water tank 2, and then the filtered water is pumped into the water cooler 21 for cooling through the water cooler 21; the cooled cooling water is reintroduced into the water tank 2 for reuse, thereby realizing the recycling of the cooling water in the water tank 2, while reducing the water temperature, and further improving the heat dissipation effect of the motor 1. At the same time, during use, the water in the water supply tank 2 on the truck can be replenished into the water tank 2 through the water replenishment pipe 22 through the water pump and the pipeline, so as to replenish the water in the water tank 2.

[0076] The invention itself sets the transmission iron block 68 on the cleaning brush 67, the electromagnet block 69 on the water tank 2, and a coil on the electromagnet block 69, and transmits currents in different directions to the coil, so that the electromagnet block 69 generates magnetic field forces in different directions. At this time, the magnetic field forces in different directions generated by the electromagnet block 69 generate suction and thrust on the transmission iron block 68 on the cleaning brush 67, so that the transmission iron block 68 drives the cleaning brush 67 to move back and forth on the slide rod, so that the cleaning brush 67 cleans the impurities filtered on the surface of the filter screen plate 65 and pushes them into the collection filter screen slot 66 for collection, thereby preventing the filter screen plate 65 from being blocked and causing the problem of poor filtering.

[0077] In one embodiment of the heat dissipation system for a heavy-duty hybrid truck of the present invention, Figures 1 to 9 As shown, the air cooling device includes a mounting plate 41, a first blade 42, a second blade 43 and a transmission part 46. The mounting plate 41 is fixed on the water tank 2 located at the fan end. The transmission part 46 is arranged on the mounting plate 41. The first blade 42 and the second blade 43 are respectively connected to the transmission part 46. The second blade 43 is located between the mounting plate 41 and the fan end. The second blade 43 is arranged parallel to the end face of the fan end, and the first blade 42 is arranged perpendicular to the end face of the fan end.

[0078] Specifically, when the truck is traveling at high speed, the wind during driving cools the shaft extension end of the motor 1, and the wind generated during driving drives the air cooling device at the fan end of the motor 1 to operate. The air cooling device at the fan end of the motor 1 blows air to dissipate the heat of the motor 1, thereby achieving sufficient heat dissipation for the motor 1 during driving of the truck, greatly reducing the damage to the motor 1 caused by heat, and increasing the service life of the motor 1.

[0079] Specifically, when the truck is traveling at high speed, the wind drives the first blade 42 to rotate, the first blade 42 drives the transmission part 46 to rotate, and the rotation of the transmission part 46 drives the second blade 43 to rotate. Through the action of the first blade 42 and the second blade 43, the wind generated by the first blade 42 and the second blade 43 can be blown toward the fan end, thereby taking away the heat generated by the fan end of the motor 1, effectively dissipating the heat from the fan end of the motor 1.

[0080] In one embodiment of the heat dissipation system for a heavy-duty hybrid truck of the present invention, Figure 8 and Fig. 9 As shown, there are a plurality of second blades 43 , and the second blades 43 are evenly spaced apart along the length direction of the mounting plate 41 .

[0081] The air cooling device also includes a first transmission shaft 44, a plurality of second rotating shafts 45 and a transmission belt 47. The first end of the first transmission shaft 44 passes through the mounting plate 41 and is connected to the first end of a second rotating shaft 45. The second end of the first transmission shaft 44 is connected to the transmission part 46. The second end of the second rotating shaft 45 is connected to the second fan blade 43. The transmission belt 47 is respectively mounted on two adjacent second rotating shafts 45.

[0082] Specifically, when the transmission part 46 rotates, the transmission part 46 can drive a second rotating shaft 45 to rotate. Since the transmission belt 47 is respectively mounted on two adjacent second rotating shafts 45, when one second rotating shaft 45 rotates, the transmission belt 47 can make multiple second rotating shafts 45 rotate synchronously, thereby driving multiple second fan blades 43 to rotate.

[0083] The present invention connects the first end of the first transmission shaft 44 through the mounting plate 41 and the first end of the second rotating shaft 45, the second end of the first transmission shaft 44 is connected to the transmission part 46, the second end of the second rotating shaft 45 is connected to the second fan blade 43, and the transmission belt 47 is respectively sleeved on two adjacent second rotating shafts 45. Under the action of the transmission belt 47, the multiple second fan blades 43 achieve synchronous rotation, thereby further improving the heat dissipation effect of the fan end of the motor 1.

[0084] In one embodiment of the heat dissipation system for a heavy-duty hybrid truck of the present invention, Figure 8 and Fig. 9 As shown, the transmission part 46 includes a transmission box 461, a second transmission shaft 462, a first bevel gear 463 and a second bevel gear 464, the first bevel gear 463 and the second bevel gear 464 are located inside the transmission box 461, the transmission box 461 is connected to the mounting plate 41, the first end of the second transmission shaft 462 is connected to the first fan blade 42, the second end of the second transmission shaft 462 passes through the transmission box 461 and is connected to the first bevel gear 463, the second end of the first transmission shaft 44 passes through the transmission box 461 and is connected to the second bevel gear 464, and the first bevel gear 463 is meshed with the second bevel gear 464.

[0085] Specifically, when the truck is traveling at high speed, the wind drives the first fan blade 42 to rotate, the first fan blade 42 drives the second transmission shaft 462 to rotate, the rotation of the second transmission shaft 462 drives the first bevel gear 463 and the second bevel gear 464 meshing with the first bevel gear 463 to rotate, the rotation of the second bevel gear 464 drives a second rotating shaft 45 to rotate, because the transmission belt 47 is respectively mounted on two adjacent second rotating shafts 45, and then when a second rotating shaft 45 rotates, the transmission belt 47 can make multiple second rotating shafts 45 rotate synchronously, and then drive multiple second fan blades 43 to rotate, so that the multiple second fan blades 43 can fully blow air and dissipate heat to the fan end of the motor 1, and at the same time, the shaft extension end of the motor 1 is blown and dissipated by the wind, so that the truck can fully dissipate heat on the surface of the motor 1 when driving normally, greatly reducing the damage of heat to the motor 1 and improving the service life of the motor 1.
