Description

Technical Field

[0001] This application belongs to the technical field of engineering vehicles, and particularly relates to a motor and electronic control heat dissipation structure for new energy engineering vehicles. Background Art

[0002] Engineering vehicles are equipment used for transporting materials such as ores and slag. With the strong support of the country for new energy, new energy engineering vehicles have gradually entered the market. The common new energy engineering vehicles are of two types, namely pure electric and hybrid. Since the pure electric engineering vehicles have a long charging time, while the hybrid engineering vehicles have the advantages of a long cruising range and fast energy replenishment, the hybrid engineering vehicles are thus widely used.

[0003] For hybrid engineering vehicles, they have a drive motor, an ISG motor, and a heat dissipation structure for dissipating heat from the drive motor and the ISG motor. The heat dissipation structure includes a radiator core and a cooling fan provided on the radiator core. The radiator core has a circulation pipeline connected to the cooling channels of the drive motor and the ISG motor. A water pump is provided in the circulation pipeline so that the cooling medium inside the radiator core enters the cooling channels of the drive motor and the ISG motor under the action of the water pump to achieve the cooling of the drive motor and the ISG motor. However, when the hybrid engineering vehicle is working, the heat generated by the drive motor and the ISG motor is different, which then causes the temperatures of the drive motor and the ISG motor to be different. In this way, the heat dissipation timing required by the ISG motor and the drive motor is different, and the drive motor and the ISG motor are both connected to the same radiator core, thus resulting in a high energy consumption of the heat dissipation structure. Summary of the Utility Model

[0004] This application provides a motor and electronic control heat dissipation structure for new energy engineering vehicles to reduce the energy consumption of the heat dissipation structure.

[0005] The technical solution adopted in this application is as follows:

[0006] A motor and electronic control heat dissipation structure for a new energy engineering vehicle, comprising an integrated frame, a first radiator core body arranged on the integrated frame, a second radiator core body arranged on the integrated frame, a first water pump and a second water pump. A first cooling fan is arranged on one side of the first radiator core body, and a second cooling fan is arranged on one side of the second radiator core body. The first water pump is used to connect the cooling channels of the first radiator core body, the motor controller and the drive motor, so that the cooling medium in the first radiator core body enters the cooling channels of the motor controller and the drive motor through the first water pump to dissipate heat from the motor controller and the drive motor. The second water pump is used to connect the second radiator core body, the ISG controller and the ISG motor, so that the cooling medium in the second radiator core body enters the cooling channels of the ISG controller and the ISG motor through the second water pump to dissipate heat from the ISG controller and the ISG motor.

[0007] By adopting the above technical solution, when dissipating heat from the drive motor of the new energy engineering vehicle, the first water pump and the first cooling fan are started. Then, the first cooling fan dissipates heat from the first radiator core body, and the first water pump pumps the cooling medium in the first radiator core body to the cooling channels of the motor controller and the drive motor, thereby realizing the heat dissipation of the drive motor and the motor controller. When dissipating heat from the ISG motor, the second water pump and the second cooling fan are started. Then, the second cooling fan dissipates heat from the second radiator core body, and the second water pump pumps the cooling medium in the second radiator core body to the cooling channels of the ISG controller and the ISG motor to realize the heat dissipation of the ISG controller and the ISG motor. Since the motor and electronic control heat dissipation structure in this application includes a first radiator core body and a second radiator core body, that is to say, the first radiator core body and the second radiator core body are respectively arranged corresponding to the drive motor and the ISG motor. Then, the first radiator core body and the second radiator core body can work independently, so that compared with starting the entire radiator core body when dissipating heat from one of the drive motor and the ISG motor, the energy consumption of the motor and electronic control heat dissipation structure is reduced.

[0008] In addition, the first radiator core body and the second radiator core body are arranged on the integrated frame, and it can also achieve the effect of facilitating the installation of the motor and electronic control heat dissipation structure, so as to greatly shorten the time required for the staff to install the motor and electronic control heat dissipation structure.

[0009] Optionally, the integrated frame is provided with a wind guide cover. A wind guide cavity is formed between the wind guide cover and the first radiator core body and the second radiator core body. The wind guide cover has an installation position communicated with the wind guide cavity, and the first cooling fan and the second cooling fan are arranged at the installation position.

[0010] By adopting the above technical solution, since both the first cooling fan and the second cooling fan are arranged at the installation position, an air guiding cavity is formed between the air guiding cover, the first radiator core and the second radiator core, thereby improving the cooling efficiency of the first cooling fan and the second cooling fan for the first radiator core and the second radiator core respectively, ensuring the heat dissipation efficiency of the motor electronic control heat dissipation structure for the driving motor and the ISG motor, and at the same time being able to further reduce the energy consumption of the motor electronic control heat dissipation structure.

[0011] Optionally, holding parts are arranged on two opposite sides of the air guiding cover, and a holding space is formed between the holding parts and the air guiding cover.

[0012] By adopting the above technical solution, since a holding space is formed between the holding parts and the air guiding cover, when the staff installs the air guiding cover, they can put their hands into the holding space and hold the holding parts, thereby greatly reducing the installation difficulty of the air guiding cover, improving the installation efficiency of the air guiding cover, and after installing the air guiding cover on the integrated frame, the staff can also hold the holding parts to move the integrated frame, so as to achieve the effect of facilitating the handling of the integrated frame.

[0013] Optionally, it further includes an ATS controller for controlling the first water pump, the second water pump, the first cooling fan and the second cooling fan. The driving motor is provided with a first temperature sensor electrically connected to the ATS controller, and the ISG motor is provided with a second temperature sensor electrically connected to the ATS controller.

[0014] By adopting the above technical solution, when the engineering vehicle is working, the first temperature sensor converts the temperature of the driving motor into a signal and sends it to the ATS controller. When the temperature of the driving motor is higher than the temperature required for the driving motor to cool down, the ATS controller starts the first cooling fan and the first water pump, and then the first water pump pumps the cooling medium in the first radiator core into the cooling channels of the motor controller and the driving motor to achieve heat dissipation for the driving motor; the second temperature sensor converts the temperature of the ISG motor into a signal and sends it to the ATS controller. When the temperature of the ISG motor is higher than the temperature required for the ISG motor to cool down, the ATS controller starts the second cooling fan and the second water pump, and then the second water pump pumps the cooling medium in the second radiator core into the cooling channels of the ISG controller and the ISG motor to achieve heat dissipation for the ISG motor, thereby achieving precise control of the cooling timing of the driving motor and the ISG motor.

[0015] Optionally, the integrated frame is provided with an air guiding cover, and the ATS controller is arranged on the top of the air guiding cover.

[0016] By adopting the above technical solution, since the ATS controller is arranged at the top of the air guide cover, on the one hand, it can enable the heat generated by the ATS controller to be quickly transferred to the air guide cover to reduce the temperature of the ATS controller and avoid the occurrence of high temperature of the ATS controller. On the other hand, it can increase the compactness of the motor and electronic control heat dissipation structure.

[0017] Optionally, both the first water pump and the second water pump are located on the same side of the air guide cover.

[0018] By adopting the above technical solution, since both the first water pump and the second water pump are located on the same side of the air guide cover, the layout of each component of the motor and electronic control heat dissipation structure is more reasonable, thereby further increasing the compactness of the motor and electronic control heat dissipation structure. In addition, it can also make the pipeline connecting the first water pump to the drive motor and the pipeline connecting the second water pump to the ISG motor be located on the same side of the air guide cover, so as to achieve the effect of facilitating the connection of the motor and electronic control heat dissipation structure to the pipeline of the engineering vehicle.

[0019] Optionally, two first water pumps are provided, one of the first water pumps is arranged corresponding to the main drive motor, and the other first water pump is arranged corresponding to the auxiliary drive motor.

[0020] By adopting the above technical solution, since one of the first water pumps is arranged corresponding to the main drive motor and the other first water pump is arranged corresponding to the auxiliary drive motor, that is to say, there are two drive motors, one is the main drive motor and the other is the auxiliary drive motor, and the two first water pumps are respectively arranged corresponding to the main drive motor and the auxiliary drive motor to ensure the heat dissipation effect of the main drive motor and the auxiliary drive motor.

[0021] Optionally, both the first radiator core and the second radiator core have return water pipes, and the two return water pipes are both connected to the same return water main pipe.

[0022] By adopting the above technical solution, since both the first radiator core and the second radiator core have return water pipes, and the two return water pipes are both connected to the same return water main pipe, the number of pipelines is reduced, thereby reducing the production cost of the motor and electronic control heat dissipation structure, and at the same time achieving the effect of facilitating the maintenance of the pipelines.

[0023] Optionally, it further includes an installation frame having an accommodation space, and the integrated frame, the first water pump and the second water pump are all arranged in the accommodation space.

[0024] By adopting the above technical solution, since the first water pump, the second water pump and the integrated frame are all in the accommodation space, the integrated design of the integrated frame with the first water pump and the second water pump is realized, so as to achieve the effect of facilitating the assembly of the motor and electronic control heat dissipation structure, and at the same time it can also achieve the effect of facilitating the maintenance of the motor and electronic control heat dissipation structure.

[0025] Optionally, the installation frame is provided with mounting pieces located in the accommodation space, and the first water pump and the second water pump are fixedly connected to the mounting pieces.

[0026] By adopting the above technical solution, since both the first water pump and the second water pump are fixedly connected to the mounting pieces, and the mounting pieces are arranged on the installation frame, the connection stability between the first water pump and the second water pump and the installation frame is increased, thereby avoiding the situation that the vibration of the engineering vehicle affects the service life of the first water pump and the second water pump.

[0027] Due to the adoption of the above technical solution, the beneficial effects obtained by this application are as follows:

The second water pump is used to connect the second radiator core, the ISG controller, and the ISG motor, so that the cooling medium in the second radiator core enters the cooling channels of the ISG controller and the ISG controller through the second water pump to dissipate heat from the ISG controller and the ISG motor. That is to say, the first radiator core and the second radiator core are respectively arranged corresponding to the drive motor and the ISG motor, and then the first radiator core and the second radiator core can work independently. Therefore, compared with starting the entire radiator core when dissipating heat from one of the drive motor and the ISG motor, the energy consumption of the motor and electronic control heat dissipation structure is reduced.

[0041] Refer to Figure 1 and Figure 2 , a motor and electronic control heat dissipation structure for a new energy engineering vehicle is disclosed, which includes an integrated frame 1, a first radiator core 2 arranged on the integrated frame 1, a second radiator core 3 arranged on the integrated frame 1, a first water pump 4, and a second water pump 5. A first cooling fan 21 is arranged on one side of the first radiator core 2, and a second cooling fan 31 is arranged on one side of the second radiator core 3. The first water pump 4 is used to connect the cooling channels of the first radiator core 2, the motor controller, and the drive motor, so that the cooling medium in the first radiator core 2 enters the cooling channels of the motor controller and the drive motor through the first water pump 4 to dissipate heat from the motor controller and the drive motor. The second water pump 5 is used to connect the cooling channels of the second radiator core 3, the ISG controller, and the ISG motor, so that the cooling medium in the second radiator core 3 enters the cooling channels of the ISG controller and the ISG controller through the second water pump 5 to dissipate heat from the ISG controller and the ISG motor.

[0042] When dissipating heat from the drive motor of a new energy engineering vehicle, the first water pump 4 and the first cooling fan 21 are started. Subsequently, the first cooling fan 21 dissipates heat from the first radiator core 2. The first water pump 4 pumps the cooling medium in the first radiator core 2 into the cooling channels of the motor controller and the drive motor, thereby achieving heat dissipation for the drive motor and the motor controller. When dissipating heat from the ISG motor, the second water pump 5 and the second cooling fan 31 are started. Subsequently, the second cooling fan 31 dissipates heat from the second radiator core 3. The second water pump 5 pumps the cooling medium in the second radiator core 3 into the cooling channels of the ISG controller and the ISG motor to achieve heat dissipation for the ISG controller and the ISG motor. Since the motor and electronic control heat dissipation structure in this application includes the first radiator core 2 and the second radiator core 3.

[0043] It can be understood that the first radiator core 2 and the second radiator core 3 are respectively arranged corresponding to the drive motor and the ISG motor. Subsequently, the first radiator core 2 and the second radiator core 3 can work independently. Thus, compared with starting the entire radiator core when dissipating heat from one of the drive motor and the ISG motor, the energy consumption of the motor and electronic control heat dissipation structure is reduced.

[0044] In addition, the first radiator core 2 and the second radiator core 3 are arranged in the integrated frame 1, which can also achieve the effect of facilitating the installation of the motor and electronic control heat dissipation structure, thereby greatly shortening the time required for the staff to install the motor and electronic control heat dissipation structure.

[0045] This application does not specifically limit the installation method of the first cooling fan 21 and the second cooling fan 31. Preferably, referring to Figure 2 , the integrated frame 1 is provided with a wind guide cover 11. A wind guide cavity is formed between the wind guide cover 11 and the first radiator core 2 and the second radiator core 3. The wind guide cover 11 has an installation position communicating with the wind guide cavity, and the first cooling fan 21 and the second cooling fan 31 are arranged at the installation position.

[0046] It can be understood that the wind guide cover 11 has multiple installation positions, and the number of installation positions is equal to the total number of the first cooling fan 21 and the second cooling fan 31. The first cooling fan 21 and the second cooling fan 31 are respectively installed at the multiple installation positions.

[0047] Since both the first cooling fan 21 and the second cooling fan 31 are arranged at the installation position, a wind guide cavity is formed between the wind guide cover 11 and the first radiator core 2 and the second radiator core 3. Subsequently, the cooling efficiency of the first cooling fan 21 and the second cooling fan 31 for the first radiator core 2 and the second radiator core 3 respectively is improved, so as to ensure the heat dissipation efficiency of the motor and electronic control heat dissipation structure for the drive motor and the ISG motor, and at the same time, the energy consumption of the motor and electronic control heat dissipation structure can be further reduced.

[0048] Further, referring to Figure 2 , holding parts are arranged on two opposite sides of the air guide cover 11. A holding space is formed between the holding parts and the air guide cover 11. Then, when the staff installs the air guide cover 11, the hand can be inserted into the holding space and hold the holding parts, so as to greatly reduce the installation difficulty of the air guide cover 11, thereby improving the installation efficiency of the air guide cover 11. At the same time, after the air guide cover 11 is installed on the integrated frame 1, the staff can also hold the holding parts to move the integrated frame 1, so as to achieve the effect of facilitating the handling of the integrated frame 1.

[0049] Preferably, the holding part is a rod-shaped structure in a C shape. Both ends of the holding part are fixedly connected to the air guide cover 11, so that the holding part and the air guide cover 11 jointly form a holding space.

[0051] In a preferred embodiment, referring to Figure 2 , the motor and electronic control heat dissipation structure further includes an ATS controller 6 for controlling the first water pump 4, the second water pump 5, the first cooling fan 21 and the second cooling fan 31. The drive motor is provided with a first temperature sensor electrically connected to the ATS controller 6, and the ISG motor is provided with a second temperature sensor electrically connected to the ATS controller 6.

[0052] Specifically, when the engineering vehicle is working, the first temperature sensor converts the temperature of the drive motor into a signal and sends it to the ATS controller 6. When the temperature of the drive motor is higher than the temperature required for cooling the drive motor, the ATS controller 6 starts the first cooling fan 21 and the first water pump 4. Then, the first water pump 4 pumps the cooling medium in the first radiator core 2 into the cooling channels of the motor controller and the drive motor to achieve heat dissipation of the drive motor. The second temperature sensor converts the temperature of the ISG motor into a signal and sends it to the ATS controller 6. When the temperature of the ISG motor is higher than the temperature required for cooling the ISG motor, the ATS controller 6 starts the second cooling fan 31 and the second water pump 5. Then, the second water pump 5 pumps the cooling medium in the second radiator core 3 into the cooling channels of the ISG controller and the ISG motor to achieve heat dissipation of the ISG motor, thereby realizing precise control of the cooling timing of the drive motor and the ISG motor.

[0053] It should be noted that the electrical connection between the first temperature sensor and the ATS controller 6 and the electrical connection between the second temperature sensor and the ATS controller 6 can be electrically connected through a transmission line, and can also be signal-connected in a wireless manner.

[0054] In a preferred embodiment, referring to Figure 2 , the integrated frame 1 is provided with an air guide cover 11, and the ATS controller 6 is arranged on the top of the air guide cover 11. On the one hand, it can enable the heat generated by the ATS controller 6 to be quickly transferred to the air guide cover 11 to reduce the temperature of the ATS controller 6 and avoid the occurrence of high temperature of the ATS controller 6. On the other hand, it can increase the compactness of the motor and electronic control heat dissipation structure.

[0055] Furthermore, referring to Figure 2 , both the first water pump 4 and the second water pump 5 are located on the same side of the air guide cover 11, thus making the layout of each component of the motor and electronic control heat dissipation structure more reasonable to further increase the compactness of the motor and electronic control heat dissipation structure; in addition, it can also make the pipeline connecting the first water pump 4 and the drive motor and the pipeline connecting the second water pump 5 and the ISG motor located on the same side of the air guide cover 11, so as to achieve the effect of facilitating the connection of the motor and electronic control heat dissipation structure and the pipeline of the engineering vehicle.

[0058] In other embodiments, only one first water pump 4 can also be provided to use one first water pump 4 to dissipate heat from the main drive motor and the auxiliary drive motor.

[0059] In a preferred embodiment, referring to Figure 1 , the volume of the core of the first radiator 2 is larger than the volume of the core of the second radiator 3 to ensure the heat dissipation efficiency of the drive motor.

[0060] Preferably, at least two first cooling fans 21 are provided to improve the cooling effect on the core of the first radiator 2.

[0061] In a preferred embodiment, referring to Figure 2 , both the core of the first radiator 2 and the core of the second radiator 3 have return water pipes, and the two return water pipes are both connected to the same return water main pipe, thus reducing the number of pipelines to reduce the production cost of the motor and electronic control heat dissipation structure and achieving the effect of facilitating the maintenance of the pipelines at the same time.

[0062] In a preferred embodiment, referring to Figure 1 and Figure 2, the motor and electronic control heat dissipation structure further includes an installation frame with an accommodation space. The integrated frame 1, the first water pump 4, and the second water pump 5 are all arranged in the accommodation space, thus realizing the integrated design of the integrated frame 1 with the first water pump 4 and the second water pump 5, so as to achieve the effect of facilitating the assembly of the motor and electronic control heat dissipation structure, and at the same time, it can also achieve the effect of facilitating the maintenance of the motor and electronic control heat dissipation structure.

[0063] Further, the installation frame is provided with installation pieces located in the accommodation space, and the first water pump 4 and the second water pump 5 are fixedly connected to the installation pieces.

[0064] Specifically, the installation pieces protrude upward, so as to form a space for accommodating the first water pump 4 and the second water pump 5 between the installation pieces and the installation frame. The first water pump 4 and the second water pump 5 are both fixedly connected to the bottom of the installation pieces, so as to increase the connection stability between the first water pump 4 and the second water pump 5 and the installation frame, thereby avoiding the situation that the service life of the first water pump 4 and the second water pump 5 is affected by the vibration of the engineering vehicle.
