Description

[0002] With the needs of social modernization, the power consumption of field operation equipment is increasing, and the demand for the system power of on-vehicle power generation systems is also increasing day by day. General on-vehicle power take-off power generation devices cannot meet the 100-kilowatt power consumption demand of field operation equipment because their output power is only dozens of kilowatts.

[0003] To meet the 100-kilowatt power consumption demand, a generator with a higher power (such as 200 KW) needs to be installed on the vehicle. However, the loading space on the vehicle is limited, and the heat generated by the high-power generator is high, and a heat dissipation system also needs to be set up, resulting in insufficient loading space on the vehicle, or the overall vehicle volume is too large and inconvenient to use.

[0004] Therefore, designing an on-vehicle power take-off power generation system and a power take-off power generation vehicle that can arrange each component reasonably, have a relatively small overall volume, be applicable to field operations, and have good heat dissipation effect and can meet the demand for high-power power take-off power generation is a technical problem that urgently needs to be solved at present.

[0040] In addition, if terms such as "first", "second", etc. are used only for distinguishing descriptions, they cannot be understood as indicating or implying relative importance.

[0041] It should be noted that, without conflict, the features in the embodiments of the present invention can be combined with each other.

[0042] To meet the demand for power take-off power generation in the wild with high power (for example, 200KW), this embodiment provides a vehicle-mounted power take-off power generation system 100 with heat dissipation, which can make the layout of each component reasonable, the overall volume is small, it can be applied to field operations, and has good heat dissipation effect, and can meet the demand for high-power power take-off power generation.

[0043] Please refer to Figures 1 to 3 , the vehicle-mounted power take-off power generation system 100 with heat dissipation provided in this embodiment includes a vehicle chassis 110, an engine (not shown in the figure), a gearbox (not shown in the figure), a drive shaft 120, a water-cooled generator 130, a water-cooled power converter 140, and a radiator 150.

[0044] Please refer to Figure 2 and Figure 3, the transmission, the drive shaft 120, the water-cooled generator 130, and the water-cooled power converter 140 are arranged in sequence along the length direction of the vehicle chassis 110. One end of the drive shaft 120 is in driving connection with the water-cooled generator 130. Among them, the power of the water-cooled generator 130 can be selected as 200KW. The transmission is installed on the vehicle chassis 110, and the other end of the drive shaft 120 is in driving connection with the power take-off port of the transmission. Here, the transmission can also be a transfer case, and the drive shaft 120 can be a coupling. The engine is installed on the vehicle chassis 110, and the engine drives the transmission. The water-cooled generator 130 is installed on the vehicle chassis 110, and the water-cooled power converter 140 is installed on the vehicle chassis 110 and is connected to the water-cooled generator 130 through a cable. The water-cooled power converter 140 is used to supply power to the electrical equipment.

[0045] Both of the two radiators 150 are installed on the vehicle chassis 110. The two radiators 150 are arranged below the water-cooled power converter 140. The length direction of the two radiators 150 is parallel to the length direction of the vehicle chassis 110. The two radiators 150 are connected to the water-cooled generator 130 and the water-cooled power converter 140 through water pipes 160, which can improve the heat dissipation effect of the water-cooled generator 130 and the water-cooled power converter 140, create a basis for ensuring the high output power of the system, and also create conditions for using a high-power (such as 200KW) water-cooled generator 130. Setting two radiators 150 can not only meet the requirements of heat dissipation efficiency, but also, compared with using a single radiator, enable the two radiators 150 adopted to have a smaller volume design, which is convenient for flexible arrangement on the vehicle chassis 110, avoiding the radiator occupying too much space and being difficult to install on the vehicle chassis 110, so that each component is reasonably arranged and the overall volume is small, and it can be applied to field operations.

[0046] In this embodiment, considering that the volume of the water-cooled power converter 140 is small and the space below the water-cooled power converter 140 is large, two radiators 150 are designed to be installed below the water-cooled power converter 140. In other embodiments, it can also be considered to install the radiator 150 below, above or on the side of other components, as long as the overall volume requirements can be met, avoiding the radiator occupying too much space, so that each component is reasonably arranged and the overall volume is small, and it can be applied to field operations.

[0047] In this embodiment, the number of the radiating water tanks 150 is two, so that the volume of a single radiating water tank 150 is small, facilitating flexible arrangement on the vehicle chassis 110. In other embodiments, the number of the radiating water tanks 150 may also be three, and the volume of a single radiating water tank 150 can be designed to be smaller, making full use of the remaining space on the vehicle chassis 110. Meanwhile, the heat dissipation requirements of the main components are met, so as to increase the power of the system within a limited installation space, reduce losses, and improve the efficiency of power take-off power generation.

[0048] Specifically, please refer to Figure 3 and Figure 5 . Pipes communicating with the water pipe 160 are wound on the surfaces of the water-cooled generator 130 and the water-cooled power converter 140. The pipes are used to dissipate the heat generated by the devices. The two radiating water tanks 150, the water-cooled generator 130, and the water-cooled power converter 140 are sequentially connected through the water pipe 160 to form a circulating water path. Among them, the water pipe 160 is preferably a flexible pipe, which can withstand a large degree of deformation, facilitating bending and wiring. After first meeting the installation requirements of the water-cooled generator 130, the water-cooled power converter 140, and the two radiating water tanks 150, then connecting the water pipe 160 will not affect the layout positions of the main components, reduce the assembly difficulty, and at the same time meet the requirements of the main high-power power take-off power generation and high-efficiency heat dissipation. Both the generator and the power converter adopt water-cooled type, and the two radiating water tanks 150 are connected in series, so as to increase the power of the system within a limited installation space, reduce losses, and improve the efficiency of power take-off power generation.

[0049] The radiating water tank 150 includes heat exchange pipes and a radiator fan. Among them, the heat exchange pipes are communicated with the external water pipe 160, and the heat exchange pipes are made of materials with high heat conduction efficiency. The radiator fan is used to blow air to accelerate the air to take away the heat dissipated by the heat exchange pipes, realizing the cooling of the cooling water in the heat exchange pipes, so as to reduce the temperature of the cooling water flowing out of the radiating water tank 150, and thus circularly cool the water-cooled generator 130 and the water-cooled power converter 140. In this embodiment, the two radiating water tanks 150 are connected in series, so that the cooling water is cooled twice in one cycle, which can ensure that the temperature of the cooling water flowing to the water-cooled generator 130 and the water-cooled power converter 140 is relatively low, and ensure the cooling effect on the water-cooled generator 130 and the water-cooled power converter 140.

[0050] The working principle of the vehicle-mounted power take-off power generation system 100 with heat dissipation provided in this embodiment:

[0051] The engine of the system drives the transmission, which drives the drive shaft 120 to rotate. The drive shaft 120 drives the water-cooled generator 130 to generate electricity. The electricity generated by the water-cooled generator 130 is supplied to electrical equipment after being converted by the water-cooled power converter 140. During the operation of the water-cooled generator 130 and the water-cooled power converter 140, two radiators 150 drive the cooling water to flow in the water pipe 160, continuously dissipating heat from the water-cooled generator 130 and the water-cooled power converter 140, increasing the output power of the system under the same volume of the system, and increasing the power of the system within a limited space.

[0052] Please refer to Figure 4 , the vehicle-mounted power take-off power generation system 100 with heat dissipation further includes a bracket 170, which is installed on the vehicle chassis 110. The water-cooled power converter 140 is installed on the vehicle chassis 110 through the bracket 170. The bracket 170 can raise the height of the water-cooled power converter 140, making the space below the water-cooled power converter 140 larger. The two radiators 150 are located below the bracket 170 and are connected to the vehicle chassis 110, which can make the system structure compact and keep the overall volume at a relatively small level.

[0053] To further make the structure compact, the two radiators 150 are arranged along the width direction of the vehicle chassis 110, and the length direction of the two radiators 150 is parallel to the length direction of the vehicle chassis 110.

[0054] To further keep the overall height of the system at a relatively small level, the two radiators 150 are inclined relative to the bottom surface of the water-cooled power converter 140. Preferably, the two radiators 150 are arranged in a V shape. In this way, not only can the water tanks be flexibly arranged on the vehicle chassis 110 to avoid excessive space occupation by the water tanks, but also the heat dissipation of the water tanks can be increased.

[0055] In this embodiment, the two radiators 150 are arranged in a V shape. Here, the V shape can be an upright V shape or an inverted V shape. In other embodiments, the two radiators 150 can also be inclined in the same direction, that is, the two radiators 150 are arranged in parallel. In this way, the space occupied by the two radiators 150 will not increase either.

[0056] This embodiment also provides a power take-off power generation vehicle, which includes the vehicle-mounted power take-off power generation system 100 with heat dissipation.

[0057] The beneficial effects of the vehicle-mounted power take-off power generation system 100 with heat dissipation and the power take-off power generation vehicle provided in this embodiment include:

[0058] 1. A radiator 150 is also arranged on the vehicle chassis 110, and the radiator 150 is connected to the water-cooled generator 130 and the water-cooled power converter 140, which can improve the heat dissipation effect of the water-cooled generator 130 and the water-cooled power converter 140, create a basis for ensuring the high output power of the system, and also create conditions for using a high-power (such as 200KW) water-cooled generator 130;

[0059] 2. Two radiators 150 are provided, which can not only meet the requirements of heat dissipation efficiency, but also, compared with using a single radiator, enable the two radiators 150 used to have a smaller volume design, facilitate flexible arrangement on the vehicle chassis 110, avoid the radiator occupying too much space and being difficult to install on the vehicle chassis 110, so that each component is reasonably arranged and the overall volume is small, and it can be applied to field operations;

[0060] 3. Both the generator and the power converter are water-cooled, and the two radiators 150 are connected in series, so as to meet the requirement of increasing the power of the system within a limited installation space, reduce losses, and improve the efficiency of power take-off power generation.

Any change or replacement that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention.
