[0024] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0025] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movements between components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0026] The embodiments of this application will now be described in detail. In this embodiment, the front-back direction refers to the direction of vehicle travel and the direction of vehicle reversing, respectively; the left-right direction refers to the width direction of the vehicle body; and the up-down direction refers to the height direction of the vehicle body.

[0027] With the rapid development of new energy vehicles, the demand for power generation is constantly increasing, and the displacement of range extenders is also gradually increasing. To achieve twice the power generation, the displacement needs to be increased by three times or even more, leading to increased costs and fuel consumption.

[0028] To address this issue, two small-displacement range extenders are typically mounted on a single vehicle to replace a large-displacement range extender. This requires two range extender cooling systems and one drive motor cooling system. However, these three cooling systems cannot be simultaneously mounted at the front of the chassis; two cooling modules must be side-mounted, resulting in insufficient frontal area, poor heat dissipation, and numerous mounting brackets that occupy significant space, hindering the vehicle's lightweight design.

[0029] To address the aforementioned shortcomings, such as Figure 1 and Figure 2 As shown, this application provides a multi-power cooling module, including an engine radiator 10, an intercooler 20, an electric drive radiator 30, several electric fans 40, a support frame 50, and a fan shield 60. The engine radiator 10 and intercooler 20 are used to cool the vehicle's range extender, and the electric drive radiator 30 is used to cool the vehicle's drive motor 90. The engine radiator 10, intercooler 20, electric drive radiator 30, electric fans 40, and fan shield 60 are all integrated onto the support frame 50. The intercooler 20 and electric drive radiator 30 are located on the front side of the engine radiator 10, and the several electric fans 40 are located on the rear side of the engine radiator 10.

[0030] The engine radiator 10 includes a first engine radiator 11 and a second engine radiator 12, which respectively cool the two range extenders of the vehicle. Figure 2 As shown, on a plane perpendicular to the front-to-back direction, the first engine radiator 11 and the second engine radiator 12 are arranged side by side and close to each other.

[0031] The intercooler 20 includes a first intercooler 21 and a second intercooler 22, which are used to dissipate heat from the two range extenders of the vehicle. On a plane perpendicular to the front-rear direction, the first intercooler 21, the second intercooler 22 and the electric drive radiator 30 are arranged side by side, with the electric drive radiator 30 located between the first intercooler 21 and the second intercooler 22.

[0032] The first engine radiator 11 and the second engine radiator 12 are arranged along a first direction, as are the first intercooler 21, the second intercooler 22, and the electric drive radiator 30. In this embodiment, the first direction is vertical. The first engine radiator 11 is located above the second engine radiator 12, and the first intercooler 21 and the second intercooler 22 are located on the upper and lower sides of the electric drive radiator 30, respectively. In some cases, the first direction may also be horizontal.

[0033] By arranging the first engine radiator 11, the second engine radiator 12, the first intercooler 21, the second intercooler 22, and the electric drive radiator 30 in the same direction, the different heat dissipation components can be aligned as much as possible in the front-to-back direction, making the overall structure of the multi-power cooling module of this application more compact and occupying less space.

[0034] Furthermore, the first intercooler 21 is located in front of the first engine radiator 11, and their cores at least partially overlap, allowing the airflow from the electric fan 40 to quickly pass through the first engine radiator 11 and the first intercooler 21 in the same direction. The second intercooler 22 is located in front of the second engine radiator 12, and their cores at least partially overlap, allowing the airflow from the electric fan 40 to quickly pass through the second engine radiator 12 and the second intercooler 22 in the same direction, which helps to improve airflow utilization efficiency and enhance heat dissipation.

[0035] like Figure 3 As shown, in this embodiment, the electronic fans 40 are configured as three groups. The three groups of electronic fans 40 are arranged in a vertical direction, and from top to bottom, they are the first group of electronic fans 41, the second group of electronic fans 42, and the third group of electronic fans 43.

[0036] The first set of electric fans 41 is located behind the first engine radiator 11, and the third set of electric fans 43 is located behind the second engine radiator 12. The second set of electric fans 42 is located between the first set of electric fans 41 and the third set of electric fans 43, with its upper half located behind the first engine radiator 11 and its lower half located behind the second engine radiator 12. Thus, the first set of electric fans 41 and the second set of electric fans 42 can dissipate heat for the first engine radiator 11, the first intercooler 21, and the electric drive radiator 30, while the second set of electric fans 42 and the third set of electric fans 43 can dissipate heat for the second engine radiator 12, the second intercooler 22, and the electric drive radiator 30.

[0037] Each electric fan 40 can be individually controlled to turn on or off, achieving more precise control and reducing energy consumption. In this embodiment, the first group of electric fans 41 and the second group of electric fans 42 are turned on when the first engine radiator 11 is working, and the third group of electric fans 43 and the second group of electric fans 42 are turned on when the second engine radiator 12 is working. When both the first engine radiator 11 and the second engine radiator 12 are working, all three groups of electric fans 40 are turned on simultaneously. In some cases, the on / off status of each electric fan 40 can also be flexibly set according to different needs.

[0038] In this embodiment, there are five electronic fans 40. Specifically, the first group of electronic fans 41 includes two electronic fans 40, the second group of electronic fans 42 includes one electronic fan 40, and the third group of electronic fans 43 includes two electronic fans 40.

[0039] In traditional cooling systems, each range extender and drive motor requires two to three electric fans. However, the number of control pins is insufficient to individually control all the electric fans, and controlling multiple electric fans with the same pin can easily lead to fan stalling. In this embodiment, only five electric fans 40 are needed to provide cooling for the two range extenders and drive motor 90. Each electric fan 40 can be configured with an independent pin for individual control, allowing for flexible start-stop based on actual operating conditions. This configuration meets the cooling requirements under different operating conditions, and the independent pin control eliminates the control malfunctions caused by multiple fans sharing a pin, effectively improving system stability.

[0040] The support frame 50 is rectangular. The first engine radiator 11 and the second engine radiator 12 are both located within and fixed to the support frame 50. The first intercooler 21, the second intercooler 22, and the electric drive radiator 30 are all fixed to the support frame 50. Specifically, as... Figure 2 As shown, the intercooler 20 is provided with a first fixing leg 23, which is fixed to the support frame 50 by fasteners. Both the first intercooler 21 and the second intercooler 22 are provided with four first fixing legs 23, distributed at the four corners of the first intercooler 21 and the second intercooler 22, located on the side closest to the support frame 50. The electric drive radiator 30 is provided with two fixing legs 31, which are fixed to the support frame 50 by fasteners. There are four second fixing legs 31.

[0041] The support frame 50 is provided with two mounting parts 51, which are symmetrically arranged on both sides of the support frame 50. The mounting parts 51 are fixed to the vehicle frame, thus fixing the multi-power cooling module as a whole to the frame.

[0042] A wind shield 60 is arranged around a plurality of electric fans 40 and is fixed to a support frame 50. The electric fans 40 are fixed to the wind shield 60, thereby securing the electric fans 40 to the support frame 50.

[0043] Please refer to the following at the same time Figure 4 This application also provides a multi-power cooling system, including a first range extender 70, a second range extender 80, a drive motor 90, and the multi-power cooling module as described above.

[0044] The first range extender 70 is connected to the first engine radiator 11 via a first cooling circuit 71 and to the first intercooler 21 via a first intercooler circuit 72. The first engine radiator 11 and the first intercooler 21 can cool the first range extender 70. The second range extender 80 is connected to the second engine radiator 12 via a second cooling circuit 81 and to the second intercooler 22 via a second intercooler circuit 82. The second engine radiator 12 and the second intercooler 22 can cool the second range extender 80. The drive motor 90 is connected to the electric drive radiator 30 via an electric drive cooling circuit 91. The electric drive radiator 30 can cool the drive motor 90. The first cooling circuit 71, the first intercooler circuit 72, the second cooling circuit 81, the second intercooler circuit 82, and the electric drive cooling circuit 91 circulate independently.

[0045] This application also provides a vehicle, including a frame and the multi-power cooling system as described above. The multi-power cooling module is disposed at the front end of the frame, so that the cooling devices for the first range extender 70, the second range extender 80, and the drive motor 90 can be compactly integrated at the front end of the frame, providing a better airflow surface and improving heat dissipation.

[0046] The multi-power cooling module, system, and vehicle of this application integrate a first engine radiator 11, a second engine radiator 12, an intercooler 20 for cooling two range extenders, and an electric drive radiator 30 for cooling the drive motor 90. The first engine radiator 11 and the second engine radiator 12 are arranged side by side, and the electric fan 40 is located on the rear side of the engine radiator 10. This allows the multi-power cooling module to be compactly arranged at the front of the vehicle frame, improving the heat dissipation effect while reducing the space occupied. This is beneficial for reducing costs, achieving lightweight design of the whole vehicle, and improving assembly efficiency.

The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
