[0023] In the description of the present invention, it should be noted that, unless otherwise clearly stipulated and limited, the terms "set", "installed", "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection; it can be directly connected or indirectly connected through an intermediate medium; for ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] If there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features.

[0025] An intelligent power unit cabin according to an embodiment of the present invention is Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, it includes a cabin, a power unit radiator assembly arranged in the cabin, a first air intake grille 7, and a baffle 13. The power unit radiator assembly includes an intercooler 12, a generator radiator 14, and an engine radiator 15. The cabin includes a frame and a skin. The skin is connected to the frame. The frame is used to carry components such as the engine, the generator, and the fuel tank. The first air intake grille 7 is arranged on the skin at a position corresponding to the power unit radiator assembly. The baffle 13 is arranged between the first air intake grille 7 and the radiator assembly. Specifically, during use, the intelligent power unit is symmetrically screwed to both sides of the special vehicle chassis. Since the first air intake grille 7 is provided at a position on the skin corresponding to the power unit radiator, the cooling air can easily enter the cabin, thereby effectively reducing the inlet temperature of the cooling air of the power unit radiator. At the same time, since a baffle 13 is installed between the first air intake grille 7 and the power unit radiator assembly, the high-temperature air discharged from the power unit radiator is prevented from flowing back, ensuring that the cooling air inhaled by the power unit radiator is at ambient temperature, effectively improving the heat dissipation performance of the power unit radiator, reducing the temperature of the intelligent power unit cabin, and facilitating the intelligent power unit cabin to realize the infrared stealth function, which is suitable for multi-axis electric drive special vehicles.

[0026] Furthermore, the first air intake grille 7 is tilted, with an inclination of 45°.

[0027] Furthermore, the power unit radiator assembly also includes a high-pressure cooling fan 16 and a high-pressure cooling fan motor driver 6 connected to the high-pressure cooling fan 16. The high-pressure cooling fan motor driver 6 is arranged on the outer side wall of the cabin skin. The high-pressure cooling fan motor driver 6 controls the high-pressure fan motor 17. A second air intake grille hole 5 is provided at a position on the skin corresponding to the high-pressure cooling fan motor driver 6. The second air intake grille hole 5 is square. Since the second air intake grille hole 5 is provided at a position on the skin corresponding to the high-pressure cooling fan motor driver 6, it is convenient for cooling air at ambient temperature to enter the cabin under the suction of the high-pressure cooling fan 16 to be cooled in a direct air cooling manner, thereby improving the cooling effect of the high-pressure cooling fan motor driver 6.

[0028] Furthermore, the power unit radiator assembly also includes two groups of low-pressure forced exhaust fans 1, and the positions on the skin corresponding to the two groups of low-pressure forced exhaust fans 1 are provided with third air intake grille holes 9, and the third air intake grille holes 9 are square. Since the power unit radiator assembly also includes two groups of low-pressure forced exhaust fans 1, and the positions on the skin corresponding to the two groups of low-pressure forced exhaust fans 1 are provided with third air intake grille holes 9, the air flow inside and outside the cabin can be strengthened, the air temperature inside the cabin can be reduced, and the high temperature accumulation phenomenon inside the power unit when working in a high-temperature environment can be prevented, especially the position where the electrical components are installed, and the working environment of the various components of the power unit is optimized. The setting of the third air intake grille holes 9 increases the cooling air intake volume and further reduces the air temperature inside the cabin.

[0029] Furthermore, the power unit radiator assembly also includes two low-pressure fan air guide covers 2, and the two groups of low-pressure forced exhaust fans 1 are respectively connected to a low-pressure fan air guide cover 2, thereby optimizing the heat dissipation cooling air intake volume of the two groups of low-pressure forced exhaust fans 1 and effectively reducing the air temperature in the cabin.

[0030] Furthermore, a fourth air intake grille hole 10 is provided on the skin, and the fourth air intake grille hole 10 is arranged close to the engine to reduce the intake temperature of the engine and improve the reliability of the engine.

[0031] Furthermore, it also includes an air filter air guide cover 19, which is connected to the engine. The setting of the air filter air guide cover 19 effectively prevents the high-temperature air in the cabin from flowing into the air filter 18, reduces the engine intake temperature, and further improves the engine reliability.

[0032] Furthermore, exhaust grille holes are respectively provided on the top skin 21 and the bottom skin 8 of the cabin body to facilitate the entry of outside air into the cabin body and improve the fluidity of the air in the cabin body.

[0033] Furthermore, exhaust grille holes are provided on the front skin 4 and the rear skin of the cabin, which not only ensure the air circulation in the cabin, but also prevent the tires of vehicles arranged in front and behind the power unit from throwing mud and water into the cabin.

[0034] During the operation of the power unit in the intelligent power unit cabin of the present invention, cooling air flows into the cabin under the suction of the high-pressure cooling fan 16, part of the high-temperature air is discharged through the exhaust grille holes on the front skin 4, and part of the high-temperature air is discharged through the exhaust grille holes on the top skin 21 and the bottom skin 8; low-temperature air is sucked into the cabin by the low-pressure forced exhaust fan 1, and merges with the high-temperature air discharged by the high-pressure cooling fan 16, thereby improving the working environment temperature of ECU22, IPU23 and generator controller 24, and is discharged through the exhaust grille holes on the rear, top and bottom of the power unit, thereby effectively reducing the infrared characteristics of the overall outer side of the power unit.

[0035] Although the disclosure is disclosed as above, the protection scope of the disclosure is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the disclosure, and these changes and modifications will fall within the protection scope of the present invention.
