[0043] In addition, the protective cover 2 is provided with a filling port 231 corresponding to the tank cover of the water tank, so that when the water tank is replenished with coolant, the tank cover of the water tank can be operated through the filling port 231 to achieve the effect of facilitating the replenishment of coolant to the water tank.

[0045] The present application does not specifically limit the formation method of the heat dissipation area. Preferably, refer to Figure 1 and Figure 2 The protective cover 2 is provided with a plurality of heat dissipation holes 221 corresponding to the radiator. The plurality of heat dissipation holes 221 form a heat dissipation zone, so that when the thermal management system is working, the heat generated by the radiator is quickly discharged through the heat dissipation holes 221.

[0046] In other embodiments, the protective cover 2 is provided with a heat dissipation gap, and the heat dissipation gap forms a heat dissipation area to increase the heat dissipation efficiency of the radiator.

[0047] Better, refer to Figure 1 and Figure 2 The protective cover 2 has heat dissipation areas on both opposite sides, so that when the radiator is dissipating heat, the heat dissipation area on one side is used to allow cold air to enter, and the heat dissipation area on the other side is used to discharge hot air, thereby improving the heat dissipation efficiency of the radiator.

[0048] In a preferred embodiment, referring to Figure 1 The compressor is provided with a replenishing port, and the protective cover 2 is provided with an avoidance port 222 corresponding to the replenishing port.

[0049] Specifically, the compressor has a replenishing pipe for replenishing refrigerant, and the pipe mouth of the replenishing pipe forms a replenishing port. When replenishing refrigerant to the compressor, the filling pipe of the refrigerant filling equipment can be connected to the replenishing port via the avoidance port 222 to facilitate the replenishment of refrigerant to the compressor, thereby facilitating the maintenance of the thermal management system.

[0050] In a preferred embodiment, referring to Figure 1 The replenishing port is arranged toward the top of the protective cover 2, and the frame 1 is provided with a dust cover 11 located at the top of the replenishing port. The dust cover 11 is spaced apart from the replenishing port so that an operating space is formed between the dust cover 11 and the replenishing port.

[0051] It can be understood that the replenishing pipe is extended upward in the vertical direction, so that the replenishing port is toward the top of the protective cover 2, so as to facilitate the replenishment of refrigerant to the compressor; because the frame 1 is provided with a dust cover 11 located on the top of the replenishing port, the dust cover 11 can protect the replenishing port, so as to achieve the effect of protecting the replenishing port, so as to avoid the replenishing port from being deformed by gravel or other particles, so as to ensure that the compressor can be normally replenished with refrigerant; because an operating space is formed between the dust cover 11 and the replenishing port, it is not necessary to remove the dust cover 11 when replenishing the refrigerant to the compressor, so as to facilitate the replenishment of refrigerant to the compressor.

[0052] It should be noted that the dust cover 11 can not only be arranged on the frame 1 , but also be arranged on the protective cover 2 and formed by partially bending the protective cover 2 .

[0056] Since the second side panel 22 is detachably connected to the frame 1, the second side panel 22 can be removed from the frame 1 when the thermal management system is inspected and repaired, so as to facilitate the inspection and repair of the thermal management system; since the second side panel 22 is provided with an operating port 224 located in the heat dissipation area, on the one hand, the operating port 224 can increase the heat dissipation effect of the radiator, and on the other hand, the setting of the operating port 224 can also facilitate the staff to remove the second side panel 22 from the frame 1.

[0057] Furthermore, the bottom of the second side plate 22 is open so that the pipeline inside the protective cover 2 can extend through the bottom of the second side plate 22 .

[0058] Since the bottom of the second side plate 22 is open, the pipes inside the protective cover 2 can extend through the bottom of the second side plate 22, thereby facilitating the connection of the pipes of the thermal management system with other pipes on the engineering vehicle, while also improving the heat dissipation effect of the radiator.

[0059] Further, see Figure 2 The protective cover 2 also includes a third side plate 24 arranged opposite to the first side plate 21 and a fourth side plate 25 arranged opposite to the second side plate 22.

[0060] Preferably, the fourth side plate 25 is also provided with a heat dissipation area to further improve the heat dissipation efficiency of the radiator.

[0061] In a preferred embodiment, referring to Figure 1 and Figure 2 The water tank is arranged on the top of the frame 1, and the protective cover 2 also has a top cover 23 arranged on the top of the frame 1. The top cover 23 is protruded in the direction away from the frame 1 to cover the outside of the water tank. The filling port 231 is arranged on the top cover 23, so that the water tank and the structure located inside the frame 1 are avoided, so that the structural layout in the frame 1 is more reasonable, and at the same time, the effect of facilitating the installation of the water tank can be achieved.

[0062] Further, see Figure 2 A liquid sight glass is provided on the side of the water tank, and an observation port 232 is provided on the top cover 23 corresponding to the liquid sight glass, so that the staff can observe the remaining amount of coolant in the water tank through the observation port 232 and the liquid sight glass.

[0064] It should be noted that the thermal management system has a controller, and the forced start switch is electrically connected to the controller of the thermal management system so that the forced start switch can control the controller to control the forced start of the thermal management system.

[0065] Furthermore, the protective cover 2 is provided with a safety cover, which is movably connected to the protective cover 2 so that the protective cover 2 has a shielding position for shielding the forced opening 223 and a avoiding position for avoiding the forced opening 223 .

[0066] When the forced start switch is triggered, the protective cover 2 is moved from the blocking position to the avoidance position, so that the staff can trigger the forced start switch through the forced start opening 223. When the triggering is completed or there is no need to trigger the forced start switch, the safety cover is in the blocking position to prevent gravel or other particles from accidentally triggering the forced start switch through the forced start opening 223.

[0067] The present application does not specifically limit the connection method between the safety cover and the protective cover 2. Preferably, the safety cover is rotatably connected to the protective cover 2, and the rotation axis of the safety cover is located at the bottom of the forced opening 223, so that the safety cover can be in the avoidance position and can move to the shielding position under the action of its own gravity without being subjected to other external forces, so as to ensure the shielding effect of the safety cover on the forced opening 223. In other embodiments, the safety cover can also be slidably connected to the protective cover 2 to open or close the forced opening 223 by sliding.

[0068] Furthermore, the protective cover 2 is provided with a marking area located on the side of the forced opening 223, and the marking area is provided with a reminder slogan to remind the staff so that the staff knows that this is the location of the forced opening switch.
