Description

Technical Field

[0001] This utility model relates to the technical field of cooling systems for mining vehicles, specifically, to a motor cooling device and a mining vehicle. Background Technology

[0002] Because mining trucks have a large tonnage, their power motors are mostly dual motors, requiring separate cooling for each motor. Therefore, the existing cooling devices use radiators with two inlets and two outlets, which are independent and not connected. This necessitates the installation of two air vents in the upper water chamber of the radiator, and two compensation inlets at the radiator outlet. Furthermore, these compensation inlets cannot be directly opened on the side of the outlet; a T-shaped steel pipe is required for transition at the outlet. This increases the complexity of the piping connections and the cooling device, making installation and maintenance inconvenient. Utility Model Content

[0003] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a motor cooling device and a mining vehicle, which reduces the complexity of the structure and installation of the motor cooling device to a certain extent.

[0004] The present invention solves the above problems through the following technical solution:

[0005] An electric motor cooling device includes: a radiator assembly and an electric water pump;

[0006] The radiator assembly has at least one water inlet and one air outlet at the top, and at least one water outlet and one compensation water outlet at the bottom. The compensation water outlet is located on the side of one of the water outlets. The radiator assembly has an interconnected upper water chamber and a lower water chamber inside. The water inlet is connected to the upper water chamber, and the water outlet is connected to the lower water chamber, so that the upper water chamber is connected to at least one water inlet and the lower water chamber is connected to at least one water outlet.

[0007] One end of the electric water pump is connected to the outlet of the radiator via a connecting hose, and the other end is connected to the motor or other vehicle components that need to be cooled.

[0011] As a further improvement of this utility model, the upper guard plate of the radiator assembly is provided with welding bolts to connect the transition bracket.

[0012] As a further improvement of this utility model, four welding bolts are arranged in a square shape.

[0013] As a further improvement of this utility model, the low-voltage fuse box is connected to the transition bracket by bolts to be integrated and assembled on top of the radiator assembly.

[0014] As a further improvement of this utility model, the transition bracket includes a connecting part in the shape of "Ω" and a supporting part disposed on the side of the connecting part. The top of the connecting part is provided with a first fixing hole that cooperates with the upper guard plate of the radiator assembly; the bottom of the connecting part is provided with a second fixing hole that cooperates with the low-voltage fuse box.

[0016] Furthermore, this utility model also solves the above problems through the following technical solutions:

[0017] A mining vehicle is equipped with a motor cooling device as described above.

[0018] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0019] This utility model not only integrates the low-voltage fuse box onto the top of the radiator assembly, reducing space occupation, but also allows the radiator inlet and outlet to share a single water chamber. This enables the cooling circuits of the two motors in the mining vehicle to share a single compensating water inlet for coolant replenishment, and the generated water vapor to be discharged to the expansion tank via a single vent. This reduces the layout of related wiring and piping, optimizes the overall vehicle layout, and makes the overall vehicle layout more reasonable and aesthetically pleasing.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1:

The two water inlets are interconnected, and the two water outlets are interconnected; of course, other numbers can also be used, and there is no limitation on this.

[0032] As an alternative, the upper cover of the radiator assembly is fitted with welding bolts 15 from the inside out; in this embodiment, four welding bolts 15 are arranged in a square shape; the transition bracket is connected to the welding bolts on the upper part of the radiator assembly to realize the assembly of the low-voltage fuse box. The low-voltage fuse box is connected to the transition bracket by bolts, thus integrating and assembling it on the upper part of the radiator assembly.

[0033] Preferably, the connecting hose is fixed to the radiator outlet and the electric water pump inlet using clamps; the electric water pump 5 is connected to the vehicle frame via a Z-shaped mounting bracket 6, the specific installation method and location are detailed below. Figure 4 The Z-type mounting bracket has a certain amount of downward adjustment so that both the Z-type mounting bracket and the radiator bracket can be installed and connected to the vehicle frame.

[0034] This motor cooling device cools the two power motors of the vehicle with only one air outlet and one compensating water inlet. The compensating water inlet can be directly opened on the side of the water outlet, eliminating the need to install a T-shaped water pipe between the water outlet and the electronic water pump inlet.

This reduces the layout of related wiring and piping, optimizes the overall vehicle layout, and makes the overall vehicle layout more reasonable and aesthetically pleasing.

[0040] A mining vehicle is equipped with a motor cooling device as described in Example 1. The radiator inlet and the electric water pump outlet are connected to the vehicle's components that need cooling via pipelines. After being cooled by the radiator assembly, the coolant flows out of the radiator outlet and is divided into two paths. After being pressurized by the electric water pump, the coolant flows sequentially through the vehicle's components that need cooling, carrying away the heat generated by the vehicle's components. It then flows back into the radiator assembly from the radiator inlet to cool the heat generated by the vehicle's components in the coolant, achieving the purpose of cooling and heat dissipation. The cooled coolant then flows out of the radiator outlet, and so on, ensuring the safe and efficient operation of the vehicle.
