Description

Technical Field

[0001] This utility model relates to the field of cooling device technology, specifically to a cooling device for the three electrical components of a tractor. Background Technology

[0002] Pure electric tractor vehicles have become an important force in modern logistics and transportation, especially in short-distance fixed-route transportation, such as in steel mills, docks, and sanitation sectors, where their applications are becoming increasingly widespread. With the continuous advancement of power battery technology, the application scope of pure electric tractor vehicles is constantly expanding.

[0003] It includes what we commonly call the "three major electric components": battery, motor, and motor controller.

[0004] The core objective of battery temperature management is to ensure that the battery operates within a suitable temperature range, typically 25°C to 45°C, thereby optimizing its charge and discharge performance, extending cycle life, and ensuring safe use. During operation, the working status of the water pump and water-cooling unit is adjusted according to temperature control conditions to maintain the ideal battery temperature. After the coolant is cooled by the water-cooling unit, it circulates through the lower battery casing, providing effective cooling for the battery.

[0005] To maintain the motor at a suitable operating temperature, an efficient heat dissipation system is designed inside the motor. This system mainly consists of an electric water pump, a fan, a radiator, and related piping, and its function is to effectively dissipate the excess heat generated by the motor into the surrounding environment.

[0006] Furthermore, the motor controller, as the core component of motor control, plays a crucial role. Located between the battery and the motor, it generates significant current and heat during operation. Therefore, the coolant from the motor cooling system flows through the motor controller to provide necessary heat dissipation. Traditional designs, however, cool the battery, motor, and motor controller separately, each requiring its own cooling system. This not only occupies a large space but also results in numerous, messy, and error-prone wires. Utility Model Content

[0007] The purpose of this utility model is to provide a cooling device for the three electric components of a tractor to solve the above problems. It integrates the cooling systems of the motor and the motor controller, and then packages the battery cooling device with the motor and motor controller cooling device to save space.

[0008] Technical Solution: This utility model provides a cooling device for the three electrical components of a tractor, including: a motor and controller cooling device and a battery cooling device. The motor and controller cooling device includes a housing, a cooler, a water pump, water pipes, and a water temperature sensor. The cooler is located in the middle of the housing and is divided into a cooling area and a pipe area. The water pump is located at the bottom of the cooling area of ​​the housing. The water pipes are divided into an inlet pipe, a filling pipe, and an outlet pipe. One end of the inlet pipe is connected to the water pump, and the other end is connected to an inlet located on the top of the housing. One end of the filling pipe is connected to the water pump, and the other end is connected to the cooler. The outlet pipe has a branch outlet in the middle, which is connected to the cooler. The outlet pipe is horizontally located inside the housing, with outlets on both sides passing through the housing. The water temperature sensor is located on the filling pipe and on both sides where the outlet pipe connects to the branch outlet. The battery cooling device is located above the motor and controller cooling device.

[0009] Furthermore, in the aforementioned cooling device for the three electrical components of a tractor, several heat dissipation holes are provided on the partition plates on both sides of the housing.

[0010] Furthermore, in the aforementioned three-electric cooling device for a tractor, a motor control water tank is installed on one side of the outer casing, and a cable management box is installed on the other side. The motor control water tank is connected to a cooler via a pipe.

[0011] Furthermore, in the aforementioned cooling device for the three electrical components of a tractor, a cooling fan is installed on the outer wall of the cooling zone of the housing.

[0012] Furthermore, in the aforementioned three-electric cooling device for a tractor, there are two water pumps connected to each other via a water pipe, with a water injection pipe connected in the middle of the water pipe.

[0013] Furthermore, in the aforementioned cooling device for the three electrical components of a tractor, a controller is also provided inside the housing to control the operation of the entire cooling system.

[0014] Furthermore, in the aforementioned three-electric cooling device for a tractor, a water tank is provided on the outside of the battery cooling device.
