Description

Technical Field

[0001] This utility model relates to the field of vehicle-mounted oil pump technology, and in particular to a pump body structure with a dual cooling system. Background Technology

[0002] With economic development and the rapid development of the automotive industry, users now have higher requirements for vehicle intelligence and comfort, in addition to their needs for vehicle power and stability.

[0003] To ensure the cooling and lubrication of various engine components, electric oil pumps and electric water pumps are required depending on the module to provide power for coolant circulation. The electric pump is powered by an internal motor, which drives the impeller (inner and outer rotors) to circulate the oil, thereby cooling and lubricating the relevant components. Traditional electric pumps require both electric water pumps and electric oil pumps, which cannot meet higher usage requirements, thus necessitating improvement. Utility Model Content

[0004] This utility model provides a pump body structure with a dual cooling system that is easy to control, can effectively reduce product costs, and is equipped with two cooling systems but shares a single motor structure, thus meeting higher cooling requirements. It solves the technical problem that the existing electronic pumps have a single structure, requiring both an electronic water pump and an electronic oil pump, which cannot meet higher practical needs.

[0005] The above-mentioned technical problem of this utility model is solved by the following technical solution: a pump body structure with a dual cooling system, including a pump body, wherein a water cooling system and an oil cooling system are provided inside the pump body, and a controller module and a motor are provided at the top inside the pump body. The water cooling system and the oil cooling system share the same controller module and motor to achieve dual heat dissipation. In this utility model, the water cooling system and the oil cooling system share the same controller module and motor, which greatly reduces the structural volume of the product. Driven by the motor drive shaft, the water cooling system and the oil cooling system cool the controller module and the motor structure respectively. In this utility model, the water cooling system and the oil cooling system can be interchanged, and the pump can be adjusted to use an oil pump or a water pump as needed. The pump body of this utility model greatly reduces the control difficulty and product cost.

[0006] Preferably, the water-cooling system includes an impeller fixed on the motor drive shaft, and a water-cooling cavity is provided inside the pump body, with the impeller close to the controller module cover. In this invention, the water-cooling system and the oil-cooling system share a single controller module and motor, significantly reducing the product's structural volume. Driven by the motor drive shaft, the impeller rotates, causing the water to circulate and cool the controller module.

[0007] Preferably, the water cooling system further includes an inlet and an outlet on the pump body casing, which are connected to the water cooling chamber. Water enters the water cooling chamber through the inlet, cools the controller module via the impeller, and then flows out through the outlet.

[0008] Preferably, the oil cooling system includes a pump head at the bottom, which engages with inner and outer rotors outside the internal motor drive shaft. During the rotation of the motor drive shaft, the inner and outer rotors work together to draw in and discharge oil, cooling the motor structure as the oil flows.

[0009] Preferably, a sealing ring is embedded in the outer wall of the pump head. The sealing ring is used to ensure the sealing performance of the pump head assembly.

[0010] Preferably, the oil cooling system further includes a motor cavity within the pump body, and the pump head has an oil inlet and an oil outlet communicating with the motor cavity. During the rotation of the motor drive shaft, the inner and outer rotors work together to draw in and discharge oil. The oil enters the motor cavity from the oil inlet of the pump head and flows out from the oil outlet of the pump head, and the circulation of the oil cools the motor structure.

[0011] Preferably, the pump body housing has several lugs integrally formed on it. These lugs are used to secure the pump body during assembly using bolts or other components.

[0012] Preferably, the internal structure of the pump body is arranged as a controller module, a water cooling system, and an oil cooling system, or a controller module, an oil cooling system, and a water cooling system. The water cooling system and the oil cooling system in this invention can be interchanged, and the choice between an oil pump and a water pump can be adjusted according to requirements.

[0013] Therefore, the pump body structure of the dual cooling system of this utility model has the following advantages: it can effectively reduce the difficulty of control, effectively reduce the product cost, and is equipped with two cooling systems but share a motor structure, which can meet higher cooling requirements.

[0022] A controller module 3 is installed on the top of the pump body 1. A motor is installed inside the pump body 1. A water cooling system and an oil cooling system are installed at intervals inside the pump body 1. The water cooling system and the oil cooling system share the same controller module 3 and motor to achieve dual heat dissipation.

[0023] The oil cooling system includes a pump head 4 fixed at the bottom of the pump body 1. The pump head 4 is engaged with the inner and outer rotors outside the motor drive shaft 11. A motor cavity is provided inside the pump body 1. An oil inlet 5 and an oil outlet 6 communicating with the motor cavity are provided on the pump head 4.

[0024] A sealing ring 7 is embedded in the outer wall of the pump head 4.
