Description

Technical Field

[0001] This utility model relates to the field of motor heat exchange technology, specifically a motor heat exchange structure. Background Technology

[0002] The electric motor has a stator, which comprises stator laminations. Finally, the motor also includes a housing surrounding the rotor laminations and stator laminations. When the motor converts electrical energy into mechanical energy, it generates heat losses. These heat losses must be dissipated to prevent overheating or damage to the machine.

[0003] The heat exchange process, especially the heat dissipation process, is one of the core aspects of controlling the environmental parameters of electrical equipment. For motors, especially high power density motor systems, the heat dissipation problem is crucial to many indicators such as peak capacity, operational continuity, and reliability.

[0004] Temperature rise is an important indicator in motor design and use, and can reflect the effectiveness of heat exchange to a certain extent. On the one hand, temperature rise reflects the impact of motor heat loss; on the other hand, it is also inseparable from the motor's cooling structure. In related technologies, fluid media are often used to accelerate heat exchange; among them, oil-cooled structures have superior heat conduction capabilities.

[0005] For example, the existing patent publication number CN219999119U provides a motor heat exchange structure, stator core and motor. The seventh oil tank of the device can adopt different shapes, and the first end structure and the second middle structure can adopt different axial length ratios to adapt to different heat exchange capacity requirements. The stator core can adopt a sheet-like component overlapping structure, and the installation and fixing method is flexible, which helps to reduce material consumption and improve production efficiency.

[0006] However, its device is only suitable for meeting the needs of different heat exchange capacities.

[0007] In existing motor heat exchange structures, the heat generated inside the motor casing is not well absorbed and conducted. The range of heat conduction to the outside is relatively small, the heat conduction speed is slow, and the heat exchange range is small, making it inconvenient to connect with external heat exchange structures at multiple locations, resulting in low heat exchange efficiency for the motor. Utility Model Content

[0008] The purpose of this invention is to provide a heat exchange structure for an electric motor to solve the problems of poor heat absorption and conduction by the heat exchange structure, a small range of heat conduction to the outside, and a slow heat conduction speed.

[0009] To achieve the above objectives, this utility model provides the following technical solution: a motor heat exchange structure, including a motor housing, a rotating shaft passing through the inside of the motor housing, a rotor fixed on the surface of the rotating shaft, a stator fixed on the inner surface of the motor housing, and a heat exchange plate installed inside the motor housing.

[0010] Preferably, a first heat exchange box is installed at the bottom of the motor housing, and a heat exchange oil tank is installed in the middle of the interior of the first heat exchange box.

[0011] Preferably, an oil exchange pipe is connected to one side of the heat exchange oil tank, and an oil pump is installed inside the heat exchange oil tank.

[0012] Preferably, a first oil guide pipe is connected to one side of the oil pump, and the other end of the first oil guide pipe is connected to the heat exchange plate.

[0013] Preferably, the first oil guide pipe passes through the first heat exchange box, and the top of the first heat exchange box is connected to the first heat exchange tube.

[0014] Preferably, the heat exchange plate has a heat exchange cavity inside, and heat-absorbing cotton is adhered to the surface of the heat exchange plate.

[0015] Preferably, a second oil guide pipe is connected to the top of the heat exchange plate. The second oil guide pipe has a C-shaped structure, and the top of the second oil guide pipe is located on the outside of the motor housing.

[0016] Preferably, a second heat exchange box is fixed to the top of the motor housing, the second heat exchange box covers the outside of the second oil guide pipe, and a second heat exchange pipe is connected to the side of the second heat exchange box.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model provides multiple heat exchange plates inside the motor housing, heat exchange chambers inside the heat exchange plates, and heat-absorbing cotton bonded to the outside of the heat exchange plates. In this way, the heat generated inside the motor housing can be quickly absorbed and conducted through the heat exchange plates and heat-absorbing cotton, and connected and conducted to the external heat exchange structure.

[0019] 2. This utility model provides a second oil guide pipe at the top of the heat exchange plate for connection and is covered by a second heat exchange box, thereby connecting with the external structure for heat exchange. A first oil guide pipe is provided at the bottom of the heat exchange plate for connection and is covered by a first heat exchange box, thereby connecting with the external structural components for heat exchange.
