Problems solved by technology
Therefore, the temperature of the motor itself will rise, and the motor needs to be dissipated in time. If it cannot be dissipated in time, it will seriously affect the performance and life of the motor.
[0004] At present, the heat dissipation of the motor is mainly due to the linear ribs in the hub rotating, which discharge the heat from the inside of the hub to the outside, or to improve the resistance of the motor to high temperatures. Many products have improved the design of the motor, or the application is more durable. High temperature materials, resulting in an increase in cost

Embodiment Construction
[0030] The principles and features of the present invention will be described below with reference to the accompanying drawings. The examples are only used to explain the present invention, but not to limit the scope of the present invention.
[0031] Patent No. CN207621075U discloses a motor fan cooling hub structure and the cooling fan formed by it, such as figure 1 As shown, the fan hub is provided with several ventilation slots along the edge, and the fan hub is provided with ventilation holes.
[0032] However, the hub ventilation holes of the above-mentioned fans are arranged along the edge of the hub. The area of the holes is small, the capacity of the gas that can enter is small, and the projection surface perpendicular to the motor shaft is a hollow projection structure, so that foreign objects and liquids have Possibility of getting inside the hub.
[0033] like figure 1 and Figure 8 As shown, because the ventilation holes are arranged on the edge, not in the c...

The invention relates to a heat dissipation hub structure and a cooling fan formed therefrom. The outer periphery of the hub structure is provided with fan blades, and the center of the hub mechanism is provided with a fixing hole, and the fixing hole is used to connect with the output shaft of the fan motor. Fixedly connected, the hub structure is provided with a cavity for accommodating the motor, and the end surface of the hub structure perpendicular to the output shaft of the fan motor is provided with a plurality of long ventilation holes, and each of the long ventilation holes is along the The radial arrangement of the hub structure, and the long ventilation holes are used to communicate the cavity with the outer space of the hub structure. Arranging long ventilation holes on the end face of the hub can increase the conduction area between the motor and the outside world, making it easier for outside air to enter the cavity of the hub structure, improve heat exchange efficiency, and reduce the impact of heat generation on the life of the motor.
Description
technical field [0001] The invention relates to the technical field of motor heat dissipation, in particular to a novel heat dissipation hub structure for improving the heat dissipation of the motor and a heat dissipation fan formed by the same. Background technique [0002] Radiator fans, such as those used in automotive radiators, condensers and intercoolers, consist of a hub and blades. The hub is connected with the shaft of the driving source motor, the blades are connected with the outer edge of the hub, and are arranged along the radial direction. When the driving source motor is energized, the motor shaft drives the hub, which in turn drives the blades to rotate in the circumferential direction, thereby generating an air flow that flows along the axial direction. When the airflow passes through the radiator, the coolant with a higher temperature in the radiator can be cooled, and the cooled coolant is returned to the heating components such as the engine through the ...
