Problems solved by technology

Since the air inside the hub is heated by the heat of the motor and does not exchange with the outside air, and there is not enough air flow, the air temperature in the space inside the hub will gradually increase after a long time of operation, which will reduce the cooling of the motor and cause the temperature of the driving motor Significantly increased, degrading the performance of the motor and affecting safe operation

Abstract

The invention relates to a fan blade hub which comprises a hub body, a hub fan blade and a coupling device, wherein the inner diameter side of the hub body is connected with the hub fan blade, the outer diameter side of the hub body is connected with axial-flow cooling fan blades, the coupling device is connected with the center of the hub body, the fan blade hub is connected with a driving motor through the coupling device, the coupling device can be a coupling insert, the hub fan blade comprises a plurality of hub blades which can be straight blades, fan blade outlets are arranged among the hub blades, the flow line of the outlets is in radial diffusion. The fan blade hub provided by the invention has the advantages that the original space is fully used to arrange the fan blade, the cooling to the driving motor is strengthened under the condition that the strength is not reduced, and the running stability of the motor is improved.

Description

technical field [0001] The invention relates to a wind blade hub. Background technique [0002] At present, the hubs used by cooling fans in automobiles (sedan cars) all adopt a closed structure without exception. Ribs are used on the inside of the hub to increase the strength of the hub. These ribs not only strengthen the strength of the hub while rotating at a high speed, but also The inner side of the hub will disturb the air and generate rotating airflow to cool the motor. [0003] With the improvement of car grades, the use of famous functions and the improvement of performance, the number of parts in the car has increased. When the space of the car body cannot be increased, the interior layout of the car is developing in the direction of compactness. This directly leads to the reduction of the layout space of the car radiator fan, especially the shorter axial distance of the fan. In order to save assembly space, the inner space of the hub is compressed as much as pos...
