AI Technical Summary
Existing wind turbine impellers struggle to meet the motor's heat dissipation requirements in miniaturization and high-power design, resulting in severe overheating.
Design a wind turbine impeller, which has a body connection hole in the middle and axial flow blades on the outside. When the motor drives the impeller to rotate, the axial flow blades dissipate heat from the motor. At the same time, a body boss is set in the impeller body to reduce the space occupied by the motor.
It achieves effective heat dissipation of the motor under high load, reduces the motor's size footprint, and improves the motor's working capacity.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of wind turbines, and in particular to a wind turbine impeller. Background Technology
[0002] Existing appliances such as fans, blowers, and humidifiers are subject to user demands for intelligence, miniaturization, and multi-functionality. While reducing their size, they are required to maintain at least the same or even higher performance, and also to accommodate more electronic devices and sensors. Therefore, there are greater requirements for lightweighting and high power in traditionally larger structures. For motors, this means smaller size and higher power. Under such requirements, heat generation will naturally be more severe. Therefore, it is necessary to design the fan impeller that works with the motor so that it can perform its function while also having a certain heat dissipation effect. Utility Model Content
[0003] The main purpose of this utility model is to provide a fan impeller that can perform its function while also providing a certain degree of heat dissipation for the motor.
[0004] This utility model proposes a wind turbine impeller, wherein the impeller body has a body connection hole in the middle, and the impeller body is connected to a motor through the body connection hole;
[0005] An annular body connection groove is provided on the wind turbine body outside the body connection hole. Multiple inclined axial flow fan blades are provided in the body connection groove. When the motor drives the wind turbine body to rotate, the axial flow fan blades can dissipate heat from the motor.
[0006] Preferably, the outer side of the wind turbine body is provided with an outer wall, and the outer wall is provided with a plurality of inwardly bent blades.
[0007] Preferably, the wind turbine body has a recessed center forming a body boss, and multiple body heat dissipation grooves are provided on the side of the body boss.
[0008] Preferably, the motor connection is located on the bottom inner side of the body boss. By providing the body boss, the volume of electrical components occupied by the motor can be reduced.
[0009] The beneficial effects of the wind turbine impeller of this utility model are as follows:
[0010] 1. By setting multiple inclined axial flow fan blades on the wind turbine body, the motor can be cooled through the axial flow fan blades, thereby improving the motor's working capacity under high load.
[0011] 2. By setting an inwardly recessed body boss, the motor part can be set inside the wind turbine body, thereby reducing the volume of electrical components occupied by the motor. Attached Figure Description
