Abstract

The invention provides an aluminum fan blade which comprises an annular body integrally formed through aluminum. Cooling ribs perpendicular to the annular face are arranged on the edge of the annular body, the outer ends of the cooling ribs and the outer annular face of the annular body are located on the same straight line, the inner ends of the cooling ribs incline to the annular face to form extending positions, one end of a shaft hole in the center of the annular body is concave inwards, the other end of the shaft hole extends to one side of the cooling ribs to form a reinforcing ring, and installation holes are formed in the ring face of the reinforcing ring. The reinforcing ring is higher than the cooling ribs. By the adoption of the scheme, a better cooling function can be achieved. Besides, the fan blade is more applicable to the compact structure of a mine machine, and accordingly mining efficiency is higher.

Description

technical field [0001] The invention relates to the technical field of fans, in particular to an aluminum fan blade. Background technique [0002] Fan is the customary abbreviation for gas compression and gas delivery machinery in my country. Usually, fans include: ventilators, blowers, and wind generators. Gas compression and gas delivery machinery are machines that convert rotational mechanical energy into gas pressure energy and kinetic energy, and transport the gas out. The fan blade is the main component of the fan, especially the fan blade used in mining machinery. Due to the limited space in the mine, the heat dissipation performance of the blade is often poor, which greatly affects the use effect and service life of the fan. Contents of the invention [0003] The purpose of the present invention is to overcome the disadvantages of the prior art and provide an aluminum fan blade with compact structure and good heat dissipation effect. [0004] In order to achieve ...
