Abstract

The invention discloses a fan blade cover which relates to the technical field of fans. The fan blade cover comprises a base part as well as a plurality of inner guide blades, a plurality of outer guide blades and a heat dissipation rear cover, wherein the base part is shaped like a round disk, an inner ring is disposed above the base part, an outer ring is disposed above the inner ring, and axesof the base part, the inner ring and the outer ring coincide; and the inner guide blades are fixedly connected to the inner ring and the base part, and the outer guide blades are fixedly connected tothe outer ring and the inner ring; a groove is formed in the lower end face of the base part and used for containing a PCB; the heat dissipation rear cover is fixedly connected to the lower end face of the base part and used for covering the PCB; the base part, the inner ring, the outer ring, the inner guide blades and the outer guide blades are integrally shaped and made of aluminum; and the heatdissipation rear cover is made of aluminum. The fan blade cover disclosed by the invention is integrally shaped and made of aluminum; an electric motor and a fan can be stored at the same time; the structure is simple; and strength is high.

Description

technical field [0001] The invention relates to the field of fan technology, in particular to a fan cover. Background technique [0002] In the existing intelligent cooling engine system, the cooling fan is an important part, which is composed of fan blades, fan cover, motor and other parts. The motor drives the fan blades through the motor shaft to blow and dissipate heat. The fan prevents debris from entering, and is also used to guide the wind to help the fan cool down. [0003] The Chinese utility model "engine cooling fan cover and engine fan" whose publication number is CN202867306U provides a molded engine cooling fan cover, which includes: a body; a support ring formed in the body; a motor mounting portion supported in the ring via spokes; and at least three mounting support portions, each mounting support portion having a lug and a concave connection portion connected to the body, characterized in that the connection of the mounting support portion A groove-shaped...
