Abstract

The invention relates to a novel cooling fan, and is designed to solve the technical problem that a dust removal structure, a motor assembly mounting structure, an easily damaged chip repairing structure and a quick mounting structure in an existing like product are poor in design. An outer frame of the cooling fan is square, square extension side surfaces are respectively arranged on an upper cavity opening and a lower cavity opening of a cylindrical fan blade cavity of the outer frame of the fan, screw holes are respectively formed in end corners of the upper extension side surface and the lower extension side surface, and a motor assembly is fixedly arranged on a middle tube of the outer frame of the fan. The key point is as follows: an inner housing is arranged on one side of the outer frame of the fan, filter cotton and an outer mesh enclosure are arranged at an opening of the inner housing, and the filter cotton is fixed at the opening of the inner housing through the outer mesh enclosure; and a ventilating net and vibrating motors are arranged at the inner diameter of the inner housing, and one end of each vibrating motor is propped against the filter cotton. A screw hole in the other side of the outer frame of the fan is connected with a screw hole of a plate body through a fixing clamping hook, and a chip module is arranged in a chip groove between the upper extension side surface and the lower extension side surface on one side; and a motor coil of the motor assembly is fixed on the middle tube of the outer frame of the fan through a buckle ring.

Description

technical field [0001] The invention relates to a cooling fan, which is a novel cooling fan. Background technique [0002] Cooling fans generally refer to fans used for cooling CPU, graphics cards and other motherboards. Some of them are equipped with heat sinks. In fact, the main purpose is to conduct heat out and blow it into the nearby air to achieve the effect of cooling. But there are also some cooling fans used in electrical cabinets or industrial equipment cabinets. Among them, some similar products adopt the structure of mesh cover and filter cotton, such as the application number 201210232065.X published in the Chinese patent literature, the application publication date is 2012.10.17, the invention name is "an automatic dust removal ventilation filter group", the filter group It includes an outer mesh cover, filter cotton, an inner mesh cover shell, a dust collector and a fan; the opening at one end of the inner mesh cover is covered with filter cotton and the oute...
