Problems solved by technology
Existing shrouds are generally made of non-metallic plastic materials through injection molding. However, due to the high brittleness of plastic materials and poor fatigue resistance, after long-term use, due to the impact of cooling fan vibration , resulting in cracks or even breaks on the surface of the fan shroud, which will affect the heat dissipation effect of electronic components

Abstract
The invention provides a method for manufacturing a fan air guide sleeve and a fan air guide sleeve. The method for manufacturing the fan air guide sleeve includes the steps that an appropriate amountof granular glass fibers and an appropriate amount of a non-metallic base material are uniformly mixed to obtain a mixed raw material, wherein the proportion of the quality of the glass fibers in themixed raw material is 13%, and then the mixed raw material is subjected to an injection molding technology to obtain the fan air guide sleeve; the fan air guide sleeve includes a sleeve core and a sleeve shell, the sleeve core and the sleeve shell are coaxially arranged, the outer peripheral surface of the sleeve core is connected with the inner peripheral surface of the sleeve shell through a plurality of flow deflectors, the sleeve core, the sleeve shell, and the flow deflectors are integrally manufactured by using the mixed raw material through the injection molding technology, the mixed raw material includes the granular glass fibers, the proportion of the quality of the glass fibers in the mixed raw material is 13%, by adopting the technical scheme, the elongation, impact resistance,and fatigue resistance of the raw material are enhanced, the service life of the final fan air guide sleeve product is prolonged, cracks on the surface of the fan air guide sleeve are effectively avoided, and the heat dissipation effect is improved.
Description
technical field [0001] The invention belongs to the technical field of fans, and in particular relates to a method for manufacturing a fan shroud and the fan shroud. Background technique [0002] When various electronic equipment or electronic devices are running, the electronic components will generate a lot of heat during operation. In order to protect these electronic components and prevent them from being burned out, it is usually necessary to install cooling devices such as fans on the electronic components. To enable the fan to discharge heat into the air in time, a fan shroud needs to be installed on the heat dissipation fan to guide the flow direction of the airflow and improve the heat dissipation effect. Existing shrouds are generally made of non-metallic plastic materials through injection molding. However, due to the high brittleness of plastic materials and poor fatigue resistance, after long-term use, due to the impact of cooling fan vibration , resulting in c...
