风扇罩或导风罩是一种结构部件，用于封闭和保护风扇叶片，同时优化气流方向和速度。
风扇罩或导风罩是一种结构部件，设计用于封闭和保护风扇叶片，同时优化气流方向和速度。它通过形成从进气口到排气口的受控气流路径，防止空气再循环，降低噪音，并改善热管理。在工业应用中，它确保持续的冷却性能，保护内部组件免受碎屑影响，并通过防止意外接触运动部件来维持操作安全。 风扇罩/导风罩基于空气动力学原理运行，以高效引导空气。它产生压力差，引导气流通过特定路径，最大限度地减少湍流并最大化散热。通过封闭风扇，它防止空气径向逸出，迫使空气轴向通过系统以冷却目标组件。设计通常包含通风口、管道或挡板，以将空气精确引导到需要的位置。

A fan housing typically refers to the main enclosure that surrounds the entire fan assembly, providing structural support and protection. A fan shroud is often a supplementary component that guides airflow more precisely, such as directing it through a radiator or heat sink. In practice, the terms are sometimes used interchangeably, but shrouds are usually more focused on airflow optimization.
It prevents air from escaping sideways, forcing it to flow in a directed path through the system. This reduces turbulence and recirculation, ensuring that cool air reaches hot components effectively, which can lower operating temperatures by 10-20% compared to unshrouded fans.
For temperatures above 100°C, materials like aluminum alloys or stainless steel are preferred due to their high thermal stability and strength. Plastics may degrade or warp, so they are limited to lower-temperature applications unless specially formulated (e.g., PEEK or PPS).
