Fan with fluid flow guide mechanism

具有流体导流机制的风扇

Abstract

本实用新型提供一种具有流体导流机制的风扇,该风扇包括扇框结构及叶轮,扇框结构设有容置空间及形成有进风口及出风口,扇框结构包含围板,其围板设有两个以上导流构件,且任一导流构件设有开口,其开口朝进风口的方向设置,叶轮安装在扇框结构的容置空间内,使叶轮运转时能将扇叶产生的气流经由导流构件进来的气流导引至承载台的外侧面,即其背风面,使气流有效涵盖欲吹拂的发热源,并提升风扇整体的风量与风压。
The utility model provides a fan with a fluid flow guide mechanism. The fan comprises a fan frame structure and a vane wheel, wherein an accommodating space, an air inlet and an air outlet are formed on the fan frame structure; the fan frame structure comprises a surrounding plate; more than two flow guide structural members are arranged on the surrounding plate; an opening is formed on any flow guide structural member and faces the direction of the air inlet; the vane wheel is arranged in the accommodating space of the fan frame structure, so that when the vane wheel runs, air flow produced by fan blades can be guided to the outer side surface, namely a leeward, of a bearing table through air flows from the flow guide structural members; and therefore, the air flow can effectively cover a heating source to be swayed, and the air volume and the air pressure of the whole fan can be increased.
