Turbo-guiding type cooling apparatus

Abstract

A turbo-guiding type cooling apparatus includes a reverse fixed blade unit interposed between the wind exit surface of the fan and the heat sink. The rotation direction of the reverse fixed blade unit is opposite to that of the fan. A receiving chamber is formed under the shaft of the reverse fixed blade unit, and the receiving chamber has at least one-third height of the reverse fixed blade unit. A separation portion extending into the receiving chamber is formed at the center of the top of at least one part of the heat sink. The reverse fixed blade unit includes a reduction cover inward tapered at the periphery of the wind outlet thereof. The height (h 1 ) of the periphery of the reduction cover is the same to or greater than the height (h 2 ) of the periphery of the wind outlet of the reverse fixed blade unit, thereby forming a ring-shaped enclosing type. Therefore, the wind will be smoothly concentrated and the flow direction will be changed. Meanwhile, each of the airflows will be separated by the separation portion and delivered to the heat source of the heat sink.
