Direction-adjustable diffusive device

Abstract

A direction-adjustable diffusive device is disclosed to include a heat sink, which has a rotating mechanism positioned on the outside of the heat sink, and a cowling, which has another rotating mechanism correspondingly coupled to the rotating mechanism of the heat sink, and a wind-guiding channel comprising a first wind-guiding hole facing the heat sink. The cowling uses the other rotating mechanism and the rotating mechanism for allowing the cowling to be turned about the heat sink to adjust a heat dissipation direction of the heat sink. Therefore, the cowling can use the other rotating mechanism and the rotating mechanism to rotate relatively to the heat sink, which means that the direction of the cowling can be adjusted through 360° according to the requirements to dissipate heat through the heat sink.

1 . A direction-adjustable diffusive device comprising: 
 a heat sink comprising at least one rotating mechanism, the rotating mechanism positioned outside of the heat sink; and    a cowling comprising at least one another rotating mechanism, the another rotating mechanism correspondingly coupled to the rotating mechanism of the heat sink, and the cowling comprising a wind-guiding channel, the wind-guiding channel comprising a first wind-guiding hole, the first wind-guiding hold facing the heat sink;    wherein, the cowling adjusts a heat dissipation direction of the heat sink by that the another rotating mechanism and the rotating mechanism relatively rotated to the heat sink.
