Abstract

<P>PROBLEM TO BE SOLVED: To suppress increase in cost and power consumption, and collect and diffuse a direction of wind from a fan by a structure which eliminates the necessity of a space around the fan. <P>SOLUTION: Because fins 18 are arranged throughout a blow-out port of a fan 14, the entire wind blown out from the fan 14 can be directed to an optional direction. Further, by making movable parts slidable independently from each other, a wind direction caused by the fins 18 arranged above the center and a wind direction caused by the fins arranged below the center are changeable independently from each other, consequently five wind direction (i.e., entirely upper direction, entirely lower direction, collected to center direction, diffused directions, parallel direction) can be produced and thereby providing versatility. In addition, because a cover 19 has its periphery which has the same size as that of the plurality of fans 14, this mechanism can be adopted even when a sufficient space cannot be secured around the fan 14 for the parallel arrangement of the fins 18, and thereby achieving reduction in the space. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

  The present invention relates to a fan wind direction control mechanism and a wind direction control method, and more particularly to a fan wind direction control mechanism and a wind direction control method that are installed at an outlet in a fan unit installed in a communication device or the like.

  A fan unit is installed to circulate air inside devices such as communication equipment and to cool the heat generating parts. In this fan unit, for example, as shown in FIG. 19, the wind direction control mechanism of the fan installed at the outlet port is provided with a plate 5 for controlling the wind direction from above the finger guard 3 for preventing erroneous insertion into the rotating blade portion. Then, the direction of the wind blown from the fan 2 is controlled. Here, the fan 2 and the finger guard 3 are attached to the fixed plate 1 with screws 4. The wind direction control sheet metal 5 is attached to the fixed plate 1 with screws 6.

  According to the wind direction control mechanism of this fan, as shown in the perspective view of FIG. 20A and the side view of FIG. 20B, the wind direction is controlled in the vertical direction according to the bending direction of the sheet metal 5, The heat generating electronic devices 8 and 9 mounted on the printed boards 7-1 and 7-2 in the apparatus are cooled.

  However, in this fan wind direction control mechanism, the wind direction control is only in one direction by a single sheet metal 5 and does not control the entire wind blown from the fan 2. As shown, the entire wind cannot be used for cooling the electronic devices 8 and 9 and the efficiency is poor. Further, since a space for fixing the sheet metal 5 is necessary around the fan 2, there is no space around the fan 2 when the fans 2 are arranged in parallel to uniformly cool the inside of the apparatus. It is difficult to install.

  Therefore, a fan wind direction control mechanism having a wind guide structure for adjusting the wind direction from the fan is known (for example, see Patent Document 1). The fan wind direction control mechanism described in Patent Document 1 can cool a wide range with a single fan by integrating the fan and the wind guide blade and rotating the wind guide blade with a motor.
