ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a fan rack mounting structure, and more particularly to a detachable fan rack mounting structure, which enables a fan rack to be quickly and detachably mounted on a mounting frame at the back side of a disk drive rack.
A regular disk drive rack has at least one fan rack mounted on its back side to hold a plurality of fans for dissipation of heat. Before mounting the fan rack on the disk drive rack, each fan is connected to the power circuit of the disk drive in the disk drive rack. In case one fan fails to function well, the fan or fans are disconnected with the fan rack from the disk drive rack, and then a soldering gun is used to melt the contacts between the power line of the failed fan and the power circuit of the disk drive in the disk drive rack, enabling the power line of the failed fan to be disconnected from the power circuit of the disk drive in the disk drive rack. The fan rack mounting arrangement complicates the maintenance and repair work of the fans.
SUMMARY OF THE INVENTION
The present invention has been accomplished to provide a detachable fan rack mounting structure, which eliminates the aforesaid problem. According to one aspect of the present invention, the detachable fan rack mounting structure comprises a mounting frame fixedly fastened to a disk drive rack, and a fan rack detachably mounted on the mounting frame to hold at least one fan, wherein the mounting frame comprises a top hook and two protruded portions disposed at a top side, and a plug hole and a retaining hole disposed near a bottom side; the fan rack comprises a springy hook and two locating notches disposed at a top side and respectively forced into engagement with the top hook and protruded portions at the mounting frame, and a bottom plug flange and a positioning block respectively engaged into the plug hole and retaining hole on the mounting frame. According to another aspect of the present invention, the mounting frame further comprises a female connector spaced connected to the power circuit of the disk drive in the disk drive rack, and the fan rack further comprises a female connector, which is automatically connected to the male connector at the mounting frame after installation of the fan rack in the mounting frame.
