摘要

A docking device for a hard disk has a protective box housing an electronic unit including a printed circuit card and a fan arranged in or in the vicinity of an opening formed in a first wall of the protective box. The box also has a location for a hard disk. The fan is arranged in the vicinity of an edge of the printed circuit card so that the air stream driven by said fan sweeps over both main faces of the printed circuit card. The guide is designed to guide at least a portion of the air stream driven by the fan directly to the location for a hard disk.

主权项

1. A docking device for a removable device such as a hard disk, the device comprising a protective box having inside walls and a bottom wall housing an electronic unit including a printed circuit card and fan means arranged in or in the vicinity of an opening formed in a first wall of the protective box, said box also providing a location for a removable device, said fan means being arranged in the vicinity of an edge of the printed circuit card so that the air stream delivered by said fan means sweeps over both main faces of the printed circuit card, guide means being designed to guide at least a portion of the top air stream and at least a portion of the bottom air stream delivered by the fan directly to the location for a removable device, wherein at least one of the inside walls of the box facing the main faces of the printed circuit card is provided with at least one rib and with deflectors suitable for modifying the flow of at least a portion of the air stream driven by the fan means, and wherein the ribs project from the bottom wall of the box and are in contact with the bottom face of the printed circuit card;
wherein the printed circuit card is provided with at least a first ventilation opening allowing at least a portion of the bottom air stream guided by the ribs under the location of the removable device to pass through to reach the top face of the printed circuit card and rejoin the top air stream and wherein the printed circuit is provided with a second ventilation opening allowing at least a portion of the rejoined stream to exhaust.
