Abstract
Method for and apparatus were fans and cable placed at the ends at the same end of a computer rack drawer. The cable ends are located between the fans and the computing elements. The bulk length of each cable passes through the region where the fans are located. Air, and optionally EMI, sealing are provided by an elastic material near the fans. In this way cables could exit the same tailstock of the drawer where fans are located. The cable ends can receive good cooling, and the distance between the cable ends and computing elements of the drawer is not lengthened by the fan position.
Claims10
An apparatus comprising a drawer of computing elements comprising:
- cables with cable ends;
- plug locations for the cable ends;
- cooling fans;
- computing electronics,
- wherein the plug locations of the cable ends, for the cables exiting a drawer of computing electronics, are located in series along an airflow direction between the cooling fans and the computing electronics, and
- wherein the cables exit from the plug locations in the direction of the cooling fans, and
- wherein the cooling fans are provided on both tailstocks of the drawer;
- a main electromagnetic interference (EMI) shield surrounding at least the computing electronics in the drawer, wherein the fans are located inside the main EMI shield;
- and
- an air blocker,
- wherein the air blocker forms both an air and EMI seal for each of the cables, rather than at the cable ends, and
- wherein the air blocker prevents both air and electromagnetic radiation beyond the fans, and
- wherein the air blocker is formed as an air-and-EMI guard by one or more layers of a deformable electrically conductive material and is held in the drawer between two or more cooling fans.
