Abstract
An apparatus includes a frame and one or more heat generating elements supported by the frame. A plurality of ports are located at the front portion of the frame, and are electrically coupled to the heat generating elements. A faceplate is coupled to the front portion of the frame and includes one or more port openings to allow access to the ports and a plurality of airflow openings. Each of the airflow openings has a bottom edge aligned with the front portion of the frame and a top edge aligned with the top portion of the frame. The top edges of the airflow openings are set back a predetermined distance from the front portion of the frame.
Claims20
An apparatus comprising:
- a frame comprising a front portion, a rear portion, a top portion, a bottom portion, a right side portion, and a left side portion;
- one or more heat generating elements supported by the frame;
- a plurality of ports located at the front portion of the frame, wherein the ports are electrically coupled to the heat generating elements;
- a faceplate coupled to the front portion of the frame comprising:
- one or more port openings to allow access to the ports;
- and
- a plurality of airflow openings, each of the airflow openings comprising a bottom edge and a top edge, wherein the bottom edge is aligned with the front portion of the frame and the top edge is aligned with the top portion of the frame at a point a predetermined distance from the front portion of the frame.
A system comprising:
- an electronics rack to hold a plurality of electronics modules;
- each of the plurality of electronics modules comprising:
- a frame comprising a front portion, a rear portion, a top portion, a bottom portion, a right side portion, and a left side portion;
- one or more heat generating elements supported by the frame;
- a plurality of ports located at the front portion of the frame, wherein the ports are electrically coupled to the heat generating elements;
- a faceplate coupled to the front portion of the frame comprising:
- one or more port openings to allow access to the ports;
- a plurality of airflow openings aligned with the top portion of the frame;
- and
- a chamfered bottom aligned with the bottom portion of the frame,
- wherein a first electronics module selected from the plurality of electronics modules is mounted above a second electronics module selected from the plurality of electronics modules, such that the chamfered bottom of the faceplate on the first electronics module is substantially aligned with the airflow openings of the faceplate on the second electronics module.
A method comprising:
- installing a plurality of electronics modules in an electronics rack, each electronics module comprising one or more heat generating elements;
- providing power to the heat generating elements in the plurality of electronics modules;
- forcing air between a chamfered bottom of a faceplate on a first electronics module selected from the plurality of electronics modules and a plurality of airflow openings in a second electronics module selected from the plurality of electronics modules;
- and
- cooling the one or more heat generating elements of the second electronics module with the forced air.
