Abstract
Embodiments for providing cooling airflow through electronic in two different directions is described. An airflow control louver system in an electronic device provides for cooling airflow to be efficiently routed through the electronic device in the two different directions which in turn allows for multiple installation configurations for electronic devices with high powered heat sensitive components.
Claims20
An electronic device comprising:
- a heatsink;
- a first airflow path in a first direction, wherein the first airflow path passes through the heatsink;
- a second airflow path in a second direction different from the first direction, wherein the second airflow path passes through the heatsink;
- a third airflow path in the second direction, wherein the third airflow path bypasses the heatsink;
- and
- an airflow control louver configured to, when in a first position, to direct cooling air along the first airflow path and, when in a second position, allow cooling air to flow along the second airflow path and the third airflow path.
3 more elements
An network switch comprising:
- a heatsink;
- at least one optical network component;
- a first airflow path in a first direction, wherein the first airflow path passes through the heatsink;
- a second airflow path in a second direction, wherein the second airflow path passes through the heatsink;
- a third airflow path in the second direction, wherein the third airflow path bypasses the heatsink to flow to the at least one optical network component;
- and
- an airflow control louver, wherein the airflow control louver in a first position directs cooling air along the first airflow path, and wherein the airflow control louver in a second position allows cooling air to flow along the second airflow path and the third airflow path.
4 more elements
An airflow control louver system comprising:
- an airflow control louver positioned within an enclosed electronic device;
- a first airflow path in a first direction and through a heatsink of the enclosed electronic device;
- a second airflow path in a second direction and through the heatsink of the enclosed electronic device;
- and
- a third airflow path in the second direction and bypassing the heatsink of the enclosed electronic device, wherein the airflow control louver in a first position directs cooling air along the first airflow path, and wherein the airflow control louver in a second position allows cooling air to flow along the second airflow path and the third airflow path.
