Systems and methods for minimizing airflow bypass and recirculation through a cable channel
An information handling system may include a chassis, a cable channel formed within the chassis, and a sleeve within the cable channel and configured to minimize airflow recirculation in the chassis via the cable channel, the sleeve comprising a cable passage opening for passage of a cable and an obstruction configured to create a seal at the cable passage opening in the absence of the cable from the cable passage opening, such seal restricting airflow through the cable passage opening.
1. An information handling system comprising:
a chassis;
a cable channel formed within the chassis; and
a sleeve within the cable channel and configured to minimize airflow recirculation in the chassis via the cable channel, the sleeve comprising:
one or more sealing features configured to mechanically couple to the cable channel and create a fluidic seal between two sides of the sleeve when the sleeve is present in the cable channel;
a cable passage opening for passage of a cable; and
an obstruction configured to create a seal at the cable passage opening in the absence of the cable from the cable passage opening, such seal restricting airflow through the cable passage opening.
2. The information handling system of claim 1 , wherein the obstruction comprises a cap flexibly coupled to the sleeve and configured to be selectively translated between a closed position in which the cap creates the seal at the cable passage opening and an open position in which the cable passage opening is open for passage of the cable therethrough.
3. The information handling system of claim 1 , wherein the obstruction comprises a removable plug configured to be selectively inserted into the cable passage opening to create the seal at the cable passage opening and selectively removed from the cable passage opening to open the cable passage opening for passage of the cable therethrough.
4. The information handling system of claim 3 , wherein the sleeve further comprises a storage hole for receiving and storing the removable plug when the removable plug is removed from the cable passage opening.
5. The information handling system of claim 1 , wherein the sleeve further comprises:
a second cable passage opening for passage of the cable or a second cable; and
a second obstruction configured to create a seal at the second cable passage opening in the absence of the cable and the second cable from the second cable passage opening, such seal restricting airflow through the cable passage opening.
6. The information handling system of claim 5 , wherein the cable passage opening is shaped differently than the second cable passage opening.
7. The information handling system of claim 5 , wherein the cable passage opening is sized differently than the second cable passage opening.
8. A sleeve configured to engage with a cable channel in order to minimize airflow recirculation in a chassis via a cable channel of the chassis, the sleeve comprising:
one or more sealing features configured to mechanically couple to the cable channel and create a fluidic seal between two sides of the sleeve when the sleeve is present in the cable channel;
a cable passage opening for passage of a cable; and
an obstruction configured to create a seal at the cable passage opening in the absence of the cable from the cable passage opening, such seal restricting airflow through the cable passage opening.
9. The sleeve of claim 8 , wherein the obstruction comprises a cap flexibly coupled to the sleeve and configured to be selectively translated between a closed position in which the cap creates the seal at the cable passage opening and an open position in which the cable passage opening is open for passage of the cable therethrough.
10. The sleeve of claim 8 , wherein the obstruction comprises a removable plug configured to be selectively inserted into the cable passage opening to create the seal at the cable passage opening and selectively removed from the cable passage opening to open the cable passage opening for passage of the cable therethrough.
11. The sleeve of claim 10 , further comprising a storage hole for receiving and storing the removable plug when the removable plug is removed from the cable passage opening.
12. The sleeve of claim 8 , further comprising:
a second cable passage opening for passage of the cable or a second cable; and
a second obstruction configured to create a seal at the second cable passage opening in the absence of the cable and the second cable from the second cable passage opening, such seal restricting airflow through the cable passage opening.
13. The sleeve of claim 12 , wherein the cable passage opening is shaped differently than the second cable passage opening.
14. The sleeve of claim 12 , wherein the cable passage opening is sized differently than the second cable passage opening.
15. A method for forming a sleeve configured to engage with a cable channel in order to minimize airflow recirculation in a chassis via a cable channel of the chassis, the method comprising:
forming one or more sealing features configured to mechanically couple to the cable channel and create a fluidic seal between two sides of the sleeve when the sleeve is present in the cable channel;
forming in the sleeve a cable passage opening for passage of a cable; and
forming an obstruction configured to create a seal at the cable passage opening in the absence of the cable from the cable passage opening, such seal restricting airflow through the cable passage opening.
16. The method of claim 15 , wherein the obstruction comprises a cap flexibly coupled to the sleeve and configured to be selectively translated between a closed position in which the cap creates the seal at the cable passage opening and an open position in which the cable passage opening is open for passage of the cable therethrough.
17. The method of claim 15 , wherein the obstruction comprises a removable plug configured to be selectively inserted into the cable passage opening to create the seal at the cable passage opening and selectively removed from the cable passage opening to open the cable passage opening for passage of the cable therethrough.
18. The method of claim 17 , further comprising a storage hole for receiving and storing the removable plug when the removable plug is removed from the cable passage opening.
19. The method of claim 15 , further comprising:
a second cable passage opening for passage of the cable or a second cable; and
a second obstruction configured to create a seal at the second cable passage opening in the absence of the cable and the second cable from the second cable passage opening, such seal restricting airflow through the cable passage opening.
20. The method of claim 19 , wherein the cable passage opening is shaped differently than the second cable passage opening.
21. The method of claim 19 , wherein the cable passage opening is sized differently than the second cable passage opening.
