Abstract

The principles described herein provide a server device having a cooling system that provides an efficient cooling of server device components. The cooling system can include a radiator block having air passageways that are oriented substantially orthogonal to the initial airflow path direction. In addition, the server device can include one or more baffles that create an airflow path that passes through the radiator block multiple times. Moreover, the server device can include various additional features that provide convenient access to electronic components within the server device without diminishing the effectiveness of the cooling system.

First claim

What is claimed is:

1. A server device, comprising:
an elongated chassis having a first end and a second end;
one or more fans positioned within the elongated chassis to draw air in an initial direction from the first end and towards the second end, the initial direction corresponding to a flow direction of the one or more fans;
a radiator block having a first end and a second end, the radiator block being oriented substantially parallel to the flow direction of the one or more fans, the radiator block comprising a plurality of air passageways through which the air passes, the plurality of air passageways being orientated substantially orthogonal to the initial direction;
a first baffle in contact with the first end of the radiator block to re-direct air from the initial direction through the plurality of air passageways in a direction orthogonal to the initial direction;
a second baffle in contact with the radiator block to re-direct air passing through the plurality of air passageways back to the initial direction and towards the second end of the elongated chassis;
one or more cold plates; and
one or more liquid tubes that couple the one or more cold plates to the radiator block.

2. The server device of claim 1 , further comprising one or more additional baffles that further direct an airflow path through the elongated chassis.

3. The server device of claim 1 , wherein the first baffle and the second baffle are each coupled to the elongated chassis.

4. The server device of claim 1 , wherein the first baffle and the second baffle direct the airflow path through the radiator block one time as the airflow path passes between the first end and the second end of the elongated chassis.

5. The server device of claim 2 , wherein the first baffle, second baffle, and one or more additional baffles direct the airflow path through the radiator block multiple times as the airflow path passes between the first end and the second end of the elongated chassis.

6. The server device of claim 5 , further comprising a third baffle in contact with the radiator block.

7. The server device of claim 1 , wherein the first baffle and the second baffle comprise a first flexible baffle and a second flexible baffle.

8. The server device of claim 1 , wherein the first baffle and second baffle direct the airflow path through the elongated chassis when the first baffle and second baffle.

9. The server device of claim 1 , wherein the radiator block comprises a movable radiator block coupled to one or more components within the elongated chassis, wherein the movable radiator block moves to provide access to the one or more components without decoupling from the liquid tubes.

10. The server device of claim 1 , further comprising a hinge pin around which the radiator block rotates.

11. The server device of claim 10 , wherein the hinge pin extends from an interior sidewall of the elongated chassis to an opposing interior sidewall of the elongated chassis.

12. The server device of claim 1 , wherein the radiator block further comprises:
an operating position having an airflow path that passes through the radiator block; and
an open position wherein the radiator block is rotated about a hinge.

13. The server device of claim 1 , wherein the server device further comprises one or more side access openings on the elongated chassis to grant access to one or more component of the server device positioned between the radiator block and a motherboard.

14. A server device, comprising:
an elongated chassis having a first end and a second end;
a radiator block positioned within the elongated chassis between the first end and the second end;
one or more cold plates;
one or more liquid tubes connecting the one or more cold plates to the radiator block;
one or more fans positioned within the elongated chassis to draw air from the first end through a length of the chassis and towards the second end; and
a plurality of baffles that define an airflow path that passes through the radiator block two or more times as the airflow path passes through the chassis from the first end towards the second end.

15. The server device of claim 14 , wherein the radiator block comprises a plurality of air passageways through which the airflow path passes that are oriented substantially orthogonal to an initial direction from the first end and towards the second end.

16. The server device of claim 14 , wherein the radiator block comprises a plurality of air passageways through which the airflow path passes that are oriented at an angle between the first end and towards the second end of the elongated chassis.

17. The server device of claim 14 , wherein the radiator block is slanted upward between the first end and the second end of the elongated chassis.

18. The server device of claim 14 , wherein the radiator block further comprises:
a first end of the radiator block;
a second end of the radiator block; and
a plurality of air passageways through which the airflow path passes that are oriented at an angle relative to a direction defined from the first end of the radiator block and the second end of the radiator block.

19. The server device of claim 18 , wherein the plurality of air passageways are oriented at a plurality of different angles within the radiator block.
