Abstract

Embodiments disclosed herein include a server drawer. The server drawer may include a lower deck heat exchanger with an inlet, an outlet, and a fluid pump. The server drawer may also include an upper deck heat exchanger located in an upper airflow path after first heat producing elements and before a component of concern, and a manifold. The manifold may include distributors connecting i) the inlet to the upper deck heat exchanger and ii) the outlet to the upper deck heat exchanger. The fluid pump may pump cooled fluid between the upper deck heat exchanger and the lower deck heat exchange.

Claims (19)

1 . A server drawer, comprising:

a lower deck heat exchanger comprising an inlet, an outlet, and a fluid pump;

an upper deck heat exchanger located in an upper airflow path after first heat producing elements and before a component of concern that comprises an electrical component;

a manifold comprising distributors connecting I) the inlet to the upper deck heat exchanger and ii) the outlet to the upper deck heat exchanger, wherein the fluid pump pumps cooled fluid between the upper deck heat exchanger and the lower deck heat exchanger.

2 . The server drawer of claim 1 , further comprising an upper deck fan configured to move air across the upper deck heat exchanger.

3 . The server drawer of claim 1 , further comprising a lower deck fan configured to move air across the lower deck heat exchanger.

4 . The server drawer of claim 1 , further comprising a lower deck fan configured to push air across the lower deck heat exchanger.

5 . The server drawer of claim 1 , wherein the electrical component comprise a selection from the group consisting of: input/output (IO) cards, solid state drives (SSDs), power supplies, optics transceivers, cables, connectors, and external touch surfaces.

6 . The server drawer of claim 1 , further comprising a temperature sensor configured to gather current temperature data from the component of concern.

7 . The server drawer of claim 6 , further comprising a lock configured to prevent opening of the server drawer when the temperature sensors indicate the current temperature exceeds a temperature threshold.

8 . An inter-deck cooling system, comprising:

a first heat exchanger comprising an inlet, an outlet, and a fluid pump configured to fit within a first deck of a server drawer;

a second heat exchanger configured to fit in a second deck of the server drawer; and

a manifold comprising distributors connecting i) the inlet to the second heat exchanger and ii) the outlet to the second heat exchanger, wherein the fluid pump pumps cooled fluid to the second deck heat exchanger from the first heat exchanger.

9 . The cooling system of claim 8 , further comprising a first deck fan configured to move air across the first deck heat exchanger.

10 . The cooling system of claim 8 , further comprising a second deck fan configured to move air across the second deck heat exchanger.

11 . The cooling system of claim 8 , further comprising a temperature sensor configured to gather current temperature data from component of concern that comprises an electrical component within the server drawer.

12 . The cooling system of claim 11 , wherein the electrical component comprise a selection from the group consisting of: IO cards, SSDs, power supplies, optics transceivers, cables, connectors, and external touch surfaces.

13 . The cooling system of claim 8 , further comprising locks configured to prevent opening of the server drawer when the temperature sensors indicate the current temperature exceeds a temperature threshold.
