Abstract

Disclosed herein are apparatus for a cooler device includes a manifold constructed at least partially of silicon oxide. The manifold includes an array of inlet channels and an array of outlet channels. Each inlet channel has a first depth. The array of outlet channels are interlaced with the array of inlet channels, Each outlet channel has a second depth that is larger than the first depth. Each of the array of outlet channels has a pair of sidewalls separating each outlet channel from adjacent inlet channels of the array of inlet channels.

Claims (46)

1. A cooler device comprising:

a manifold constructed at least partially of silicon, comprising:

an array of inlet channels, each inlet channel having a first depth;

an array of outlet channels interlaced with the array of inlet channels, each outlet channel having a second depth that is larger than the first depth, each of the array of outlet channels having a pair of sidewalls separating each outlet channel from adjacent inlet channels of the array of inlet channels;

a manifold case configured to be in contact with a cold plate and encapsulate the manifold, the array of inlet channels, and the array of outlet channels, the manifold case comprising:

a fluid inlet;

a fluid outlet, wherein the fluid inlet is for receiving coolant into the manifold, and the fluid outlet is for removing the liquid coolant from the; and

at least one vapor outlet, wherein the at least one vapor outlet is for removing a vapor from the manifold.

2. The cooler device of claim 1 , wherein the manifold further comprises an array of inlet guides configured to direct coolant to each inlet channel.

3. The cooler device of claim 2 , wherein:

a center axis of each inlet guide is coaxial to a center axis of each outlet channel;

each inlet guide tapers outwardly away from the center axis of each inlet guide; and

a pair of inlet guides of the array of inlet guides direct coolant to an inlet channel of the array of inlet channels.

4. The cooler device of claim 1 , wherein each inlet channel comprises a plurality of spacer elements disposed along a length of each inlet channel, each of the plurality of spacer elements defining a jetted nozzle profile and are configured to distribute coolant by fluid capillary wicking action along the length of each inlet channel.

5. The cooler device of claim 1 , wherein each inlet channel comprises a plurality of jetted inlets.

6. The cooler device of claim 5 , wherein each of the plurality of jetted inlets comprise a plurality of steps decreasing in width as each jetted inlet extends away from a top surface of each inlet channel.

7. The cooler device of claim 5 , wherein each of the plurality of jetted inlets define a tapered profile decreasing in width as each jetted inlet extends away from a top surface of each inlet channel.

8. The cooler device of claim 1 , wherein the manifold is bonded to an array of bonding posts disposed on a cold plate.

9. A cooler device comprising:

a cold plate;

a manifold constructed at least partially of silicon, comprising:

an array of inlet channels, each inlet channel having a first depth; and

an array of outlet channels interlaced with the array of inlet channels, each outlet channel having a second depth that is larger than the first depth; each of the array of outlet channels having a pair of sidewalls separating each outlet channel from adjacent inlet channels of the array of inlet channels; and

a manifold case configured to be in contact with the cold plate and encapsulate the manifold, the array of inlet channels, and the array of outlet channels, the manifold case comprising:

a fluid inlet;

a fluid outlet, wherein the fluid inlet is for receiving coolant into the manifold, and the fluid outlet is for removing the liquid coolant from the manifold; and

at least one vapor outlet, wherein the at least one vapor outlet is for removing a vapor from the manifold.

10. The cooler device of claim 9 , wherein the manifold further comprises an array of inlet guides configured to direct coolant to each inlet channel.

11. The cooler device of claim 10 , wherein:

a center axis of each inlet guide is coaxial to a center axis of each outlet channel;

each inlet guide tapers outwardly away from the center axis of each inlet guide; and

a pair of inlet guides of the array of inlet guides direct coolant to an inlet channel of the array of inlet channels.

12. A cooler device comprising:

a manifold constructed at least partially of silicon, comprising:

an array of inlet channels, each inlet channel having a first depth; and

an array of outlet channels interlaced with the array of inlet channels, each outlet channel having a second depth that is larger than the first depth, each of the array of outlet channels having a pair of sidewalls separating each outlet channel from adjacent inlet channels of the array of inlet channels, wherein:

each inlet channel comprises a plurality of spacer elements disposed along a length of each inlet channel; and

each spacer element of the plurality of spacer elements defines a jetted nozzle profile and is configured to distribute coolant by fluid capillary wicking action along the length of each inlet channel.

13. The cooler device of claim 12 , wherein the manifold further comprises an array of inlet guides configured to direct coolant to each inlet channel.

14. The cooler device of claim 13 , wherein:

a center axis of each inlet guide is coaxial to a center axis of each outlet channel;

each inlet guide tapers outwardly away from the center axis of each inlet guide; and

a pair of inlet guides of the array of inlet guides direct coolant to an inlet channel of the array of inlet channels.

15. The cooler device of claim 12 , wherein each inlet channel comprises a plurality of jetted inlets.

16. The cooler device of claim 15 , wherein each of the plurality of jetted inlets comprise a plurality of steps decreasing in width as each jetted inlet extends away from a top surface of each inlet channel.

17. The cooler device of claim 15 , wherein each of the plurality of jetted inlets define a tapered profile decreasing in width as each jetted inlet extends away from a top surface of each inlet channel.
