Abstract
A cold plate and an integrated circuit cooling module embodying a cross-hatch coolant flow distribution scheme. Cross hatch flow distribution is achieved by way of two sets of channels which run perpendicular to each other. The first set of channels is formed on a base plate. The second, perpendicular set is includes a set of inlet channels and a set of interleaved outlet channels formed on a distribution plate. In the preferred embodiment, the base and distribution plates are separated by an interposer plate that has nozzles which cause a liquid coolant to impinge, under pressure, on the floor of the base plate.
Claims16
A heat removal apparatus, comprising:
- a first plate having a plurality of inlet channels formed therein and a plurality of outlet channels formed therein and disposed so as to be interleaved with said inlet channels;
- a second plate having a plurality of cooling channels formed therein, said second plate being disposed in communication with said first plate such that said cooling channels are not parallel with said inlet channels and said outlet channels;
- a third plate, having a plurality of nozzles formed therein, said third plate being disposed between said first and second plates such that said nozzles align with said inlet channels;
- an inlet manifold chamber connected to supply a coolant to said inlet channels;
- and
- an outlet manifold chamber connected to receive said coolant from said outlet channels;
- wherein said inlet channels are of a depth that decreases with distance from said inlet manifold chamber.
A heat removal apparatus, comprising:
- a first plate having a plurality of inlet channels formed therein and a plurality of outlet channels formed therein and disposed so as to be interleaved with said inlet channels;
- a second plate having a plurality of cooling channels formed therein, said second plate being disposed in communication with said first plate such that said cooling channels are not parallel with said inlet channels and said outlet channels;
- and
- a third plate, having a plurality of nozzles formed therein, said third plate being disposed between said first and second plates such that said nozzles align with said inlet channels;
- wherein said second plate comprises a plurality of bosses extending therefrom and wherein said third plate has a plurality of openings formed therein disposed to receive said bosses when said third plate is mounted to said second plate.
The heat removal apparatus of claim 9, wherein said third plate further comprises a plurality of elongated openings formed therein, interleaved with said lines.
A heat removal apparatus, comprising:
- a body portion;
- a plurality of cooling plugs;
- a plurality of first compliant members connecting said cooling plugs to said body portion;
- a distribution portion, coupled to said body portion, said distribution portion comprising a coolant manifold, and a plurality of nozzles connected to receive coolant from said coolant manifold and extending into said cooling plugs.
- an outer frame;
- and
- a second compliant member connecting said outer frame to said body portion.
A heat removal apparatus, comprising:
- a first plate having a plurality of inlet channels formed therein and a plurality of outlet channels formed therein and disposed to be interleaved with said inlet channels;
- a second plate having a plurality of cooling channels formed therein, said second plate being disposed in communication with said first plate such that said cooling channels are not parallel with respect to said inlet channels and said outlet channels;
- an inlet manifold chamber connected to supply a coolant to said inlet channels;
- an outlet manifold chamber connected to receive said coolant from said outlet channels;
- and
- a plurality of extended nozzles disposed at least partially within each of said cooling channels and connected to receive said coolant from said inlet channels;
- wherein said first and second plates cooperate to form a flow path from said inlet channels through said nozzles, into said cooling channels and to said outlet channels.
