Abstract

A cold plate apparatus is disclosed. A cold plate includes a first set of sinusoidal conduits and a second set of sinusoidal conduits formed therein. The first set of sinusoidal conduits is arranged in a first direction, and the second set of sinusoidal conduits is arranged in a second direction. Crests of the first set of sinusoidal conduits overlap troughs of the second set of sinusoidal conduits. Crests of the second set of sinusoidal conduits overlap troughs of the first set of sinusoidal conduits. A first set of header plates is fluidically coupled to the first set of sinusoidal conduits, and a second set of header plates is fluidically coupled to the second set of sinusoidal conduits.

First claim

What is claimed:

1. A cold plate apparatus, comprising:
a cold plate including a first set of sinusoidal conduits formed in the cold plate and a second set of sinusoidal conduits formed in the cold plate;
wherein the first set of sinusoidal conduits is arranged in a first direction;
wherein the second set of sinusoidal conduits is arranged in a second direction;
wherein the first direction is orthogonal to the second direction;
wherein crests of the first set of sinusoidal conduits overlap troughs of the second set of sinusoidal conduits;
wherein crests of the second set of sinusoidal conduits overlap troughs of the first set of sinusoidal conduits;

a first set of header plates substantially adjacent to the first set of sinusoidal conduits and the second set of sinusoidal conduits; and
a second set of header plates substantially adjacent to the first set of sinusoidal conduits and the second set of sinusoidal conduits;
wherein the first set of header plates and the second set of header plates are disposed below and overlap a bottom surface of the cold plate;
a first set of connecting members fluidically coupling the first set of header plates to the first set of sinusoidal conduits; wherein at least one of the first set of header plates include a first guiding vane therein, the first guiding vane being configured to guide coolant fluid from some of the first set of connecting members to others of the first set of connecting members inverting a flow of the coolant fluid in the first set of sinusoidal conduits; and
a second set of connecting members fluidically coupling the second set of header plates to the second set of sinusoidal conduits.

2. The cold plate apparatus of claim 1 , wherein the first set of sinusoidal conduits, the second set of sinusoidal conduits, the first set of header plates, and the second set of header plates are configured to circulate the coolant fluid.

3. The cold plate apparatus of claim 2 , wherein the coolant fluid comprises at least one of propylene glycol or ethylene glycol.

4. The cold plate apparatus of claim 1 , wherein the cold plate, the first set of header plates, and the second set of header plates comprise a metal.

5. The cold plate apparatus of claim 4 , wherein the metal comprises at least one of copper or aluminum.

6. The cold plate apparatus of claim 1 , wherein at least one of the second set of header plates include a second guiding vane therein, the second guiding vane being configured to guide the coolant fluid from some of the second set of connecting members to others of the second set of connecting members inverting a flow of the coolant fluid in the second set of sinusoidal conduits.

7. The cold plate apparatus of claim 1 , wherein a first inlet port is fluidically coupled to the first set of sinusoidal conduits, and a first outlet port is fluidically coupled to the first set of sinusoidal conduits.

8. The cold plate apparatus of claim 7 , wherein a heat exchanger is fluidically coupled to the first inlet port and the first outlet port, and a pump is configured to circulate the coolant fluid in the first set of sinusoidal conduits, the first set of header plates, the first inlet port, the first outlet port, and the heat exchanger.

9. The cold plate apparatus of claim 1 , wherein a second inlet port is fluidically coupled to the second set of sinusoidal conduits, and a second outlet port is fluidically coupled to the second set of sinusoidal conduits.

10. The cold plate apparatus of claim 9 , wherein a heat exchanger is fluidically coupled to the second inlet port and the second outlet port, and a pump is configured to circulate the coolant fluid in the second set of sinusoidal conduits, the second set of header plates, the second inlet port, the second outlet port, and the heat exchanger.

11. The cold plate apparatus of claim 1 , wherein the first set of header plates are in thermal contact with the first set of sinusoidal conduits; wherein the second set of header plates are in thermal contact with the second set of sinusoidal conduits.

12. The cold plate apparatus of claim 1 , wherein the first set of header plates and the second set of header plates form a flat plenum structure.

13. The cold plate apparatus of claim 1 , wherein the flow of the coolant fluid in the first set of sinusoidal conduits is parallel to the bottom surface of the cold plate.
