Abstract

A power supply system for a data center includes a cooling circuit, an electrochemical power generator, a sensor, and a processor. The cooling circuit includes a fluid configured to receive heat energy generated by a server located in the data center. The electrochemical power generator is configured to receive and/or generate the fluid of the cooling circuit and to generate electrical energy for the server using the fluid. The sensor is configured to obtain data regarding the server. The processor is configured to control an amount of heat energy transferred from the server to the fluid based on the data.

First claim

What is claimed is:

1. A power supply system for a data center, comprising:
an electrochemical power generator configured to generate a fluid by-product and to generate electrical energy for a server in the data center; and
a cooling circuit configured to:
receive the fluid by-product from the electrochemical power generator,
circulate the fluid by-product within the cooling circuit, and
exchange heat energy between the server and the fluid by-product such that at least a portion of heat energy generated by the server is absorbed by the fluid by-product.

2. The system of claim 1 , wherein the cooling circuit includes a heat transfer device configured to exchange heat energy between the server and the fluid by-product using conduction.

3. The system of claim 1 , wherein the cooling circuit includes a heat pipe configured to exchange heat energy between the server and the fluid by-product.

4. The system of claim 1 , wherein the fluid by-product in the cooling circuit is received by a storage tank.

5. The system of claim 1 , further comprising a regeneration system configured to regenerate the fluid by-product into a reactant using electricity received from a power source.

6. The system of claim 5 , wherein the regeneration system is further configured to deliver the reactant to one or more electrochemical power generators in the data center.

7. The system of claim 1 , wherein the electrochemical power generator is a flow battery.

8. The system of claim 1 , wherein the electrochemical power generator is a fuel cell.

9. A power supply system for a data center, comprising:
an electrochemical power generator configured to generate a by-product as part of an electrochemical reaction and to generate electrical energy for a server in the data center; and
a cooling circuit coupled to the electrochemical power generator and configured to:
circulate the by-product within the cooling circuit, and
exchange heat energy between the server and the by-product such that at least a portion of heat energy generated by the server is absorbed by the by-product.

10. The system of claim 9 , wherein the cooling circuit includes a heat transfer device configured to exchange heat energy between the server and the by-product using conduction.

11. The system of claim 9 , wherein the cooling circuit includes a heat pipe configured to exchange heat energy between the server and the by-product.

12. The system of claim 9 , wherein the by-product in the cooling circuit is received by a storage tank.

13. The system of claim 9 , further comprising a regeneration system configured to regenerate the by-product into a reactant using electricity received from a power source.

14. The system of claim 13 , wherein the regeneration system is further configured to deliver the reactant to a storage tank for reuse by the electrochemical power generator.

15. The system of claim 9 , wherein the by-product is a fluid by-product, and wherein the fluid by-product is contained and transported within a carrier fluid.

16. A power supply system for a data center, comprising:
an electrochemical power generator configured to generate a fluid by-product as part of an electrochemical reaction occurring in the electrochemical power generator for generating electrical energy for a server in the data center; and
a cooling circuit fluidly coupled to the electrochemical power generator and configured to:
circulate the fluid by-product in the cooling circuit, and
exchange heat energy between the server and the fluid by-product.

17. The system of claim 16 , wherein the fluid by-product in the cooling circuit is received by a storage tank.

18. The system of claim 16 , further comprising a regeneration system configured to regenerate the fluid by-product into a reactant using electricity received from a power source.

19. The system of claim 18 , wherein the regeneration system is further configured to deliver the reactant to a storage tank for reuse by the electrochemical power generator.

20. The system of claim 16 , wherein the cooling circuit includes a heat transfer device configured to exchange heat energy between the server and the fluid by-product.
