Abstract

A deionized-water cooling system for electrical equipment is provided. The system includes a cooling loop in which water comes into contact with the electrical equipment and a deionization bypass connected to the cooling loop. The deionization bypass includes a first filter component configured to remove dissolved oxygen, a second filter component configure to filter solid particles, a deionization cartridge configured to deionize water, and a plurality of valves configured to control a water flow within the deionization bypass.

First claim

What is claimed is:

1 . A deionized (DI)-water cooling system comprising:
a cooling loop in which water comes into contact with the electrical equipment; and a deionization bypass connected to the cooling loop, the deionization bypass comprising:
a first filter component configured to remove dissolved oxygen;
a second filter component configured to filter solid particles;
a deionization cartridge configured to deionize water; and
a plurality of valves configured to control a water flow within the deionization bypass.

2 . The system of claim 1 , wherein the first filter comprises:
a first filter housing; and a first filter cartridge.

3 . The system of claim 2 , wherein the first filter cartridge comprises a bed of metal particles.

4 . The system of claim 3 , wherein the metal particles are comprised of copper.

5 . The system of claim 3 , wherein the metal particles have a diameter range from about 20 μm to about 38 μm.

6 . The system of claim 1 , wherein the second filter component comprises a perforated sheet.

7 . The system of claim 1 , wherein the deionization bypass further comprises an ultraviolet (UV) light system configured to eliminate bacteria.

8 . A deionized (DI)-water cooling system comprising:
a cooling loop in which water comes into contact with the electrical equipment; and a deionization bypass connected to the cooling loop, the deionization bypass comprising:
a first filter component configured to remove dissolved oxygen;
a deionization cartridge configured to deionize water;
an injection pump configured to introduce metal particles to the deionization bypass; and
a plurality of valves configured to control a water flow within the deionization bypass.

9 . The system of claim 8 , wherein the metal particles are comprised of copper, alumina oxide (Al 2 O 3 ) or silver particles.

10 . The system of claim 9 , wherein the metal particles have a diameter range from about 20 μm to about 38 μm.

11 . The system of claim 8 , wherein the first filter cartridge comprises a bed of metal particles.

12 . The system of claim 11 , wherein the metal particles of the bed of metal particles are comprised of copper.

13 . The system of claim 8 , wherein the deionization bypass further comprises an ultraviolet (UV) light system configured to eliminate bacteria.

14 . The system of claim 8 , wherein the deionization bypass further comprises a reservoir configured for a degasification reaction for removal of dissolved oxygen and carbon dioxide from the deionization bypass.

15 . A method for deionized (DI)-water cooling, the method comprising:
pumping water from a facility water system to a DI-water cooling system, wherein DI-water cooling system comprises:
a cooling loop in which water comes into contact with the electrical equipment; and
a deionization bypass connected to the cooling loop;
removing dissolved oxygen and acid from the water in the deionization bypass by using a first filter component;
deionizing the water in the deionization bypass by using a deionization cartridge; and
directing the water to the cooling loop.

16 . The method of claim 15 , further comprising removing corrosion byproducts from the water in the deionization bypass by a second filter component configured to filter solid particles.

17 . The method of claim 15 , further comprising introducing metal particles to the deionization bypass.

18 . The method of claim 15 , wherein the first filter component comprises a bed of metal particles.

19 . The method of claim 18 , wherein the metal particles are comprised of copper.

20 . The method of claim 15 , further comprising exposing the deionization bypass to ultraviolet (UV) light to reduce a bacteria count.
