FLUID COOLING SYSTEM AND METHOD FOR ELECTRONICS EQUIPMENT

A fluid conditioner (1) for use in a tank (110) containing computers, or other electronic devices, immersed in fluid F in the tank. The fluid conditioner (1) comprises a housing (10) having a chamber (38) , an outlet (14), a heat exchanger (18) located in the chamber (38) of the housing, and one or more pumps (16) to pump fluid such that the fluid passes into contact with the heat exchanger (18) in the chamber (38) . The heat exchanger (18) has an inlet (30) for cooling medium to enter the heat exchanger (18) and an outlet (14) for cooling medium to exit the heat exchanger (18). In the upright, operational orientation of the fluid conditioner, the pump and the heat exchanger (18) are vertically spaced relative to one another and the heat exchanger (18) is located above the outlet (14) of the fluid conditioner. In use, fluid Fis drawn into and through the pumps (16) to be discharged from the pumps (16). The fluid F passes into contact with the heat exchanger (18) to thereby cool the fluid F, and the cooled fluid F exits the fluid conditioner (1) via the outlet (14) of the fluid conditioner (1) and passes into the lower region of the tank (110) for circulation through the tank.
