Patent ID: 7406835

Claim:
A cooling system for cooling a plurality of heat producing systems, the cooling system comprising: a heat exchanger including first and second cooling zones, the first cooling zone including a first inlet for receiving a first temperature control fluid from a first of the heat producing systems and a first outlet for returning the first temperature control fluid to the first heat producing system, the second cooling zone including a second inlet for receiving a second temperature control fluid from a second of the heat producing systems and a second outlet for returning the second temperature control fluid to the second heat producing system; a first fan assembly disposed proximate the first zone and including a first fan operable to move air across the first zone substantially independently of air moving across any other zone of the heat exchanger, thereby facilitating cooling of the first temperature control fluid as it passes through the first zone; a second fan assembly disposed proximate the second zone and including a second fan independently operable from the first fan to move air across the second zone substantially independently of air moving across any other zone of the heat exchanger, thereby facilitating cooling of the second temperature control fluid as it passes through the second zone; a first shroud disposed proximate the first fan and configured to direct the air moved by the first fan through the heat exchanger, and further configured to inhibit mixing of the air moved by the first and second fans; a second shroud disposed proximate the second fan and configured to direct the air moved by the second fan through the heat exchanger, at least one of the shrouds including a heat conductive material; and a control system for controlling operation of the first and second fans and including a controller attached to a portion of the heat conductive material for dissipating heat from the controller.
