Patent number: 10716241Abstract: An air flow distribution system for cooling server racks includes at least one server rack partially defining a hot aisle and a cold aisle, a first air foil disposed above the server rack, and a second air foil disposed above the first air foil. The first air foil and the second air foil are configured to receive air from the hot aisle, and to form turbulent wake patterns in the cold aisle partially defined by the server rack. The air flow distribution system may include a convex ceiling member above the second air foil. A corresponding method includes causing air to be directed between a first air foil disposed above a server rack and a second air foil disposed above the first air foil to form turbulent wake patterns in the cold aisle.
