  • Patent number: 11871544
    Abstract: 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. An electrical enclosure assembly includes a receptacle and a cover member configured as an air foil.

  • Patent number: 11867426
    Abstract: The cooling systems and methods of the present disclosure involve modular fluid coolers and chillers configured for optimal power and water use based on environmental conditions and client requirements. The fluid coolers include wet media, a first fluid circuit for distributing fluid across wet media, an air to fluid heat exchanger, and an air to refrigerant heat exchanger. The chillers, which are fluidly coupled to the fluid coolers via pipe cages, include a second fluid circuit in fluid communication with the air to fluid heat exchanger and a refrigerant circuit in thermal communication with the second fluid circuit and in fluid communication with the air to refrigerant heat exchanger. Pipe cages are coupled together to allow for expansion of the cooling system when additional cooling capacity is needed. The fluid coolers and chillers are configured to selectively operate in wet or dry free cooling mode, partial free cooling mode, or mechanical cooling mode.

  • Patent number: 10345012
    Abstract: Cooling systems and methods use first and second evaporators and first and second liquid refrigerant distribution units to increase the efficiency of the cooling systems and methods. The first evaporator is in thermal communication with an air intake flow to a heat load, and the first liquid refrigerant distribution unit is in thermal communication with the first evaporator. The second evaporator is disposed in series with the first evaporator in the air intake flow and is in thermal communication with the air intake flow, and the second liquid refrigerant distribution unit is in thermal communication with the second evaporator. A trim compression cycle of the second liquid refrigerant distribution unit is configured to further cool the air intake flow through the second evaporator when the temperature of the first fluid flowing out of a main compressor of the second liquid refrigerant distribution unit exceeds a predetermined threshold temperature.
