  • Patent number: 10098260
    Abstract: A refrigeration system for electronics includes a compressor disposed on a main line and configured to compress a refrigerant in the refrigeration system and a condenser disposed downstream of the compressor on the main line. An evaporator line is in fluid communication with the main line downstream of the condenser and has an evaporator configured to receive heat into the refrigerant from an external heat source. The system also includes an immersion line in fluid communication with main line downstream of the condenser. The immersion line includes an immersion cooling container that is configured to at least partially house electronics such that the electronics are in direct fluid communication with the refrigerant to cool the electronics.

  • Patent number: 9877928
    Abstract: An air damper assembly for regulating an air flow includes a frame, a plurality of elongated damper blade rotatably mounted to the frame, and a drive mechanism for actuating the damper blades between open and closed positions. The drive mechanism includes a gear fixedly secured to a distal end of each of the damper blades and an elongated rack slidably coupled to the frame. The rack meshingly engages the gears such that linear movement of the rack in a first linear direction results in rotational movement of the damper blades in a first rotational direction and linear movement of the rack in a second linear direction opposite the first linear direction results in rotational movement of the damper blades in a second, rotational direction opposite the first rotational direction.
