  • Patent number: 11859619
    Abstract: A liquid cooling multi-pumping unit comprising a main body and first and second pumps arranged in series is provided. During operation, cooling fluid is sucked via a cooling fluid inlet into a first fluid chamber and then into a first central chamber opening to a plurality of curved blades of a first impeller assembled in a first pump chamber. From there, the cooling fluid travels and is sucked through a fluid distribution channel into a second fluid chamber and then into a second central chamber opening to a plurality of curved blades of a second impeller assembled in a second pump chamber, before exiting through a fluid outlet. The series arrangement of the first and second pumps increases head pressure, and provides sufficient liquid flow in the case where one liquid cooling pump fails.

    Abstract: Refrigeration systems and control methods therefor are described. The refrigeration systems include a main circuit to connect, through a pipeline, a multi-stage compressor, a condenser, an economizer, a main throttling element, and an evaporator. An air supply branch is configured to connect to the air outlet of the economizer and the intermediate stage air inlet of the multi-stage compressor. A liquid injection branch is configured to connect to the intermediate stage air inlet of the multi-stage compressor from a section having a high-pressure liquid-phase refrigerant in the main circuit. Through the design of the liquid injection branch, the liquid-phase refrigerant can be introduced when vibration or noise of the unit exceeds a limit. The liquid-phase refrigerant, in the form of droplets, can effectively absorb the sound wave energy in the compressor pipeline to reduce an overall discharge pulsation of the compressor and reduce the noise and vibration of the condenser.

  • Publication number: 20150124405
    Abstract: An electronic device includes a fan field replaceable unit (FRU). The fan FRU includes a fan FRU chassis defining an airflow pathway through the fan FRU. A fan within the fan FRU chassis causes air to flow along the airflow pathway. The fan FRU further includes an edge connector located at a front face of the fan FRU out of the way of the airflow pathway. Accordingly, the edge connector does not block airflow through the fan FRU thus maximizing the efficiency of the fan FRU and the cooling of the electronic device.
