The present disclosure discloses a cold plate type data center device and a data center, which may at least include a cabinet, a heat transfer component, a circulation branch, a circulation component and a detachable mechanism, where a heat dissipation element is arranged in the cabinet. One end of the heat transfer component is in contact with the heat generating spot of the heat dissipation element, and other end of the heat transfer component passes through the cabinet and is positioned in a circulation cavity in the circulation branch. The circulation branch is communicated with the circulation component, such that a refrigerant in the circulation component flows through the circulation branch. The detachable mechanism connects the circulation component to the cabinet, and hermetically connects the circulation branch to the other end of the heat transfer component.

Embodiments of the invention provide a high density liquid cooling system and various monitoring and control methods. Some methods include calculating a heat transfer efficiency of a heat exchanger based on a temperature difference and calculating a total heat rejection value based on the heat transfer efficiency. Some methods include increasing a secondary flow rate in a secondary coolant loop as a maximum allowable pressure is approached to extend an operating time period and avoid thermal shut down of the high density liquid cooling system.

Embodiments of the invention provide a system and method for providing parallel flow paths for a high density liquid cooling system. The system includes a coolant distribution unit including primary loop piping and secondary loop piping. The secondary loop piping includes a first flow path including a first pump, a first filter, and a first shutoff valve. The secondary loop piping includes a second flow path including a second pump, a second filter, and a second shutoff valve. The system includes an inlet y-pipe upstream of both of the first flow path and the second flow path and an outlet y-pipe downstream of both of the first flow path and the second flow path. Each of the first and second shutoff valves alternate between an open position and a closed position.

A liquid cooling system for cooling heating units each having an identical cooling flow channel includes a cooling liquid circulating supply device which is provided with a liquid supply port and a liquid return port and a pipeline system which includes a liquid supply pipe, a liquid return pipe, and a flow distribution subsystem. One end of the liquid supply pipe communicates with the liquid supply port, and the other end is connected to the flow distribution subsystem at a total flow distribution end. One end of the liquid return pipe communicates with the liquid return port, and the other end is connected to the flow distribution subsystem at a total liquid collection end. The flow distribution subsystem connects the total flow distribution end and the liquid inlet of each heating unit and connects the total liquid collection end and the liquid outlet of each heating unit.

A heat dissipation device includes a console box, multiple casings and two flow-spilt assemblies. The casings are vertically superposed on the console box. Each casing has a heat dissipation loop.

Each flow-split assembly has a water reservoir, a connecting tube communicated between the console box and the water reservoir and multiple curved tubes disposed on the water reservoir. The water reservoir is of a rod shape along a direction of the superposing of the casings. The curved tubes are arranged sequentially and spacedly along the water reservoir to communicate between the water reservoir and each casing correspondingly and connect each of the heat dissipation loops.

A printed circuit board comprises: a network controller; a memory controller; a heterogeneous processor; a field-programmable gate array (FPGA); and a non-volatile-media controller. The memory controller comprises: a fabric controller component configured to communicate with the network controller, the heterogeneous processor, the FPGA, and the non-volatile-media controller; and a media controller component configured to manage access relating to data stored in a volatile memory media. The FPGA is configured to perform computations relating to data stored via the non-volatile-media controller. The heterogeneous processor is configured to perform computation tasks relating to data stored via the memory controller. The printed circuit board is configured to be plugged in to a rack with a plurality of other plugged-in circuit boards.

Phased array antennas, such as a multi-function aperture, are limited in performance and reliability by traditional air-cooled thermal management systems. A fuel-cooled multi-function aperture passes engine fuel through heat exchangers that surround the multi-function aperture to provide better heat transfer than can be achieved through air cooling systems. The increased heat transfer and thermal management results in a multi-function aperture with improved performance and reliability.
