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.

Controlling high density liquid cooling system to liquid cool components

Embodiments of the invention provide a system and method for housing electrical components of a high-density liquid cooling unit to liquid cool electrical components. The system includes a first electrical cabinet housing at least one electrical switch and a controller. The first electrical cabinet is swingable outward to open, and the first electrical cabinet opens while the high density liquid cooling system continues to operate to liquid cool electrical components. The system includes a second electrical cabinet housing a first motor drive and a second motor drive. The second electrical cabinet is accessible when the first electrical cabinet swings outward. One of the first motor drive and the second motor drive are replaceable while the high density liquid cooling unit continues to operate.
