3. Key Components of Liquid Cooled Systems

The basic components in a liquid cooling system as shown in Figure 3.1 include the pump, motor (electrical motor in most of the cases), liquid accumulator or reservoir which is used to compensate for liquid density change for the range of temperature encountered, relief and bypass valves, filter, and other items such as interconnecting tubing, fill and disconnecting fittings. Among them, pump which is a device that moves liquid is the heart of any force-liquid cooling system. The main function of the pump is that it consumes the energy to perform mechanical work by moving the liquid. The discussion here will focus at the pump because of its importance to the system.
