Figure 2-36 IDX Indoor Heat Exchanger Consider the following points: In addition to the PU SCMs cold plates, the internal water loop circulates through heat  exchangers that are mounted on each frame in the configuration. These exchangers are in  the path of the exhaust air in the rear of the frames.  Depending on the configuration, these heat exchangers remove up to 93% of the residual  heat from the I/O drawers, PCIe I/O drawer, the air-cooled logic in the CPC drawer, and the  power enclosures. The goal is for two-thirds of the total heat that is generated to be removed  from the room by the chilled water.
