Abstract

In this modular CDU an expansion tank holds water of the primary loop that circulates through the processor, and a removable tank cover supports a pump, a filter and a finned tube heat exchanger that are all immersed in the water when the cover is in place. The top of the cover carries the piping connections for the primary and secondary loops. Connections to the secondary loop carry chilled water through the heat exchanger tubes. The primary loop inlet carrying heating water from the processor is connected to the filter, and the outlet to the processor is connected to the pump discharge. The tank has fixed baffles that direct water from the filter to the pump in two paths, one that includes the heat exchanger and one that bypasses the heat exchanger.
