Abstract

In a data processing system, a temperature sensor is located in the primary loop that carries cooling water through cold plates that are in contact with semiconductor devices, and a control valve is located in the secondary loop that carries chilled water to a heat exchanger that couples the two loops. Thus, the flow of chilled water in the secondary loop is varied with the heat load of the processors. In one example, a shutoff valve is installed in the bypass piping to the control valve. This provision is particularly useful where a number of coolant distribution units are serviced by a common chilled water system. Closing of this shutoff valve reduces the flow of chilled water in the secondary loop to each unit.
