Abstract
A computer-implemented method regulates exhaust air temperature from direct interface liquid-cooled (DL) nodes in a rack information handling system (RIHS). The method includes receiving a first input corresponding to a desired ambient temperature of an exterior space and a second input is corresponding to an amount of heat being dissipated from functional components operating within an interior space of at least one LC node. An ambient temperature reading of the exterior space is received. A flow rate is calculated for liquid flowing through an air-to-liquid heat exchange (ATLHE) subsystem that results in an amount of heat exchange in the ATLHE subsystem, which generates exhaust air at a temperature that causes a change in the ambient temperature towards the desired ambient temperature. The flow rate is dynamically adjusted of the liquid flowing through the ATLHE subsystem to the calculated flow rate.
