1. An enclosure assembly to enhance cooling of a hydraulic fracturing power drive unit during operation, the enclosure assembly comprising:
an enclosure body extending at least partially around an enclosure space to house the hydraulic fracturing power drive unit;
one or more heat exchanger assemblies connected to the enclosure body for cooling a process fluid associated with the power drive unit and a fluid pump when connected thereto, the one or more heat exchanger assemblies each including:
one or more intake fan assemblies positioned in fluid communication with an external environment surrounding the enclosure body,
one or more intake fan motors operatively connected to the one or more intake fan assemblies to draw air into the enclosure space at the one or more intake fan assemblies and along an airflow path through the enclosure space when the one or more intake fan motors is activated, and
one or more radiator assemblies for receiving the process fluid, the one or more radiator assemblies positioned adjacent the one or more intake fan assemblies in the airflow path through the enclosure space to cool the process fluid as it flows through the one or more radiator assemblies when the one or more intake fan motors is activated;
one or more outlet fan assemblies operatively connected to one or more outlet fan motors to discharge air from the enclosure space, thereby to maintain a desired temperature of the enclosure space when the one or more outlet fan motors is activated;
one or more temperature sensors positioned to detect a temperature of the enclosure space; and
one or more controllers in electrical communication with the one or more temperature sensors, the one or more controllers operatively connected to one or more of the one or more intake fan motors and the one or more outlet fan motors such that the one or more controllers activates the respective one or more intake fan motors and the one or more outlet fan motors to rotate the respective one or more intake fan assemblies and the one or more outlet fan assemblies and thereby cool the process fluid and maintain a desired temperature of the enclosure space responsive to a predetermined temperature signal from the one or more temperature sensors.
