1. A mobile pump unit comprising:
a mobile trailer having mounted thereon one or more pumps, an internal combustion engine to power the one or more pumps, and a heat exchanger assembly for cooling a fluid;
the heat exchanger assembly comprising:
a heat exchanger having an air inlet that faces the engine, the heat exchanger comprising:
the air inlet for receiving air;
a fluid inlet for receiving the fluid;
a heat exchange surface for transferring heat from the fluid to the air;
an air outlet for discharging the air; and
a fluid outlet for discharging the fluid;
the heat exchanger assembly further comprising:
an air circulation device for moving the air through the heat exchanger; and
an air intake duct that directs the air into the air inlet of the heat exchanger, the air intake duct being configured to resist heated air produced by the engine from entering the air inlet;
wherein the heat exchanger assembly further comprises a service door that provides access to an interior of the heat exchanger assembly;
wherein the heat exchanger is positioned on a front side of the heat exchanger assembly that faces the engine; and
wherein the service door is positioned on a side of the heat exchanger assembly that faces laterally away from the engine or rearwardly away from the engine.
