M113A1/M113A1E1 IMPROVED COOLING SYSTEM (ARMY TANKS)

An improved cooling system (ICS) was developed for the M113A1 vehicle family that provides approximately 15 degrees F coolant temperature reduction under full load, low speed/high tractive effort conditions. The system eliminates the collection of oil and dirt on radiator heat transfer surfaces, provides a negative pressure engine compartment for reducing exhaust fume leakage to the personnel compartment, and allows increased drawdown capacity. The basic configuration of the ICS is compatible with product-improved/up-powered versions of the M113A1 family, which includes personnel, cargo, and weapons carriers, self-propelled mortars, missile carriers, recovery vehicles, and mobile armored command posts. The ICS interchanges positions of the fan and radiator on the current production M113A1, with air flow direction remaining the same. Computer system analysis studies have been performed to optimize system design and generalized work in tracked vehicle cooling system design has been applied.
