Charge Air Cooler Pressure Cycle Machine

Monday, June 05, 2006

This cooling system testing machine is a two station charge air cooler pressure cycle machine for fatigue testing at high temperature. The fixture was designed to accommodate a variety of shapes and sizes of Charge air cooler (CAC) devices. Air pressure to each component is controlled to a programmable target and then released. The machine monitors the fill and decay rate as well as checking for leaks on a programmable interval. Airflow across the face of the coolers are also independently controlled to a programmable target to achieve the desired temperature drop across the test parts. All cycle information is stored to a data file and can be recalled at a later date. As this test is mainly unattended for long periods of time, the machine can e-mail or page an operator in the event of a failure or shut down condition.
