Temperature-Aging-Test Bench

Longterm-testing of charge air coolers (CAC)

The test bench is designed for long-term tests (endurance test) of e.g. charge air coolers with automatic system control, measurement and data acquisition. The system is equipped with two independent loop systems (Loop 1 & Loop 2). Loop 1 is a pressurized internal loop with air heating. The test air can be heated up to 300°C. Loop 2 represents the external loop and is operated with air under atmospheric conditions to recool the test item. By a water-cooled heat exchanger the test air can be cooled down to 30°C. The air mass flow is measured once central by a venturi tube. The measurements of the test items take place in a test chamber in which up to six test items can be tested simultaneously. The system is controlled by a PC with data acquisition hardware and measurement and control software under LabVIEW.
