The temperature cycling test chamber operates by subjecting automotive components to a series of controlled temperature and humidity cycles. The process begins with heating or cooling the chamber to a specified setpoint using electric heaters or refrigeration units. Once the desired temperature is reached, the component is exposed to this environment for a predetermined duration. The cycle then transitions to the opposite extreme, either cooling or heating, depending on the initial state. This cycle repeats multiple times, simulating the thermal stresses that components may experience over their operational life. For tests involving humidity, the chamber introduces moisture through steam generators, creating a realistic wet environment.
Operation Procedure
5. Completion and Analysis: Upon completion, retrieve the component and analyze the results. Review logged data for any anomalies or performance issues.
