Thermal Cycle Testing
Overview
Today’s tough testing standards demand performance and reliability regardless of the weather conditions. Standard cold start procedures are now being succeeded with more extreme temperature cycling requirements. Repetitive and extreme temperature cycling conditions that engine and heat exchanger systems will experience throughout their life cycle has become the standard. Q Corporation manufactures glycol, water and oil supply systems capable of providing accurate flow capacities with precision temperature control. Although Q Corporation has several standard packaged offerings, we specialize in custom designed systems, including “refrigerant to coolant” and “brine to coolant” systems.
Use-Case Examples
Product failure testing of Condenser, Radiators, Oil Coolers, Heat Exchangers, Powertrain & Hydraulic Components. Perform to U/L, SAE, JIS and other industrial pressure testing specifications.
Verify long term durability and the effects of extreme thermal cycling on Charge Air Cooler heat exchangers. Simplicity of design and function assures long term performance and dependable results. Automotive to Class 8 CACs.
Thermal shock cooling systems for dynamic cooling applications involving engine cold start testing, heat exchanger thermal cycling including engine, heater core and radiator and critical process cooling.
