Cooling performance test rig for cooling system in passenger car, has controller that controls heating device and coolant pump for stimulating operating state of vehicle, where state correlates with vehicle speed

摘要

The rig has a cooling circuit attached to a heating device (4) whose heat output represents a heat input of a vehicle to the cooling circuit. A controller (13) controls the heating device and a coolant pump for stimulating the operating state of the vehicle, where the state correlates with the vehicle speed. The controller controls a measuring unit for measuring temperature-time characteristics. An independent claim is also included for a method for measuring the cooling performance of a cooling system.
