TEST BENCH HAVING TEMPERATURE-CONTROLLED COOLING BLOWER

摘要

The invention relates to a test bench comprising a load device (2) and a blower device (9) for cooling the load device (2). By using one or more temperature sensors (15 through 19), it is possible to capture the temperature in or at the load device (2) and to adjust the speed of a blower motor (10) of the blower device (9) accordingly. Therefore, according to the invention, the blower speed is changed linearly to the change in temperature in the load device (2) in a prescribed range. If one of the temperature sensors determines that a prescribed limit value is exceeded, then the blower is set to maximum speed. If a further, higher temperature limit is exceeded, the load device (2) is switched off.
