Cooling Requirements
The Motorola MVME197LE VMEmodule is specified, designed, and tested to
operate reliably with an incoming air temperature range from 0° to 55° C (32°
to 131° F) with forced air cooling at a velocity typically achievable by using a
100 CFM axial fan. Temperature qualification is performed in a standard
Motorola VMEsystem 3000 chassis. Twenty-five watt load boards are inserted
in two card slots, one on each side, adjacent to the board under test, to simulate
a high power density system configuration. An assembly of three axial fans,
rated at 100 CFM per fan, is placed directly under the VME card cage. The
incoming air temperature is measured between the fan assembly and the card
cage, where the incoming airstream first encounters the module under test.
Test software is executed as the module is subjected to ambient temperature
variations. Case temperatures of critical, high power density integrated
circuits are monitored to ensure component vendors specifications are not
exceeded.
