ASSEMBLY FOR TEST APPARATUS WITH COOLING AND VENTING ASSEMBLIES

摘要

A testing apparatus (12) includes a crosshead (151) and a head assembly (150). The head assembly (150) includes a head cover (156) having an interior volume (182). An electric actuator (152), controls and other electric components (158) are located within the interior volume (182, 184), wherein the motor (152), controls and other electric components (158) generate heat when energized. A divider (170) within the interior volume (182, 184) separates a first volume (182) from a second volume (184). The first volume (182) includes the heat generating electric motor (152), controls and electric components (158) and the second volume (184) contains substantially no heat generating components. The head assembly (150) includes at least one fan (202) within the second volume that draws cool air from outside the head cover (156) and forces the cool air through the second volume (184) and into the first volume (182) to remove heat.
