Claim Text:
1. A head assembly for a testing apparatus having a crosshead, the head assembly comprising: a head cover having an interior volume; an electric linear actuator within the interior volume, wherein the electric linear actuator generates heat when energized; electric components within the interior volume wherein the control and electric components generate heat when energized; a divider within the interior volume that separates a first volume from a second volume, wherein the first volume includes the heat generating electric linear actuator and the heat generating electric components and the second volume contains substantially no heat generating components; at least one fan within the second volume wherein the at least one fan draws cool air from outside the head cover and forces the cool air through the second volume and into the first volume wherein the cool air removes heat generated by the electric actuator and the electric components; and a flow conduit attached to the divider and opening to the second volume, the electric linear actuator arranged with respect to the flow conduit such that air from the at least one fan flows through the flow conduit and over the electric linear actuator.
