Claim 22:
23. An injection molding system (1000) comprised of an injection molding machine that injects a flow of injection fluid to a heated manifold that distributes the injection fluid to a flow channel that delivers the injection fluid to a gate of a cavity contained in a mold, the injection molding system including:
a top clamp plate,
an actuator comprised of an electricity driven device interconnected to a rotor, the electricity driven device being adapted to receive electrical energy, rotatably drive the rotor around a drive axis and generate electric drive heat, the rotor being interconnected to a valve pin having a pin axis in an arrangement wherein the valve pin is driven along a linear path of travel along the pin axis,
the actuator including heat conductive walls that form a housing removably mounted to one or the other of the manifold and the top clamp plate (1002), the housing mounting the electricity driven device within an enclosed chamber formed in whole or in part by one or more of the heat conductive walls, the heat conductive walls having an interior surface in thermal conductive contact with the electric drive heat generated by the electricity driven device within the enclosed chamber such that the electric drive heat is received by the heat conductive walls,
a cooler comprised of a tube or channel formed or contained within or in intimate contact with the one or more heat conductive walls, the tube or channel containing a cooling fluid, the tube or channel being adapted to receive the electric drive heat from the one or more heat conductive walls and transmit or conduct the electric drive heat to the cooling fluid contained within the tube or channel,
wherein the actuator is mounted in thermal communication with the manifold such that heat generated by the heated manifold is received by the housing of the actuator, the tube or channel formed or contained within or in contact with the one or more heat conductive walls in an arrangement wherein the manifold heat received by the one or more heat conductive walls is transmitted or conducted to the cooling fluid.
