Abstract

A cooling device for an electric component may include a manifold with a coolant section having a coolant inlet trough and a coolant outlet trough. The device may further include a fluid turbulator having a turbulator plate with turbulator fins extending upwardly therefrom, and turbulator inlet openings and outlet openings through the turbulator plate, and a turbulator carrier surrounding the turbulator plate. The fluid turbulator may be installed between the coolant section and the electric component so that a heat exchange reservoir is defined by bottom surface of the electric component, the turbulator plate top surface and the turbulator carrier. Coolant from a coolant source may flow into the coolant inlet trough, through the turbulator inlet opening into the heat exchange reservoir, and out of the heat exchange reservoir through the turbulator outlet opening into the coolant outlet trough to remove heat from the electric component.
