    • A cooling cell for drawing heat from a light modulator has an enclosure for conducting a fluid coolant. The enclosure has a fluid coolant inlet disposed to receive fluid coolant under pressure and a fluid conduit to provide fluid communication from the fluid coolant inlet to a nozzle. A well cavity surrounds the nozzle and has a number of fins that extend radially upward from a bottom of the well cavity and outward from the well cavity along a shallow cavity that is peripheral to the well cavity and is shallower than the well cavity. The well cavity is formed within a protruding element that protrudes outward from a portion of an external surface of the enclosure. The protruding element provides a component mounting surface that lies behind the bottom of the well cavity. There is at least one fluid coolant discharge outlet for discharging fluid coolant from the enclosure.
