摘要: A passive thermal actuator is used to control the position of a vent door mounted on an enclosure, to thereby selectively permit cooling air flow to one or more electronic units disposed within the enclosure. The passive thermal actuator is coupled to the vent door, is at least thermally coupled the electronics unit, and is comprised at least partially of a material, such as a shape memory alloy (SMA), that has a shape or volume that varies with electronics unit temperature variations. The passive thermal actuator, in response to the electronics unit temperature variations, selectively moves the vent door between its open and closed positions.

摘要: A wedge cooling apparatus and method for cooling a rotating machine, such as a generator, disperses a spray of cooling fluid into the wedges of the generator. The spray cooling method results in a high heat transfer coefficient of about 2000-3000 W/m2C as opposed to conventional conduction cooling, which has a heat transfer coefficient of about 200-300 W/m2C. The apparatus and method of the present invention efficiently removes heat from high powered, high current density designed generators.
