Cryo Power and Heat Transfer
Abstract
Over the past eight years, researchers at the University of Central Florida have studied high flux heat transfer by flow boiling, pool boiling and spray cooling. These techniques are targeted for cooling high power density devices such as power MOSFETs and diode lasers arrays at both cryogenic and room temperatures. Seven tasks were included. The results of flow boiling and pool boiling with liquid nitrogen were included in earlier annual reports for this contract and therefore are not reported here. This final report includes a study on the simulation and testing of power MOSFETs, thermal management of diode laser arrays, development of compact spray nozzles, and fluid management of spray cooling with multiple nozzles for large surface areas. Several examples of the significant achievements include the development of a microstereolithography apparatus so that micro spray nozzles can be made with great precision; a new way of packaging diode laser arrays which is vastly superior to the state of the art; and a unique and effective way to solve the flooding problems associated with multiple nozzle spray cooling.
