Method for customizing nucleate boiling heat transfer from electronic units immersed in dielectric coolant

摘要

A method is provided for customizing the heat transfer from the walls of an electronic unit such as a semi-conductor chip or wafer by determining the required heat transfer characteristics of the units; drilling holes of a predetermined size and location in the walls of the unit with a high energy beam in accordance with the required heat transfer characteristics of the unit; immersing the unit in a suitable dielectric coolant so that nucleate boiling will start at approximately the desired wall temperature to obtain the required heat transfer from the unit, thereby providing a uniform wall temperature.
