Evaporative cooling of electrical components

摘要

The invention is a method for increasing the capacity of an electrical component, such as a bus bar, to carry an electrical current. The method comprises the step of exposing the electrical component to an evaporative fluid that is in fluid and thermal contact with the electrical component. Upon heating, fluid undergoes a phase change at least partially to a vapor state. Thus, electrical energy in the form of heat generated by the flow of current is dissipated at least partially by the evaporative fluid. As a result, the temperature of the electrical component is maintained within an acceptable range when carrying the electrical current.
