The essence of the project is to apply cooling that uses capillary pump as an element taking heat away from power elements. The capillary pump is capable of taking away up to a few hundred watts of power from a square centimeter and transporting it on long distances, even up to a few meters (e.g. beyond the converter system). It gives us the possibility of taking away considerable power and separating the heat source from the place of giving up the heat to the environment, which solves the problems of standard cooling systems. Analysis of heat and mass flow in capillary pumped loop capillary pump based on phase diagram was presented. Some simplifications have been assumed and steady state pump working condition has been derived. Using this condition, a capillary pump prototype has been building and testing. Results of steady state and transient experiments have been presented.
