Abstract

Micro thermal management devices using bubble in microchannel are under development. The heat removal mechanism of this device consists of phase change and forced convection which occur simultaneously and harmonically. Bubble expansion in horn-shaped microchannel gives directional pumping by low-energy consumption. Several kinds of chips are built and tested. The uncontrollable phenomena of bubbly flow in microchannels and the key factors for further improvement are discussed.
