Abstract

A microchannel cooling system used to cool integrated circuits may include a number of microchannels which may be subject to bubble blockage. When bubble formation or nucleation occurs due to heating, the bubbles may become trapped within the microchannels. A valve within the microchannel may automatically operate, at least partially, to close off the microchannel, allowing the bubble to be freed and to be flushed from the channel in some embodiments.
