Abstract:
1. A MEMS based two-phase loop thermal system which transfers heat autonomously from one or more heat sources to a heat sink, comprising: a) one or more expandable MEMS devices containing a working fluid; b) one or more MEMS directional devices to control and regulate the flow of the working fluid; c) one or more cooling channels that enable heat transfer from the one or more heat sources to the heat sink via the working fluid; and d) a MEMS condenser adjacent to the heat sink to convert the working fluid from a vapor phase to a liquid phase, wherein the one or more expandable MEMS devices further contain expansion chambers, different from the one or more cooling channels, that are constructed in series or in parallel, making an integrated MEMS controllable expansion chamber.
