Abstract:
1. A heat pipe comprising: a) a microchannel heat absorber comprising at least one layer defining a plurality of microchannels each having a cross-sectional dimension to a center of that microchannel that is about equal to or less than a thermal boundary layer thickness for a working fluid and terminating at a first end thereof in a cool side manifold and at a second end thereof in a warm side manifold, the microchannels adapted to contain the liquid working fluid that absorbs heat and forms a vapor upon flowing therethrough from the first end to the second end, b) a heat sink for receiving and condensing the vapor to reform the liquid working fluid and for discharging the liquid working fluid, and c) one or more pipes flowably connecting the warm side manifold of the heat absorber to the heat sink and flowably connecting the cool side manifold of the heat absorber to the heat sink, wherein the one or more pipes are connected so as to permit simultaneous flow of the vapor from the heat absorber to the heat sink and of the liquid working fluid from the heat sink to the heat absorber when heat is applied to the heat absorber.
