Abstract: Disclosed are thermal management for electronic devices and, more particularly, to a thermodynamic system with bi-phase fluid circuits which self-organize internal fluid movement to transfer heat from heat absorption zones to heat dissipation zones. A thermodynamic system may include a plurality of thermal energy absorption (TEA) nodes disposed adjacent to one or more heat sources which are interconnected with one another and also a plurality of thermal energy dissipation (TED) nodes through a capillary system that encloses a bi-phase fluid. As TE is absorbed into the bi-phase fluid at individual TEA nodes local condition changes such as, for example, pressure and/or volume increases induce convection of the absorbed TE away from the individual TEA nodes. As TE dissipates from the bi-phase fluid at individual TED nodes local condition changes such as, for example, pressure and/or volume decreases further induce convection of additional absorbed TE toward the individual TED nodes.
