Abstract:
1. An evaporative compact high intensity cooler (ECHIC) for transferring heat from a heat source along a heat conduction surface of the heat source with a two-phase coolant, comprising: a flow passage labyrinth of coolant flow passages and coolant columns intercalated within each of at least four adjacent flow passage laminations that radially and axially radiate from the heat conduction surface proximate a central coolant supply column, the coolant flow passages having cross-sectional areas that increase from an inlet end to an outlet end as they radiate from the central coolant supply column by way of radially increasing the width and by way of at least some of the coolant flow passages having the outlet end coupled to the inlet end of a downstream coolant flow passage that has multiple radially propagating branches, the outlet end of each branch coupling to the inlet end of a further downstream coolant flow passage that has multiple radially propagating branches, to offer the coolant expanding volume as the coolant evaporates due to absorbing heat within the coolant flow passages from the heat conduction surface.
