A fluidic thermal exchange element adapted to cool a heat generating component includes a thermal conductive element having a first surface that thermally contacts the heat generating component and a second surface having fins in a cell configuration. A cover is fluidically sealed relative to the thermal conductive element to form a cavity and has first and second fluid access points arranged relative to the fins such that cooled fluid flowing from the first access point to the second access point in the cavity interacts with the fins and acquires thermal energy therefrom to create heated fluid at the second access point. A modular radiator receives the heated fluid from the second access point and cools the fluid to create the cooled fluid for recirculation to the first access point. The modular radiator has a plurality of fluid-fluid thermal coupling elements (FFTCEs), each including first and second fluid thermal interface elements disposed in a frame. A plurality of the FFTCEs are stacked upon each other between top and bottom plates to mechanically restrain the FFTCEs, and the top plate comprises a first fluid access port for accepting the heated fluid and directing the heated fluid to flow through access channels in the respective frames of the FFTCEs to provide heat exchange with the respective FFTCEs to provide the cooled fluid at a second fluid access port that is connected to the first fluid access point.
