An edge cooled graphite core aluminum cold plate for use in phased array radar systems, the cold plate including opposing aluminum skins, and a core layer sandwiched between the opposing aluminum skins. The core layer includes graphite surrounded by an aluminum body. The aluminum body includes inwardly directed tabs extending from opposing cooled edges of the cold plate, the inwardly directed aluminum tabs having orifices therethrough. The opposing aluminum skins also includes orifices therethrough aligned with the orifices in the tabs of the aluminum body to reduce the conductivity of the cooled edges of the cold plate thus reducing the temperature gradient between edge mounted heat sources and inwardly mounted heat sources without adversely affecting the structural integrity of the graphite core layer.
