Abstract:
An electronic module comprising:a cooling substrate and an electronic device mounted thereon; a heat sink adjacent said cooling substrate; said cooling substrate having an evaporator chamber adjacent said electronic device, at least one condenser chamber adjacent said heat sink, and at least one cooling fluid passageway connecting said evaporator chamber in fluid communication with said at least one condenser chamber; said cooling substrate comprising projections extending inwardly into said at least one cooling fluid passageway for facilitating cooling fluid flow by capillary action; an evaporator thermal transfer body connected in thermal communication between said evaporator chamber and said electronic device; and at least one condenser thermal transfer body connected in thermal communication between said at least one condenser chamber and said heat sink; said evaporator thermal transfer body and said at least one condenser thermal transfer body each having a higher thermal conductivity than adjacent cooling substrate portions.
