An electronic assembly is provided having a thermal cooling fluid, such as a liquid, for cooling an electronic device within a sealed compartment. The assembly includes a housing generally defining a sealed fluid compartment, an electronic device disposed within the housing and a cooling liquid for cooling the electronic device. The assembly includes inlet and outlet ports in fluid communication with the sealed fluid compartment for allowing the cooling liquid to pass through the compartment to cool the electronic device. Fluid flow channels are formed in thermal communication with the electronic device within the housing. The fluid channels include channels that allow liquid to flow in thermal communication with the electronic device to cool the device.
