A thermal system is disclosed in thermal communication with an electrical device. In one form the thermal system is a refrigeration system having a compressor, condenser, and evaporator. The electrical device can be disposed within the thermal system such that a working fluid of the thermal system exchanges heat with the electrical device. In one embodiment the thermal system includes a container in which the electrical device is disposed. The working fluid in the container can, but need not, remain in substantially the same physical state when transferring heat with the electrical device.
