1. An energy coupling device for coupling energy into molten metal, said device comprising:
a vibration source comprising a probe, said probe comprising an injection port at or near a tip of the probe, the vibration source further comprising a cooling medium feed which transits an axial length of the vibration source, the vibration source configured to eject a cooling medium from the injection port to a receptor in contact with the molten metal, the receptor is spaced apart from the vibration source; and
an assembly comprising a housing and a cooling channel within the housing;
wherein the tip of the probe is inserted into the cooling channel within the housing of the assembly.
