1. An apparatus for cooling, the apparatus comprising:
at least one divergent cooling element for receiving a flow of a molten film tube, the at least one divergent cooling element comprising a single annular channel operable to feed cooling gas to a cooling gas deflector and a divergent cooling interface, the cooling gas deflector operable for expelling a cooling gas (i) in a path opposing the flow of the molten film tube toward a first exit gap and (ii) in a path with the flow of the molten film tube toward a second exit gap, wherein at least one of the first exit gap and the second exit gap define a minimum gap between the divergent cooling interface and the flow of the molten film tube.
