A first coolant circuit extends along the side walls of the cooling box and through the nose portion thereof while the second coolant circuit has a first portion which extends along the side walls adjacent the first circuit and a second portion which is disposed toward the center of the cooling box with respect to both the first cooling circuit and the first portion of the second cooling circuit.
