<p>PURPOSE:To make filling at the time of charging an alloy to the whole body of a filling container performable so smoothly, by installing a cut-up part in a heat transfer fin. CONSTITUTION:A sectoral cut-up part 11 is formed in an aluminum heat transfer fin 6. Height (a) of this cut-up part 11 is accorded with a laminated pitch of the heat transfer fin 6, whereby setting of a fin pitch is made so easy. With this constitution, filling at the time of charging an alloy to the whole body of a filling container is made so smoothable and, what is more, the fin pitch becomes constant so accurately. Furthermore, since mutual fins are made contact with each other, efficiency of heat transfer is improved.</p> |
