METALLIC ARTICLES HAVING HEAT TRANSFER CHANNELS |
摘要 |
Metallic articles (21) having heat transfer channels are produced by solidification of molten metallic material (3, 4, 6) about preformed channel defining means (5) such that a solidified metallic deposit having heat transfer channels is formed. The channel defining means may be in the form of either solid elements (which are subsequently removed to leave the channels), or conduit elements (which may remain permanently embedded in the article). Moulds, dies, cores and other tools for use in moulding or casting of plastics and metals are particularly suitably formed by the process, the heat transfer channels being used for cooling of the respective articles during use. The molten metallic material is preferably deposited by spray forming utilising one or more sprays of molten metallic material. |
