Title:
熱交換器のフィンの製造方法
Document Type and Number:
Japanese Patent JP6747488
Kind Code:
B2
Abstract:
With regard to a fin of a heat exchanger to be used in a region suffering from severe salt damage, it has been proposed to coat the aluminum substrate with a corrosion-resistant organic film. However, in manufacturing of a fin, the cut face obtained by cutting the substrate coated with the coating film has no coating, so that corrosion may proceed from the cut face. A fin (10) of a heat exchanger (4) includes a substrate (20) including aluminum or an aluminum alloy and an organic layer (25) disposed on an end face (11) of the substrate (20).
