Title:
プレート熱交換器のためのフィン、フィンの製造方法、及びフィンを有するプレート熱交換器
Document Type and Number:
Japanese Patent JP4412955
Kind Code:
B2
Abstract:
The spacer fin for a brazed plate heat exchanger, normally of aluminium or aluminium alloy assembled by furnace brazing, is made from thick sheet metal and has a repeated corrugated pattern on one direction (D2) with a geometrical pitch (P) such that the minimal thickness (e) of the metal is in a ratio of over 0.2 : 1 but lower than 0.8 : 1 relative to the pitch. In the direction (D1) perpendicular to the corrugations the the fin forms legs (3) connecting the corrugation crests (5) and troughs (7) that are brazed to the separating plates of the heat exchanger. In one variant of the design the crests and troughs have projecting lateral edges with rounded surfaces having a radius of 0.2 - 0.5 mm.
