Abstract
(EN)
A heat exchanger comprises a plurality of heat transfer tubes in which a refrigerant flows, and fins comprising a helical structure that are provided between adjacent heat transfer tubes. The fins have a plurality of helical members in which wires are formed into helical shapes so that the helical diameters differ and are configured by the smaller diameter helical members being sequentially inserted into helical holes of the larger diameter helical members.

L'invention concerne un échangeur de chaleur qui comprend une pluralité de tubes de transfert de chaleur dans lesquels circule un fluide frigorigène, et des ailettes comprenant une structure hélicoïdale qui sont disposées entre des tubes de transfert de chaleur adjacents. Les ailettes ont une pluralité d'éléments hélicoïdaux dans lesquels des fils sont réalisés sous des formes hélicoïdales, de telle sorte que les diamètres hélicoïdaux diffèrent de façon que les éléments hélicoïdaux de plus petit diamètre sont insérés de manière séquentielle dans des trous hélicoïdaux des éléments hélicoïdaux de plus grand diamètre.
