In a cooling device for cooling synthetic filaments using a cooling medium, in particular for use in the spinning of multifilaments, at least one cooling shaft (21), through which the filaments are passed, is arranged between an entry and exit for filaments. According to the invention, the cooling shaft (21) comprises a seamless, electroformed support (22) with passage-openings (23) which are separated by dykes, with the result that a uniform flow profile of the cooling medium is obtained in the cooling shaft (21) and the filaments are subjected to a uniform cooling treatment.

Dispositif de refroidissement servant à refroidir des filaments synthétiques à l'aide d'un milieu de refroidissement, destiné à être utilisé en particulier dans le filage de multifilaments. Ledit dispositif comporte au moins un conduit de refroidissement (21) dans lequel passent les filaments et qui est placé entre une entrée et une sortie pour les filaments. Selon la présente invention, le conduit de refroidissement (21) comporte un support (22) électroformé exempt de soudure, doté d'ouvertures traversantes (23) séparées par des nervures, si bien que l'on obtient une configuration d'écoulement uniforme du milieu de refroidissement dans le conduit de refroidissement (21) et que les filaments sont soumis à un traitement de refroidissement uniforme.
