Title
(EN) WIND TURBINE MOLD B-SURFACE HEATING AND COOLING USING VACUUM BAG WITH FLUID CHANNELS
(FR) CHAUFFAGE ET REFROIDISSEMENT DE SURFACE B DE MOULE D'ÉOLIENNE À L'AIDE D'UN SAC À VIDE AVEC DES CANAUX DE FLUIDE
Abstract
(EN)
Devices, systems, and methods of improving heat transfer between a composite wind turbine blade surface are provided to reduce cure time. The assembly includes molds having heating wires disposed proximate the mold surface for delivering heat to the composite blade during layup and/or resin cure. Additionally, the vacuum bag disposed on top of the composite part includes a plurality of fluid channels for distributing a thermal fluid (e.g. heated/cooled water, air or oil) across the composite surface (opposite the mold surface).
(FR)
L'invention porte sur des dispositifs, des systèmes et des procédés d'amélioration du transfert de chaleur entre une surface de pale d'éolienne composite dans le but de réduire réduire le temps de durcissement. L'ensemble comprend des moules comportant des fils chauffants disposés à proximité de la surface de moule pour délivrer de la chaleur à la pale composite pendant l'empilage et/ou le durcissement de résine. De plus, le sac à vide disposé au-dessus de la partie composite comprend une pluralité de canaux de fluide afin de distribuer un fluide thermique (par ex. de l'eau chauffée/refroidie, de l'air ou de l'huile) à travers la surface composite (à l'opposé de la surface de moule).
