Abstract

La présente invention se rapporte à un procédé de fabrication d’une plaque de transfert de chaleur qui présente une bonne efficacité de transfert de chaleur et qui peut être facilement fabriquée. Un procédé de fabrication d’une plaque de transfert de chaleur comprend une étape de préparation servant à superposer un premier élément métallique (2) et un second élément métallique (3) l’un sur l’autre afin de former un espace creux (K) entre une première rainure (5) située dans le premier élément métallique (2) et une seconde rainure (6) située dans le second élément métallique (3) et à introduire un tuyau de milieu thermique (4) dans l’espace (K). Le procédé comprend également une étape d’agitation de flux entrant servant à introduire un instrument rotatif d’agitation de flux entrant (55) depuis le premier élément métallique (2) et le second élément métallique (3) de la structure provisoirement assemblée, qui est formée lors de l’étape de préparation, et à déplacer l’instrument le long de l’espace (K) afin d’amener un matériau fluide plastique (Q) à s’écouler dans les interstices (P1-P4) formés autour du tuyau de milieu thermique (4), le matériau fluide plastique (Q) ayant été plastifié et fluidisé par chaleur de frottement. La largeur et/ou la hauteur de l’espace (K) sont définies pour être supérieures au diamètre extérieur du tuyau de milieu thermique (4).
