Abstract

L'invention concerne un refroidisseur par évaporation à guidage d'air intégré et son procédé de fabrication, aptes à fabriquer d'un seul tenant une pluralité de plaques barrières, des unités d'échange de chaleur et des guides d'air par l'intermédiaire d'un procédé simple, pour ainsi former des canaux secs et humides. Pour atteindre cet objectif, un refroidisseur d'évaporation par évaporation à guidage d'air intégré de l'invention comprend : de multiples plaques barrières (10, 20, 30, 40) ; de multiples barres (52, 62) positionnées entre les multiples plaques barrières (10, 20, 30, 40) et agencées au niveau de parties centrales tout en étant espacées les unes des autres, constituant ainsi des unités d'échange de chaleur (54, 64) ; et des unités d'espacement (50, 60) comprenant des unités de guidage (51, 61) agencées sur les périphéries des multiples plaques barrières (10, 20, 30, 40), de manière à définir la direction d'écoulement d'un fluide.
