Abstract

L'invention concerne un distributeur (6a) de fluide de refroidissement dans lequel le fluide de refroidissement entre d'une extrémité et ressort par l'autre extrémité et qui est formé d'une paire d'éléments plaque comprenant une partie (7b) de ramification d'entrée permettant de faire bifurquer la partie où le fluide de refroidissement s'écoule dans une pluralité de parties; une partie de confluence (7c) permettant de faire confluer le fluide de refroidissement bifurqué par la partie (7c); et une partie de ramification de sortie (7d) permettant de faire bifurquer le fluide de refroidissement amené par la partie de confluence (7c) et de l'évacuer. On prévoit par conséquent un distributeur évitant les anomalies de répartition du fluide de refroidissement dans de nombreuses conditions d'utilisation indépendamment du type de fluide de refroidissement et de l'état de l'installation tout en maintenant une perte de pression basse et un conditionneur d'air l'utilisant qui peut fonctionner de manière très efficace sans nécessiter un grand volume de fluide de refroidissement.
