Abstract

La présente invention concerne un appareil de réglage de température de dispositif (1) présentant une pluralité d'évaporateurs (20), un condenseur (30), un trajet d'écoulement en phase gazeuse (40) et un trajet d'écoulement en phase liquide (50). Les évaporateurs de la pluralité d'évaporateurs sont agencés côte à côte dans une direction d'agencement prédéterminée, absorbent de la chaleur provenant d'un dispositif cible lors du refroidissement du dispositif cible et provoquent l'évaporation d'un fluide de travail dans une phase liquide. Le condenseur condense le fluide de travail dans une phase gazeuse évaporée par les évaporateurs lors du refroidissement du dispositif cible. Le trajet d'écoulement en phase gazeuse guide le fluide de travail dans une phase gazeuse évaporée par la pluralité d'évaporateurs vers le condenseur. Le trajet d'écoulement en phase liquide guide le fluide de travail dans une phase liquide condensée par le condenseur vers la pluralité d'évaporateurs. Le trajet d'écoulement en phase gazeuse (40) présente une pluralité de canalisations de raccordement en phase gazeuse (41), une section de convergence (42) et une canalisation principale côté phase gazeuse (43). Les canalisations de la pluralité de canalisations de raccordement en phase gazeuse sont chacune raccordées à la pluralité d'évaporateurs et sont des parties à l'extérieur desquelles le fluide de travail dans une phase gazeuse s'écoule à partir des évaporateurs. Les canalisations de la pluralité de canalisations de raccordement en phase gazeuse présentent chacune un absorbeur de tolérance (45) destiné à absorber une tolérance sur la base de la relation de position entre les évaporateurs et le condenseur.
