Abstract

La présente invention concerne un appareil de réglage de la température d'un équipement, l'appareil comprenant un circuit de fluide actif (10) et une structure de fragmentation (20). Le circuit de fluide actif constitue un tube caloporteur du type thermosiphon. Le circuit de fluide actif comporte un évaporateur (12) destiné à évaporer le fluide actif à l'aide de la chaleur absorbée en provenance de l'équipement (BP) et un condenseur (14) destiné à refroidir et à condenser le fluide actif évaporé par l'évaporateur. Dans le circuit de fluide actif, le fluide actif se déplace entre l'évaporateur et le condenseur. La structure de fragmentation est agencée à l'intérieur du circuit de fluide actif. La structure de fragmentation fragmente les bulles dans le fluide actif sous forme liquide.
