Patent

CA 2275648

A method and means for arranging heat transport, i.e. cooling or heating, of electrical components, are disclosed. Embodiments of the invention show how one or several flexible tubes (130) are arranged in connection with units (101) comprising electrical components. The units (101) can be enclosed in cabinets (100). The tube (130) can be arranged in a zigzag pattern around the units (101) and pressurized by a fluid from a combined pump and heat exchanger (103). The pressure expands the wall of the tube (130), thus creating thermal contact with the units (101). By flowing fluid in the tube (130) heat can be transported from or to the units (101). Tubes (130) arranged in several cabinets (100) can be connected, either in series or in parallel.

L'invention concerne un procédé et un moyen de transport de la chaleur comme le refroidissement ou la chauffe de composants électriques. Selon l'invention, au moins un tube flexible (130) est placé par rapport à des unités (101) abritant des composants électriques. Ces unités (101) peuvent être logées dans des boîtiers (100). Le tube (130) peut être disposé en zigzag autour des unités (101) et être mis en surpression interne par un fluide provenant d'une pompe combinée à un échangeur de chaleur (103). La pression provoque l'extension de la paroi du tube (130), créant ainsi un contact thermique avec les unités (101). Lorsque le fluide circule dans le tube (130), la chaleur peut être échangée avec les unités (101). Les tubes (130) placés dans plusieurs boîtiers (100) peuvent être connectés soit en série, soit en parallèle.
