Abstract

L’invention concerne un micro-évaporateur pour la thermorégulation d’un équipement électrique, présentant un port d’entrée (302), un port de sortie (303) et une chambre de circulation d’un fluide caloporteur s’étendant entre lesdits ports (302, 303), et présentant une pluralité de canaux entrecroisés et de colonnes (301) d’une hauteur inférieure à 2 millimètres. Ledit micro-évaporateur comprend au moins une tôle présentant un relief correspondant à l’une des parties au moins de la configuration desdits canaux et colonnes ainsi que desdits ports de sortie et d’entrée, les sommets desdits reliefs s’étendant dans un plan, les fonds desdits reliefs s’étendant dans un second plan, ladite au moins une tôle étant assemblée par liaison mécanique desdits sommets avec une tôle opposée. Figure de l’abrégé : Figure 5The invention relates to a micro-evaporator for thermoregulating electrical equipment, having an inlet port (302), an outlet port (303) and a chamber for circulating a heat transfer fluid extending between said ports. (302, 303), and having a plurality of intersecting channels and columns (301) with a height of less than 2 millimeters. Said microevaporator comprises at least one sheet having a relief corresponding to at least one of the parts of the configuration of said channels and columns as well as of said outlet and inlet ports, the tops of said reliefs extending in a plane, the bottoms of said reliefs extending in a second plane, said at least one sheet being assembled by mechanical connection of said tops with an opposing sheet.
