Abstract
Système de refroidissement (100) d’un milieu amplificateur laser (30), comprenant un circuit agencé en boucle fermée et configuré pour, en utilisation, recevoir un liquide caloporteur (20) en circulation. Le circuit comprend une cuve (160), pour recevoir le milieu amplificateur laser (30) immergé dans le liquide caloporteur (20), un réservoir amont (150), équipé d’une surverse amont (155) pour fixer l’altitude de la surface libre (S1) du liquide caloporteur (20) dans le réservoir amont, et un réservoir aval (170), équipé d’une surverse aval (175) pour fixer l’altitude de la surface libre (S2) du liquide caloporteur (20) dans le réservoir aval, avec les réservoirs amont et aval disposés de sorte qu’en utilisation, le liquide caloporteur traverse successivement le réservoir amont, la cuve et le réservoir aval. Selon l’invention, l’un au moins parmi le réservoir amont (150), le réservoir aval (170), une ouverture d’évacuation (157) de la surverse amont, et une ouverture d’évacuation (177) de la surverse aval, est monté réglable en altitude. On obtient ainsi un écoulement gravitaire de liquide caloporteur dans la cuve. Figure pour l’abrégé : Figure 1A.Cooling system (100) of a laser amplifying medium (30), comprising a circuit arranged in a closed loop and configured to, in use, receive a circulating coolant (20). The circuit comprises a tank (160), to receive the laser amplifying medium (30) immersed in the heat transfer liquid (20), an upstream tank (150), equipped with an upstream overflow (155) to set the altitude of the free surface (S1) of the heat transfer liquid (20) in the upstream tank, and a downstream tank (170), equipped with a downstream overflow (175) to set the altitude of the free surface (S2) of the heat transfer liquid (20) ) in the downstream tank, with the upstream and downstream tanks arranged so that, in use, the heat transfer liquid passes successively through the upstream tank, the tank and the downstream tank. According to the invention, at least one of the upstream reservoir (150), the downstream reservoir (170), an outlet opening (157) of the upstream overflow, and an outlet opening (177) of the overflow downstream, is mounted adjustable in altitude. A gravity flow of heat transfer liquid is thus obtained in the tank. Figure for the abstract: Figure 1A.
