摘要： A leak tolerant liquid cooling system for electrical components (10) comprises a cooling circuit which contains a pump (17) and conduits (14, 16, 18, 20) that circulate a liquid coolant (LC) past the electrical components (10) and through the bottom chamber (15b) of a purge tank (15). This purge tank (15) also has a top chamber (15a) which is connected to the bottom chamber (15b) through a passageway (15d); and, the bottom chamber (15b) is sized such that the liquid coolant (LC) passes through it with a velocity which is low enough to let any air bubbles in the coolant rise and move by buoyancy through the passageway (15d) into the top chamber (15a). Air is purged from the top chamber (15a) through a valved output port (25) by forcing liquid coolant (LC) into the top chamber (15a) through a valved input port (24). To complete this purge quickly, the passageway (15d) between the purge tank chambers (15a and 15b) is configured in a way which hinders the flow of coolant (LC) from the top chamber (15a) to the bottom chamber (15b) while the coolant (LC) is being forced into the top chamber (15a). As the air purging occurs, the coolant (LC) continues to be pumped past the electrical components (10) through the cooling circuit. Since the pump (17) is not switched ON and OFF during purging, pressure surges in the cooling system do not occur, and switching noise in the voltages to the electrical components (10) is not generated.

摘要： A diffuser unit (24) for allowing non-condensing gases collecting within a heat pipe (10) to be eliminated. The embodiments described herein define a cavity for collection of non-condensing gases such as hydrogen. The housings (26) are arranged such that the heat pipe (10) working fluid in vapor form transfers heat to the walls of the housing (26) defining the collection cavity to raise the wall temperature thus increasing its permeability to the non-condensing gas. Accordingly, when the heat pipe (10) is used in applications where non-condensing gases such as hydrogen tend to diffuse into the heat pipe such as when it is directly heated by a hydrocarbon combustion, such non-condensing gases can be readily eliminated. Such diffusion of non-condensing gases occurs without the requirement of providing a conventional "getter" which uses special material for absorbing or breaking down such non-condensing gases. The diffuser assemblies (24) in accordance with this invention are self-regulating and entirely passive in operation, requiring no external heat inputs or control signals.

摘要： Système de refroidissement par liquide pouvant supporter des fuites destiné à des composants électriques (10). Ledit système comporte un circuit de refroidissement qui comprend une pompe (17) et des conduits (14, 16, 18, 20); la pompe et les conduits font circuler un produit réfrigérant liquide (RL) autour des composants électriques (10) et à travers la chambre inférieure (15b) d'une cuve de purge (15). Cette cuve de purge (15) comporte aussi une chambre supérieure (15a), qui est raccordée à la chambre inférieure (15b) par un passage (15d); et, la chambre inférieure (15b) est dimensionnée de manière que le produit réfrigérant liquide (RL) passe à travers elle à une vitesse suffisamment faible pour que toute bulle d'air dans le produit réfrigérant monte, et, mue par son pouvoir flottant, passe à travers le passage (15d) jusque dans la chambre supérieure (15a). L'air est purgé de la chambre supérieure (15a) au moyen d'un orifice de sortie à clapet (25), le produit réfrigérant liquide (RL) étant refoulé dans la chambre supérieure (15a) par un orifice d'entrée à clapet (24). Afin que cette purge s'effectue rapidement, le passage (15d) entre les chambres de la cuve de purge (15a et 15b) possède une configuration qui entrave l'écoulement du produit réfrigérant (RL) de la chambre supérieure (15a) à la chambre inférieure (15b), alors que le produit réfrigérant est refoulé dans la chambre supérieure (15a). Durant la purge d'air, le produit réfrigérant (RL) continue à passer autour des composants électriques (10) par pompage à travers le circuit de refroidissement. Etant donné que la pompe (17) ne subit pas de commutations marche-arrêt durant la purge, des montées subites de pression ne se produisent pas dans le système de refroidissement, et cela n'engendre pas de bruits de commutation dans les tensions fournies aux composants électriques (10).

摘要： A heat pipe comprising a container (1) having water enclosed therein as a working fluid and made of a material reactive with water to evolve hydrogen gas. The heat pipe is characterized in that the container (1) has placed therein a solid oxidizing agent for oxidizing the hydrogen gas to water. The hydrogen gas produced by the reaction of the working fluid, i.e. water, with the container (1) is oxidized to water by the oxidizing agent without remaining in the form of a gas within the condensing portion of the pipe.

摘要： A container (12) is disposed within a vacuum insulation jacket which surrounds a vessel or pipe which contains or through which flows a hydrogen containing medium. The container holds oxygen under pressure or holds a material which liberates oxygen when exposed to heat and/or reacts with water to liberate oxygen. The container is sealed by means of a membrane (13) of palladium or palladium alloy. A water absorbing material (16) is disposed inside the container. The palladium membrane is thus exposed on its first side facing the interior of the container to a region of relatively high oxygen pressure produced by the oxygen inside the container and low hydrogen partial pressure inside the container, and is exposed on its other side to the vacuum (low oxygen pressure, and higher hydrogen partial pressure as a result of the outgassing or permeation of hydrogen from the medium in contact with the vacuum chamber walls). The palladium acts as a catalyst for the combination of hydrogen and oxygen to form water when hydrogen flows from the vacuum jacket into the container following the hydrogen pressure gradient. The water thus formed is absorbed inside the container using a suitable water absorber, such as a molecular sieve. The method of using the device includes placing it within a vacuum chamber or between two concentrically arranged pipes constituting a vacuum chamber so that the palladium or palladium alloy membrane is in thermal communication with a high temperature surface, such as the surface of the wall of the pipe containing steam or a heat transfer fluid.
