Beschreibung
Zusammenfassung:The present invention is a heat pipe (20) having a specified volume of working fluid determined in relation to the interior volume of the heat pipe (20) and a target temperature TT, to provide self-temperature regulation and pressure management. The heat pipe (20) comprises at least a evaporator region (24) and a condenser region (22) having a known interior volume V and a mass of working fluid given by the relationship Mwf=Dwf at TT x V plus an amount of additional working fluid sufficient to have the rate of evaporation about equal to the rate of condensation for the particular heat pipe configuration, wherein Dwf is the density of the working fluid. Caloduc à volume spécifié de fluide de travail déterminé en relation avec le volume interne du caloduc une température cible TT, assurant une régulation de température autoentretenue et une gestion de pression. Le caloduc comprend au moins une zone d'évaporateur et une zone de condenseur à volume interne connu V et masse de fluide de travail selon la relation Mwf = Dwf à TTx V plus une quantité de fluide de travail suffisante pour donner un taux d'évaporation environ égal au taux de condensation pour la configuration de caloduc particulière.
