Title
(EN) ENERGY TRANSFER SYSTEM BETWEEN A HOT SOURCE AND A COLD SOURCE
(FR) SYSTEME DE TRANSFERT D'ENERGIE ENTRE UNE SOURCE CHAUDE ET UNE SOURCE FROIDE
Abstract
(EN)
A hot source (A) contains one assembly comprised of at least one capillary evaporator (1A) and at least one condenser (2B) having condensation surfaces with a large curvature radius, and a cold source (B) containing an assembly of the same nature (1B, 2B). The condensers are interconnected by means of a steam conduit (3) and the capillary evaporators are interconnected by means of a liquid conduit (4) so as to form a closed circuit wherein circulates a metered fluid amount so that the complete evaporation takes place in the 'hot' evaporators and the complete condensation takes place in the 'cold' condensers, the other elements being then inactive. The system is reversible and, consequently, interesting gains of weight and room can be achieved for a spatial utilisation.
(FR)
Une source chaude (A) contient un ensemble formé d'au moins un évaporateur capillaire (1A) et d'au moins un condenseur (2B) présentant des surfaces de condensation à grand rayon de courbure, et une source froide (B) contenant un ensemble de même nature (1B, 2B). Les condenseurs sont reliés entre eux par un conduit de vapeur (3) et les évaporateurs capillaires sont reliés entre par un conduit de liquide (4) de façon à former un circuit fermé dans lequel circule une quantité de fluide dosée pour que toute l'évaporation se fasse dans les évaporateurs 'chauds' et toute la condensation dans les condenseurs 'froids', les autres éléments étant alors inactifs. Le système est réversible, d'où gain de poids et place intéressants dans une utilisation spatiale.
