Title (EN) THERMAL STORAGE HEAT EXCHANGER STRUCTURES EMPLOYING PHASE CHANGE MATERIALS
(FR) STRUCTURES D'ÉCHANGEUR DE CHALEUR À STOCKAGE THERMIQUE UTILISANT DES MATÉRIAUX À CHANGEMENT DE PHASE
Abstract:
(EN) A heat exchanger includes a housing configured to contain a working fluid. The heat exchanger also includes a plurality of chambers disposed within the housing and arranged so as to be surrounded by the working fluid when the working fluid is within the housing, each chamber configured to contain a phase change material (PCM) that expands upon freezing. The walls of each chamber are formed of a high thermal conductivity material that allows transfer of thermal energy between the working fluid and the PCM in each chamber. The walls of each chamber include expandable bellows configured to deform to increase an internal volume of the chamber as the PCM expands upon freezing.
(FR) Un échangeur de chaleur comprend un logement conçu pour contenir un fluide de travail. L'échangeur de chaleur comprend également une pluralité de chambres disposées à l'intérieur du logement et disposées de manière à être entourées par le fluide de travail lorsque le fluide de travail se trouve à l'intérieur du logement, chaque chambre étant configurée pour contenir un matériau à changement de phase (PCM) qui se dilate lors de la congélation. Les parois de chaque chambre sont constituées d'un matériau à haute conductivité thermique qui permet le transfert d'énergie thermique entre le fluide de travail et le PCM dans chaque chambre. Les parois de chaque chambre comprennent un soufflet extensible conçu pour se déformer afin d'augmenter un volume interne de la chambre lorsque le PCM se dilate lors de la congélation.
