Title
(EN) DOME SHAPED CAPSULES OF THERMAL ENERGY STORAGE MATERIAL FOR IMPROVED HEAT STORAGE
(FR) CAPSULES EN FORME DE DÔME DE MATÉRIAU DE STOCKAGE D'ÉNERGIE THERMIQUE POUR STOCKAGE DE CHALEUR AMÉLIORÉ
Abstract
(EN)
The invention is directed at articles and devices for thermal energy, storage, and for process of storing energy using these articles and devices. The articles comprise a capsular article 10 having one or more sealed spaces 14, wherein the; sealed spaces encapsulate one or more thermal energy storage materials 26 wherein the capsular article has a first outer radial surface that is generally, concave: and an opposing outer radial surface that is generally convex. Preferred capsular articles are generally dome-shaped. Preferably, the capsular article has one or more fluid passages 16 which are sufficiently large to allow a heat transfer fluid to flow through the one or more fluid passages; and when a heat transfer fluid contacts the capsular article 10 the thermal energy storage material.26 is isolated from- the heat transfer fluid. The invention is also directed at devices including two or more articles arranged so that a fluid, such as a heat transfer fluid, may flow through the fluid passage 16 of an article before, or after flowing through a space between two of the articles. Preferred heat storage devices include a conductive component within the capsule suitable for increasing the heat flow, structural elements between two articles suitable for spacing the articles, or both.

L'invention porte sur des articles et sur des dispositifs pour le stockage d'énergie thermique, et sur des procédés de stockage d'énergie utilisant ces articles et ces dispositifs. Les articles comprennent un article capsulaire (10) ayant un ou plusieurs espaces hermétiquement scellés (14), les espaces hermétiquement scellés encapsulant un ou plusieurs matériaux de stockage d'énergie thermique (26), les articles capsulaires ayant une première surface radiale externe qui est globalement concave, et une surface radiale externe opposée qui est globalement convexe. Des articles capsulaires préférés sont généralement en forme de dôme. De préférence, l'article capsulaire a un ou plusieurs passages de fluide (16) qui sont suffisamment grands pour permettre à un fluide de transfert de chaleur de circuler à travers le ou les passages de fluide ; et, quand un fluide de transfert de chaleur vient en contact avec les articles capsulaires (10), le matériau de stockage d'énergie thermique (26) est isolé vis-à-vis du fluide de transfert de chaleur. L'invention porte également sur des dispositifs comprenant deux ou plusieurs articles agencés de telle sorte qu'un fluide, tel qu'un fluide de transfert de chaleur, peut s'écouler à travers le passage de fluide (16) d'un article avant ou après l'écoulement à travers un espace entre deux des articles. Des dispositifs de stockage de chaleur préférés comprennent un composant conducteur à l'intérieur de la capsule, adapté à accroître le flux de chaleur, des éléments structurels entre deux articles adaptés à espacer des articles, ou les deux.
