Abstract

L'invention concerne un appareil de conditionnement d'air pour véhicule comprenant un module thermoélectrique, notamment, un appareil de conditionnement d'air pour véhicule qui comporte une voie de circulation pour fluide de travail allant d'une unité d'évaporation à une unité de condensation. L'appareil de conditionnement d'air comprend l'unité d'évaporation qui est en contact avec un côté du module thermoélectrique, au moins une unité d'échange thermique dans laquelle sont appariés des éléments d'échange thermique primaire et secondaire, et une unité de vide prévue sur un côté de la voie de circulation de manière que la différence de pression interne, créée par l'unité de vide sert de force d'entraînement pour faire circuler le fluide de travail. Dans l'unité d'échange thermique, l'élément d'échange thermique primaire comporte une chambre de liquide et une chambre de gaz qui sont respectivement formées sur les deux côtés de l'unité d'évaporation, et l'élément d'échange thermique secondaire comprend un dissipateur thermique qui est en contact thermique avec l'autre côté du module thermoélectrique. L'appareil de conditionnement d'air pour véhicule selon l'invention améliore l'efficacité de transfert du fluide de travail et l'efficacité d'échange thermique par le biais de la force d'entraînement engendrée par la différence de pression créée dans la voie de circulation du fluide de travail et de la force capillaire du liquide de travail créée dans le conduit de transfert de l'unité d'évaporation. L'agencement adéquat du dissipateur thermique et du conduit de refroidissement permet d'améliorer l'efficacité du refroidissement.
