Abstract

La présente invention transmet efficacement une quantité de chaleur que possède un élément de transfert thermique (13), à un corps de réception de chaleur (1) en possédant une configuration dans laquelle l'élément de transfert thermique (13) est mis en adhésion uniformément au corps de réception de chaleur (1) avec une certaine force ou une force plus élevée par un élément de pression, pour faire en sorte que le corps de réception de chaleur (1) atteigne plus vite une température souhaitée. Cette unité d'échange thermique gère la température du corps de réception de chaleur (1) et comporte : l'élément de transfert thermique (13) comportant au moins un élément d'accumulation thermique qui change de phase à une température prédéfinie; et l'élément de pression qui presse l'élément d'accumulation thermique (13) contre le corps de réception de chaleur (1) avec une force de pression supérieure ou égale à une valeur prédéfinie. L'élément de pression fait adhérer l'élément de transfert thermique (13) au corps de réception de chaleur lorsque l'on presse.
