Abstract

Echangeur de chaleur avec réservoir récepteur, dans lequel le réservoir récepteur est amovible et dans lequel les coûts de production et le poids d'un élément de raccord destiné à relier le réservoir récepteur à un corps d'échangeur de chaleur sont réduits. L'élément (3) de raccord est constitué d'un élément (11) d'interconnexion et d'un élément (12) adaptateur. L'élément (11) d'interconnexion est doté de sections (13b, 13c) de raccord pour un collecteur, les sections de raccord étant reliées de façon à communiquer avec une section (E1) de condensation et une section (E2) de surfusion d'un collecteur (4). L'élément (12) adaptateur est relié de façon à communiquer avec l'élément (11) d'interconnexion et le réservoir récepteur (2), et le réservoir récepteur (2) est relié de façon amovible à l'élément (12) adaptateur. L'élément (11) d'interconnexion est constitué d'un premier élément (13) de dissociation où sont formées les sections (13b, 13c) de raccord et d'un deuxième élément (14) de dissociation joint au premier élément (13) de dissociation.
