Abstract

L'invention se rapporte au domaine de la recherche et des tests. Le procédé de refroidissement d'un couvercle de bain thermostaté d'un dispositif de recherche et de test consiste à faire passer sous pression un flux d'un agent liquide de refroidissement à travers le couvercle du bain thermostaté du dispositif de recherche et de test et à déverser cet agent. Afin d'amener sous pression le d'agent liquide de refroidissement, on utilise une unité autonome de refroidissement liquide avec circulation de l'agent de refroidissement dans un circuit fermé. Le flux d'agent de refroidissement liquide passe à travers un ou plusieurs tubes disposés dans la cavité d'évacuation de vapeurs du couvercle ou sous le couvercle dans la zone de condensation des vapeurs d'eau bouillante de manière à verser cet agent sous pression à travers au moins un radiateur comprenant un ventilateur d'unité autonome de refroidissement liquide avant d'envoyer sous pression l'agent refroidi dans le radiateur vers la cavité du ou des tubes.
