Résumé

The purpose of this article was to present an experimental investigation of heat transfer in a cryostat without lateral insulation. Analysis enabled the authors to locate the main heat transfer phenomena observed. It appears that the dominant heat transfer modes are radiation in the isolating cavity, conduction in the neck towards the liquid phase and convection between the inner wall of the neck and the cold vapour coming from the liquid bath. This study also showed that the approximation methods generally adopted for the determination of the radiation heat transfer between the external envelope and neck walls are not always valid.
