Agencement de connexion pour un système de chauffage

摘要

The connecting arrangement has a tube holder (2) extending along the horizontal axis (X1) and a tube section of heat exchanger tube extending from tube holder. The holder has a base support (2.1) having a horizontally extending upper surface (2.1a) and protrusions (2.2) extending from upper surface and having sidewalls (2.2a). The sidewalls are arranged such that the tube section is held non-positively in alternate tubular layers extending along another horizontal axis, such that ratio of number of sidewalls with tube surfaces to number of alternative tubular layers is less than 4.
