Abstract

L'invention concerne un nid d'abeilles qui est utilisé dans le traitement des échappement d'un moteur à combustion interne. Ce nid d'abeille est composé d'une tôle ondulée (2) et d'une tôle de positionnement (1). La tôle de positionnement (1) comporte des cavités (3) parallèles les unes par rapport aux autres et séparées par un intervalle qui équivaut au multiple du pas de l'ondulation de la tôle ondulée. La crête de l'ondulation de la tôle (2) se situe axialement dans la cavité (3) de la tôle (1). L'union des tôles (1) et (2) permet d'obtenir une plaque qui sert à former par enroulement un nid d'abeille en colonne (4). Les avantages de l'invention sont: bonne conduction thermique, meilleure résistance aux vibrations, excellent traitement des échappement des moteurs, durabilité et taille réduite.
