The invention relates to a heat exchanger (1) for an annealing furnace for ex-changing heat between two fluids, comprising a tubular profile which comprises heat exchanger fins on its outside jacket and which is associated on at least one face side (3) with a connecting flange (4) with at least one flow opening (8) for one of the two fluids, especially a hot gas. In order to provide advantageous constructional conditions it is proposed that the profile is a profile tube made of a folded sheet whose heat exchanger fins (7) aligned in the longitudinal direc-tion of the profile are formed by the corrugated profile, especially the corru-gated flanks, of the folded sheet.
L'invention concerne un échangeur thermique (1) de four de recuit pour l'échange thermique entre deux fluides, cet échangeur ayant un profilé tubulaire présentant des ailettes d'échange thermique sur son enveloppe externe, et au moins une de ses faces frontales (3) étant pourvue d'une bride de raccordement (4) dotée d'au moins un orifice d'écoulement (8) pour un des deux fluides, notamment un gaz chaud. L'invention vise à créer une géométrie de conception avantageuse. A cet effet, le profilé est un tube profilé en tôle pliée dont les ailettes d'échange thermique (7) orientées dans le sens longitudinal du tube sont formées par le profil ondulé de la tôle pliée, notamment par les faces des plis.
