Beschreibung
Zusammenfassung:	A heat exchanger (17) for forced air circulation ovens (10), particularly for baking foods, of the type that comprise two chambers, a baking chamber (13) and a heat exchange chamber (14), between which at least one fan (15) circulates air. The exchanger comprises a burner (19) and, in an upward region, coupling connectors (20) that have an oval profile and are inserted in corresponding complementarily shaped straight vertical tubes (21) that end in an upper manifold (22). The end portion of each one of the vertical tubes (21) is surrounded by an interspace (23) formed by a portion of tube (24) that connects the heat exchange chamber (14) to the manifold (22).
