More Information
Summary:Multiple-channel flat tube (1) has two through flowable channels (2) or one or more channel sections forming channels which are arranged along the length and along the width adjacent to each other. The area with reduced heat transfer (9) is formed by connecting sections (6) and the connecting sections are arranged from both sides with isolation channels (3). The area with reduced heat transfer is formed by a meander-shaped connecting section. Die Erfindung betrifft ein Mehrkanalflachrohr für Wärmeübertrager, welches mindestens zwei sich entlang seiner Länge erstreckende und entlang seiner Breite im wesentlichen nebeneinander angeordnete und von Fluid durchströmbare Kanäle (2) oder mindestens zwei aus einem oder mehreren dieser Kanäle (2) gebildeten Kanalsektionen (7) aufweist, wobei zwischen den Kanälen (2) oder den Kanalsektionen (7) über die Länge des Flachrohres (1) jeweils ein Bereich mit vermindertem Wärmedurchgang (9) vorgesehen ist, welches dadurch gekennzeichnet ist, dass der Bereich mit vermindertem Wärmedurchgang (9) durch einen Verbindungssteg (6) und beidseitig des Verbindungssteges (6) angeordnete Isolationskanäle (3) gebildet wird. Die Querwärmeleitung innerhalb des Mehrkanalflachrohres wird durch diese Anordnung verringert.
