Abstract

Viele Wärmeübertragungsvorrichtungen weisen aufgrund unsymmetrischer Anströmungen oder ungleichmäßiger Strömungswiderstände relativ schlechte Kühlerwirkungsgrade auf.
Erfindungsgemäß wird nun vorgeschlagen, bei Wärmeübertragungsvorrichtungen aus mehreren Gehäuseteilen im vom zu kühlenden Fluid durchströmten Kanal (3) unterbrochene Rippen (8) so anzuordnen, dass über den Querschnitt des vom zu kühlenden Fluid durchströmbaren Kanals (3) ein unterschiedlicher Abstand der Rippen (8) zueinander vorhanden ist, wodurch unterschiedliche Strömungswiderstände oder ungleichmäßige Anströmungen derart ausgeglichen werden sollen, dass über die gesamte Breite gleichmäßige Volumenströme geschaffen werden.
Hierdurch kann der Kühlerwirkungsgrad verbessert werden.
