Selection guide

The following selection guide is only an estimate of the passive cooling of your housing. However, location, components and system-specific features of your system can significantly affect this assessment. An effective and optimal heat dissipation concept requires a consideration of all relevant system parameters. We can do it for you.

Abschätzung der passiven Entwärmungsleistung Estimation of passive heat dissipation	QK = k x A x ΔT
QK: Passive Entwärmungsleistung [W]	QK: Passive heat dissipation [W]
k: Wärmedurchgangskoeffizient [W/(m²K)]	k: heat transfer coefficient [W/(m²K)]
abhängig von Material, Wandstärke, Strömung	depends on material, wall thickness, air flow
Material	Material
Stahl 4,5 – 5,5 [W/(m²K)]	Steel 4,5 – 5,5 [W/(m²K)]
Edelstahl 3 – 4 [W/(m²K)]	Stainless steel 3 – 4 [W/(m²K)]
Aluminium 3,5 – 12 [W/(m²K)]	Aluminium 3,5 – 12 [W/(m²K)]
