Abstract

A flow channel for a heat exchanger for exchanging heat between a first fluid and a second fluid, the flow channel having, perpendicular to a flow channel axis, a cross-section that can be traversed, the flow channel providing for an improved transfer of heat with an acceptable drop of pressure and a reduced risk of blocking. The flow channel has a hydraulic diameter, defined as quadruple the ratio between the surface of the cross-section that is traversed and the perimeter that can be moistened by the fluid, of between 1.5 mm and 6 mm. Also a heat exchanger having a plurality of flow channels of this type, through which the first fluid flows and fluidically connected by a fluid connection. Also a charge-air system and an exhaust gas recycling system having such flow channels.
