The convective heat transfer is strongly dependent on both the flow type and the fluid flow character as well as the geometric configuration of the solid body.

In this context, when the similarity theory and dimensional (criteria) analysis are applied, the convective heat exchange between the inner surface of the radiator cooling channel.

With regard to heat sources, the calculation model considered was reduced to – arranged on the outer radiator surface (on the side intended for mounting semiconductor elements) – the regions representing the radiator semiconductor module transition zone.

The simulation calculations presented above demonstrate that with the use of the software for field heat transfer calculations, it is also possible to effectively analyse more complex problems.

A engineering solution live calculations is the professionally presented document. Unit conversion, and powerful calculation capabilities, presented within the familiarity of an engineering solutions, allow engineers and design teams to more easily communicate critical design and engineering knowledge. As a result of using dedicated engineering math software teams avoid the majority of errors.
