Circuit

1. Introduction

Access to the “Cooling circuit” area is unlocked when a frame is defined, when its shape is circular or square.



How to unlock the “Fin” area ?
1 “Fin” area is unlocked (as well as the “Cooling circuit” area).
2 Selection of a circular shape frame.
3 Selection of a square shape frame.

2. Type of cooling circuits

The tools available in the housing tab allow defining the cooling circuit topology.

Four choices are available to define this topology: None, Zig-Zag, solenoid or User shape.

By default, fin type is set to “None”. There is no cooling circuit.



1

Default setting : Cooling circuit type is « None »

Theres is no cooling circuit inside the housing.

2 Button to select Zig-Zag type cooling circuit.
3 Button to select Solenoid type cooling circuit.
4 Button to select User type cooling circuit.
5 Icon to export fin data into *.txt or *.xls files.
