DELPHI modelling in Celsius Thermal Solver

In DELPHI modeling, you specify parameters for the DELPHI thermal model network of the component, and the tool will model the heat transfer inside the component according to these thermal parameters.

Following steps will help you implement DELPHI model for static analysis:

1. Right-click the design canvas in the Layoutpane and choose Select > Solids from the context menu.       

        2. Click to select the object to which you want to apply the component thermal model and right-click and choose Component Thermal Model> DELPHI Model from the context menu.

The Static DELPHI Model window displays.

3. To add internal nodes for the DELPHI model, right-click in the Internal Nodes canvas area and select Add from the context menu.

Specify a Name and Power (W) value for the node and click OK.

4. To add external nodes for the DELPHI model, right-click in the External Nodes area and select Add from the context menu.

Select the external node type from the Name dropdown list. This selection defines how the external node corresponds to the physical areas on the actual package. Now, specify a Power (W) and Area (mm²) value of the external node and click OK.

5. After you have added internal and external nodes, add network connections between these nodes. To do this, right-click in the Network Connection area of the Static DELPHI modelwindow and select Add from the context menu.

Select the nodes to be connected from the Node1 and Node2 dropdown lists and specify the thermal resistance between these nodes in the Resistance (C/W) field. Click OK.

6. Click OK to close the Static DELPHI Model The DELPHI model is added to the Project pane and its properties appear in the Property pane as shown below.

These steps show how to model a DELPHI thermal model in Celsius. For more information on DELPHI modelling, you can refer here .
