Thermal Port

Purpose

Add thermal connector to subsystem

Library

Thermal / Connectivity

Description

Thermal ports are used to establish thermal connections between a schematic and the subschematic of a Subsystem. If you copy a Thermal Port block into the schematic of a subsystem, a terminal will be created on the subsystem block. The name of the port block will appear as the terminal label. If you choose to hide the block name by unselecting the show button in the dialog box, the terminal label will also disappear.

A terminal can be moved around the edges of the subsystem by dragging it with the middle mouse button. Alternatively, use the left mouse button while holding the Shift key.

Thermal Ports in a Top-Level Schematic

In PLECS Blockset, if a Thermal Port is placed in a top-level schematic, the PLECS Circuit block in the Simulink model will show a corresponding thermal terminal, which may be connected with other thermal terminals of the same or a different PLECS Circuit block. The Thermal Port is also assigned a unique physical port number. Together with the parameter Location on circuit block the port number determines the position of the thermal terminal of the PLECS Circuit block.

For compatibility reasons you can also place a Thermal Port in a top-level schematic in PLECS Standalone. However, since there is no parent system to connect to, such a port will act like an isolated node.

Note

Thermal Port blocks may not be used in schematics that contain Ambient Temperature blocks.

Parameters

Port number

If a Thermal Port is placed in a top-level schematic in PLECS Blockset, this parameter determines the position, at which the corresponding terminal appears on the PLECS Circuit block.

Location on circuit block

If a Thermal Port is placed in a top-level schematic in PLECS Blockset, this parameter specifies the side of the PLECS Circuit block on which the corresponding terminal appears. By convention, left refers to the side on which also input terminals are shown and right refers to the side on which also output terminals are shown.
