Controlled Temperature Source

Variable source of thermal energy, characterized by temperature

  • Controlled Temperature Source block

Simscape / Foundation Library / Thermal / Thermal Sources


The Controlled Temperature Source block represents an ideal source of thermal energy that is powerful enough to maintain specified temperature difference across the source regardless of the heat flow consumed by the system.

Connections A and B are thermal conserving ports corresponding to the source inlet and outlet, respectively. Port S is a physical signal port, through which the control signal that drives the source is applied. You can use the entire variety of Simulink® signal sources to generate the desired heat flow variation profile. The temperature differential across the source is directly proportional to the signal at the control port S.

The block positive direction is from port A to port B. This means that the temperature differential is determined as TBTA, where TB and TA are the temperatures at source ports.
