Description
The Heat Flow Rate Source block represents an ideal source of thermal energy that is powerful enough to maintain specified heat flow at its outlet regardless of the temperature difference across the source.
The source generates constant heat flow rate, defined by the Heat flow rate parameter value.
Examples
Engine Cooling System
Model a basic engine cooling system using custom thermal liquid blocks. A fixed-displacement pump drives water through the cooling circuit. Heat from the engine is absorbed by the water coolant and dissipated through the radiator. The system temperature is regulated by the thermostat, which diverts flow to the radiator only when the temperature is above a threshold.

Parameters
Programmatic Use: Add Block
To add the block programmatically, use the add_block function with one of these library block paths as the source.
"fl_lib/Thermal/Thermal Sources/Heat Flow Rate Source"
Example: add_block("fl_lib/Thermal/Thermal Sources/Heat Flow Rate Source","myModel/myBlock",MakeNameUnique="on")
For information about programmatic access to individual block parameters, see the Programmatic Use section of parameter descriptions on this page.
