描述
Controlled Heat Flow Rate Source 模块表示理想的热能源，无论该热能源两端的温差多大，它都足以在其出口处维持指定的热流。
连接端 A 和 B 是分别对应于源入口和出口的热守恒端口。端口 S 是物理信号端口，通过该端口应用驱动该源的控制信号。您可以使用各种 Simulink® 信号源来生成所需的热流变化曲线。通过源的热流与控制端口 S 处的信号成正比。
此模块的正方向是从端口 A 到端口 B。这意味着端口 S 处的正信号会产生从 A 到 B 方向的热流。
示例
Heat Conduction Through Iron Rod
How thermal blocks can model a long iron rod that is fixed to a hot base at one end and exposed to air along its length and at its free end. The rod is an extended surface that undergoes conduction along its length and convection with air in the direction perpendicular to its length. Extended surfaces are often used as fins to cool a solid.
