您的练习:打开PLECS模型"thermal_domain_start.plecs",并在电路中添加散热器(Heat Sink)、热敏电阻(Thermal Resistor)和恒温接地块(Constant Temperature (Grounded)),如图1所示。这些组件可以在PLECS组件库的热部分找到(Thermal)。这些组件的参数如下所示:
colder surface, determined as the heat energy transferred per unit of time and per unit of surface area divided by the temperature gradient, which is the temperature difference divided by the distance between the two surfaces (the thickness of the material), expressed in watts per kelvin per ...
The thermistor’s role in this circuit is the upper resistor in a voltage divider. In this case, you’d want to use a thermistor with a negative temperature coefficient; one whose resistance decreases as temperature increases. As that upper resistance decreases, the divided voltage rises, eventua...

They are further coupled in series, with the conduction resistors corresponding to the three structural layers, which are denoted by R1, R2, R3, and eventually to the convective resistor Rconv,o. The equivalent thermal resistance is therefore: (5.123)Req=Rconv,i·RradRconv,i+Rrad+R1+R2+R3+...
