Parallel Thermal Resistance in composite walls (conduction)
Thermal resistance is a heat property and a measurement of a temperature difference by which an object or material resists a heat flow. Thermal resistance is the reciprocal of thermal conductance.
The absolute thermal resistance R in K/W is a property of a particular component. For example, a characteristic of a heat sink.
The thermal resistance of materials is of great interest to electronic engineers because most electrical components generate heat and need to be cooled. Electronic components malfunction or fail if they overheat, and some parts routinely need measures taken in the design stage to prevent this.
The Parallel Thermal Resistance in composite walls is calculated as shown.Related formulas
