WebJul 18, 2024 · $$ \bar{C}_p = \bar{C}_V + R$$ $$ \Delta U \equiv n\bar{C}_V\Delta T \ \ \ \ \Delta H \equiv n\bar{C}_p\Delta T $$ The first expression is always true of an ideal gas. The latter two expressions are always true for an ideal gas with a constant specific heat capacity regardless of whether the path taken is reversible or irreversible. Absolute thermal resistance is the temperature difference across a structure when a unit of heat energy flows through it in unit time. It is the reciprocal of thermal conductance. The SI unit of absolute thermal resistance is kelvins per watt (K/W) or the equivalent degrees Celsius per watt (°C/W) – the two are the … See more 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. • (Absolute) … See more The junction-to-air thermal resistance can vary greatly depending on the ambient conditions. (A more sophisticated way of expressing the same fact is saying that junction-to-ambient thermal resistance is not Boundary-Condition Independent (BCI). ) See more • Thermal engineering • Thermal design power • Safe operating area See more • Guoping Xu (2006), Thermal Management for Electronic Packaging, Sun Microsystems • See more Electrical engineers are familiar with Ohm's law and so often use it as an analogy when doing calculations involving thermal resistance. Mechanical and structural engineers are more … See more Resistances in series When resistances are in series, the total resistance is the sum of the resistances: See more There is a large amount of literature on this topic. In general, works using the term "thermal resistance" are more engineering-oriented, whereas works using the term thermal conductivity are more [pure-]physics-oriented.
