Conduction and Convection

When energy travels from one object to another it is said to have undergone heat transfer. Heat transfer is nothing but the transfer of thermal energy or internal energy from one thing to another, like e.g., when a vessel with water, kept on top of a burner, heats up because of the flame underneath it.

Example 2.10 Consider a 25 mm x 25 mm x 1 mm thick silicon die attached to a same size 2 mm-thick copper cap through a 0.1 mm thick thermal interface material (TIM) as shown in Figure 2.1. Convection heat transfer coefficient on the top side of the copper cap is 2500 W/m²°C. If thermal conductivity of silicon, copper, and thermal interface material are 125, 390, and 5 W/m°C, respectively, what is the total thermal resistance from the active (bottom) side of the silicon die to outside ambient?

A plane wall of an oven with an insulation coating is attached to an insulated wall. The thermal conductivity and thickness of the insulation coating are 0.1 W/(m K) and 1 mm, respectively. The material of the plane wall is stainless steel 304. The density, thermal conductivity, and specific heat capacity of the stainless steel 304 are 7900 kg/m³, 74.9 W/(mK), and 477 J/(kg-K), respectively. The wall thickness of the stainless steel 304 is 15 mm. The temperature of the plane wall with the insulated coating is initially maintained at 30 °C.
