Heat Transfer: Exercises 9 Introduction Example 1 4 An electronic component dissipates 0 38 Watts through a heat sink by convection and radiation (black body) into surrounds at 20oC What is the surface temperature of the heat sink if the convective heat transfer coefficient is 6 W/m2 K, and the heat sink has an effective area of 0 001 m2




[PDF] Heat Transfer conduction and convection

book is primarily concerned with convective heat transfer Essentials of mass transfer are also covered The mass transfer material and prob-lems are presented such that they can be easily skipped, should that be preferred The book is richly enhanced by exercises and end-of-chapter problems Solutions are available for quali?ed instructors
