Materials used in heat sink should have_____________?
Correct answer: D. All of these
- A. high thermal conductivity
- B. large surface area
- C. high melting point
- D. All of these
Explanation
A practical heat sink needs good thermal conductivity and a large exposed area to transfer heat to the air; a high melting point also provides thermal robustness. Thus all the listed properties are desirable.
