网页In conventional representation, thermal conductivity, k, is usually thought to be an intrinsic material property, i.e., k is often treated as a constant. In this case, the rate of heat conduction Q ˙ can be scaled as Q ˙ ∝ l 2 ·l −1 =l from Eq. (3.43).It implies that a reduction in size leads to a decrease in the total heat conduction within a unit time.
