Why do copper coatings have higher power density than heat sinks?

For example, our experiments show that although a heat sink and the 223-µm-thick Cu coating have similar thermal resistances, the power per unit volume of the copper coating is 740% higher than that of the heat sink. This increase in power density is due to an 89% decrease in the volume occupied by the coatings relative to that of the heat sink.
