Abstract: An apparatus includes a heat pipe, a first fin, and a second fin. The heat pipe includes a first end and a second end. The heat pipe defines a chamber through which a fluid flows. The first fin is coupled to the heat pipe at the first end. The first fin is arranged to absorb heat from the fluid at the first end such that the fluid at the first end flows back towards the second end. The second fin is coupled to the heat pipe between the first fin and the second end. The second fin is arranged to absorb heat from the fluid as the fluid flows from the second end towards the first end.
