A removable heatsink assembly adapted to removably receive a pipe. The removable heatsink assembly includes a first plurality of fins and a second plurality of fins having collar flanges sized to receive a pipe. The fins are received on first and second spacer rods, respectively and are hingedly connected by a hinge rod such that the first and second plurality of fins are pivotally movable about the hinge rod between an open position and a closed position. In the open position, the first and second plurality of fins are positionable over the pipe. In the closed position, the collar flanges of the first and second plurality of fins substantially surround the pipe. A fin clamp secures the first and second plurality of fins together in the closed position about the pipe.
