1. A heat sink comprising:
a plurality of heat pipes; and
a plurality of extrusions that are aligned in a width direction orthogonal to an extrusion direction and joined to each other; wherein
the plurality of extrusions comprise a plurality of first extrusions each having a first base, a first fin that protrudes from the first base, and a through-hole in which one of the plurality of the heat pipes is mountable in the first base,
the through-hole extends in the extrusion direction,
each of the plurality of heat pipes is mounted in a respective through-hole, and
the plurality of first extrusions is arranged in either a first configuration or a second configuration, such that distances between the adjacent through holes are not constant,
wherein in the first configuration the plurality of extrusions further comprise a plurality of second extrusions each having a second base, a second fin that protrudes from the second base, and a width dimension different from a width dimension of the plurality of first extrusions, the distances between the adjacent through-holes are adjusted by arrangements of the plurality of second extrusions, and the first extrusions and the second extrusions are joined to each other in the width direction by a brazing material arranged between side surfaces of the first extrusion and the second extrusion, and
wherein in the second configuration plurality of first extrusions is comprised by a plurality of types of first extrusions having different width dimensions, the distances between adjacent through-holes are adjusted by arrangements of the plurality of types of first extrusions, and the plurality of types of first extrusions are joined to each other in the width direction by a brazing material arranged between a side surface of the plurality of types of first extrusions.
