Fin with elongated hole and heat pipe with elongated cross section

A heat pipe assembly, comprising:

• a heat pipe having an envelope, the envelope having two elongated flat sides and two curved portions connecting the flat sides, the elongated sides having a length that is substantially greater than a radius of curvature of the curved portions;
• and
• at least one fin comprising a plate, the plate having a hole therethrough that is sized to accommodate the envelope, the hole having two elongated flat sides and two curved portions connecting the flat sides, the elongated sides having a length that is substantially greater than a radius of curvature of the curved portions, the plate having at least one collar portion adjacent to the hole, the collar portion extending approximately in a direction normal to the plate.

A fin comprising a plate wherein said plate has a hole defined therethrough, said hole having two elongated flat sides and two curved portions connecting the flat sides, the elongated sides having a length that is substantially greater than a radius of curvature of the curved portions, said plate having at least one collar portion adjacent to the hole, the collar portion extending approximately in a direction normal to said plate, wherein the plate has at least two collar portions, separated from one another by a plurality of slots.
