Patent ID: 7675752

Claim:
An electronic apparatus comprising: a housing; a first exothermic component in the housing; a heat pipe thermally connected to the first exothermic component; and a heat sink in the housing penetrated by the heat pipe, wherein the heat sink comprises a first fin structure and a second fin structure, the first fin structure comprises a plurality of fins located at intervals, and the fins of the first fin structure comprise a through-hole in which the heat pipe is inserted and a caulking margin portion extending from an edge portion of the through-hole along a circumferential surface of the heat pipe and fixed to the heat pipe, the second fin structure comprises a plurality of fins located at intervals, the fins of the second fin structure are located in spaces between the fins of the first fin structure, and configured to overlap the heat pipe in the first fin structure, and the fins of the second fin structure comprise a cutout portion configured to allow the heat pipe through, the cutout portion of the fins of the second fin structure is larger than the outer shape of the caulking margin portion of the fins of the first fin structure, and the fins of the second fin structure are configured to overlap with the caulking margin portions of the fins of the first fin structure.
