A coiled metallic wire is made flat to make adjacent ring units (11a, 11b) of the coil in close contact with each other, and thus a fin (11) is formed. Fins (11) are arranged such that flat surfaces (111) of the fins are perpendicular to a heat conductive substrate (10) to form a heat sink (1). Thus the heat sink can be produced at low cost and efficiently. A novel heat sink excellent also in heat radiation ability can be provided.
Selon la présente invention, un fil métallique en spirale est aplati de manière à placer les unités de bague adjacentes (11a, 11b) de la spirale en contact étroit les unes avec les autres, afin de former une ailette (11). Les ailettes (11) sont disposées de manière que leurs surfaces planes (111) soient perpendiculaires à un substrat conducteur de chaleur (10), afin de former une source de froid (1). Cette invention permet ainsi de produire de manière économique et efficace une source de froid qui présente une très bonne capacité de rayonnement de la chaleur.
