HEAT SINK

PROBLEM TO BE SOLVED: To provide a heat sink capable of saving redundant man-hours for change of design or the like, and reducing a manufacturing cost by enabling an electric component such as an LED to be appropriately cooled even if its heat generating amount increases. SOLUTION: The heat sink 10...

description	PROBLEM TO BE SOLVED: To provide a heat sink capable of saving redundant man-hours for change of design or the like, and reducing a manufacturing cost by enabling an electric component such as an LED to be appropriately cooled even if its heat generating amount increases. SOLUTION: The heat sink 10 includes a platelike base 1 rectangular in a plan view as a heat dissipating substratum, a plurality of fins 2 detachably attached to the base 1, and a plurality of auxiliary fins 3 detachably attached to the fins 2. A plurality of linear grooves 1a are formed to be parallel to one another on the lower surface of the base 1. The groove 1a is formed in a T-shaped cross section. A T-shaped protrusion 2b which can fit with the groove 1a formed on the base 1 is formed at one end of the fin 2. A groove 2a is formed in a longitudinal direction on a barrel of the fin 2 with a T-shaped cross section. A T-shaped protrusion 3b which can fit with the groove 2a of the fin 2 is formed at an end of the auxiliary fin 3. COPYRIGHT: (C)2008,JPO&INPIT
