<p>HEAT SINK BY EXTRUSION FOR REGULATOR RECTIFIER Abstract The present invention relates to an extruded heat sink mounted in a movable body and exposed to a traveling air stream generated while the movable body moves, includes a base and a heat dissipating portion having a plurality of fins. Plurality of fins is arranged apart from each other and extends from a base in longitudional direction to a flow of travelling air stream. At least in a front end portion of the heat dissipating portion, the heat dissipating portion includes a rectifying portion provided so as to extend across a predetermined area in a longitudinal direction in front portions of slit-shaped flow paths at an upstanding end (i.e., an end apart from the base). The present embodiment reduces the size of the regulator rectifier by 40%.</p> |
