PURPOSE: A cooling apparatus is provided to improve a heatproof efficiency by increasing a surface area. CONSTITUTION: A cooling apparatus(160) comprises a plate, a plurality of perpendicular pillar(164) extended with a same interval on the plate, a dummy plate(162) covering the perpendicular pillar, and a plurality of protrusion part(166) protruded from each of a bottom surface of the plate and both surfaces of the perpendicular pillars. The each of the perpendicular pillars is extended with perpendicular and with a zigzag type on the plate. An intelligent Power Module(IPM)(142) is equipped at a rear surface of the plate. The dummy plate is set up at a front surface of the perpendicular pillars to intersect with a same spacing about the perpendicular pillars and covers a center part of the perpendicular pillar except for an edge of the perpendicular pillars. |
