HEAT SINK ASSEMBLY
A heat sink assembly. The heat sink assembly includes a heat sink plate having a planar body part with an inclined wall formed in a central portion thereof and a plurality of heat sink fins each extending from the wall towards an edge portion of the body part while protruding perpendicularly to the body part, and a housing disposed below the heat sink plate and having an accommodation section accommodating the heat sink fins and a heat-outlet bent downwardly along a peripheral side of the accommodation section.
1 . A heat sink assembly comprising:
a heat sink plate having a planar body part with an inclined wall formed in a central portion thereof and a plurality of heat sink fins each extending from the wall towards an edge portion of the body part while protruding perpendicularly to the body part; and
a housing disposed below the heat sink plate and having an accommodation section accommodating the heat sink fins and a heat-outlet bent downwardly along a peripheral side of the accommodation section.
2 . The heat sink assembly according to claim 1 , wherein the heat sink fins are arranged in a radial pattern.
3 . The heat sink assembly according to claim 1 , wherein the inclined wall has a downwardly convergent inclined shape.
4 . The heat sink assembly according to claim 1 , wherein the accommodation section has a first opening in a region corresponding to the wall between the heat sink fins, and wherein the heat-outlet has a second opening in a region corresponding to the body part between the heat sink fins.
5 . The heat sink assembly according to claim 1 , wherein the housing further has an extension portion extending outwardly from the accommodation section.
6 . The heat sink assembly according to claim 1 , wherein the wall has a width greater than a height thereof.
7 . The heat sink assembly according to claim 1 , wherein circuit elements are disposed above the heat sink plate, wherein the width of the wall is less than a length of the circuit elements.
8 . The heat sink assembly according to claim 1 , further comprising a heat sink fan disposed in the housing so as to be separate from the heat-outlet and the accommodation section.
9 . The heat sink assembly according to claim 8 , further comprising a motor winding disposed between the heat-outlet and the heat sink fan so as to be separate from the accommodation section and partially exposed through the second opening.
10 . The heat sink assembly according to claim 9 , wherein a distance between the accommodation section and the motor winding is smaller than a distance between the accommodation section and the heat sink fan.
