The present invention relates to a top plate type heat dissipation fin forming tool assembly, capable of forming a heat dissipation fin having a flat surface on a valley and a mountain portion of the heat dissipation fin to increase a contact area with a tube of a heat exchanger, comprising: a first tool unit including a pair of first cover members each having a first louver non-formed portion on an outer circumferential surface thereof, first unit forming tools installed between the first cover members and having first serrated forming portions on an outer circumferential portion of a first body part of a disk and first and second louver formed portions formed on both sides of the first forming portions, and a first coupling part coupling the first cover members and the first unit forming tools; and a second tool unit coupled to the first tool unit to form the heat dissipation fin and including a pair of second cover members each having a second louver non-formed portion on an outer circumferential surface thereof, second unit forming tools installed between the second cover members having second serrated forming portions on an outer circumferential portion of a second body part of the disk and third and fourth louver formed portions prepared on both sides of the second forming portions, and a second coupling part coupling the second cover members and the second unit forming tools. A first lead portion and a first protrusion portion are formed in a vertex portion of the mountain portion and a vertex portion of the valley portion of the first forming part, and a second protrusion portion coupled to the first lead portion and a second lead portion coupled to the first protrusion portion are formed in the valley and mountain portions of the second forming part and coupled to each other to form a flat surface of the vertex portions of the maintain and valley portions when the heat dissipation fin is formed. 본 발명의 탑 플레이트 타입 방열핀 성형툴조립체는 외주면에 제1루버미성형부를 가지는 한쌍의 제 1커버부재들과, 상기 제 1커버부재들의 사이에 설치되며 디스크상의 제1본체부 외주부에 톱니형의 제1성형부들이 형성되고, 제 1성형부의 양측면에 제 1,2루버형성부가 형성된 제1단위성형툴들과, 상기 제1커버부재들과 제1단위성형툴들을 상호 결합하는 제 1결합부를 포함하는 제1툴유닛과; 상기 제1툴유닛와 결합되어 방열핀을 성형하는 것으로, 외주면에 제2루버미성형부를 한쌍의 제 2커버부재들과, 상기 제 1커버부재들의 사이에 설치되며 디스크상의 제 2본체부 외주부에 톱니형의 제2성형부들이 형성되고, 제 2성형부의 양측면에 제 3,4루버형성부가 마련된 제2단위성형툴들과, 상기 제2커버부재들과 제2단위성형툴들을 상호 결합하는 제 2결합부를 포함하는 제2툴유닛;을 구비하며, 상기 제 1성형부의 산부 정점부위와 골의 정점부위에는 제1인입부와 제 1돌기부가 형성되고, 상기 제 2단위성형툴을 구성하는 제 2성형부의 골과 산부위에 제1인이부와 결합되는 제2돌기부와 상기 제 1돌기부와 결합되는 제 2인입부가 형성되어 상호 결합됨으로써 방열핀의 성형 시 산부와 골의 정점부위에 평활면을 형성하는 탑플레이트형성부를 포함한다.
