There is a heat sink 3 as one radiating means.

히트싱크(3)는 열방출 효율이 양호한 알루미늄금속재로 형성되고 있으며, 수많은 방열편(3a)을 구비한다.The heat sink 3 is made of an aluminum metal material having good heat dissipation efficiency, and includes a large number of heat dissipation pieces 3a.

도시된 바와 같이, 본 고안에 따른 발열회로소자용 방열장치는, 회로기판에 설치된 다수의 부품중 발열회로소자는 고정플레이트와 히트싱크의 내장공에 삽입된후에, 회로기판에 고정되는 구조를 가진다.As shown, the heat dissipation device for a heating circuit device according to the present invention, the heating circuit device of the plurality of components installed on the circuit board has a structure that is fixed to the circuit board after being inserted into the internal hole of the fixing plate and the heat sink. .

여기에서, 회로기판(10)은 제품 내부에 설치되는 것으로서, 히트싱크(30)를 충분히 설치할만한 면적을 갖고 있다.Here, the circuit board 10 is provided inside the product, and has an area enough to install the heat sink 30.

발열회로소자(20)는 주로 트랜지스터와 같은 회로부품이며, 하부에 회로기판(10)에 설치되는 다수의 접속핀(21)을 구비하고 있다.The heating circuit device 20 is mainly a circuit component such as a transistor, and has a plurality of connection pins 21 provided at the bottom of the circuit board 10.

그리고 히트싱크(30)는, 대략 박스체 형상으로 중앙에 발열회로소자(20)가 관통되는 내장공(31)이 형성되고, 양측에는 다수의 방열편(32)이 돌출 형성된다.The heat sink 30 is formed in a substantially box-like shape with a built-in hole 31 through which the heat generating circuit element 20 penetrates, and a plurality of heat dissipation pieces 32 protrude from both sides.

또한, 내장공(31)은 양측에 수직돌기편(33)을 형성시키므로써 협소공간부(34)를 형성하도록 되어있다.In addition, the built-in hole 31 is to form a narrow space portion 34 by forming the vertical projection piece 33 on both sides.

가압수단인 고정플레이트(40)는, 히트싱크(30)의 내장공(31) 내면에 밀착되는 주면판부(41)와, 주면판부(41)에서 탄성을 갖도록 돌출되어 발열회로소자(20)를 가압하는 누름스프링부(42)와, 하측에 구비되고 회로기판(10)에 고정되는 고정부(43)를 포함한다.The fixing plate 40, which is a pressing means, protrudes from the main surface plate portion 41, which is in close contact with the inner surface of the internal hole 31 of the heat sink 30, and protrudes elastically from the main surface plate portion 41. And a pressing spring portion 42 for pressing, and a fixing portion 43 provided below and fixed to the circuit board 10.

또한, 고정부(43)는 회로기판(10)의 결합공(11)을 관통하여 걸림되는 결합턱부(44)를 구비하고, 고정부(43)는 회로기판(10)에 납땜되어 솔더링부(45)를 갖도록 되어 있다.In addition, the fixing part 43 includes a coupling jaw portion 44 that is engaged through the coupling hole 11 of the circuit board 10, and the fixing part 43 is soldered to the circuit board 10 to be soldered. 45).

그리고, 고정플레이트(40)는 주면판부(41) 상측 양쪽에 히트싱크(30)의 상단부에 걸림되는 걸림턱부(46)를 구비하고, 일측에는 히트싱크(30)의 협소공간부(34)에서 주면판부(41)가 억지끼움 되도록 하는 돌륜부(47)가 돌출 형성된다.In addition, the fixing plate 40 includes a locking jaw portion 46 that is engaged on the upper end of the heat sink 30 on both sides of the main surface plate portion 41, and at one side of the narrow space portion 34 of the heat sink 30. The protrusion wheel part 47 which protrudes the main surface plate part 41 is formed.

상기와 같은 본 고안에 따른 발열회로소자용 방열장치의 작용을 제5(a)도 내지 제5(c)도를 참조하여 간략하게 설명하면 다음과 같다.The operation of the heat dissipating device for the heating circuit device according to the present invention as described above will be briefly described with reference to FIGS. 5 (a) to 5 (c).

제5(a)도 및 제5(b)도에 도시된 바와 같이 발열회로소자(20) 및 고정플레이트(40)를 히트싱크(30)의 내장공(31)에 포개지도록 삽입시킨다. 이때 먼저 발열회로소자(20)를 삽입시키고 고정플레이트(40)를 이어서 삽입시키거나, 이것과 반대로도 삽입시킬 수도 있다.As shown in FIGS. 5 (a) and 5 (b), the heating circuit device 20 and the fixed plate 40 are inserted so as to overlap the internal holes 31 of the heat sink 30. In this case, the heating circuit device 20 may be inserted first, and then the fixing plate 40 may be inserted subsequently, or vice versa.

발열회로소자(20)와 고정플레이트(40)를 겹치게 하여 내장공(31)에 삽입하여도 무관한 것으로, 이러한 삽입방법은 작업자의 편리에 따라서 실시된다.The heating circuit device 20 and the fixed plate 40 may overlap each other and may be inserted into the internal hole 31. This insertion method may be performed according to the convenience of the operator.

그러나 상기와 같은 삽입과정에 반드시 해야 할 것은 고정플레이트(40)의 누름스프링부(42)가 발열회로소자(20)를 가압할 수 있도록 상호 밀착되는 상태로 내장되게 하는 것이다.However, it is essential to the insertion process as described above is that the pressing spring portion 42 of the fixing plate 40 is to be embedded in a state in close contact with each other so as to press the heat generating circuit element 20.

따라서, 발열회로소자(20)는 내장공(31) 내부에서 누름스프링부(42)의 가압력에 의해 이탈되지 않도록 고정된다.Therefore, the heating circuit device 20 is fixed so as not to be separated by the pressing force of the pressing spring portion 42 in the interior hole (31).

그리고 발열회로소자(20)를 고정시키는 고정플레이트(40)는 삽입과정에 걸림턱부(46)가 히트싱크(30)의 상단부에 걸림되어 내장공(31)의 하부로는 고정부(43)만이 노출되는 상태로 설치되게 되고, 이와 동시에 돌륜부(47)는 히트싱크(30)의 협소공간부(34)에 위치하는 상태로 억지끼움됨으로 고정플레이트(40)에 외력을 가하여 잡아 빼지 않는 한 히트싱크(30)로부터 이탈되지 않게 된다.In addition, the fixing plate 40 for fixing the heating circuit device 20 has the locking jaw portion 46 caught by the upper end of the heat sink 30 during the insertion process, so that only the fixing portion 43 is disposed below the built-in hole 31. It is installed in an exposed state, and at the same time, the wheel wheel portion 47 is fitted in the state of being located in the narrow space portion 34 of the heat sink 30, so that the heat is applied to the fixing plate 40 without being pulled out. The sink 30 is not separated.

그러므로 히트싱크(30)의 내장공(31)에 고정플레이트(40)와 발열회로소자(20)가 고정되도록 설치된 상태에서 히트싱크(30)를 취급하여도 이들은 분리되지 않게 되므로 작업을 수월하게 한다.Therefore, even if the heat sink 30 is handled in a state where the fixing plate 40 and the heating circuit device 20 are installed in the built-in hole 31 of the heat sink 30, they are not separated, thereby facilitating the work. .

결과적으로, 고정플레이트(40)에 의해 히트싱크(30)에 발열회로소자(20)가 히트싱크(30)에 고정된 상태로서 회로기판(10)에 고정되도록 할 수 있다.As a result, the heat generating circuit device 20 is fixed to the heat sink 30 by the fixing plate 40 so as to be fixed to the circuit board 10.

이때, 고정플레이트(40)의 고정부(43)는 회로기판(10)의 결합공(11)으로 삽입되도록 하는 동시에 발열회로소자(20)의 접속핀(21)은 핀공(12)으로 삽입되도록 한다.In this case, the fixing part 43 of the fixing plate 40 is inserted into the coupling hole 11 of the circuit board 10 and the connection pin 21 of the heating circuit device 20 is inserted into the pin hole 12. do.

그에 따라, 고정부(43)의 결합턱부(44)는 결합공(11)을 관통하여 이탈되지 못하도록 걸림되어 고정플레이트(40)를 임시 고정한다.Accordingly, the coupling jaw portion 44 of the fixing portion 43 is locked so as not to be separated through the coupling hole 11 to temporarily fix the fixing plate 40.

결합공(11) 및 핀공(12)으로 관통된 고정부(43)와 접속핀(21)을 납땜하여 솔더링부(45)를 형성하여, 고정플레이트(40)를 완전히 고정하게 되는 것이다.The soldering part 45 is formed by soldering the fixing part 43 and the connecting pin 21 penetrated by the coupling hole 11 and the pin hole 12 to completely fix the fixing plate 40.

상기와 같이 본 고안은 발열회로소자(20)가 히트싱크(30)의 내장공(31)의 일측 내면에 밀착되므로써 양호한 열전달이 되지만 다른 일측면은 고정플레이트(40)와 접촉되는 상태가 된다.As described above, according to the present invention, the heat generating circuit element 20 is in close contact with the inner surface of one side of the internal hole 31 of the heat sink 30, thereby providing good heat transfer, but the other side surface is in contact with the fixing plate 40.

그러므로 양호한 열전달을 위해 고정플레이트(40)는 인청동재질로 형성되도록 하는 것이 바람직하고, 히트싱크(30)는 기존과 같이 알루미늄재질로 형성됨으로써, 열전달과 열방출이 도모되는 것이다.Therefore, for good heat transfer, the fixed plate 40 is preferably formed of a phosphor bronze material, and the heat sink 30 is formed of an aluminum material as in the prior art, so that heat transfer and heat dissipation are promoted.

이상의 설명에 따르면, 본 고안에 다른 발열회로소자용 방열장치는 발열회로소자, 히트싱크, 고정플레이트를 단순히 조립시켜서 회로기판에 설치하는 함으로, 기존과 같은 별도의 공구 사용없이도 설치 가능하기 때문에 수월한 작업이 할 수 있고, 이와 동시에, 작업능률 및 생산성 향상을 도모할 수 있다.According to the above description, the heat dissipating device for a heat generating circuit element according to the present invention is simply installed by assembling the heat generating circuit element, heat sink, and fixing plate on a circuit board, and thus can be installed without using a separate tool as in the past. This can be done, and at the same time, work efficiency and productivity can be improved.

또한, 발열회로소자의 양면이 직,간접적으로 히트싱크와 열전달이 될 수 있도록 접촉되므로 열전달면적 증대에 따른 열방출 효율의 향상을 도모할 수 있다.In addition, since both sides of the heat generating circuit element are directly and indirectly contacted to allow heat transfer with the heat sink, the heat dissipation efficiency can be improved by increasing the heat transfer area.
