Description

히트싱크와 발열체가 탄성으로 밀착되는 방열장치Heat dissipation device in which heat sink and heating element are in elastic contact
본 발명은 다수의 히트싱크를 발열체에 면접촉시켜서 발열체의 열을 외부로 방출시키는 방열장치에 관한 것으로서, 보다 상세하게는 탄성을 이용해 히트싱크가 발열체에 보다 긴밀하게 밀착되고, 히트싱크 두께의 공차나 체결가이드 중앙부의 처짐 등에도 히트싱크가 흔들림 없이 발열체에 밀착되는 구조를 갖는 히트싱크와 발열체가 탄성으로 밀착되는 방열장치에 관한 것이다.The present invention relates to a heat dissipation device that discharges heat from the heating element to the outside by surface-contacting a plurality of heat sinks to the heating element. More specifically, the heat sink is more closely adhered to the heating element by using elasticity, and the tolerance of the heat sink thickness B. It relates to a heat sink having a structure in which the heat sink is in close contact with the heating element without shaking, even when the central portion of the fastening guide is sagging, and the like.
전기를 사용하는 전기전자 제품은 사용중에 열이 발생되고, 발생되는 열은 전기전자 제품에 악영향을 미쳐 효율을 저하시키고, 수명을 단축시키고, 심한 경우에는 고장을 일으켜 전기전자 제품의 구동을 중지시킨다.Electric and electronic products that use electricity generate heat during use, and the generated heat adversely affects the electric and electronic products, thereby reducing efficiency, shortening the lifespan, and in severe cases, causing malfunctions to stop the operation of electric and electronic products. .
그래서 대부분의 전기전자 제품에는 발생되는 열을 외부로 방출시키는 방열장치가 구비된다.Therefore, most electric and electronic products are equipped with a heat dissipation device that discharges the generated heat to the outside.
본 발명자는 전기전자 제품의 발열체에서 발생되는 열을 보다 효율적으로 외부로 방출시키기 위해 등록특허 제10-13895363호 "방열성을 향상시킨 방열장치"를 제안하였다. The present inventor has proposed a "heat dissipation device with improved heat dissipation" of Patent No. 10-13895363 in order to more efficiently discharge heat generated from a heating element of an electrical and electronic product to the outside.
상기 등록특허 제10-13895363호는 발열체와 면접촉되는 평판형의 'L'형 히트파이프 복수개와, 'L'형 히트파이프들과 발열체의 체결을 가이드하는 체결가이드를 통해 방열효율을 높이는 구조이다. The registered patent No. 10-13895363 is a structure to increase heat dissipation efficiency through a plurality of flat 'L' type heat pipes that are in surface contact with the heating element and a fastening guide that guides the connection of the 'L' type heat pipes and the heating element. .
히트파이프는 제조시의 공차에 의해 제품마다 두께가 조금씩 다를 수 있다. 그래서 상기 등록특허 제10-13895363호에서 많은 히트파이트는 두께의 미세한 차이로 일부는 발열체에 밀착되지 못한다. Heat pipes may differ slightly in thickness by product due to manufacturing tolerances. Therefore, in the registered patent No. 10-13895363, many heat pipes do not closely adhere to the heating element due to a slight difference in thickness.
그리고 체결가이드는 테두리가 있는 가장자리는 뒤틀리거나 쳐지는 등의 변형이 거의 없지만, 중앙부는 뒤틀리거나 쳐지기 쉽다. 뒤틀리거나 쳐지게 되면 그 부위의 히트싱크는 발열체에 제대로 접촉되지 못한다. In addition, the fastening guide has little deformation such as a warped or struck edge of the edge, but the central part is apt to be warped or struck. When warped or struck, the heatsink in the area cannot properly contact the heating element.
다시 말해, 종래기술에서는 공차, 쳐짐 등의 요인으로 히트파이프와 발열체가 긴밀하게 밀착되지 못하여 방열 효율이 떨어지고, 히트싱크가 흔들려 방열장치의 제품 안정성이 떨어지는 문제가 있다. In other words, in the prior art, due to factors such as tolerance and sagging, there is a problem in that the heat pipe and the heating element do not closely contact each other, so that the heat dissipation efficiency decreases, and the heat sink shakes, resulting in poor product stability of the heat dissipation device.
본 발명은 이처럼 종래기술에 따른 방열장치가 갖는 문제를 해결하기 위해 안출된 발명으로서, 체결가이드가 히트싱크를 발열체를 향해 탄성지지하여 밀어줌으로써 히트싱크와 발열체가 긴밀하게 밀착되고, 히트싱크 두께의 공차나 체결가이드의 쳐짐 등이 있어도 히트싱크가 흔들림 없이 발열체에 긴밀하게 밀착되어 방열효율이 뛰어나고, 체결불량이 발생하지 않는 히트싱크와 발열체가 탄성으로 밀착되는 방열장치를 제공함을 목적으로 한다. The present invention is an invention devised to solve the problems of the heat dissipation device according to the prior art, and the heat sink and the heat generating element are in close contact with each other, and the heat sink is in close contact with the coupling guide by elastically supporting and pushing the heat sink toward the heating element. It is an object of the present invention to provide a heat dissipation device in which the heat sink is in close contact with the heating element without shaking and has excellent heat dissipation efficiency even when there is a tolerance or sagging of the fastening guide, and the heat sink and the heat generating element that do not cause a defective connection are elastically close.
