본 발명은 엘이디(LED; Light Emitting Diode)조명 등에서 발생하는 열을 외부로 발산시키기 위한 방열체에 관한 것으로서, 각각이 별도로 형성되는 방열핀을 베이스에 조립하여 방열체를 제작함으로써 다양한 크기 및 형상의 방열체를 쉽게 제작할 수 있다는 특징을 갖는다.The present invention relates to a heat sink for dissipating heat generated from LED (Light Emitting Diode) light to the outside, by assembling the heat radiation fins are formed separately to the base to produce a heat sink heat radiation of various sizes and shapes The sieve can be easily manufactured.
본 발명에 의한 조립식 방열체(1)는 크게, 베이스(10)와 다수 개의 방열핀(20)으로 구성된다. 도 1에는 본 발명에 의한 방열체(1)의 사시도가 도시되어 있다.The prefabricated heat sink 1 according to the present invention is largely composed of a base 10 and a plurality of heat radiation fins 20. 1 is a perspective view of a heat sink 1 according to the present invention.
상기 베이스(10)는 다수 개의 방열핀(20)이 서로 간격을 가지며 일정한 위치에 배치될 수 있도록 방열핀(20)을 고정해주는 부분으로, 수평한 긴 판형으로 이루어진다. 그리고 상면에는 서로 간격을 두고 위치한 두 개의 레일(11a)로 구성된 길이방향의 가이드(11)가 형성되어, 다수 개의 방열핀(20)을 베이스(10) 상에 나란하게 고정하는 역할을 하게 된다.The base 10 is a part for fixing the heat dissipation fins 20 so that the plurality of heat dissipation fins 20 are spaced from each other and disposed at a predetermined position, and has a horizontal long plate shape. And the upper surface is formed with a guide 11 in the longitudinal direction consisting of two rails (11a) spaced apart from each other, and serves to secure a plurality of heat radiation fins 20 side by side on the base (10).
방열핀(20)은 판형으로 이루어져 엘이디에서 발생한 열을 방출하는 역할을 하는 것으로, 그 하단부 테두리에 가이드홈(21)이 구비된다. 각각의 방열핀(20)은 그 가이드홈(21)에 베이스(10)의 가이드(11)가 삽입되도록 베이스(10)의 상면에 세워져 조립된다. 각각의 방열핀(20)은 서로 간격을 두고 배치되어 엘이디에서 발생하는 열을 효과적으로 배출할 수 있다.The heat dissipation fin 20 has a plate shape and serves to release heat generated from the LED, and the guide groove 21 is provided at the lower edge thereof. Each heat dissipation fin 20 is assembled to stand on the upper surface of the base 10 so that the guide 11 of the base 10 is inserted into the guide groove 21. Each of the heat dissipation fins 20 may be spaced apart from each other to effectively discharge the heat generated from the LED.
이러한 본 발명에 의한 조립식 방열체(1)는, 원하는 엘이디조명의 규격에 맞게 베이스(10)의 길이를 형성하고 베이스(10)의 가이드(11)에 다수 개의 방열핀(20)을 끼우는 것만으로 제작이 가능하므로 매우 쉽게 다양한 규격으로 형성하는 것이 가능하고, 형성 가능한 방열체의 규격에 거의 제한이 없다.The prefabricated heat sink 1 according to the present invention is formed by forming a length of the base 10 in accordance with the desired LED lighting standard and simply inserting a plurality of heat radiation fins 20 into the guide 11 of the base 10.

상기 방열핀(20)과 베이스(10)는, 방열핀(20)의 크기가 작은 경우에는 베이스(10)의 가이드(11)에 방열핀(20)이 억지끼움될 수 있도록 가이드홈(21)을 형성하거나 방열핀(20)을 베이스(10)의 가이드(11)에 끼운 후 단순히 접착제로 접합할 수도 있으나, 방열핀(20)의 크기가 큰 경우에는 아래와 같은 방법에 의하여 접합될 수 있다.The heat dissipation fins 20 and the base 10 may form guide grooves 21 so that the heat dissipation fins 20 may be inserted into the guides 11 of the base 10 when the sizes of the heat dissipation fins 20 are small. After the heat dissipation fin 20 is inserted into the guide 11 of the base 10, it may be simply bonded with an adhesive, but when the size of the heat dissipation fin 20 is large, it may be bonded by the following method.
즉, 상기 방열핀(20)의 가이드홈(21)은 역사다리꼴 형태로 형성하고, 가이드(11)의 레일(11a)들은 적어도 상기 방열핀(20)과 결합하는 위치에서 가이드홈(21)의 역사다리꼴 형태에 맞게 벌어지도록 형성한다. 이처럼 가이드(11)의 레일(11a)들이 벌어지면 방열핀(20)의 가이드홈(21)에 가이드(11)가 단순히 삽입되는 것이 아니라 걸리게 되어 가이드(11)에서 방열핀(20)이 이탈하는 것이 방지된다.That is, the guide groove 21 of the heat dissipation fin 20 is formed in the inverted trapezoidal shape, the rail (11a) of the guide 11 at least in the trapezoid of the guide groove 21 in the position that is coupled with the heat radiation fin (20). It is formed so as to fit in shape. As such, when the rails 11a of the guide 11 are opened, the guide 11 is not simply inserted into the guide groove 21 of the heat dissipation fin 20 but is caught, thereby preventing the heat dissipation fin 20 from being separated from the guide 11. do.
상기 가이드(11)의 레일(11a)들이 가이드홈(21)의 역사다리꼴 형태에 맞게 벌어지도록 형성되는 경우, 상기 가이드(11)의 레일(11a)들은 방열핀(20)들 사이의 위치에서 상단부가 가이드홈(21)의 역사다리꼴 윗변 길이보다 넓게 벌어져 형성될 수 있다.When the rails 11a of the guide 11 are formed to open in conformity with the inverted trapezoidal shape of the guide groove 21, the rails 11a of the guide 11 may have upper ends at positions between the heat dissipation fins 20. It may be formed wider than the length of the inverted trapezoid upper side of the guide groove (21).
이 경우, 방열핀(20)의 측면은 방열핀(20)들 사이에 위치한 가이드 레일(11a)들의 벌어진 부분에 걸리게 되므로 방열핀(20)이 가이드(11)의 레일(11a) 방향으로도 이동하는 것을 방지할 수 있다.In this case, the side surface of the heat dissipation fins 20 is caught by the gaps of the guide rails 11a positioned between the heat dissipation fins 20, thereby preventing the heat dissipation fins 20 from moving in the direction of the rails 11a of the guide 11. can do.
이러한 가이드(11)의 레일(11a)과 방열핀(20)의 결합은 아래와 같은 방법에 의하여 이루어질 수 있다. 도 2에는 가이드(11)의 레일(11a)과 방열핀(20)을 결합시키는 방법에 관한 설명도가 도시되어 있다.The coupling of the rail 11a and the heat dissipation fin 20 of the guide 11 may be performed by the following method. 2 is an explanatory diagram illustrating a method of coupling the rail 11a and the heat dissipation fin 20 of the guide 11 to each other.
먼저, 가이드(11)의 레일(11a)들이 베이스(10)의 상면에 수직하게 세워진 상태의 베이스(10)와 가이드홈(21)이 역사다리꼴 형태인 방열핀(20)을 준비하고(도 2의 (a)), 베이스(10)의 가이드(11)가 방열핀(20)의 가이드홈(21)에 삽입되도록 베이스(10)의 상면 위에 다수 개의 방열핀(20)을 세운다(도 2의 (b)). 그리고 방열핀(20)들 사이 위치의 가이드 레일(11a)들 사이에 공구 등을 삽입한 후 가압하여 가이드(11)의 레일(11a)들 사이의 상단부 간격을 가이드홈(21)의 역사다리꼴 윗변 길이 이상으로 벌린다(도 2의 (c)). 이렇게 하면 방열핀(20)들 사이 위치에서는 가이드 레일(11a)들의 상단부 간격이 가이드홈(21)의 역사다리꼴 윗변 길이 이상이 되어 방열핀(20)이 가이드(11)의 길이방향으로 이동하는 것을 방지할 수 있지만, 가이드홈(21) 위치에서의 가이드 레일(11a)들은 방열핀(20)의 가이드홈(21)에 의해 변형이 제한되어 가이드홈(21)의 역사다리꼴 형상에 맞는 정도로만 벌어지게 된다.First, the base 11 and the guide groove 21 in a state in which the rails 11a of the guide 11 are erected perpendicularly to the upper surface of the base 10 are prepared with a heat radiation fin 20 having an inverted trapezoidal shape (see FIG. 2). (a)), the plurality of heat dissipation fins 20 are erected on the top surface of the base 10 so that the guide 11 of the base 10 is inserted into the guide groove 21 of the heat dissipation fin 20 (FIG. 2B). ). In addition, a tool is inserted between the guide rails 11a at positions between the heat dissipation fins 20, and then pressurized so that the gap between the upper ends of the rails 11a of the guide 11 is increased. It opens with the above (FIG. 2 (c)). This prevents the heat dissipation fins 20 from moving in the longitudinal direction of the guide 11 in a position between the heat dissipation fins 20 such that the distance between the upper end portions of the guide rails 11a is greater than the length of the inverted trapezoidal upper side of the guide groove 21. However, the guide rails 11a at the guide grooves 21 position are limited to deformation by the guide grooves 21 of the heat dissipation fins 20 so as to only open to the extent corresponding to the inverted trapezoidal shape of the guide grooves 21.
상기 방열핀(20)의 일측면 하단에는, 방열핀(20)의 면방향과 수직한 하부간격유지대(22)가 형성될 수 있다. 도 3에는 이러한 방열핀(20)이 자세하게 도시되어 있다.A lower interval supporter 22 perpendicular to the surface direction of the heat dissipation fin 20 may be formed at a lower end of one side of the heat dissipation fin 20. 3 shows such a heat dissipation fin 20 in detail.
상기 하부간격유지대(22)는 방열핀(20)들 사이의 간격에 맞게 방열핀(20)의 일측면에서 수직하게 돌출되도록 형성하여, 별도의 장치나 노력없이도 방열핀(20)들 사이의 간격을 일정하게 맞출 수 있도록 하고, 방열핀(20)을 베이스(10)에 접합하는 작업 등을 하는 중에도 일정하게 맞춘 방열핀(20)들 사이의 간격이 달라지는 것을 방지하게 된다.The lower spacing holder 22 is formed to protrude vertically from one side of the heat dissipation fin 20 in accordance with the spacing between the heat dissipation fins 20, so that the interval between the heat dissipation fins 20 without any device or effort is fixed. The gap between the heat dissipation fins 20 uniformly adjusted during the operation of bonding the heat dissipation fins 20 to the base 10 is prevented from being changed.
그뿐만 아니라, 방열핀(20)을 베이스(10) 위에 세웠을 때 하부간격유지대(22)의 면이 베이스(10)의 상면과 면접하게 되므로 얇은 판형으로 형성되는 방열핀(20)이 넘어지지 않고 베이스(10) 위에서 세워진 상태를 유지할 수 있다.In addition, when the heat sink fin 20 is placed on the base 10, the surface of the lower interval holder 22 is in contact with the upper surface of the base 10, so that the heat sink fin 20 formed in a thin plate shape does not fall over the base. (10) It can maintain its upright position.
상기 방열핀(20)은 끼움형(20A)과 일반형(20B)으로 이루어질 수 있다.The heat dissipation fin 20 may be made of a fitting type 20A and a general type 20B.

Each of the first and second upper interval supporters 23 and 24 includes a horizontal part H and a vertical part V, each of which is formed in a 'B' shape, respectively. The horizontal portion (H) of the different lengths are formed so that the gap (S) between the vertical portion (V) of each of the first and second upper spaced interval support (23, 24) when viewed from the side of the fitted heat radiating fin (20A) Will be formed. And the general mold 20B does not have the same structure as the 1st and 2nd upper space | interval holding parts 23 and 24 of the fitting mold 20A, as shown to FIG. 3 (b).

The upper ends of the general type heat dissipation fins 20B are fitted into the gaps formed between V to form the heat dissipation fin assembly A.
이러한 방열핀 조립체(A)는, 단면이 사각형이 되어 베이스(10) 위에 보다 안정적으로 세워질 수 있을 뿐만 아니라, 방열핀(20) 두 개씩이 결합되므로 방열핀(20)을 고정하기 위하여 가이드 레일(11a)들의 간격을 벌릴 때에 모든 방열핀(20)들 사이에서 레일(11a)들을 벌리지 않고 방열핀 조립체 사이에서만 레일(11a)들을 벌리더라도 모든 방열핀(20)들을 베이스(10)에 견고하게 고정할 수 있도록 해준다.The heat dissipation fin assembly (A), the cross section is a square can not only stand more stably on the base 10, but also because the two heat dissipation fins 20 are coupled to each other of the guide rails (11a) to fix the heat dissipation fins (20) When the gap is opened, even though the rails 11a are opened only between the heat dissipation fin assemblies without opening the rails 11a between all the heat dissipation fins 20, all the heat dissipation fins 20 can be firmly fixed to the base 10.
