Description

팬 어셈블리{Fan Assembly}Fan Assembly

본 발명은 팬 어셈블리에 관한 것으로, 특히 프로젝터 또는 프로젝션 텔레비젼의 램프에서 발생하는 열을 냉각시키기 위한 팬 어셈블리에 관한 것이다. The present invention relates to a fan assembly, and more particularly, to a fan assembly for cooling heat generated in a lamp of a projector or a projection television.

주지하는 바와 같이, 대화면 디스플레이 장치의 보급에 따라 다양한 프로젝션 텔레비젼과 프로젝터가 개발되어 사용되고 있다. As is well known, various projection televisions and projectors have been developed and used in accordance with the spread of large-screen display devices.

이러한 프로젝션 텔레비젼과 프로젝터와 같은 프로젝션 시스템은 광원을 발생시켜 주사하는 방식으로 고출력의 램프가 적용되는데, 이 램프는 사용 과정에서 많은 열을 발생시키고, 이러한 열은 광학계의 광학적 특성을 저하시키게 된다. Projection systems such as projection televisions and projectors are applied to a high-power lamp by generating and scanning a light source, which generates a lot of heat during use, and this heat degrades the optical characteristics of the optical system.

따라서, 이러한 고출력의 램프에서 발생되는 열을 적절히 냉각시켜줄 필요가 있는 바, 통상적으로 램프의 일측에 냉각팬을 설치하여 램프에 공기를 강제 송풍시키는 방식으로 램프의 열을 강제 냉각시키고 있다. Therefore, it is necessary to properly cool the heat generated in such a high-power lamp, typically, by installing a cooling fan on one side of the lamp forcibly cooling the heat of the lamp by forcibly blowing air to the lamp.

첨부된 도면의 도 1은 프로젝션 시스템의 조명계에 종래의 팬 어셈블리가 결합되는 구조를 보여주는 것으로, 팬 어셈블리(1)는 램프(미도시)가 내설되는 램프 하우징(4)의 일측면에 면착된 상태에서 스크류(3)에 의해 램프 하우징(4)에 고정된다. FIG. 1 of the accompanying drawings shows a structure in which a conventional fan assembly is coupled to an illumination system of a projection system, and the fan assembly 1 is attached to one side of a lamp housing 4 in which a lamp (not shown) is installed. Is fixed to the lamp housing 4 by means of a screw 3.

그런데, 상기와 같은 팬 어셈블리(1)는 팬(2)이 고속으로 회전하기 때문에 팬(2)의 진동이 발생하게 되고, 이러한 진동은 스크류(3)를 통하여 램프 하우징(4)으로 전달되면서 소음을 발생시키고, 정밀도가 요구되는 광학계의 특성을 저하시키게 된다. However, in the fan assembly 1 as described above, since the fan 2 rotates at a high speed, vibration of the fan 2 is generated, and the vibration is transmitted to the lamp housing 4 through the screw 3 while making noise. And deteriorates the characteristics of the optical system requiring precision.

이러한 문제를 개선하기 위한 것으로, 대한민국 공개특허공보 2003-71073호(2003. 09. 03 공개)에 냉각팬과 시스템 하우징의 스크류 체결부위에 대략 원통형의 방진부재를 개재시킴으로써 상기 방진부재가 팬의 진동을 흡수하고, 이로써 팬의 진동이 시스템 하우징으로 전달되는 것을 최소화한 저진동 냉각팬이 개시되어 있다. In order to improve such a problem, the vibration is the vibration of the fan by interposing a substantially cylindrical anti-vibration member in the screw fastening portion of the cooling fan and the system housing in the Republic of Korea Patent Publication No. 2003-71073 (published on Sep. 03, 2003) A low vibration cooling fan is disclosed which minimizes the transmission of vibrations and thereby minimizes the vibration of the fan to the system housing.

그러나, 상기와 같은 저진동 냉각팬은 스크류 체결부위마다 여러개의 방진부재를 개재시킨 상태에서 스크류를 체결해야 하므로 냉각팬을 프로젝션 시스템에 결합시키는 작업이 매우 어렵고, 종방향 진동 흡수력은 우수하나 횡방향의 진동 흡수력은 상대적으로 낮아, 전체적으로 방진 효과를 향상시키는데 문제가 있다. However, the low vibration cooling fan as described above requires fastening the screws in a state where a plurality of dustproof members are interposed in each screw fastening portion, so that the cooling fan is difficult to join the projection system, and the longitudinal vibration absorption is excellent, but the lateral direction is excellent. Vibration absorbing power is relatively low, there is a problem in improving the overall dust-proof effect.

이에 본 발명은 상기와 같은 문제를 해결하기 위하여 안출된 것으로, 팬 어셈블리가 적용되는 시스템의 구조물과의 결합이 용이하게 이루어짐과 더불어 우수한 방진 성능을 갖는 팬 어셈블리를 제공함에 그 목적이 있다. Accordingly, the present invention has been made to solve the above problems, and an object of the present invention is to provide a fan assembly having excellent dustproof performance as well as easy coupling with a structure of a system to which a fan assembly is applied.

그 다음, 사용자는 방진용 체결부재(150)의 경사부(154)의 전단부를 팬하우징(120)의 체결공(122)에 맞추어 밀어넣으면 상기 경사부(154)의 절개홈(155) 양측부분이 수축되면서 체결공(122)을 통과하여 결합되고, 경사부(154)가 체결공(122)을 완전히 빠져나오게 되면 경사부(154) 후방의 걸림턱부(154a)가 체결공(122)의 후면에 걸려 지지되면서 이탈이 방지된다. Then, the user pushes the front end of the inclined portion 154 of the anti-vibration fastening member 150 in accordance with the fastening hole 122 of the fan housing 120, both sides of the cut groove 155 of the inclined portion 154. When the contraction is coupled through the fastening hole 122, and the inclined portion 154 completely exits the fastening hole 122, the locking step 154a behind the inclined portion 154 is the rear of the fastening hole 122 It is supported by the jammer and prevents its escape.

상기와 같이 방진용 체결부재(150)가 팬하우징(120)의 체결공(122)에 결합됨으로써 마운트 브라켓(110)과 팬하우징(120) 간의 결합이 이루어진다. 이 상태에서 마운트 브라켓(110)은 양측부의 고정편(114)이 램프 하우징(4)(도 1참조)의 양측면에 면착된 후 스크류 체결공(122)을 통해 스크류(미도시)가 체결됨으로써 램프 하우징(4)에 고정된다. As described above, the anti-vibration fastening member 150 is coupled to the fastening hole 122 of the fan housing 120 to thereby engage the mount bracket 110 and the fan housing 120. In this state, the mounting bracket 110 is attached to both sides of the lamp housing 4 (see FIG. 1) by the fixing pieces 114 of both sides, and then the lamp (not shown) is fastened through the screw fastening hole 122. It is fixed to the housing 4.

이와 같이 팬 어셈블리(100)가 램프 하우징(4)(도 1참조)과 같은 구조물에 장착된 후, 발열체의 냉각을 위해 냉각팬(130)이 고속으로 회전하게 되면 냉각팬(130) 회전에 의해 팬하우징(120)이 진동하게 된다. After the fan assembly 100 is mounted on the same structure as the lamp housing 4 (see FIG. 1), when the cooling fan 130 rotates at a high speed for cooling the heating element, the cooling fan 130 rotates. The fan housing 120 is vibrated.

이 때, 상기 마운트 브라켓(110)과 팬하우징(120)은 진동 흡수력이 우수한 방진용 체결부재(150)에 의해 서로 연결되어 있으므로 팬하우징(120)의 진동이 마운트 브라켓(110)으로 전달되는 정도가 현저히 감소되고, 따라서 램프 하우징(4)과 같이 팬 어셈블리(100)가 고정되는 구조물의 진동이 감소되고, 소음이 감소된다. At this time, since the mount bracket 110 and the fan housing 120 are connected to each other by the vibration fastening member 150 having excellent vibration absorption power, the vibration of the fan housing 120 is transmitted to the mount bracket 110. Is significantly reduced, so that vibration of the structure to which the fan assembly 100 is fixed, such as the lamp housing 4, is reduced, and noise is reduced.

이러한 진동 및 소음의 감소는 특히 프로젝션 시스템의 광학계와 같이 고도의 정밀도가 요구되는 시스템에서 큰 이점을 제공하지만, 이외에도 냉각용 팬 어셈블리가 적용되는 기타 다른 시스템에서도 큰 이점을 제공한다. These reductions in vibration and noise provide significant advantages, particularly in systems requiring high precision, such as optical systems in projection systems, but in addition to other systems in which cooling fan assemblies are applied.

이상에서와 같이 본 발명에 따르면, 팬의 회전시 팬하우징에서 발생하는 진동이 마운트 브라켓으로 전달되는 양이 현저히 줄어들게 되고, 따라서 팬 어셈블리가 장착되는 구조물의 진동을 감소시킴과 더불어 소음을 감소시킬 수 있다. As described above, according to the present invention, the amount of vibration generated in the fan housing during the rotation of the fan to the mounting bracket is significantly reduced, thus reducing the vibration of the structure on which the fan assembly is mounted and noise can be reduced. have.
