본 고안은 열교환기와 팬 쉬라우드의 결합구조에 관한 것이다.The present invention relates to a coupling structure of a heat exchanger and a fan shroud.

통상적으로 자동차 엔진의 냉각방식은 공랭식과 수냉식으로 구분할 수 있는데, 수냉식 엔진 냉각장치는 엔진의 외주면을 따라 유동하는 냉각수로써 엔진을 냉각시키는 방식이다. 보통 자동차 엔진의 전면에는 라디에이터가 설치되며, 엔진 냉 각수는 라디에이터를 통해 유동함으로써 외부의 공기와 열교환이 이루어진다. 라디에이터의 열교환 작용을 강제하기 위하여 라디에이터의 일측에는 팬 조립체가 설치된다. 팬 조립체는 일반적으로 팬과, 상기 팬을 회전구동시키는 구동 모터와, 팬을 지지하는 팬 쉬라우드(fan shroud)를 구비한다.In general, a cooling method of an automotive engine may be classified into an air cooling type and a water cooling type. A water cooling engine cooling device is a method of cooling an engine by cooling water flowing along an outer circumferential surface of the engine. Usually, a radiator is installed on the front of an automobile engine, and engine coolant flows through the radiator to exchange heat with outside air. In order to force the heat exchange action of the radiator, a fan assembly is installed at one side of the radiator. The fan assembly generally includes a fan, a drive motor for rotating the fan, and a fan shroud for supporting the fan.

일반적인 자동차에 이용되는 냉각 시스템에 있어서, 적어도 두 개의 쿨링 팬(엔진의 냉각수를 냉각시키기 위한 라디에이터 냉각용 팬과, 공기조화장치의 응축기를 냉각시키기 위한 팬)이 이용된다. 이러한 팬은 장착위치 및 열교환기로의 기류 이동방향에 따라 푸셔 타입(pusher type)과 풀러 타입(puller type)으로 대별된다.In a cooling system used in a typical automobile, at least two cooling fans (a radiator cooling fan for cooling the engine's cooling water and a fan for cooling the condenser of the air conditioner) are used. These fans are roughly classified into a pusher type and a puller type according to the mounting position and the direction of air flow to the heat exchanger.

통상적으로 상기 팬들을 열교환기에 장착함에 있어서, 응축기에는 푸셔 타입의 팬을 적용하고 라디에이터에는 풀러 타입의 팬을 적용하거나 응축기와 라디에이터 모두에 풀러 타입 또는 푸셔 타입의 팬을 채용하고 있다. 또한 라디에이터와 응축기 사이에 팬을 설치한 미들 타입(middle type)의 경우에는 라디에이터에 푸셔 팬을 채용하고 응축기에는 풀러 팬을 채용하고 있다. 팬은 팬 쉬라우드에 장착되어 열교환기에 부착되는데 이 경우 팬 쉬라우드와 열교환기를 결합시키기 위한 수단이 필요하다.Typically, in mounting the fans to the heat exchanger, a pusher type fan is applied to the condenser and a puller type fan is applied to the radiator, or a fuller type or pusher type fan is used for both the condenser and the radiator. In the case of a middle type in which a fan is installed between the radiator and the condenser, a pusher fan is used for the radiator and a puller fan is used for the condenser. The fan is mounted on the fan shroud and attached to the heat exchanger, in which case means are needed to join the fan shroud and the heat exchanger.

도1은 일반적인 열교환기(라디에이터)에 팬 쉬라우드가 결합된 구조를 나타내는 사시도이다. 도시한 바와 같이, 열교환기(10)와 팬 쉬라우드(20)는 볼트 및 너트에 의해 결합되는데, 상기 팬 쉬라우드(20)에서 돌출되게 형성된 결합 플랜지(22, 24)의 단부에서 볼트 너트 체결수단(30)에 의해 결합된다.1 is a perspective view showing a structure in which a fan shroud is coupled to a general heat exchanger (radiator). As shown, the heat exchanger 10 and the fan shroud 20 are joined by bolts and nuts, which bolt nuts are fastened at the ends of the coupling flanges 22, 24 protruding from the fan shroud 20. Coupled by means 30.

그런데, 이와 같이 구성된 종래 열교환기와 팬 쉬라우드의 결합구조는, 볼트 및 너트를 사용하여 팬 쉬라우드를 조립하므로 팬 쉬라우드를 조립하기가 용이하지 않으며 조립비용 및 생산성이 떨어진다는 문제점이 있었다.However, the coupling structure of the conventional heat exchanger and the fan shroud configured as described above has a problem in that the fan shroud is not easily assembled using bolts and nuts, and thus the assembly cost and productivity are low.

따라서, 본 고안은 상기 문제점을 해결하기 위해 이루어진 것으로서, 본 고안의 목적은 볼트 너트를 사용하지 않고 팬 쉬라우드를 열교환기에 간단히 결합할 수 있는 열교환기와 팬 쉬라우드의 결합구조를 제공하는 데 있다.Accordingly, the present invention has been made to solve the above problems, and an object of the present invention is to provide a coupling structure of a heat exchanger and a fan shroud that can simply couple the fan shroud to the heat exchanger without using a bolt nut.

본 고안에 의한 열교환기와 팬 쉬라우드의 결합구조는, 탱크를 구비한 열교환기와, 팬과 이 팬의 주위를 감싸도록 설치되는 팬 쉬라우드를 결합하는 구조에 있어서, 상기 열교환기의 탱크에는 그 내부에 돌기가 형성된 ㄷ 단면형의 탄성클립이 부착되고, 상기 팬 쉬라우드의 외측에는 상기 탄성클립에 끼워져 상기 돌기에 의해 이탈이 방지되도록 그 단부에 상기 걸림홈이 형성되어 상기 돌기가 걸리는 플랜지가 돌출하여 형성되어 있는 것을 특징으로 한다.The coupling structure of the heat exchanger and the fan shroud according to the present invention has a structure in which a heat exchanger having a tank and a fan shroud installed to surround the fan and the fan shroud are arranged inside the tank of the heat exchanger. An elastic clip of a cross-sectional shape having protrusions formed thereon is attached to the outer side of the fan shroud, and the engaging groove is formed at an end thereof so as to be prevented from being separated by the protrusions. It is characterized by being formed.

이하 본 고안의 실시예에 대해 첨부도면을 참조하여 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

본 고안은 탱크를 구비한 열교환기와, 팬과 이 팬의 주위를 감싸도록 설치되는 팬 쉬라우드를 결합하는 구조에 관한 것으로서, 응축기, 라디에이터 등 다양한 열교환기에 팬 쉬라우드가 결합되는 구조에 적용될 수 있다. 본 실시예에서는 라디에이터를 예로 들어 설명한다. 적용되는 전체적인 구조는 도1에 도시한 바와 같다.The present invention relates to a structure for coupling a heat exchanger having a tank and a fan shroud installed to surround the fan and the fan, and may be applied to a structure in which the fan shroud is coupled to various heat exchangers such as a condenser and a radiator. . In this embodiment, a radiator will be described as an example. The overall structure applied is as shown in FIG.

도2은 열교환기와 팬쉬라우드의 결합부의 평면도이고, 도3은 도2에서 화살표 A-A 선에 따른 단면도이다. 도시한 바와 같이, 열교환기(100)의 탱크(110)에는 ㄷ 단면형의 탄성 클립(120)이 고정되어 있다. 상기 탄성 클립(120)은 그 하측 플랜지(123)가 상기 탱크(110)에 용접등에 의해 탱크(110)의 길이방향 하측이 트여 있다. Figure 2 is a plan view of the coupling portion of the heat exchanger and the fan shroud, Figure 3 is a cross-sectional view taken along the arrow A-A line in FIG. As shown, the c cross-sectional elastic clip 120 is fixed to the tank 110 of the heat exchanger 100. In the elastic clip 120, the lower flange 123 is opened in the longitudinal direction of the tank 110 by welding or the like to the tank 110.

상기 탄성 클립(120)의 상측플랜지(122) 및 하측 플랜지(123)의 내면에는 돌기(122a)(123a)가 각각 형성되어 있다.Protrusions 122a and 123a are formed on inner surfaces of the upper flange 122 and the lower flange 123 of the elastic clip 120, respectively.

상기 팬 쉬라우드(200)의 좌우 외측(도1참조)에는 조립하기 위한 플랜지(210)가 형성되어 있다. 상기 플랜지(210)의 외단에는 보강 플랜지(211)가 형성되어 있는데, 상기 플랜지(210)의 단부(212)에는 상기 탄성 클립(120)에 삽입되도록 보강 플랜지가 제거되어 있다.Flange 210 for assembling is formed on the left and right outer sides (see FIG. 1) of the fan shroud 200. A reinforcing flange 211 is formed at an outer end of the flange 210, and the reinforcing flange is removed at the end 212 of the flange 210 so as to be inserted into the elastic clip 120.

상기 플랜지(210)의 단부(212)에는 상기 돌기(122a)(123a)가 걸리도록 걸림홈(212a)이 형성되어 있다.A locking groove 212a is formed at the end 212 of the flange 210 so as to catch the protrusions 122a and 123a.

이와 같이 구성된 열교환기와 팬 쉬라우드의 결합구조에서, 상기 팬 쉬라우드(200)는 열교환기(100)의 탱크(110)의 길이방향 하측에서 상기 탄성 클립(120)에 삽입하여 결합하게 되는데, 상기 플랜지(210)의 단부(212)에 형성된 걸림홈(212a)에 상기 돌기(122a)(123a)가 걸리어 팬 쉬라우드(200)가 간단히 결합된다. In the coupling structure of the heat exchanger and the fan shroud configured as described above, the fan shroud 200 is inserted into the elastic clip 120 at the lower side in the longitudinal direction of the tank 110 of the heat exchanger 100 and coupled thereto. The projections 122a and 123a are caught in the engaging grooves 212a formed at the end 212 of the flange 210 so that the fan shroud 200 is simply coupled.

본 고안에 의한 열교환기와 팬 쉬라우드의 결합구조에 의하면, 볼트 너트를 사용하지 않고 팬 쉬라우드를 열교환기에 간단히 결합할 수 있으므로, 팬 쉬라우드를 조립하기가 용이하며 조립비용이 줄어들고 생산성이 향상되는 효과가 있다.According to the coupling structure of the heat exchanger and the fan shroud according to the present invention, since the fan shroud can be simply coupled to the heat exchanger without using a bolt nut, it is easy to assemble the fan shroud, and the assembly cost is reduced and productivity is improved. It works.
