필드코일 어셈블리 구조{Assembling structure of Field Coil}Assembling structure of field coil

본 발명은 필드코일 어셈블리 구조에 관한 것으로서, 더욱 상세하게는 코어하우징의 일측에 방열판을 설치하여 코일의 온도를 낮춤으로서 전자클러치의 성능을 향상시킨 필드코일 어셈블리 구조에 관한 것이다.The present invention relates to a field coil assembly structure, and more particularly, to a field coil assembly structure in which a heat sink is installed on one side of a core housing to lower the temperature of a coil to improve the performance of an electronic clutch.

일반적으로 전자클러치의 필드코일 어셈블리는 전원 공급시 권선된 코일의 전자기 유도에 의해 자기장을 형성하여, 그에 따른 자기력으로 풀리의 마찰면측으로 압축기 구동축의 허브 디스크가 흡인되어 동력적으로 연결됨으로써, 엔진에 의해 회전하는 풀리의 구동력을 압축기 구동축의 허브 디스크에 전달하게 하는 전기장치이다.In general, the field coil assembly of the electromagnetic clutch forms a magnetic field by electromagnetic induction of the coil wound upon power supply, and the hub disk of the compressor drive shaft is attracted to the friction surface side of the pulley by the magnetic force and is connected to the engine. It is an electric device that transmits the driving force of the rotating pulley to the hub disk of the compressor drive shaft.

아울러, 상기 코일에 대한 전원의 인가 여부에 따라 압축기에 대한 동력을 단속하여 공조장치의 냉방시스템의 작동을 제어하는 역할을 한다.In addition, it controls the operation of the cooling system of the air conditioning apparatus by intermittent power to the compressor in accordance with whether or not the power to the coil is applied.

이러한, 상기 전자클러치의 필드코일 어셈블리는 도 1 및 도 2 에 도시된 바와 같이, 전자코일이 링형으로 권선되어 형성된 전자코일체(11)와; 상기 전자코일체(11)를 수용하고, 전자코일체(11)로부터 인출된 한 쌍의 인출선(11a)이 위치하는 슬리브 접속부(12)를 갖는 보빈(13)과; 상기 전자코일체(11)를 내장한 보빈(13)을 수용한 상태로 풀리(3)에 삽입되어 압축기(1)의 프런트헤드에 고정되는 코어하우징(14)과; 상기 전자코일체(11)와 보빈(13)이 코어하우징(14)으로부터 이탈되지 않게 코어하우징(14)의 개방면을 밀폐하는 커버(15);로 구성된다.The field coil assembly of the electromagnetic clutch may include an electromagnetic coil body 11 formed by winding an electromagnetic coil in a ring shape, as shown in FIGS. 1 and 2; A bobbin (13) for receiving the electromagnetic coil body (11) and having a sleeve connecting portion (12) in which a pair of lead wires (11a) drawn out from the electromagnetic coil body (11) are located; A core housing 14 inserted into the pulley 3 in a state in which the bobbin 13 containing the electromagnetic coil body 11 is accommodated and fixed to the front head of the compressor 1; And a cover 15 which seals the open surface of the core housing 14 so that the electromagnetic coil body 11 and the bobbin 13 do not separate from the core housing 14.

그리고, 상기 슬리브 접속부(12)는 외부전원이 연결된 커넥터(미도시)와 접속됨으로써 상기 전자코일체(11)에 자기장이 형성되는 것이다.In addition, the sleeve connecting portion 12 is connected to a connector (not shown) connected to an external power source to form a magnetic field in the electromagnetic coil body 11.

이러한, 상기 필드코일 어셈블리(10)는 압축기(1)의 프런트헤드에 압입되는 방식으로 결합된다.The field coil assembly 10 is coupled in such a way that it is pressed into the front head of the compressor 1.

그러나, 종래의 필드코일 어셈블리(10)는 에어컨의 작동시 압축기(1)측에서의 열기와 전자클러치 작동 중에 발생하는 열기에 의해 코일(11)측의 온도가 상승하게 되는데, 이렇게 코일(11)측의 온도가 상승하게 되면 저항이 증가하고 이로 인해 전류값이 감소하여 전자클러치의 성능을 나타내는 암페어 턴(ampere turn)수도 감소하게 되면서 흡입력 측면에서도 불리하여 전차클러치의 성능을 저하시키는 문제가 있었다.However, in the field coil assembly 10 of the related art, the temperature of the coil 11 side is increased by the heat generated during the operation of the air conditioner and the electromagnetic clutch during the operation of the air conditioner. As the temperature increases, the resistance increases, and the current value decreases, thereby decreasing the number of ampere turns indicating the performance of the electronic clutch, which is disadvantageous in terms of suction force, thereby degrading the performance of the tank clutch.

도시된 바와 같이, 본 발명에 따른 필드코일 어셈블리(100)는 전자코일이 링형으로 권선되어 형성된 전자코일체(101)와, 상기 전자코일체(101)를 수용하며 일측에 전자코일체(101)로 부터 인출된 한 쌍의 인출선(102)이 위치하는 슬리브 접속부(108)를 구비하는 코어하우징(110)으로 구성된다.As shown, the field coil assembly 100 according to the present invention is an electromagnetic coil 101 formed by winding an electromagnetic coil in a ring shape, and the electronic coil body 101 accommodates the electronic coil body 101 on one side. It consists of a core housing 110 having a sleeve connecting portion 108 is a pair of lead wires (102) drawn from the.

여기서, 상기 전자코일체(101)는 보빈(105)에 삽입된 상태로 상기 코어하우징(110)에 수용되며, 상기 전자코일체(101) 및 보빈(105)이 코어하우징(110)으로 부터 이탈되지 않도록 코어하우징(110)의 개방면은 커버(115)로 밀폐된다.Here, the electronic coil body 101 is accommodated in the core housing 110 in a state inserted into the bobbin 105, the electronic coil body 101 and the bobbin 105 is separated from the core housing 110. The opening surface of the core housing 110 is sealed by the cover 115 so as not to.

또한, 상기 코어하우징(110)은 압축기(1)의 프런트헤드에 결합하기 위한 플랜지(111)를 더 포함한다.In addition, the core housing 110 further includes a flange 111 for coupling to the front head of the compressor 1.

한편, 상기 슬리브 접속부(108)는 외부전원을 공급하는 커넥터(5)와 결합되게 된다.On the other hand, the sleeve connecting portion 108 is coupled to the connector 5 for supplying external power.

그리고, 상기 코어하우징(110)의 일측에는 코일(101)측에서 발생하는 열을 외부로 발산시켜 코일(101)의 온도를 낮출수 있도록 방열판(120)의 설치된다.In addition, one side of the core housing 110 is provided with a heat sink 120 so as to lower the temperature of the coil 101 by dissipating heat generated from the coil 101 side to the outside.

상기 방열판(120)은 코어하우징(110)의 플랜지(111) 일측면에 면접촉하는 원형 플레이트(121)와, 상기 원형 플레이트(121)의 일측에 방사상으로 일체로 돌출 형성되는 다수의 핀(122)으로 이루어진다.The heat sink 120 has a circular plate 121 which is in surface contact with one side of the flange 111 of the core housing 110, and a plurality of fins 122 which are integrally projected radially on one side of the circular plate 121. )

여기서, 상기 방열판(120)은 열전달이 우수한 금속재질로 형성하는 것이 바람직하다. Here, the heat sink 120 is preferably formed of a metal material excellent in heat transfer.

따라서, 에어컨의 작동시 압축기(1)측에서 발생하는 열기와 전자클러치 작동 중에 발생하는 열기에 의해 내부 코일(101)의 온도가 상승하게 되는데, 이때 상승한 열은 상기 코어하우징(110)을 통해 방열판(120)으로 전열되고, 방열판(120)으로 전열된 열은 외부공기와 열교환하면서 외부로 발산하게 된다.Therefore, the temperature of the internal coil 101 is increased by the heat generated from the compressor 1 side and the heat generated during the operation of the electronic clutch when the air conditioner is operated. In this case, the heat is increased through the core housing 110. Heat is transferred to (120), heat is transferred to the heat sink 120 is dissipated to the outside while heat exchange with the outside air.

이렇게, 상기 코일(101)측에서 발생하는 열이 상기 방열판(120)을 통해 외부로 발산됨으로서 코일(101)의 온도가 낮아짐과 동시에 코일(101)의 암페어 턴수가 증가되어 전자클러치의 성능이 향상되는 것이다.As such, the heat generated from the coil 101 is dissipated to the outside through the heat sink 120, thereby lowering the temperature of the coil 101 and increasing the number of amp turns of the coil 101, thereby improving the performance of the electronic clutch. Will be.

이상에서 살펴본 바와 같이, 본 발명에서는 상기 방열판(120)이 하드쉘 타입의 필드코일 어셈블리(100)에 적용된 것에 대해서만 설명하였지만, 여기에 한정되지 않고 에폭시 타입의 필드코일 어셈블리에도 동일하게 적용 가능하며 동일한 효과를 얻을 수 있다.As described above, in the present invention, the heat sink 120 has been described only for being applied to the hard shell type field coil assembly 100.
