본 발명은 전기자동차용 Ni-MH 배터리(이하 배터리라함)의 냉각핀에 관한 것으로, 더 상세하게는 배터리에서 발산되는 열을 방열시키기 위해 배터리에 장착되는 냉각핀을 공기와의 접촉면적이 증가되도록 형성하여 냉각핀의 냉각효과를 증대시킬 수 있도록 한 것이다.The present invention relates to a cooling fin of a Ni-MH battery (hereinafter referred to as a battery) for an electric vehicle, and more particularly, to a cooling fin of an Ni-MH battery So that the cooling effect of the cooling fin can be increased.
일반적으로, 전기자동차는 전기에너지를 모터(motor)의 시동, 조명 및 기타 전장품의 전원으로 사용함은 물론, 주행의 동력원으로 사용하며, 상기 동력원인 전기를 발전하기 위하여 전기자동차에는 전기자동차용 배터리가 탑재된다.Generally, an electric vehicle uses electric energy as a power source for driving, as well as for starting a motor, lighting, and other electrical products, and for generating electric power as a power source of the electric vehicle, Lt; / RTI >
한편, 배터리의 충전 및 방전시에는 배터리에 열이 발생되며, 배터리의 손상 및 성능저하를 방지하기 위하여 배터리는 항상 적정 온도를 유지하여야 됨에 따라 배터리의 충전 및 방전시 발생되는 열을 방열하기 위하여 배터리에는 냉각핀이 설치되어 배터리에서 발생되는 열을 냉각시키므로써 배터리가 적정온도를 유지되도록 한다.In order to dissipate the heat generated during the charging and discharging of the battery, the battery must be maintained at a proper temperature in order to prevent damage and deterioration of the battery. A cooling pin is installed to cool the heat generated by the battery so that the temperature of the battery is maintained at an appropriate level.
상기와 같이 배터리에서 발생되는 열을 방열시키기 위하여 배터리에 설치되는 종래의 냉각핀(1)은 제1도에서와 같이 일정간격으로 다수개의 돌기(2)가 돌출되며, 상기 돌기(2)는 중앙부의 돌기(2a)를 중심으로 좌우에 돌출된 돌기(2b)들의 길이가 다르게 구성되어 산형으로 형성되며, 상기 냉각핀(1)은 제2도에서 도시되는 바와같이 배터리(3)의 양측면에 설치되어 배터리(3)에서 발산되는 열이 냉각핀(1)에 형성된 돌기(2)사이를 흐르면서 열이 발산된다.As shown in FIG. 1, a plurality of protrusions 2 are protruded at a predetermined interval in a conventional cooling fin 1 installed in a battery to dissipate heat generated in the battery, The left side of the projection 2a The cooling fins 1 are provided on both sides of the battery 3 as shown in FIG. 2, and the heat generated by the battery 3 is dissipated from the heat dissipating protrusions 2b. Heat is dissipated as it flows between the protrusions (2) formed on the cooling fin (1).
그러나, 상기와 같이 종래의 냉각핀(1)은 다수개의 돌기(2)가 공기의 흐름과 직각을 이루도록 형성되어 공기의 흐름을 억제하여, 공기가 냉각핀(1)의 돌기(2)사이를 통과하지 못하고, 냉각핀(1)의 주위로 분산되므로 공기와 냉각핀(1)과의 접촉면적이 적게되어 냉각핀(1)에서의 냉각효과가 미흡하였고, 그로인하여 배터리(3) 주위에 열을 구비한 공기가 흐르게 되므로 배터리(3)의 효율이 저하됨은 물론 배터리(3)가 손상될 우려가 소지되어 있었다.However, as described above, the conventional cooling fin 1 is formed such that the plurality of projections 2 are formed at a right angle to the flow of air, so that the flow of air is suppressed, and the air flows between the projections 2 of the cooling fin 1 The contact area between the air and the cooling fin 1 is reduced and the cooling effect of the cooling fin 1 is insufficient. As a result, the heat generated around the battery 3 The efficiency of the battery 3 is lowered and the battery 3 may be damaged.
본 발명은 이러한 제반 문제점을 해소하기 위해 발명된 것으로, 냉각핀의 내부에 홀을 형성하여 알루미늄 압출가공의 작업성을 향상시키며, 냉각핀의 중량 감소 및 공기와의 접촉면적을 증가시켜 냉각효과를 증대시키려는 데 그 목적이 있다.The present invention has been made in order to solve these problems, and it is an object of the present invention to improve the workability of aluminum extrusion processing by forming a hole in the inside of the cooling fin, to reduce the weight of the cooling fin and to increase the contact area with air, The purpose is to increase.
상기와 같은 목적을 달성하기 위한 본 발명은, 냉각핀의 일측면에 전후방이 연통되는 원형의 홀이 구비된 돌기가 돌출된 구조로,배터리에서 발생되는 열을 가지고 있는 공기가 상기 냉각핀의 홀을 통과하므로써 공기와 냉각핀간의 접촉면적이 증가된다.In order to achieve the above object, according to the present invention, A protrusion provided with a circular hole communicating with the rear is protruded so that air having heat generated from the battery passes through the hole of the cooling fin, thereby increasing the contact area between the air and the cooling pin.
이하 첨부된 도면에 의거하여 본 발명의 구성을 설명하면 다음과 같다.DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the configuration of the present invention will be described with reference to the accompanying drawings.
제3도 내지 제4도에서 도시되는 바와같이 본 발명 냉각핀(10)은 일측면은 평면이며, 타측면으로는 내부에 전ㆍ후방이 연통되는 원형의 홀(11)이 구비된 다수개의 원형의 돌기(12)가 일정간격을 두고 길이방향으로 돌출된다.As shown in FIG. 3 through FIG. 4, the cooling fin 10 of the present invention has a flat surface on one side and a plurality of round holes 11 having a circular hole 11, The protrusions 12 protrude in the longitudinal direction at regular intervals.
상기 냉각핀(10)은 공기가 원형의 홀(11)을 관통하도록 배터리(20)의 양측면에 설치된다.The cooling fins 10 are installed on both sides of the battery 20 such that the air passes through the circular holes 11. [
이와같이 구성된 본 발명은 배터리(20)의 충전 및 방전시 배터리(20)에서 발생되는 열을 가지고 있는 공기가 냉각팬에 의해 배터리(20)의 외부로 유출되며, 상기 공기가 냉각핀(10)의 홀(11)을 통과하고, 또한, 돌기(12)와 돌기(12) 사이를 흐르게 된다.In the present invention thus configured, the air having heat generated in the battery 20 is discharged to the outside of the battery 20 by the cooling fan when the battery 20 is charged and discharged, Passes through the hole 11 and also flows between the protrusion 12 and the protrusion 12.
따라서, 이러한 본 발명은 공기와 냉각핀(10)의 접촉면적이 증가되며, 홀(11)이 구비된 돌기(12)가 일정크기 및 일정간격으로 형성되어 알루미늄 압출가공의 작업이 용이해진다.Therefore, in the present invention, the contact area of the air and the cooling fin 10 is increased, and the protrusions 12 provided with the holes 11 are formed at a predetermined size and at regular intervals, thereby facilitating the aluminum extrusion processing.
이상에서 살펴본 바와같이 본 발명은 공기와 냉각핀과의 접촉면적이 증가되어 냉각핀에서의 방열량이 크게되어 냉각효과가 증대되며, 냉각핀의 중량 감소 및 압출가공 작업의 편의성을 향상시킬 수 있는 매우 유용한 발명이다.As described above, according to the present invention, the contact area between the air and the cooling fins is increased to increase the amount of heat dissipated from the cooling fins, thereby increasing the cooling effect, and reducing the weight of the cooling fins and improving the convenience of the extrusion processing. It is a useful invention.
