Description

자동차용 배터리 냉각 블록 조립구조{ASSEMBLING STRUCTURE OF BATTERY BLOCK ASSY-COOLING FOR VEHICLE}Vehicle battery cooling block assembly structure {ASSEMBLING STRUCTURE OF BATTERY BLOCK ASSY-COOLING FOR VEHICLE}

본 발명은 자동차용 배터리 냉각 블록 조립구조에 관한 것으로서, 보다 상세하게는 원소재의 사용을 줄이면서 베이스 플레이트와 커버 플레이트를 정확하게 결합할 수 있는 자동차용 배터리 냉각 블록 조립구조에 관한 것이다.The present invention relates to a vehicle battery cooling block assembly structure, and more particularly, to a vehicle battery cooling block assembly structure capable of accurately coupling a base plate and a cover plate while reducing the use of raw materials.

일반적으로 하이브리드 자동차나 전기 자동차에는 배터리 팩(battery pack)이 탑재되며, 이 배터리 팩은 배터리 셀(battery cells)을 일정한 개수로 묶어 연결한 배터리 모듈(battery module)을 다수개 연결하여 구성하게 된다.In general, a battery pack is mounted on a hybrid vehicle or an electric vehicle, and the battery pack is configured by connecting a plurality of battery modules that are connected by tying a certain number of battery cells.

배터리 팩을 자동차에 탑재하기 위하여 배터리 팩은 배터리 냉각 블록에 장착하게 된다.In order to mount the battery pack on a vehicle, the battery pack is mounted on the battery cooling block.

배터리 셀은 예를 들면 리튬이온 2차전지(lithium-ion secondary battery) 등으로 이루어질 수 있으며, 이러한 배터리 셀을 복수 개를 연결하여 하나의 배터리 모듈을 형성하고, 자동차에 요구되는 배터리 용량에 따라서 다수개의 배터리 모듈을 직렬이나 병렬 또는 직병렬 형태로 연결하여 배터리 냉각 블록에 장착한다.The battery cell may be made of, for example, a lithium-ion secondary battery, and a plurality of such battery cells are connected to form one battery module, and a plurality of battery cells are formed according to the battery capacity required for the vehicle. The battery modules are connected in series, parallel, or series-parallel and mounted on the battery cooling block.

이러한 배터리 팩은 충 방전 시 열이 발생하므로 배터리 팩을 냉각시키기 위하여 배터리 냉각 블록은 냉각수가 순환할 수 있도록 냉각수 유로가 형성될 수 있다.Since heat is generated during charging and discharging of the battery pack, a cooling water flow path may be formed in the battery cooling block to circulate the cooling water in order to cool the battery pack.

이렇게 배터리 냉각 블록에 냉각수가 순환하면서 배터리 셀 간의 온도 편차 및 배터리 셀의 방전 온도를 낮추어 배터리 팩의 수명과 출력유지 시간을 증대 시킬 수 있다.As the coolant circulates in the battery cooling block, the temperature deviation between battery cells and the discharge temperature of the battery cells are lowered, thereby increasing the lifespan and output maintenance time of the battery pack.

통상적으로 배터리 냉각 블록은 2개의 금속 플레이트로 이루어진 베이스 플레이트와 커버 플레이트로 이루어져 이들을 서로 접합하여 제작하게 되는데, 이때 베이스 플레이트와 커버 플레이트의 가장자리에 다수의 고정부로 임시로 고정한 후, 둘레면을 따라서 브레이징(brazing) 공법으로 접합하게 된다.Typically, the battery cooling block consists of a base plate made of two metal plates and a cover plate, and is manufactured by bonding them together.At this time, after temporarily fixing the base plate and the cover plate with a plurality of fixing parts, along the circumferential surface. It is joined by a brazing method.

이렇게 베이스 플레이트와 커버 플레이트를 임시로 고정하기 위하여 베이스 플레이트의 둘레면에는 간격을 유지하며 외부로 연장되는 날개부가 형성되고, 이 날개부를 180도 정도 밴딩하여 커버 플레이트에 임시로 고정하게 된다.In this way, in order to temporarily fix the base plate and the cover plate, a wing portion extending outward while maintaining a gap is formed on the circumferential surface of the base plate, and the wing portion is bent about 180 degrees to be temporarily fixed to the cover plate.

그리고 이 상태에서 베이스 플레이트와 커버 플레이트의 센터와 외측면을 따라서 브레이징 공법으로 접합하여 배터리 냉각 블록을 제작하게 된다.In this state, the battery cooling block is fabricated by brazing along the center and outer surfaces of the base plate and the cover plate.

그러나 이와 같이 날개부를 밴딩할 때 베이스 플레이트와 커버 플레이트가 약간씩 틀어질 가능성이 매우 높으며, 그로 인한 공차로 인하여 베이스 플레이트와 커버 플레이트가 정확하게 접합되지 못하므로 브레이징 불량 및 배터리 팩과 장착을 하기 위한 조립 홀이 틀어져 조립이 되지 않는 불량이 발생 할 수 있다However, there is a very high possibility that the base plate and the cover plate will be slightly twisted when the wing is bent in this way, and due to the tolerance, the base plate and the cover plate cannot be accurately bonded. A defect that cannot be assembled due to a twisted hole may occur.

이렇게 브레이징 작업이 양호하게 이루어지지 않으면 베이스 플레이트와 커버 플레이트 둘레면 사이에 미세한 틈이 생기거나 조립이 되자 않아 제조된 제품을 사용할 수 없다.If the brazing operation is not performed well, a minute gap between the base plate and the circumferential surface of the cover plate or assembly is not possible, and the manufactured product cannot be used.

본 발명이 제안하는 자동차용 배터리 냉각 블록 조립구조는 베이스 플레이트와 커버 플레이트로 이루어지고 이들 베이스 플레이트와 커버 플레이트를 포개 고정부로 임시 고정한 상태로 둘레면을 따라서 브레이징으로 접합한 자동차용 배터리 냉각 블록 조립구조에 있어서, 상기 고정부는 베이스 플레이트와 커버 플레이트에 각각 형성된 홈과 돌기로 이루어진 자동차용 배터리 냉각 블록 조립구조를 제공한다.The vehicle battery cooling block assembly structure proposed by the present invention is composed of a base plate and a cover plate, and the base plate and the cover plate are temporarily fixed with a superimposed fixing part, and the vehicle battery cooling block is assembled by brazing along the circumferential surface. In the structure, the fixing portion provides a battery cooling block assembly structure for a vehicle comprising grooves and protrusions respectively formed in the base plate and the cover plate.

상기 베이스 플레이트와 커버 플레아트에 형성된 홈과 돌기는 베이스 플레이트와 커버 플레이트를 서로 겹친 상태에서 펀치 또는 프레스로 가압하여 형성된다.The grooves and protrusions formed in the base plate and the cover plate are formed by pressing the base plate and the cover plate with a punch or press while overlapping each other.

상기 베이스 플레이트와 커버 플레이트 사이에는 냉각수가 순활 될 수 있는 냉각수 유로가 형성되고, 이 냉각수 유로에 냉각수가 공급 및 배출될 수 있도록 커버 플레이트의 양측으로는 냉각수 공급포트와 냉각수 배출포트가 각각 형성된다.A cooling water flow path through which cooling water can be purified is formed between the base plate and the cover plate, and cooling water supply ports and cooling water discharge ports are respectively formed on both sides of the cover plate so that cooling water can be supplied and discharged to the cooling water flow path.

상기 배터리 냉각 블록은 차량에 장착할 수 있도록 둘레면을 따라서 간격을 유지하며 다수의 장착홈이 형성되고, 이 장착홈 주변에는 고정부재 등을 체결할 수 있는 조립홀이 형성된다.The battery cooling block maintains a gap along a circumferential surface so that it can be mounted on a vehicle, and a plurality of mounting grooves are formed, and an assembly hole for fastening a fixing member or the like is formed around the mounting groove.

본 발명에 의한 자동차용 배터리 냉각 블록 조립구조는 베이스 플레이트와 커버 플레이트를 돌기와 홈으로 이루어진 고정부로 고정하므로 종래의 날개부가 필요 없어 원소재의 사용량을 그만큼 줄일 수 있다.In the vehicle battery cooling block assembly structure according to the present invention, since the base plate and the cover plate are fixed with a fixing part composed of a protrusion and a groove, a conventional wing part is not required, thereby reducing the amount of raw materials used.

또한 고정부가 베이스 플레이트와 커버 플레이트의 임시 고정을 정확하고 견고하게 고정하여 베이스 플레이트와 커버 플레이트의 틀어짐이 발생되지 않아 브레이징 작업을 용이하고 정확하게 할 수 있어 제품의 불량 발생을 방지할 수 있다.In addition, the fixing unit accurately and firmly fixes the temporary fixing of the base plate and the cover plate so that the base plate and the cover plate are not twisted, so that the brazing operation can be performed easily and accurately, thereby preventing product defects.

Show.

하이브리드 자동차 또는 전기 자동차에는 배터리 팩(battery pack)이 탑재되며, 이 배터리 팩은 배터리 냉각 블록(2)에 장착하여 탑재할 수 있다.A battery pack is mounted on a hybrid vehicle or an electric vehicle, and the battery pack can be mounted on the battery cooling block 2 to be mounted.

상기 배터리 냉각 블록(2)은 배터리 팩을 지지할 수 있는 충분한 강도를 갖는 금속으로 이루어진 플레이트 형태로 제작된다.The battery cooling block 2 is manufactured in the form of a plate made of metal having sufficient strength to support the battery pack.

실질적으로 본 발명에 제공된 배터리 냉각 블록(2)은 금속재질로 이루어진 베이스 플레이트(4)와 커버 플레이트(6)로 이루어진다.The battery cooling block 2 substantially provided in the present invention comprises a base plate 4 and a cover plate 6 made of a metal material.

베이스 플레이트(4)와 커버 플레이트(6)는 별도로 각각 제조되고, 이들을 겹친 상태로 고정부(8)로 임시로 고정한 상태에서 외측 테두리면을 브레이징 공법으로 접합하여 배터리 냉각 블록(2)를 제작하게 된다.The base plate 4 and the cover plate 6 are separately manufactured, and the outer rims are bonded together by a brazing method in a state where they are temporarily fixed with a fixing part 8 in a superimposed state to fabricate the battery cooling block 2. do.

이때 베이스 플레이트(4)와 커버 플레이트(6) 사이에는 냉각수 유로(미도시)가 형성되고, 이 냉각수 유로에 냉각수가 공급 및 배출될 수 있도록 커버 플레이트(6)의 양측으로는 냉각수 공급포트(10)와 냉각수 배출포트(12)가 각각 형성된다.At this time, a cooling water flow path (not shown) is formed between the base plate 4 and the cover plate 6, and cooling water supply ports 10 are provided on both sides of the cover plate 6 so that cooling water can be supplied and discharged to the cooling water flow path. ) And cooling water discharge ports 12 are respectively formed.

이렇게 배터리 냉각 블록(2) 내부에 냉각수가 유동될 수 있도록 구성하는 이유는 배터리 팩을 구성하는 배터리 모듈의 충전 및 방전 과정에서 열이 발생되는데, 이러한 충, 방전 과정에서 발생한 배터리 모듈의 열이 효과적으로 제거되지 못하면 열 축적이 일어나 결과적으로 배터리 모듈의 열화가 촉진되고, 경우에 따라서는 발화 또는 폭발이 일어날 수 있으므로 고출력 대용량의 배터리 팩에 장착되는 배터리 냉각 블록(2)는 배터리 모듈들을 냉각시키는 것이 매우 중요하다.The reason why the cooling water is configured to flow inside the battery cooling block 2 is that heat is generated during the charging and discharging process of the battery modules constituting the battery pack, and the heat of the battery module generated during the charging and discharging process is effectively If it is not removed, heat accumulation occurs and consequently the deterioration of the battery module is accelerated, and in some cases, ignition or explosion may occur. It is important.

이렇게 배터리 냉각 블록(2) 내부에는 냉각수 유로가 형성되므로 냉각수가 외부로 유출되지 않도록 배터리 냉각 블록(2)의 둘레면을 기밀하게 접합해야 하는데, 이를 위하여 고정부(8)가 베이스 플레이트(4)와 커버 플레이트(6)를 견고하게 고정하는 것이 중요하다.In this way, the cooling water flow path is formed inside the battery cooling block 2, so that the circumferential surface of the battery cooling block 2 must be airtightly bonded so that the cooling water does not leak to the outside. To this end, the fixing part 8 is the base plate 4 It is important to securely fix the and cover plate (6).

본 발명의 자동차용 배터리 냉각 블록 조립구조에 제공된 고정부(8)는 베이스 플레이트(4)에 형성된 홈(14)과 커버 플레이트(6)에 형성되어 상기 홈(14)에 결합되는 돌기(16)로 이루어진다.The fixing part 8 provided in the vehicle battery cooling block assembly structure of the present invention has a groove 14 formed in the base plate 4 and a protrusion 16 formed in the cover plate 6 and coupled to the groove 14 Consists of

상기 홈(14)과 돌기(16)는 펀치 또는 프레스 등을 이용하여 각각 형성하고 이들을 조립할 수도 있고, 또는 베이스 플레이트(4)와 커버 플레이트(6)를 겹친 다음 프레스 등으로 가압하여 한 번에 일괄적으로 형성할 수 있다.The groove 14 and the protrusion 16 may be formed respectively using a punch or a press, and they may be assembled, or the base plate 4 and the cover plate 6 are overlapped and then pressed with a press, etc. It can be formed as an enemy.

이러한 고정부(8)는 배터리 냉각 블록(2)의 가장자리를 따라서 몇 개의 위치에 형성할 수 있다.This fixing part 8 can be formed in several positions along the edge of the battery cooling block 2.

이렇게 고정부(8)가 홈(14)과 돌기(16)로 이루어지면 종래에 비하여 베이스 플레이트(4)와 커버 플레이트(6)의 고정을 더욱 견고하게 할 수 있다. 이에 따라 베이스 플레이트(4)와 커버 플레이트(6)를 고정할 때, 베이스 플레이트(4)와 커버 플레이트(6)가 정확하게 일치하지 못하고 틀어지는 불량을 방지할 수 있고, 또 고정 작업을 간단하고 빠르게 할 수 있다.When the fixing part 8 is made of the groove 14 and the protrusion 16 in this way, the base plate 4 and the cover plate 6 can be more securely fixed compared to the conventional one. Accordingly, when fixing the base plate 4 and the cover plate 6, defects in which the base plate 4 and the cover plate 6 are not accurately matched and twisted can be prevented, and the fixing operation can be made simple and fast. I can.

또한 종래의 날개부가 필요 없으므로 원재료를 그만큼 적게 사용할 수 있고, 또 베이스 플레이트(4)와 커버 플레이트(6)의 고장작업을 종래의 날개부를 밴딩하는 것에 비하여 공정이 단순하고 빠르게 진행되므로 배터리 냉각 블록(2) 제작비용을 줄일 수 있고 제작시간을 단축할 수 있어 생산성을 향상시킬 수 있다.In addition, since the conventional wing part is not required, it is possible to use less raw materials, and the process is simpler and faster than that of bending the conventional wing part for failure work of the base plate 4 and the cover plate 6, so the battery cooling block ( 2) Production cost can be reduced and production time can be shortened, which can improve productivity.
