Description

일체형 라디에이터 및 이의 조립 방법Integral radiator and its assembly method

본 발명은 일체형 라디에이터에 관한 것으로, 엔진용 라디에이터와 전장용 라디에이터가 일체로 구성된 라디에이터에 있어서, 서로 다른 작동 온도에 의한 열 변형과 이에 따른 부품 손상을 최소화할 수 있는 일체형 라디에이터에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an integrated radiator, and more particularly, to a radiator in which an engine radiator and an electric radiator are integrated, and an integrated radiator capable of minimizing thermal deformation and component damage due to different operating temperatures.

일반적으로 차량의 엔진룸 전방에 구비되는 프론트 엔드 모듈을 도 1에 도시하였다.In general, the front end module provided in front of the engine room of the vehicle is shown in FIG.

도 1에 도시한 프론트 엔드 모듈(1)은 캐리어(2)와 상기 캐리어(2)의 후방에 장착되는 응축기(3)와 전장용 라디에이터(6)와 엔진용 라디에이터(4) 및 팬 슈라우드 조립체(5)를 포함하는 쿨링모듈과, 상기 캐리어(2)의 전방에 장착되며 상기 캐리어(2)의 후방으로 공기가 유통되도록 상측 및 하측에 각각 개구부(8, 9)가 형성된 범퍼 빔(7)을 포함하여 형성된다.The front end module 1 shown in FIG. 1 comprises a carrier 2, a condenser 3 mounted on the rear of the carrier 2, a radiator 6 for the electric field, a radiator 4 for the engine 4 and a fan shroud assembly ( Cooling module including a 5) and the bumper beam (7) which is mounted to the front of the carrier (2) and the openings (8, 9) formed in the upper and lower sides, respectively, so that air flows to the rear of the carrier (2) It is formed to include.

이 때, 상기 응축기는 냉방 사이클 과정 중에 압축기에서 송출되는 고압의 기상 냉매를 외기와 열교환하여 고온 고압의 액체로 응축하고, 팽창수단으로 송출한다.At this time, the condenser condenses the high-pressure gaseous refrigerant discharged from the compressor during the cooling cycle to the outside air by condensing it into a liquid of high temperature and high pressure and sending it to the expansion means.

또, 상기 라디에이터(Radiator)는 열교환기의 범주에 포함되는 구성요소로서, 상기 라디에이터는 엔진의 온도가 일정 온도 이상으로 상승되는 것을 방지하기 위한 구성이다.In addition, the radiator (Radiator) is a component included in the category of the heat exchanger, the radiator is configured to prevent the temperature of the engine rises above a certain temperature.

일반적으로 내연기관은 항상 고온ㆍ고압의 가스를 연소시키는 과정에서 매우 많은 양의 열이 발생되며, 상기 열이 적절히 냉각되지 않으면 과열로 인하여 실린더와 피스톤을 포함하는 각종 부품이 손상되므로, 상기 실린더 주위에 냉각수를 수용하는 재킷을 구비하고, 상기 재킷 내부의 냉각수를 순환시킴으로써 상기 냉각수가 엔진으로부터 발생하는 열을 흡수함으로써 엔진이 냉각되도록 하고 있다.In general, internal combustion engines always generate a very large amount of heat in the process of combusting high-temperature and high-pressure gas, and if the heat is not properly cooled, various parts including the cylinder and the piston are damaged due to overheating. The jacket is provided in the cooling chamber, and the engine is cooled by absorbing heat generated from the engine by circulating the cooling water inside the jacket.

즉, 라디에이터는 엔진 내부를 순환하면서 연소에 의해 발생된 열을 흡수한 고온의 냉각수가 워터펌프에 의해 순환되면서, 외부에 열을 방출하도록 하여 엔진의 과열을 방지하며 최적의 운전 상태가 유지되도록 하는 열교환기이다.That is, the radiator circulates through the engine while absorbing the heat generated by the combustion, and the hot water is circulated by the water pump, thereby dissipating heat to the outside to prevent overheating of the engine and to maintain an optimal operating state. Heat exchanger.

한편, 하이브리드 차량에서는 엔진 외에도 모터, 인버터, 배터리 스택 등을 포함하는 전기, 전자 구성품인 전장부품 역시 냉각해야하는데, 상기 엔진을 통과한 냉각수와 전장부품을 통과한 냉각수는 일정 온도 차이가 발생되어 하나의 냉각 시스템을 갖지 못한다.On the other hand, in a hybrid vehicle, in addition to the engine, electric and electronic components including electric motors, inverters, and battery stacks must also be cooled. The coolant passing through the engine and the coolant passing through the electric component have a constant temperature difference. Does not have a cooling system.

따라서 차량용 냉각 시스템은 크게 엔진 냉각용 시스템과, 전장부품 냉각용 시스템이 개별적으로 구비되며, 엔진 냉각을 위한 라디에이터와 전장부품 냉각을 위한 라디에이터가 개별적으로 구비된다.Therefore, the vehicle cooling system is largely provided with an engine cooling system and an electronic component cooling system separately, and a radiator for engine cooling and a radiator for electronic component cooling are separately provided.

상기 전장부품 냉각용 라디에이터는 일반적으로 별도로 제작되어 응축기의 상측 또는 하측에 조립된다.The radiator for electric component cooling is generally manufactured separately and assembled on the upper or lower side of the condenser.

위 방안은 전장부품 냉각용 라디에이터와 응축기의 조립을 위한 부품이 필요하며, 조립 공정 추가에 따른 생산성이 저하되는 문제점이 있다.The above solution requires a component for assembling the radiator and the condenser for cooling the electric component, there is a problem that the productivity is reduced by the addition of the assembly process.
