Description

하이브리드 차량용 쿨링시스템{Cooling system for hybrid electric vehicles}Cooling system for hybrid electric vehicles

본 발명은 하이브라이드 차량용 쿨링시스템에 관한 것으로, 특히 서로 다른 작동유체를 함께 이용가능하게 루프를 구성하도록 한 하이브리드 차량용 쿨링시스템에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hybrid vehicle cooling system, and more particularly, to a hybrid vehicle cooling system configured to form a loop in which different working fluids can be used together.

최근에 배출가스를 줄이면서 연비향상을 위한 차세대 친환경 차량의 개발에 많은 연구가 활발하게 진행 중에 있다. 화석연료를 줄이거나 대체하기 위한 차량으로 하이브리드 차량(Hybrid Electric Vehicle)과 수소연료전지 차량(Fuel cell electric vehicle)으로 구분할 수 있다.Recently, a lot of research is being actively conducted on the development of next-generation eco-friendly vehicles for improving fuel efficiency while reducing emission gas. As a vehicle for reducing or replacing fossil fuels, it can be classified into a hybrid electric vehicle and a fuel cell electric vehicle.

현재 사용되는 하이브리드 차량은 저속운전시 배터리로 구동하고, 고속운전시 엔진으로 구동하도록 되어 있다. 즉 저속운전시 전기모터가 동력원이 될 때 별도의 발전기 및 배터리를 이용하여 구동하게 되며, 고속운전시 엔진으로 구동하면서 배터리에는 충전이 이루어지도록 되어 있다. 이러한 하이브리드 차량은 배터리의 무게를 줄이면서 장시간 구동하도록 배터리의 용량을 키워야만 그 활용성을 높여서 실용화에 접근할 수 있다. 이를 위해서는 배터리를 충분히 냉각할 수 있는 쿨 링시스템의 개발이 필요하다.Currently used hybrid vehicles are driven by a battery at low speed and an engine at high speed. In other words, when the electric motor becomes a power source during low speed operation, it is driven using a separate generator and battery, and the battery is charged while driving with an engine during high speed operation. Such a hybrid vehicle can increase the utility of the battery by increasing the capacity of the battery so as to drive the battery for a long time while reducing the weight of the battery. This requires the development of a cooling system that can cool the battery sufficiently.

한편, 수소연료전지 차량은 연료전지를 에너지원으로 사용하여 연료의 산화에 의해서 생기는 화학에너지를 전기에너지로 변환시키도록 되어 있다. 즉 수소연료전지 차량은 전기를 생산하는 연료전지 스택과, 상기 연료전지 스택에 연료와 공기를 가습하여 공급하는 가습기, 상기 가습기에 수소를 공급하는 연료공급부와, 상기 가습기에 산소를 포함하는 공기를 공급하는 공기공급부와, 상기 연료전지 스택을 냉각하기 위한 냉각모듈을 포함하고 있다. 이러한 수요연료전지 차량 역시 연료전지 스택을 충분히 냉각할 수 있는 쿨링시스템의 개발이 필요하다.Meanwhile, a hydrogen fuel cell vehicle is configured to convert chemical energy generated by oxidation of fuel into electrical energy using a fuel cell as an energy source. That is, the hydrogen fuel cell vehicle includes a fuel cell stack for generating electricity, a humidifier for humidifying and supplying fuel and air to the fuel cell stack, a fuel supply unit for supplying hydrogen to the humidifier, and air containing oxygen in the humidifier. An air supply unit for supplying, and a cooling module for cooling the fuel cell stack. Such demand fuel cell vehicles also need to develop a cooling system that can sufficiently cool the fuel cell stack.

하이브리드 차량은 일반 차량과 마찬가지로, 엔진의 동력을 전달받아 구동되는 압축기에 의하여 고온, 고압으로 압축된 냉매가 응축기로 유입되어 액체 상태로 응축된 다음, 팽창밸브를 통과하면서 팽창된 후 증발기를 통하여 차실로 공급되는 공기와 열교환 다음 압축기로 복귀되는 냉방시스템(에어콘시스템)을 구비하고 있다.Like a general vehicle, a hybrid vehicle, like a general vehicle, is introduced into a condenser by a compressor driven by an engine and driven at high temperature and high pressure, condensed into a liquid state, and then expanded while passing through an expansion valve. It is equipped with a cooling system (air conditioning system) which returns to the compressor after heat exchange with the air supplied to the furnace.

이러한 냉방시스템은 엔진룸에 1개의 증발기를 배치하여 싱글타입으로 구성할 수 있고, 엔진룸에 증발기를 배치하고 차량 후방에 별도의 증발기를 배치하여 듀얼타입으로 구성할 수 있다.Such a cooling system can be configured as a single type by placing one evaporator in the engine room, and can be configured as a dual type by placing an evaporator in the engine room and a separate evaporator behind the vehicle.

한편, 하이브리드 차량은 배터리를 성능을 높이도록 배터리를 쿨링하는 배터리 쿨링시스템을 구비하고 있다.On the other hand, the hybrid vehicle is provided with a battery cooling system for cooling the battery to increase the performance of the battery.

그런데, 종래기술에 따른 하이브리드 차량의 쿨링시스템은 차실을 냉방하는 냉방시스템(에어콘 시스템)과 배터리를 쿨링하는 배터리 쿨링시스템이 별개로 되어 전체 쿨링시스템이 복잡할 뿐만 아니라, 프론트 냉방모드, 리어 냉방모드, 프론트/리어 냉방모드, 배터리 쿨링모드를 각각 제어해야 하는 불편함이 있었다.However, the cooling system of the hybrid vehicle according to the prior art has a cooling system (air conditioner system) for cooling the cabin and a battery cooling system for cooling the battery separately, so that the entire cooling system is not only complicated, but also the front cooling mode and the rear cooling mode. There was an inconvenience of having to control the front / rear cooling mode and the battery cooling mode respectively.

또한, 향후 개발될 예정인 하이브리드 차량에서 요구되는 수준으로 충분한 쿨링성능을 확보하기 어려웠다.In addition, it was difficult to secure sufficient cooling performance to the level required for hybrid vehicles to be developed in the future.
