FUEL EFFICIENCY IMPROVEMENT SYSTEM BY RECOVERING WASTE HEAT OF CONSTRUCTION MACHINERY
According to the present invention, a fuel efficiency improvement system by recovering waste heat of a construction machine, which includes a hydraulic system, a cooling system and an engine, comprises an organic Rankine cycle and a radiator. The organic Rankine cycle comprises: a first heat exchanger transferring heat between a hydraulic fluid of the hydraulic system and an operational fluid; and a second heat exchanger transferring heat between the operational fluid coming out of the first heat exchanger and cooling water of the cooling system, and circulates the operational fluid to exchange heat with waste heat or waste energy of the hydraulic system, the cooling system and the engine in the order precisely given. The radiator is positioned at one side of the engine and is provided with the cooling water of the cooling system. The cooling water of the cooling system, which is out from the engine, can be selectively distributed to the radiator or the second heat exchanger. According to the present invention, the fuel efficiency improvement system by recovering waste heat of a construction machine is able to recover heat energy of hydraulic oil, cooling water and waste gas, which is discarded from the construction machine with a hydraulic system, and convert the recovered heat energy into a driving source. Thus, fuel efficiency of the construction machine can be improved.
본 발명에 따른 건설기계의 페열 회수를 통한 연비 향상 시스템은, 유압계통, 냉각계통, 엔진을 구비하는 건설기계에 있어서, 상기 유압계통의 작동유와 상기 작동유체를 열 교환시키는 제1 열교환기 및 상기 제1 열교환기에서 나온 상기 작동유체와 상기 냉각계통의 냉각수와 열 교환시키는 제2 열교환기를 포함하고, 상기 유압계통, 상기 냉각계통 및 상기 엔진의 폐열 또는 폐에너지와 차례대로 열교환하도록 작동유체를 순환시키는 유기랭킨 사이클; 및 상기 엔진의 일측에 구비되어 상기 냉각계통의 냉각수를 공급받는 라디에이터; 를 포함하며, 상기 엔진에서 나온 상기 냉각계통의 냉각수는 상기 라디에이터 또는 상기 제2 열교환기로 선택적으로 분배될 수 있다. 본 발명에 따른 건설기계의 페열 회수를 통한 연비 향상 시스템은 유압 시스템을 구비한 건설기계에서 버려지는 작동유, 냉각수 및 폐기가스의 열 에너지를 회수하여 건설기계를 구동시킬 수 있는 구동원으로 변환시킬 수 있다. 이에 따라, 건설기계의 연비를 절감할 수 있다.
