PROBLEM TO BE SOLVED: To improve the fuel efficiency of the engine of a hybrid vehicle, reduce harmful components in exhaust gas and simplify a piping system, to make the overall size of the hybrid car small, reduce the fluctuation width of the temperature cycle applied to electrical components and improve the operating live times and reliabilities of the components through quick engine warm up. SOLUTION: Components such as an engine 1, a dynamoelectric machine 2, etc., are mounted as a driving system on a hybrid car, which has a plurality of cooling pipes and radiators 5e and 5m. In a hybrid car, a heat exchanger 4 which conducts heat exchanging between a circulating system which cools the engine 1 and a circulation system cooling the components, such as the dynamoelectric machine 2, etc., which do not include the engine 1 is provided. |
