Since heat exchanger 10 connects heat transmission branch 41 and exhaust piping 20 simultaneously, when fluid flows through heat transmission branch 41,
It can carry out heat with exhaust piping 20 to exchange, so that the heat of exhaust piping 20 just passes to the fluid of heat transmission branch 41.
Since heat transmission branch 41 is connected to heat exchanger 10 with general branch 36, when the fluid in battery heating circuit flows through hot friendship
When parallel operation 10, heat can be carried out with the fluid of heat transmission branch 41 and exchanged, exhaust piping 20 and heat transmission branch 41
Heat just passes to battery heating branch 600.
Certainly, in other embodiments, can also be arranged between heat transmission branch 41 and engine cooling circuit 40
One valve port of four triple valves 400, the 4th triple valve 400 connects heat transmission branch 41, the other two of the 4th triple valve 400
Valve port connects engine cooling circuit 40.Second triple valve 200 and the 4th triple valve 400 are respectively arranged at heat transmission branch 41
Both ends.Similarly, third triple valve 300, third triple valve can also be set between battery heating branch 600 and general branch 36
300 valve port connection battery heats branch 600, and two valve ports of residue of third triple valve 300 connect battery cooling circuit
30, the first triple valve 100 and third triple valve 300 are respectively arranged at the both ends that battery heats branch 600.
Heat transmission branch 41 can with the partial branch of engine cooling circuit 40 form heat transmission circuit, and due to
Heat transmission branch 41 is connected with heat exchanger 10, at the same the exhaust piping 20 and the battery heating circuit with it is described
Heat exchanger 10 is connected to, therefore heat exchange can be carried out between heat transmission branch 41 and battery heating circuit, thus, work as needs
When heating to battery 3, the second triple valve 200 disconnects engine cooling circuit 40, is connected to heat transmission branch 41 and starts
Heat transmission circuit is formed between the road of the part of machine cooling circuit 40, by between heat transmission circuit and battery heating circuit
Heat exchange realize heating to battery；When needing to cool down battery 3, the second triple valve 200 disconnects heat transmission branch
Road 41 is connected to engine cooling circuit 40, while the first triple valve 100 is connected to battery cooling circuit 30, is cooled back by battery
Road 30 cools down battery 3.As it can be seen that the setting of the second triple valve 200 can control engine cooling circuit 40 and heat transmission branch
