System, the first water pump, heater HVH and heater cores, which join end to end, constitutes partial circulating circuit A, on the pipeline of partial circulating circuit A
Be provided with the first triple valve, the first triple valve wherein two it is logical connect with the pipeline in partial circulating circuit, it is another lead to it is cold with motor
But circuit B connects, and the second triple valve, the logical pipe with cooling circuit B of the two of the second triple valve are provided on the cooling circuit B of motor
Road connects, it is another it is logical connect with partial circulating circuit A, the first and second triple valve controls heater HVH and individually heats partial circulating circuit A
Or the cooling circuit B systemic circulation circuit C in series of heating partial circulating circuit A and motor.
In above scheme, by the control of the first and second triple valve, heater HVH can respectively to two circuits into
Two demands of motor warming-up and compartment heating, save the cost are realized in row heating.
Detailed description of the invention

Specific embodiment
As shown in Figure 1, a kind of warm air system with dual mode coolant loops, the first water pump 1, heater HVH2 and warm wind
Core 3, which joins end to end, constitutes partial circulating circuit A, and the first triple valve 4, the first triple valve 4 are provided on the pipeline of partial circulating circuit A
Wherein two it is logical connect with the pipeline in partial circulating circuit, it is another lead to connect with the cooling circuit B of motor 5, the cooling circuit of motor 5
It is provided with the second triple valve 6 on B, the two of the second triple valve 6 are logical to connect with the pipeline of cooling circuit B, another logical with partial circulating time
Road A connects, the first and second triple valve 4,6 control heater HVH2 individually heat partial circulating circuit A or heating partial circulating circuit A with
The systemic circulation circuit C cooling circuit B of motor 5 in series.
When the first triple valve 4 one it is logical be connected to partial circulating circuit A, one leads to and is connected to cooling circuit B, in addition an on-off is opened
When, as shown in figure 3, partial circulating circuit A and cooling circuit B systemic circulation circuit C in series, heater HVH2 are giving air-conditioning
While warm air system heats, the coolant liquid being heated flows through motor 5, will heat inside motor, realizes the warming-up of motor 5；To
Motor 5 start after, motor 5 will generate heat in the course of work of itself, do not needed at this time heater HVH2 again to
Motor 5 provides warming-up and services, so the wherein two logical pipeline connection with partial circulating circuit A of the first triple valve 4, in addition one is logical
It is disconnected with cooling circuit B, the one of the second triple valve 6 is logical to be connected to partial circulating circuit A, as shown in Fig. 2, heater HVH2 can only give
Air conditioning warm air system heating, be embodied as the purpose of cabin heat supply, due to the first triple valve 4 be disconnected with cooling circuit B, so
Heat does not reach cooling circuit B.By the control of the first and second threeway 4,6, a heater HVH2 can respectively be returned two
Road is heated, and is realized two demands of motor warming-up and compartment heating, is simplified the design of system, improve the reliable of system
Property, the degree of coupling of system is improved, realizes the efficient utilization of energy.
In order to improve temperature-responsive, even if the thermal energy of partial circulating circuit A can be rapidly transferred to or end in cool back
