Bag internal duct has sufficiently large contact area with battery pack, so as to preferably complete the heat exchange with battery pack.
When battery bag temperature is higher, the heat transfer process of circulating liquid：The circulating liquid flowed out from radiator 1-2
It is divided into two-way, the first via flows into electric machine controller 3-1 by the first pipeline 4-1, water circulating pump 2-1, the second pipeline 4-2, absorbs
The heat of electric machine controller 3-1 associated components diverging, temperature is raised, then flows into motor 3-2, absorbs heat inside motor 3-2
Amount, circulating liquid temperature continues to raise；Flow through the 6th pipeline 4-6 and the second three-way valve 2-3, radiator inlet pipeline 4-9 again
Secondary entrance radiator 1-2 is circulated；Second tunnel circulating liquid from radiator 1-2 come out after by second circulation water pump 2-6, cold
But circulation line 4-5, battery bag inlet pipeline 4-7 enter in battery bag 5, the heat with absorbing battery bag 5, temperature rise, then
The second three-way valve 2-3, radiator inlet pipeline 4-9 are flowed through into radiator 1-2.

Temperature is 30 DEG C afterwards, and the temperature for flowing through motor 3-2 is 45 DEG C, finally flows into radiator 1-2 and is radiated again；Second tunnel is followed
Temperature is 20 DEG C when ring liquid comes from radiator 1-2, and it is 35 DEG C to flow through temperature after battery bag 5, finally flows into radiator 1-2 again
Radiated.Whole process is the heat that first via circulating liquid absorbs that electric machine controller and motor are produced, and the second tunnel is followed
The heat of ring liquid absorption battery bag.
S3, radiator fan power adjusting：
When the temperature of electrokinetic cell is relatively low needs heating, entire car controller monitors battery pack and the temperature of motor in real time, is dissipating

Pass through battery bag 5, if the temperature of battery in the temperature range of setting, the temperature of motor also in the temperature range of setting,
Radiator fan 1-1 need not then be opened, it is only necessary to carry out natural heat dissipation with radiator 1-2；Do not open scattered when motor temperature is higher
Hot-air fan is difficult to reduce in radiator in the case of the temperature of circulating liquid, opens a radiator fan or two radiator fans
Circulating liquid is cooled down, it is ensured that the temperature of motor reaches rational working range.
When the temperature of electrokinetic cell is higher needs radiating, then a radiator fan 1-1 or two radiator fans are opened
1-1, if the temperature of electrokinetic cell in the temperature range of setting, motor 3-2 temperature also in the temperature range of setting, then without
Radiator fan 1-1 power need to be increased；When the temperature of circulating liquid is by absorbing battery bag, motor 3-2 and electric machine controller 3-1
