When there is heating request (i.e. warm wind is asked) in compartment, start heating component 18, to pass through the cooling flow after heating
Compartment is heated through heater cores 20.Specially：By the first port 21A and second port of the 4th adjustable triple valve 21
21B is connected, and third port 23C and the 4th port the 23D conducting of four-way valve 23, third electronic water pump 17 start, and start speed governing work
Make, heating component 18 adjusts its heating power according to the exit water temperature of heater cores 20 and the demand temperature of driver, to real
Existing compartment heat-production functions.
In other words, the separate refrigeration and list in compartment (cockpit) can be implemented separately in the heat management system of the electric vehicle
Only heat-production functions, refrigeration and heat-production functions while can also realizing compartment.When the function of realizing chiller compartment and heating simultaneously
When, above-mentioned two separate refrigeration only need to be adjusted simultaneously and heat-production functions need the component of work to be worked, and specifically described
As above, details are not described herein again.
In short, the heat management function of the motor and electric machine controller of foregoing description, OBC, battery pack and compartment etc. is single
One function then adjusts associated components and works at the same time when there is function while when demand, and specific operation process is as above, this
Place repeats no more.
Further, when battery pack 12 and compartment have heating to ask simultaneously：
1) by the first port 21A of the 4th adjustable triple valve 21 and second port 21B conductings, by the first end of four-way valve 23
Mouthful 23A and the 4th port 23D conductings to realize being connected in series with for heater cores 20 and battery pack 12, while starting heating component
18 and third electronic water pump 17, then heating component 18 (PTC) first flow into heater cores 20 after heating cooling water, by heater cores
Water temperature reduces after 20 outflows, then flows into battery pack 12.It should be noted that the water inlet temperature when battery pack 12 is less than warm wind core
It is more reasonable using this pattern when the demand of 20 water inlet of body.Or
2) the 4th adjustable triple valve 21 is adjusted between 21C mouthfuls of second port 21B and third end, to realize heater cores
20 and battery pack 12 be connected in parallel, can also realize the cooling water ratio of different heater cores 20 and battery pack 12, start simultaneously
Heating component 18 and third electronic water pump 17, to be heated.It should be noted that working as the water inlet temperature of battery pack 12 and warming up
It is more reasonable using this pattern when the temperature requirements of 20 water inlet of wind core are close.
