Before introducing the present invention program, first the concrete application scene of the present invention is explained.
It is known that in hybrid power, (the relatively conventional vehicle of high voltage electric part of especially electric hybrid vehicle of oil is significantly
Increasing, radiating is particularly important to it) in vehicle operation, the part such as electromotor, motor all can discharge a few thing heat,
These working heats can improve part own temperature and ambient temperature, leads to part and vehicle performance and work efficiency to be all subject to
Impact.
In order to provide the temperature being suitable for its normal work to parts such as electromotor, motors, vehicle typically can configure a use
In the low-temperature cooling system of cooling, all unit Series to be cooled are connected to the water pipe of uniform diameters, by integrated
Radiator and electric water pump carry out cooling process to each part, and wherein, integrated heat spreader is built-in with coolant, it may include radiating
Device, water tank, fan etc.；Electric water pump independently can be driven by 24V power supply.Cool principle can be understood as：Coolant is through water of radiation
After case carries out heat exchange, temperature reduces, and then exports to electric water pump, enters unified straight under the powered of electric water pump
The water pipe in footpath, cooling successively is serially connected in all parts on water pipe, is finally back to radiator and carries out heat exchange.
According to above-mentioned temperature-fall period, inventor is in practice, it has been found that the requirement to temperature for each part differs greatly, if being
All parts to be cooled are serially connected on caliber identical water pipe it is easy to the temperature that will result in section components is too high or mistake
Low, affect component working efficiency and service life.Meanwhile, this scheme that all parts to be cooled are serially connected in water pipe, to electricity
The requirement of the power of dynamic water pump and lift higher it is also possible to energy dissipation can be caused.Additionally, for being directed to motor vehicle driven by mixed power,
This scheme also can result in the excessive temperature differentials between same part, e.g., by left electric machine controller and right electric machine controller priority
It is connected on water pipe, coolant flows through temperature after left electric machine controller carries out heat exchange and raises, and then flows into right motor control again
Device carries out heat exchange, and the temperature of two electric machine controller entrances is different, leads to cooling-down effect different, and then leads to two motors
The larger temperature difference, the work efficiency of two electric machine controllers of impact and service life occur between controller.
That is, the main cause of impact component working efficiency and service life is, right successively to be connected in series mode
Each part carries out cooling process, is directed to this, embodiments provides solution below.

It is connected in series between described engine controller, parallel-connected induction motors controller unit, electromotor and parallel-connected induction motors unit, formed low
Warm cooling circuit；Coolant in described integrated heat spreader is through described electric water pump export to described coolant cooling circuit, and warp
Described coolant cooling circuit is back to described integrated heat spreader.
In order to solve the problems, such as same part excessive temperature differentials in motor vehicle driven by mixed power, the embodiment of the present invention is using string simultaneously mixed connection
Mode, each part to be cooled is linked together.Wherein, different parts connect in a series arrangement, such as engine controller and
It is connected in a series arrangement between left electric machine controller；Same parts are connected with parallel way, such as left electric machine controller and right motor
It is connected with parallel way between controller.So so that it may the temperature of the coolant of guarantee same parts entrance is essentially identical,
Under identical cooling-down effect, with regard to being avoided that same part the problem of the larger temperature difference it is ensured that the work efficiency of part and use the longevity
Life.
In addition, it is necessary to explanation, engine controller, left electric machine controller, right electric machine controller require relatively to cooling
High, that is, three needs to work at a lower temperature, therefore when arranging coolant cooling circuit, three should be arranged on before loop
Face, i.e. coolant, after electric water pump export, first cools to three, then export again electromotor, left motor,
Right motor carries out heat exchange.Specifically, between engine controller and parallel-connected induction motors controller unit, can as shown in Figure 1 sequentially
Setting, after coolant also can be made first to flow through parallel-connected induction motorses control unit, then flows into engine controller.Similar, electromotor
And parallel-connected induction motors unit between, can sequentially arrange as shown in Figure 1, after coolant also can be made first to flow through parallel-connected induction motors unit, then flow
Enter electromotor, and then be back to integrated heat spreader.In this regard, the embodiment of the present invention is all not specifically limited.
, through scheme shown in example 1 above so that it may ensure that left and right electric machine controller enters taking left and right electric machine controller as a example
The coolant temperature of mouth is essentially identical, if the current temperature of left and right electric machine controller (refers specifically to part through before processing of lowering the temperature
Temperature) essentially identical, then the two through cooling process after temperature also can be essentially identical, that is, be not in asking of excessive temperature differentials
Topic.If but the two current temperature just differs larger, then carrying out still occurring the temperature difference after cooling process through embodiment 1 scheme
Larger problem.For this reason, the embodiment of the present invention additionally provides low-temperature cooling system embodiment 2, specifically can be found in and illustrate shown in Fig. 2
Figure.
On the basis of scheme shown in Fig. 1, low-temperature cooling system may also include four temperature sensors and two distributing valves.
Wherein, described left electric machine controller, the temperature of right electric machine controller, left motor and right motor are monitored in four temperature sensors respectively
Degree, and temperature signal is transmitted the entire car controller 111 to outside described low-temperature cooling system；Two distributing valves are connected on institute respectively
State the import of parallel-connected induction motors controller unit and parallel-connected induction motors unit, for the instruction adjustment input according to described entire car controller
To left electric machine controller, right electric machine controller, left motor, the coolant of right motor flow.
Still, in the present embodiment, taking left and right electric machine controller as a example except the mode that can connect in parallel it is ensured that a left side,
Outside the coolant temperature of right electric machine controller entrance is essentially identical, also (can be referred specifically to by the two Current Temperatures of monitoring
The temperature being part through before processing of lowering the temperature), real-time adjustment flow into the coolant rate of the two mode it is ensured that the two through cooling at
Temperature after reason is essentially identical.
It should be noted that four temperature sensors can be respectively and independently arranged at left electric machine controller, right motor control
Outside device, left motor, the temperature of right motor, i.e. temperature sensor is arranged with corresponding isolation of components formula to be monitored；Or, temperature
Sensor can also be integrated in corresponding components interior to be monitored, and (shown in Fig. 2 is exactly the portion being integrated with temperature sensor
Part).The present invention can be not especially limited to this, as long as can measure that the temperature signal of left electric machine controller, right motor control are obtained
The temperature signal of device, the temperature signal of left motor, the temperature signal of right motor, and transmit to have process and control ability whole
Vehicle controller HCU (Hybrid Control Unit, hybrid power full-vehicle control unit).
The implementation of corresponding this low-temperature cooling system, present invention also offers a kind of sub-cooled method embodiment 1,
Specifically can be found in flow chart shown in Fig. 3, it may include：
Step 201, receives left electric machine controller temperature signal, the right electric machine controller temperature letter of temperature sensor transmission
Number, left motor temperature signal and right motor temperature signal.
Step 202, determines first point according to described left electric machine controller temperature signal and right electric machine controller temperature signal
Join the first flow apportioning cost of valve 109, and described first flow apportioning cost is sent to described first distributing valve, so that described
One distributing valve is diverted to the coolant of left electric machine controller and right electric machine controller according to the adjustment of described first flow apportioning cost
Flow.
Step 203, determines the second of the second distributing valve 110 according to described left motor temperature signal and right motor temperature signal
Flow apportioning cost, and described second flow apportioning cost is sent to described second distributing valve so that described second distributing valve according to
Described second flow apportioning cost adjustment is diverted to the flow of the coolant of left motor and right motor.
In conjunction with schematic diagram shown in Fig. 2, it is current that the corresponding temperature sensor of left electric machine controller gathers left electric machine controller
Temperature, temperature value is added in temperature signal and sends to HCU；Correspondingly, the corresponding temperature sensor of right electric machine controller
The current temperature of right electric machine controller can be gathered send to HCU, so, HCU can determine in parallel according to this two temperature signals
Flow apportioning cost (i.e. first above of the distributing valve (i.e. the first distributing valve above) of motor controller units entrance
Flow apportioning cost), and then control input is to the flow of left electric machine controller and the coolant of right electric machine controller.Detailed process can
It is presented as：
Whether HCU judges to be consistent between left electric machine controller temperature and right electric machine controller temperature, and (herein being consistent can
To be interpreted as：Temperature value is equal；Or temperature value is all in a preset range, that is, the temperature difference is less than specified range)：
If the two is consistent, illustrate that electric machine controller, right electric machine controller input equivalent coolant are so that it may ensure to the left
The two is not in the larger temperature difference after processing through cooling, and now, corresponding flow apportioning cost can be regarded as 1:1；
If the two is not inconsistent, illustrate according to 1:1 coolant exporting engine controller is input to left motor control
When device, right electric machine controller carry out cooling and process, the two it is possible that the problem of excessive temperature differentials, now, can according to the two
Temperature is than the flow-rate ratio of setting coolant.Generally, temperature and flow can be considered a kind of proportional relation, and that is, temperature is higher,
More need to input more coolant, after cooling process, so just can reduce the temperature difference between the two.
HCU sets after the flow apportioning cost of the first distributing valve according to the Current Temperatures of left and right electric machine controller, you can to
First distributing valve output control signal, so that the coolant that engine controller is exported by the first distributing valve according to the control of HCU
Correctly it is diverted to left electric machine controller and right electric machine controller.So, the coolant after shunting is carried out to left and right electric machine controller
After cooling is processed, you can ensure that the two is not in the larger temperature difference.In addition, it is necessary to explanation, coolant can be in left and right motor
The exit of controller is converged, and then carries out cooling process to electromotor, parallel-connected induction motors unit successively again.Wherein, parallel-connected induction motorses
The processing procedure of unit can refer to the introduction to parallel-connected induction motors controller unit processing procedure above, and here is omitted.
In addition, it is necessary to explanation, the coolant shunting cooling processing procedure of parallel-connected induction motors controller unit, parallel-connected induction motorses
The coolant shunting cooling processing procedure of unit, the two can sequentially execute as shown in Figure 3, also can first parallel-connected induction motors unit be carried out
Shunting cooling, then parallel-connected induction motors controller unit is carried out with shunting cooling, execution sequence depends primarily on parallel-connected induction motorses controller
Unit, the parallel-connected induction motors unit position in coolant cooling circuit.As shown in Fig. 2 coolant first flows through parallel-connected induction motorses controller
Unit, passes through parallel-connected induction motors unit, therefore according to order shown in Fig. 3, the two can be carried out shunting cooling process.In this regard, can basis
Depending on practical situations, the present invention is simultaneously not especially limited.
Can solve the problems, such as that the same part temperature difference is larger using low-temperature cooling system embodiment 1,2 above, in actual behaviour
When making, after processing in order to avoid cooling, the too high or too low phenomenon of part temperatures occurs, the part temperatures after processing through cooling are still
It is unsatisfactory for the temperature of its normal work.For this reason, embodiments providing low-temperature cooling system embodiment 3, specifically can be found in
Schematic diagram shown in Fig. 2.
On the basis of scheme shown in Fig. 1, low-temperature cooling system may also include six temperature sensors, six temperature sensing
Device monitors described engine controller, left electric machine controller, right electric machine controller, electromotor, left motor and right motor respectively
Temperature, and temperature signal is transmitted the entire car controller to outside described low-temperature cooling system；Described electric water pump is used for according to institute
State the flow of the instruction adjustment output of entire car controller to the coolant of described coolant cooling circuit.
That is, (referring specifically to part through cooling by the Current Temperatures of each part of temperature sensor real-time monitoring
Temperature after process), and compared with the temperature range of part normal work, judge whether the part after cooling process temperature
Spend too high or too low phenomenon.If there is, then the coolant rate that explanation cooling uses when processing is mismatched with current working, therefore
The coolant rate of electric water pump export can be adjusted according to the scheme that the present embodiment provides, detailed process can be found in low shown in Fig. 4
The flow chart of warm cooling means embodiment 2, it may include：
Step 301, after the process that part carried out cool, receives the engine controller temperature of temperature sensor transmission
Signal, left electric machine controller temperature signal, right electric machine controller temperature signal, generator-temperature detection signal, left motor temperature signal,
With right motor temperature signal.
Step 302, according to engine controller, left electric machine controller, right electric machine controller, electromotor, left motor and the right side
The temperature signal of motor adjusts electric water pump export to the flow of the coolant of coolant cooling circuit.
In actual applications, after one part of each pair carries out cooling process, you can by the corresponding temperature sensor of part
Gather the temperature after its cooling to transmit to HCU, the temperature model whether with part normal work for the temperature after this cooling is judged by HCU
Enclose and be consistent：
If being consistent, continuing next part is carried out the temperature after the process that cools, and obtaining widget cooling and carrying out
Judgement is compared, and till last part having judged in coolant cooling circuit, or until finds coolant cooling circuit
Till the part that after middle cooling, temperature is not inconsistent with normal working temperature scope；
If be not inconsistent, illustrate that the coolant rate of electric water pump export and current working mismatch, if part cooling
Temperature afterwards is too high compared with the temperature range of its normal work, then the flow of the coolant of explanation electric water pump export is less,
More coolants are needed to carry out cooling process to coolant cooling circuit；If the temperature after part cooling and its normal work
Temperature range is compared too low, then the flow of the coolant of explanation electric water pump export is more, needs less coolant to low temperature
Cooling circuit carries out cooling process.HCU can adjust the coolant rate of electric water pump export accordingly, to ensure coolant cooling circuit
In each part through cooling process after can meet its requirement within the temperature range of work.
It should be noted that when HCU determines the coolant rate adjusted value of electric water pump, except part cooling will be considered
Outside difference between rear temperature and the temperature range of its normal work, preferably it is also possible to consider part position in the loop.
For example, each part position in the loop is set according to schematic diagram shown in Fig. 2, if HCU detection judges parallel-connected induction motorses controller list
Temperature after unit's cooling is higher than the temperature range that its normal work needs, and adjusts the cooling of electric water pump export in this case
Flow quantity；With in reverse Fig. 2, (i.e. coolant first flows through parallel connection to the order of engine controller and parallel-connected induction motors controller unit
Motor controller units, then flow into engine controller), if now HCU detects and judges that parallel-connected induction motors controller unit cools down
Temperature afterwards is higher than the temperature range that its normal work needs, and adjusts the cooling liquor stream of electric water pump export in this case
Amount.Because in the previous case, coolant has carried out heat exchange with engine controller, exports parallel-connected induction motorses controller list
The coolant temperature of first import has raised, and in latter event, coolant is directly output to electricity in parallel after electric water pump
Machine controller unit inlet, now coolant do not carry out heat exchange with any part, temperature does not raise yet, therefore according to temperature difference
During value adjustment coolant rate, even if the temperature gap in the case of two kinds is identical, the previous case needs relative to latter event
Increased coolant rate will lack.
