Detailed description of the invention
For enabling above-mentioned purpose of the present utility model, feature and advantage more become apparent, and are described in detail specific embodiment of the utility model below in conjunction with accompanying drawing.
For in the cooling system of automobile dynamic system, generally realize refrigerating function by refrigerant fluid (such as cooling water expansion tank) and radiating part.Radiating part has generally comprised radiator (as low-temperature radiator, for dispelling the heat to power electronics box, motor), condenser, other heat dissipation equipment and fans etc.Due to the restriction of inner space of vehicle, often very limited for the space of installing radiating part.
As described in the background art, in existing cooling system, cooling water flow out of the temperature after motor higher, make the heat radiation load of radiator comparatively large and affect radiating effect.If ensure the radiating effect of radiator, then need such as to improve its heat-sinking capability by the mode increasing its size, but so, size due to radiator becomes large, when installing space is certain, by the installing space of miscellaneous part in extruding radiating part, increase assembly difficulty.
For above-mentioned various problem, the utility model embodiment provides a kind of for automobile, the particularly cooling system of the power system of new-energy automobile, with reference to Fig. 1, power electronics box 11 and motor 12 is included in power system, wherein power electronics box 11 also claims automatically controlled, works for managing motor 12, and its function mainly comprises energy pipeline function (carrying out power division, Power Limitation and charging to motor to control), drive and control of electric machine function etc.Cooling system has cooling loop, and cooling loop has the total road L of cooling, and the first branch road L1 parallel with one another, the second branch road L2.The two ends (entrance side, outlet side) of the first branch road L1, the second branch road L2 are communicated with the total road L of cooling respectively, and the first branch road L1 forms the first loop with the total road L of cooling, and the second branch road L2 forms second servo loop with the total road L of cooling.
Radiating part 20 and power electronics box 11 are series at and cool in total road, and motor 12 is arranged in the first branch road L1.Refrigerant fluid (such as cooling water expansion tank) flows through radiating part 20, power electronics box 11, first branch road L1 and/or the second branch road L2 successively, then gets back to radiating part 20, and circulates according to this.
Wherein, radiating part 20 comprises radiator 21 (as low-temperature radiator) and fan 22, for dispelling the heat to power electronics box, motor.Wherein, radiator 21 side is located at by fan 22.In the present embodiment, the refrigerant fluid in cooling loop flows through radiator 21 and is cooled by radiator 21, and 22, fan can carry out auxiliary heat dissipation to the refrigerant fluid flowing through radiator 21.
Wherein, the normal working temperature of power electronics box 11 is generally 70 DEG C ~ about 75 DEG C, requires that the cooling-liquid temperature flowing into power electronics box 11 is no more than 65 DEG C; The normal working temperature of motor 12 is generally 85 DEG C ~ about 90 DEG C, requires that the cooling-liquid temperature flowing into motor 12 is no more than 75 DEG C.Visible, the operating temperature of power electronics box 11 will lower than the operating temperature of motor 12, when refrigerant fluid is after radiator cooling, if arrange refrigerant fluid first to flow through motor 12, flow into power electronics box 11 again, then can cause the coolant-temperature override flowing into power electronics box 11, fully can not dispel the heat to power electronics box 11, affect it and normally work.
Therefore in order to ensure the operating temperature of power electronics box 11, refrigerant fluid being set after being cooled by radiating part 20, first flowing through power electronics box 11, again flow direction motor 12.
In the present embodiment, as Fig. 1, refrigerant fluid can flow into the first branch road L1, the second branch road L2 after flowing through radiating part 20, power electronics box 11 successively, then flows back into the total road L of cooling and again arrive radiating part 20.Exactly, refrigerant fluid is cooled to suitable low temperature after flowing through radiating part 20, the cryogenic liquid flowed out flows through power electronics box 11, dispels the heat to power electronics box 11, then the first branch road L1, the second branch road L2 can be entered respectively, heat-producing device in these two branch roads is dispelled the heat, and radiating part 20 is again flow back into after outflow first branch road L1, the second branch road L2, carry out next circulation.
In the present embodiment, because motor is arranged in the first branch road L1, refrigerant fluid flows into the first branch road L1, the second branch road L2 after flowing through power electronics box 11, second branch road L2 can shunt the refrigerant fluid flowing through motor 12, reduce the coolant flow rate flowing through motor 12, motor 12 therefore can be avoided to be cooled excessively and to be reduced to below operating temperature.
In the present embodiment, for ensureing the radiating efficiency of radiating part 20, second branch road L2 is only cooling duct, wherein do not arrange any heatable equipment, the cooling-liquid temperature so flowed out from the second branch road L2 can not raise again, thus reduces the cooling-liquid temperature flowing back into radiating part 20, reduce the heat radiation load of radiating part 20, ensure its radiating efficiency, make refrigerant fluid can flow into power electronics box 11 again after fully being cooled, reduce the cooling risk of power electronics box 11.
Further, continue with reference to Fig. 1, the cooling system of the present embodiment also comprises control cock 30, is arranged in the first branch road L1, the second branch road L2, for controlling the opening and closing of the first branch road L1, the second branch road L2.
Wherein, control cock 30 is triple valve, and be positioned at the first branch road L1, the second branch road L2 and the connection location cooling total road L, triple valve comprises three adaptor unions, is communicated with respectively with cooling total road L, the first branch road L1, the second branch road L2.The opening and closing of the first branch road L1, the second branch road L2 is controlled by triple valve.
When motor 12 does not need cooling, can control the first branch road L1 by triple valve and close, refrigerant fluid does not flow into the first branch road L1, but all directly flow back into radiating part 20 from the second branch road L2.Like this, on the one hand, concerning motor 12, its heat liquid that can not be cooled is taken away, thus ensures its operating temperature; On the other hand, concerning radiating part 20, refrigerant fluid is not owing to flowing through motor 12, temperature when it enters radiating part 20 is lower, the heat radiation load of radiating part 20 is less, and radiating part 20 can be dispelled the heat fully to refrigerant fluid, and then ensures the normal cooling of power electronics box 11.
When under special circumstances, such as, when automobile is in the anxious operating condition accelerated or suddenly slow down, motor 12 is in comparatively large load operation state, dispel the heat larger, now the cal val of motor 12 is higher, cooling requirement is comparatively large, and therefore can control the second branch road L1 by triple valve and close, refrigerant fluid does not flow into the second branch road L2, but all to enter in the first branch road L1 and to flow through motor 12, motor 12 is cooled fully.
Wherein, control cock 30 also can be used for regulating the flow of refrigerant fluid flowing through the first branch road L1, the second branch road L2.When motor 12 needs heat radiation, control cock 30 can regulate the coolant flow rate flowing through motor 12, thus carries out suitable heat radiation to motor 12, avoids the refrigerant fluid owing to flowing through motor 12 too much to cause motor 12 temperature to be in below operating temperature.

Wherein, control unit is heat management control unit, for accepting the temperature signal of motor 12.Heat management control unit accessible site, in on-board air conditioner controller, also can be integrated in HCU (Engine ECU of similar traditional vehicle) inner.
Assumed temperature T0 is the cooling initial temperature of motor 12, and namely motor 12 is lower than not needing cooling during temperature T0; Suppose when the temperature of motor 12 is higher than T1, cooling requirement is comparatively large, needs refrigerant fluid all to flow through motor 12.So:
As the actual temperature T < T0 of motor 12, heat management control unit sends the first signal to control cock 30, and makes control cock 30 close the first branch road L1, opens the second branch road L2;
As the actual temperature T > T1 of motor 12, heat management control unit sends secondary signal to control cock 30, and makes control cock 30 open the first branch road L1, closes the second branch road L2;
When the actual temperature T of motor 12 is between T0 and T1, namely during T0 < T < T1, heat management control unit sends the 3rd signal to control cock 30, and makes control cock 30 open the first branch road L1, the second branch road L2 simultaneously.Now, carry out the aperture of regulating three-way valve according to the temperature of motor 12, control the assignment of traffic of the first branch road L1, the second branch road L2, the temperature of motor 12 is higher, and the flow of the first branch road L1 is larger.
In other embodiments, open and-shut mode and the aperture of control cock also can be judged by the real-world operation power (horsepower output) of motor.
In other embodiments, also can arrange and two control cock are located in the first branch road, the second branch road respectively, control the opening and closing of the first branch road, the second branch road respectively.The work of two control cock can be controlled by stepping motor, PWM or LIN bus equally.
As Fig. 1, cooling system also comprises water pump 40, is series at cools in total road L with power electronics box 11, radiating part 20, and namely water pump 40 is also positioned at outside the first branch road L1, the second branch road L2, for providing power to the flowing of refrigerant fluid in whole cooling system.Wherein, refrigerant fluid is pumped in the effect of water pump 40, and refrigerant fluid is flowed in cooling loop, and water pump 40 can be arranged in any position cooling total road L.Along the flow direction of refrigerant fluid, water pump 40 is located between the entrance side of the outlet side of radiating part 20 and the first branch road L1, the second branch road L2 by the present embodiment.Particularly, water pump 40 can be located between the outlet side of radiating part 20 and the entrance side of power electronics box 11.
Cooling system also comprises expansion tank 50, and expansion tank 50 is positioned at outside cooling loop, but is communicated with cooling loop, fills certain refrigerant fluid, but do not fill in expansion tank.The effect of expansion tank 50 has two: first, refrigerant fluid flows in cooling loop, along with temperature rising, cubic expansion occurs, cause the pressure in cooling loop to raise, expansion tank 50 can utilize its segment space not filling refrigerant fluid to absorb volume and the pressure of the increase because refrigerant fluid expands; Second, in cooling-liquid cycle, if the refrigerant fluid in cooling loop is very few, pressure then in cooling loop can reduce, between expansion tank 50 and cooling loop, mineralization pressure is poor, thus the refrigerant fluid in expansion tank 50 is squeezed in cooling loop, that is, the refrigerant fluid in expansion tank 50 can play the effect of liquid feeding and fluid infusion to the refrigerant fluid in cooling loop.
In the present embodiment, expansion tank 50 is positioned at outside cooling loop, and refrigerant fluid wherein, except when liquid feeding and fluid infusion, does not participate in the cooling circulation of the first loop, second servo loop.

In other embodiments, power electronics box, motor also can replace with other portions to be cooled, to make this cooling system for the cooling of other equipment.Such as power electronics box is replaced with the first portion to be cooled, motor is replaced with the second portion to be cooled, then the operating temperature in the first portion to be cooled will lower than the operating temperature in the second portion to be cooled.Wherein, the first portion to be cooled, the second portion to be cooled can be the equipment that any one in power system or automobile needs cooling.
The utility model also provides a kind of automobile dynamic system comprising above-mentioned cooling system, and automobile dynamic system operationally, first judges that described motor is the need of cooling:
When motor does not need cooling, controlled cooling model liquid does not flow through motor, the heat of the motor liquid that can not be cooled is taken away, thus ensures its operating temperature;
When motor needs cooling, control flow check flows through motor through a part of refrigerant fluid of power electronics box, makes motor obtain suitable cooling.
Further, can also judge the workload of motor: the workload of motor is larger, control flow check is more through the refrigerant fluid of motor.That is, control system regulates the coolant flow rate flowing through motor according to the workload of motor, thus carries out suitable heat radiation to motor, avoids the refrigerant fluid owing to flowing through motor too much to cause motor temperature to be in below operating temperature.
Wherein, when automobile emergency acceleration, urgency are slowed down, all motor can be flowed through through the refrigerant fluid of power electronics box by control flow check.When this is owing to accelerating when automobile emergency, suddenly slowing down, motor is in larger cooling requirement, and now controlled cooling model liquid all flows through motor, to carry out motor fully effectively dispelling the heat, avoids the temperature of motor too high, ensures that it normally works.
