Description

Cooling device for hybrid vehicle and its control method {Cooling module for HEV vehicle and method for controlling the same}

The present invention relates to a cooling device for a hybrid vehicle and a control method thereof, and more particularly, to a hybrid vehicle cooling device and a control method for allowing a radiator arranged in two or more rows including a condenser to be easily cooled using ion wind. It is about.

Hybrid vehicles not only generate significantly higher heat than internal combustion engine vehicles, but also require very high cooling specifications to maintain the durability of electrical components, including motors.

To this end, a conventional hybrid vehicle cooling module is composed of a condenser, a full length radiator, an engine radiator, a cooling fan, and the like, in particular, a full length radiator that is responsible for cooling the electric parts (driving motors, etc.) together with the condenser. It is located in front of the engine radiator.

Referring to Figure 5 attached to the arrangement for each configuration of the cooling module, the electric field radiator 12 is disposed at the foremost of the components of the cooling module 10, and maintains a predetermined distance along the back The condenser 14 and the engine radiator 16 are arranged in sequence, and the cooling fan 18 for suctioning the cooling wind is disposed at the rear.

The electric field radiator 12 and the condenser 14 perform an independent cooling operation. The condenser 14 forms a refrigeration system together with a compressor and an evaporator to perform a cooling function for a vehicle interior, and the electric field radiator 12 In addition to the motor for driving the vehicle serves to cool the coolant that is heat exchanged from the junction box, various batteries and the controller.

Of course, the engine radiator 16 serves to cool the engine coolant.

In the arrangement of the configuration of the conventional cooling module, there is a limit to increase the size and capacity of the condenser 14 and the engine radiator 16, including the full length radiator 12 due to the limited installation space, As shown in FIG. 6, the cooling wind is hydraulically cooled in front of the condenser arranged at the rear of the electric field radiator 12 as the speed of the cooling wind decreases as it passes through the overlapping region, which is a space between the components 12, 14, and 16. The biggest problem is that cooling performance falls, such as the temperature of 14 and the engine radiator 16 rising.

In particular, when the cooling fan 18 disposed behind the engine radiator is driven, cooling air, which is outside air sucked by the cooling fan 18, causes the condenser 14 and the engine radiator 16, including the electric field radiator 12. Although it passes through and cools, as shown in FIG. 7, both end portions of each of the components 12, 14, and 16 become dead zones without cooling wind, which causes a decrease in cooling performance.

In other words, as the engine radiator is disposed at the rear, the engine cooling performance may be deteriorated due to the decrease in the wind speed of the cooling wind, and the cooling wind speed only increases around the fan even if the power of the cooling fan is increased, and the speed distribution of the cooling wind is increased. There is a problem that the cooling performance for the dead zone is poor because it is nonuniform.

The present invention has been made in view of the above, and is provided by means of separately providing a means for dissipating ion wind in a radiator arranged in two or more rows including a condenser, thereby dissipating the ion wind together with the cooling air by outside air, thereby cooling SUMMARY OF THE INVENTION An object of the present invention is to provide a cooling device for a hybrid vehicle and a method of controlling the same, which can easily cool down to a dead zone area where no wind is reached.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, in order to help the understanding of the present invention, a brief description of the principle of generating the ion wind with reference to FIG. 4 shows that a positive corona electrode ionizing air molecules such as nitrogen and a collector electrode serving to pull ionized molecules are opposed to each other. In this case, when a voltage is applied to the positive corona electrode, the ions move from the discharger side of the positive corona electrode to the negative collector electrode, and at the same time, the neutral air molecules around them move together to generate the ion wind. .

The present invention is to cool the condenser and engine radiator by using the cooling wind, and to cool the dead zone area of the electric field radiator and engine radiator by using the ion wind, thereby improving the cooling performance for the condenser and engine radiator, including the electric field radiator In particular, the main point is that even cooling is achieved by excluding the dead zone area where the cooling air of the engine radiator does not reach.

To this end, the cooling module 10 according to the present invention, unlike the three-row arrangement structure in which the electric field radiator 12, the condenser 14, and the engine radiator 16 are sequentially arranged, the electric field radiator 12 at the foremost And the condenser 14 are arranged side by side in the left and right direction, and the two-row arrangement structure in which the engine radiator is arranged behind the electric field radiator 12 and the condenser 14 is improved, and the cooling wind in the rear region of the engine radiator 16 is improved. The cooling fan 18 for sucking the water is arranged.

At this time, since there is a limit to increasing the capacity of the cooling fan 18, since the cooling fan 18 cannot cover the entire rear region of the engine radiator 16, one side of the rear side of the engine radiator 16 is a cooling fan. It becomes the dead zone area extended longer than the left and right width of (18).

Therefore, the frontmost condenser 14 is in a state arranged in line with the cooling fan 18 with the engine radiator 16 interposed therebetween, and is condensed by the cooling wind sucked by the driving of the cooling fan 18. 14 is cooled and a part of the engine radiator 16 (part except the dead zone area of the engine radiator coinciding with the rear of the full length radiator) is cooled.

Here, the ion wind generating means 20 for dissipating ion wind in the overlapping region which is a space between the electric field radiator 12 and the engine radiator 16 and one side of the engine radiator 16, that is, the dead zone region, is provided. Negative collector electrodes are disposed.

The ion wind generating means 20 includes a plurality of positive corona electrodes 22 disposed in front of the full length radiator 12 and a plurality of overlapping regions which are spaces between the full length radiator 12 and the engine radiator 16. A first negative collector electrode 23 and a second negative collector electrode 24 disposed behind the dead zone region of the engine radiator 16.

Preferably, the plurality of positive corona electrodes 22, as well as the first and second negative collector electrodes 23 and 24 are attached to the support 21 having a lattice network structure.

In this case, a voltage device 27 for applying a current is connected to the positive corona electrode 22, and a first switch 25 is connected to a conductive line connecting the voltage device 27 and the first negative collector electrode 23. The second switch 26 is mounted in the conductive line connecting the voltage device 27 and the second negative collector electrode 24.

Here, the method for controlling the cooling device for a hybrid vehicle of the present invention based on the above configuration is as follows.

When the cooling fan is turned on or the cooling fan 18 is operated in accordance with the temperature of the cooling water, the cooling air caused by the external air suction action of the cooling fan 18 flows into the condenser 14 and the engine radiator 16 behind it. Flows in, and the condenser 14 and the engine radiator 16 are cooled by the cooling wind.

Preferably, when the coolant temperature of the engine radiator 16 is equal to or greater than the first reference temperature that is the operating temperature of the cooling fan, the cooling fan is operated to introduce cooling air, so that the condenser 14 and the engine radiator 16 are provided only by the cooling air. Can be cooled easily.

At this time, the cooling wind reaches the dead zone of the engine radiator 16 which is coincident with one side of the engine radiator 16, that is, the rear of the electric field radiator 12, but the temperature of the engine coolant may rise because it does not completely fall. have.

Therefore, if the coolant temperature of the engine radiator 16 is equal to or greater than the second reference temperature that is the operation standard of the ion wind generating means 20, the positive corona electrode disposed in front of the electric field radiator 12 in the voltage device 27. A current is applied to the 22, and at the same time, the ion wind is emitted from the positive corona electrode 22 toward the second negative collector electrode 24 disposed behind the dead zone of the engine radiator 16.

That is, when a voltage is applied to the positive corona electrode 22, the ions move from the discharger side of the positive corona electrode 22 toward the second negative collector electrode 24, and at the same time, the neutral air molecules around the same move when the ions move. This causes ionic wind.

As such, when the coolant temperature of the engine radiator 16 is equal to or greater than the second reference temperature, the engine radiator 16 is cooled by the cooling wind caused by the operation of the cooling fan 18, and the engine radiator 16 is affected by the ion wind. Cooling is performed to the dead zone area of, so that the cooling efficiency for the engine radiator 16 can be further increased.

On the other hand, the electric field radiator 12 is cooled only with ion wind.

That is, the positive corona electrode 22 disposed in front of the electric field radiator 12 in the voltage device 27 when the cooling water temperature of the electric field radiator 12 is equal to or higher than the reference temperature which is the operation standard of the ion wind generating means 20. An electric current is applied to the electric current, and at the same time, the ion wind is emitted from the positive corona electrode 22 toward the first negative collector electrode 23 disposed in the overlapping area, which is a space between the electric field radiator 12 and the engine radiator 16.

That is, when a voltage is applied to the positive corona electrode 22, the ions move from the discharger side of the positive corona electrode 22 toward the first negative collector electrode 23, and at the same time, the neutral air molecules around the same move when the ions move. This causes ionic wind.

As such, when the cooling water temperature of the electric field radiator 12 is equal to or higher than the reference temperature, ion wind is emitted, so that the electric field radiator 12 may be cooled by the ion wind alone.
