Description

Cooling module for vehicle {Cooling module for vehicle}

The present invention relates to a cooling module for a vehicle, and more particularly, to a vehicle capable of efficiently using air introduced through an air inlet formed at the lower end of the front end of the vehicle while reducing the occupied space when installed at the front end of the vehicle. It relates to the cooling module of

BACKGROUND ART In general, in a vehicle, heating components are cooled using a cooling fluid such as cooling water, a refrigerant, or oil. Examples of heating components that require cooling in vehicles include engines and motors for driving vehicles, inverters, chargers, converters, batteries, fuel cell stacks, and other power electronic components and electric components for vehicles. In addition, in the air conditioning system of a vehicle, air (outdoor or indoor air) is cooled using a refrigerant and then supplied to the interior of the vehicle, so that the interior is cooled.

As described above, the cooling fluid such as coolant, refrigerant, oil, etc., which cools the heat-generating parts of the vehicle, and the refrigerant of the air conditioner used for air conditioning in the vehicle undergo heat dissipation and cooling processes in the heat exchanger. Here, the heat exchanger may be a heat exchanger constituting a typical vehicle cooling module, for example, a radiator (radiator), a condenser (condenser), or an oil cooler.

For example, the coolant that cools the engine or the motor undergoes a heat dissipation and cooling process in which heat is released through heat exchange with air in a radiator, which is a heat exchanger of a cooling module. In addition, the air conditioner refrigerant, which has absorbed heat from the air in the evaporator of the air conditioner system, undergoes a cooling and condensation process in which heat is released through heat exchange with outdoor air in the condenser of the cooling module. The oil used to cool the parts also goes through a heat dissipation and cooling process in which heat is released through heat exchange with the outside air in the oil cooler.

As described above, the radiator, the condenser, and the oil cooler are provided to dissipate the heat absorbed by the vehicle to the outside, and are heat exchangers constituting a cooling module of the vehicle together with a cooling fan.

In a typical vehicle, a cooling module is disposed at the front end of the vehicle body. In the cooling module, the cooling fan generates forced convection on the heat exchanger side to improve heat dissipation efficiency. The outside air is sucked in through a part (grill, etc.) so that the sucked outside air can pass through heat exchangers such as radiators, condensers, and oil coolers.

Recently, in a new vehicle design concept applied to electric vehicles, the height of the front hood is reduced as much as possible to improve aerodynamics, the air inlet, which is an opening at the upper part of the bumper (or the upper part of the bumper), is reduced or deleted, and the PE without the engine is reduced. (Power element) There is a tendency to place a frunk in the room.

Therefore, due to the lowered hood design and profile, interference may occur between the cooling module located at the front end of the vehicle and surrounding structures such as the hood, and the cooling module does not receive sufficient cooling air due to the deletion or reduction of the air inlet at the top of the bumper. is happening

In addition, in order to secure the trunk space, it is impossible to secure a layout in which air introduced through the air inlet of the upper part of the bumper (or the upper part of the bumper) passes through the cooling module and smoothly escapes to the rear. In order to cope with this, in some vehicles, the cooling module is tilted so as to avoid interference with the hood and perform a cooling function using only the air inlet at the lower part of the bumper (or lower part of the bumper).

1 is a front view showing an example of a vehicle in which an air inlet is formed at a lower portion of a bumper in a known vehicle, and FIG. 2 is a view illustrating a tilted state of a conventional cooling module.

Referring to the example of FIG. 1 , an air inlet 2 into which external air (outside air) for heat dissipation can be introduced is formed at the lower end of the front end of the vehicle, particularly at the lower end of the bumper 1. While the air passing through the air inlet 2 passes through the cooling module located at the front end of the vehicle, the heat exchanger of the cooling module performs heat exchange with the cooling fluid.

The existing cooling module arrangement method is a method in which the cooling module is placed vertically in the longitudinal direction of the vehicle, and in this method, the space occupied by the cooling module in the vehicle height direction at the front end of the vehicle is large and the space occupied in the longitudinal direction of the vehicle is small. .

This method is effective when the height of the hood 3 is high and the air inlet is secured at the upper end or upper side of the bumper 1, but in a new design trend, it is difficult to secure sufficient cooling performance and heat dissipation performance.

Accordingly, in order to reduce the space occupied by the cooling module in the vehicle height direction and to efficiently use the air inlet 2 located at the lower end of the bumper 1, as shown in FIG. 2, the cooling module 4 A rearward tilting arrangement method can be applied.

Referring to FIG. 2, it can be seen that a front trunk (frunk) 5, which is a space for loading objects, is disposed on the upper part of the front end of the vehicle, and an air inlet part 2 is formed at the lower part of the bumper 1. can In addition, it can be seen that the heat exchangers of the cooling module 4 are disposed in a tilted state on the air flow path having the air inlet 2 as an inlet.

3 is a view showing a comparison between a vertical arrangement structure and a tilt arrangement structure of a cooling module. When the existing vertically-arranged cooling module 4 is applied to the latest trend design, the height of the hood 3 cannot be sufficiently lowered due to limitations in reducing the occupied space in the vehicle height direction, resulting in a decrease in the aerodynamic improvement effect of the vehicle. .

In addition, when the existing vertically arranged cooling module 4 is applied, air entering through the air inlet 2 formed only at the lower part of the bumper 1 passes through the upper part of the heat exchanger of the cooling module 3 in terms of cooling performance. does not pass through sufficiently, and heat dissipation performance deteriorates (a phenomenon in which air volume is insufficient at the top of the heat exchanger), and eventually causes an increase in power consumption of the related air conditioner compressor or cooling fan, resulting in deterioration in fuel and electric power.

And, as illustrated in FIG. 3 , in the arrangement structure in which the heat exchanger of the cooling module 4 is tilted by a predetermined tilting angle α, the air introduced through the lower end of the front end of the vehicle moves through the heat exchanger of the cooling module 4. As it rises along the heat exchanger, the lack of air volume at the top of the heat exchanger is reduced compared to the vertical arrangement structure.

However, when the heat exchanger of the cooling module 4 is tilted backward, the space occupied by the cooling module in the vehicle height direction can be reduced, but the space occupied by the vehicle in the longitudinal direction is significantly increased (see 'L' in FIG. 3). ' increase).

In addition, although the layout of the engine room or the PE room may vary depending on the vehicle, there is a restriction that cannot be applied to various layouts due to the increase in occupied space in the longitudinal direction of the vehicle. Furthermore, a problem in which the specifications of the heat exchanger must be different may occur due to performance considerations according to the tilting angle applied to each vehicle.

Therefore, the present invention has been created to solve the above problems, and can efficiently use the air introduced through the air inlet formed at the lower end of the front end of the vehicle while reducing the occupied space in the state installed at the front end of the vehicle. Its purpose is to provide a cooling module for a vehicle.

In addition, the installation angle of the second heat exchanger coupled to the first heat exchanger via a connector may be adjusted or changed according to the position of the selected fastening hole for adjustment that is fastened to the fastening hole for adjustment of the second bracket in the first bracket. It can be configured so that

Accordingly, according to the cooling module of the vehicle according to the present invention, it is possible to reduce the space occupied by the cooling module including the heat exchanger at the front end of the vehicle by differentiating the installation angle for each heat exchanger.

In addition, according to the cooling module of the present invention, the aerodynamic performance of the vehicle can be improved as the hood height can be reduced and the hood line and profile are improved.

The rear air guide 19 prevents air vortex from being formed at the rear of the first heat exchanger 11 and rectifies the air flow. As a result, after passing through the first heat exchanger 11, the air that collides with the rear air guide 19 and is guided flows in a direction perpendicular to the blades 17b of the cooling fans 16a and 16c.

The rear air guide 19 blocks the air that has passed through the first heat exchanger 11 from flowing upward while blocking the flow to the rear of the second heat exchanger 12, and the upper second heat exchanger 12 ) The air that has passed through and the air that has passed through the first heat exchanger 11 on the lower side are divided so that they do not mix with each other.

In addition, when the cooling fan is a centrifugal fan 16b, as shown in FIG. 10 , a rear air guide 20 may be additionally installed at the lower end of the second heat exchanger 12 to extend backward with a downward slope. .

In this case, the rear air guide 19 of the first heat exchanger 11 and the rear air guide 20 of the second heat exchanger 12 extend from the corresponding heat exchanger toward the impeller 17c of the centrifugal fan 16b. , It may be installed at an inclined angle extending in the radial direction of the impeller (17c).

Referring to FIG. 10 , it can be seen that the impeller 17c of the centrifugal fan 16b is disposed at the rear of the first heat exchanger 11 . 10, the fan shroud 17a of the centrifugal fan 16b, which is a cooling fan, is coupled to the outer portions of the first heat exchanger 11 and the second heat exchanger 12, and the centrifugal fan 16b It can be seen that the fan shroud 17a of ) covers the entire rear area of the first heat exchanger 11 and the second heat exchanger 12.

In this way, the cooling module according to the embodiment of the present invention has been described in detail. According to the cooling module of the present invention described above, as the installation angle is differentiated for each heat exchanger, as can be seen in FIG. 11, the cooling module is installed at the front end of the vehicle. The occupied space in the height direction can be reduced compared to the prior art.

In particular, according to the cooling module of the present invention, the aerodynamic performance of the vehicle can be improved as the hood height can be reduced and the hood line and profile are improved. In addition, it is possible to utilize the space below the bumper back beam for the installation of the heat exchanger (first heat exchanger) located on the lower side, and more space can be secured at the front end of the vehicle, thereby improving the utilization of the engine room or PE room. This will have an increasing effect.

In addition, as the arrangement of the heat exchanger, the air guide, and the cooling fan is optimized, the cooling efficiency of the cooling module can be improved. That is, as the lower heat exchanger (first heat exchanger) is vertically arranged at the front end of the vehicle behind the lower part of the bumper or the air inlet at the lower side of the bumper, the cooling efficiency of the lower part can be improved.

In addition, as the upper heat exchanger (second heat exchanger) and the rear cooling fan (axial flow fan and dual fan) are arranged in parallel, the cooling efficiency of the upper part can be improved. In addition, since a centrifugal fan as a cooling fan is disposed behind the lower heat exchanger, air flow and fan load can be reduced.

In addition, the air flow can be improved by setting the arrangement angle of the front air guide in consideration of the air flow in front of the upper heat exchanger, and the rear air guide installed considering the arrangement angle of the cooling fan located at the rear and the lower heat exchanger. As a result, the generation of vortex at the rear of the heat exchanger can be suppressed.

In addition, as shown in FIG. 11 , air introduced through the lower air inlet can naturally flow upward without being abruptly bent, and air flow resistance can be reduced through the improvement of the air flow path. In addition, an insufficient air volume at the top of the heat exchanger as in the prior art can be prevented.

In addition, it is possible to combine various types of cooling fans according to vehicle-specific layout and performance targets. That is, an axial fan can be basically used as a cooling fan, and a centrifugal fan can be used when considering the package side, or a dual fan can be used when performance is oriented.

In addition, it is possible to adjust and change the angle between the heat exchangers (the tilting angle of the second heat exchanger) by using the angle-adjustable connector. As a result, it is possible to share the specifications of the heat exchanger in a plurality of vehicle models, and it becomes unnecessary to change the specifications of the heat exchanger due to the change of the tilting angle.
