Description

TECHNICAL AREA

[0001] The invention relates to a cooling module for a vehicle according to the preamble of the independent patent claims. BACKGROUND

[0002] In recent years, a technology for assembling subassemblies—that is, modularizing subassemblies—has been proposed in the automotive assembly process. This technology involves assembling multiple components on a single assembly line to simplify and automate the process and improve productivity. A representative example is a front-end module, in which a cooling module and a bumper, including a headlight and bumper support, are assembled and modularized.

[0003] The front part module includes a cooling module containing a radiator, condenser and fan shroud, which is attached to a cooling module mounting section of a carrier, a headlight mounted to a headlight mounting section of the carrier, and a bumper carrier mounted to a front surface of the carrier around the carrier located in the middle of it, so that it is modularized.

[0004] Typically, a vehicle's cooling module is configured by modularizing the radiator, condenser, and fan shroud to cool the radiator and condenser by exchanging heat with air. In addition to the configuration mentioned above, a hybrid electric vehicle or fuel cell vehicle also includes a cooler for electrical components to cool the electrical components. A hybrid electric vehicle is a device that is driven by a motor at constant speed and during acceleration, and that uses an internal combustion engine in a battery-discharge mode to improve fuel efficiency.The electrical components include the motor, which generates heat during operation, making it necessary to install a cooling device to prevent a temperature increase of the components in order to maintain the input and output characteristics of the components in optimal condition.

[0005] In particular, in the hybrid electric vehicle, in addition to the power unit, the electrical components—which include the motor, inverter, battery pack, and the like—should be cooled. However, the hybrid electric vehicle does not have a cooling system because a certain temperature difference is created between the refrigerant that has passed through the power unit and the refrigerant that has passed through the electrical components.

[0006] Thus, a vehicle's cooling system comprises separate systems for cooling the engine and electrical components, and includes separate radiators for cooling the engine and low-temperature radiators for cooling the electrical components. Generally, the low-temperature radiator is manufactured separately and mounted on either the top or bottom of the condenser.

[0007] The technology relating to the above has been disclosed in the Korean patent publication KR 10 2011 0 075 195 A (published on July 6, 2011, entitled “Cooling Module”).

[0008] As in Fig. As shown in Figure 1, the cooling module, when considered with the exception of the fan shroud S, is formed in a layered structure of two columns. A low-temperature cooler L is arranged at the lower end of a condenser C to form a first column, and a cooler R is arranged at the rear end of the first column, comprising the condenser C and the low-temperature cooler L, to form a second column. Furthermore, the hybrid electronics module may be fitted with an intercooler. The intercooler is a device for cooling air that is compressed to high temperature and pressure by a supercharger to increase the output of the engine.

[0009] Generally, a vehicle with a diesel engine uses a supercharger to supply compressed air to the engine's cylinders, thereby increasing engine output. However, as the air expands, its oxygen density decreases, resulting in reduced air-to-cylinder efficiency. This is because the rapidly compressed air becomes very hot. An intercooler cools the high-temperature air being compressed by the supercharger, thus improving the intake efficiency of the cylinders in the vehicle's engine housing the intercooler. This enhances combustion efficiency, thereby increasing fuel efficiency, and significantly reduces emissions of harmful exhaust gases such as carbon dioxide and other pollutants.

[0010] However, a different layered structure than the existing two-column arrangement is required if the intercooler is additionally installed in the hybrid electric vehicle. In particular, an arrangement structure is needed that can compact the entire cooling module and ensure an overall balance of the air volume distribution.

[0030] In the following, a cooling module for a vehicle in accordance with the present invention as described above will be described in detail with reference to the accompanying drawings.

[0031] As in Fig. As shown in Figure 2, a cooling module 10 for a vehicle, in accordance with the present invention, generally comprises a condenser C, a first radiator R, a second radiator L, and an intercooler I. The condenser C is a heat exchanger located at the front of a vehicle to condense a refrigerant flowing in a vehicle air conditioning system. It includes a pair of condenser head tanks 11, several first tubes 12, both ends of which are attached to the condenser head tanks 11, and a first pin 13 inserted between the first tubes 12. The cooling module also includes a liquid-vapor separator located on one side of the condenser C.

[0032] In this case, the condenser head containers 11 can also be of a cross-flow type, in which they are spaced parallel to each other in such a way that they are spaced apart from each other by a predetermined distance in a longitudinal direction, and they can also be of a downward flow type, in which they are arranged parallel to each other in such a way that they are spaced apart from each other by a predetermined distance in a vertical direction.

[0033] In a process in which a refrigerant introduced into one of the pair of condenser head containers 11 flows along the pipe, the condenser C carries out condensation by exchanging heat with air.

[0034] The first cooler R is arranged in a flow direction of the air on a rear side of the condenser C, it has a first heat exchange medium flowing therein, and it includes a first head tank 21, which is provided on one side of it in a longitudinal direction, a second head tank 24, which is provided on the other side of it in a longitudinal direction, several second tubes 22, both ends of which are attached to the first head tank 21 and to the second head tank 24, and a second pin 23, which is inserted between the second tubes 22.Similar to the condenser C, the first cooler R can also be of a cross-flow type, in which the first head tanks 21 are arranged parallel to each other and spaced apart by a predetermined distance in the longitudinal direction, or it can also be of a downward-flow type, in which the first head tanks 21 are arranged parallel to each other and spaced apart by a predetermined distance in a vertical direction. In this case, the head tanks can be spaced apart vertically. The first cooler R can be a high-temperature cooler for cooling refrigerants of a power engine.In the first cooler R, the refrigerant for cooling the engine is introduced into a pair of the first head tank 21 and the second head tank 24, and exchanges heat with air in a process in which the refrigerant passes through the second tubes 22, so that the cooling is carried out.

[0035] The second cooler L is arranged in the direction of airflow between the condenser C and the first cooler R. It contains a second heat exchange medium flowing within it and includes a first head tank 31, which is provided longitudinally on one side; a second head tank 34, which is provided longitudinally on the other side; several third tubes 32, both ends of which are attached to the first head tank 31 and the second head tank 34, respectively; and a third pin 33, which is inserted between the third tubes 32. The second cooler L can be a low-temperature cooler for cooling electrical components.

[0036] The intercooler I is arranged on the undersides of the condenser C and the second cooler L and comprises a first head chamber 41, which is provided longitudinally on one side of the condenser C, a second head chamber 44, which is provided longitudinally on the other side of the second head chamber, several fourth tubes 42, both ends of which are attached to the first head chamber 41 and the second head chamber 44, and a fourth pin 43, which is inserted between the fourth tubes 42. The intercooler I can be larger than the widths of the condenser C and the second cooler L in order to occupy the two lower regions of both the condenser C and the second cooler L, and depending on the application model, it can also be arranged only on the lower region of either the condenser C or the second cooler L. Furthermore, the intercooler L can be an air-cooled intercooler or a water-cooled intercooler.If the intercooler L is a water-cooled intercooler, the intercooler I can have a form in which a pin tube type heat exchanger is included in the housing, it can also be formed in a plate type, and one of its forms can be modified in various ways.

[0037] As described above, the cooling module, which contains the condenser C, the first radiator R, the second radiator L, and the intercooler I, has a three-column arrangement structure, unlike the cooling module with the conventional two-column configuration. That is, the condenser C, the second radiator L, and the first radiator R are arranged in three columns in the direction of airflow, and the intercooler I is located on the undersides of the condenser C and the second radiator L and on the front of the first radiator R.

[0038] In another configuration, the second cooler L, the condenser C, and the first cooler R are arranged in three columns in the direction of airflow, with the intercooler I positioned on the undersides of the second cooler L and the condenser C, and on the front of the first cooler R. In this configuration, the temperature of the first heat exchange medium entering the first cooler R can be higher than the temperature of a second heat exchange medium entering the second cooler L. As a result, the air entering the cooling module through the condenser C passes through the second cooler L at a relatively low temperature and then through the first cooler R at a relatively high temperature, thus enabling efficient heat exchange.

[0039] Since the width in the airflow direction of the intercooler I is greater than that of the condenser C and the second cooler L, the intercooler I is also located at the front of the first cooler R and, similarly to the condenser C and the second cooler L, on the undersides of the condenser C and the second cooler L. This ensures that the air introduced into the cooling module encounters a uniform resistance in a vertical direction as it passes through the cooling module. As a result, the air flows evenly through the entire cooling module, thus maximizing its cooling capacity. If the air resistance is high in any section, the air is not introduced efficiently into that section, and the cooling capacity is therefore reduced.

[0040] Based on Fig. Sections 2 to 5 describe the exact size and coupled structure of the cooling module with a three-column arrangement structure.

[0041] Initially, a width dimension LL of a core section (tubes and pins) of the second cooler L can be larger than a width dimension LC of a core section of the condenser C and a width dimension LR of a core section of the first cooler R. This means that the pair of condenser head tanks 11 of condenser C and the first head tank 21 and second head tank 24 of the first cooler L can be positioned between the first head tank 31 and the second head tank 34 of the second cooler L. This allows the condenser C and the first cooler R to be in close contact with the second cooler L, minimizing any gap during each heat exchange cycle and minimizing the width of the cooling module in the longitudinal direction of the vehicle.

[0042] In this case, a first radiator support element 25, provided on the first head reservoir 21, which is formed on one side of the first radiator R in its longitudinal direction, and a second radiator support element 26, provided on the second head reservoir 24, which is formed on the other side of it, are connected to the first head reservoir 31, which is formed on one side of the second radiator L in its longitudinal direction, and to the second head reservoir 34, which is formed on the other side of it, respectively, so that the first radiator R is supported by the second radiator L.

[0043] In this case, the first radiator support part 25 and the second radiator support part 26 can project outwards from the center of the first radiator R, since the width dimension LL of the core section of the second radiator L is larger than the width dimension LR of the core section of the first radiator R. On the other hand, the first radiator support part 35 and the second radiator support part 36 project outwards from the first radiator R in such a way that they do not increase the width dimension of the core section of the second radiator L, and they are connected to the first radiator support part 25 and the second radiator support part 26, respectively.

[0044] Furthermore, a first condenser support part 15, which is provided on one side of the condenser C in the longitudinal direction thereof, and a second cooler support part 16, which is formed on the other side thereof, are connected to a first condenser support part 37, which is provided on the first head container 31 of the second cooler L, and to a second condenser support part 38, which is provided on the second head container 34, respectively, so that the condenser C is supported by the second cooler L.

[0045] In this case, the first capacitor support part 15 and the second capacitor support part 16 can project outwards from the center of the capacitor C, since the width dimension LL of the core section of the second cooler L is larger than the width dimension LC of the core section of the capacitor C. On the other hand, the first capacitor support part 37 and the second capacitor support part 38 project outwards from the capacitor C in such a way that they do not increase the width dimension LL of the core section of the second cooler L, and they are connected to the first capacitor support part 15 and to the second capacitor support part 16, respectively.

[0046] The first head tank 31 can be provided with an inlet section 39 and an outlet section through which the second heat exchange medium is introduced into the second cooler L, and the second head tank 24 can be provided with an inlet section and an outlet section through which the first heat exchange medium is introduced into the first cooler R. That is, by arranging the positions of the inlet and outlet sections of the second heat exchange medium and the positions of the inlet and outlet sections of the first heat exchange medium in opposite directions, the gap between each heat exchange cycle can be minimized, and the width of the cooling module in the longitudinal direction of the vehicle can be minimized so that the condenser C and the first cooler R do not overlap or interfere with each other when the condenser C of the first column and the first cooler R of the third column are connected to the second cooler L.In this case, the inlet and outlet parts of the second heat exchange medium can be arranged in such a way that they do not overlap with the positions of the inlet and outlet parts of the first heat exchange medium if the positions of the inlet and outlet parts of the first heat exchange medium are positioned in directions that are opposite to each other.

[0047] Furthermore, a first intercooler support element 45, which is provided on a first head tank 41 formed on one side of the intercooler I in a longitudinal direction thereof, and a second intercooler support element 46, which is provided on a second head tank 44 formed on the other side thereof, are connected to a first intercooler support element 27 provided on the first head tank 21 of the first cooler R, respectively, and to a second intercooler support element 28 provided on the second head tank 24, so that the intercooler I is supported by the first cooler R.

[0048] Since in this case the distance between the first head chamber 41 of the intercooler I and the outermost section of the second head chamber 44 is greater than the distance between the first head chamber 31 of the second cooler L and the outermost section of the second head chamber 34, the first intercooler support part 27 and the second intercooler support part 28 can project outwards from the center of the first cooler R. On the other hand, the first intercooler support part 45 and the second intercooler support part 46 project forward in one direction of the first cooler R so as not to increase a width dimension LI of the intercooler I, and they are connected to the first intercooler support part 25 and to the second intercooler support part 28, respectively.

[0049] Meanwhile, the height HR of the core section of the first cooler R can be greater than the sum of the height HC of the core section of the condenser C and the height HI of the core section of the intercooler I, or greater than the sum of the height HL of the core section of the second cooler L and the height HI of the core section of the intercooler I.

[0050] Furthermore, the core section of the condenser C, the core section of the second cooler L and the core section of the intercooler I can be arranged in such a way that they overlap with the core section of the first cooler R.

[0051] Since, in the configuration mentioned above, the height of the first cooler R is configured as the greatest height, and both the core section of the condenser C and the core section of the second cooler L are contained within a region of the core section of the first cooler R, the first cooler R forms the outermost section of the cooling module in the vertical direction. In this case, the first cooler R is equipped with a mounting pin so that the cooling module can be easily connected to a vehicle body.

[0052] Meanwhile, the effective area of ​​the core section of condenser C can be smaller than the effective area of ​​the core section of the second cooler L. Furthermore, the sum of the effective areas of the core section of condenser C and the effective areas of the core section of intercooler I can be smaller than the effective area of ​​the core section of the first cooler R. This allows a fan or fan shroud located on the rear of the first cooler R to cover the entire heat exchanger.

[0053] Meanwhile, the distance between the first head chamber 31 of the second cooler L, with the inlet section 39 into which the second heat exchange medium is introduced, and one end of the condenser C adjacent to the second cooler L in its longitudinal direction, can be greater than the distance between the second head chamber 34, positioned on the opposite side of the first head chamber 31, and the other end of the condenser C adjacent to the second cooler L in its longitudinal direction. That is, when the cooling module is considered in the direction in which the air is introduced, the condenser C is arranged asymmetrically to one side with respect to the second cooler L, and in particular, the condenser C is arranged as far as possible from the inlet section 39 into which the second heat exchange medium is introduced.Since the condenser C is not present in the front area of ​​the inlet part 39 of the second cooler L, the air introduced into the front area of ​​the inlet part 39 does not pass through the condenser C and is in an unheated state, which allows the second heat exchange medium introduced into the second cooler L to be effectively cooled.

[0054] In this case, the other end of the condenser C can be arranged longitudinally in the same plane as the second head tank 34. That is, the condenser C is arranged such that it is maximally asymmetrical longitudinally with respect to the other end of the second cooler L, so that the area near the inlet 39, into which the second heat exchange medium is introduced into the second cooler L, can be maximally increased, the second heat exchange medium can be cooled maximally and effectively, and the cooling capacity of both the condenser C and the second cooler L can be improved.

[0055] In this case, a liquid-vapor separator can be provided between one end of the condenser C and the first head tank 31 of the second cooler L.

[0056] The distance between the first head chamber 41 of the intercooler I and the outermost section of the second head chamber 44 is greater than the distance between the first head chamber 31 of the second cooler L and the outermost section of the second head chamber 34, and a length LI of the core section of the intercooler I can be less than a length LR of the core section of the first cooler R.

[0057] Since the sections in which the first head tank 41 and the second head tank 44 of the intercooler I are connected to the core section are positioned between the first head tank 21 and the second head tank 24 of the first cooler R, the intercooler I and the first cooler R can be arranged in close contact with each other, which makes it possible to minimize the gap of each heat exchange period and to minimize the width of the cooling module in the longitudinal direction of the vehicle.

[0058] As in Fig.As shown in Figure 5, in accordance with another exemplary embodiment of the present invention, the three-column arrangement structure, which can distribute the air resistance of the front surface of the first cooler evenly in order to ensure an overall balance of the air volume distribution, can itself be implemented with a structure in which the second cooler L with the second heat exchange medium flowing therein; the condenser C, to condense the refrigerant flowing in the air conditioning system for a vehicle; and the first cooler R with the first heat exchange medium flowing therein are arranged in this order in the direction of airflow from the front of the vehicle, and in which the intercooler I is arranged on the undersides of the second cooler L and the condenser C and in the front of the first cooler R.

[0059] As described above, the cooling module for a vehicle in accordance with the present invention comprises the condenser C, the first radiator R and the second radiator L and the intercooler I and is formed in such a way that the condenser C, the second radiator L and the first radiator R are arranged in the direction of airflow and that the intercooler I is arranged on the undersides of the condenser C and the second radiator L, which makes it possible to compact the cooling module and to distribute the air resistance of the front surface of the first radiator R evenly in order to ensure the overall balance of the air volume distribution.

[0060] Furthermore, the width dimension LL of the core section of the second cooler L is longer than the width dimension LC of the core section of the condenser C and the width dimension LC of the core section of the first cooler R, so that the condenser C and the first cooler R are arranged in close contact with the second cooler L, which makes it possible to minimize a gap of each heat exchange period and to minimize a width of the cooling module in the longitudinal direction of the vehicle.
