This application claims priority under 35 U.S.C. § 119 to Korean Patent Application No. 10-2017-0067489, filed on May 31, 2017, and No. 10-2018-0052584, filed on May 8, 2018 in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference in its entirety.
The following disclosure relates to a cooling module for a vehicle, and more particularly, to a cooling module for a vehicle including a condenser, a first radiator through which coolant for an engine flow, a second radiator through which coolant for electrical components flows, a condenser for condensing a refrigerant flowing in an air conditioning system for a vehicle, and an intercooler, and capable of evenly distributing air resistance of the front surface of the first radiator to secure an overall balance of an air volume distribution.
In recent years, in a process of assembling an automobile, in order to simplify and automate the process and to improve productivity, there has been proposed a technology of assembling assemblies in which a plurality of components are assembled in an assembling line, that is, modulating the assembles. A representative example is a front end module in which a cooling module and a bumper including a head lamp and a bumper beam are assembled and modularized.
The front end module has a cooling module including a radiator, a condenser, and a fan shroud and mounted on a cooling module mounting portion of a carrier, a headlamp mounted on a headlamp mounting portion of the carrier, and a bumper beam mounted on a front surface of the carrier around the carrier disposed at the center thereof, so as to be modularized.
Typically, the cooling module for a vehicle is configured by modularizing the radiator, and the condenser, and the fan shroud for cooling the radiator and the condenser by exchanging heat with air, and a hybrid electronic vehicle or a fuel cell vehicle further includes a radiator for electrical components for cooling the electrical components in addition to the above-mentioned configuration. The hybrid electronic vehicle is an apparatus that is driven by a motor at a constant speed and at the time of initial driving, and is operated by an internal combustion engine in a battery discharge mode to improve fuel efficiency. Here, the electrical components including the motor generate heat during operation, and it is necessary to install a cooling device that suppresses a temperature rise of the components in order to maintain input and output characteristics of the components in the best condition.
In particular, in the hybrid electronic vehicle, in addition to the engine, the electrical components, which are electric and electronic components including a motor, an inverter, a battery stack, and the like, should be cooled. However, since a certain temperature difference is generated between the coolant that has been passed through the engine and the coolant that has been passed through the electrical component, the hybrid electronic vehicle does not have one cooling system.
Therefore, a cooling system for a vehicle separately includes a system for cooling an engine and a system for cooling electrical components, and separately includes a radiator for cooling the engine and a low temperature radiator for cooling the electrical components. In general, the low temperature radiator is separately manufactured and is assembled on an upper side or a lower side of the condenser.
As the technology related to those described above, Korean Patent Laid Open Publication No. 2011-0075195 (published on Jul. 06, 2011 entitled “Cooling Module”) has been disclosed.
As illustrated in
In general, a vehicle using a diesel engine uses a supercharger for supplying the compressed air into a cylinder of the engine to improve the output of the engine. However, since a temperature of the air rapidly compressed by the supercharger becomes very high, a volume of the air expands and oxygen density is decreased, resulting in a phenomenon that a charging efficiency of the air in the cylinder is lowered. Therefore, the intercooler cools the high temperature air compressed by the supercharger, such that a suction efficiency of the cylinder of the engine of the vehicle including the intercooler is increased, a combustion efficiency is improved to increase the fuel efficiency, and the discharging of exhaust gases harmful to an environment such as carbon dioxide, exhaust fumes, and the like is also significantly reduced.
However, in a case in which the intercooler is additionally mounted in the hybrid electronic vehicle, a layout structure other than the existing two-column layout is required. In particular, a layout structure capable of compacting the entire cooling module and securing an overall balance of an air volume distribution is required.
(Patent Document 1) Korean Patent Laid Open Publication No. 2011-0075195 (published on Jul. 06, 2011 entitled “Cooling Module”)
An embodiment of the present invention is directed to providing a cooling module for a vehicle capable of evenly distributing air resistance of the front surface of a first radiator to secure an overall balance of an air volume distribution by disposing a condenser, a second radiator, and the first radiator in a flow direction of the air or disposing the second radiator, the condenser, and the first radiator in this order, and disposing an intercooler on lower sides of the condenser and the second radiator.
In one general aspect, a cooling module for a vehicle includes a condenser C disposed in the front of the vehicle to condense a refrigerant flowing in an air conditioning system for a vehicle; a first radiator R disposed at the rear of the condenser C and having a first heat exchange medium flowing therein; a second radiator L disposed between the condenser C and the first radiator R and having a second heat exchange medium flowing therein; and an intercooler I disposed on lower sides of the condenser C and the second radiator L and disposed in the front of the first radiator R.
In another general aspect, a cooling module for a vehicle includes a second radiator L disposed in the front of the vehicle and having a second heat exchange medium flowing therein; a first radiator R disposed at the rear of the second radiator L and having a first heat exchange medium flowing therein; a condenser C disposed between the second radiator L and the first radiator R and condensing a refrigerant flowing in an air conditioning system for a vehicle; and an intercooler I disposed on lower sides of the second radiator L and the condenser C and disposed in the front of the first radiator R.

A height HR of the core portion of the first radiator R may be greater than a summation of a height HC of the core portion of the condenser C and a height HI of the core portion of the intercooler I, or a summation of a height HL of the core portion of the second radiator L and a height HI of a core portion of the intercooler I, and the core portion of the condenser C, the core portion of the second radiator L, and the core portion of the intercooler I may be disposed to all overlap with the core portion of the first radiator R.
The first radiator R may be provided with a mounting pin connected to a vehicle body.

A distance between the 2-1-th header tank 31 of the second radiator L having an inlet part 39 to which the second heat exchange medium is introduced and one end of the condenser C adjacent to the second radiator L in a width direction thereof may be greater than a distance between the 2-2-th header tank 34 positioned at an opposite side of the 2-1-th header tank 31 and the other end of the condenser C adjacent to the second radiator L in the width direction.
The other end of the condenser C in the width direction may be disposed on the same plane as the 2-2-th header tank 34.
A length LI of a core portion of the intercooler I may be smaller than a length LR of the core portion of the first radiator R.
The cooling module for a vehicle may further include a fan shroud disposed at the rear of the first radiator R.
Hereinafter, a cooling module for a vehicle according to the present invention as described above will be described in detail with reference to the accompanying drawings.
A cooling module 10 for a vehicle according to the present invention generally includes a condenser C, a first radiator R, a second radiator L, and an intercooler I, as illustrated in
In this case, the condenser header tanks 11 may also be a cross-flow type in which they are disposed to be in parallel to each other to be spaced apart from each other by a predetermined distance in a length direction, and may also be a down-flow type in which they are disposed to be in parallel to each other to be spaced apart from each other by a predetermined distance in a height direction.
The condenser C performs condensation by exchanging heat with air in a process in which a refrigerant introduced into any one of the pair of condenser header tanks 11 flows along the tube.
Next, the first radiator R is disposed at the rear of the condenser C in a flow direction of air, has a first heat exchange medium flowing therein, and includes a 1-1-th header tank 21 provided to one side thereof in a length direction, a 1-2-th header tank 24 provided to the other side thereof in the length direction, a plurality of second tubes 22 having both ends fixed to the 1-1-th header tank 21 and the 1-2-th header tank 24, and a second pin 23 interposed between the second tubes 22. In this case, similarly to the condenser C, the first radiator R may also be a cross-flow type in which the 1-1-th header tanks 21 are disposed to be in parallel to each other to be spaced apart from each other by a predetermined distance in the length direction, and may also be a down-flow type in which the 1-1-th header tanks 21 are disposed to be in parallel to each other to be spaced apart from each other by a predetermined distance in a height direction. In this case, the header tanks may be disposed to be spaced apart from each other in the height direction. The first radiator R may be a high temperature radiator for cooling coolant of an engine. In the first radiator R, the coolant for cooling the engine is introduced into any one of a pair of 1-1-th header tank 21 and 1-2-th header tank 24, and the coolant exchanges heat with air in a process in which the coolant passes through the second tubes 22, such that the cooling is performed.
Next, the second radiator L is disposed between the condenser C and the first radiator R in the flow direction of air, has a second heat exchange medium flowing therein, and includes a 2-1-th header tank 31 provided to one side thereof in a length direction, a 2-2-th header tank 34 provided to the other side thereof in the length direction, a plurality of third tubes 32 having both ends fixed to the 2-1-th header tank 31 and the 2-2-th header tank 34, and a third pin 33 interposed between the third tubes 32. The second radiator L may be a low temperature radiator for cooling electrical components.
The intercooler I is disposed on lower sides of the condenser C and the second radiator L, and includes a 3-1-th header tank 41 provided to one side thereof in a length direction, a 3-2-th header tank 44 provided to the other side thereof in the length direction, a plurality of fourth tubes 42 having both ends fixed to the 3-1-th header tank 41 and the 3-2-th header tank 44, and a fourth pin 43 interposed between the fourth tubes 42. The intercooler I may be formed to be greater than widths of the condenser C and the second radiator L to occupy both the lower regions of the condenser C and the second radiator L, and may also be disposed on only the lower region of any one of the condenser C or the second radiator L depending on an application model. The intercooler L may also be an air-cooled intercooler, or a water-cooled intercooler. In the case in which the intercooler L is the water-cooled intercooler, the intercooler I may have a form in which a heat exchanger of a pin tube type is included in the housing, may also be formed in a plate type, and a form thereof may be variously modified.
As described above, the cooling module including the condenser C, the first radiator R, the second radiator L, and the intercooler I has a three-column layout structure unlike the cooling module having the conventional two-column layout structure. That is, the condenser C, the second radiator L, and the first radiator R are disposed in three columns in the flow direction of air, and the intercooler I is disposed on the lower sides of the condenser C and the second radiator L and at the front of the first radiator R.
As another form, the second radiator L, the condenser C, and the first radiator R are disposed in three columns in the flow direction of air, and the intercooler I is disposed on the lower sides of the second radiator L and the condenser C and at the front of the first radiator R. In this case, a temperature of the first heat exchange medium introduced into the first radiator R may be higher than a temperature of a second heat exchange medium introduced into the second radiator L. As a result, the air introduced into the cooling module passes through the condenser C, passes through the second radiator L having a relatively low temperature, and then passes through the first radiator R having a relatively high temperature, such that a heat exchange may be efficiently performed.
In addition, since a width in the flow direction of air of the intercooler I is thicker than those of the condenser C and the second radiator L, the intercooler I is disposed at the front of the first radiator R and is disposed on the lower sides of the condenser C and the second radiator L similarly to the condenser C and the second radiator L, such that the air introduced into the cooling module is uniformly resisted in a vertical direction while passing through the cooling module. As a result, the air evenly passes through the overall cooling module, thereby making it possible to maximize thermal performance of the cooling module. If resistance of air at any one portion is large, the air is not introduced well into the portion and the thermal performance is thus reduced.
A detailed size and a coupled structure of the cooling module having such a three-column layout structure will be described in detail with reference to
First, a width length LL of a core portion (tubes and pins) of the second radiator L may be longer than a width length LC of a core portion of the condenser C and a width length LR of a core portion of the first radiator R. That is, the pair of condenser header tanks 11 of the condenser C, and the 1-1-th header tank 21 and the 1-2-th header tank 24 of the first radiator L may be positioned between the 2-1-th header tank 31 and the 2-2-th header tank 34 of the second radiator L. Thereby, the condenser C and the first radiator R may be disposed to be in closely contact with the second radiator L, thereby minimizing a gap of each heat exchange period and minimizing a width of the cooling module in the length direction of the vehicle.
In this case, a 1-1-th radiator supporting part 25 provided to the 1-1-th header tank 21 formed one side of the first radiator R in the length direction thereof, and a 1-2-th radiator supporting part 26 provided to the 1-2-th header tank 24 formed on the other side thereof are connected to the 2-1-th header tank 31 formed on one side of the second radiator L in the length direction thereof and the 2-2-th header tank 34 formed on the other side thereof, respectively, such that the first radiator R is supported by the second radiator L.
In this case, since the width length LL of the core portion of the second radiator L is longer than the width length LR of the core portion of the first radiator R, the 1-1-th radiator supporting part 25 and the 1-2-th radiator supporting part 26 may protrude outwardly from the center of the first radiator R. On the other hand, the 2-1-th radiator supporting part 35 and the 2-2-th radiator supporting part 36 protrude in a direction of the first radiator R so as not to increase the width length of the core portion of the second radiator L, and are connected to the 1-1-th radiator supporting part 25 and the 1-2-th radiator supporting part 26, respectively.
In addition, a 1-1-th condenser supporting part 15 provided to one side of the condenser C in the length direction thereof and a 1-2-th condenser supporting part 16 formed on the other side thereof are connected to a 2-1-th condenser supporting part 37 provided to the 2-1-th header tank 31 of the second radiator L and a 2-2-th condenser supporting part 38 provided to the 2-2-th header tank 34, respectively, such that the condenser C is supported by the second radiator L.
In this case, since the width length LL of the core portion of the second radiator L is longer than the width length LC of the core portion of the condenser C, the 1-1-th condenser supporting part 15 and the 1-2-th condenser supporting part 16 may protrude outwardly from the center of the condenser C. On the other hand, the 2-1-th condenser supporting part 37 and the 2-2-th condenser supporting part 38 protrude in a direction of the condenser C so as not to increase the width length LL of the core portion of the second radiator L, and are connected to the 1-1-th condenser supporting part 15 and the 1-2-th condenser supporting part 16, respectively.
An inlet part 39 and an outlet part through which the second heat exchange medium is introduced in the second radiator L may be provided to the 2-1-th header tank 31, and an inlet part and an outlet part through which the first heat exchange medium is introduced in the first radiator R may be provided to the 1-2-th header tank 24. That is, by disposing positions of the inlet part and the outlet part of the second heat exchange medium and positions of the inlet part and the outlet part of the first heat exchange medium to be in directions opposite to each other, when the condenser C of the first column and the first radiator R of the third column are connected to the second radiator L, a gap of each heat exchange period may be minimized and the width of the cooling module in the length direction of the vehicle may be minimized so that the condenser C and the first radiator R do not overlap or interfere with each other. In this case, if the positions of the inlet part and the outlet part of the first heat exchange medium are positioned in a direction opposite to each other, the inlet part and the outlet part of the second heat exchange medium may also be disposed so as not to overlap with the positions of the inlet part and the outlet part of the first heat exchange medium.
In addition, a 1-1-th intercooler supporting part 45 provided to a 3-1-th header tank 41 formed on one side of the intercooler I in a length direction thereof and a 1-2-th intercooler supporting part 46 provided to a 3-2-th header tank 44 formed on the other side thereof are connected to a 2-1-th intercooler supporting part 27 provided to the 1-1-th header tank 21 of the first radiator R and a 2-2-th intercooler supporting part 28 provided to the 1-2-th header tank 24, respectively, such that the intercooler I is supported by the first radiator R.
In this case, since a distance between the 3-1-th header tank 41 of the intercooler I and the outermost portion of the 3-2-th header tank 44 is greater than a distance between the 2-1-th header tank 31 of the second radiator L and the outermost portion of the 2-2-th header tank 34, the 2-1-th intercooler supporting part 27 and the 2-2-th intercooler supporting part 28 may protrude outwardly from the center of the first radiator R. On the other hand, the 1-1-th intercooler supporting part 45 and the 1-2-th intercooler supporting part 46 protrude in a direction of the first radiator R so as not to increase a width length LI of the intercooler I, and are connected to the 2-1-th intercooler supporting part 25 and the 2-2-th intercooler supporting part 28, respectively.
Meanwhile, a height HR of the core portion of the first radiator R may be greater than a summation of a height HC of the core portion of the condenser C and a height HI of the core portion of the intercooler I, or a summation of a height HL of the core portion of the second radiator L and a height HI of the core portion of the intercooler I.
In addition, the core portion of the condenser C, the core portion of the second radiator L, and the core portion of the intercooler I may be disposed to all overlap with the core portion of the first radiator R.
In the above-mentioned configuration, since the height of the first radiator R is configured to be the largest height, and both the core portion of the condenser C and the core portion of the second radiator L are included in an area of the core portion of the first radiator R, the first radiator R forms the outermost portion of the cooling module when being viewed in the height direction. In this case, the first radiator R is provided with a mounting pin such that the cooling module may be easily connected to a vehicle body.
Meanwhile, an effective area of the core portion of the condenser C may be smaller than an effective area of the core portion of the second radiator L. In addition, a summation of an effective area of the core portion of the condenser C and an effective area of the core portion of the intercooler I may be smaller than a summation of an effective area of the core part of the first radiator R. Thereby, a fan of a fan shroud disposed at the rear of the first radiator R may cover the overall heat exchanger.
Meanwhile, a distance between the 2-1-th header tank 31 of the second radiator L having the inlet part 39 to which the second heat exchange medium is introduced and one end of the condenser C adjacent to the second radiator L in the length direction thereof may be greater than a distance between the 2-2-th header tank 34 positioned at an opposite side of the 2-1-th header tank 31 and the other end of the condenser C adjacent to the second radiator L in the length direction. That is, when the cooling module is viewed in the direction in which the air is introduced, the condenser C is disposed to be biased to one side with respect to the second radiator L, and in particular, the condenser C is disposed to be as far away as possible from the inlet part 39 into which the second heat exchange medium is introduced. Thereby, since the condenser C is not present in the front of the vicinity of the inlet part 39 of the second radiator L, the air introduced into the front of the vicinity of the inlet part 39 does not pass through the condenser C and is in an un-heated state, thereby making it possible to efficiently cool the second heat exchange medium introduced in the second radiator L.
In this case, the other end of the condenser C in the length direction may be disposed on the same plane as the 2-2-th header tank 34. That is, the condenser C is disposed to be maximally biased to the other end of the second radiator L in the length direction, such that an area in the vicinity of the inlet part 39 into which the second heat exchange medium is introduced in the second radiator L may be maximally increased, the second heat exchange medium may be maximally and efficiently cooled, and thermal performance of both the condenser C and the second radiator L may be improved.
In this case, a liquid-vapor separator may be provided between one end of the condenser C and the 2-1-th header tank 31 of the second radiator L.
The distance between the 3-1-th header tank 41 of the intercooler I and the outermost portion of the 3-2-th header tank 44 is greater than the distance between the 2-1-th header tank 31 of the second radiator L and the outermost portion of the 2-2-th header tank 34, and a length LI of the core portion of the intercooler I may be smaller than a length LR of the core portion of the first radiator R.
Thereby, since the portions that the 3-1-th header tank 41 and the 3-2-th header tank 44 of the intercooler I are connected to the core portions are positioned between the 1-1-th header tank 21 and the 1-2-th header tank 24 of the first radiator R, the intercooler I and the first radiator R may be disposed to be in closely contact with each other, thereby making it possible to minimize the gap of each heat exchange period and to minimize the width of the cooling module in the length direction of the vehicle.
According to another exemplary embodiment of the present invention, as illustrated in
As described above, the cooling module for a vehicle according to the present invention includes the condenser C, the first radiator R, the second radiator L, and the intercooler I, and is formed by disposing the condenser C, the second radiator L, and the first radiator R in the flow direction of the air and disposing the intercooler I on the lower sides of the condenser C and the second radiator L, thereby making it possible to compact the cooling module and to evenly distribute the air resistance of the front surface of the first radiator R to secure the overall balance of the air volume distribution.
Further, the width length LL of the core portion of the second radiator L is formed to be longer than the width length LC of the core portion of the condenser C and the width length LC of the core portion of the first radiator R, such that the condenser C and the first radiator R are disposed to be in closely contact with the second radiator L, thereby making it possible to minimize a gap of each heat exchange period and to minimize a width of the cooling module in the length direction of the vehicle.
The present invention is not limited to the above-mentioned exemplary embodiments but may be variously applied, and may be variously modified by those skilled in the art to which the present invention pertains without departing from the gist of the present invention claimed in the claims.
