first condenser 130, as shown inFIG. 4 andFIG. 5 , includes acondensing portion 131, acoolant inlet 135, and acoolant outlet 137, and these will be respectively described. - Firstly, the
condensing portion 131 is formed by twoplates 133 that are combined to form acoolant passage 132 through which refrigerant flows, a plurality of thecoolant passages 132 that are made by the plates are arranged with a predetermined distance from each other. - Here, the
condensing portion 131 can have 7 sets ofrefrigerant passages 132 those are formed by combining twoplates 133, wherein 7 sets of refrigerant passages can be laminated. - The
refrigerant inlet 135 is formed at one end of the condensingportion 131 to be connected to therefrigerant passage 132 and protrudes out of theheader tank 121 that is disposed at a lower portion of the radiator for anelectric device 120 to be connected to a not-illustrated refrigerant pipe. - And, the
refrigerant outlet 137 corresponding to therefrigerant inlet 135 is formed at the other side of the condensingportion 131 to be connected to therefrigerant passage 132 and protrudes out of theheader tank 121 at an opposite side of therefrigerant inlet 135. - Here, one
plate 133 that is disposed at one side of twoplates 133 has a plurality ofprotrusions 138 that are formed at one side with a predetermined distance and theother plate 133 that is disposed at the other side contacts oneplate 133 through eachprotrusion 138. - That is, the
protrusion 138 is formed on an upper surface of theplate 133 that is disposed on an upper side based on the drawing in various embodiments, and theupper side plate 133 is combined with thelower side plate 133 through theprotrusion 138 in such a way that twoplates 133 are securely combined with each other. - Also, when the coolant that flows in the
header tank 121 flows spaces that is formed by eachprotrusion 138, the flowing path of the coolant is continuously changed by theprotrusion 138 such that the heat exchange between the coolant and the refrigerant is efficiently performed and the condensing rate of the refrigerant is enhanced. - Meanwhile, a radiating
protrusion 139 is integrally formed at theplate 133 that is disposed at the other side of twoplates 133, and the radiatingprotrusion 139 is formed toward an outside at both sides in a width direction of the condensingportion 131 in various embodiments. One will appreciate that such integral components may be monolithically formed. - The radiating
protrusion 139 makes the heat of refrigerant passing therefrigerant passage 132 of thefirst condenser 130 be efficiently exchanged with coolant inside theheader tank 121. - That is, the
first condenser 130 having the above configuration enables coolant to flow a gap between twoplates 133 and theprotrusion 138 generates flowing resistance to increase contact area with theplate 133 such that refrigerant passing therefrigerant passage 132 efficiently exchanges heat with coolant and condensing efficiency of refrigerant is enhanced. - Also, the radiating
protrusion 139 transmits the heat that is transmitted from the refrigerant passing therefrigerant passage 132 to the coolant flowing inside theheader tank 121. - And, the
second condenser 140 is disposed at the other side based on a width direction of a vehicle at a front side of the radiator for astack 110, is connected to thefirst condenser 130 through a refrigerant piping, and condenses refrigerant that is condensed by thefirst condenser 130 as a second condensing process. - Here, the
second condenser 140 is disposed at a front side of the radiator for a stack to be an air cooled type that cools refrigerant by exchanging heat with outside air. - The
second condenser 140 has a plurality of coolant tubes 31 that are disposed with an equal distance from each other in a height direction and can be a fin-tube type having a heat radiating fin (P) between thecoolant tubes 141. - A
receiver dryer 143 is integrally formed on thesecond condenser 140 at one side that faces the radiator forelectric devices 120 to separate gaseous refrigerant from the refrigerant that is condensed. One will appreciate that such integral components may be monolithically formed. - Meanwhile, in various embodiments of the present invention, the radiator for
electric devices 120 and thesecond condenser 140 are mounted on the radiator for astack 110 through a mountingbracket 150, and the radiator forelectric devices 120 is arranged in a row with thesecond condenser 140 based on a vehicle width direction. - Here, at least one mounting
protrusion 113 is integrally formed on an exterior circumference of the radiator for astack 110 along a length direction of theheader tank 111 of the radiator for astack 110 corresponding to the mountingbracket 150. One will appreciate that such integral components may be monolithically formed. - That is, the radiator for
electric devices 120 and thesecond condenser 140 is mounted on the mountingprotrusion 113 that is formed on theheader tank 111 through the mountingbracket 150 at a front side of the radiator for astack 110, and therefore they are integrally mounted on the radiator for astack 110. - In the cooling module for a
vehicle 100, the radiator forelectric devices 120 is disposed at a front side of one side based on a vehicle width direction according to a amount of heat transfer and a driving temperature, and therefore the cooling performance is not deteriorated without size increment. - Simultaneously, the
cooling module 100 prevents the deterioration of the cooling performance through the first and thesecond condensers - Also, the radiator for
electric devices 120 and thesecond condenser 140 are disposed on an equal line at a front side of the radiator for astack 110 such that overall thickness of thecooling module 100 is short and font side collision performance of a vehicle is improved. - Accordingly, in a
cooling module 100 for a vehicle according to various embodiments of the present invention, a condenser is divided into a water cooled type of afirst condenser 130 and an air cooled type of asecond condenser 140, each condenser (130 and 140), a radiator forelectric devices 120, and a radiator for astack 120 are disposed according to a amount of heat transfer and a driving temperature as one package in an air conditioning system, and therefore there are effects that cooling performance of a vehicle and cooling/heating performance are improved, cooling performance difference is prevented, consuming power of a water pump and a cooling fan are saved, travel distance is increased, and capacity of cooling fan and each radiator are reduced to save manufacturing cost. - Also, an air conditioning system and a cooling system are unified to form one module, and therefore a package is reduced, capacity of each radiator can be reduced, and manufacturing cost is saved.
- Also, when it is disposed at a front side of an engine compartment, a mounting space is minimized, and therefore there is an effect that space efficiency is improved in a vehicle.
- Also, a layout of piping is simple, and therefore there are effects that piping length through which refrigerant and coolant flow is reduced, flowing resistance of each operating fluid is reduced, and flowing amount is increased.
