FIG. 4 , eachbarrier 128 is alternatively disposed at an upper side and a lower side of eachrefrigerant flow tube 127 in a crossing manner, and the coolant that is cooled by flowing in eachtube 116 flows into thesecond header tank 114 to be exhausted through theoutlet 113 of thesecond header tank 114, and while the coolant is flowing in thesecond header tank 114, it flows upward and downward repeatedly. - Accordingly, when the refrigerant passes each
refrigerant flow tube 127 of thefirst condenser 120, the contact area is increased to improve the condensing efficiency. - Heat radiating fins (P) that are disposed between the
refrigerant flow tubes 127 effectively radiate the heat that is transferred from the refrigerant flowing therein to the coolant flowing in thesecond header tank 114. - Meanwhile, it is described that the
first condenser 120 is disposed in thesecond header tank 114 that is disposed at a lower portion of thefirst header tank 112 in various embodiments, but it is not limited thereto, and in a case in which a crossflow type in which theheader tanks radiator 110 is applied to this invention, one of condensers can be disposed in a header that receives cooled coolant. - Also, the
barrier 128 is disposed at an upper side and a lower side of therefrigerant flow tube 127 in a crossing manner as described in the drawings in various embodiments, but it is not limited thereto, and the position of thebarrier 128 can be changed according to the disposition direction of therefrigerant flow tube 127 and the flow direction of the coolant. - Further, the
second condenser 130 is connected to thefirst condenser 120 through therefrigerant pipe 121, condensed refrigerant flows into thefirst condenser 120 that is disposed at a front side of theradiator 110, and the refrigerant is further condensed by thefirst condenser 120 through heat exchange with ambient air. - Here, the
second condenser 130 can be a fin-tube type as a heat exchanger, and can be disposed in a length direction at an upper side of a front side of theradiator 110. - Meanwhile, a receiver drier 140 can be disposed on the
radiator 110 in various embodiments, and the receiver drier 140 is disposed on therefrigerant pipe 121 that connects thefirst condenser 120 with thesecond condenser 130 at one side in a width direction of a vehicle to separate gaseous refrigerant from condensed refrigerant that is exhausted from thefirst condenser 120. - Here, the
first condenser 120 is connected to thesecond condenser 130 in series through the receiver drier 140. - Accordingly, the condensed refrigerant that is exhausted from the
first condenser 120 and passes the receiver drier 140 flows into thesecond condenser 130, and thesecond condenser 130 further condenses the refrigerant through heat exchange with ambient air. - In various embodiments, it is described that the receiver drier 140 is disposed at one side of the radiator in a width direction of a vehicle, but it is not limited thereto, and the receiver drier 140 can be integrally disposed at one side of the
second condenser 130. - That is, the
first condenser 120 is a coolant cooling type in which refrigerant is cooled by water as coolant in various embodiments, and thesecond condenser 130 is an air cooling type in which refrigerant is cooled by ambient air. - Accordingly, the
first condenser 120 that is a water cooling type uses coolant of which a heat transfer coefficient is larger than that of ambient air to cool refrigerant, and therefore condensing pressure can be reduced therein. - Also, the
second condenser 130 that is an air cooling type receives liquid state refrigerant that is condensed by thefirst condenser 120 through the receiver drier 140 to cool the liquefied refrigerant, and therefore the temperature difference between ambient air and the refrigerant is increased to be able to realize subcooling and the heat transfer amount of therefrigerant pipe 121 is reduced. - As described above, a
cooling module 100 for a vehicle according to various embodiments of the present invention efficiently uses advantageous points such as a condensing pressure reduction that is a merit of the coolant cooling type and the subcooling that is a merit of the air cooling type, wherein the first andsecond condensers radiator 110 and in thesecond header tank 114 such that overall size is reduced and space usability is improved in a narrow engine compartment. - Meanwhile, in a description of a cooling module for a
vehicle 100 according to various embodiments of the present invention, it is described that thesecond condenser 130 is connected to thefirst condenser 120 through the receiver drier 140 as various embodiments, but it is not limited thereto. - That is, the layout of the
refrigerant pipe 121 is changed such that thesecond condenser 130 directly receives mixed refrigerant of liquid and gas from thefirst condenser 120 to condense the refrigerant, the condensed refrigerant is supplied to the receiver drier 140, and thesecond condenser 130 receives the refrigerant from thereceiver driver 140 again to further condense the liquid refrigerant that is separated by the receiver drier 140. - Also, the interior room of the
second condenser 130 can be divided into at least two portions such that the refrigerant is sequentially condensed depending on the condition of refrigerant to improve the condensing efficiency. - Accordingly, a
cooling module 100 for a vehicle according to various embodiments of the present invention applies a coolant cooling type and an air cooling type to condense refrigerant, and therefore condensing pressure is reduced, condensing performance of refrigerant is improved to improve cooling performance, and simultaneously package performance is improved by incorporating them in aradiator 110. - Also, because the condensing pressure of the refrigerant is reduced and the condensing performance is improved, power consumption of a compressor is reduced and fuel consumption efficiency is improved.
- In addition, because a
first condenser 120 that exchanges heat with coolant is disposed in aheader tank 114 that is disposed at a lower portion of aradiator 110, cooled coolant efficiently exchanges heat with refrigerant, the layout of a narrow engine compartment becomes simple, space utilization is improved, and weight and manufacturing cost are reduced. - For convenience in explanation and accurate definition in the appended claims, the terms upper or lower, front, and etc. are used to describe features of the exemplary embodiments with reference to the positions of such features as displayed in the figures.
- The foregoing descriptions of specific exemplary embodiments of the present invention have been presented for purposes of illustration and description. They are not intended to be exhaustive or to limit the invention to the precise forms disclosed, and obviously many modifications and variations are possible in light of the above teachings. The exemplary embodiments were chosen and described in order to explain certain principles of the invention and their practical application, to thereby enable others skilled in the art to make and utilize various exemplary embodiments of the present invention, as well as various alternatives and modifications thereof. It is intended that the scope of the invention be defined by the Claims appended hereto and their equivalents.
