Description

BACKGROUND OF THE INVENTION Field of invention The present invention relates to a cooling module for a vehicle. In particular, the present invention relates to a cooling module for a vehicle comprising a water-cooled condenser arranged in a top tank of a radiator, which cools the coolant by heat exchange with outside air, and an air-cooled condenser arranged on or in front of the radiator. Description of related technology Typically, an air conditioning unit for a vehicle maintains a suitable cabin temperature, regardless of the ambient temperature, and creates a comfortable interior environment. Such an air conditioning unit has a compressor that compresses a refrigerant, a condenser that condenses and liquefies the refrigerant compressed by the compressor, an expansion valve that rapidly expands the refrigerant that has been condensed and liquefied by the condenser, and an evaporator that evaporates the refrigerant that has been expanded by the expansion valve, so that cool air is supplied to the cabin or passenger compartment in which the air conditioning unit is installed, utilizing latent heat of vaporization. However, if a refrigerant condenser is used in a conventional air conditioning system as described above to condense the refrigerant, the refrigerant is cooled by means of the condenser, and the refrigerant temperature of the condenser outlet is increased, and therefore there is a problem that energy consumption is increased. Furthermore, since the heat capacity of the coolant condenser is greater than that of an air-cooled condenser, the condensing pressure is reduced, and since the temperature difference between the coolant and the refrigerant is small and the coolant temperature is higher compared to the ambient air, it is difficult to achieve subcooling, and therefore there is a disadvantage that the overall cooling performance is worsened. A cooling fan and a large-capacity radiator are necessary to avoid this, so the layout in a narrow engine compartment is disadvantageous, and there is a disadvantage that the overall weight and cost are increased. Furthermore, a coolant condenser, which is located in a confined engine compartment, must be positioned on a rear side of a fender or engine compartment, and it is difficult to secure sufficient space, and therefore the layout and piping are complicated, the assembly and mounting characteristics are worsened, the performance is worsened by the heat of the engine compartment, and the flow resistance of the coolant is increased, thus increasing the energy consumption of the compressor. Furthermore, in an environmentally friendly vehicle with an engine, an electrical energy component and a stack, the coolant cools the components and is then fed to the condenser, and the temperature of this is increased, and therefore there is a problem that the condensing capacity of the coolant is deteriorated. Document US 2011 / 0 232 868 A1 describes a combined heat exchanger with a first air-cooled heat exchanger for cooling a coolant in an automobile and a second air-cooled heat exchanger for cooling a refrigerant for vehicle air conditioning. The publication JP 2005- 343 221 A describes a cooling system for a hybrid vehicle to reduce the capacity of a heat exchanger in the engine compartment. The publication JP 2007-3027A describes an oil cooler with which a patch plate can be easily and stably attached, while all element parts have the same molded parts. Further coolers are described in the publications KR 10 2010 0 009 817 A , DE 10 2008 050 611 A1 , US 1 036 484 A and DE 10 2011 110 963 A1.

The cooling module also has a condensing section in which two plates are combined to form a refrigerant passage, the refrigerant passages being arranged at a predetermined distance from each other, a refrigerant inlet formed at one end of the condensing section to connect with the refrigerant passage and which connects to the refrigerant line on an outside of the second head tank, and a refrigerant outlet formed at the other end of the condensing section corresponding to the refrigerant inlet.to be connected to the refrigerant passage, and which is connected to the refrigerant line on an outer side of the second head tank. On the plate that is arranged between two plates on a first side, a transfer projection is integrally extended in the width direction of the condensing section towards both sides, and the transfer projection is designed to efficiently exchange the heat of the refrigerant passing through the refrigerant passage of the water-cooled condenser with the coolant inside the second head tank. An inlet can be formed on the first head tank to receive coolant, while an outlet corresponding to the inlet can be formed on the second head tank to discharge the coolant. The inlet and outlet can be located on opposite sides of the first head tank or the second head tank. A plurality of protrusions can be formed at a predetermined distance on an outer surface of a plate arranged under / of two plates on a first side, wherein the protrusions can contact an outer surface of the plate arranged on the other side of it in order to be connected. On the plate that is located on the other side of the two plates, a heat transfer projection can project integrally in a width direction of the condensing section towards both sides. The air-cooled condenser can be arranged longitudinally on the front side of the cooler. The air-cooled condenser can have a plurality of coolant tubes arranged at a uniform distance and be a fin-tube-type heat exchanger in which a transfer fin is formed between the coolant tubes. The air-cooled condenser can be divided in a vertical direction to allow sequential condensation, depending on the state of the refrigerant supplied from the water-cooled condenser. A receiving dryer can be formed integrally with the air-cooled condenser to separate gaseous refrigerant within the refrigerant. A receiving dryer can be arranged on the radiator to separate gaseous refrigerant from the refrigerant that condenses as it flows through the air-cooled condenser in a lateral direction of a vehicle, and connects the air-cooled condenser to the refrigerant line.

Furthermore, since the cooler is of an integrated type with a water-cooled condenser and an air-cooled condenser, the package function is improved, as the layout of a narrow engine compartment is simplified, space utilization efficiency is increased, weight is reduced, and manufacturing costs are also saved. Furthermore, since condensation pressure is reduced and condensation performance is improved, the necessary work can be reduced, and therefore the overall fuel consumption efficiency of a vehicle is improved. And, since a water-cooled condenser is located inside a head tank that stores cooled coolant, there is an effect that the coolant in it efficiently exchanges heat with the refrigerant.

Referring to the drawing, a cooling module for a vehicle 1 according to various embodiments of the present invention has a water-cooled condenser 20, which uses coolant as a heat exchange medium within a head tank of a radiator 10, and an air-cooled condenser 30, which uses outside air as a heat exchange medium at a front side of a radiator 10, such that the condensation pressure is reduced, the condensation performance is improved and the cooling performance is increased. Furthermore, since the cooling module 1 applies / mounts the water-cooled condenser 20 and the air-cooled condenser 30 on the cooler 10, a package function is improved and space utilization efficiency is also improved. For this purpose, a cooling module for a vehicle 1 according to various embodiments of the present invention, as shown in Fig. 1 and Fig. 2, has a radiator 10, a water-cooled condenser 20 and an air-cooled condenser 30. Initially, the radiator 10 is located at the front of a vehicle, and heated coolant, which cools an internal combustion engine or electronic devices, flows through the radiator 10. The coolant flows in the radiator 10 to be cooled by outside air while the vehicle is in motion. Here, a cooling fan is arranged on a rear side of the cooler 10 to supply the cooler 10 with outside air in such a way that the coolant is efficiently cooled. The cooler 10, which performs the above function, has a first head tank 11 which receives coolant, a second head tank 13 which is arranged at a predetermined distance from / to the first head tank 11 in order to discharge the coolant, as well as a plurality of pipes 15 which connect the first head tank 11 to the second head tank 13 and which are arranged at a uniform distance from each other, and a transfer fin P is arranged on it. This means that in the cooler 10, the heated coolant, which flows in the first head tank 11, passes / flows through the pipe 15 to be cooled by outside air, and the cooled coolant is discharged through the second head tank 13. Here, an inlet 12 is formed to receive coolant at the first head tank, and an outlet 14, which corresponds to the inlet 12, is formed to discharge coolant at the second head tank 13. The inlet 12 and the outlet 14 can be formed on opposite sides of the first head tank 11 and the second head tank 13, respectively, and based on a width direction of a vehicle, they are arranged on both sides, on the first head tank 11, which is arranged on an upper side, and on the second head tank 13, which in various embodiments is arranged on a lower side. The cooler 10 with this configuration is a fin-tube type heat exchanger, with the coolant flowing through the first head tank 11, the tube 15 and the second head tank 13 and being cooled by heat exchange with outside air. Here, the transfer fin (P) is formed between the tubes 15, and the heat transferred by the coolant flowing through the tube 15 is released to the outside. Meanwhile, in various embodiments it is described that the first and second head tanks 11 and 13 are arranged on an upper section and a lower section of the radiator respectively, but the invention is not limited to this, and the first and second head tanks 11 and 13 can be arranged on the two sides of the radiator 110 based on a width direction of a vehicle, in order to be connected by means of the pipes 116. In various embodiments, as shown in Fig. 3 and Fig. 4, the water-cooled condenser 20 receives refrigerant through a refrigerant line 21 and is formed by a plurality of plates 23 which are layered or stacked on top of each other within the second head tank 13, which receives the coolant which is cooled by means of the cooler 10. The water-cooled condenser 20 exchanges heat with cooled coolant, which flows into the second head tank 13 to condense refrigerant. Here, the water-cooled condenser 20 has a condensation section 22, a refrigerant inlet 27 and a refrigerant outlet 29, which are described below. First, two plates 23 are joined to form a set as a refrigerant passage 25 in the condensation section 22, and several sets of two plates 23 are prepared, and several passages 25 are arranged at a predetermined distance. Here, the condensation section 22 can have seven sets of refrigerant passages 25, which are formed by combining two plates 23, whereby seven sets of refrigerant passages can be layered. The refrigerant inlet 27 is formed at one end of the condensation section 22 to be connected to the refrigerant passage 25 and is connected to the refrigerant line 21 on an outside of the second head tank 13. Furthermore, the refrigerant outlet 29, which corresponds to the refrigerant inlet 27, is formed on the other side of the condensation section 22 to be connected to the refrigerant passage 25 and is connected to the refrigerant line 21 on an outside of the second head tank 14. Here, one plate 23, which is arranged on one side of two plates 23, has a plurality of projections 24 which are formed on one side with a predetermined distance, and the other plate 23, which is arranged on the other side, contacts a plate 23 via each projection 24. That is, the projection 24 is formed on an upper surface of the plate 23, which, based on the drawing, is arranged on an upper side in various embodiments, and the upper plate 23 is connected or combined with the lower plate 23 by means of the projection 24, in such a way that two plates are securely combined with each other. Furthermore, when the coolant flowing into the second head tank 13 passes through spaces formed by the respective projection 24, the flow path of the coolant is continuously / permanently changed by means of the projection, so that the heat exchange between the coolant and the refrigerant is carried out efficiently and the condensation rate or percentage of the refrigerant is increased. Meanwhile, a transmission projection 26 is integrally formed on the plate 23, which is arranged on the opposite side from the two plates 23, and the transmission projection 26 is formed on both sides in a lateral direction of the condensation section 22 towards the outside in various embodiments. It should be understood that such integral components can be monolithic. The transfer advantage 26 causes the heat of the refrigerant, which passes through the refrigerant passage 25 of the water-cooled condenser 20, to be efficiently exchanged with or transferred to the coolant within the second head tank 13. Fig. 5 is a view showing a coolant flow in a second head tank and a refrigerant flow passing through a water-cooled condenser according to various embodiments of the present invention. That is, as shown in Fig. 5, the water-cooled condenser 20 with the above configuration allows coolant to flow through a gap between two plates 23, and the projection 24 creates a flow resistance to increase a contact area with the plates 23, so that refrigerant passing through the refrigerant passage 25 efficiently exchanges heat with the coolant and the refrigerant condensation efficiency is increased. In addition, the transfer projection 26 transfers the heat transferred by the refrigerant passing through the refrigerant passage 25 to the coolant flowing within the second head tank 13. Meanwhile, in various embodiments it is described that the water-cooled condenser 20 is arranged in the second head tank 13, which according to various embodiments is arranged on a lower side with respect to the first head tank 11, but the invention is not limited to this, and the water-cooled condenser 20 can be arranged in a head tank which receives cooled coolant under the two-sided head tanks in a cross-flow type, which are arranged on both sides of the cooler 10. Furthermore, the air-cooled condenser 30 is connected to the water-cooled condenser 20 via the refrigerant line 21, receives primarily / initially condensed refrigerant from the water-cooled condenser 20 and is arranged on a front side with respect to the cooler 10 in order to further condense the refrigerant by heat exchange with outside air. Here, the air-cooled condenser 30 can be arranged in a longitudinal direction on a front side with respect to the cooler 10, a plurality of coolant tubes 31 are arranged therein at a uniform distance from each other, and this is a fin-tube type with a transmission fin (P) between the coolant tubes 31. The air-cooled condenser 30 can be separated or subdivided in a vertical direction in order to sequentially condense the refrigerant supplied by the water-cooled condenser 20, depending on the state of the refrigerant. For example, in a case where the air-cooled condenser 30 is divided into three stages according to various embodiments, when the refrigerant is supplied from the water-cooled condenser 20, superheated vaporous refrigerant is condensed at an upper section, humid or moist vaporous refrigerant is condensed at a middle section, and liquid refrigerant is subcooled at a lower section. The air-cooled condenser 30 described above is connected to the air-cooled condenser 20 by the refrigerant line 21 on one side of a width direction of a vehicle, and a receiving dryer 40, which separates gaseous refrigerant from condensed refrigerant, can be integrally formed thereon. Fig. 6 is a front view of a cooling module for a vehicle according to various embodiments of the present invention. Referring to Fig. 6, in a cooling module for a vehicle 100 according to various embodiments of the present invention, in a case in which the air-cooled condenser 120 is divided into two stages, moist vaporous refrigerant is cooled at an upper section to be condensed, and liquid refrigerant is subcooled at a lower section to be condensed. Here, a receiving dryer 140 is arranged in a width direction of a vehicle on one side of the radiator 110 to separate gaseous refrigerant from the refrigerant which has been condensed by means of the air-cooled condenser 120, and is connected to the air-cooled condenser 120 by the refrigerant line 121. Fig. 7 is a front view of a cooling module for a vehicle according to various embodiments of the present invention. Referring to Fig. 7, in a cooling module for a vehicle 200 according to various embodiments of the present invention, the air-cooled condenser 220 is not divided, and a receiving dryer 240 is arranged in a width direction of a vehicle on one side of the radiator 210, on the refrigerant line 221 between the water-cooled condenser 220 and the air-cooled condenser 230, and separates gaseous refrigerant from the refrigerant which has been condensed by the water-cooled condenser 220. Here, the water-cooled condenser 220 is connected in series with the air-cooled condenser 230 via the receiving dryer 240. Consequently, the liquid refrigerant discharged from the water-cooled condenser 220 is separated from the gaseous refrigerant by means of the receiving dryer 240, is fed to the air-cooled condenser 230 and is further condensed by means of the air-cooled condenser 230 by heat exchange with outside air. That is, as described above, the receiving dryer (40, 140, 240) is integrally formed on / at one side of the air-cooled condenser 30 or is integrally formed on / at one side of the radiator 110 and 210 based on a width direction of a vehicle. Consequently, a cooling module for a vehicle (1, 100, 200) according to various embodiments uses a coolant whose heat transfer coefficient is greater than that of outside air to condense refrigerant by means of the water-cooled condenser (20, 120, 220) in such a way that the condensation pressure of the refrigerant generated inside is reduced. And the air-cooled condenser (30, 130, 230) receives condensed refrigerant which passes through the water-cooled condenser (20, 120, 220), has separate sections which condense the refrigerant depending on its state, and discharges the refrigerant to the receiving dryer (40, 140), and also receives liquid refrigerant, from which gaseous refrigerant has been separated, from the receiving dryer (40, 140), and can further condense the liquid refrigerant. Furthermore, according to various embodiments of the present invention, after refrigerant discharged from the water-cooled condenser 220 has passed through the receiving dryer 240, the air-cooled condenser 230 receives the refrigerant in liquid form in order to cool the refrigerant using outside air. Consequently, the air-cooled condenser (30, 130, 230) can increase a temperature difference of refrigerant from the outside to achieve subcooling, and can reduce a total heat transfer of the refrigerant line (21, 121, 221). A cooling module for a vehicle (1, 100, 200) as described above, according to various embodiments of the present invention, reduces the condensation pressure as a benefit of a water-cooled type and achieves subcooling as a benefit of an air-cooled type to compensate for its disadvantages, and the water-cooled condenser (20, 120, 220) and the air-cooled condenser (30, 130, 230) are integrally provided on a front side (10, 110, 210) of the radiator or inside the second head tank (13, 113, 213) in such a way that the space utilization efficiency in an engine compartment is improved and its size is compact. Consequently, in a cooling module (1, 100, 200) for a vehicle according to various embodiments of the present invention, a water-cooled condenser (20, 120, 220), which uses coolant as a heat exchange medium in a head tank (13, 113, 213) of a radiator (10, 110, 210), is used, and an air-cooled condenser (30, 130, 230), which uses outside air as a heat exchange medium, is applied to a front side of a radiator (10, 110, 210), so that the condensation pressure is reduced, the condensation power is increased, and the cooling power is improved while refrigerant is condensed. Furthermore, since a cooler (10, 110, 210) is of an integrated type with a water-cooled condenser (20, 120, 220) and an air-cooled condenser (30, 130, 230), a package function is improved, as a layout of a narrow engine compartment is simplified, space utilization efficiency is increased, weight is reduced and manufacturing costs are also saved. Furthermore, since condensation pressure is reduced and condensation performance is improved, the necessary work can be reduced, and therefore the overall fuel consumption efficiency of a vehicle is improved. Furthermore, since a water-cooled condenser (20, 120, 220) is arranged inside a second head tank (13, 113, 213) which stores cooled coolant, there is an effect that the coolant efficiently exchanges heat with the refrigerant in it.
