Description

Technical Field

[0001] The present invention relates to an air conditioner for a vehicle, and more particularly, to an air conditioner for a vehicle that has a smaller size by comprising an air conditioning module and a cooling module integrally formed with each other, thereby having increased space utilization in the engine compartment and further improved manufacturability. Background Technology

[0002] A typical air conditioning system for a vehicle may include the following components connected via refrigerant lines: a compressor that compresses and delivers refrigerant, a condenser that condenses the high-pressure refrigerant delivered from the compressor, an expansion device that throttles the refrigerant condensed and liquefied by the condenser, and an evaporator that evaporates the low-pressure liquid refrigerant throttled by the expansion device by exchanging heat with the air blown into the vehicle interior, thereby cooling the air discharged into the vehicle interior by utilizing the latent heat released when the refrigerant is evaporated, and so on.

[0003] The evaporator can be installed in an air conditioning housing, which is installed inside the vehicle and used to cool the interior. That is, the vehicle interior can be cooled when the air blown by the blower is cooled by latent heat and the cold air is discharged into the vehicle interior. This latent heat is released when the liquid refrigerant circulating in the evaporator is evaporated as it passes through the evaporator.

[0004] Alternatively, a heater core installed in the air conditioning housing and in which engine coolant circulates, or an electric heater installed in the air conditioning housing, can be used to heat the vehicle interior.

[0005] Meanwhile, the condenser can be installed at the front of the vehicle to dissipate heat while exchanging heat with the air.

[0006] In recent years, heat pump systems have been developed that use only a refrigeration cycle for air cooling and heating. For example... Figure 1 As shown, the heat pump system may include a cold air passage 11 and a hot air passage 12 separated within an air conditioning housing 10, an evaporator 4 for air cooling installed in the cold air passage 11, and a condenser 2 for air heating installed in the hot air passage 12. Here, an air outlet 15 for supplying air to the vehicle interior and an air outlet 16 for discharging air to the outside of the vehicle can be located at the outlet of the air conditioning housing 10. Additionally, a separately operated blower 20 can be installed at the inlet of the cold air passage 11 and the inlet of the hot air passage 12, respectively.

[0007] Therefore, in air-cooling mode, the cold air cooled as it passes through the evaporator 4 of the cold air passage 11 can be discharged into the vehicle interior through the air outlet 15 to cool the interior. Here, the hot air heated as it passes through the condenser 2 of the hot air passage 12 can be discharged to the outside of the vehicle through the air exhaust port 16.

[0008] In air heating mode, hot air heated as it passes through the condenser 2 of hot air passage 12 can be discharged into the vehicle interior through air outlet 15 to heat the interior. Here, cold air cooled as it passes through the evaporator 4 of cold air passage 11 can be discharged into the outside of the vehicle through air outlet 16.

[0009] However, in the prior art, the blower 20 can be positioned in both the cold air passage 11 and the hot air passage 12. Based on the air cooling or heating setting, it may be necessary to discharge air passing through the condenser 2 or evaporator 4 through an air exhaust port. Therefore, the air exhaust port 16 equipped with a control door may inevitably be located in each of the two positions. Consequently, the heat pump system may inevitably have an increased overall size.

[0010] Furthermore, the condenser 2 installed in the air conditioner casing may have low condensing performance due to its unavoidably small size. Therefore, the heat pump system may have problems with its cooling performance.

[0011] Meanwhile, the front-end module, including the bracket, cooling module, and headlights, can be positioned at the front of the vehicle. The cooling module can include a radiator, condenser, and fan shroud, and can exchange heat between the radiator and condenser via air blown from the front of the vehicle.

[0012] Therefore, it is necessary to assemble the air conditioner and the cooling module separately, and the areas where the air conditioner is installed to actually perform air conditioning and the areas where the condenser of the cooling module is installed may be far apart from each other, and therefore may be connected to each other via refrigerant lines.

[0013] In recent years, various new types of vehicles have been proposed, and in particular, there is an increasing demand for methods to effectively utilize the space in the engine compartment.

[0026] Additionally, in the air conditioner 1000 for a vehicle, the external air inlet 210 can be positioned below the air conditioner in the height direction and simultaneously positioned on one side of the air conditioner in the length direction.

[0038] Beneficial effects

[0040] Furthermore, in the air conditioner for a vehicle according to the present invention, external air introduced through the external air inlet can be supplied simultaneously by being divided into air flowing to the air conditioning module and air flowing to the cooling module, and the air conditioner can control the flow of internal air and external air supplied to the air conditioning module by using an internal / external air controller.

[0041] Furthermore, in the air conditioner for a vehicle according to the present invention, the air conditioning module has a first region and a second region positioned parallel to each other to increase space utilization and smoothly regulate the air inside the vehicle.

[0049] In the following, an air conditioner 1000 for a vehicle having the structure described above will be described in detail with reference to the accompanying drawings.

[0050] Figure 2 This is a perspective view of an air conditioner 1000 for a vehicle according to the present invention; Figure 3 This is a perspective view of an air conditioner 1000 for a vehicle according to the present invention; Figure 4 and Figure 5 These are views taken along directions AA' and BB' of the air conditioner 1000 for a vehicle according to the present invention; and Figure 6 This is a diagram illustrating the flow of internal and external air in an air conditioner for a vehicle according to the present invention.

[0051] In the air conditioner 1000 for a vehicle of the present invention, the air conditioning module M1 and the cooling module M2 can be integrally formed and positioned in the vehicle engine compartment.

[0052] First, the air conditioning module M1 can be a component for cooling and heating the interior of the vehicle, and the cooling module M2 can be a component including a radiator 720 and a fan shroud 710 that forms airflow through the radiator 720. Therefore, the air conditioner 1000 for a vehicle of the present invention does not require a process or space for separately installing the cooling module M2, because the cooling module M2, which should conventionally be located at the front of the vehicle, can be installed together with the air conditioning module M1 on the air conditioner, which is integrally formed with the cooling module M2.

[0053] In the radiator 720, coolant for cooling the engine can flow, and coolant for cooling various electronic components located in the engine compartment can also flow.

[0054] More specifically, the air conditioner 1000 for a vehicle of the present invention may be constructed of an outer shell 110 and an inner shell 120.

[0055] The housing 110 may be the external basic body of the air conditioner 1000 for a vehicle, and includes an external air inlet 210, an internal air inlet 220 and an air delivery unit 240.

[0056] The external air inlet 210 can be a space that serves as a specific through area of ​​the housing 110 for introducing external air. The air introduced through the external air inlet 210 can be supplied to the air conditioning module M1 and the cooling module M2.

[0057] The internal air inlet 220 can be a space that serves as a specific through area of ​​the housing 110 for introducing internal air, and the internal air can be introduced into the air conditioning module M1.

[0058] Here, the external air inlet 210 can be positioned vertically below the air conditioner. Therefore, external air can be introduced into the housing 110 while being supplied along its length. Some of the external air can pass through the cooling module M2, while the remaining external air can be selectively supplied to the air conditioning module M1. That is, in the cooling module M2, external air can be introduced into the area between the housing 110 and the inner housing 120 through the external air inlet 210, which is positioned vertically below the air conditioner and simultaneously along one side of the air conditioner in the length direction, and then pass through the cooling module M2 to be discharged to the other side of the air conditioner in the length direction. In other words, the external air introduced through the external air inlet 210 can pass through the fan shroud 710 to exchange heat with the coolant in the radiator 720.

[0059] (exist Figure 6 In the diagram, solid arrows indicate the flow of external air, while dashed arrows indicate the flow of internal air.

[0060] The cooling module M2 can be positioned across the entire area of ​​the housing 110 in the width direction to fully ensure the heat exchange performance of the radiator 720. For this purpose, the external air inlet 210 can also be positioned as elongated in the width direction.

[0061] Here, the air conditioning module M1 can be used by introducing outside air through the outside air inlet 210. That is, the air conditioning module M1 can cool or heat its interior by exchanging heat with the outside air or internal air introduced through the outside air inlet 210 or the internal air inlet 220, respectively. The flow of outside air and internal air into the air conditioning module M1 can be controlled by the internal / outside air controller 230, the specific structure of which is described again below.

[0062] The air delivery section 240 may be a specific through area of ​​the housing 110 for delivering air that is heat-exchanged in the air conditioning module M1 (or air used to cool the interior of the vehicle).

[0063] Here, the internal air inlet 220 and the air delivery section 240 can be positioned on the upper side of the housing 110, and are parallel to each other in the width direction.

[0064] The inner shell 120 may be a space separated from the outer shell 110 to position the air conditioning module M1 in the inner shell, and components for allowing air to be introduced into the air conditioning module M1, an evaporator 510 for air cooling, a heat exchanger 520 for air heating, etc., may be constructed in the inner shell.

[0065] In other words, the air conditioning module M1 located in the inner shell 120 may have a first region 101 and a second region 102 that are positioned parallel to each other in the width direction.

[0066] The first zone 101 may be equipped with an internal / external air controller 230 and a blower 400 to introduce external or internal air into the air conditioning module M1.

[0067] The internal / external air controller 230 may include a through section 210a, an internal air inlet 220, and a first control door 231. The through section is a specific through area of ​​the inner shell 120 for introducing some of the external air introduced through the external air inlet 210 into the first region 101. The first control door is used to control the flow of external air and internal air introduced through the through section 210a and the internal air inlet 220, respectively.

[0068] In the air conditioner 1000 for a vehicle, outside air can pass through the cooling module M2 via an outside air inlet 210 located below the inner housing 120 (i.e., in the region between the inner housing 120 and the outer housing 110), flowing from one side of the portion of the first region 101 along its length to the other. Then, by operating the first control door 231 of the internal / external air controller 230, some of the outside air can be supplied to the first region 101 of the air conditioning module M1 through the through portion 210a.

[0069] The blower 400 can introduce external or internal air into the air conditioning module M1.

[0070] Additionally, the air conditioning module M1 may include a filter 300 positioned between the internal / external air controller 230 and the blower 400 of the first zone 101, and the filter 300 may have a form that allows the filter to be replaced, a form that allows the filter to electro-collect dust, etc., and is not limited to any particular form.

[0071] The second zone 102 may be provided with an evaporator 510 for air cooling and a heat exchanger 520 for air heating to exchange heat with the air supplied from the first zone 101, and then the heat-exchanged air is supplied through the air conveying section 240.

[0072] The evaporator 510 can cool the air discharged into the vehicle interior through the air delivery section 240. Here, when air cooling is performed, refrigerant in a low-temperature, low-pressure, and humid state can be supplied to the evaporator 510, and the air can be cooled as it passes through the evaporator 510 before being discharged into the vehicle interior. On the other hand, when air heating is performed, refrigerant can be withheld from the evaporator 510, so that the temperature does not change even as the air passes through the evaporator 510.

[0073] The heat exchanger 520 can heat the air discharged into the vehicle interior through the air delivery section 240. Here, the heat exchanger 520 can be a heater core to which heated coolant is supplied, or it can be an internal heat exchanger 520 of a heat pump system.

[0074] Here, the second zone 102 may also be provided with a temp door 540, which determines whether the air conditioning air passing through the evaporator 510 passes through the heat exchanger 520.

[0075] The heat exchanger 520 can be positioned horizontally. Horizontally refers to a direction perpendicular to the height direction, and the space in which external air is introduced can be positioned outside and below the inner casing 120. The cooling module M2 can be positioned below this space to reduce the overall size of the air conditioner. Here, in the cooling module M2, considering the size of the radiator 720, the radiator 720 and the fan shroud 710 can be positioned below the heat exchanger 520, and both can be positioned with a downward-sloping side in the horizontal direction.

[0076] The air conditioner 1000 for a vehicle of the present invention may further include an auxiliary heating heat exchanger 530, which is positioned at the rear of the heat exchanger 520 in the airflow direction. The auxiliary heating heat exchanger 530 may be a component that performs air heating together with the heat exchanger 520, and may use various types including positive temperature coefficient (PTC) heating devices. The auxiliary heating heat exchanger 530 may also be positioned horizontally like the heat exchanger 520, and may be positioned above and parallel to the heat exchanger 520 positioned at the rear of the air conditioner in the airflow direction.

[0077] In the air conditioner 1000 for a vehicle of the present invention, the cooling module M2 may further include an external heat exchanger 730.

[0078] In this invention, the external heat exchanger 730 may be another heat exchanger 520 located outside the inner shell 120, and may be a condenser for air cooling performed by the evaporator 510 as the refrigerant sequentially passes through the compressor, condenser, expansion device, and then through the evaporator 510.

[0079] Alternatively, the external heat exchanger 730 may be a variable heat exchanger 520 that functions variably in the heat pump system. The variable external heat exchanger 730 may not be a component for cooling or heating the air used for actual cooling and heating, and may condense the refrigerant supplied to the evaporator 510 based on an air cooling setting, or evaporate the refrigerant supplied to the heat exchanger 520 based on an air heating setting.

[0080] The external heat exchanger 730 can be positioned in the lower region of the air conditioner, adjacent to and parallel to the radiator 720, and positioned corresponding to the second region 102, in which no relatively large blower 400 is provided. That is, the external heat exchanger 730 can be positioned below the inner casing 120, and can also be installed in the water tank of the radiator 720 or the fan shroud 710 of the cooling module M2, as in the prior art, or can be installed in the inner casing 120 or the outer casing 110. Figure 5 In this case, the external heat exchanger 730 may have an upper side supported by the inner shell 120 and a lower side mounted in the outer shell 110 and supported by the outer shell, and may be positioned in a variety of other ways.

[0081] When the air conditioner includes an external heat exchanger 730 located in the air conditioner, the air conditioner may include an engine compartment air inlet 250 and a second control door 251 for controlling the flow of external air and engine compartment air introduced through the external air inlet 210 and the engine compartment air inlet 250, respectively, such that air inside the engine compartment selectively and sequentially passes through the external heat exchanger 730 and the radiator 720.

[0082] The engine compartment air inlet 250 may be adjacent to the external air inlet 210 of the second region 102 and the through portion for introducing engine compartment air into the engine compartment air inlet. The second control door 251 may selectively control the opening degree of the engine compartment air inlet 250 and the external air inlet 210.

[0083] In other words, the external air inlet 210 can be positioned above the first region 101 and the second region 102 to be elongated in the width direction. When supplied, external air introduced through the external air inlet 210 positioned corresponding to the first region 101 can be supplied to the cooling module M2 or the air conditioning module M1, and external air selectively introduced through the external air inlet 210 positioned corresponding to the second region 102 can sequentially pass through the external heat exchanger 730 and the radiator 720.

[0084] Specifically, in winter when the outside temperature is low, the air inside the engine compartment can be heated by the operation of various electronic components and maintained at a temperature higher than the outside temperature. In this way, the engine compartment air inlet 250 and the second control door 251 can be positioned in the air conditioner 1000 for vehicles of the present invention and supply the air inside the engine compartment to the outer casing 110 to improve the evaporation performance (or heat absorption) of the external heat exchanger 730, thereby further improving the air heating performance of the heat exchanger 520.

[0085] As described above, the air conditioner 1000 for vehicles of the present invention has a smaller size by including an air conditioning module M1 and a cooling module M2 integrally formed with each other, which further improves manufacturability, smoothly regulates the air inside the vehicle, and easily cools electronic components, etc.

[0086] This invention is not limited to the embodiments described above, and can be applied in various ways. Furthermore, various modifications can be made to this invention by those skilled in the art without departing from the spirit of the invention as claimed in the claims.
