Description

Technical Field

[0001] The present invention relates to an integrated cooling module for use in a vehicle cooling system, and more specifically, to such an integrated cooling module in which components are integrated with a manifold to eliminate hoses or pipes and reduce the size and weight of the entire cooling system, and the manifold extends in the direction of gravity to advantageously store coolant therein and centrally mount components, and an internal heat exchanger is provided in the manifold to maximize space efficiency. Background Technology

[0002] In recent years, with increasing attention to energy efficiency and environmental pollution, there has been a need to develop environmentally friendly vehicles that can largely replace internal combustion engine vehicles. Environmentally friendly vehicles are generally classified into electric vehicles that operate using fuel cells or electricity as their power source, and hybrid vehicles that operate using both an engine and a battery.

[0003] Unlike air conditioning systems used in conventional vehicles, stand-alone heaters are not used in environmentally friendly electric or hybrid vehicles. Air conditioning systems used in environmentally friendly vehicles typically refer to heat pump systems.

[0004] Meanwhile, electric vehicles generate power by converting the energy produced by the chemical reaction between oxygen and hydrogen into electrical energy. During this process, heat is generated through the chemical reaction within the fuel cell, so effectively removing this heat is essential to ensure the fuel cell's performance.

[0005] Furthermore, hybrid vehicles generate driving force by operating an engine that uses conventional fuel and a motor that operates using electricity supplied from a fuel cell or battery. Therefore, to ensure motor performance, it is necessary to effectively remove the heat generated from the fuel cell or battery and the motor.

[0006] Therefore, in hybrid or electric vehicles in related technologies, the battery cooling system needs to be constructed as a separate closed loop together with the cooling system and heat pump system in order to prevent the motor, electrical components, fuel cell and battery from overheating.

[0007] For this reason, the problem is that the size and weight of the cooling module located at the front of the vehicle are increased, and the layout of the connecting pipes used to supply refrigerant or coolant to the heat pump system, cooling device and battery cooling system in the engine compartment is complicated.

[0042] The invention will be described below with reference to the accompanying drawings.

[0043] Figure 1 This is a perspective view of an example cooling module according to the invention, viewed from the top front side, and Figure 2 When viewed from the bottom rear side Figure 1 A perspective view of the integrated cooling module 10 of the present invention. As shown in the figure, the integrated cooling module 10 of the present invention broadly includes a manifold 100 and a plurality of components 200 mounted on the manifold.

[0044] In this invention, component 200 is integrated with manifold 100. Manifold 100 provides installation space in which multiple components 200 can be installed. Manifold 100 has a refrigerant passage in which refrigerant can flow. Manifold 100 may have a coolant storage section in which coolant can be stored and flows.

[0045] Component 200 is a constituent element of the vehicle cooling system. In this invention, the component may be one or more components selected from the condenser COND, the cooler, the PT sensor, the expansion valve EXV, and the water pump EWP. As described below, the internal heat exchanger IHX may be disposed in the manifold 100.

[0046] A condenser (COND) is a heat exchanger configured to condense gaseous refrigerant into liquid refrigerant. A cooler is a heat exchanger configured to remove heat from the liquid refrigerant. A PT sensor (pressure / temperature sensor) is a sensor configured to measure the pressure and temperature of the refrigerant. An expansion valve (EXV) is a valve configured to evaporate liquid refrigerant by reducing its pressure. A water pump (electric water pump (EWP)) is an electric pump configured to pressurize and deliver the coolant. An internal heat exchanger (IHX) is a heat exchanger configured to allow the high-temperature liquid refrigerant and the low-temperature gaseous refrigerant to exchange heat with each other.

[0047] Component 200 is mounted on manifold 100 and constitutes integrated cooling module 10. In this case, component 200 can be mounted to communicate with at least one of the coolant storage section and the refrigerant passage provided in manifold 100. More specifically, component 200 is mounted to communicate with a mounting port corresponding to a component formed in manifold 100 and communicating with the refrigerant passage mounting port and a coolant storage section mounting port formed in manifold 100 and communicating with the coolant storage section. Therefore, component 200 can communicate with at least one of the refrigerant passage and the coolant storage section.

[0048] In the following text, the manifold 100 of the present invention will be described first. Figure 3 This is a front perspective view of a manifold according to an example of the present invention. Figure 4 yes Figure 3 The rear-view stereoscopic view, and Figure 5 yes Figure 3 An exploded 3D diagram.

[0049] As shown in the figure, the manifold 100 of the present invention may include a coolant storage section 110 in which coolant can be stored and flows. The manifold 100 may have a refrigerant passage 120 disposed around the coolant storage section 110, allowing refrigerant to flow through it. That is, in a vehicle cooling system, the manifold 100 of the present invention provides space in which components are centrally mounted at the point where the main circuit through which the refrigerant circulates and the secondary circuit through which the coolant circulates intersect. The manifold 100 is used to supply refrigerant and coolant to the components, requiring heat exchange between the refrigerant and coolant, and the manifold 100 functions as a reservoir for replenishing and storing the refrigerant and coolant. The coolant storage section 110 and the refrigerant passage 120 of the manifold 100 may correspond to a portion of the main circuit and a portion of the secondary circuit.

[0050] The coolant reservoir 110 can be configured to be completely hollow within the manifold, allowing coolant to be stored and flow within the hollow interior. The refrigerant passage 120 can be configured to have a flow path formed within the structure surrounding the coolant reservoir 110 in the manifold 100, allowing refrigerant to flow along the flow path. However, the structures of the coolant reservoir 110 and the refrigerant passage 120 are for illustrative purposes only, and the invention is not limited thereto. For example, the coolant reservoir 110 can be provided in the form of a recess in a portion of the manifold. The refrigerant passage 120 can be configured such that a separate structure (such as a pipe or conduit) capable of defining a flow path is mounted on the outer or inner circumferential surface of the manifold.

[0051] Simultaneously, the manifold 100 of the present invention can extend along the direction of gravity. For example, as... Figure 3 As shown, the manifold 100 can have an elongated quadrilateral prism shape. The length of the manifold in the height direction (i.e., the direction of gravity) can be appropriately designed taking into account the relationship between the components 200 mounted on the manifold 100, and in particular, is designed to correspond to the lengths of the condenser and the coolant. The manifold 100 can be completely hollow at the center of the interior of the quadrilateral prism structure, allowing coolant to be stored within the manifold 100. The manifold 100 can have refrigerant channels formed in the structure constituting the manifold 100, allowing refrigerant to flow within the manifold 100. In the above-described invention, the manifold can extend in the direction of gravity to advantageously store coolant therein and more centrally mount components, thereby significantly reducing the space occupied by the integrated cooling module in the limited space of the engine compartment.

[0052] refer to Figure 5The manifold 100 of the present invention may include a first manifold 100A, a second manifold 100B, and a third manifold 100C. More specifically, the manifold 100 may have a structure in which the first manifold 100A, the second manifold 100B, and the third manifold 100C are stacked and connected to each other in an upward / downward direction. Furthermore, a first gasket 103-1 may be disposed between the first manifold 100A and the second manifold 100B to seal the portion between the first and second manifolds, and a second gasket 103-2 may be disposed between the second manifold 100B and the third manifold 100C to seal the portion between the second and third manifolds. Alternatively or additionally, the first manifold 100A, the second manifold 100B, and the third manifold 100C may be stacked and connected to each other by methods such as brazing, structural adhesive, mechanical fastening, or welding. Meanwhile, the first manifold 100A, the second manifold 100B, and the third manifold 100C may all be made of materials such as aluminum, thermoplastic, or stainless steel, depending on the manufacturing method.

[0053] The second manifold 100B can be hollow, and the coolant storage section 110 can be positioned within the hollow interior. The first manifold 100A and the third manifold 100C can be configured to cover and enclose one side and the other side of the hollow interior of the second manifold 100B, respectively. That is, the manifold 100 can have a three-level structure, including the second manifold 100B corresponding to the main body and having an elongated pipe shape, and the first manifold 100A and the third manifold 100C respectively disposed above and below the second manifold 100B to enclose it. Therefore, the coolant storage section 110, capable of storing coolant, can be disposed within the hollow interior of the second manifold 100B.

[0054] Furthermore, a refrigerant passage 120, in which refrigerant can flow and circulate, can be formed independently of the coolant storage section 110 and disposed in the structure constituting the second manifold 100B, i.e., disposed within the housing of the second manifold. The refrigerant passage 120 can be formed by hollowing out the interior of the housing along the pipeline to allow refrigerant to flow between components (e.g., in the case of the invention, between the condenser, the cooler, the expansion valve, and the PT sensor), which defines a main circuit among the components mounted on the manifold. Therefore, the components defining the main circuit are fluidly connected.

[0055] Furthermore, to improve the space utilization of the manifold 100, the refrigerant passage 120 connected to the refrigerant passage 120 formed in the second manifold 100B can be further formed in the first manifold 100A, the third manifold 100C, and the second manifold 100B. That is, most of the refrigerant passage 120 of the entire manifold 100 is formed in the housing of the second manifold 100B, and the refrigerant passage 120 can extend from the refrigerant passage 120 and form in the housings of the first manifold 100A and the third manifold 100C. Therefore, the component 200 can be additionally installed in the first manifold 100A and the third manifold 100C. For example, as... Figure 1 and Figure 3 As shown, at least a portion of the refrigerant passage is formed in the first manifold 100A, allowing a PT sensor communicating with the corresponding refrigerant passage to be installed in the first manifold. As described below, a connection port 129 can be provided in the first manifold, allowing the refrigerant passage 120 of the manifold 100 to communicate with the outside via the corresponding refrigerant passage.

[0056] Additionally, the second manifold 100B may have a mounting structure 150, on which the water pump EWP can be mounted. (See reference) Figure 4 The mounting structure 150 can be provided in the form of a recess to accommodate the end side of the water pump connected to the manifold. Because the water pump pressurizes the coolant, it receives high pressure. The mounting structure being provided in the form of a recess as described above allows the water pump to be securely mounted, which helps to withstand the high pressure. Therefore, the seal between the manifold and the water pump can be strengthened, thereby preventing coolant leakage.

[0057] A coolant inlet port 111, formed through the first manifold 100A, can be formed in the first manifold 100A. Therefore, coolant can be replenished to the coolant storage section 110 by introducing coolant into it. In addition, a coolant inlet port closure 112 can be provided in the coolant inlet port 111 and configured to close the coolant inlet port 111, so that the coolant storage section 110 can remain closed during normal times.

[0058] One or more support legs 102 may be provided on the third manifold 100C. One side of each support leg 102 may be connected to the third manifold 100C and has a structure extending from one side to the other. As shown, three support legs 102 may be provided to provide overall balanced support for the manifold 100. Fastening holes may be formed at the other end of each support leg 102 and bolted to the support leg 102 and the support surface on which the manifold 100 is mounted. The support legs 102 may be manufactured simultaneously with and integrated with the third manifold 100C. Alternatively, the support legs 102 may be manufactured separately from and connected to the third manifold 100C.

[0059] refer to Figure 5 In this invention, the internal heat exchanger IHX can be disposed within the manifold 100, that is, within the coolant storage section 110. Specifically, as shown, the internal heat exchanger IHX can be a plate-type internal heat exchanger P-IHX. The internal heat exchanger IHX is mounted and connected to the upper part of the third manifold 100C, allowing the internal heat exchanger IHX and the manifold 100 to be integrated. Because the internal heat exchanger IHX is disposed within the coolant storage section 110, the refrigerant flowing within the internal heat exchanger IHX and the coolant surrounding the internal heat exchanger IHX can exchange heat with each other. As described above, the coolant storage section can be disposed within the manifold, and the internal heat exchanger can be disposed within the coolant storage section, thereby maximizing space efficiency.

[0060] The specific connection between manifold 100 and component 200 will be described in more detail below.

[0061] As described above, component 200 can be mounted to communicate with at least either the coolant reservoir 110 and the refrigerant passage 120 formed in manifold 100. For this purpose, manifold 100 may have a first mounting port 115 and a second mounting port 125, the first mounting port 115 being configured to allow communication between the coolant reservoir 110 and component 200, and the second mounting port 125 being configured to allow communication between the refrigerant passage 120 and component 200. Return to Reference Figure 3 and Figure 4 Multiple first mounting ports 115 and multiple second mounting ports 125 are formed in the manifold 100. Therefore, component 200 can be fluidly connected to the coolant storage section 110 and the refrigerant passage 120.

[0062] In this configuration, one of the components 200 may be fluidly connected to the first mounting port 115 and the second mounting port 125, allowing coolant and refrigerant to flow therein. More specifically, within the component, a cooler is connected to both the first mounting port 115 and the second mounting port 125, allowing coolant and refrigerant to flow therein, such that the coolant can be cooled by the refrigerant, or the refrigerant can be cooled by the refrigerant.

[0063] Additionally, the water pump EWP can be fluidly connected to the coolant storage section 110 via the first mounting port 115, and the condenser COND, PT sensor, and expansion valve EXV can be fluidly connected to the refrigerant passage 120 via the second mounting port 125, respectively. Therefore, the first mounting port 115 and the second mounting port 125 can be appropriately located in the manifold 100.

[0064] Simultaneously, two coolers and two water pumps (EWP) can be installed on the manifold 100 of the present invention. In other words, the integrated cooling module 10 of the present invention can be a heat exchange module including two coolers and two water pumps (EWP). (Return to Reference) Figure 1 and Figure 2 The integrated cooling module 10 of the present invention can have a structure in which a first cooler (cooler 1) is mounted on one side surface of a manifold, a second cooler (cooler 2) is mounted on the opposite side surface, and a first water pump (EWP 1) and a second water pump (EWP 2) are respectively located on the transverse surface between the first cooler (cooler 1) and the second cooler (cooler 2). In this case, the first cooler and the second cooler (cooler 1 and cooler 2) can correspond to the first water pump and the second water pump (EWP 1 and EWP 2), respectively. For example, as described below, coolant that has exchanged heat while circulating through the first cooler (cooler 1) can be introduced into the first water pump (EWP 1) and discharged to the outside. Coolant that has exchanged heat while circulating through the second cooler (cooler 2) can be introduced into the second water pump (EWP 2) and discharged to the outside. For this purpose, the internal space of the coolant storage section 110 can be divided into two or more spaces by a separating wall.

[0065] Furthermore, the manifold 100 of the present invention may have one or more first connection ports 119 that allow the coolant storage section 110 to communicate with the outside, and one or more second connection ports 129 that allow the refrigerant passage 120 to communicate with the outside. In this case, the term "external" may refer to other heat exchange components in the entire cooling pipeline of the vehicle cooling system, such as internal condensers other than the integrated cooling module of the present invention, such as condensers, evaporators, external heat exchangers (OHX), compressors, etc. The first connection ports 119 and second connection ports 129, as well as other external components, may be fluidly connected to each other by means of valves or pipes.

[0066] For example, such as Figure 4As shown, the manifold 100 of the present invention can be configured such that a second connection port 129 can be formed in the upper part of the manifold 100 and connected to an external compressor COMP, and a first connection port 119 can be formed around the lateral surface of the manifold 100 through which a water pump EWP is mounted, thereby defining a closed loop with an external secondary circuit. More specifically, two second connection ports 129 can be provided, one of which serves as a refrigerant inlet port through which refrigerant can be introduced from the outside, and the other of which serves as a refrigerant discharge port through which refrigerant can be discharged to the outside. A single first connection port 119 can be provided and used as a coolant inlet port through which coolant is introduced from the outside. Furthermore, coolant in the coolant storage unit 110 can be discharged to the outside via the water pump EWP through a coolant discharge port 118 having a side connected to the water pump EWP.

[0067] at the same time, Figure 6 It is shown again Figure 1 The figure shows the condenser COND and the cooler in the length direction L, width direction W, and height direction H. As shown, in the integrated cooling module of the present invention, the condenser COND and the cooler can be arranged such that the length direction L of the condenser COND and the cooler is parallel to the direction of gravity. That is, the condenser COND and the cooler can be mounted on the manifold 100 such that the length direction L is perpendicular to the bottom surface and parallel to the direction of gravity. Therefore, the condenser COND and the cooler can be arranged parallel to each other. This is to widely distribute the load in the longitudinal direction of the condenser and the cooler when the condenser and the cooler are relatively heavy. Therefore, damage to sealing auxiliary materials such as O-rings caused by deterioration of the parts connected / attached to the manifold (i.e., excessive eccentric load, bending stress, etc.) can be prevented to the greatest extent. In addition, since the load is widely distributed, stability and excellent NVH performance can be ensured during maintenance.

[0068] The refrigerant circulation path and coolant circulation path in the integrated cooling module will be described below. Figure 7 This is a diagram illustrating the refrigerant circulation path and an example of the coolant circulation path in a cooling system. Figure 8 It is a schematic diagram illustrating the refrigerant circulation path according to an example of the present invention, and Figure 9 This is a diagram schematically illustrating a coolant circulation path according to an example of the invention.

[0069] refer to Figure 8The refrigerant is introduced from the external compressor COMP through the second connection port 129 into the refrigerant passage 120 and then into the condenser COND (A1). Afterward, the refrigerant passes through the condenser COND and is introduced into the internal heat exchanger IHX in the manifold (A2). The refrigerant passes through the internal heat exchanger IHX and is distributed to the first expansion valve and the second expansion valve (EXV 1 and EXV 2) (A3). Subsequently, the refrigerant passes through the first expansion valve and the second expansion valve (EXV 1 and EXV 2) and is introduced into the first and second refrigerators (refrigerator 1 and refrigerator 2), where heat exchange is performed (A4). The refrigerant can move along the refrigerant passage to the second connection port 129 and is discharged into the condenser COND through the second connection port 129 (A5). In this case, the refrigerant that has passed through the first and second refrigerators (refrigerator 1 and refrigerator 2) can further pass through the accumulator ACCU.

[0070] refer to Figure 9 The coolant is introduced into the coolant storage section 110 through the first connection port 119 (coolant inlet), which serves as the coolant inlet port, and then into the first and second coolers (cooler 1 and cooler 2) (B1). The coolant, having been introduced into the first cooler (cooler 1) and undergone heat exchange, is introduced into the first water pump (EWP 1) and then discharged to the outside through the coolant discharge port 118 (coolant outlet 1) (B2-1). Thereafter, the coolant undergoes heat exchange while passing through the battery pack, PE module, cabin cooler, etc. (B3). Subsequently, the coolant can be introduced into a pump, etc., and then into the integrated cooling module of the present invention. The coolant, having been introduced into the second cooler (cooler 2) and undergone heat exchange, is introduced into the second water pump (EWP 2) and then discharged to the outside through the coolant discharge port 118 (coolant outlet 2) (B2-2). Thereafter, the coolant undergoes heat exchange while passing through the battery pack, PE module, cabin cooler, etc. Subsequently, the coolant can be introduced into a pump or the like, and then into the cooling module of the present invention.

[0071] According to the integrated cooling module of the present invention as described above, the components and manifolds are centrally integrated to form a cooling circulation loop. Therefore, hoses or pipes can be eliminated through the integration of components constituting the cooling system, thereby achieving miniaturization and weight reduction of the entire cooling system. Furthermore, mounting structures (brackets, bolts, nuts, etc.) used for installing components in the vehicle can be eliminated, which reduces the number of components and assembly processes when constructing the cooling system.

[0072] Furthermore, the manifold of the present invention can extend in the direction of gravity to advantageously store coolant therein and to more centrally mount components, thereby reducing the space occupied by the integrated cooling module. Additionally, an internal heat exchanger can be located within the manifold, thereby maximizing space efficiency.

[0073] Although embodiments of the invention have been described with reference to the accompanying drawings, those skilled in the art will understand that the invention can be practiced in any other specific form without altering its technical spirit or essential characteristics. Therefore, it should be understood that the above embodiments are illustrative in all respects and do not limit the invention.
