Description

Vehicle integrated refrigerant module and integrated heat management module {VEHICLE'S INTERGRATED REFRIGERANT MODULE AND INTERGRATED THERMAL MANAGEMENT MODULE}

The present invention relates to an integrated refrigerant module and an integrated heat management module for a vehicle. More specifically, the present invention relates to an integrated refrigerant module and an integrated heat management module for a vehicle, and more specifically, to improve vibration insulation characteristics by simplifying the refrigerant transfer path in the air conditioner refrigerant module piping through a modular structure by adding an air conditioner refrigerant module to the coolant module. It is about a vehicle's integrated refrigerant module and integrated heat management module to secure competitiveness in terms of cost and weight by reducing the number of parts such as mufflers on the piping side.

Recently, due to environmental issues related to internal combustion engine vehicles, the spread of eco-friendly vehicles such as electric vehicles is expanding. In the case of existing internal combustion engine vehicles, the interior can be heated using the engine's waste heat after the engine is running, so no separate energy for heating is required, but in the case of eco-friendly vehicles such as electric vehicles, there is no heat source such as an engine. Separate energy is required for heating.

In the case of interior space, batteries, and electrical components applied to eco-friendly vehicles such as electric vehicles, technology is needed to utilize energy as efficiently as possible while satisfying the functions of each component. Accordingly, the concept of integrated thermal management of vehicles is being proposed to increase thermal efficiency by performing thermal management independently for each component and simultaneously integrating thermal management of the entire vehicle.

Conventionally, the coolant module that forms the vehicle's integrated thermal management module and the refrigerant module of the air conditioner are not modularized with each other, so the piping path of the air conditioner is complicated and requires more piping, which increases the refrigerant flow resistance in the piping, resulting in vibration insulation properties. There was this insufficient problem.

Accordingly, a method has recently been discussed to secure design freedom of the vehicle's integrated heat management module through a modular structure by adding an air conditioner refrigerant module to the coolant module.

The matters described as background technology above are only for the purpose of improving understanding of the background of the present invention, and should not be taken as acknowledgment that they correspond to prior art already known to those skilled in the art.

1 is a diagram showing an integrated refrigerant module and an integrated heat management module of a vehicle according to an embodiment of the present invention.

Referring to Figure 1, base 300; A plurality of refrigerant lines are formed on the base 300 to be spaced apart, through which refrigerant flows, and are formed integrally with the base 300; and a multi-way valve installed at the intersection of the refrigerant lines to control the flow of the refrigerant, wherein the plurality of refrigerant lines are each connected to a compressor or condenser provided outside the base 300 or a heat exchanger of an indoor air conditioning device and an evaporator or chiller (200). ) constitutes an integrated refrigerant module of the vehicle, characterized in that it is connected to at least one of the following.

In the case of the present invention, the refrigerant delivery path is simplified by integrating the refrigerant module into the coolant module of a vehicle in which the conventional PE EWP (Electric Water Pump), battery EWP, PE multi-way valve, battery multi-way valve, and reservoir 100 are integrated. It has the characteristic of improving insulation characteristics.

First, the way the refrigerant module works is that in the compressor, gaseous refrigerant is compressed, creating high-temperature, high-pressure gaseous refrigerant. High-temperature, high-pressure gaseous refrigerant enters the condenser and condenses to become high-pressure liquid refrigerant, and the temperature becomes relatively low (medium temperature). The medium-temperature, high-pressure liquid refrigerant is decompressed through an expansion valve and becomes a low-temperature, low-pressure refrigerant in which liquid and gaseous states coexist. The low-temperature, low-pressure refrigerant absorbs heat as it passes through the evaporator and becomes a medium-temperature, low-pressure refrigerant. The refrigerant that leaves the evaporator goes back into the compressor and repeats the same cycle.

At this time, the refrigerant leaving the evaporator still coexists in liquid and gaseous states, so in order to send only the gaseous refrigerant to the compressor, a gas-liquid separator that can separate the liquid refrigerant and the gaseous refrigerant is needed.

The present invention modularizes vehicle refrigerant-related parts centered on this gas-liquid separator, thereby achieving compactness of multiple parts and reducing production costs by enabling them to be assembled in a package module state during the manufacturing/assembly process. The goal is to obtain.

Meanwhile, the refrigerant leaving the evaporator (medium temperature, low pressure) is at a relatively lower temperature than the refrigerant located before leaving the condenser and entering the expansion valve (medium temperature, high pressure).

Therefore, when heat exchange occurs between the refrigerants in the above two states, the refrigerant located before leaving the condenser and entering the expansion valve can pass through the expansion valve at a lower temperature than before. Accordingly, the refrigerant whose pressure is reduced through the expansion valve becomes a refrigerant at a lower temperature than before, allowing it to absorb more heat as it passes through the evaporator.

Specifically, the base 300, in which a plurality of refrigerant lines are spaced apart and through which refrigerant flows, has a plate-type shape where a front plate and a rear plate are joined, and can be formed by being integrally coupled to a coolant module with a large area.

The base 300, which has a plate-type shape, is easy to assemble, making it easy to form refrigerant lines inside, and a structure in which the front and back plates are combined allows multiple refrigerant lines to be formed in a narrow space. Therefore, when the front and rear plates are combined, a plurality of refrigerant lines are formed between the front and rear plates to ensure sufficient space inside the base 300.

More specifically, half of the refrigerant line is formed on the facing side of the front and back plates, and the refrigerant line is completed when the facing sides of the front and back plates are combined. The front and rear plates constituting the base 300 are joined through an aluminum welded structure or a plastic welded structure to form a structure in which the refrigerant flowing in the internal refrigerant line does not leak and the space excluding the refrigerant line is sealed. Here, the aluminum welded structure or the plastic welded structure of the front and rear plates is an example, and is not necessarily limited thereto, and various welded structures may be included.

Refrigerant lines formed on opposite sides of the front and rear plates are each connected to at least one of a plurality of external components such as a compressor or condenser provided outside the base 300, a heat exchanger of an indoor air conditioning device, an evaporator, or a chiller 200, and the refrigerant It can be discharged or introduced.

Accordingly, the end of the refrigerant line extends to the end of the base 300 and an external component is connected to the end of the refrigerant line, so that a plurality of external components can be interconnected through the refrigerant line. Each refrigerant line can be connected to the chiller 200, a gas-liquid separator, an evaporator, an indoor heat exchanger, and a condenser, and the inside of the refrigerant line includes a cooling expansion valve 310, a heating expansion valve 320, and a first valve ( It may be composed of a multi-way valve including 330) and a second valve 340.

Additionally, the base 300 and the refrigerant line can be molded together from aluminum and plastic materials. Here, the refrigerant line can be molded integrally with the base 300, and it is desirable that the material constituting the base 300 and the refrigerant line be light and durable. Materials of the base 300 and the refrigerant line may include both aluminum brazing and plastic injection, but this is an example and is not necessarily limited thereto.

Meanwhile, a multi-way valve is installed at the intersection of refrigerant lines to control the flow of refrigerant. A multi-way valve can change the flow of refrigerant in four directions at the intersection of refrigerant lines, and multiple valves can be provided. The on-off valve 400 is formed in a line branched to one side from the connection line between the first valve 330 and the second valve 340 and connected to the evaporator inlet, so that the refrigerant that has passed through the first valve 330 goes directly to the evaporator. The inflow into the inlet line can be controlled.

Specifically, in the present invention, the multi-way valve consists of a first valve 330 and a second valve 340, and the first valve 330 and the second valve 340 are spaced apart from each other and connected to the base 300. It is installed at each refrigerant line intersection to control the flow of refrigerant at the intersection.

Referring to FIG. 1, the first valve 330 and the second valve 340 are arranged to be spaced apart from each other at a predetermined interval with the heating expansion valve 320 in between, and the first valve 330 and the second valve 340 ) By changing the refrigerant direction, the vehicle's interior cooling mode, vehicle's electronic component cooling mode, vehicle's interior heating mode, interior heating mode using waste heat, and interior dehumidification heating mode using waste heat can be changed to each other.

At this time, the first valve 330 is installed at the intersection of the compressor outlet line, the inlet and outlet lines of the heat exchanger of the indoor air conditioning system, and the connection line between the first valve 330 and the second valve 340, The second valve 340 may be installed at the intersection of the connection line between the first valve 330 and the second valve 340, the condenser inlet line and outlet line, and the inlet line of the chiller 200.

Figures 2 and 3 are schematic diagrams showing the flow of refrigerant in the vehicle's interior cooling mode, the vehicle's interior cooling mode, and the vehicle's electronic component cooling mode, respectively.

Referring to Figures 2 and 3, when cooling the interior of a vehicle, the refrigerant is discharged from the compressor and flows into the condenser through the first valve 330 and the second valve 340, and the refrigerant discharged from the condenser flows through the second valve ( 340) and flows into the evaporator, and when cooling the vehicle's electronic components, the refrigerant discharged from the condenser passes through the second valve 340 and flows into the chiller 200, thereby allowing cooling.

Specifically, when the refrigerant discharged from the compressor outlet line passes through the first valve 330 and flows into the inlet line of the heat exchanger of the indoor air conditioning device, it heats the interior of the vehicle and the outlet side of the heat exchanger of the indoor air conditioning device. The refrigerant discharged from the line or from the outlet line of the compressor passes through the second valve 340 and enters the condenser and condenses to become a high-pressure liquid refrigerant, and the temperature is relatively lowered. The medium-temperature, high-pressure liquid refrigerant discharged from the condenser is decompressed through the cooling expansion valve 310 and becomes a low-temperature, low-pressure refrigerant in which liquid and gaseous states coexist.

Figures 4 and 5 are schematic diagrams showing the flow of refrigerant in the vehicle's interior heating mode and the vehicle's interior heating mode using waste heat from the battery, respectively.

Referring to Figures 4 and 5, the refrigerant is discharged from the extruder, passes through the heat exchanger of the indoor air conditioning system through the first valve 330, passes through the first valve 330 and the second valve 340, and flows into the condenser, When the refrigerant flows into the evaporator instead of passing through the second valve 340 into the chiller 200, it heats the vehicle interior, and when the refrigerant flows into the chiller 200 after passing through the second valve 340, it passes through the waste heat of the battery and heats the vehicle interior. is heated.

At this time, the line on the inlet side of the chiller 200 connected to the second valve 340 may branch to one side and form a line connected to the inlet side of the evaporator. The low-temperature, low-pressure refrigerant flowing in the line connected to the evaporator inlet absorbs heat as it passes through the evaporator and becomes a medium-temperature, low-pressure refrigerant. The refrigerant that leaves the evaporator passes through the gas-liquid separator again and enters the compressor, repeating the same cycle. .

Figure 6 is a schematic diagram showing the flow of refrigerant in the dehumidifying and heating mode of the vehicle's interior using waste heat from the battery.

Referring to FIG. 6, the connection line between the first valve 330 and the second valve 340 may branch to one side and form a line connected to the inlet side of the evaporator. The refrigerant discharged from the outlet line of the heat exchanger of the indoor air conditioning system flows through a line branched from the connection line between the first valve 330 and the second valve 340 and connected to the evaporator. In this case, the refrigerant that did not pass through the condenser and chiller 200 passes through the evaporator and can dehumidify the room using waste heat generated from the battery and motor.

Meanwhile, an integrated coolant module in which the reservoir 100, chiller 200, and coolant valve are combined into one module; and an integrated coolant module to form one module, and are formed with a base 300, a plurality of which are spaced apart on the base 300, and are installed at the intersection of the refrigerant line and the refrigerant lines formed integrally with the base 300 to cool the coolant. It is composed of a multi-way valve that regulates the flow of, and constitutes an integrated heat management module of the vehicle that includes an integrated refrigerant module in which a plurality of refrigerant lines are each connected to components external to the base 300.

A single integrated heat management module is formed by integrating the previously described integrated refrigerant module and the conventional integrated coolant module, and the modularized structure simplifies the refrigerant transmission path in the air conditioner refrigerant module piping to improve vibration insulation characteristics.

Specifically, the integrated thermal management module of the vehicle is a single thermal management module in which the integrated coolant module and the above-described integrated refrigerant module are assembled, as shown in FIG. 1, and the integrated coolant module and the integrated refrigerant module can be placed and assembled in adjacent positions. The integrated coolant module can manage all distribution/supply of coolant, electrical/driving parts, and batteries. As mentioned above, the integrated refrigerant module is an air conditioner refrigerant module that operates in room heating mode, room heating mode using waste heat, and waste heat utilizing waste heat. Indoor dehumidification and heating modes can be changed.

By integrating the integrated refrigerant module and the integrated coolant module, and configuring the multi-way valve that is installed at the intersection of the refrigerant lines to control the flow of the refrigerant within the base 300 that constitutes the integrated refrigerant module, design freedom can be increased and integrated. The overall size of the thermal management module can be reduced.

In addition, efficient thermal management can be performed by placing the coolant module adjacent to the refrigerant module. Through efficient thermal management, the vehicle's driving distance is increased and battery life is also improved.

Looking at the structure of the vehicle's integrated heat management module, the base 300 is formed in a plate-type shape as shown in Figure 1, one side of the base 300 is coupled to face one side of the chiller 200, and the chiller 200 ) The reservoir 100 may be coupled to face the other side. The base 300 constituting the integrated refrigerant module is formed as a flat plate type. In this case, one side of the base 300 can be coupled to face one side of the chiller 200, where the position of the base 300 is is illustrative and is not necessarily limited thereto.

It is obvious to those skilled in the art that various modifications are possible, such as, for example, the base 300 and the reservoir 100 may be located simultaneously on one side of the chiller 200 depending on the layout of the integrated heat management module.

Figure 7 is an exploded perspective view of an integrated thermal management module of a vehicle according to an embodiment of the present invention. The integrated thermal management module of a vehicle according to the present invention has a plurality of valve spaces and a plurality of coolant channels 510 in communication with the valve spaces. ) Multi-channel 500 formed around the valve space; It consists of a plurality of valve bodies, each of which is inserted into the valve space, and opens and closes the coolant channel 510 around the valve space of the multi-channel 500 when operated. and a plurality of pumps 600 coupled to the multi-channel 500, wherein the valve space is formed on one side of the multi-channel 500 and the valve body 700 is coupled to one side of the multi-channel 500. The pump 600 is coupled to the other side of the multi-channel 500, and the rotation axis of the valve body 700 and the rotation axis of the pump 600 may coincide.

Referring to FIG. 7, the integrated thermal management module of the present invention has a valve body 700 coupled to one side with a multi-channel 500 in between, and a pump 600 coupled to the other side. At this time, since the valve body 700 and the pump 600 are coupled so that their rotation axes match each other, compact design of the module is possible, and there is an advantage of having the most effective layout that is advantageous to the mold structure. Here, a plurality of valve spaces formed on one side of the multi-channel 500 are protruding, and the valve body 700 is inserted into each valve space, and a plurality of pump spaces are protruded on the other side, so that a pump is installed in each pump space. By inserting it, a stable coupling structure can be formed on both sides of the multi-channel 500.

In addition, the vehicle's integrated thermal management module is coupled to the multi-channel 500, and the interior is divided into a plurality of storage spaces, and each storage space is connected to each coolant channel 510 of the multi-channel 500. ); and the multi-channel 500, wherein the coolant and the refrigerant exchange heat, and the internal coolant passage 420 is divided into a plurality of spaces, and the space of each coolant passage is connected to the multi-channel through the coolant inlet 430. It may further include a chiller 200 connected to the valve space of 500.

Describing the configuration of the present invention in detail, a plurality of valve spaces into which the valve body 700 is inserted are formed inside the multi-channel 500, and a plurality of coolant channels 510 in communication with the valve space are formed in the valve space. It is formed around. The valve body 700 rotates in the valve space by a driving unit such as the actuator 800, and controls the flow and direction of coolant within the multi-channel 500. That is, the coolant channel 510 in communication with the valve space is opened and closed by rotation of the valve body 700, so that coolant may or may not flow into the coolant channel 510. Meanwhile, the reservoir 100 serves to store coolant. Referring to FIG. 7, the reservoir 100 is coupled to the multi-channel 500, and the reservoir 100 may be divided into a plurality of storage spaces by a partition 240 formed therein. Accordingly, coolant in different storage spaces can be stored without mixing with each other. In addition, each storage space inside the reservoir 100 is connected to each coolant channel 510 of the multi-channel 500, so that the reservoir 100 is connected to the multi-channel according to the movement of the valve body 700 within the multi-channel 500. Cooling water can be supplied to (500).

The chiller 200 is formed with a coolant flow path 420 and a refrigerant flow path inside. Referring to FIG. 9, the interior of the coolant passage 420 is divided into a plurality of spaces by a partition wall 450, so the coolant that cools the battery (B) and the coolant that cools the electrical components (E) do not mix with each other. . Additionally, a cooling water inlet 430 is formed on the side of the chiller 200, and the cooling water inlet 430 is connected to the multi-channel 500. The pump 600 is coupled to the multi-channel 500 and serves to pressurize coolant. The pump 600 is composed of a plurality of pumps to equal the number of coolant passage compartment spaces of the reservoir 100 and the chiller 200, and each is coupled to the multi-channel 500.

Meanwhile, referring to FIG. 8, the chiller 200 is provided with a plurality of coolant inlets 430, and the coolant inlets 430 include a coolant inlet 435, a radiator inlet 437, and a coolant outlet 436. may be located above the coolant inlet 435.

Specifically, inside the chiller 200, the first coolant and the second coolant flow through the first coolant passage 421 and the second coolant passage 422, respectively, so that each coolant inlet supplies the first coolant and the second coolant. 435 is required, and likewise each coolant outlet 436 is required. At this time, the coolant outlet 436 is preferably located above the coolant inlet 435, because coolant cooled in a natural flow manner can be supplied to the multi-channel 500 through the coolant outlet.

Meanwhile, the multi-channel 500 and the reservoir 100 may be made of different materials. Conventionally, components such as the chiller 200 and the pump 600 are combined around the reservoir 100, so the reservoir 100 Since it is inevitably made of a heavy and hard hard material like the multi-channel 500, there is a problem that the weight of the heat management module increases and the driving distance of the vehicle is relatively shortened accordingly. When components are combined around the multi-channel 500 as in the present invention, in particular, the reservoir 100, which only performs the coolant storage function, does not need to be made of a hard material like the multi-channel 500, and is used according to the weight of the coolant. Since it is sufficient to be made of a soft material that can withstand the load, the weight of the reservoir 100 can be reduced compared to before, and thus the weight of the vehicle can be reduced to increase the driving distance and thus increase battery efficiency.

In addition, looking at the arrangement structure of the vehicle's integrated heat management module, a reservoir 100 and a base 300 are located on both sides centered on the chiller 200, a water pump is located below the reservoir 100, and the base 300 ) By locating the compressor below, the refrigerant delivery path in the air conditioner refrigerant module piping can be simplified. The positions of the water pump and compressor are exemplary and are not necessarily limited thereto, and it is obvious to those skilled in the art that all positions for simplifying the refrigerant delivery path in the air conditioner refrigerant module piping are included. In addition, the integrated coolant module is configured so that the top of the reservoir is placed the highest among the reservoir 100, chiller 200, and coolant valve, so that the gas collected at the top of the reservoir 100 can be easily discharged.

Ultimately, according to the integrated refrigerant module and integrated heat management module of the vehicle of the present invention, the refrigerant transfer path is simplified in the air conditioner refrigerant module piping through a modular structure by adding the air conditioner refrigerant module to the coolant module, thereby improving vibration insulation characteristics and improving the vibration insulation characteristics of the pipe side muffler. By reducing the number of parts, it is possible to secure competitiveness in terms of cost and weight.
