Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to and the benefit of Korean Patent Application No. 10-2023-0120237 filed in the Korean Intellectual Property Office on September 11, 2023, the entire contents of which are incorporated herein by reference. Technical Field

[0003] The present disclosure relates to a refrigerant valve module for a vehicle. More particularly, the present disclosure relates to a refrigerant valve module for a vehicle capable of integrally forming a plurality of valve assemblies and a valve manifold. Background Art

[0004] Generally, an air conditioning system for a vehicle includes an air conditioning unit that circulates a refrigerant to heat or cool the interior of the vehicle.

[0005] The air conditioning unit is used to keep the interior of the vehicle at an appropriate temperature regardless of changes in the outside temperature to maintain a comfortable interior environment. In particular, the air conditioning unit is configured to heat or cool the interior of the vehicle by circulating the refrigerant discharged from the compressor while exchanging heat in the condenser and the evaporator. In this process, the refrigerant discharged by the drive of the compressor passes through the condenser, the receiver-drier, the expansion valve, and the evaporator, and the refrigerant circulates back to the compressor.

[0006] In other words, in cooling mode, the air conditioning unit reduces the temperature and humidity of the interior of the vehicle by condensing high-temperature and high-pressure gas-phase refrigerant compressed from the compressor by the condenser, passing the refrigerant through the receiver-drier and the expansion valve, and then evaporating the refrigerant in the evaporator.

[0007] In view of the increasing concern about energy efficiency and environmental pollution, it is expected to develop an environmentally friendly vehicle that can basically replace internal combustion engine vehicles. Environmentally friendly vehicles are divided into electric vehicles driven by using fuel cells or electricity as a power source and hybrid vehicles driven by using an engine and a battery.

[0008] Unlike air conditioners of general vehicles, in electric vehicles or hybrid vehicles among these environmentally friendly vehicles, a separate heater is not used, and the air conditioners used in the environmentally friendly vehicles are generally called heat pump systems.

[0009] Electric vehicles driven by fuel cells as a power source generate driving force by converting the chemical reaction energy between oxygen and hydrogen into electrical energy. In this process, the chemical reaction in the fuel cell generates heat energy. Therefore, it is necessary to effectively remove the generated heat energy to ensure the performance of the fuel cell.

[0010] In addition, in hybrid vehicles, driving force is generated by driving a motor using electricity supplied from a fuel cell or a battery and operating an engine using ordinary fuel. Therefore, it is necessary to effectively remove heat generated from the fuel cell, battery and motor to ensure the performance of the motor.

[0011] Therefore, in a hybrid vehicle or an electric vehicle according to the related art, a cooling device for preventing heat generation in a motor and electric components and a battery cooling device for preventing heat generation in a battery including a fuel cell should be configured with separate sealed circuits.

[0012] Therefore, there are disadvantages in that the size and weight of the cooling module provided at the front of the vehicle increase, and the layout of connection pipes for supplying refrigerant or coolant to each heat pump system, a cooling device in the engine room, and a battery cooling device is complicated.

[0013] The above information disclosed in this Background section is provided only to enhance understanding of the background of the present disclosure and therefore may contain information that does not constitute the prior art. Summary of the invention

[0019] The plurality of refrigerant holes may include a first refrigerant hole, a second refrigerant hole, a third refrigerant hole, a fourth refrigerant hole, and a fifth refrigerant hole. In particular, the first refrigerant hole is configured to be connected to the first mounting groove through the first fluid pipeline, and is horizontally formed toward the second body based on the length direction of the valve manifold. The second refrigerant hole is configured to be connected to the first mounting groove through the first fluid pipeline, and is horizontally formed toward the third body based on the length direction of the valve manifold. The third refrigerant hole connected to the first mounting groove through the first fluid pipeline can be formed perpendicular to the first refrigerant hole and the second refrigerant hole in the opposite direction of the first mounting groove. The fourth refrigerant hole connected to the second mounting groove through the second fluid pipeline can be formed perpendicular to the first refrigerant hole in the second body, and the fifth refrigerant hole formed in the second body and arranged on the same axis as the fourth refrigerant hole is configured to be connected to the second mounting groove through the second fluid pipeline.

[0020] The plurality of refrigerant holes may further include: a sixth refrigerant hole, which is connected to the third mounting groove through the third fluid pipeline and is formed in the third body perpendicular to the second refrigerant hole.

The valve assembly may further include: a ball coupled to a second end of the shaft and rotated by the power of the actuator; and a valve seat housing coupled to the actuator and configured to rotatably accommodate the ball.

[0025] The valve seat housing may gradually decrease in diameter from the actuator toward the valve manifold.

[0026] The ball may include an inlet passage selectively communicating with the refrigerant fluid line and configured to receive the refrigerant; and an outlet passage communicating with the inlet passage and configured to discharge the refrigerant introduced into the inlet passage.

[0103] In addition, the refrigerant supplied to the valve manifold 100 may selectively flow into the eighth refrigerant hole 168 or the ninth refrigerant hole 169 .

[0104] The refrigerant introduced into the valve manifold 100 through the eighth refrigerant hole 168 or the ninth refrigerant hole 169 may flow along the refrigerant fluid line 102 .

[0106] In addition, the valve assembly 300 may be provided in plural numbers. The valve assembly 300 may be installed on the valve manifold 100 to control the flow of the refrigerant flowing in the refrigerant fluid line 102 .

[0107] In this embodiment, three valve assemblies 300 may be provided, which are respectively installed in the first installation groove 112 of the first body 110 , the second installation groove 122 of the second body 120 , and the third installation groove 132 of the third body 130 .

[0108] Here, if Figures 9 to 11 As shown, the valve assembly 300 may include an actuator 310 , a shaft 320 , a ball 330 , and a valve seat housing 340 .

[0109] First, the actuator 310 generates torque. The actuator 310 may include a connector 312 at one side thereof to connect a signal line and / or a power line of the actuator 310.

[0110] In the present embodiment, a first end of the shaft 320 may be coupled to the actuator 310 to receive power from the actuator 310 .

[0111] In other words, the actuator 310 may rotate the shaft 320 in a forward direction or a reverse direction according to a control signal transmitted to the actuator 310 and power supplied to the actuator 310 .

[0112] In the present embodiment, the ball 330 may be coupled to the second end of the shaft 320. When the shaft 320 is rotated by the rotational power of the actuator 310, the ball 330 may be rotated in the same direction as the shaft 320.

[0113] Here, the ball 330 may include an inlet channel 332 and an outlet channel 334 .

[0114] The inlet passage 332 may selectively communicate with the refrigerant fluid line 102. Refrigerant may flow into the inlet passage 332.

[0115] The outlet channel 334 may communicate with the inlet channel 332. The refrigerant introduced into the inlet channel 332 may be discharged to the outlet channel 334.

[0116] In other words, the refrigerant introduced into the valve manifold 100 through the eighth refrigerant hole 168 or the ninth refrigerant hole 169 may be discharged to the outlet channel 334 via the inlet channel 332 .

[0117] In more detail, when the ball 330 rotates in a forward direction or a reverse direction through the operation of the actuator 310, the refrigerant can be discharged through the outlet channel 334 through one or more refrigerant holes among the third refrigerant hole 163, the fourth refrigerant hole 164, the fifth refrigerant hole 165, the sixth refrigerant hole 166 or the seventh refrigerant hole 167.

[0118] In addition, the valve seat housing 340 may rotatably accommodate the ball 330. The valve seat housing 340 may be coupled to the actuator 310.

[0119] Here, the diameter of the valve seat housing 340 may be formed to gradually decrease from the actuator 310 toward the valve manifold 100 .

[0120] Therefore, when the valve assembly 300 is mounted on the first mounting groove 112 , the second mounting groove 122 , or the third mounting groove 132 , the valve seat housing 340 may be smoothly inserted into the first mounting groove 112 , the second mounting groove 122 , or the third mounting groove 132 .

[0121] In another embodiment, a sealing member 400 may be interposed between the valve manifold 100 and the valve assembly 300 .

[0122] The sealing member 400 can prevent the refrigerant from leaking between the valve manifold 100 and the valve assembly 300 .

[0123] like Fig. 9 As shown, in the ball 330 in the valve assembly 300 mounted on the third mounting groove 132 , two outlet channels 334 communicating with the inlet channel 332 may be formed at both sides of the inlet channel 332 .

[0124] Therefore, if the refrigerant valve module 10 for a vehicle according to the embodiment of the present disclosure is applied as described above, the refrigerant valve module 10 integrally forms a plurality of valve assemblies 300 by using the valve manifold 100 , is simple to assemble due to a reduced number of components, and is easy to maintain.

[0125] In addition, according to the present disclosure, by using the valve manifold 100 to mount the plurality of valve assemblies 300 and including the refrigerant flow path 102 inside, refrigerant leakage may be prevented while minimizing the sealing member 400, thereby improving overall marketability.

[0126] In addition, according to the present disclosure, since the refrigerant flow path 102 formed in the valve manifold 100 has no sharp bends, channel resistance may be reduced and use of connection pipes may be minimized.

[0127] Furthermore, according to the present disclosure, by promoting simplification and modularization of components, manufacturing costs can be reduced and weight can be reduced, and space utilization can be improved.

[0128] While the present disclosure has been described in conjunction with what are presently considered to be practical embodiments, it will be understood that the present disclosure is not limited to the disclosed embodiments. On the contrary, the present disclosure is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
