Description

TECHNICAL FIELD

[0001] The present invention relates to a manifold fluid module, and more particularly, to a manifold fluid module in which components of a heat exchanger and a valve are modularized into one unit.BACKGROUND ART

[0002] Under the trend of environmentally friendly industrial development and development of energy sources that replace fossil fuels, electric vehicles and hybrid vehicles are fields that attract the most attention in a vehicle industry in recent years. The electric vehicles and the hybrid vehicles are equipped with batteries to provide driving power, and the batteries are used not only for driving but also for cooling and heating.

[0003] In vehicles that receive driving forces using the batteries, the fact that the batteries are used as heat sources during the cooling and heating means that a drivable distance is decreased due to the use of the heat sources. A method of applying a heat pump system, which is widely used as the conventional household cooling and heating device, to the vehicles has been proposed in order to overcome the above problem.

[0004] For reference, a heat pump refers to a component that absorbs low-temperature heat and moves the absorbed heat to a high temperature. As an example, the heat pump has a cycle in which a liquid fluid is evaporated in an evaporator, takes heat from the surroundings, is converted into gas, and is liquefied back while emitting heat to the surroundings through a condenser. When this is applied to electric vehicles or hybrid vehicles, there is an advantage in that a heat source that is insufficient for a general air conditioner according to the related art may be secured.

[0005] Currently, a module of a heat management system for an electric vehicle is formed by connecting main components (e.g., a valve, an accumulator, a chiller, a condenser, an internal heat exchanger, and a sensor) by pipes in a partial modulization method. In a process of modularizing a vehicle heat management system, relatively many valves among the components are required, and it is necessary to develop a manifold fluid module for properly mounting the valves on a manifold plate.DISCLOSURETechnical Problem

[0006] The present invention is directed to providing a manifold fluid module in which a package is optimized and a volume of a manifold plate is reduced by as much as a volume of a valve body because a valve seating part formed integrally with a manifold plate is substantially formed to serve as the valve body.

[0007] The present invention is also directed to providing a manifold fluid module of which airtightness is maintained because a valve mounted on a manifold plate does not interfere with a fluid passage formed on a manifold.

[0008] The present invention is also directed to providing a manifold fluid module capable of fundamentally preventing heat transfer through a passage formed on a manifold plate and improving performance of a heat management system because a fluid directly flows from a compressor to a heat exchanger without passing through a separate passage on the manifold plate.Technical Solution

[0009] One aspect of the present invention provides a manifold fluid module including a manifold plate in which a fluid passage is formed on one surface thereof, the fluid passage being formed along one passage stage, a valve seating part formed at an upper stage than the passage stage on the one surface of the manifold plate and having an inlet slot through which a fluid is introduced, and a valve that is coupled to the valve seating part and expands the fluid or controls a flow direction of the fluid, wherein an inflow space is formed between the valve seating part and the valve so that the fluid passing through the inlet slot is introduced into the valve.

[0010] At least a portion of the inflow space may be formed in a circumferential direction of the valve.

[0011] The inflow space may have a ring-shaped cross section surrounding the valve.

[0012] At least a portion of the inlet slot may be formed in a circumferential direction of the valve.

[0013] The inlet slot may have a semi-ring-shaped cross section surrounding the valve.

[0014] The inlet slot may be formed at one side of the valve seating part, and an outlet hole through which the fluid introduced into the valve is discharged may be formed in a bottom surface of the valve seating part.

[0015] The valve may be a needle-type expansion valve that expands the fluid introduced into a heat exchanger.

[0016] The valve may include a first expansion valve and a second expansion valve that expand an introduced high-temperature and high-pressure fluid, and the fluid passage may include a first branch passage through which the fluid is introduced into the first expansion valve and a second branch passage which branches off from the first branch passage and through which a refrigerant is introduced into the second expansion valve, and a flow of the fluid may be controlled by opening or closing the first expansion valve and the second expansion valve or adjusting opening amounts of the first expansion valve and the second expansion valve according to an air conditioning mode.

[0017] The manifold fluid module may further include a compressor coupled to the manifold plate and a first heat exchanger which is coupled to the manifold plate, is connected so that a first fluid discharged from the compressor is directly introduced, and exchanges heat between the first fluid and a second fluid, wherein the compressor may be coupled to one surface of the manifold plate, and the first heat exchanger may be coupled to the other surface of the manifold plate, and the compressor may have a first fluid inflow port and a first fluid outflow port, the first heat exchanger may have a first fluid inflow port and a first fluid outflow port, and any one of the first fluid inflow port and the first fluid outflow port of the compressor may be directly connected to and communicate with any one of the first fluid inflow port and the first fluid outflow port of the first heat exchanger.

[0018] The first fluid outflow port of the compressor may be directly connected to and communicate with the first fluid inflow port of the first heat exchanger.

[0019] The first fluid inflow port of the compressor may be coupled to the one surface of the manifold plate, and the first fluid outflow port of the first heat exchanger may be coupled to the other surface of the manifold plate.Advantageous Effects

[0020] According to an embodiment of the present invention, since a valve seating part formed integrally with a manifold plate is substantially formed to serve as a valve body, a package can be optimized, and a volume of a manifold plate can be reduced by as much as a volume of a valve body.

[0021] Further, according to the embodiment of the present invention, since a valve mounted on a manifold plate does not interfere with a fluid passage formed on a manifold, airtightness of the manifold fluid module can be maintained.

[0022] Further, according to the embodiment of the present invention, since a fluid directly flows from a compressor to a heat exchanger without passing through a separate passage on a manifold plate, heat transfer through a passage formed on the manifold plate can be fundamentally prevented, and performance of a heat management system can be improved.DESCRIPTION OF DRAWINGS

[0039] According to the illustration, a manifold fluid module according to the embodiment of the present invention may include a manifold plate 1 in which a fluid passage 22 is formed, valve seating parts 20 and 30 which are formed in the manifold plate 1 and in which inlet slots 24 and 34 through which a fluid flows are formed, and a valve that is coupled to the valve seating parts 20 and 30 and expands the fluid or controls a flow direction of the fluid, wherein an inflow space 25 may be formed between the valve seating parts 20 and 30 and the valve so that the fluid passing through the inlet slots 24 and 34 may flow into the valve.

[0040] A bottom plate 2 may be coupled to one surface of the manifold plate 1 to cover a passage and may be manufactured in a manner of coupling using brazing, a structural adhesive, a gasket, or the like. Further, various materials such as aluminum, thermoplastic, and stainless steel may be applied to a material of the manifold plate 1 depending on a purpose and function and depending on a manufacturing method. The bottom plate 2 may be installed on a mounting frame 4 having a structure mounted on a vehicle.

[0041] The manifold plate 1 is formed such that a fluid passage is roughly recessed therein and has a plate shape having a predetermined thickness. In this way, a first heat exchanger 40, a second heat exchanger 60, a third heat exchanger 80, an accumulator 50, and expansion valves 70 and 90 that are heat exchange devices of the heat management system are coupled and modularized on the manifold plate 1, thus product manufacturing labor can be reduced, and vehicle assembly line labor may also be reduced. Further, since the manifold plate 1 simultaneously performs functions of piping, fitting, and housing, costs can be reduced, and workability can be improved.

[0042] The manifold plate 1 may have openings 6 that are open in a front-rear direction. The opening 6 is a portion formed such that a high-temperature area and a low-temperature area of the passage of the manifold plate 1 are spaced apart from each other as much as possible and also serves to prevent interference with a fluid port of a heat exchanger. The opening 6 may be formed adjacent to a passage of a fluid introduced into a compressor 110 to avoid thermal interference.

[0043] Referring to FIG. 2, a fluid passage that guides movement of the fluid in heat exchange, expansion, inflow and outflow may be formed on a rear surface of the manifold plate 1. Further, various fluid ports for the inflow and the outflow of the fluid may be provided in the rear surface of the manifold plate 1. In an embodiment, the fluid ports may include a first heat exchanger outflow port 8 through which the fluid is discharged of the first heat exchanger 40, an accumulator inflow port 10 and an accumulator outflow port 12 through which the fluid flows in or from the accumulator 50, a second heat exchanger inflow port 13 and a second heat exchanger outflow port 14 through which the fluid flows in or from the second heat exchanger 60, and a third heat exchanger inflow port 17 and a third heat exchanger outflow port 18 through which a first fluid flows in or from the third heat exchanger 80.

[0044] The compressor 110 is coupled to the other surface, i.e., the rear surface, of the manifold plate 1. The compressor 110 serves to compress the first fluid at a high temperature and a high pressure and move the compressed first fluid to the first heat exchanger 40. Further, the first heat exchanger 40, the second heat exchanger 60, and the third heat exchanger 80, as heat exchanging devices, are coupled to one surface, i.e., a front surface, of the manifold plate 1. In the first heat exchanger 40, the second heat exchanger 60, and the third heat exchanger 80, the first fluid and a second fluid may be heat-exchanged while passing therethrough.

[0045] In the present embodiment, a water-cooled condenser may be used as the first heat exchanger 40, a water-cooled evaporator may be used as the second heat exchanger 60, and a chiller may be used as the third heat exchanger 80. The water-cooled condenser serves to condense a high-pressure liquid by heat-exchanging a high-temperature and high-pressure gaseous fluid (a refrigerant) discharged a compressor or an internal condenser with an external heat source. The water-cooled evaporator serves to evaporate the expanded first fluid (a refrigerant) by heat-exchanging the expanded first fluid with the second fluid (a coolant) and cool the second fluid. The second fluid heat-exchanged in the water-cooled condenser may perform heating on an interior of the vehicle, and the second fluid heat-exchanged in the water-cooled evaporator may perform cooling on the interior of the vehicle. The chiller is a device in which the low-temperature and low-pressure first fluid is supplied and heat-exchanged with the second fluid (a coolant) moving in a coolant circulation line (not illustrated), and the cold second fluid heat-exchanged in the chiller may be heat-exchanged with a battery while circulating through the coolant circulation line.

[0046] Meanwhile, a refrigerant, a coolant, and the like may be applied as the first fluid and the second fluid, and in the present embodiment, the refrigerant may be applied as the first fluid and the coolant may be applied as the second fluid.

[0047] The first heat exchanger 40 is connected to the compressor 110 so that the fluid may directly move. In more detail, a first fluid inflow port 41 through which the first fluid flows from the first heat exchanger 40 may be directly connected to a port through which the first fluid flows from the compressor 110, and thus the first fluid may be directly introduced without passing through a passage on the manifold plate 1. In other words, while moving from the compressor 110 to the first heat exchanger 40, the first fluid may move through a passage in direct connection without passing through the manifold plate 1.

[0048] In this way, when the fluid does not pass through a separate passage on the manifold plate 1 in the compressor 110, the high-temperature and high-pressure first fluid (having the highest temperature and the highest pressure in the heat management system) compressed by the compressor 110 may be fundamentally prevented from transferring heat through the manifold plate 1, and thus performance of the heat management system can be improved. As illustrated in FIG. 1, each of the compressor 110 and the first heat exchanger 40 is coupled to the manifold plate 1 but are not coupled through the manifold plate 1 and are partially coupled to allow the first fluid to be directly introduced.

[0049] In more detail, the compressor 110 has a first fluid inflow port 112 and a first fluid outflow port 114, and the first heat exchanger 40 has the first fluid inflow port 41 and a first fluid outflow port 42. Any one of the first fluid inflow port 112 and the first fluid outflow port 114 of the compressor 110 may be directly connected to and communicated with any one of the first fluid inflow port 41 and the first fluid outflow port 42 of the first heat exchanger 40.

[0050] In the drawing, the first fluid outflow port 114 of the compressor 110 is directly connected to and communicated with the first fluid inflow port 112 of the first heat exchanger 40. Further, the first fluid inflow port 112 of the compressor 110 may be connected to one surface of the manifold plate 1, and the first fluid outflow port 42 of the first heat exchanger 40 may be connected to the other side of the manifold plate 1.

[0051] The first heat exchanger 40 may be disposed at one side, i.e., a left end or a right end, of the manifold plate 1, and the accumulator 50, the second heat exchanger 60, and the third heat exchanger 80 may be sequentially arranged on the other side thereof. In this way, the components required for the fluid flow may be sequentially arranged and thus may be integrated and modularized in a limited space of the manifold plate 1.

[0052] Further, the first expansion valve 70 and the second expansion valve 90 are arranged above the second heat exchanger 60 and the third heat exchanger 80, respectively. The first expansion valve 70 and the second expansion valve 90 serve to expand the first fluid introduced into the second heat exchanger 60 and the third heat exchanger 80.

[0053] The accumulator 50 serves to separate the first fluid passing through the second heat exchanger 60 into a gaseous fluid and a liquid fluid. In the present embodiment, a separate heat exchanger is provided in the accumulator 50 to allow the first fluid passing through the first heat exchanger 40 to flow into the second heat exchanger 60 and the third heat exchanger 80 after heat exchange.

[0054] Referring to FIGS. 4 to 9, the first valve seating part 20 and the second valve seating part 30 are formed at an upper stage than a passage stage of the fluid passage 22, through which the first fluid flows, on one surface of the manifold plate 1. Here, the first valve seating part 20 and the second valve seating part 30 may be arranged at a different stage from the passage stage of the fluid passage 22 and are not necessarily arranged at the upper stage. The first expansion valve 70 and the second expansion valve 90 may be seated on and coupled to the first valve seating part 20 and the second valve seating part 30. In the present embodiment, examples of the first expansion valve 70 and the second expansion valve 90 are described, but the present invention is not limited thereto, and any valve may be applied as long as the valve may be coupled to the first valve seating part 20 and the second valve seating part 30.

[0055] The first valve seating part 20 and the second valve seating part 30 may be formed at the upper stage than the passage stage at which the fluid passage 22 is formed. That is, the fluid passage 22 may be formed at a first stage on one surface of the manifold plate 1, the first valve seating part 20 and the second valve seating part 30 may be formed at a second stage, and thus the fluid passage 22 may be arranged to not interfere with the first expansion valve 70, and the second expansion valve 90. In this way, when the first expansion valve 70 and the second expansion valve 90 are arranged at the upper stage, the fluid passage 22 is independently formed at one passage stage, and thus airtightness of the manifold plate 1 can be maintained.

[0056] In the present embodiment, the first valve seating part 20 and the second valve seating part 30 may be formed to substantially serve as a body of the valve. That is, insides of the first valve seating part 20 and the second valve seating part 30 may be formed in a hollow shape, the first expansion valve 70 and the second expansion valve 90 may be coupled thereto and thus serve as the body of the valve, and thus a package can be optimized. Further, the first valve seating part 20 and the second valve seating part 30 are integrally formed in the manifold plate 1, and thus a volume of the manifold plate 1 can be reduced by a volume of the body of the first expansion valve 70 and the second expansion valve 90.

[0057] Since the first valve seating part 20 and the second valve seating part 30 and the first expansion valve 70 and the second expansion valve 90 have substantially the same shape, the first valve seating part 20 and the first expansion valve 70 will be described below as an example.

[0058] An inside of the first valve seating part 20 may be formed in an approximately cylindrical shape to correspond to the shape of the first expansion valve 70. In the present embodiment, a bodyless cartridge-type needle valve may be used as the first expansion valve 70. A first inlet slot 24 through which the refrigerant flows is formed at one side of the first valve seating part 20, and a first outlet hole 26 is formed at a lower stage through which the refrigerant is discharged. Further, a second inlet slot 34 through which the refrigerant flows is formed at one side of the second valve seating part 30, and a second outlet hole 36 is formed at a lower stage through which the refrigerant is discharged.

[0059] As illustrated in FIG. 7, at least a portion of the first inlet slot 24 through which the refrigerant flows may be formed in a circumferential direction of the first expansion valve 70 and, for example, may have a half-ring-shaped cross-section. That is, since the first inlet slot 24 having a half-ring-shaped cross section is formed in the first valve seating part 20, the refrigerant may smoothly flow therein. Of course, as described above, the first inlet slot 24 may be formed at a predetermined central angle with respect to a center of the first expansion valve 70.

[0060] Meanwhile, an inflow space 25 may be formed between the first valve seating part 20 and the first expansion valve 70 so that the refrigerant passing through the first inlet slot 24 may flow into the first expansion valve 70. At least a portion of the inflow space 25 may be formed in the circumferential direction of the first expansion valve 70, and for example, may have a ring-shaped cross section surrounding the first expansion valve 70.

[0061] In this way, when the inflow space 25 is formed, all the introduced refrigerant may smoothly flow through a valve hole 74 formed around a needle 72 of the first expansion valve 70. The valve hole 74 may be formed around the needle 72 at regular intervals in the circumferential direction. When the inflow space 25 is not formed, since the refrigerant flowing in one side of the first expansion valve 70 flows through only a portion of the valve hole 74, and thus smooth inflow may be difficult. However, in the present embodiment, since the inflow space 25 is formed therebetween, the refrigerant may smoothly flow through the valve hole 74 without delay.

[0062] The high-temperature and high-pressure refrigerant introduced into the first expansion valve 70 is changed into a low-temperature and low-pressure refrigerant after expansion and then discharged through the first outlet hole 26 formed at a lower stage. The refrigerant discharged through the first outlet hole 26 is introduced into the fluid passage 22 disposed at a lower stage with respect to the first expansion valve 70.

[0063] As described above, since the needle-type first expansion valve 70 and the needle-type second expansion valve 90 are mounted on the manifold plate 1 in a bodyless manner, the manifold fluid module can be packaged, workability of a product can be increased, and costs can be reduced. Further, since the first expansion valve 70 and the second expansion valve 90 mounted on the manifold plate 1 do not interfere with the fluid passage 22 formed in the manifold plate 1, airtightness of the manifold fluid module can be maintained.

[0064] FIGS. 10 to 12 are views illustrating fluid flows according to opening or closing of the first expansion valve and a second expansion valve according to the embodiment of the present invention.

[0065] In the present embodiment, the plurality of expansion valves 70 and 90 are used, and the flow of the refrigerant may be controlled by opening or closing the expansion valves 70 and 90 or adjusting opening amounts of the expansion valves 70 and 90 according to an air conditioning mode. A refrigerant passage 100 may include a first branch passage 102 through which the refrigerant is introduced into the first expansion valve 70 and a second branch passage 104 which branches off from the first branch passage 102 and through which the refrigerant is introduced into the second expansion valve 90. Further, the refrigerant passage 100 may include a first outflow passage 106 through which the refrigerant is discharged from the first expansion valve 70 and a second outflow passage 108 through which the refrigerant is discharged from the second expansion valve 90.

[0066] Referring to FIG. 10, when both the first expansion valve 70 and the second expansion valve 90 are open, the refrigerant may flow along the first branch passage 102 and the second branch passage 104 and may flow into the first expansion valve 70 and the second expansion valve 90. Further, the refrigerant may be expanded in the first expansion valve 70 and the second expansion valve 90 and then flow out along the first outflow passage 106 and the second outflow passage 108. In this case, flow rates of both passages may be changed according to a degree of opening of the first expansion valve 70 and the second expansion valve 90.

[0067] Referring to FIG. 11, when the second expansion valve 90 is closed, the refrigerant may flow only along the first branch passage 102 and may flow into the first expansion valve 70. Further, the refrigerant may be expanded in the first expansion valve 70 and then may flow out along the first outflow passage 106. In this case, a flow rate of the passage may be changed according to the degree of opening of the first expansion valve 70.

[0068] Referring to FIG. 12, when the first expansion valve 70 is closed, the refrigerant may flow only along the second branch passage 104 and may flow into the second expansion valve 90. Further, the refrigerant may be expanded in the second expansion valve 90 and then may flow out along the second outflow passage 108. In this case, a flow rate of the passage may be changed according to the degree of opening of the second expansion valve 90.

[0069] Although the specific embodiments of the present disclosure have been described above, those skilled in the art may understand that the present disclosure may be variously modified and changed without departing from the spirit and scope of the present disclosure described in the appended claims.[Description of reference numerals]1: Manifold plate2: Bottom plate4: Mounting frame6: Opening8: First heat exchanger outflow port10: Accumulator inflow port12: Accumulator outflow port13: Second heat exchanger inflow port14: Second heat exchanger outflow port16: First expansion valve port17: Third heat exchanger inflow port18: Third heat exchanger outflow port20: First valve seating part22: Fluid passage24: First inlet slot25: Inflow space26: First outlet hole30: Second valve seating part34: Second inlet slot36: Second outlet hole40: First heat exchanger41: First fluid inflow port42: First fluid outflow port43: Second fluid inflow port44: Second fluid outflow port50: Accumulator60: Second heat exchanger70: First expansion valve72: Needle74: Valve hole80: Third heat exchanger90: Second expansion valve100: Refrigerant passage102: First branch passage104: Second branch passage106: First outflow passage108: Second outflow passage110: Compressor112: First fluid inflow port114: First fluid outflow port
