Technical Field

[0003] This invention relates to a water supply module and an electrical equipment cooling system including the water supply module. Background Technology

[0004] Recently, due to energy efficiency and environmental pollution issues, there is a need to develop environmentally friendly vehicles that can largely replace internal combustion engine vehicles.

[0005] Environmentally friendly vehicles are mainly categorized into electric vehicles or hydrogen fuel cell vehicles that use batteries or fuel cells as energy sources, and hybrid vehicles that use both engines and batteries. Such environmentally friendly vehicles include not only engine cooling systems that manage engine cooling and heating, but also electrical equipment cooling systems that manage the heat from electrical components, including the electric motor.

[0006] Electrical equipment cooling systems primarily use coolant to cool power electronic devices, actuators, hybrid starter generators (HSGs), etc., and have a structure that raises the battery temperature in cold seasons by allowing the coolant to bypass the radiator via a bypass circuit and simultaneously allowing waste heat from the power electronic devices (PEs) to pass through the battery.

[0007] However, the electrical equipment cooling system of an environmentally friendly vehicle should meet various purposes from multiple water supply module components, such as heating, cooling, and waste heat recovery. The problem is that due to the limited layout space in the vehicle, the process of installing each component on the vehicle is more difficult, requiring a lot of man-hours to install and connect each component and hose individually. Furthermore, due to the complex routing, the flow resistance on the coolant side is high, resulting in a high load on the water pump.

[0008] KR 10-1765578B1, published on July 10, 2012, describes information related to embodiments of the present invention. Summary of the Invention

[0009] This invention relates to a water supply module and an electrical equipment cooling system including the water supply module. Specific embodiments relate to a water supply module capable of integrating and connecting various components used for cooling and heating in an environmentally friendly vehicle, and an electrical equipment cooling system including the water supply module.

[0010] Embodiments of the present invention provide a water supply module and an electrical equipment cooling system including the water supply module. The water supply module and the electrical equipment cooling system have the following advantages: reducing the number of components and labor time by integrally connecting each component of the cooling system, increasing installation convenience through modularity, reducing water pump load, and increasing the scalability of component combination.

[0011] An exemplary embodiment of the present invention provides a water supply module, including a water tank in which a first coolant and a second coolant with different temperatures are separated and contained; a heat exchanger having a coolant passage through which the first coolant and the second coolant flow and a refrigerant passage capable of exchanging heat with the coolant passage, and the heat exchanger being integrated into the water tank; and a controller integrated into the water tank and including a directional control valve for controlling the flow of coolant in multiple directions.

[0012] The internal space of the water storage tank can be divided by a partition to form a first containment section for containing a first coolant and a second containment section for containing a second coolant.

[0013] The first and second coolants can flow separately without mixing with each other.

[0014] The directional control valve can be connected to the water tank and heat exchanger to control the flow of coolant in six directions.

[0015] The water supply module may further include a first coolant pump and a second coolant pump, which are integrated with and communicate with a controller. The internal space of the water storage tank may be divided by a partition to form a first receiving portion for receiving the first coolant and a second receiving portion for receiving the second coolant. In the heat exchanger, the first and second coolants can be separated and flow separately. The water storage tank may be provided with a through-channel, through which the heat exchanger and the controller located on opposite sides communicate with each other, but the through-channel does not communicate with the first and second receiving portions of the water storage tank. The controller may communicate with both the first and second receiving portions of the water storage tank, and with both the first and second coolant channels of the heat exchanger. The controller can control the flow of coolant in at least six directions.

[0016] The coolant inlet of the first coolant pump can be connected to the first outlet of the controller, and the coolant inlet of the second coolant pump can be connected to the second outlet of the controller.

[0017] The water storage tank may have a first through passage through the first housing but isolated from the internal space of the first housing and a second through passage through the second housing but isolated from the internal space of the second housing. The first-2 inlet of the controller and the first coolant outlet of the heat exchanger may be connected through the first through passage, and the second-2 inlet of the controller and the second coolant outlet of the heat exchanger may be connected through the second through passage.

[0018] The water tank may have a first mounting portion recessed on one side in the longitudinal direction, on which a heat exchanger may be mounted, and the water tank may have a second mounting portion recessed on the other side in the longitudinal direction, on which a controller may be mounted.

[0019] The controller, the first coolant pump, and the second coolant pump can be configured as an integral assembly, and the first coolant pump can be installed on one side of the controller in the width direction, and the second coolant pump can be installed on the other side of the controller in the width direction.

[0020] The controller may also include a housing having a first inlet, a first inlet, a second inlet, a second inlet, and a third inlet through which coolant flows, and a first outlet and a second outlet through which coolant is discharged. A directional control valve may be disposed within the housing, and the inlets and outlets of the controller may be connected to correspond to the six ports of the directional control valve.

[0021] The controller may also include a control unit that controls the operation of the first coolant pump, the second coolant pump, and the directional control valve.

[0022] The directional control valve may include a housing with six ports and a rotating body disposed within the housing to divide the internal space of the housing into four regions and to be rotatable about a center.

[0023] Of the six ports, the first port can be connected to the first housing of the water tank, the second port can be connected to the first coolant pump, the third port can be connected to the first coolant outlet of the heat exchanger, the fourth port can be connected to the second housing of the water tank, the fifth port can be connected to the second coolant pump, and the sixth port can be connected to the second coolant outlet of the heat exchanger.

[0024] In the first mode based on the rotational position of the rotating body, the first receiving portion of the water tank can be connected to the first coolant pump and the second receiving portion of the water tank can be connected to the second coolant pump.

[0025] In the second mode, based on the rotational position of the rotating body, the first coolant outlet of the heat exchanger can be connected to the first coolant pump and the second coolant outlet of the heat exchanger can be connected to the second coolant pump.

[0026] In the third mode, based on the rotational position of the rotating body, the first receiving portion of the water tank can be connected to the first coolant pump, and the second coolant outlet of the heat exchanger can be connected to the second coolant pump.

[0041] In the following, a water supply cooling module having the above-described structure according to an embodiment of the present invention and an electrical equipment cooling system including the water supply cooling module will be described in detail with reference to the accompanying drawings.

[0042] Figure 1 This is a perspective view showing the assembly of a water supply module according to an exemplary embodiment of the present invention. Figure 2 This is an exploded perspective view of the water supply module and a structural diagram showing the electrical equipment cooling system including the water supply module. Figure 3 This is a three-dimensional view showing the cross-section of the water storage tank in the water supply module. Figure 4a and Figure 4b This is a conceptual diagram showing the front view and top view of a heat exchanger in a water supply module according to an exemplary embodiment of the present invention. Figure 5 This is a cross-sectional view showing the controller housing and the directional control valve.

[0043] As shown in the figure, the water supply module according to an exemplary embodiment of the present invention may mainly include a water storage tank 100, a heat exchanger 200, a controller 300, a directional control valve 400, a first coolant pump 510, and a second coolant pump 520.

[0044] In addition, the electrical equipment cooling system can be configured to include a water supply module, a first electrical component 610 and a second electrical component 620, and may further include a first radiator 710 and a second radiator 720.

[0045] The water tank 100 is used to store and supply a first coolant and a second coolant that flow along different paths, and can be configured such that the first coolant and the second coolant do not mix with each other.

[0046] For example, the water storage tank 100 can be formed in such a way that the container having an empty space for containing coolant is provided with a partition 103 that separates the internal space.

[0047] In the water storage tank 100, the first container 110 for containing the first coolant and the second container 120 for containing the second coolant can be integrally formed.

[0048] Furthermore, the water storage tank can be formed in various forms. In addition, the water storage tank 100 has a first mounting portion 101 formed recessed on one side in the longitudinal direction, so that the heat exchanger 200 is mounted on the first mounting portion 101, and the water storage tank 100 has a second mounting portion 102 formed recessed on the other side in the longitudinal direction, so that the controller can be mounted on the second mounting portion 102.

[0049] In addition, the water storage tank 100 has a first through passage 130 that passes through the first receiving portion 110 but is isolated from the internal space of the first receiving portion 110 and a second through passage 140 that passes through the second receiving portion 120 but is isolated from the internal space of the second receiving portion 120.

[0050] That is, the first through channel 130 is formed to pass through one side surface in the length direction of the first mounting part 101 and the other side surface in the length direction of the second mounting part 102, and is formed such that the space between the entrance and exit of the first through channel 130 is not connected to the internal space of the first receiving part 110.

[0051] Similarly, the second through channel 140 is formed to pass through one side surface in the length direction of the first mounting portion 101 and the other side surface in the length direction of the second mounting portion 102, and is formed such that the space between the entrance and exit of the second through channel 140 is not connected to the internal space of the second receiving portion 120.

[0052] The heat exchanger 200 may be, for example, a refrigerator that transfers heat generated from power electronic (PE) components (as electrical components) or batteries to a refrigerant.

[0053] The heat exchanger 200 can be configured such that the first coolant flowing along the first electrical component 610 and the second coolant flowing along the second electrical component 620 can remain unmixed with each other, and both the first and second coolants can exchange heat with the refrigerant.

[0054] That is, as shown in the figure, the heat exchanger 200 may be provided with a first coolant channel 210 and a second coolant channel 220. The first coolant can flow through the first coolant channel alone, and the second coolant can flow through the second coolant channel alone.

[0055] Furthermore, a first coolant inlet 211 and a first coolant outlet 212, which are connected to the first coolant passage 210, can be formed on the surface of the water tank 100 facing the first mounting portion 101.

[0056] Furthermore, a second coolant inlet 221 and a second coolant outlet 222, which are connected to the second coolant passage 220, can be formed on the surface of the water tank 100 facing the first mounting portion 101.

[0057] Therefore, the heat exchanger 200 is installed on the first mounting part 101 of the water storage tank 100, so the first coolant outlet 112 of the heat exchanger 200 can be connected to the inlet of the first through channel 130 of the water storage tank 100, and the second coolant outlet 122 can be connected to the inlet of the second through channel 140.

[0058] Here, the first coolant inlet 111 and the second coolant inlet 121 of the heat exchanger 200 may be configured to be exposed to the outside of the water tank 100.

[0059] In addition, the heat exchanger 200 may have a refrigerant passage 230 through which refrigerant flows, and the refrigerant passage 230 may be formed adjacent to the first coolant passage 210 and the second coolant passage 220.

[0060] The controller 300 is connected to the water tank 100, the heat exchanger 200, the first coolant pump 510 and the second coolant pump 520. The controller 300 may include a directional control valve (6-way valve) 400, which can control the flow of coolant in six directions.

[0061] For example, the controller 300 may include a housing 310 and a directional control valve 400 disposed therein, and the housing 310 may be provided with a first-1 inlet 301, a first-2 inlet 302, a second-1 inlet 303 and a second-2 inlet 304 formed on the surface of the water tank 100 facing the second mounting portion 102, which are four inlets for coolant to flow in.

[0062] Therefore, the controller 300 is installed on the second mounting part 102 of the water storage tank 100, so the first inlet 301 can be connected to the coolant outlet of the first receiving part 110, the first inlet 302 can be connected to the outlet of the first through channel 130, the second inlet 303 can be connected to the coolant outlet of the second receiving part 120, and the second inlet 304 can be connected to the outlet of the second through channel 140.

[0063] Furthermore, the housing 310 of the controller 300 may have a first outlet 305 for discharging coolant on one side surface in the width direction, and a second outlet 306 for discharging coolant on the other side surface in the width direction.

[0064] The directional control valve 400 may include a housing 410 and a rotating body 420 disposed within the housing 410 and rotatably formed about a center.

[0065] For example, the housing 410 may be formed in a cylindrical shape, and the housing 410 may include six ports, including a first port 411, a second port 412, a third port 413, a fourth port 414, a fifth port 415 and a sixth port 416, which pass through the outer peripheral surface and the inner peripheral surface and are formed in a manner spaced apart along the circumferential direction.

[0066] Furthermore, the rotating body 420 can be formed into various shapes, such that by combining with the housing 410, the internal space of the housing 410 is divided into four regions.

[0067] Here, depending on the rotational position of the rotating body 420, two adjacent ports can be connected to or disconnected from each other.

[0068] Furthermore, based on the center of rotation, two adjacent ports can be connected to each other, and two adjacent ports on opposite sides can also be connected to each other. In addition, the connection between any two ports other than those connected to each other can be blocked.

[0069] Furthermore, the directional control valve 400 can be disposed within the housing 310 of the controller 300, and the housing 410 of the directional control valve 400 can be coupled to and fixed to the inner surface of the housing 310.

[0070] Therefore, the first-1 inlet 301 of the outer casing 310 can be connected to the first port 411, the first-2 inlet 302 can be connected to the third port 413, the second-1 inlet 303 can be connected to the sixth port 416, and the second-2 inlet 304 can be connected to the fourth port 414.

[0071] In addition, the first outlet 305 of the housing 310 can be connected to the second port 412, and the second outlet 306 can be connected to the fifth port 415.

[0072] A first coolant pump 510 is connected to a controller 300 for pressurizing a first coolant. The first coolant pump 510 may be coupled to one side of the controller 300 in the width direction, and the coolant inlet of the first coolant pump 510 may be connected to a first outlet 305 of the housing 310.

[0073] The second coolant pump 520 is connected to the controller 300 for pressurizing the second coolant.

[0074] The second coolant pump 520 can be coupled to the other side of the controller 300 in the width direction, and the coolant inlet of the second coolant pump 520 can be connected to the second outlet 306 of the housing 310.

[0075] Here, the first coolant pump 510 and the second coolant pump 520 can face each other around the controller 300.

[0076] Furthermore, the coolant inlet of the first coolant pump 510 and the coolant inlet of the second coolant pump 520 can be arranged to face each other, and the coolant outlet of the first coolant pump 510 and the coolant outlet of the second coolant pump 520 can be formed on the same side of each other.

[0077] Furthermore, the controller 300, including the directional control valve 400, the first coolant pump 510, and the second coolant pump 520, are constructed as an integral component in which they are assembled, and can be combined with the water tank 100 in the assembled state.

[0078] In addition, although not shown, the controller 300 may also include a controller for controlling the operation of the first coolant pump 510, the second coolant pump 520 and the directional control valve 400, and the controller 300 may also include a drive unit capable of controlling the rotational position of the rotating body 420 in the directional control valve 400.

[0079] Here, the directional control valve 400 can operate in the following three modes depending on the rotational position of the rotating body 420.

[0080] See Figure 6In the first mode, the first housing portion 110 of the water tank 100 and the first coolant pump 510 are connected to each other, and the second housing portion 120 of the water tank 100 and the first coolant pump 510 are connected to each other.

[0081] That is, the first port 411 and the second port 412 of the directional control valve 400 are connected to each other, the fourth port 414 and the fifth port 415 are connected to each other, and the third port 413 and the sixth port 416 are disconnected from each other.

[0082] Therefore, the first coolant and the second coolant cannot flow from the heat exchanger 200 to the directional control valve 400. The first coolant can flow from the first receiving portion 110 of the water tank 100 to the first coolant pump 510, and the second coolant can flow from the second receiving portion 120 of the water tank 100 to the second coolant pump 520.

[0083] See Figure 7 In the second mode, the first coolant outlet 212 of the heat exchanger 200 and the first coolant pump 510 can be connected to each other, and the second coolant outlet 222 of the heat exchanger 200 and the first coolant pump 510 can be connected to each other.

[0084] That is, the second port 412 and the third port 413 of the directional control valve 400 are connected to each other, the fifth port 415 and the sixth port 416 are connected to each other, and the first port 411 and the fourth port 414 are disconnected from each other.

[0085] Therefore, neither the first coolant nor the second coolant can flow from the water tank 100 to the directional control valve 400. The first coolant can flow from the first coolant outlet 212 of the heat exchanger 200 to the first coolant pump 510, and the second coolant can flow from the second coolant outlet 222 of the heat exchanger 200 to the second coolant pump 520.

[0086] See Figure 8 In the third mode, the first containment 110 of the water tank 100 and the first coolant pump 510 can be connected to each other, and the second coolant outlet 222 of the heat exchanger 200 and the second coolant pump 520 can be connected to each other.

[0087] That is, the first port 411 and the second port 412 of the directional control valve 400 are connected to each other, the fifth port 415 and the sixth port 416 are connected to each other, and the third port 413 and the fourth port 414 are disconnected from each other.

[0088] Therefore, the first coolant does not flow from the first coolant outlet 212 of the heat exchanger 200 to the directional control valve 400, but flows from the first receiving part 110 of the water tank 100 to the first coolant pump 510.

[0089] Furthermore, the second coolant cannot flow from the second containment 120 of the water tank 100 to the directional control valve 400, and the second coolant can flow from the second coolant outlet 222 of the heat exchanger 200 to the second coolant pump 520.

[0090] Alternatively, in the third mode, when Figure 8 When the rotating body 420 shown rotates 180°, the second port 412 and the third port 413 of the directional control valve 400 can be connected to each other, the fourth port 414 and the fifth port 415 can be connected to each other, and the first port 411 and the sixth port 416 can be disconnected from each other.

[0091] Therefore, the first coolant flows from the first coolant outlet 212 of the heat exchanger 200 to the first coolant pump 510, and the first coolant does not flow from the first receiving portion 110 of the water tank 100 to the directional control valve 400. Furthermore, the second coolant can flow from the second receiving portion 120 of the water tank 100 to the second coolant pump 520, and the second coolant cannot flow from the second coolant outlet 222 of the heat exchanger 200 to the directional control valve 400.

[0092] Therefore, the water supply module according to embodiments of the present invention can reduce the size and weight of the cooling system by removing hoses or pipes or by shortening the length of pipes by integrating components constituting the cooling system.

[0093] Furthermore, in the electrical equipment cooling system including the water supply module in this embodiment of the invention, the first electrical component 610 and the second electrical component 620 may be PE components or batteries, and the first electrical component 610 may be connected to the first coolant channel, and the coolant outlet of the first coolant pump 510 and the first coolant inlet 211 of the heat exchanger 200 are connected at the first coolant channel.

[0094] Therefore, the first coolant exchanges heat with the first electrical component 610, so that the first electrical component 610 can be cooled or heated.

[0095] In addition, the second electrical component 620 can be connected to the second coolant flow path, and the coolant outlet of the second coolant pump 520 and the second coolant inlet 221 of the heat exchanger 200 are connected at the second coolant flow path.

[0096] Therefore, the second coolant exchanges heat with the second electrical component 620, so that the second electrical component 620 can be cooled or heated.

[0097] Furthermore, the first receiving portion 110 of the water tank 100 and the first coolant inlet 211 of the heat exchanger 200 can be connected in parallel to the coolant outlet of the first electrical component 610, and the second receiving portion 120 of the water tank 100 and the second coolant inlet 221 of the heat exchanger 200 can be connected in parallel to the second electrical component 620.

[0098] Therefore, the flow of coolant can be formed in the three modes described above, depending on the control of the directional control valve 400.

[0099] In addition, the first radiator 710 can be connected between the coolant outlet of the first electrical component 610 and the first receiving portion 110 of the water tank 100, so that the first coolant can be cooled by the first radiator 710.

[0100] In addition, the second radiator 720 can be connected between the coolant outlet of the second electrical component 620 and the second receiving portion 120 of the water tank 100, so that the second coolant can be cooled by the second radiator 720.

[0101] Furthermore, the first and second coolants are maintained at different temperatures, and the flow rate of each coolant can be controlled according to the temperature of the electrical components and the external temperature.

[0102] As described above, the electrical equipment cooling system including a water supply module in this embodiment of the invention can reduce the number of components and assembly time of the cooling system and increase the convenience of installation.

[0103] In addition, it can reduce the flow resistance on the coolant side of the cooling system, thus reducing the load applied to the coolant pump and improving the performance and durability of the cooling system.

[0104] Figure 9 and Figure 10 These are assembled perspective views and exploded perspective views illustrating the modeling of a water supply module according to an exemplary embodiment of the present invention.

[0105] As shown in the figure, in the water supply module according to an exemplary embodiment of the present invention, the first coolant inlet 111 and the second coolant inlet 121 of the water storage tank 100 may be formed on the side surface in the width direction.

[0106] Furthermore, two branch pipes are connected to the first coolant inlet 211 of the heat exchanger 200, so all branch pipes can be connected to the first coolant inlet 211.

[0107] Similarly, two branch pipes are connected to the second coolant inlet 221, so all branch pipes can communicate with the second coolant inlet 221.

[0108] Therefore, referring to FIG12, the flow path of the first coolant in the electrical equipment cooling system including the water supply module according to an exemplary embodiment of the present invention can be formed as shown.

[0109] Here, the first electrical component 610 may be a battery and coolant heater, and the first radiator 710 may be a radiator on the low-temperature side.

[0110] In Figure 12, only the flow of the first coolant is shown, but the second coolant can be configured to flow in the same manner as the first coolant, and only the construction of the second electrical components and the second radiator can be different.

[0111] This invention is not limited to the exemplary embodiments described above, but can be applied in various ways. Furthermore, those skilled in the art can make various modifications to the embodiments of this invention without departing from the spirit of the invention as claimed in the claims.
