Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to and the benefit of Korean Patent Application No. 10-2023-0128730 filed in the Korean Intellectual Property Office on September 26, 2023, the entire contents of which are incorporated herein by reference. Technical Field

[0003] The present disclosure relates to a liquid storage tank assembly and a heat pump system including the liquid storage tank assembly. Background Art

[0004] Generally, an air conditioning device applied to an environmentally friendly vehicle is often referred to as a heat pump system.

[0005] This heat pump system for a vehicle is provided with a reservoir tank to cope with the change in volume of the coolant according to the change in the temperature of the coolant. When the coolant is heated and its volume expands, some of the coolant is temporarily stored in the reservoir tank. When the coolant is cooled and the volume decreases, the coolant stored in the reservoir tank is supplemented to the cooling line.

[0006] Due to the heating and cooling of the coolant, air may be contained in the coolant. When excessive air is contained in the coolant, the cooling efficiency of the coolant is reduced and the volume of the coolant in the entire heat pump system increases. In addition, when the coolant flows, noise is generated due to the air contained in the coolant, which has an adverse effect on the blades of the coolant pump.

[0007] Increasing the capacity of the tank can solve this problem, but it will also increase the volume of the tank and adversely affect vehicle packaging.

[0008] The matters described in this background technology section are provided only to enhance understanding of the present disclosure and may include matters that are not known to a person of ordinary skill in the art to which the present technology belongs. Summary of the invention

[0009] The present disclosure provides a liquid storage tank capable of removing air contained in a coolant and a heat pump system including the liquid storage tank.

[0010] In an embodiment of the present disclosure, the reservoir assembly may include: a housing, in which a degassing chamber configured to store a coolant is formed; and an inlet pipe formed in the housing and into which the coolant flows. The reservoir assembly may further include: an outlet pipe formed in the housing and through which the coolant is discharged; and a connecting conduit that fluidly connects the inlet pipe and the outlet pipe and is arranged to pass through the degassing chamber. In particular, some of the coolant flowing through the inlet pipe flows into the connecting conduit after passing through the degassing chamber, and the remaining coolant is discharged to the outside of the housing without passing through the degassing chamber.

[0011] In one embodiment, the housing may include a lower housing and an upper housing disposed above the lower housing, and the lower housing and the upper housing together form a degassing chamber.

[0014] The conduit inlet may be formed by a space between the inlet conduit and the outlet conduit.

[0015] The conduit outlet may be formed by a space between an interior lower surface of the housing and the inlet conduit.

[0016] In one embodiment, a portion of the coolant sucked into the inlet conduit through the inlet conduit may flow into the degassing chamber through the conduit hole, and the remaining coolant sucked into the inlet conduit and the coolant that has passed through the degassing chamber may be discharged to the outlet conduit through the outlet conduit. The coolant discharged to the outlet conduit may be supplied to the coolant pipeline.

[0017] In another embodiment, a heat pump system may include: a coolant pipeline through which a coolant flows; an inlet pipe branching from a first end of the coolant pipeline; an outlet pipe branching from a second end of the coolant pipeline; and a liquid storage tank. The liquid storage tank includes: a shell in which a degassing chamber is formed; and a connecting conduit fluidically connecting the inlet pipe and the outlet pipe and passing through the degassing chamber. In particular, some of the coolant flowing through the inlet pipe flows into the connecting conduit after passing through the degassing chamber, and the remaining coolant is discharged to the outside of the shell without passing through the degassing chamber.

[0018] In one embodiment, the housing may include a lower housing and an upper housing disposed above the lower housing. In particular, the lower housing and the upper housing together form a degassing chamber.

[0019] In one embodiment, the connecting conduit may include: a conduit inlet formed in the connecting conduit; and a conduit outlet formed in the connecting conduit and disposed below the conduit inlet.

[0020] In one embodiment, the connecting conduit may further include: an inlet conduit fluidly connected to the inlet pipe; and an outlet conduit partially connected to the inlet conduit and fluidly connected to the outlet pipe.

[0021] The conduit inlet may be formed by a space between the inlet conduit and the outlet conduit.

[0022] The conduit outlet may be formed by a space between an interior lower surface of the housing and the inlet conduit.

[0023] In one embodiment, a portion of the coolant sucked into the inlet conduit through the inlet conduit may flow into the degassing chamber through the conduit hole, and the remaining coolant sucked into the inlet conduit and the coolant that has passed through the degassing chamber may be discharged to the outlet conduit through the outlet conduit. The coolant discharged to the outlet conduit may be supplied to the coolant pipeline.

[0024] According to the liquid storage tank assembly and the heat pump system including the same disclosed herein, the air contained in the coolant flowing through the coolant pipeline can be effectively removed by arranging the liquid storage tank and the coolant pipeline in parallel.

[0025] By removing the air contained in the coolant, the cooling efficiency can be improved and the capacity of the reservoir tank can be reduced, thereby obtaining an advantageous effect in terms of packaging the vehicle.

It should be understood that the present disclosure includes all modifications, equivalents and substitutions contained in the spirit and technical scope of the present disclosure.

[0080] According to an embodiment of the present disclosure, a heat pump system to which a liquid storage tank assembly is applied is described in detail with reference to the accompanying drawings.

[0081] Figure 1 is a block diagram of a heat pump system including a fluid storage tank assembly according to an embodiment.

[0082] like Figure 1 As shown, the heat pump system applying the reservoir assembly 300 may include a first cooling circuit 100 configured to cool at least one electrical component 140 and a second cooling circuit 200 configured to cool a battery. In the present disclosure, a heat pump system applied to an electric vehicle is described as an example, but the scope of the present disclosure is not limited thereto.

[0083] In one embodiment, the first cooling circuit 100 may include a first radiator 120, a reservoir assembly 300, and an electrical assembly 140 disposed in a first coolant line 111 through which coolant flows. The first radiator 120, the reservoir assembly 300, and the electrical assembly 140 may be disposed in the first coolant line 111 sequentially.

[0084] In one embodiment, the second cooling circuit 200 may include a second radiator 220, a reservoir assembly 300, a battery module 230, a battery heater 240, and a battery cooler 250 disposed in a second coolant line 211 through which the coolant flows. The second radiator 220, the reservoir assembly 300, the battery module 230, the battery heater 240, and the battery cooler 250 may be sequentially disposed in the second coolant line 211.

[0085] like Figure 1 As shown, the reservoir assembly 300 is arranged to overlap with the first coolant line 111 and the second coolant line 211. In other words, the first cooling circuit 100 and the second cooling circuit 200 share the reservoir assembly 300. The coolant cooled by the first radiator 120 is stored in the housing of the reservoir assembly 300 through the first coolant line 111, and the coolant cooled by the second radiator 220 is stored in the housing of the reservoir assembly 300 through the second coolant line 211. Optionally, the reservoir assembly 300 may also be arranged in each of the first coolant line 111 and the second coolant line 211.

[0086] In one embodiment, the first water pump 170 is disposed on the downstream side of the reservoir assembly 300 in the first coolant line 111, and the second water pump 270 is also disposed on the downstream side of the reservoir assembly 300 in the second coolant line 211. The coolant stored in the reservoir of the reservoir assembly 300 is supplied to the first coolant line 111 by the operation of the first water pump 170, and is supplied to the second coolant line 211 by the operation of the second water pump 270. In one form of the present disclosure, the reservoir assembly 300, the first water pump 170, and the second water pump 270 may be integrated (or integrally formed).

[0087] The first cooling circuit 100 is described in more detail.

[0088] The first radiator 120 is disposed at the front of the vehicle, and the cooling fan 130 is disposed behind the first radiator 120 to cool the coolant flowing through the first coolant line 111 through operation of the cooling fan 130 and heat exchange with ambient air.

[0089] The electrical component 140 may include at least one of a power control device, an inverter, a power conversion device such as an on-board charger (OBC), a drive motor, or an autonomous driving controller. The power control device, the inverter, or the autonomous driving controller may generate heat when driving, and the on-board charger may generate heat when charging the battery. The electrical component 140 may be disposed in the first coolant line 111 and cooled by water cooling.

[0090] In one embodiment, a first branch line 112 may be provided in the first cooling circuit 100. The first branch line 112 may branch from an upstream portion of the first coolant line 111 and join to a downstream portion of the first coolant line 111 while bypassing the first radiator 120. A first valve 113 may be provided at a point where the first branch line 112 and the first coolant line 111 join. The first valve 113 may be implemented as a three-way valve.

[0091] The coolant flowing through the first coolant line 111 is selectively supplied to the first radiator 120 by the operation of the first valve 113. For example, when it is necessary to cool the electric component 140, the first valve 113 is operated to open the first coolant line 111 while closing the first branch line 112, so that the coolant cools the electric component 140, and the coolant heated by heat exchange with the electric component 140 is cooled while passing through the first radiator 120. On the contrary, when it is not necessary to cool the electric component 140 by the coolant cooled by the first radiator 120, the first coolant line 111 passing through the first radiator 120 is closed by the operation of the first valve 113, and the first branch line 112 and the first coolant line 111 are fluidly connected to each other, so that the coolant is not supplied to the first radiator 120.

[0092] The second cooling circuit 200 is described in further detail.

[0093] The second radiator 220 is disposed in front of the first radiator 120, and cools the coolant flowing through the second coolant line 211 by operation of the cooling fan 130 and heat exchange with ambient air. If necessary, the first radiator 120 and the second radiator 220 may also be integrally constructed.

[0094] The second cooling circuit 200 may selectively supply the coolant cooled at the second radiator 220 to the battery module 230 .

[0095] If necessary, the battery heater 240 may heat the battery module 230. The battery heater 240 may be an electric heater that operates using electricity. For example, the battery heater 240 operates when the temperature of the coolant supplied to the battery module 230 is lower than the target temperature, and may heat the coolant flowing through the second coolant loop. Therefore, the coolant heated while passing through the battery heater 240 is supplied to the battery module 230, and the temperature of the battery module 230 may be increased.

[0096] If necessary, the battery cooler 250 may cool the battery module 230. The battery cooler 250 may reduce the temperature of the coolant sucked through the second coolant line 211 by exchanging heat with the refrigerant. The low-temperature coolant exchanging heat with the refrigerant at the battery cooler 250 may flow to the battery module 230 and cool the battery module 230.

[0097] In one embodiment, a second branch line 212 and a third branch line 213 may be provided in the second cooling circuit 200. The second branch line 212 may be branched from the upstream portion of the second coolant line 211 and joined to the downstream portion of the second coolant line 211 while bypassing the second radiator 220. The third branch line 213 may be branched from another downstream portion of the second coolant line 211 located on the downstream side of the battery cooler 250 and joined to another upstream portion of the second coolant line 211 located on the upstream side of the battery module 230. The second valve 214 may be provided at a point where the third branch line 213 and the second coolant line 211 are joined. The second valve 214 may be implemented as a three-way valve.

[0098] The coolant flowing through the second coolant line 211 is selectively supplied to the second radiator 220 by operation of the second valve 214 .

[0099] For example, when the coolant cooled by the second radiator 220 is needed to cool the battery module 230, the flow of coolant from the second coolant line 211 to the third branch line 213 is blocked by the operation of the second valve 214, and the second coolant line 211 passing through the second radiator 220 is opened, so that the coolant heated by heat exchange with the battery module 230 is cooled by the second radiator 220.

[0100] On the contrary, when the coolant cooled by the second radiator 220 is not needed to cool the battery module 230, the coolant flow along the second coolant line 211 passing through the second radiator 220 is blocked by the operation of the second valve 214, and the third branch line 213 and the second coolant line 211 are fluidly connected to each other so that the coolant is not supplied to the second radiator 220. In this case, the second cooling circuit 200 forms two closed circuits. In other words, one closed circuit circulating the second radiator 220, the reservoir assembly 300 and the second water pump 270, and another circuit circulating the battery module 230, the battery heater 240 and the battery cooler 250 are formed.

[0101] In one embodiment, the water-cooled heat exchanger 260 may be disposed to overlap the first coolant line 111 and the second coolant line 211. Through the water-cooled heat exchanger 260, the coolant flowing through the first coolant line 111 and the coolant flowing through the second coolant line 211 may exchange heat with each other.

[0102] Hereinafter, the fluid storage tank assembly 300 is described in detail with reference to the accompanying drawings.

[0103] Figure 2 1 is a schematic diagram showing a configuration in which a liquid storage tank assembly according to an embodiment is applied to a coolant line. Figure 3 is a perspective view showing a fluid reservoir assembly according to an embodiment. Figure 4 is a cross-sectional perspective view of a liquid storage tank assembly according to an embodiment. Figure 5 is a cross-sectional view of a fluid storage tank assembly according to an embodiment.

[0104] Reference Figure 2 , the degassing chamber 360 formed in the reservoir assembly 300 is provided in parallel with the connecting conduit 340 in the housing 310. Some of the coolant flowing from the coolant line into the connecting conduit 340 fluidly connected to the coolant line flows back into the connecting conduit 340 after passing through the degassing chamber 360. And the remaining coolant flowing into the connecting conduit 340 flows through the connecting conduit 340 and is discharged to the outside of the reservoir assembly 300 without passing through the degassing chamber 360.

[0105] Reference Figures 3 to 5 , the reservoir assembly 300 may include: a housing 310 forming a space (e.g., a degassing chamber 360) for storing a coolant; an inlet pipe 321 formed in the housing 310 and into which the coolant flows; and an outlet pipe 331 formed in the housing 310 and through which the coolant is discharged. The inlet pipe 321 branches from the coolant line and fluidically connects the coolant line and the housing. And the outlet pipe 331 branches from the coolant line and fluidically connects the coolant line and the housing 310. A degassing chamber 360 and a connecting conduit 340 configured to remove air contained in the coolant are formed inside the housing 310.

[0106] The housing 310 may include a lower housing 330 and an upper housing 320 disposed above the lower housing 330. The lower housing 330 and the upper housing 320 together form a degassing chamber 360 therein.

[0107] A connecting conduit 340 fluidly connected to the inlet conduit 321 and the outlet conduit 331 is disposed inside the housing 310. The connecting conduit 340 fluidly connecting the coolant line through the inlet conduit 321 and the outlet conduit 331 may be disposed to pass through the degassing chamber 360. A conduit outlet 346 is disposed below the conduit inlet 345. The connecting conduit 340 includes: an inlet conduit 341 fluidly connected to the inlet conduit 321; and an outlet conduit 343 partially fluidly connected to the inlet conduit 341 and fluidly connected to the outlet conduit 331. A conduit inlet 345 and a conduit outlet 346 are formed in the inlet conduit 321 and the outlet conduit 331. Through the conduit inlet 345 and the conduit outlet 346, the inlet conduit 341 and the outlet conduit 343 are partially fluidly connected to each other. The inlet conduit 341 and the outlet conduit 343 may be vertically disposed inside the housing 310.

[0108] Reference Figure 6 and Figure 7 The upper housing 320 is formed in a substantially hexahedral shape having a hollow interior and has an open bottom. An inlet pipe 321 is provided on a side surface of the upper housing 320, and an inlet conduit 341 fluidly connected to the inlet pipe 321 is provided on an upper inner side of the upper housing 320. The inlet conduit 341 may be formed to extend vertically from the upper inner side of the upper housing 320.

[0109] The inlet duct 341 may be formed in a substantially hexahedral shape having a hollow interior. A partially cut inlet cutout 342 is formed in a lower portion of the inlet duct 341. The lower end of the inlet duct 341 is spaced apart from the inner lower surface of the lower housing 330 by a preset interval to form a duct outlet 346.

[0110] Reference Figure 8 and Fig. 9 The lower housing 330 is formed in a substantially hexahedral shape having a hollow interior and has an open top. An outlet conduit 343 partially fluidly connected to the inlet conduit 341 is provided at the lower inner side of the lower housing 330, and an outlet pipe 331 fluidly connected to the outlet conduit 343 is provided at the lower part of the lower housing 330. The outlet conduit 343 may be formed to extend vertically from the lower inner side of the lower housing 330.

[0111] The outlet duct 343 may correspond to the inlet duct 341 and may be formed in a substantially hexahedral shape having a hollow interior. An outlet cutout 344 is partially cut and formed in an upper portion of the outlet duct 343 .

[0112] The inlet cutout 342 and the outlet cutout 344 are formed in shapes corresponding to each other, and a lower portion of the inlet cutout 342 and an upper portion of the outlet cutout 344 are spaced apart by a preset interval to form a duct inlet 345 .

[0113] In one embodiment, the inlet cutout 342 and the outlet cutout 344 are spaced apart from each other by a predetermined interval in a direction perpendicular to the length direction to form a conduit intermediate passage 347. In addition, the width W1 of the inlet conduit 341 may be wider than the width W2 of the outlet conduit 343.

[0114] Since the width W1 of the inlet duct 341 is wider than the width W2 of the outlet duct 343, the duct inlet 345 can be significantly enlarged. With this configuration, the amount of coolant supplied from the inlet duct 341 through the duct inlet 345 to the degassing chamber 360 can be increased.

[0115] In addition, since the duct middle passage 347 is formed, the coolant may be smoothly supplied from the inlet duct 341 to the degassing chamber 360 .

[0116] Hereinafter, the flow of the coolant through the reservoir assembly 300 according to the present disclosure is described.

[0117] All coolant flowing along the coolant line flows into the inlet conduit 341 of the housing 310 through the inlet pipe 321 .

[0118] A portion of the coolant drawn into the inlet conduit 341 is introduced into the degassing chamber 360 through the conduit inlet 345. The remaining portion of the coolant drawn into the inlet conduit 341 is supplied to the coolant line through the outlet conduit 343 and the outlet pipe 331.

[0119] For the coolant sucked into the degassing chamber 360, the flow rate of the coolant decreases and the turbulence intensity of the coolant decreases during the process of passing through the degassing chamber 360. As the flow rate and turbulence intensity of the coolant decrease, air contained in the coolant is discharged from the coolant.

[0120] The coolant exhausted from the air is supplied to the coolant line through the conduit outlet 346 , the outlet conduit 343 , and the outlet pipe 331 .

[0121] In this way, air contained in the coolant can be smoothly removed through the degassing chamber 360 provided in parallel with the connection duct 340, so that the specific heat of the coolant circulating the entire heat pump system increases and the cooling performance can be enhanced.

[0122] In addition, since the coolant from which air is removed flows into the water pump, the NVH (noise, vibration and harshness) of the water pump can be improved.

[0123] In addition, since the air of the coolant is removed by providing the connection duct 340 in parallel with the degassing chamber 360 , the volume of the degassing chamber 360 of the reservoir assembly 300 may be minimized, thereby providing an advantage in terms of packaging of the vehicle.

[0124] Although the embodiments of the present disclosure have been described, the present disclosure is not limited thereto, and various modifications may be made within the scope of the present disclosure, the detailed description of the present disclosure, and the accompanying drawings, and these modifications naturally belong to the scope of the present disclosure.
