Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of automobile parts, and in particular to a water storage bottle and a vehicle. Background Art

[0002] A water storage bottle is connected to the cooling system of the car, which plays the role of fluid replenishment and gas-liquid separation in the cooling system.

[0003] Currently, return water from pressurized cryogenic water storage bottles often appears as a jet, which increases the risk of bubbles in the coolant within the bottle. Furthermore, existing pressurized cryogenic water storage bottles primarily utilize two- or three-chamber structures, which can lead to incomplete gas-liquid separation. Consequently, gas can enter the cooling chambers of various components along with the coolant, reducing the performance of the entire cooling system and even causing component durability degradation. Utility Model Content

[0004] In view of this, an embodiment of the present application provides a water storage bottle and a vehicle, which can avoid liquid injection, increase the flow range of the coolant, extend the gas-liquid separation time, improve the gas-liquid separation efficiency, and enhance the performance of the cooling system.

[0005] In order to achieve the above-mentioned purpose, the technical solution of the embodiment of the present application is implemented as follows:

[0006] On the one hand, an embodiment of the present application provides a water storage bottle, comprising a shell and a plurality of partition plates arranged in the shell, each partition plate separating a plurality of fluid chambers in the shell, and each fluid chamber being connected in sequence along the circumference of the shell so that the coolant in the shell flows along the circumference of the shell; wherein the plurality of fluid chambers comprise a return liquid chamber, a liquid outlet chamber and a guide chamber, the return liquid chamber and the liquid outlet chamber being adjacently arranged and not connected, the guide chamber being located in the return liquid chamber, and the guide chamber being connected to the return liquid chamber; a return liquid port and a liquid outlet port are provided on the shell, the return liquid port is connected to the guide chamber, and the liquid outlet port is connected to the liquid outlet chamber.

[0007] The water storage bottle provided in an embodiment of the present application includes a housing and multiple partitions disposed within the housing. Each partition defines multiple fluid chambers within the housing. The multiple fluid chambers are sequentially connected along the circumference of the housing and include adjacent, but not connected, return and discharge chambers. By separating a diversion chamber within the return chamber, a return port on the housing communicates with the diversion chamber, and a discharge port on the housing communicates with the discharge chamber. Cooling liquid enters the water storage bottle through the diversion chamber, flows through the sequentially connected fluid chambers, and then exits through the discharge chamber. Cooling liquid enters the return chamber from the smaller diversion chamber, resulting in less pressure change upon entering the water storage bottle. This allows for smoother inflow and mitigates the problem of incoming liquid impacting the liquid surface within the water storage bottle. Furthermore, the sequentially connected circumferential fluid chambers within the housing allow the cooling liquid to flow along the circumference of the housing, increasing the coolant flow path within the water storage bottle, extending the gas-liquid separation time, and improving gas-liquid separation efficiency. This improves the performance of the vehicle's entire cooling system.

[0008] In a possible embodiment, the partition plate includes a plurality of first partition plates sequentially arranged along the circumference of the shell, and each first partition plate separates a plurality of fluid chambers sequentially arranged along the circumference of the shell.

[0009] By sequentially disposing a plurality of first baffles along the circumference of the housing, each first baffle being connected to the inner sidewall of the housing at intervals along the circumference of the housing, a plurality of fluid chambers sequentially arranged along the circumference of the housing can be separated. This allows for a greater number of fluid chambers to be separated within the housing, and these multiple fluid chambers sequentially arranged along the circumference of the housing can be sequentially connected to achieve circumferential flow of coolant along the housing.

[0010] In a possible embodiment, the partition plate also includes a second partition plate, which is an annular partition plate and encloses a fluid cavity; one end of each first partition plate is connected to the inner wall of the shell, and the other end of each first partition plate is connected to the second partition plate.

[0011] By adding a second baffle to each first baffle, the shell is divided into multiple fluid chambers arranged in a circumferential direction, and a fluid chamber is also formed in the center of the shell. This increases the flow path of the coolant, prolongs the gas-liquid separation time of the coolant, and improves the gas-liquid separation efficiency of the water storage bottle.

[0012] In a possible implementation, at least four first partitions are sequentially spaced apart along the circumference of the shell, and at least six fluid chambers are separated in the shell.

[0013] By disposing at least four first baffles spaced apart along the circumference of the housing, these at least four first baffles can separate at least four fluid chambers arranged sequentially along the circumference of the housing. Together with the guide chamber and the fluid chamber located in the central region of the housing, the housing can be divided into at least six fluid chambers. This increases the number of fluid chambers within the housing, allowing the coolant to flow longer within the housing, resulting in a longer gas-liquid separation time and higher gas-liquid separation efficiency.

[0014] In a possible implementation, the flow guiding cavity extends from the top of the shell to the bottom of the shell, and the bottom of the flow guiding cavity is communicated with the bottom of the liquid return cavity.

[0015] By extending the diversion cavity from the top of the housing to the bottom of the housing and connecting its bottom to the bottom of the return chamber, the diversion cavity guides the coolant, preventing it from spurting when entering the housing. This prevents bubbles from forming when the coolant enters the housing, reduces the bubble content in the coolant, and ensures the performance of the entire vehicle system.

[0016] In a possible implementation, the diversion chamber is connected to a partition plate between the liquid return chamber and the liquid outlet chamber.

[0017] By connecting the guide cavity to the partition plate between the return liquid cavity and the liquid outlet cavity, the starting position where the coolant enters the shell and the ending position where it flows out of the shell are connected to the liquid outlet cavity, the flow distance of the coolant in the shell is longer, which is more conducive to the gas-liquid separation of the coolant.

[0018] In a possible implementation, along the flow direction of the coolant, the partition plates between adjacent fluid cavities are each provided with drainage holes, and the adjacent fluid cavities are connected through the drainage holes.

[0019] In a possible implementation, the opening area of each drainage hole gradually increases along the flow direction of the coolant.

[0020] Along the flow direction of the coolant, by gradually increasing the opening area of each drainage hole on the partition plate between the fluid cavities arranged in sequence, the flow area of the coolant is gradually increased, which can compensate for the flow rate loss of the coolant and make the flow rate of the coolant in the shell more uniform.

[0021] In a possible implementation, at least part of the fluid chamber is provided with an exhaust hole, and the exhaust hole is located at an upper portion of the housing.

[0022] On the other hand, an embodiment of the present application provides a vehicle, comprising the water bottle as described above.

[0023] The vehicle provided in the embodiment of the present application includes the aforementioned water bottle and thus has all the technical effects of the water bottle, which will not be described in detail here. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] To make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the specific technical solutions of the present application will be further described in detail below in conjunction with the drawings in the embodiments of the present application. The following embodiments are used to illustrate the present application but are not intended to limit the scope of the present application.

[0036] In the embodiments of this application, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of this application, unless otherwise specified, "multiple" means two or more.

[0037] In addition, in the embodiments of the present application, directional terms such as "up", "down", "left" and "right" are defined relative to the orientation of the components in the drawings. It should be understood that these directional terms are relative concepts. They are used for relative description and clarification, and they may change accordingly according to changes in the orientation of the components in the drawings.

[0038] In the embodiments of the present application, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integrated connection; it can be a direct connection or an indirect connection through an intermediate medium.

[0039] In the embodiments of the present application, the terms "comprises," "comprising," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not preclude the presence of other identical elements in the process, method, article, or apparatus comprising the element.

[0040] In the embodiments of this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of this application should not be interpreted as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0041] The embodiments of the present application provide a vehicle. The vehicle may refer to a large automobile, a small automobile, a special-purpose vehicle, and the like. For example, based on the vehicle type, the vehicle in the present application may be a sedan, an off-road vehicle, a multi-purpose vehicle (MPV), or other vehicle types. A vehicle generally includes wheels, a power source, and a transmission system disposed between the wheels and the power source. The transmission system is capable of transmitting power provided by the power source to the wheels, causing the wheels to rotate, thereby driving the vehicle.

[0042] It should be noted that in the embodiments of this application, the type of vehicle power source is not limited. For example, for a fuel-powered vehicle, the power source may refer to a gasoline engine, a diesel engine, or other fuel-powered engine; for an electric vehicle, the power source may refer to an electric motor; for a hybrid vehicle, the power source may refer to an engine or an electric motor; and for a vehicle powered by other means, the power source may refer to a device that generates power.

[0043] As described in the background, a vehicle's cooling system typically incorporates a water reservoir, which serves as both a fluid replenishment and gas-liquid separation mechanism. However, in related art, the return water from the reservoir is typically ejected, and the reservoir typically employs a two- or three-chamber structure. This results in a high concentration of bubbles in the reservoir, making it prone to incomplete gas-liquid separation. Gases in the reservoir can enter the cooling cavities of various vehicle components along with the coolant, reducing the performance of the vehicle's entire cooling system and even diminishing the durability of the components.

[0044] In light of this, embodiments of the present application provide improvements to a water storage bottle in a vehicle. The water storage bottle comprises a housing and multiple partitions disposed within the housing. Each partition defines multiple fluid chambers within the housing. The multiple fluid chambers are sequentially interconnected along the circumference of the housing and include adjacent, but not connected, return and discharge chambers. By separating a diversion chamber within the return chamber, a return port on the housing communicates with the diversion chamber, and a discharge port on the housing communicates with the discharge chamber. Cooling liquid enters the water storage bottle through the diversion chamber, flows through the sequentially interconnected fluid chambers, and then exits through the discharge chamber. Since the coolant enters the return chamber from the smaller diversion chamber, the pressure change upon entering the water storage bottle is minimized, resulting in smoother inflow and less impact on the liquid surface within the water storage bottle. Furthermore, the sequentially interconnected circumferential fluid chambers within the housing allow the coolant to flow along the circumference of the housing, increasing the coolant's flow path within the water storage bottle, prolonging the gas-liquid separation time and improving gas-liquid separation efficiency. This improves the performance of the vehicle's entire cooling system.

[0045] The water storage bottle provided in the embodiment of the present application is described in detail below.

[0046] The water storage bottle provided in the embodiment of the present application is used in the cooling system of the aforementioned vehicle. The water storage bottle is, for example, a pressurized low-temperature water storage bottle.

[0047] Figure 1 A schematic structural diagram of a water storage bottle provided in an embodiment of the present application from one perspective. Figure 2 for Figure 1 A schematic structural diagram of the water bottle from another perspective.

[0048] Reference Figure 1 and Figure 2As shown, the water bottle 10 includes a housing 100, which encloses a hollow cavity. This allows coolant to flow through the water bottle 10 and replenish the vehicle's cooling system. The housing 100 is provided with a liquid return port 111, a liquid addition port 200, and a liquid outlet 121. These ports 111, 200, and 121 all communicate with the hollow cavity within the housing 100. The liquid return port 111 and the liquid addition port 200 allow external coolant to enter the housing 100, while the liquid outlet 121 allows coolant within the housing 100 to flow out of the water bottle 10.

[0049] During normal operation of the water storage bottle 10, the coolant can enter the hollow cavity of the housing 100 through the liquid return port 111, circulate within the hollow cavity of the housing 100, and then flow out through the liquid outlet 121 of the housing 100. During this process, the coolant is blocked and drained by the internal structure of the housing 100, which can reduce the flow rate of the coolant in the water storage bottle 10 and increase the flow pressure of the coolant, thereby achieving the purpose of separating the gas in the coolant (gas-liquid separation).

[0050] When the vehicle's cooling system needs to be replenished with coolant, coolant can be replenished into the hollow cavity from the liquid filling port 200 on the shell 100. The replenished coolant flows out from the liquid outlet 121 of the shell 100 and flows into the cooling cavity of each component in the cooling system.

[0051] The opening sizes of the liquid return port 111 and the liquid outlet 121 can both be small to reduce the coolant's flow area, maintain a low coolant flow velocity within the water reservoir 10, and increase the coolant's flow time within the water reservoir 10. This allows the coolant sufficient time for gas-liquid separation within the water reservoir 10, ensuring effective gas-liquid separation and safeguarding the performance of the vehicle's cooling system.

[0052] For example, the opening size of liquid return port 111 can be slightly smaller than that of liquid outlet port 121. This allows coolant to enter housing 100 through the smaller opening of liquid return port 111, maintaining a lower flow rate within water reservoir 10. Furthermore, by increasing the opening size of liquid outlet 121, the coolant's flow rate loss within water reservoir 10 can be compensated, allowing the coolant to flow through water reservoir 10 at a more stable rate, ensuring smoother and more reliable operation of the vehicle's cooling system.

[0053] Continue to refer to Figure 1 and Figure 2The housing 100 of the water storage bottle 10 may include an upper shell 110 and a lower shell 120. The upper shell 110 and the lower shell 120 are aligned vertically and together form a hollow cavity. A sealing structure may be provided between the upper shell 110 and the lower shell 120 to seal the upper shell 110 and the lower shell 120 and ensure the sealing of the water storage bottle 10. The sealing structure may be, for example, a sealing ring, which is squeezed between the edges of the upper shell 110 and the lower shell 120 to seal the gap between the upper shell 110 and the lower shell 120.

[0054] For example, the lower shell 120 can serve as the main support structure of the housing 100. The lower shell 120 can be relatively large in size and can be a frame-like structure with a relatively high height and an open top. The upper shell 110 is mainly used to cooperate with the lower shell 120 to form a hollow cavity. The upper shell 110 can be relatively small in size and can be a cover-like structure with a relatively low height.

[0055] Figure 3 for Figure 1 An exploded structural diagram of one perspective of the water bottle in the figure. Figure 4 for Figure 1 Another perspective of the decomposition structure of the water bottle in the figure.

[0056] Reference Figure 3 and Figure 4 As shown, a plurality of partitions 300 are disposed within the housing 100 of the water storage bottle 10. These partitions 300 define a plurality of fluid chambers 400 within the hollow cavity of the housing 100. The partitions 300 can be arranged along the plane of the housing 100, and their extension direction can be inclined relative to the plane of the housing 100, so that the plurality of fluid chambers 400 formed by the partitions 300 are arranged along the plane of the housing 100. Consequently, the coolant within the water storage bottle 10 can flow along the plane of the housing 100.

[0057] For example, each partition plate 300 can extend along the height of the housing 100, and each fluid chamber 400 separated by the multiple partition plates 300 can extend along the height of the housing 100. Furthermore, the cross-sectional dimensions of the fluid chambers 400 remain consistent along the height of the housing 100. This ensures a uniform flow rate of the coolant within each fluid chamber 400 and a balanced fluid pressure. This improves the smoothness of the coolant flow, more evenly distributes the forces on the water storage bottle 10, and enhances the reliability of the water storage bottle 10.

[0058] Combine Figure 3 and Figure 4As shown, the multiple partitions 300 in the housing 100 can be composed of the structure in the upper shell 110 and the structure in the lower shell 120. The shape and structure of the multiple partitions 300 in the upper shell 110 match the shape and structure of the multiple partitions 300 in the lower shell 120.

[0059] In other words, each partition plate 300 may include an upper plate portion 301 and a lower plate portion 302. The upper plate portion 301 of each partition plate 300 may be disposed within the upper shell 110, for example, the upper plate portion 301 of each partition plate 300 may be integrally formed within the upper shell 110. The lower plate portion 302 of each partition plate 300 may be disposed within the lower shell 120, for example, the lower plate portion 302 of each partition plate 300 may be integrally formed within the lower shell 120. The upper shell 110 and the lower shell 120 are aligned vertically so that the upper plate portion 301 and the lower plate portion 302 of each partition plate 300 are aligned to form a complete partition plate 300. For example, the upper plate portion 301 and the lower plate portion 302 of each partition plate may both extend along the height direction of the shell 100.

[0060] In this embodiment, the fluid chambers 400 formed by the plurality of partitions can be sequentially connected along the circumference of the shell 100. The plurality of fluid chambers 400 can include a liquid return chamber 410 and a liquid outlet chamber 420. The liquid return chamber 410 and the liquid outlet chamber 420 are arranged adjacent to each other, and the liquid return chamber 410 and the liquid outlet chamber 420 are not connected. In addition, the plurality of fluid chambers 400 also include a diversion chamber 430 separated from the liquid return chamber 410. In other words, a partition plate 300 is further provided in the liquid return chamber 410, and the partition plate 300 separates a small space from the liquid return chamber 410 to form the diversion chamber 430. The diversion chamber 430 is connected to the liquid return chamber 410.

[0061] The liquid return port 111 on the housing 100 can be provided corresponding to the diversion cavity 430, and the liquid return port 111 is connected to the diversion cavity 430. The liquid outlet port 121 on the housing 100 can be provided corresponding to the liquid outlet cavity 420, and the liquid outlet port 121 is connected to the liquid outlet cavity 420. The coolant flowing into the water storage bottle 10 from the liquid return port 111 enters the liquid return cavity 410 through the diversion cavity 430, flows through the sequentially connected fluid cavities 400, and finally flows from the liquid outlet cavity 420 into the liquid outlet port 121, and is discharged from the water storage bottle 10 through the liquid outlet port 121.

[0062] On the one hand, by separating the diversion chamber 430 from the liquid return chamber 410, the diversion chamber 430 only occupies a portion of the liquid return chamber 410, resulting in a very small volume. Thus, when the coolant enters the small diversion chamber 430 from the liquid return port 111, the pressure fluctuations of the coolant entering the water storage bottle 10 are minimal, resulting in a smoother inflow of the coolant into the water storage bottle 10 and minimal changes in the inflow speed. This reduces the impact of the coolant entering the water storage bottle 10 on the coolant level within the water storage bottle 10, preventing the inflow of the coolant from spurting into the water storage bottle 10. Consequently, the gas content in the coolant within the water storage bottle 10 can be reduced.

[0063] On the other hand, a plurality of fluid chambers 400 arranged along the plane of the shell 100 are separated by the partition plate 300 within the shell 100, and the fluid chambers 400 are sequentially connected in the circumferential direction of the shell 100. The adjacent return liquid chamber 410 and the liquid outlet chamber 420 are not connected, with the return liquid chamber 410 serving as the starting chamber and the liquid outlet chamber 420 serving as the ending chamber. The coolant enters the return liquid chamber 410 from the guide chamber 430, flows from the return liquid chamber 410 along the sequentially connected fluid chambers 400, and finally flows to the liquid outlet chamber 420 and flows out from the liquid outlet 121. With this arrangement, the coolant flows from the return liquid chamber 410 through the fluid chambers 400 in sequence, and finally flows out from the liquid outlet chamber 420 adjacent to the return liquid chamber 410. This allows the coolant to flow circumferentially within the water storage bottle 10, allowing the coolant to circumferentially circulate around the water storage bottle 10. In this way, the flow distance of the coolant in the water storage bottle 10 is increased, the gas-liquid separation time of the coolant in the water storage bottle 10 can be prolonged, and the gas-liquid separation efficiency of the water storage bottle 10 is improved.

[0064] The water bottle 10 in this embodiment not only adds a small flow guide cavity 430 within the housing 100, but also connects the multiple fluid cavities 400 separated by the partition plate 300 in sequence along the circumference of the housing 100, thereby increasing the coolant's flow path within the water bottle 10. This reduces the gas content of the coolant within the water bottle 10 while also extending the gas-liquid separation time and improving the gas-liquid separation efficiency of the water bottle 10. This significantly reduces the gas content in the coolant and enables more thorough gas separation, thereby improving the performance of the vehicle's entire cooling system and enhancing the durability of its components.

[0065] Continue to refer to Figure 3 and Figure 4 The partition plates 300 in the housing 100 include a plurality of first partition plates 310 sequentially arranged along the circumference of the housing 100. Each first partition plate 310 can separate a plurality of fluid chambers 400 sequentially arranged along the circumference of the housing 100. The fluid chambers 400 separated by the plurality of first partition plates 310 can be sequentially connected along the circumference of the housing 100 to enable the coolant to flow along the circumference of the housing 100.

[0066] Each first baffle 310 may extend from the inner sidewall of the housing 100 toward the center of the housing 100, and each first baffle 310 may be spaced apart along the inner sidewall of the housing 100. In this way, a plurality of fluid cavities 400 sequentially arranged along the circumference of the housing 100 may be formed by the first baffles 310.

[0067] The multiple fluid chambers 400 separated by the multiple first partitions 310 may include the aforementioned liquid return chamber 410 and liquid outlet chamber 420. The liquid return chamber 410 and the liquid outlet chamber 420 may be located on both sides of one of the first partitions 310. In this way, the liquid return chamber 410 and the liquid outlet chamber 420 both extend to the inner sidewall of the shell 100, and the liquid return chamber 410 and the liquid outlet chamber 420 are arranged adjacent to each other. A partition plate 300 may be provided in the liquid return chamber 410 at a location corresponding to the reflux port, so that the diversion chamber 430 separated in the liquid return chamber 410 is located in the primary groove where the inner sidewall of the shell 100 is located, and the liquid return chamber 410 is connected to the reflux port. The liquid outlet 121 may be provided on the sidewall of the shell 100 corresponding to the area where the liquid outlet chamber 420 is located, so that the liquid outlet chamber 420 is connected to the liquid outlet 121.

[0068] For ease of description, in this embodiment, the partition plate 300 that encloses the diversion chamber 430 is defined as the diversion partition plate 330. In other words, by disposing the diversion partition plate 330 within the liquid return chamber 410, the cavity enclosed by the diversion partition plate 330 becomes the diversion chamber 430. By providing an opening in the diversion partition plate 330, the diversion chamber 430 is connected to the liquid return chamber 410.

[0069] Continue to refer to Figure 3 and Figure 4 The partition plates 300 in the housing 100 may further include a second partition plate 320. The second partition plate 320 may be an annular partition plate and may be located in the middle region of the housing 100 in the plane direction. Each of the first partition plates 310 may be connected to the outer sidewall of the second partition plate 320. In other words, one end of each of the first partition plates 310 is connected to the inner sidewall of the housing 100, and the other end of each of the first partition plates 310 is connected to the outer sidewall of the second partition plate 320.

[0070] The combined action of the first and second partitions 310 and 320 creates a plurality of fluid chambers 400 sequentially arranged along the circumference of the housing 100, as well as a fluid chamber 400 located in the middle region of the housing 100. In this case, among the plurality of fluid chambers 400 sequentially arranged along the circumference of the housing 100, with the exception of the adjacent return chamber 410 and the adjacent discharge chamber 420, two adjacent fluid chambers 400 may be disconnected from each other along the coolant flow path. Both of these adjacent fluid chambers 400 may be connected to the fluid chamber 400 enclosed by the second partitions 320. This allows the coolant to flow sequentially through all of the fluid chambers 400, including the fluid chamber 400 enclosed by the second partitions 320.

[0071] By adding a second partition 320 to the first partition 310, the housing 100 is divided into multiple fluid chambers 400 arranged sequentially along the circumference, and a further fluid chamber 400 is formed in the central region of the housing 100. This arrangement allows the coolant to flow not only through the fluid chambers 400 arranged sequentially along the circumference of the housing 100, but also through the fluid chamber 400 located in the central region of the housing 100. This increases the coolant's flow path within the water storage bottle 10, prolonging the gas-liquid separation time during the coolant's flow within the water storage bottle 10 and improving the gas-liquid separation efficiency of the water storage bottle 10.

[0072] Exemplarily, the second partition 320 can be a circular ring structure, or in other words, the second partition 320 is in the shape of a hollow cylinder. Thus, the second partition 320 has no corners, and the coolant flows more smoothly and orderly within the fluid cavity 400 enclosed by the second partition 320, without causing coolant eddies or turbulence, or problems such as liquid surface slapping or collisions, thereby helping to reduce the generation of bubbles in the coolant. Furthermore, the outer wall of the second partition 320, the first partition 310, and the inner wall of the housing 100 together enclose the fluid cavity 400, and the outer wall of the second partition 320 is in the shape of an arc plate within the fluid cavity 400, which guides the flow of coolant within the fluid cavity 400 and also allows the coolant to flow more smoothly and orderly within the fluid cavity 400.

[0073] On this basis, taking the shell 100 as a cube or rectangular structure as an example, the four corners of the shell 100 can also be designed with arc transitions to improve the smoothness of the fluid cavity 400 surrounded by the inner wall of the shell 100, the first partition 310 and the second partition 320, so that the flow of the coolant in these fluid cavities 400 is smoother and more orderly.

[0074] At least four first baffles 310 can be sequentially spaced along the circumference of the housing 100. These at least four first baffles 310 can separate at least four fluid chambers 400 sequentially arranged along the circumference of the housing 100. Together with the guide chamber 430 and the fluid chamber 400 located in the middle region of the housing 100, at least six fluid chambers 400 can be separated within the housing 100. This increases the number of fluid chambers 400 within the housing 100, extending the coolant flow path within the housing 100, prolonging the gas-liquid separation time, and improving the gas-liquid separation efficiency.

[0075] For example, the central axis of the second partition 320 located in the middle region of the housing 100 can coincide with the centerline of the housing 100. In other words, the second partition 320 is located in the central region of the housing 100. The first partitions 310 can be evenly spaced along the circumference of the second partition 320, and the fluid cavities 400 separated by the first partitions 310 are of comparable size. This ensures a more balanced flow rate and pressure of the coolant within each fluid cavity 400, improving the gas-liquid separation effect of the water bottle 10, and evenly balancing the forces applied to the entire water bottle 10, thereby increasing the reliability of the water bottle 10.

[0076] by Figure 3 and Figure 4 As shown in the example, four first baffles 310 are sequentially spaced along the circumference of the housing 100, and a second baffle 320 is connected to the centers of the four first baffles 310. The four first baffles 310 and the second baffle 320 separate and form five larger fluid chambers 400 within the housing 100, wherein two adjacent fluid chambers 400 on either side of one first baffle 310 serve as a return liquid chamber 410 and a liquid outlet chamber 420, respectively. In addition to the guide chamber 430 separated from the return liquid chamber 410, a total of six fluid chambers 400 are formed within the housing 100. The coolant flows through these six fluid chambers 400 in sequence, increasing the flow path of the coolant within the housing 100 and prolonging the gas-liquid separation time of the coolant.

[0077] Taking the housing 100 as a rectangular parallelepiped structure as an example, when four first partitions 310 are arranged circumferentially spaced apart on the housing 100, two of the four first partitions 310 are arranged opposite each other and located on the centerline of the length direction of the housing 100, and the other two first partitions 310 are arranged opposite each other and located on the centerline of the width direction of the housing 100. The intersection of the extended lines of the four first partitions 310 can be located on the centerline of the housing 100.

[0078] In other examples, more than five first partitions 310 may be sequentially spaced apart along the circumference of the housing 100. For example, the number of first partitions 310 may be five, six, or seven. In this way, the number of fluid cavities 400 formed within the housing 100 may reach seven or more. For example, seven fluid cavities 400, eight fluid cavities 400, or nine fluid cavities 400 may be formed within the housing 100. This is not a limitation in the present embodiment.

[0079] It should be noted that the number of fluid cavities 400 formed in the housing 100 should not be too large, or in other words, the number of first partitions 310 spaced circumferentially within the housing 100 should not be too large. This is to prevent the partitions 300 from affecting the flow rate of the coolant in the housing 100, ensuring that the coolant flows through the water storage bottle 10 at an appropriate flow rate.

[0080] Figure 5 for Figure 1 Schematic diagram of the structure of the lower shell of the water bottle. Figure 6 for Figure 1 Schematic diagram of the structure of the upper shell of the water storage bottle. Figure 5 and Figure 6 As shown, as for the guide cavity 430 separated from the liquid return cavity 410, the guide cavity 430 can extend from the top of the housing 100 to the bottom of the housing 100, and the liquid return port 111 can be connected to the upper part of the guide cavity 430 (see Figure 6 ), the bottom of the diversion cavity 430 can be connected to the bottom of the liquid return cavity 410 (see Figure 5 That is, the guide baffle 330 extends from the top of the housing 100 to the bottom of the housing 100 , and the bottom of the guide baffle 330 is open to achieve communication between the bottom of the guide cavity 430 and the bottom of the liquid return cavity 410 .

[0081] With this arrangement, coolant entering through the return liquid port 111 flows from the upper portion of the diversion cavity 430 to the lower portion, and then flows out of the bottom of the diversion cavity 430 into the return liquid cavity 410. The walls of the diversion cavity 430 limit the flow range of the coolant and guide the flow direction of the coolant, thereby preventing the coolant from being sprayed when entering the housing 100 and allowing the coolant to flow more smoothly and orderly from the diversion cavity 430 into the return liquid cavity 410. This prevents the formation of bubbles when the coolant enters the housing 100, reduces the bubble content in the coolant, ensures the performance of the entire vehicle cooling system, and improves the durability of the components in the cooling system.

[0082] Reference Figure 5As shown, the diversion chamber 430 can be connected to the partition plate 300 between the liquid return chamber 410 and the liquid outlet chamber 420. In other words, the diversion partition plate 330 can be connected to the partition plate 300 between the liquid return chamber 410 and the liquid outlet chamber 420. Since the diversion chamber 430 needs to be connected to the liquid return port 111 on the side wall of the shell 100, the diversion chamber 430 can be connected to the partition plate 300 and the inner side wall of the shell 100. The diversion chamber 430 can be surrounded by the partition plate 300, the inner side wall of the shell 100, and the diversion partition plate 330. By opening an opening at the bottom of the diversion partition plate 330, the diversion chamber 430 is connected to the liquid return chamber 410.

[0083] In this way, the coolant flows into the housing 100 from the side of the return chamber 410 near the outlet chamber 420, circulates once within the housing 100, and then flows out of the outlet chamber 420. Since the coolant's starting and ending points within the housing 100 are connected, the coolant's flow path within the housing 100 is longer, further facilitating gas-liquid separation. This more thorough gas-liquid separation in the water storage bottle 10 improves the performance of the vehicle's entire cooling system.

[0084] Continue to refer to Figure 5 As shown, as to the sequential communication between the fluid cavities 400 in the direction of coolant flow, drainage holes 340 may be provided on the partition plate 300 between adjacent fluid cavities 400. Adjacent fluid cavities 400 are connected through the drainage holes 340, thereby enabling the coolant to flow through the sequentially arranged fluid cavities 400. For example, the drainage holes 340 may be provided near the bottom of the fluid cavity 400 to allow the coolant to flow along the bottom of the fluid cavity 400, thereby avoiding a significant height difference when the coolant enters the fluid cavity 400 and thereby preventing the increase of bubbles in the coolant.

[0085] The first partition 310 between the return liquid chamber 410 and the outlet liquid chamber 420 may not be provided with the drainage hole 340, so that the return liquid chamber 410 and the outlet liquid chamber 420 are not connected. As previously mentioned, when the housing 100 is provided with a fluid chamber 400 surrounded by the second partition 320, in addition to the return liquid chamber 410 and the outlet liquid chamber 420 being disconnected, two adjacent fluid chambers 400 arranged in sequence along the circumferential direction may be disconnected in the coolant flow path, and the first partition 310 between the two fluid chambers 400 may not be provided with the drainage hole 340. The portions of the second partition 320 corresponding to the two fluid chambers 400 are both provided with the drainage hole 340, so that the two fluid chambers 400 are connected to the fluid chamber 400 surrounded by the second partition 320.

[0086] by Figure 5As shown in the example, in the circumferential direction of the shell 100, no drainage hole 340 is set on the first partition 310 between the liquid outlet cavity 420 and the fluid cavity 400 located on the other side thereof (the side opposite to the return liquid cavity 410), and the liquid outlet cavity 420 and the fluid cavity 400 are both connected to the fluid cavity 400 surrounded by the second partition 320 in the middle through the drainage hole 340.

[0087] As the coolant flows within the housing 100, its velocity gradually decreases due to the resistance of the partitions 300 between adjacent fluid cavities 400, the inner wall of the housing 100, and the viscosity of the coolant itself. To ensure smooth and steady coolant flow within the housing 100, the opening area of each drainage hole 340 on the partitions 300 between the fluid cavities 400 can be gradually increased along the flow direction of the coolant. This gradually increases the flow area of the coolant, compensating for any loss in coolant velocity and ensuring a more uniform flow rate within the housing 100.

[0088] Reference Figure 6 As shown, at least a portion of the fluid cavity 400 within the housing 100 can be provided with a vent 350. The vent 350 can be provided in the upper portion of the housing 100, for example, the vent 350 can be provided in the upper shell 110. Gas within the housing 100 can be discharged through the vent 350 to ensure gas-liquid separation of the coolant. For example, each vent 350 can be connected to the liquid filling port 200 on the housing 100, and the gas within the housing 100 can be discharged through the liquid filling port 200.
