Description

Technical Field

[0001] The invention relates to the technical field of heat exchange, and in particular to an electrolyte flow storage tank with a cooling function. Background Art

[0002] In the existing electrolyte cooling technology, most systems use pipeline heat exchange to achieve electrolyte cooling. This method mainly introduces the electrolyte into an independent heat exchanger, uses a cooling medium (such as water) to exchange heat with the electrolyte through the pipeline, thereby taking away the heat in the electrolyte and achieving a cooling effect.

[0003] However, since the heat exchanger and the liquid storage tank are usually split designs, the overall structure of the cooling system is complicated. For example, the non-integrated design leads to low integration and occupies more space, which limits the compactness and flexibility of the overall structure and makes it difficult to adapt to space constraints in certain application scenarios. Summary of the invention

[0004] In view of this, the present invention provides an electrolyte flow storage tank with a cooling function to solve the problem of low integration caused by the separate design of the heat exchanger and the storage tank.

[0005] Specifically, the present invention provides an electrolyte flow storage tank with a cooling function, comprising a tank side wall, wherein the tank side wall is provided with at least one first fluid channel, one end of any first fluid channel is located at one of the top and bottom of the tank side wall, and one end of any first fluid channel is connected to a liquid inlet main pipe as a branch liquid inlet, the other end of any first fluid channel extends toward the other of the top and bottom of the tank side wall, and the other end of any first fluid channel is connected to a liquid outlet main pipe as a branch liquid outlet, and the first fluid channel is used for the flow of heat exchange medium.

[0006] Beneficial effects: By directly opening the first fluid channel on the side wall of the tank body, the heat exchange medium can circulate in the side wall of the tank body, ensuring sufficient contact between the electrolyte and the heat exchange medium, thereby improving the heat exchange efficiency. When the temperature of the electrolyte in the tank body rises, the heat exchange medium can effectively absorb and take away excess heat, thereby keeping the electrolyte within a suitable temperature range; at the same time, by opening the first fluid channel for the heat exchange medium to flow in the side wall of the tank body, there is no need to add an additional heat exchanger as in conventional solutions, thereby saving space and making the layout of the entire structure more compact.

[0007] In an optional embodiment, the electrolyte flow storage tank with a cooling function also includes a tank top plate group and a tank bottom plate group, wherein the tank top plate group is located at the top of the tank side wall; the tank bottom plate group is located at the bottom of the tank side wall; wherein the tank top plate group, the tank bottom plate group and the tank side wall are enclosed to form a liquid storage chamber, and in the tank top plate group and the tank bottom plate group, one of the two is provided with a buffer chamber, the buffer chamber is arranged adjacent to the liquid inlet main pipe along the axial direction of the central axis of the tank side wall and the buffer chamber is connected to the liquid inlet main pipe, and the branch liquid inlet connects the buffer chamber with the first fluid channel; the other is provided with a liquid collecting chamber, the liquid collecting chamber is arranged adjacent to the liquid outlet main pipe along the axial direction of the central axis of the tank side wall and the liquid collecting chamber is connected to the liquid outlet main pipe, and the branch liquid outlet connects the first fluid channel with the liquid outlet main pipe.

[0008] Beneficial effect: by providing a buffer chamber in one of the top plate group and the bottom plate group of the tank body, and making the buffer chamber adjacent to and connected to the liquid inlet main pipe, it is ensured that the heat exchange medium can enter the buffer chamber at the liquid inlet main pipe for buffering, so that the heat exchange medium in the buffer chamber can flow into each first fluid channel more evenly, avoiding local overheating or uneven temperature of the tank body during the heat exchange process, thereby further improving the heat exchange efficiency; and by providing a liquid collecting chamber in the other of the top plate group and the bottom plate group of the tank body, and making the liquid collecting chamber connected to the liquid outlet main pipe, it is helpful to collect the heat exchange medium flowing out of each first fluid channel, ensuring that the heat is fully taken away and flows out at the liquid outlet main pipe, so that the heat exchange medium can be smoothly discharged from the tank body after sufficient heat exchange; at the same time, through the arrangement of the buffer chamber and the liquid collecting chamber, the tank body as a whole can be made more compact, further improving the integration of the tank body, and facilitating sampling and detection of the heat exchange medium at the buffer chamber and the liquid collecting chamber.

[0009] In an optional embodiment, the tank body top plate group includes a first top wall middle portion and a first top wall peripheral portion, the first top wall middle portion is arched relative to the first top wall peripheral portion, and the height gradually decreases in the direction extending from the first top wall middle portion to the first top wall peripheral portion; the tank body top plate group also includes a second top wall middle portion and a second top wall peripheral portion, the second top wall middle portion is recessed relative to the second top wall peripheral portion, and the height gradually increases in the direction extending from the second top wall middle portion to the second top wall peripheral portion; wherein, the first top wall middle portion, the first top wall peripheral portion, the second top wall middle portion and the second top wall peripheral portion present a shuttle-shaped structure.

[0010] Beneficial effect: By making the middle part of the first top wall, the peripheral part of the first top wall, the middle part of the second top wall and the peripheral part of the second top wall into a limited shuttle-shaped structure, when the heat exchange medium enters the buffer chamber at the liquid inlet main pipe, the heat exchange medium accumulates continuously, so that the liquid level of the heat exchange medium gradually rises. That is, compared with the solution in which the heat exchange medium directly enters the first fluid channel, this structure can reduce the power of the heat exchange medium, so that the heat exchange medium enters each first fluid channel more evenly and smoothly, thereby further improving the heat exchange efficiency.

[0011] In an optional embodiment, when the height of the buffer chamber is higher than the height of the liquid outlet main pipe, the top of the tank side wall is divided into at least a first area and a second area, the first area is connected to the peripheral part of the second top wall, the height of the second area is higher than the height of the first area, and the second area is connected to the peripheral part of the first top wall.

[0012] Beneficial effect: By making the height of the buffer chamber higher than the height of the liquid outlet main pipe, and making the buffer chamber and the liquid inlet main pipe both arranged above the liquid outlet main pipe, the heat exchange medium at the front end entering the buffer chamber enters the buffer chamber under the action of its own gravity and the heat exchange medium at the rear end, and by connecting the first area with the peripheral part of the second top wall, and the second area with the peripheral part of the first top wall, a closed chamber is formed, so that the heat exchange medium entering the buffer chamber can gradually flow to the branch liquid inlet as the liquid level rises, and then flow into the first fluid channel. That is, in the process of slowly raising the liquid level of the heat exchange medium entering the buffer chamber, the heat exchange medium is prevented from directly entering the first fluid channel without slowing down, which helps to reduce the turbulence and eddy current of the heat exchange medium in the buffer chamber, so that the heat exchange medium can enter each first fluid channel more evenly and smoothly, thereby improving the heat exchange efficiency.

[0013] In an optional embodiment, the side wall of the tank body is further provided with at least one second fluid channel, one end of the second fluid channel serves as a branch air outlet and is connected to the buffer chamber, and the other end of the second fluid channel serves as a branch air inlet and is connected to the liquid collection chamber.

[0014] Beneficial effect: By adding at least one second fluid channel to the side wall of the tank body and connecting the buffer chamber and the liquid collecting chamber through the second fluid channel, the air in the first fluid channel, the liquid collecting chamber and the second fluid channel can be continuously discharged to the buffer chamber during the process of the heat exchange medium entering the first fluid channel; at the same time, it helps to separate the air and the heat exchange medium, and during the initial entry of the heat exchange medium into the buffer chamber, the interference of air accumulation or poor discharge in the buffer chamber on the heat exchange medium entering the buffer chamber is reduced, which helps the heat exchange medium to enter the buffer chamber smoothly; in addition, by integrating the second fluid channel, a compact layout can be formed, which further saves space and improves the overall integration of the tank body.

[0015] In an optional embodiment, the electrolyte flow storage tank with cooling function also includes a branch gas outlet, the gas outlet channel of the branch gas outlet is connected to the branch gas outlet, and the height of the gas outlet of the branch gas outlet is higher than the height of the branch liquid inlet.

[0016] Beneficial effect: The arrangement of the branch air outlet piece helps to raise the air outlet height of the air discharged from the second fluid channel to the buffer chamber, thereby preventing the heat exchange medium in the buffer chamber from simultaneously entering the branch liquid inlet and the branch air outlet during the process of rising liquid level. That is, the degree of interference between the process of the heat exchange medium flowing into the buffer chamber and the air discharged to the outside can be reduced, so that in the process of the heat exchange medium entering the branch liquid inlet, air is allowed to continuously enter the buffer chamber at the branch air outlet piece, thereby improving the efficiency of the heat exchange medium entering the branch liquid inlet and improving the efficiency of air discharge.

[0017] In an optional embodiment, the electrolyte flow storage tank with a cooling function further includes a ventilation main pipe, and the ventilation main pipe is centrally installed in the middle part of the first top wall.

[0018] Beneficial effect: By installing the additional ventilation main pipe in the middle part of the first top wall, it is helpful to discharge the air evenly and efficiently, reduce the impact of air on the heat exchange medium entering the first fluid channel, ensure that the heat exchange medium enters the first fluid channel efficiently, thereby ensuring that the electrolyte temperature distribution inside the liquid storage tank is more uniform, and improving the cooling effect.

[0019] In an optional embodiment, the liquid inlet main pipe is installed in the radial direction of the central axis of the tank side wall and is spaced apart from the ventilation main pipe.

[0020] Beneficial effect: By arranging the liquid inlet main pipe and the ventilation main pipe at intervals in the radial direction of the central axis of the side wall of the tank body, and since the ventilation main pipe is installed in the middle part of the first top wall, the height of the liquid inlet of the liquid inlet main pipe entering the buffer chamber will be lower than the height of the air outlet of the ventilation main pipe entering the buffer chamber, thereby reducing the interference degree of the two processes of heat exchange medium inlet and air outlet, which helps to quickly discharge the air to improve the air discharge efficiency.

[0021] In an optional embodiment, any one of the first fluid channels extends continuously along the circumferential direction of the central axis of the side wall of the tank body and the axial direction of the central axis of the side wall of the tank body to present a spiral shape.

[0022] Beneficial effect: By making the first fluid channel into a spiral shape, the flow rate of the heat exchange medium is reduced, which helps to increase the heat exchange time between the heat exchange medium and the electrolyte, thereby enhancing the heat exchange efficiency, so that the heat exchange medium and the electrolyte can fully exchange heat. At the same time, facilities with lower parameters (such as power) can be used to achieve the same cooling effect, thereby reducing energy consumption and saving energy costs.

[0023] In an optional embodiment, the liquid outlet main pipes are provided in plurality, and the plurality of liquid outlet main pipes are arranged at intervals along the circumferential direction of the central axis of the side wall of the tank body.

[0024] Beneficial effect: By providing multiple liquid outlet main pipes and arranging the multiple liquid outlet main pipes at intervals in the circumferential direction of the central axis of the tank side wall, it is helpful to discharge the heat exchange medium in time, and the efficiency of discharging the heat exchange medium in the liquid collecting chamber can be improved; at the same time, it helps to flexibly adjust and optimize when facing different working conditions or needs to meet actual needs.

[0042] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0043] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0044] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0045] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0046] In conventional technology, the heat exchanger and the liquid storage tank are usually split designs. The electrolyte, such as vanadium liquid, is introduced into an independent heat exchanger, and a cooling medium (such as water or air) is used to exchange heat with the electrolyte through pipes, thereby taking away the heat in the electrolyte. With this arrangement, the electrolyte needs to circulate between the liquid storage tank and the heat exchanger. However, the connection components and the length of the pipeline will be increased, which not only increases the manufacturing cost of the system, but also increases the potential risk of leakage. At the same time, the non-integrated design leads to a low degree of integration and occupies more space, which limits the compactness and flexibility of the overall structure, making it difficult to adapt to space constraints in certain application scenarios.

[0047] To this end, the present invention directly adds a channel for the flow of heat exchange medium and a channel for exhaust gas on the side wall of the liquid storage tank to improve the overall integration and reduce the length of connecting components and pipelines, thereby improving the electrolyte leakage phenomenon.

[0048] Combine the following Figures 1 to 7 , describing an embodiment of the present invention.

[0049] like Figure 1 As shown, the present invention provides an electrolyte flow storage tank with a cooling function, comprising a tank side wall 1. The tank side wall 1 is provided with a first fluid channel 2 extending between the tank top and the tank bottom.

[0050] It can be explained that there is no specific limitation on the number of the first fluid channels 2, and the number may be one, two or more.

[0051] At this time, one end of any first fluid channel 2 is located at one of the top and bottom of the tank side wall 1, and is connected to the liquid inlet main pipe 31 as a branch liquid inlet 21. The other end of any first fluid channel 2 extends toward the other of the top and bottom of the tank side wall 1, and is connected to the liquid outlet main pipe 32 as a branch liquid outlet 22. The first fluid channel 2 is used for the flow of heat exchange medium.

[0052] Therefore, by directly opening the first fluid channel 2 in the side wall 1 of the tank body, the heat exchange medium can circulate in the side wall 1 of the tank body, ensuring sufficient contact between the electrolyte and the heat exchange medium, thereby improving the heat exchange efficiency. When the temperature of the electrolyte in the tank body rises, the heat exchange medium can effectively absorb and take away excess heat, thereby keeping the electrolyte within a suitable temperature range.

[0053] At the same time, by opening a first fluid channel 2 for the flow of heat exchange medium on the side wall 1 of the tank body, there is no need to add an additional heat exchanger as in the conventional solution, thereby saving space, making the layout of the entire structure more compact, and avoiding the electrolyte from being led out of the tank, reducing the number of connecting parts, reducing the complexity of the overall structure and the potential risk of leakage, and simplifying the installation and maintenance processes, thereby improving the reliability and durability of the overall structure.

[0054] In addition, since the first fluid channel 2 extends between the top and the bottom of the tank side wall 1, it helps to avoid heat accumulation.

[0055] It can be explained that, in the present embodiment, the liquid storage chamber 6 for storing the electrolyte formed by the side wall 1 of the tank body is in a columnar or conical shape.

[0056] Preferably, the tank side wall 1 encloses a cylindrical liquid storage chamber 6 .

[0057] like Figure 1 , Figures 3 to 5 As shown, the electrolyte flow storage tank with cooling function also includes a tank top plate group 4 and a tank bottom plate group 5. The tank top plate group 4 is located at the top of the tank side wall 1; the tank bottom plate group 5 is located at the bottom of the tank side wall 1.

[0058] It can be explained that, in the present embodiment, the tank top plate group 4, the tank bottom plate group 5 and the tank side wall 1 are enclosed to form a liquid storage chamber 6, and in the tank top plate group 4 and the tank bottom plate group 5, one of the two is provided with a buffer chamber 41, the buffer chamber 41 is arranged adjacent to the liquid inlet main pipe 31 along the axial direction of the central axis of the tank side wall 1 and the buffer chamber 41 is connected to the liquid inlet main pipe 31, and the branch liquid inlet 21 connects the buffer chamber 41 with the first fluid channel 2.

[0059] The other one of them is provided with a liquid collecting chamber 51, which is arranged adjacent to the liquid outlet main pipe 32 along the axial direction of the central axis of the tank side wall 1 and is connected to the liquid outlet main pipe 32, and the branch liquid outlet 22 connects the first fluid channel 2 with the liquid outlet main pipe 32.

[0060] In this way, by providing a buffer chamber 41 in one of the top plate group 4 and the bottom plate group 5 of the tank body, and making the buffer chamber 41 adjacent to and connected with the liquid inlet main pipe 31, it is ensured that the heat exchange medium can enter the buffer chamber 41 at the liquid inlet main pipe 31 for buffering, so that the heat exchange medium in the buffer chamber 41 can flow into each first fluid channel 2 more evenly, avoiding local overheating or uneven temperature of the tank body during the heat exchange process, thereby further improving the heat exchange efficiency.

[0061] Furthermore, by providing a liquid collecting chamber 51 in both the top plate group 4 and the bottom plate group 5 of the tank body, and connecting the liquid collecting chamber 51 with the liquid outlet main pipe 32, it is helpful to collect the heat exchange medium flowing out of each first fluid channel 2, ensure that the heat is fully taken away and flows out at the liquid outlet main pipe 32, and realize that the heat exchange medium is smoothly discharged from the tank body after sufficient heat exchange.

[0062] At the same time, by setting up the buffer chamber 41 and the liquid collecting chamber 51, the tank body as a whole can be made more compact, further improving the integration of the tank body, and facilitating operations such as sampling and testing of the heat exchange medium in the buffer chamber 41 and the liquid collecting chamber 51.

[0063] Preferably, the buffer chamber 41 is arranged at the top plate group 4 of the tank body, and the liquid collecting chamber 51 is arranged at the bottom plate group 5 of the tank body.

[0064] It can be explained that, in the present application, there is no specific limitation on the shape of the liquid collecting chamber 51. It can be any of annular, cylindrical or spiral.

[0065] It can be explained that, in this embodiment, the connection between the tank top plate group 4, the tank side wall 1 and the tank bottom plate group 5 is achieved by welding or integral molding.

[0066] It can be explained that in the above embodiment, the tank top plate group 4 includes two top plates, which are defined as an upper top plate and a lower top plate respectively. At this time, the upper top plate and the lower top plate are spaced apart in the height direction (or the central axis direction of the tank side wall 1).

[0067] Among them, the upper top plate and the lower top plate include at least one bent top plate.

[0068] That is, at least one of the upper top plate and the lower top plate of the tank top plate group 4 is set as a bent top plate.

[0069] For example, Figure 1 , Figure 3 and Figure 5 As shown, the upper top plate of the tank top plate group 4 is a flat plate, and the lower top plate is a bent top plate.

[0070] Of course, it can also be set as follows: the tank top plate group 4 includes a first top wall middle part 42 and a first top wall peripheral part 43, the first top wall middle part 42 is arched relative to the first top wall peripheral part 43, and the height gradually decreases in the direction from the first top wall middle part 42 to the first top wall peripheral part 43; the tank top plate group 4 also includes a second top wall middle part 44 and a second top wall peripheral part 45, the second top wall middle part 44 is recessed relative to the second top wall peripheral part 45, and the height gradually increases in the direction from the second top wall middle part 44 to the second top wall peripheral part 45. So that the first top wall middle part 42, the first top wall peripheral part 43, the second top wall middle part 44 and the second top wall peripheral part 45 present a shuttle-shaped structure.

[0071] In this way, by making the middle part 42 of the first top wall, the peripheral part 43 of the first top wall, the middle part 44 of the second top wall and the peripheral part 45 of the second top wall present a limited shuttle structure, when the heat exchange medium enters the buffer chamber 41 at the liquid inlet main pipe 31, the heat exchange medium accumulates continuously, so that the liquid level of the heat exchange medium gradually rises. That is, compared with the solution in which the heat exchange medium directly enters the first fluid channel 2, this structure can reduce the power of the heat exchange medium, so that the heat exchange medium enters each first fluid channel 2 more evenly and smoothly, thereby further improving the heat exchange efficiency.

[0072] In addition, the shuttle-shaped structure helps to guide the air flow to the ventilation main pipe 33, thereby improving the air discharge efficiency.

[0073] It should be noted that the specific location of the buffer chamber 41 is not specifically limited, and it can be set at the top of the tank body or at the bottom of the tank body.

[0074] Preferably, if Figure 1 , Figure 3 , Figure 5 and Figure 6As shown, the buffer chamber 41 is arranged on the top of the tank body. That is, the height of the buffer chamber 41 is higher than the height of the liquid outlet main pipe 32 at this time.

[0075] Furthermore, in order to increase the volume of the buffer chamber, the top of the tank side wall 1 is divided into at least a first area 11 and a second area 12, the first area 11 is connected to the second top wall peripheral portion 45, such as by welding or integral molding, the height of the second area 12 is higher than the height of the first area 11, and the second area 12 is connected to the first top wall peripheral portion 43, such as by welding or integral molding.

[0076] In this way, by making the height of the buffer chamber 41 higher than the height of the liquid outlet main pipe 32, the buffer chamber 41 and the liquid inlet main pipe 31 are both arranged above the liquid outlet main pipe 32, so that the heat exchange medium at the front end entering the buffer chamber 41 enters the buffer chamber 41 under the action of its own gravity and the heat exchange medium at the rear end, and by connecting the first area 11 with the peripheral part 45 of the second top wall, and the second area 12 with the peripheral part 43 of the first top wall, a closed chamber is formed, so that the heat exchange medium entering the buffer chamber 41 can gradually flow to the branch liquid inlet 21 as the liquid level rises, and then flow into the first fluid channel 2.

[0077] That is, in the process of slowly raising the liquid level of the heat exchange medium entering the buffer chamber 41, the heat exchange medium is prevented from directly entering the first fluid channel 2 without slowing down, which helps to reduce the turbulence and eddy current of the heat exchange medium in the buffer chamber 41, so that the heat exchange medium can enter each first fluid channel 2 more evenly and smoothly, thereby improving the heat exchange efficiency.

[0078] In the present application, an independent channel for exhausting air is also provided.

[0079] Specifically, if Figures 1 to 7 As shown, the tank side wall 1 is further provided with at least one second fluid channel 7 , one end of the second fluid channel 7 serves as a branch air outlet and is connected to the buffer chamber 41 , and the other end of the second fluid channel 7 serves as a branch air inlet and is connected to the liquid collecting chamber 51 .

[0080] In this way, by adding at least one second fluid channel 7 on the side wall 1 of the tank body and connecting the buffer chamber 41 and the liquid collecting chamber 51 through the second fluid channel 7, the air in the first fluid channel 2, the liquid collecting chamber 51 and the second fluid channel 7 can be continuously discharged to the buffer chamber 41 during the process of the heat exchange medium entering the first fluid channel 2.

[0081] At the same time, it helps to separate the air and the heat exchange medium. When the heat exchange medium initially enters the buffer chamber 41, it reduces the interference of air accumulation or poor discharge in the buffer chamber on the process of the heat exchange medium entering the buffer chamber 41, which helps the heat exchange medium to smoothly enter the buffer chamber 41.

[0082] In addition, by providing the second fluid channel 7 in an integrated manner, a compact layout can be formed, further saving space and improving the overall integration of the tank body.

[0083] It should be noted that the outlet height of the branch outlet needs to be raised, otherwise the heat exchange medium is likely to enter the second fluid channel 7, affecting the exhaust of air.

[0084] Therefore, if Figure 2 , Figure 3 , Figures 5 to 7 As shown, the electrolyte flow storage tank with cooling function also includes a branch gas outlet 8, the gas outlet channel of the branch gas outlet 8 is connected to the branch gas outlet, and the height of the gas outlet of the branch gas outlet 8 is higher than the height of the branch liquid inlet 21.

[0085] Such arrangement, through the arrangement of the branch air outlet member 8, helps to raise the air outlet height of the air discharged from the second fluid channel 7 to the buffer chamber 41, thereby preventing the heat exchange medium in the buffer chamber 41 from simultaneously entering the branch liquid inlet 21 and the branch air outlet during the process of rising liquid level. That is, the degree of interference between the process of the heat exchange medium flowing into the buffer chamber 41 and the discharged air can be reduced, so that the heat exchange medium enters the branch liquid inlet 21 during the process of rising liquid level.

[0086] At the same time, air is allowed to continuously enter the buffer chamber 41 from the second fluid channel 7, thereby improving the efficiency of the heat exchange medium entering the branch liquid inlet 21 and improving the efficiency of air discharge.

[0087] It should be noted that, in the present embodiment, the top end surface of the branch air outlet member 8 is spaced apart from the upper top plate to form a gap with a certain spacing, which helps the air flow to the ventilation main pipe 33.

[0088] It should be noted that, since air continuously enters the buffer chamber 41 , if it is not discharged in time, the pressure in the buffer chamber 41 will gradually increase, which will affect the heat exchange medium from entering the buffer chamber 41 .

[0089] Therefore, if Figure 1 , Figure 3 and Figure 5 As shown, the electrolyte flow storage tank with cooling function also includes a ventilation main pipe 33, and the ventilation main pipe 33 is installed on the side of the upper top plate in contact with the outside.

[0090] Preferably, the ventilation main pipe 33 is centrally installed in the middle portion 42 of the first top wall.

[0091] Such a configuration, by installing the additional ventilation main pipe 33 in the middle part 42 of the first top wall, helps to discharge air evenly and efficiently, reduces the impact of air on the heat exchange medium entering the first fluid channel 2, ensures that the heat exchange medium efficiently enters the first fluid channel 2, thereby ensuring that the electrolyte temperature distribution inside the liquid storage tank is more uniform, thereby improving the cooling effect.

[0092] It should be noted that, in the above embodiment, the liquid inlet main pipe 31 is installed in the radial direction of the central axis of the tank side wall 1 and is spaced from the ventilation main pipe 33 .

[0093] In this way, by arranging the liquid inlet main pipe 31 and the ventilation main pipe 33 at intervals in the radial direction of the central axis of the tank side wall 1, since the ventilation main pipe 33 is installed in the middle part 42 of the first top wall, the height of the liquid inlet port of the liquid inlet main pipe 31 entering the buffer chamber 41 will be lower than the height of the air outlet of the ventilation main pipe 33 in the buffer chamber 41, thereby reducing the interference degree of the two processes of heat exchange medium inlet and air outlet, which helps to quickly discharge the air to improve the air discharge efficiency.

[0094] It can be explained that, in the above embodiment, the extension form of the first fluid channel 2 is not specifically limited, and it can be a linear shape or a non-linear shape, such as an arc shape.

[0095] Preferably, any first fluid channel 2 extends continuously along the circumferential direction of the central axis of the tank side wall 1 and the axial direction of the central axis of the tank side wall 1 to present a spiral shape, one end of which is connected to the buffer chamber 41 and the other end is connected to the liquid collection chamber 51.

[0096] Such a configuration, by making the first fluid channel 2 present in a spiral shape, reduces the flow rate of the heat exchange medium, helps to increase the heat exchange time between the heat exchange medium and the electrolyte, and reduces the flow rate of the heat exchange medium, thereby enhancing the heat exchange efficiency, so that the heat exchange medium and the electrolyte can fully exchange heat.

[0097] At the same time, facilities with lower parameters (such as power) can be used to achieve the same cooling effect, thereby reducing energy consumption and saving energy costs.

[0098] Likewise, in the above embodiment, the extension form of the second fluid channel 7 is not specifically limited, and may be a linear shape or a non-linear shape, such as an arc shape.

[0099] Preferably, any second fluid channel 7 extends continuously along the circumferential direction of the central axis of the tank side wall 1 and the axial direction of the central axis of the tank side wall 1 to present a spiral shape, one end of which is connected to the buffer chamber 41 and the other end is connected to the liquid collection chamber 51.

[0100] Furthermore, the number of the second fluid channels 7 and the branched gas outlet components 8 are arranged in a one-to-one correspondence.

[0101] It can be explained that there is no specific limitation on the number of the liquid outlet main pipes 32. There are one or more liquid outlet main pipes 32. When there are multiple liquid outlet main pipes 32, the multiple liquid outlet main pipes 32 are arranged at intervals along the circumferential direction of the central axis of the tank side wall 1.

[0102] Such an arrangement, by providing a plurality of liquid outlet main pipes 32 and arranging the plurality of liquid outlet main pipes 32 at intervals along the circumferential direction of the central axis of the tank side wall 1, helps to discharge the heat exchange medium in time and can improve the efficiency of discharging the heat exchange medium in the liquid collecting chamber 51.

[0103] At the same time, it helps to flexibly adjust and optimize to meet actual needs when facing different working conditions or demands.

[0104] It should be noted that Figure 7 This is a perspective view of the first fluid channel and the second fluid channel on the side wall of the tank body. To facilitate viewing of the structures of each channel, the density of the first fluid channel and the density of the second fluid channel in the figure are reduced.

[0105] It should be noted that control switches, such as valves, are provided at the liquid inlet main pipe 31, the liquid outlet main pipe 32 and the ventilation main pipe 33. Before heat exchange is performed on the electrolyte inside the liquid storage tank, the valves at the liquid inlet main pipe 31, the liquid outlet main pipe 32 and the ventilation main pipe 33 are opened to allow the heat exchange medium to continuously enter the first fluid channel 2, and the air in the side wall of the tank side wall 1 is discharged through the ventilation main pipe 33.

[0106] Subsequently, the heat exchange medium circulates in the first fluid channel 2 to achieve heat exchange.

[0107] When there is no need to continue the heat exchange work on the electrolyte inside the liquid storage tank or when it needs to be stopped for other reasons, the valve of the liquid inlet main pipe 31 is closed. At this time, the heat exchange medium filled in the first fluid channel 2, the buffer chamber 41, the liquid collecting chamber 51 and the second fluid channel 7 will be continuously discharged through the liquid outlet main pipe 32 under the action of gravity, and the outside air will continuously enter the buffer chamber 41 through the ventilation main pipe 33 to maintain the gas pressure in the first fluid channel 2, the buffer chamber 41, the liquid collecting chamber 51 and the second fluid channel 7 in balance with the outside.

[0108] After all the heat exchange medium in the first fluid channel 2 , the buffer chamber 41 , the liquid collecting chamber 51 and the second fluid channel 7 is discharged, the valves at the liquid outlet main pipe 32 and the ventilation main pipe 33 are closed.

[0109] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
