Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of heat exchange, in particular to an electrolyte flow storage tank with cooling function. BACKGROUND

[0002] In the existing electrolyte cooling technology, most systems adopt the way of pipeline heat exchange to realize the cooling of electrolyte. This way mainly introduces electrolyte into an independent heat exchanger, uses cooling medium (such as water) to exchange heat with electrolyte through pipeline, so as to take away the heat in electrolyte and realize the cooling effect.

[0003] However, since the heat exchanger and the storage tank are usually designed in a split type, the complexity of the overall structure of the cooling system is caused. For example, the non-integrated design leads to low integration, occupies more space, limits the compactness and flexibility of the overall structure, and makes it difficult to adapt to space limitations in some application scenarios. SUMMARY

[0004] Therefore, the present application provides an electrolyte flow storage tank with cooling function to solve the problem of low integration caused by the split design of the heat exchanger and the storage tank.

[0005] Specifically, the present application provides an electrolyte flow storage tank with cooling function, which comprises a tank body side wall, at least one first fluid channel is opened in the tank body side wall, one end of any first fluid channel is located at one of the top and bottom of the tank body side wall, and one end of any first fluid channel is communicated with the liquid inlet main pipe as a branch liquid inlet, the other end of any first fluid channel extends towards the other of the top and bottom of the tank body side wall, and the other end of any first fluid channel is communicated with the liquid outlet main pipe as a branch liquid outlet, and the first fluid channel is used for heat exchange medium flow.

[0006] Beneficial effects: by directly opening the first fluid channel in the tank body side wall, the heat exchange medium can flow in the tank body side wall, ensuring that the electrolyte and the heat exchange medium are in full contact, 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 the excess heat, so as to keep the electrolyte in the appropriate temperature range; at the same time, by opening the first fluid channel for heat exchange medium flow in the tank body side wall, without additional heat exchanger as in the conventional scheme, space is saved, and the layout of the whole structure is more compact.

[0007] In an alternative embodiment, the electrolyte flow tank with cooling function further comprises a tank top plate set and a tank bottom plate set, the tank top plate set is located at the top of the tank side wall; the tank bottom plate set is located at the bottom of the tank side wall; wherein the tank top plate set, the tank bottom plate set and the tank side wall form a liquid storage chamber, and one of the tank top plate set and the tank bottom plate set is provided with a buffer chamber, the buffer chamber is adjacent to the liquid inlet main pipe along the axis direction of the central axis of the tank side wall and is in communication with the liquid inlet main pipe, the branch liquid inlet communicates the buffer chamber with the first fluid channel; the other of the tank top plate set and the tank bottom plate set is provided with a liquid collection chamber, the liquid collection chamber is adjacent to the liquid outlet main pipe along the axis direction of the central axis of the tank side wall and is in communication with the liquid outlet main pipe, and the branch liquid outlet communicates the first fluid channel with the liquid outlet main pipe.

[0008] Beneficial effects: by providing a buffer chamber in one of the tank top plate set and the tank bottom plate set, and making the buffer chamber adjacent to and in communication with the liquid inlet main pipe, it ensures 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 uniformly, avoiding the situation of local overheating or uneven temperature in the tank during heat exchange, thereby further improving the heat exchange efficiency; by providing a liquid collection chamber in the other of the tank top plate set and the tank bottom plate set, and making the liquid collection chamber in communication with the liquid outlet main pipe, it helps to collect the heat exchange medium flowing out of each first fluid channel, ensures that the heat is fully taken away and flows out at the liquid outlet main pipe, and realizes the smooth discharge of the heat exchange medium after being fully heat exchanged; at the same time, through the setting of the buffer chamber and the liquid collection chamber, the tank can be more compact as a whole, further improving the integration of the tank, and facilitating sampling, detection and other operations on the heat exchange medium in the buffer chamber and the liquid collection chamber.

[0009] In an alternative embodiment, the tank top plate set comprises a first top wall middle part and a first top wall peripheral part, the first top wall middle part is arched relative to the first top wall peripheral part, and the height gradually decreases in the direction from the first top wall middle part to the first top wall peripheral part; the tank top plate set further comprises a second top wall middle part and a second top wall peripheral part, the second top wall middle part is recessed relative to the second top wall peripheral part, and the height gradually increases in the direction from the second top wall middle part to the second top wall peripheral part; wherein the first top wall middle part, the first top wall peripheral part, the second top wall middle part and the second top wall peripheral part present a shuttle type structure.

[0010] Beneficial effects: By making the first top wall middle part, the first top wall peripheral part, the second top wall middle part and the second top wall peripheral part into a limited shuttle type structure, when the heat exchange medium enters the buffer chamber at the inlet liquid main, the heat exchange medium accumulates continuously, so that the liquid level of the heat exchange medium gradually rises. That is, compared with the scheme that the heat exchange medium directly enters the first fluid channel, the structure can reduce the power of the heat exchange medium, so that the heat exchange medium can enter each first fluid channel more uniformly 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 outlet liquid main, the top of the tank body side wall is divided into at least a first area and a second area, the first area is connected with the second top wall peripheral part, the height of the second area is higher than the height of the first area, and the second area is connected with the first top wall peripheral part.

[0012] Beneficial effects: By making the height of the buffer chamber higher than the height of the outlet liquid main, the buffer chamber and the inlet liquid main are arranged above the outlet liquid main, so that the heat exchange medium entering the inside of the buffer chamber at the front end enters the buffer chamber under the action of its own gravity and the heat exchange medium at the rear end. By connecting the first area with the second top wall peripheral part and connecting the second area with the first top wall peripheral part, a closed chamber is formed, so that the heat exchange medium entering the inside of the buffer chamber can gradually flow to the branch inlet liquid port as the liquid level rises, and then flow into the inside of the first fluid channel. That is, during the process of slowly rising the liquid level of the heat exchange medium entering the inside of the buffer chamber, the heat exchange medium avoids directly entering the first fluid channel without speed reduction, which helps to reduce the turbulent flow and vortex flow of the heat exchange medium in the buffer chamber, so that the heat exchange medium can enter the inside of each first fluid channel more uniformly and smoothly, thereby improving the heat exchange efficiency.

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

[0014] Beneficial effects: By adding at least one second fluid passage to the side wall of the tank body, and making the second fluid passage communicate the buffer chamber and the liquid collecting chamber, the air in the first fluid passage, the liquid collecting chamber and the second fluid passage can be continuously discharged to the buffer chamber during the process of the heat exchange medium entering the first fluid passage. At the same time, it helps to separate the air and the heat exchange medium, 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 during the process of the heat exchange medium initially entering the buffer chamber, and helps the heat exchange medium to smoothly enter the buffer chamber. In addition, by integrating the second fluid passage, a compact layout can be formed, further saving space and improving the integration of the tank body as a whole.

[0015] In an alternative embodiment, the electrolyte flow tank with cooling function further comprises a branch air outlet member, an air outlet passage of the branch air outlet member communicates with the branch air outlet, and the height of the air outlet of the branch air outlet member is higher than the height of the branch liquid inlet.

[0016] Beneficial effects: By the arrangement of the branch air outlet member, the air outlet height of the second fluid passage to the buffer chamber is raised, avoiding the heat exchange medium in the buffer chamber from entering the branch liquid inlet and the branch air outlet at the same time during the process of the liquid level rising, that is, the interference degree between the process of the heat exchange medium flowing into the buffer chamber and the discharged air can be reduced, so that the efficiency of the heat exchange medium entering the branch liquid inlet and the efficiency of air discharge are improved.

[0017] In an alternative embodiment, the electrolyte flow tank with cooling function further comprises an air exchange main pipe, which is centrally installed in the middle part of the first top wall.

[0018] Beneficial effects: By installing the added air exchange main pipe in the middle part of the first top wall, the air can be uniformly and efficiently discharged, the influence of the air on the heat exchange medium entering the first fluid passage is reduced, the heat exchange medium can efficiently enter the first fluid passage, so that the temperature distribution of the electrolyte in the tank is more uniform, and the cooling effect is improved.

[0019] In an alternative embodiment, the liquid inlet main pipe is arranged in a radial direction of the central axis of the tank body and is spaced apart from the air exchange main pipe.

[0020] Beneficial effect: By arranging the liquid inlet main pipe and the air exchange main pipe in a radial direction of the central axis of the tank side wall, and by installing the air exchange main pipe in the middle of the first top wall, the height of the liquid inlet port of the liquid inlet main pipe into the buffer chamber is lower than the height of the air outlet port of the air exchange main pipe into the buffer chamber, the interference degree of the processes of the heat exchange medium liquid inlet and the air outlet is reduced, and the air is quickly discharged to improve the air discharge efficiency.

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

[0022] Beneficial effect: By presenting the first fluid channel in a spiral shape, the flow rate of the heat exchange medium is reduced, the heat exchange time of the heat exchange medium and the electrolyte is increased, the heat exchange efficiency is enhanced, the heat exchange medium and the electrolyte are fully heat exchanged, and the same cooling effect can be achieved by using a facility with lower parameters (such as power), thereby reducing energy consumption and saving energy costs.

[0023] In an alternative embodiment, the liquid outlet main pipe is provided with a plurality of liquid outlet main pipes, and the plurality of liquid outlet main pipes are arranged in a circumferential direction of the central axis of the tank side wall.

[0042] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme of the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are some of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0043] In the description of the present application, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application. In addition, the terms "first", "second", "third" are only for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0044] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connecting" should be understood in a broad sense, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0045] In addition, the technical features involved in the different embodiments of the application described below can be combined with each other as long as there is no conflict between them.

[0046] In conventional technology, the heat exchanger and the liquid storage tank are usually designed in a split type. The electrolyte such as vanadium liquid is introduced into a separate heat exchanger, and the cooling medium (such as water or air) is used to exchange heat with the electrolyte through pipelines, so as to take away the heat in the electrolyte. With such an arrangement, the electrolyte needs to circulate between the liquid storage tank and the heat exchanger. However, this will increase the length of the connecting members and the pipelines, not only increasing the manufacturing cost of the system, but also increasing the potential risk of leakage. At the same time, the non-integrated design leads to low integration and occupies more space, limiting the compactness and flexibility of the overall structure, making it difficult to adapt to space limitations in some application scenarios.

[0047] Therefore, the present application directly adds a channel for the flow of heat exchange medium and a channel for the discharge of gas at the side wall of the liquid storage tank to improve the overall integration and reduce the length of the connecting members and the pipelines, thereby improving the phenomenon of electrolyte leakage.

[0048] The embodiments of the present application will be described below in conjunction with Figures 1 to 7 .

[0049] As shown in Figure 1 , the present application provides an electrolyte flow liquid storage tank with cooling function, which comprises a tank body side wall 1. A first fluid channel 2 extending between the top of the tank body and the bottom of the tank body is formed in the tank body side wall 1.

[0050] It can be explained that the number of the first fluid passages 2 is not specifically limited. There can be one, two or more.

[0051] At this time, one end of any first fluid passage 2 is located at one of the top and bottom of the tank side wall 1 and communicates with the liquid inlet manifold 31 as a branch liquid inlet port 21, and the other end of any first fluid passage 2 extends towards the other of the top and bottom of the tank side wall 1 and communicates with the liquid outlet manifold 32 as a branch liquid outlet port 22, and the first fluid passage 2 is used for the flow of the heat exchange medium.

[0052] Therefore, by directly providing the first fluid passage 2 in the tank side wall 1, the heat exchange medium can circulate in the tank side wall 1, 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 rises, the heat exchange medium can effectively absorb and take away the excess heat, thereby keeping the electrolyte within the appropriate temperature range.

[0053] At the same time, by providing the first fluid passage 2 for the flow of the heat exchange medium in the tank side wall 1, there is no need to additionally provide a heat exchanger as in the conventional scheme, thereby saving space, making the overall structure more compact, avoiding the electrolyte from being led out of the tank, reducing the number of connecting components, reducing the complexity and potential leakage risk of the overall structure, and simplifying the installation and maintenance processes, thereby improving the reliability and durability of the overall structure.

[0054] In addition, since the first fluid passage 2 extends between the top and 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 enclosed by the tank side wall 1 for storing the electrolyte is columnar or conical.

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

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

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

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

[0060] In this way, by providing the buffer chamber 41 in one of the tank top plate group 4 and the tank bottom plate group 5, and arranging the buffer chamber 41 adjacent to the liquid inlet main pipe 31 and in communication 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 uniformly, avoiding the situation of local overheating or uneven temperature of the tank during heat exchange, thereby further improving the heat exchange efficiency.

[0061] And by providing the liquid collecting chamber 51 in the other one of the tank top plate group 4 and the tank bottom plate group 5, and arranging the liquid collecting chamber 51 in communication with the liquid outlet main pipe 32, it is helpful to collect the heat exchange medium flowing out of each first fluid channel 2, ensuring that the heat is fully taken away and flows out at the liquid outlet main pipe 32, realizing the smooth discharge of the heat exchange medium after being fully heat exchanged.

[0062] At the same time, through the arrangement of the buffer chamber 41 and the liquid collecting chamber 51, the tank can be made more compact, further improving the integration of the tank, and facilitating sampling, detection and other operations of the heat exchange medium at the buffer chamber 41 and the liquid collecting chamber 51.

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

[0064] It can be explained that in the present application, the shape of the liquid collecting chamber 51 is not limited. It can be any one of circular ring, circular cylinder or spiral.

[0065] It can be explained that in the embodiment, the connection between the tank top plate group 4, the tank side wall 1 and the tank bottom plate group 5 adopts a solidification mode of fusion or an integral molding mode.

[0066] It can be noted that, in the above embodiment, the tank top plate assembly 4 includes two top plates, which are defined as the upper top plate and the 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 direction of the central axis of the tank side wall 1).

[0067] The upper and lower top plates include at least one bent top plate.

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

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

[0070] Of course, it can also be configured such that: the tank top plate assembly 4 includes a first top wall middle portion 42 and a first top wall peripheral portion 43, the first top wall middle portion 42 is arched relative to the first top wall peripheral portion 43, and its height gradually decreases in the direction extending from the first top wall middle portion 42 to the first top wall peripheral portion 43; the tank top plate assembly 4 also includes a second top wall middle portion 44 and a second top wall peripheral portion 45, the second top wall middle portion 44 is recessed relative to the second top wall peripheral portion 45, and its height gradually increases in the direction extending from the second top wall middle portion 44 to the second top wall peripheral portion 45. This allows the first top wall middle portion 42, the first top wall peripheral portion 43, the second top wall middle portion 44, and the second top wall peripheral portion 45 to have a spindle-shaped structure.

[0071] This configuration, by making the middle portion 42, the peripheral portion 43, the middle portion 44, and the peripheral portion 45 of the first top wall form a limiting shuttle-shaped structure, allows the heat exchange medium to continuously accumulate as it enters the buffer chamber 41 through the inlet manifold 31, causing the liquid level of the heat exchange medium to gradually rise. That is, compared to the scheme where the heat exchange medium directly enters the first fluid channel 2, this structure reduces the driving force of the heat exchange medium, allowing it to enter each of the first fluid channels 2 more uniformly and smoothly, thereby further improving heat exchange efficiency.

[0072] In addition, the shuttle-shaped structure helps guide airflow to the ventilation manifold 33, thereby improving air emission efficiency.

[0073] It should be noted that the specific location of the buffer chamber 41 is not limited. It can be located at the top or bottom of the tank.

[0074] Preferably, such as Figure 1 , Figure 3 , Figure 5 and Figure 6As shown, the buffer chamber 41 is arranged at 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.

[0075] Further, in order to increase the volume of the buffer chamber, the top of the tank body side wall 1 is divided into at least a first region 11 and a second region 12. The first region 11 is connected, such as welded or integrally formed, with the first top wall peripheral part 45, and the height of the second region 12 is higher than the height of the first region 11. The second region 12 is connected, such as welded or integrally formed, with the second top wall peripheral part 43.

[0076] In this way, by arranging the buffer chamber 41 and the liquid inlet main pipe 31 above the liquid outlet main pipe 32, and by connecting the first region 11 with the first top wall peripheral part 45 and connecting the second region 12 with the second top wall peripheral part 43 to form a closed chamber, the heat exchange medium entering the inside of the buffer chamber 41 can gradually flow to the branch liquid inlet 21 and then flow into the first fluid passage 2 as the liquid level rises.

[0077] That is, by avoiding the heat exchange medium from directly entering the first fluid passage 2 without being slowed down during the process of the heat exchange medium slowly rising in the buffer chamber 41, it helps to reduce the turbulence and vortex of the heat exchange medium in the buffer chamber 41, so that the heat exchange medium can more evenly and smoothly enter the inside of each first fluid passage 2, thereby improving the heat exchange efficiency.

[0078] In this application, an independent channel for discharging air is additionally provided.

[0079] Specifically, as shown, Figures 1 to 7 The tank body side wall 1 is also provided with at least one second fluid passage 7. One end of the second fluid passage 7 serves as a branch air outlet and is in communication with the buffer chamber 41, and the other end of the second fluid passage 7 serves as a branch air inlet and is in communication with the liquid collecting chamber 51.

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

[0081] At the same time, it is helpful to separate the air and the heat exchange medium, and to reduce the interference of the air accumulation or poor discharge in the buffer chamber on the process of the heat exchange medium entering the buffer chamber 41 during the preliminary entry of the heat exchange medium into the buffer chamber 41, which helps the smooth entry of the heat exchange medium into the buffer chamber 41.

[0082] In addition, by integrating the second fluid channel 7, a compact layout can be formed, further saving space and improving the integration of the entire tank.

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

[0084] Therefore, as shown in Figure 2 , Figure 3 , Figures 5 to 7 The electrolyte flow tank with cooling function also includes a branch air outlet member 8, the air outlet channel of the branch air outlet member 8 is in communication with the branch air outlet, and the height of the air outlet of the branch air outlet member 8 is higher than the height of the branch liquid inlet 21.

[0085] In this way, by providing the branch air outlet member 8, the height of the air outlet of the second fluid channel 7 to the buffer chamber 41 is raised, avoiding the heat exchange medium in the buffer chamber 41 from entering the branch liquid inlet 21 and the branch air outlet at the same time during the process of the liquid level rising, that is, the interference degree between the process of the heat exchange medium flowing into the inside of the buffer chamber 41 and the air exhaust can be reduced, so that the heat exchange medium enters the branch liquid inlet 21.

[0086] At the same time, the 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 the efficiency of the air exhaust.

[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 distance, which helps the air to flow to the air exchange manifold 33.

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

[0089] Therefore, as shown in Figure 1 , Figure 3 and Figure 5 The electrolyte flow tank with cooling function also includes an air exchange manifold 33, which is installed on the side of the upper top plate in contact with the outside.

[0090] Preferably, the air exchange main pipe 33 is centrally installed at the middle part 42 of the first top wall.

[0091] In this way, by installing the air exchange main pipe 33 at the middle part 42 of the first top wall, the air can be uniformly and efficiently discharged, the influence of the air on the entry of the heat exchange medium into the first fluid passage 2 is reduced, the efficient entry of the heat exchange medium into the first fluid passage 2 is ensured, and thus the temperature distribution of the electrolyte inside the liquid storage tank is more uniform, and the cooling effect is improved.

[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 apart from the air exchange main pipe 33.

[0093] In this way, by installing the liquid inlet main pipe 31 and the air exchange main pipe 33 in the radial direction of the central axis of the tank side wall 1 and spacing them apart, since the air exchange main pipe 33 is installed at the middle part 42 of the first top wall, the height of the liquid inlet of the liquid inlet main pipe 31 into the buffer chamber 41 will be lower than the height of the air in the buffer chamber 41 entering the air outlet of the air exchange main pipe 33, the interference degree of the heat exchange medium liquid inlet and the air outlet is reduced, and the air can be quickly discharged to improve the air discharge efficiency.

[0094] It should be noted that in the above embodiment, the extension form of the first fluid passage 2 is not specifically limited, and can be linear or non-linear, such as arc-shaped.

[0095] Preferably, any first fluid passage 2 continuously extends 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 communicates with the buffer chamber 41 and the other end of which communicates with the liquid collecting chamber 51.

[0096] In this way, by presenting the first fluid passage 2 in a spiral shape, the flow rate of the heat exchange medium is reduced, the heat exchange time of the heat exchange medium and the electrolyte is increased, and the flow rate of the heat exchange medium is reduced, thereby enhancing the heat exchange efficiency and enabling the heat exchange medium and the electrolyte to fully exchange heat.

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

[0098] Similarly, in the above embodiment, the extension form of the second fluid passage 7 is not specifically limited, and can be linear or non-linear, such as arc-shaped.

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

[0100] Further, the number of second fluid channels 7 corresponds to the number of branch gas outlets 8.

[0101] It should be noted that the number of liquid outlet pipes 32 is not specifically limited. The liquid outlet pipe 32 is provided with one or more. When multiple liquid outlet pipes 32 are provided, the multiple liquid outlet pipes 32 are arranged at intervals along the circumferential direction of the central axis of the tank sidewall 1.

[0102] In this way, by providing multiple liquid outlet pipes 32 and arranging the multiple liquid outlet pipes 32 at intervals along the circumferential direction of the central axis of the tank sidewall 1, the heat exchange medium can be discharged in time, and the efficiency of discharging the heat exchange medium into the liquid collection chamber 51 can be improved.

[0103] At the same time, it is helpful to flexibly adjust and optimize in the face of different working conditions or needs to meet actual needs.

[0104] It should be noted that, Figure 7 For the perspective view of the first fluid channel and the second fluid channel of the tank sidewall, in order to facilitate the viewing of the structure of each channel, the density of the first fluid channel and the density of the second fluid channel in the drawing are reduced.

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

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

[0107] When it is not necessary to continue the heat exchange work on the electrolyte inside the liquid storage tank or other reasons require stopping, the valve of the liquid inlet pipe 31 is in a closed state. At this time, the heat exchange medium filled in the first fluid channel 2, the buffer chamber 41, the liquid collection chamber 51, and the second fluid channel 7 will continuously be discharged through the liquid outlet pipe 32 under the action of gravity, and the air outside continuously enters the buffer chamber 41 through the gas exchange pipe 33 to maintain the gas pressure in the first fluid channel 2, the buffer chamber 41, the liquid collection chamber 51, and the second fluid channel 7 balanced with the outside.

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

[0109] Obviously, the above embodiments are merely exemplary and not limiting. Based on the above description, one of ordinary skill in the art can make other different forms of changes or modifications. Here, it is not necessary and impossible to exhaust all the embodiments. The obvious changes or modifications derived therefrom are still within the protection scope of the present application.
