Technical Field
[0001] This application relates to the technical field of batteries, and particularly to a water cooling system, a battery, and an electrical equipment. Background Art
[0002] A battery is a device that can convert chemical energy into electrical energy and can provide electrical energy for numerous electrical appliances, enabling the electrical appliances to be in a working state. Existing batteries are widely used in power fields such as automobiles, construction machinery equipment, and ships, and can also be used for household energy storage, industrial and commercial energy storage, communication base stations, etc.
[0003] A battery generally includes a water cooling system to improve the heat dissipation efficiency of the battery through the water cooling system and ensure the reliability of battery use.
[0004] Based on the structure of the existing water cooling system, the overall structure of the battery will be relatively large, resulting in a low energy density of the battery. Summary of the Utility Model
[0005] This application provides a water cooling system, a battery, and an electrical equipment to reduce the volume of the battery and improve the energy density of the battery.
[0006] In a first aspect, an example of this application provides a water cooling system, which includes a corrugated tube assembly, a first manifold, and a second manifold. The corrugated tube assembly includes a water inlet and a water outlet, and the corrugated tube assembly includes at least one corrugated tube with at least one water cooling pipeline provided inside. The first manifold includes a first connection surface provided with a first connection hole, the first connection hole communicates with the water inlet, and at least a part of the first manifold is arranged between the corrugated tube assembly and the bottom wall of the battery housing. The second manifold includes a second connection surface provided with a second connection hole, the second connection hole communicates with the water outlet, and at least a part of the second manifold is arranged between the corrugated tube assembly and the bottom wall.
[0007] Wherein, the corrugated tube includes a first bending section and a second bending section. The first bending section bends towards the first connection surface, the water inlet is arranged on one side of the first bending section facing the first connection surface, the second bending section bends towards the second connection surface, and the water outlet is arranged on one side of the second bending section facing the second connection surface.
[0008] According to the water cooling system provided by the example of this application, the cooperation of the first manifold, the corrugated tube assembly, and the second manifold can provide a flow channel for the condensate, enabling the water cooling system to improve the cooling efficiency of the battery.
[0009] Since at least part of the first current collector pipe is arranged between the harmonica pipe assembly and the bottom wall of the battery housing, the distance between the first connection hole and the top wall of the battery housing can be made greater than the distance between the harmonica pipe assembly and the top wall of the battery housing. Furthermore, the first current collector pipe occupies less or even no volume between the harmonica pipe assembly and the top wall of the battery housing. And since at least part of the second current collector pipe is arranged between the harmonica pipe assembly and the bottom wall of the battery housing, the distance between the second connection hole and the top wall of the battery housing can be made greater than the distance between the harmonica pipe assembly and the top wall of the battery housing. Furthermore, the second current collector pipe occupies less or even no volume between the harmonica pipe assembly and the top wall of the battery housing. As a result, the volume of the battery housing is reduced, and the volumetric energy density of the battery is increased.
[0010] In some possible implementation manners, the first bent section is substantially perpendicular to the first connection surface. And / or, the second bent section is substantially perpendicular to the second connection surface.
[0011] By setting the first bent section to be substantially perpendicular to the first connection surface, it is convenient for the operator to perform welding between the first bent section and the first connection surface, and the welding yield between the first bent section and the first connection surface is improved. By setting the second bent section to be substantially perpendicular to the second connection surface, it is convenient for the operator to perform welding between the second bent section and the second connection surface, and the welding yield between the second bent section and the second connection surface is improved.
[0012] In some possible implementation manners, the harmonica pipe further includes a body pipe. A first included angle is formed between the body pipe and the first bent section, and the first included angle is substantially equal to 120 degrees. And / or, a second included angle is formed between the body pipe and the second bent section, and the second included angle is substantially equal to 120 degrees.
[0013] The body pipe of the harmonica pipe can be substantially parallel to the bottom wall of the battery housing. Since the side of the first current collector pipe facing the bottom wall of the battery housing is substantially parallel to the battery housing, and the angle between the body pipe of the harmonica pipe and the first bent section is substantially equal to 120 degrees, and the first bent section is substantially perpendicular to the first connection surface, therefore, the angle between the first connection surface and the bottom wall of the battery housing is substantially equal to 60 degrees. The first current collector pipe can be in the shape of a regular triangular prism, a rhombic prism or other prismatic shapes, which is convenient for obtaining materials and processing of the first current collector pipe, and can reduce the manufacturing cost of the water cooling system. The specific shape of the first current collector pipe is not limited in the examples of this application.
[0014] In some possible implementation manners, an arc is formed at the connection between the first bent section and the body pipe. And / or, an arc is formed at the connection between the second bent section and the body pipe.
[0015] The connection between the first bent section and the main body pipe forms an arc, which can reduce the loss of condensate during the process of reaching the first bent section via the first manifold, and improve the heat dissipation efficiency of the water cooling system. The connection between the second bent section and the main body pipe forms an arc, which can reduce the loss of condensate during the process of reaching the second bent section via the second manifold, and improve the heat dissipation efficiency of the water cooling system.
[0016] In some possible implementation manners, the first manifold and the second manifold are located on the same side of the mouthpiece pipe assembly. The mouthpiece pipe assembly further includes a first mouthpiece pipe group, a second mouthpiece pipe group, and a connecting manifold. The first mouthpiece pipe group includes a water inlet and a sub-outlet, the second mouthpiece pipe group includes a sub-inlet and a water outlet, and the connecting manifold is disposed on a side of the first mouthpiece pipe group away from the first manifold.
[0017] The first mouthpiece pipe group is communicated with the first manifold through the water inlet, the first mouthpiece pipe group is communicated with the connecting manifold at a first position of the connecting manifold through the sub-outlet, the second mouthpiece pipe group is communicated with the manifold at a second position of the connecting manifold through the sub-inlet, the second mouthpiece pipe group is communicated with the second manifold through the water outlet, and the first position and the second position are spaced apart.
[0018] Based on the water cooling system provided in the above example, the condensate can sequentially enter the first mouthpiece pipe group from the water inlet via the first manifold, enter the connecting manifold from the sub-outlet of the first mouthpiece pipe group, enter the second mouthpiece pipe group from the sub-inlet via the connecting manifold, enter the second manifold from the water outlet of the second mouthpiece pipe group, and finally flow out of the water cooling system, improving the utilization efficiency of the condensate.
[0019] In some possible implementation manners, the water cooling system further includes a partition assembly, and the partition assembly is disposed between the first manifold and the second manifold. One end of the partition assembly is connected to the first manifold, the other end of the partition assembly is connected to the second manifold, and the partition assembly partitions the first manifold and the second manifold.
[0020] By providing the partition assembly, one manifold can be partitioned into a first manifold and a second manifold, which can improve the assembly efficiency of the water cooling system and reduce the manufacturing cost of the water cooling system.
[0021] In some possible implementation manners, the partition assembly includes a first partition member and a second partition member that are spaced apart, and the first partition member is disposed closer to the water inlet than the second partition member.
[0022] By providing the first baffle and the second baffle, and arranging the first baffle closer to the water inlet relative to the second baffle, the distance between the first baffle and the water inlet can be reduced, and the possibility of condensate accumulating between the first baffle and the water inlet and being unable to flow can be decreased. By arranging the second baffle closer to the water outlet relative to the first baffle, the distance between the second baffle and the water outlet can be reduced, and the possibility of condensate accumulating between the second baffle and the water outlet and being unable to flow can be decreased.
[0023] In some possible implementation manners, the number of harmonica tubes included in the first harmonica tube group is a first value, the number of harmonica tubes included in the second harmonica tube group is a second value, the ratio of the first value to the second value is 5 / 7, and the baffle assembly is arranged between the first harmonica tube group and the second harmonica tube group.
[0024] By setting the ratio of the first value to the second value to be 5 / 7, and arranging the baffle assembly between the first harmonica tube group and the second harmonica tube group, the flow resistance of the condensate in the water cooling system can be made smaller, thereby improving the heat dissipation efficiency of the water cooling system.

The housing is provided with a receiving cavity, the battery cell is arranged in the receiving cavity, and the water cooling system is arranged on one side of the battery cell and closes the opening of the receiving cavity.

[0044] A battery is a device that can provide electrical energy for an electrical appliance, enabling the electrical appliance to be in a working state. A battery generally includes a battery cell, a water cooling system, a housing, and other structures. The housing can provide a receiving space for the battery cell, and the water cooling system can improve the heat dissipation efficiency of the battery, ensuring the reliability and safety of the battery during use.
[0045] Based on the structure of the existing water cooling system, the water cooling system includes a manifold and a corrugated tube. The corrugated tube is disposed substantially parallel to the top wall of the housing. Along the direction from the top wall to the bottom wall of the housing, a part of the manifold protrudes above the corrugated tube. In order to ensure that the housing can provide sufficient installation space for the water cooling system, the housing can only be set to be relatively large, resulting in a relatively large volume of the battery, and thus a relatively low volumetric energy density of the battery.
[0046] Based on the above, the present application provides an example of a water cooling system, a battery, and an electrical device.
[0047] In order to enable those skilled in the art to better understand the solution of the present application, the water cooling system, the battery, and the electrical device provided by the examples of the present application will be clearly and completely described below with reference to the drawings.
[0048] Exemplarily, the present application provides an example of an electrical device, and the electrical device includes a battery.
[0049] The electrical device uses a battery as its power source. The electrical device can be, but is not limited to, a mobile phone, a tablet computer, a laptop computer, an electric toy, an electric tool, an electric vehicle, an electric car, a ship, a spacecraft, etc.
[0050] Next, a brief introduction to the battery mentioned in the above example will be given.
[0051] Exemplarily, the battery may include a housing, a water cooling system, and one or more battery cells. The housing is provided with a receiving cavity, the battery cells are arranged in the receiving cavity, and the water cooling system is installed on the housing and located on one side of the battery cells. By setting up the water cooling system, the heat dissipation efficiency of the battery can be improved, ensuring the safety of battery use.
[0052] The housing can adopt various structures. For example, the housing can be in the shape of a cylinder, a cuboid or other cube. In this application example, only cylindrical batteries are described as examples.
[0053] In the battery, there can be multiple battery cells. The multiple battery cells can be connected in series, in parallel, or in a combination of series and parallel. A combination of series and parallel means that there are both series and parallel connections among the multiple battery cells. The multiple battery cells can be directly connected in series, in parallel, or in a combination of series and parallel together, and then the whole formed by the multiple battery cells is accommodated in the housing. Of course, the battery can also be that multiple battery cells are first connected in series, in parallel, or in a combination of series and parallel to form a battery module, and then multiple battery modules are connected in series, in parallel, or in a combination of series and parallel to form a whole and are accommodated in the housing. The battery can also include other structures. For example, the battery can also include a busbar component for realizing the electrical connection among the multiple battery cells. Among them, each battery cell can be a secondary battery or a primary battery. It can also be a lithium-sulfur battery, a sodium-ion battery or a magnesium-ion battery, but is not limited thereto.
[0054] Next, the specific structure of the water cooling system will be described in detail.
[0055] Exemplarily, an example of the present application provides a water cooling system. Figure 1 It is a schematic structural diagram of a first perspective of a water cooling system provided by an example of the present application. Figure 2 It is a schematic structural diagram of a second perspective of a water cooling system provided by an example of the present application. Please refer to Figure 1 With Figure 2, the water cooling system 100 may include a corrugated tube assembly 130, a first header 110, and a second header 120. The corrugated tube assembly 130 may include a water inlet and a water outlet. The corrugated tube assembly 130 may include at least one corrugated tube 131, and at least one water cooling pipe is provided inside the corrugated tube 131. The first header 110 includes a first connection surface provided with a first connection hole, and the first connection hole is communicated with the water inlet. At least a part of the first header 110 is disposed between the corrugated tube assembly 130 and the bottom wall of the battery housing. The second header 120 includes a second connection surface provided with a second connection hole, and the second connection hole is communicated with the water outlet. At least a part of the second header 120 is disposed between the corrugated tube assembly 130 and the bottom wall.
[0056] Wherein, the corrugated tube 131 includes a first bent section 1311 and a second bent section 1312. The first bent section 1311 is bent toward the first connection surface, and the water inlet is disposed on one side of the first bent section 1311 facing the first connection surface. The second bent section 1312 is bent toward the second connection surface, and the water outlet is disposed on one side of the second bent section 1312 facing the second connection surface.
[0057] The water inlet of the corrugated tube assembly 130 may be composed of the water inlets of a plurality of corrugated tubes 131, and the water outlet of the corrugated tube assembly 130 may be composed of the water outlets of a plurality of corrugated tubes 131.
[0058] The corrugated tube assembly 130 may have various implementation manners.
[0059] Exemplarily, please refer to Figure 1 , the corrugated tube assembly 130 may include a plurality of corrugated tubes 131, and the plurality of corrugated tubes 131 may be arranged substantially parallel to each other. The corrugated tube 131 includes a first bent section 1311 and a second bent section 1312. At this time, the water outlet and the water inlet of the corrugated tube assembly 130 may be located at opposite ends of the corrugated tube assembly 130, that is, the first header 110 and the second header 120 are located at both ends of the corrugated tube assembly 130. Since the first bent section 1311 is bent toward the first connection surface and the water inlet is provided at one end of the first bent section 1311 close to the first connection surface, and the second bent section 1312 is bent toward the second connection surface and the water outlet is provided at one end of the second bent section 1312 close to the second connection surface, therefore, the first bent section 1311 and the second bent section 1312 may be located at both ends of the same corrugated tube 131, that is, located at both ends of the corrugated tube assembly 130. The flow path of the condensate in the corrugated tube assembly 130 may be in an "L" shape.
[0060] Exemplarily, Figure 3 For another structural schematic diagram of the first perspective of the water cooling system provided by the example of the present application, please refer to Figure 3, the harmonica tube assembly 130 may also include a connection structure and multiple harmonica tubes 131, and the connection structure connects the multiple harmonica tubes 131. At this time, the water inlet and the water outlet of the harmonica tube assembly 130 may be located on the same side of the harmonica tube assembly 130, that is, the first manifold 110 and the second manifold 120 may be located at the same end of the harmonica tube assembly 130. Since the first bent section 1311 is bent toward the first connection surface and a water inlet is provided at one end of the first bent section 1311 close to the first connection surface, and the second bent section 1312 is bent toward the second connection surface and a water outlet is provided at one end of the second bent section 1312 close to the second connection surface, therefore, the first bent section 1311 and the second bent section 1312 may be located on the same side of different harmonica tubes 131, that is, at the same end of the harmonica tube assembly 130. The flow path of the condensate in the harmonica tube assembly 130 may be in a "U" shape.
[0061] Whether the harmonica tube assembly 130 only includes multiple harmonica tubes 131 or the harmonica tube assembly 130 includes multiple harmonica tubes and a connection structure, at least one water cooling pipe may be provided in each harmonica tube 131.
[0062] For the specific structure of the harmonica tube assembly 130, please refer to the relevant description below and will not be elaborated here, only for example.
[0063] The structure of the first manifold 110 is similar to the structure of the second manifold 120, the structure of the first bent portion is similar to the structure of the second bent portion, and the functions are similar. Next, only the first manifold 110 and the first bent portion will be described as examples.
[0064] The first manifold 110 may include a first connection surface provided with a first connection hole. There may be multiple first connection holes. At this time, the number of the first connection holes may be equal to and in one-to-one correspondence with the number of the harmonica tubes 131 having water inlets. The first connection hole may also be provided with only one, and multiple harmonica tubes 131 may be connected into an integral structure through a connecting member and connected to the first connection hole. The number of the first connection holes may also be less than the number of the harmonica tubes 131. Two adjacent, three adjacent or multiple adjacent harmonica tubes 131 may be connected into an integral structure through a connecting member and connected to the first connection hole. The present application example does not specifically limit the setting manner of the first connection hole and the harmonica tubes 131.
[0065] At least a part of the first manifold 110 is provided between the harmonica tube assembly 130 and the bottom wall of the battery housing. It can be understood that the distance between the first connection hole and the bottom wall of the battery housing is less than the distance between the harmonica tube assembly 130 and the bottom wall of the battery housing. Based on this, it can be ensured that the distance between the first connection hole and the top wall of the battery housing is greater than the distance between the harmonica tube assembly 130 and the top wall of the battery housing.
[0066] The harmonica tube 131 may include a first bent section 1311 and a second bent section 1312.
[0067] The first bent section 1311 can be bent towards the first connection surface, and a water inlet is provided at one end of the first bent section 1311 close to the first connection surface. The first bent section 1311 can be connected to the first connection surface, so that the water inlet provided on the first bent section 1311 communicates with the first connection hole provided on the first connection surface, thereby enabling the condensate to flow to the mouthpiece tube assembly 130 via the first manifold 110, which is convenient for improving the cooling efficiency of the water cooling system 100 for the battery.
[0068] The second bent section 1312 can be bent towards the second connection surface, and a water outlet is provided at one end of the second bent section 1312 close to the second connection surface. The second bent section 1312 can be connected to the second connection surface, so that the water outlet provided on the second bent section 1312 communicates with the second connection hole provided on the second connection surface, thereby enabling the condensate to flow to the mouthpiece tube assembly 130 via the second manifold 120, which is convenient for improving the cooling efficiency of the water cooling system 100 for the battery.
[0069] A non-zero angle can exist between the first bent section 1311 and the first connection surface, and this angle can be any one of an acute angle, a right angle, or an obtuse angle. A non-zero angle can also exist between the second bent section 1312 and the second connection surface, and this angle can also be any one of an acute angle, a right angle, or an obtuse angle.
[0070] The shapes of the first manifold 110 and the second manifold 120 can be the same. Hereinafter, only the first manifold 110 will be taken as an example to describe the shapes of the first manifold 110 and the second manifold 120. Exemplarily, the first manifold 110 can be in the shape of a triangular prism, a quadrangular prism, or other shapes. One side of the first manifold 110 facing the bottom wall of the battery housing can be substantially parallel to the bottom wall of the battery housing.
[0071] Based on the above, according to the water cooling system 100 provided by the examples of the present application, the cooperation of the first manifold 110, the mouthpiece tube assembly 130, and the second manifold 120 can provide a flow passage for the condensate, so that the water cooling system 100 can improve the cooling efficiency of the battery.
[0072] Since at least part of the first current collector tube 110 is disposed between the harmonica tube assembly 130 and the bottom wall of the battery housing, the distance between the first connection hole and the top wall of the battery housing can be made greater than the distance between the harmonica tube assembly 130 and the top wall of the battery housing. As a result, the first current collector tube 110 occupies less or even no volume between the harmonica tube assembly 130 and the top wall of the battery housing. And since at least part of the second current collector tube 120 is disposed between the harmonica tube assembly 130 and the bottom wall of the battery housing, the distance between the second connection hole and the top wall of the battery housing can be made greater than the distance between the harmonica tube assembly 130 and the top wall of the battery housing. Thus, the second current collector tube 120 occupies less or even no volume between the harmonica tube assembly 130 and the top wall of the battery housing, thereby reducing the volume of the battery housing and increasing the volumetric energy density of the battery.
[0073] Based on the water cooling system 100 provided in the above example, the first bending section 1311 is substantially perpendicular to the first connection surface. And / or, the second bending section 1312 is substantially perpendicular to the second connection surface.
[0074] The first bending section 1311 being substantially perpendicular to the first connection surface may mean that the angle between the first bending section 1311 and the first connection surface is greater than or equal to 85° and less than or equal to 95°.
[0075] The second bending section 1312 being substantially perpendicular to the second connection surface may mean that the angle between the second bending section 1312 and the second connection surface is greater than or equal to 85° and less than or equal to 95°.
[0076] In the water cooling system 100 provided in the example of the present application, it may be that only the first bending section 1311 is substantially perpendicular to the first connection surface, or only the second bending section 1312 is substantially perpendicular to the second connection surface, or both the first bending section 1311 is substantially perpendicular to the first connection surface and the second bending section 1312 is substantially perpendicular to the second connection surface. The example of the present application does not make specific limitations in this regard.
[0077] By setting the first bending section 1311 to be substantially perpendicular to the first connection surface, it is convenient for the operator to perform welding between the first bending section 1311 and the first connection surface, improving the welding yield between the first bending section 1311 and the first connection surface. By setting the second bending section 1312 to be substantially perpendicular to the second connection surface, it is convenient for the operator to perform welding between the second bending section 1312 and the second connection surface, improving the welding yield between the second bending section 1312 and the second connection surface.
[0078] Based on the water cooling system 100 provided in the above example, please refer to Figure 2, the harmonica tube 131 may further include a main body tube 1313. A first included angle is formed between the main body tube 1313 and the first bent section 1311, and the first included angle may be substantially equal to 120 degrees. And / or, a second included angle is formed between the main body tube 1313 and the second bent section 1312, and the second included angle may be substantially equal to 120 degrees.
[0079] The first included angle being substantially equal to 120 degrees means that the first included angle is greater than or equal to 115 degrees and less than or equal to 125 degrees.
[0080] The second included angle being substantially equal to 120 degrees means that the second included angle is greater than or equal to 115 degrees and less than or equal to 125 degrees.
[0081] A fold angle may be formed at the connection between the main body tube 1313 and the first bent section 1311, and the connection between the main body tube 1313 and the first bent section 1311 may also be transitioned by an arc. A fold angle may be formed at the connection between the main body tube 1313 and the second bent section 1312, and the connection between the main body tube 1313 and the second bent section 1312 may also be transitioned by an arc. The present application example does not limit this.
[0082] The main body tube 1313 of the harmonica tube 131 may be substantially parallel to the bottom wall of the battery housing. Since one side of the first current collector tube 110 facing the bottom wall of the battery housing is substantially parallel to the battery housing, and the angle between the main body tube 1313 of the harmonica tube 131 and the first bent section 1311 is substantially equal to 120 degrees, and the first bent section 1311 is substantially perpendicular to the first connection surface, therefore, the angle between the first connection surface and the bottom wall of the battery housing is substantially equal to 60 degrees. The first current collector tube 110 may be in the shape of a regular triangular prism, a rhombic prism, or other prismatic shapes, which is convenient for the material selection and processing of the first current collector tube 110 and can reduce the manufacturing cost of the water cooling system 100. The present application example does not limit the specific shape of the first current collector tube 110.
[0083] Based on the water cooling system 100 provided by the above example, an arc is formed at the connection between the first bent section 1311 and the main body tube 1313. And / or, an arc is formed at the connection between the second bent section 1312 and the main body tube 1313.
[0084] In the water cooling system 100 provided by the present application example, an arc may be formed only at the connection between the first bent section 1311 and the main body tube 1313, or an arc may be formed only at the connection between the second bent section 1312 and the main body tube 1313, or an arc may be formed at the connection between the first bent section 1311 and the main body tube 1313, and an arc may also be formed at the connection between the second bent section 1312 and the main body tube 1313.
[0085] The connection between the first bent section 1311 and the main body pipe 1313 forms an arc, which can reduce the loss of the condensate during the process of reaching the first bent section 1311 via the first manifold 110, and improve the heat dissipation efficiency of the water cooling system 100. The connection between the second bent section 1312 and the main body pipe 1313 forms an arc, which can reduce the loss of the condensate during the process of reaching the second bent section 1312 via the second manifold 120, and improve the heat dissipation efficiency of the water cooling system 100.
[0086] Based on the foregoing, the flow path of the condensate in the harmonica tube assembly 130 can be in a "U" shape. Exemplarily, it can be achieved that the flow path of the condensate in the harmonica tube assembly 130 is in a "U" shape by setting that the harmonica tube assembly 130 includes a first harmonica tube group 132, a second harmonica tube group 133 and a connecting manifold 134. Next, the specific structure of the harmonica tube assembly 130 will be described.
[0087] Based on the water cooling system 100 provided in the above example, Figure 4 This is a schematic structural diagram of another perspective of the water cooling system provided in the example of the present application. Please refer to Figure 3 And Figure 4 The first manifold 110 and the second manifold 120 are located on the same side of the harmonica tube assembly 130. The harmonica tube assembly 130 may further include a first harmonica tube group 132, a second harmonica tube group 133 and a connecting manifold 134. The first harmonica tube group 132 includes a water inlet and a sub-outlet. The second harmonica tube group 133 includes a sub-inlet and an outlet. The connecting manifold 134 is provided on a side of the first harmonica tube group 132 away from the first manifold 110.
[0088] The water inlet is connected to the first manifold 110. The sub-outlet is connected to the connecting manifold 134 at a first position of the connecting manifold 134. The sub-inlet is connected to the manifold at a second position of the connecting manifold 134. The outlet is connected to the second manifold 120. The first position and the second position are spaced apart.
[0089] The shape of the connecting manifold 134 may be similar to the shapes of the first manifold 110 and the second manifold 120. The connecting manifold 134 may be in the shape of a regular triangular prism, a rhombic prism, etc.
[0090] The first harmonica tube group 132 may include at least one first harmonica tube. The first harmonica tube may include a first bent section 1311 and a third bent section. One end of the first bent section 1311 facing the first manifold 110 is provided with a water inlet. The first harmonica tube is communicated with the first manifold 110 through the water inlet. One end of the third bent section facing the connecting manifold 134 is provided with a sub-outlet. The third bent section is communicated with the connecting manifold 134 through the sub-outlet.
[0091] The second harmonica tube group 133 may include at least one second harmonica tube, and the second harmonica tube may include a fourth bending section and a second bending section 1312. A sub-inlet is provided on the side of the fourth bending section facing the connecting manifold 134, and the first harmonica tube communicates with the connecting manifold 134 through the sub-inlet. An outlet is provided at one end of the second bending section 1312 facing the second manifold 120, and the second bending section 1312 communicates with the second manifold 120 through the outlet.
[0092] The flow direction of the condensate in the first harmonica tube is opposite to the flow direction of the condensate in the second harmonica tube.
[0093] The number of the first harmonica tubes and the number of the second harmonica tubes may be the same or different, and the present application example does not make specific restrictions on this.
[0094] When the first manifold 110 and the second manifold 120 are located at the same end of the harmonica tube assembly 130, the connecting manifold 134 may be located at one end of the first harmonica tube group 132 away from the first manifold 110 and the second manifold 120.
[0095] The first manifold 110 and the second manifold 120 may be two independent manifolds. The first manifold 110 and the second manifold 120 may also be formed by processing one manifold, and the present application example does not make specific restrictions on the implementation manners of the first manifold 110 and the second manifold 120.
[0096] The condensate may enter the first harmonica tube group 132 from the first manifold 110 through the inlet, enter the connecting manifold 134 from the sub-outlet of the first harmonica tube group 132, enter the second harmonica tube group 133 from the sub-inlet through the connecting manifold 134, enter the second manifold 120 from the outlet of the second harmonica tube group 133, and finally flow out of the water cooling system 100. At this time, the flow path of the condensate in the water cooling system 100 may be in a "U" shape.
[0097] Based on the water cooling system 100 provided by the above example, the condensate may sequentially enter the first harmonica tube group 132 from the first manifold 110 through the inlet, enter the connecting manifold 134 from the sub-outlet of the first harmonica tube group 132, enter the second harmonica tube group 133 from the sub-inlet through the connecting manifold 134, enter the second manifold 120 from the outlet of the second harmonica tube group 133, and finally flow out of the water cooling system 100, improving the usage efficiency of the condensate.
[0098] Based on the water cooling system 100 provided by the above example, Figure 5 For Figure 4 the partial enlarged schematic diagram at A in Figure 4 Please refer to Figure 5, the water cooling system 100 may further include a partition component 135 disposed between the first manifold 110 and the second manifold 120. One end of the partition component 135 is connected to the first manifold 110, and the other end of the partition component 135 is connected to the second manifold 120. The partition component 135 partitions the first manifold 110 and the second manifold 120.
[0099] Since the water cooling system 100 further includes a partition component 135 for partitioning the first manifold 110 and the second manifold 120, condensate can enter the first mouthpiece tube group 132 from the first manifold 110 via the water inlet, enter the connecting manifold 134 from the sub-water outlet of the first mouthpiece tube group 132, enter the second mouthpiece tube group 133 from the sub-water inlet via the connecting manifold 134, enter the second manifold 120 from the water outlet of the second mouthpiece tube group 133, and finally flow out of the water cooling system 100. At this time, the flow path of the condensate in the water cooling system 100 can be in a "U" shape.
[0100] Based on the different numbers of the first mouthpiece tube group 132 and the second mouthpiece tube group 133, the partition component 135 can be located at different positions of the mouthpiece tube assembly 130.
[0101] Exemplarily, when the number of the first mouthpiece tubes is greater than the number of the second mouthpiece tubes, the installation position of the partition component 135 can be closer to the first mouthpiece tube group 132 compared to the entire mouthpiece tube assembly 130.
[0102] When the number of the first mouthpiece tubes is less than the number of the second mouthpiece tubes, the installation position of the partition component 135 can be closer to the second mouthpiece tube group 133 compared to the entire mouthpiece tube assembly 130.
[0103] When the number of the first mouthpiece tubes is equal to the number of the second mouthpiece tubes, the installation position of the partition component 135 can be set closer to the center line of the mouthpiece tube assembly 130 compared to the entire mouthpiece tube assembly 130.
[0104] The partition component 135 may include one partition member, or the partition component 135 may also include a plurality of partition members. The specific implementation manner of the partition component 135 in this application is not limited, as long as the partition component 135 can partition the first manifold 110 and the second manifold 120.
[0105] In summary, by providing the partition component 135, one manifold can be partitioned into the first manifold 110 and the second manifold 120, which can improve the assembly efficiency of the water cooling system 100 and reduce the manufacturing cost of the water cooling system 100.
[0106] Based on the water cooling system 100 provided in the above example, please refer to Figure 5, the partition assembly 135 may include a first partition member 1351 and a second partition member 1352 that are spaced apart, and the first partition member 1351 may be disposed closer to the water inlet relative to the second partition member 1352.
[0107] The first partition member 1351 may be disposed closer to the water inlet relative to the second partition member 1352, and the second partition member 1352 may be disposed closer to the water outlet relative to the first partition member 1351.
[0108] The first partition member 1351 may be disposed as close as possible to the water inlet to reduce the possibility that condensate accumulates between the first partition member 1351 and the water inlet and cannot flow. As long as it is ensured that the first partition member 1351 does not affect the first mouthpiece tube group 132 during the welding process with the first manifold 110.
[0109] The second partition member 1352 may be disposed as close as possible to the water outlet to reduce the possibility that condensate accumulates between the second partition member 1352 and the water outlet and cannot flow. As long as it is ensured that the second partition member 1352 does not affect the second mouthpiece tube group 133 during the welding process with the second manifold 120.
[0110] In summary, by providing the first partition member 1351 and the second partition member 1352, and disposing the first partition member 1351 closer to the water inlet relative to the second partition member 1352, the distance between the first partition member 1351 and the water inlet can be reduced, and the possibility that condensate accumulates between the first partition member 1351 and the water inlet and cannot flow can be reduced. The second partition member 1352 is disposed closer to the water outlet relative to the first partition member 1351, which can reduce the distance between the second partition member 1352 and the water outlet and reduce the possibility that condensate accumulates between the second partition member 1352 and the water outlet and cannot flow.
[0111] Based on the water cooling system 100 provided in the above example, the number of mouthpiece tubes 131 included in the first mouthpiece tube group 132 is a first value, the number of mouthpiece tubes 131 included in the second mouthpiece tube group 133 is a second value, the ratio of the first value to the second value is 5 / 7, and the partition assembly 135 is disposed between the first mouthpiece tube group 132 and the second mouthpiece tube group 133.
[0112] By setting the ratio of the first value to the second value to 5 / 7 and disposing the partition assembly 135 between the first mouthpiece tube group 132 and the second mouthpiece tube group 133, the flow resistance of the condensate in the water cooling system 100 can be made smaller, thereby improving the heat dissipation efficiency of the water cooling system 100.
[0113] Finally, it should be noted that the above embodiments are only specific implementation manners of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions within the technical scope disclosed in the present application should be covered by the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
