Description

Technical Field

[0001] This application relates to the field of vehicle power technology, specifically to a power supply device. Background Technology

[0002] In existing automotive power supply water cooling technologies, the water channels mostly adopt a single three-dimensional or flat design. Due to the influence of the core layout, a three-dimensional water channel design is required to achieve the desired heat dissipation effect. However, the design of a three-dimensional water channel can lead to abrupt changes in cross-section, affecting the overall pressure drop of the water channel. Furthermore, the presence of eddies and trapped air phenomena can also hinder the heat dissipation of components. Therefore, it is necessary to enhance heat transfer technology, improve the flow field of the cooling medium, and optimize the liquid cooling channels to improve the heat dissipation effect on components. Utility Model Content

[0003] In view of this, this application provides a power supply device, wherein the turbulence-inducing element in the power supply device can reduce the generation of eddy currents and trapped air, and has a better heat dissipation effect on the components.

[0004] This application provides a power supply device, which includes: a housing, a three-dimensional water channel, and a baffle. The housing has a cavity for housing components. The three-dimensional water channel is disposed within the cavity and is close to the components for heat dissipation. The three-dimensional water channel has a flow channel for distributing cooling fluid. The baffle is located within the flow channel and extends along the extension direction of the flow channel, and the baffle is stepped.

[0005] Furthermore, the three-dimensional waterway includes a convex portion and a concave portion, the convex portion being connected to the concave portion, the flow-disrupting element having a protrusion corresponding to the position of the convex portion, and the flow-disrupting element having a notch corresponding to the concave portion.

[0006] Furthermore, the distance between the protrusion of the turbulence-disrupting element and the protrusion of the three-dimensional waterway, as well as the distance between the recess of the turbulence-disrupting element and the recess of the three-dimensional waterway, are equal.

[0007] Furthermore, the flow-disrupting component includes a main body and a plurality of flow-disrupting portions. The main body extends along the extension direction of the flow channel, and the plurality of flow-disrupting portions are spaced apart around the outer periphery of the main body.

[0008] Furthermore, the flow-disrupting part is a flow-disrupting fin, and the plurality of flow-disrupting fins are arranged at intervals around the outer periphery of the main body, and the flow-disrupting fins extend along the extension direction of the flow channel.

[0009] Furthermore, the flow-dispersing part is a flow-dispersing column, and the plurality of flow-dispersing columns are arranged around the outer periphery of the main body.

[0010] Furthermore, the power supply device also includes a mounting component connected to one end of the flow disruptor, for installing the flow disruptor within the flow channel of the three-dimensional waterway.

[0011] Furthermore, the power supply device also includes a connector, and there are multiple flow deflectors, which are spaced apart and connected to the connector, which is connected to the mounting member.

[0012] Furthermore, the three-dimensional water channel includes a first heat dissipation section, a second heat dissipation section, and a third heat dissipation section. The two ends of the first heat dissipation section are respectively connected to the second heat dissipation section and the third heat dissipation section. The second heat dissipation section and the third heat dissipation section are arranged in parallel and opposite to each other. The flow-dispersing component includes a first flow-dispersing section, a second flow-dispersing section, and a third flow-dispersing section. The two ends of the first flow-dispersing section are respectively connected to the second flow-dispersing section and the third flow-dispersing section. The first flow-dispersing section is arranged corresponding to the first heat dissipation section, the second flow-dispersing section is arranged corresponding to the second heat dissipation section, and the third flow-dispersing section is arranged corresponding to the third heat dissipation section.

[0013] Furthermore, the power supply device also includes a cooling component, which includes a cooling element and a cooling plate. The cooling element is used to cool the cooling plate, and the cooling plate is attached to the outer surface of the housing to dissipate heat from the housing and the three-dimensional water channel.

[0014] In this application, the three-dimensional water channel is located close to the component. The three-dimensional water channel has a flow channel for distributing cooling fluid. When the cooling fluid flows within the flow channel, the heat generated by the component during operation is transferred to the three-dimensional water channel and then carried out of the flow channel by the cooling fluid, thereby achieving heat dissipation for the component. Furthermore, in the power supply device provided in this application, the baffle is located within the flow channel, extends along the direction of the flow channel, and is stepped. When the cooling fluid flows through the baffle, the stepped baffle can change the flow path of the cooling fluid, mitigating eddies or trapped air within the flow channel, thereby improving the heat dissipation effect of the three-dimensional water channel on the component. Specifically, if the water channel structure of the three-dimensional water channel is flat, eddies and trapped air may occur at the inlet where the cooling fluid enters the flow channel. The stepped baffle within the flow channel can alleviate the generation of eddies. If the waterway structure of the three-dimensional waterway is uneven, eddies and air trapping phenomena are likely to occur at the points where the cross-section of the flow channel changes. The step-shaped turbulence-disrupting component can disrupt the eddy region and eliminate the risk of air trapping. In addition, compared with solutions such as setting protruding nails in the flow channel, the solution of this application does not require drafting inside the flow channel, simplifying the flow channel design and helping to save on the manufacturing cost of the three-dimensional waterway.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0030] In existing automotive power supply water cooling technologies, the water channels mostly adopt a single three-dimensional or flat design. Due to the influence of the core layout, a three-dimensional water channel design is required to achieve the desired heat dissipation effect. However, the design of a three-dimensional water channel can lead to abrupt changes in cross-section, affecting the overall pressure drop of the water channel. Furthermore, the presence of eddies and trapped air phenomena can also hinder the heat dissipation of components. Therefore, it is necessary to enhance heat transfer technology, improve the flow field of the cooling medium, and optimize the liquid cooling channels to improve the heat dissipation effect on components.

[0031] Specifically, in single-layer or flat-plate water channels, the flow field is often improved by adding protruding studs inside the channel. However, due to limitations in draft direction and structural design, this method cannot be effectively applied to three-dimensional water channels. In existing three-dimensional water channel designs, the channel cross-section changes multiple times due to component placement, leading to a larger overall pressure drop. Vortex or trapped air phenomena may exist at the undulating points of the channel, adversely affecting the heat dissipation of components.

[0032] Understandably, in the terminology of this application, "three-dimensional water channel" refers to a heat dissipation water channel with a three-dimensional structure. The three-dimensional water channel has multiple heat dissipation surfaces, and components can be disposed on the outer periphery or surface of the heat dissipation surfaces. The heat of the components is transferred to the cooling medium through the three-dimensional water channel, and then the heat is transferred to the external environment.

[0033] Please see Figure 1 , Figure 2 and Figure 4 This application provides a power supply device 100, which includes: a housing 110, a three-dimensional water channel 120, and a baffle 131. The housing 110 has a receiving cavity 111 for housing components. The three-dimensional water channel 120 is disposed in the receiving cavity 111 and is close to the components for heat dissipation. The three-dimensional water channel 120 has a flow channel 121 for distributing cooling fluid. The baffle 131 is located in the flow channel 121 and extends along the extension direction of the flow channel 121, and the baffle 131 is stepped.

[0034] Understandably, the components are located within the accommodating cavity 111 and are positioned close to the three-dimensional water channel 120.

[0035] Optionally, the cooling fluid may be, but is not limited to, water.

[0036] Optionally, the component may be, but is not limited to, a diode, a metal-oxide-semiconductor insulated-gate field-effect transistor, etc.

[0037] Understandably, the flow-disrupting element 131 is stepped, which can be a series of steps that are alternately stacked along the height direction of the three-dimensional waterway 120 to form a structure with multiple protrusions 1311 and notches 1312.

[0038] In this embodiment, the three-dimensional water channel 120 is located close to the component. The three-dimensional water channel 120 has a flow channel 121 for distributing cooling fluid. When the cooling fluid flows within the flow channel 121, the heat generated by the component during operation is transferred to the three-dimensional water channel 120 and then carried out of the flow channel 121 by the cooling fluid, thereby achieving heat dissipation for the component. Furthermore, in the power supply device 100 provided in this embodiment, the baffle 131 is located within the flow channel 121. The baffle 131 extends along the extension direction of the flow channel 121 and is stepped. When the cooling fluid flows through the baffle 131, the stepped baffle 131 can change the flow path of the cooling fluid, thereby mitigating eddies or trapped air within the flow channel 121 and improving the heat dissipation effect of the three-dimensional water channel 120 on the component. Specifically, if the water channel structure of the three-dimensional water channel 120 is flat, eddies and trapped air may occur at the inlet of the cooling fluid entering the flow channel 121. Setting a stepped baffle 131 within the flow channel 121 can alleviate the generation of eddies. If the water channel structure of the three-dimensional water channel 120 is uneven, eddies and trapped air are prone to occur at the points where the cross-section of the flow channel 121 changes. The stepped baffle 131 can disrupt the eddy region and eliminate the risk of trapped air. Furthermore, compared to solutions such as setting protruding studs within the flow channel 121, the solution in this embodiment does not require drafting inside the flow channel 121, simplifying the design of the flow channel 121 and helping to save on the manufacturing cost of the three-dimensional water channel 120.

[0039] Optionally, the three-dimensional water channel 120 further includes an inlet (not shown) and an outlet (not shown), the inlet and the outlet being spaced apart in the three-dimensional water channel 120 and respectively communicating with the flow channel 121. In the three-dimensional water channel 120, cooling fluid enters the flow channel 121 through the inlet, circulates, and then flows out of the flow channel 121 through the outlet. In this application, the positions of the inlet and outlet are not specifically limited.

[0040] Optionally, the three-dimensional waterway 120 and the flow-disrupting element 131 are separate structures; in other words, the three-dimensional waterway 120 and the flow-disrupting element 131 are detachably connected.

[0041] In this embodiment, the three-dimensional water channel 120 is positioned close to the component, and the baffle 131 is detachably connected to the three-dimensional water channel 120. Firstly, when the water channel structure of the three-dimensional water channel 120 is uneven and has a cross-sectional difference, a baffle 131 that varies with the undulations of the water channel structure can be selected and installed in the three-dimensional water channel 120. The baffle 131 can disrupt the vortex region, reducing the risk of vortex phenomena and air trapping phenomena inside the three-dimensional water channel 120, thereby improving the heat dissipation effect on the component. Secondly, when the position of the component positioned close to the three-dimensional water channel 120 is adjusted or changed, a baffle 131 with a different shape can be selected and installed in the three-dimensional water channel 120, so that the baffle 131 corresponds to the component with a high heat generation, further improving the heat dissipation effect on the heat-generating component. In summary, the flow-disrupting element 131 with a specific curved structure can be selected according to the waterway structure of the three-dimensional waterway 120, so that the flow-disrupting element 131 can be set at the position where eddies may occur in the flowway 121, thereby reducing the generation of eddies or trapped air. In addition, the relative position of the flow-disrupting element 131 and the three-dimensional waterway 120 can be determined according to the relative position of the components and the three-dimensional waterway 120, so that the flow-disrupting element 131 can be set for components with more heat generation, thereby improving the heat dissipation effect.

[0042] Optionally, the three-dimensional waterway 120 and the turbulence-disrupting component 131 can be detachably connected in a manner that is, but not limited to, snap-fit ​​connection, bolt connection, etc.

[0043] Please see also Figure 3 In some embodiments, the three-dimensional waterway 120 includes a protrusion 1221 and a recess 1222, the protrusion 1221 being connected to the recess 1222, the flow-disrupting member 131 having a protrusion 1311 corresponding to the position of the protrusion 1221, and the flow-disrupting member 131 having a notch 1312 corresponding to the recess 1222.

[0044] Understandably, along the height direction of the three-dimensional waterway 120, the protrusion 1221 is provided corresponding to the protrusion 1311, and the recess 1222 is provided corresponding to the notch 1312.

[0045] Understandably, the protrusion 1311 and the recess 1312 make the spoiler 131 stepped.

[0046] In this embodiment, when the cooling fluid flows along the extension direction of the flow channel 121, the cooling fluid may generate eddy currents and / or trapped air phenomena near the protrusion 1221 due to the cross-sectional difference. That is, the interface difference formed by the protrusion 1221 and the concave portion 1222 will cause eddy currents. In this embodiment, the flow deflector 131 is disposed close to the first cover plate 122, and the position of the flow deflector 131 corresponding to the protrusion 1221 protrudes in a direction close to the protrusion 1221. That is, the protrusion 1311 of the flow deflector 131 is disposed corresponding to the protrusion 1221, and the position of the flow deflector 131 corresponding to the concave portion 1222 protrudes in a direction close to the concave portion 1222. That is, the notch 1312 of the flow deflector 131 is disposed corresponding to the concave portion 1222. In other words, the curved structure of the flow deflector 131 corresponds to the change of the flow channel 121 of the three-dimensional water channel 120, so that when the cooling fluid flows through the flow deflector 131, the flow deflector 131 can destroy the vortex region, play a role in mitigating the generation of vortex phenomenon and trapped air phenomenon, thereby improving the heat dissipation effect on the components.

[0047] In some embodiments, the three-dimensional waterway 120 includes a first cover plate 122, a first side plate 123, a second cover plate 124, and a second side plate 125 connected end to end. The first cover plate 122, the first side plate 123, the second cover plate 124, and the second side plate 125 form the flow channel 121. The first cover plate 122, the first side plate 123, and the second side plate 125 cooperate with each other to form the protrusion 1221 and the recess 1222. The protrusion 1221 protrudes from the... The first cover plate 122 is away from the surface of the flow channel 121. The recess 1222 is recessed in the surface of the first cover plate 122 away from the flow channel 121. The flow deflector 131 is disposed close to the first cover plate 122. The flow deflector 131 protrudes in the direction close to the protrusion 1221 corresponding to the position of the protrusion 1221 and forms a protrusion 1311. The flow deflector 131 is recessed in the direction close to the recess 1222 corresponding to the position of the recess 1222 and forms a notch 1312.

[0048] Understandably, the first side plate 123 and the second side plate 125 respectively form the outer side plate and the inner side plate of the flow channel 121.

[0049] Understandably, the first cover plate 122 forms the upper cover plate of the flow channel 121, and the second cover plate 124 forms the lower cover plate of the flow channel 121.

[0050] In this embodiment, the first cover plate 122, the first side plate 123, the second cover plate 124, and the second side plate 125 form the flow channel 121 to facilitate the flow of cooling fluid and dissipate heat from the components. Furthermore, the first cover plate 122, the first side plate 123, and the second side plate 125 cooperate to form the protrusion 1221 and the recess 1222. The protrusion 1221 protrudes from the surface of the first cover plate 122 facing away from the flow channel 121, and the recess 1222 is recessed into the surface of the first cover plate 122 facing away from the flow channel 121. In other words, the protrusion 1221 is recessed into the surface of the first cover plate 122 facing the flow channel 121. The recess 1222 can avoid the structure of the components within the accommodating cavity 111, thereby improving the space utilization rate inside the power supply device 100. However, correspondingly, the protrusion 1221 protrudes from the surface of the first cover plate 122 away from the flow channel 121, and the recess 1222 is recessed into the surface of the first cover plate 122 away from the flow channel 121. Therefore, along the arrangement direction of the first cover plate 122 and the second cover plate 124, the flow channel 121 has a cross-sectional change. In other words, along the arrangement direction of the first cover plate 122 and the second cover plate 124, the distance between the first cover plate 122 and the second cover plate 124 is constantly changing. Therefore, when the cooling fluid flows along the extension direction of the flow channel 121, the cooling fluid may generate eddy currents and / or trapped air phenomena near the position between the protrusion 1221 and the recess 1222 due to the cross-sectional difference. In this embodiment, the flow deflector 131 is disposed close to the first cover plate 122, and the flow deflector 131 protrudes in the direction of the protrusion 1221 to form a protrusion 1311, and the flow deflector 131 is recessed in the direction of the recess 1222 to form a notch 1312. In other words, the curved structure of the flow deflector 131 corresponds to the change of the flow channel 121 of the three-dimensional water channel 120, so that when the cooling fluid flows through the flow deflector 131, the flow deflector 131 can destroy the vortex region, play a role in mitigating the generation of vortex phenomenon and trapped air phenomenon, thereby improving the heat dissipation effect on the components.

[0051] Optionally, there may be multiple protrusions 1221, which are spaced apart on the first cover plate 122 to avoid structural issues with the components inside the accommodating cavity 111 and improve the space utilization inside the power supply device 100.

[0052] Optionally, there may be multiple recesses 1222, multiple protrusions 1311, and multiple notches 1312.

[0053] Understandably, in the terminology of this application, "multiple" means two or more, and can be, but is not limited to, two, three, four, six, eight, ten, or twelve, etc.

[0054] Optionally, the second cover plate 124 is detachably connected to the housing 110, the first side plate 123 and the second side plate 125 respectively.

[0055] In this embodiment, the second cover plate 124 is detachably connected to the housing 110, the first side plate 123, and the second side plate 125, respectively. During the assembly of the power supply device 100, the second cover plate 124 is first separated from the housing 110, the first side plate 123, and the second side plate 125, respectively, so that the flow-disrupting component 131 enters the flow channel 121 from the side of the second cover plate 124 and is installed on the three-dimensional water channel 120. Further, after the second cover plate 124 is connected to the housing 110, the first side plate 123, and the second side plate 125, cooling fluid is injected into the flow channel 121.

[0056] In some embodiments, the distance between the protrusion 1311 of the baffle 131 and the protrusion 1221 of the three-dimensional waterway 120, and the distance between the recess 1312 of the baffle 131 and the recess 1222 of the three-dimensional waterway are equal. In other words, the distance between the baffle 131 and the surface of the first cover plate 122 facing the flow channel 121 is equal.

[0057] Understandably, the distance between the protrusion 1311 of the turbulence-disrupting element 131 and the protrusion 1221 of the three-dimensional waterway 120 is the distance between the surface of the protrusion 1311 facing the first cover plate 122 and the surface of the protrusion 1221 facing the flow channel 121.

[0058] Understandably, the distance between the recess 1312 of the flow deflector 131 and the recess 1222 of the three-dimensional waterway is the distance between the surface of the recess 1312 facing the first cover plate 122 and the surface of the recess 1222 facing the flow channel 121.

[0059] In this embodiment, the distance between the protrusion 1311 of the baffle 131 and the protrusion 1221 of the three-dimensional water channel 120, and the distance between the recess 1312 of the baffle 131 and the recess 1222 of the three-dimensional water channel are equal. In other words, the distance between the baffle 131 and the surface of the first cover plate 122 facing the flow channel 121 is equal. Furthermore, the plane containing each part of the baffle 131 is parallel or nearly parallel to the surface of the first cover plate 122 facing the flow channel 121. When the baffle 131 is disposed within the flow channel 121, it can adapt to the cross-sectional changes of the flow channel 121 to disrupt the vortex region within the flow channel 121, thereby mitigating vortex phenomena and air trapping phenomena, and ensuring the heat dissipation effect of the three-dimensional water channel 120 on the components.

[0060] Please see also Figure 5 In some embodiments, the flow-disrupting element 131 includes a main body 1313 and a plurality of flow-disrupting parts 1314. The main body 1313 extends along the extension direction of the flow channel 121, and the plurality of flow-disrupting parts 1314 are spaced apart around the outer periphery of the main body 1313.

[0061] Understandably, the main body 1313 extends along the extension direction of the flow channel 121 and forms the protrusion 1311 and the recess 1312.

[0062] In this embodiment, the turbulence-disrupting component 131 includes a main body 1313 and a plurality of turbulence-disrupting portions 1314. The plurality of turbulence-disrupting portions 1314 are spaced apart around the outer periphery of the main body 1313. The main body 1313 extends along the extension direction of the flow channel 121. When the cooling fluid flows through the turbulence-disrupting portions 1314, the stepped turbulence-disrupting portions 1314 can disrupt the vortex region within the flow channel 121, thereby mitigating the generation of vortex phenomena and trapped air phenomena. Furthermore, since the plurality of turbulence-disrupting portions 1314 are spaced apart around the outer periphery of the main body 1313, the plurality of turbulence-disrupting portions 1314 can increase the turbulence intensity when the cooling fluid flows through the turbulence-disrupting portions 1314, thereby enhancing the efficiency of heat transfer around the turbulence-disrupting portions 1314, and thus improving the heat dissipation efficiency of the three-dimensional water channel 120 for the components. Furthermore, the plurality of flow-deflecting sections 1314 can increase the time for cooling fluid to flow through the flow-deflecting sections 1314. The flow-deflecting element 131 has a better heat dissipation effect on the corresponding components. Therefore, according to the relative position of the flow-deflecting element 131 and the three-dimensional water channel 120, components with higher heat generation can be correspondingly arranged in areas with better heat dissipation effect. The flow-deflecting element 131 can also be flexibly selected according to the position of components with higher heat generation. In the power supply device 100 provided in this application, the three-dimensional water channel 120 and the flow-deflecting element 131 cooperate with each other to achieve a better heat dissipation effect on the components.

[0063] In some embodiments, the flow-disrupting portion 1314 is a flow-disrupting fin 1315, and the plurality of flow-disrupting fins 1315 are arranged at intervals around the outer periphery of the main body portion 1313, and the main body portion 1313 and the plurality of flow-disrupting fins 1315 extend along the extension direction of the flow channel 121.

[0064] In this embodiment, the plurality of turbulence-inducing fins 1315 are spaced apart around the outer periphery of the main body 1313. Both the main body 1313 and the plurality of turbulence-inducing fins 1315 extend along the extension direction of the flow channel 121. When the cooling fluid flows through the turbulence-inducing portion 1314, the stepped turbulence-inducing portion 1314 can disrupt the vortex region within the flow channel 121, thereby mitigating the generation of vortex phenomena and trapped air phenomena. Furthermore, the plurality of turbulence-inducing fins 1315, spaced apart around the outer periphery of the main body 1313, can increase the turbulence intensity when the cooling fluid flows through the turbulence-inducing portion 1314, thereby enhancing the efficiency of heat transfer around the turbulence-inducing portion 1314 and improving the heat dissipation efficiency of the three-dimensional water channel 120 for the components. Furthermore, since the turbulence section 1314 is provided with the turbulence fins 1315, the turbulence element 131 has a better heat dissipation effect on the corresponding components. Therefore, according to the relative position of the turbulence element 131 and the three-dimensional water channel 120, components with higher heat generation can be correspondingly arranged in areas with better heat dissipation effect. The turbulence element 131 can also be flexibly selected according to the position of components with higher heat generation. In the power supply device 100 provided in this application, the three-dimensional water channel 120 and the turbulence element 131 cooperate with each other to have a better heat dissipation effect on the components.

[0065] In some embodiments, the turbulence portion 1314 is a turbulence column, and the plurality of turbulence columns are arranged at intervals around the outer periphery of the main body portion 1313.

[0066] In this embodiment, the plurality of turbulence-disrupting columns are spaced apart around the outer periphery of the main body 1313. When the cooling fluid flows through the turbulence-disrupting section 1314, the stepped turbulence-disrupting section 1314 can disrupt the vortex region within the flow channel 121, thereby mitigating the generation of vortex phenomena and trapped air phenomena. Furthermore, the plurality of turbulence-disrupting columns spaced apart around the outer periphery of the main body 1313 can increase the turbulence intensity when the cooling fluid flows through the turbulence-disrupting section 1314, thereby enhancing the efficiency of heat transfer around the turbulence-disrupting section 1314 and improving the heat dissipation efficiency of the three-dimensional water channel 120 for the components. Furthermore, since the turbulence section 1314 is provided with the turbulence column, the turbulence member 131 has a better heat dissipation effect on the corresponding components. Therefore, according to the relative position of the turbulence member 131 and the three-dimensional water channel 120, components with higher heat generation can be correspondingly arranged in areas with better heat dissipation effect. The turbulence member 131 can also be flexibly selected according to the position of components with higher heat generation. In the power supply device 100 provided in this application, the three-dimensional water channel 120 and the turbulence member 131 cooperate with each other to have a better heat dissipation effect on the components.

[0067] Please see also Figure 6 and Figure 7 In some embodiments, the power supply device 100 further includes a mounting member 134, which is connected to one end of the flow disruptor 131 and is used to install the flow disruptor 131 onto the three-dimensional waterway 120.

[0068] In this embodiment, the mounting component 134 is connected to one end of the baffle 131 to install the baffle 131 on the three-dimensional water channel 120, thereby fixing the relative position of the baffle 131 and the three-dimensional water channel 120, so that the baffle 131 and the three-dimensional water channel 120 cooperate to have a better heat dissipation effect on the component.

[0069] Optionally, in some embodiments, the inner wall of the housing 110 has a mounting groove, and the mounting member 134 is engaged in the mounting groove to install the turbulence-disrupting member 131 on the three-dimensional waterway 120 and fix the relative position of the turbulence-disrupting member 131 and the three-dimensional waterway 120.

[0070] Please see also Figure 8 In some embodiments, there are multiple flow deflectors 131, which are spaced apart within the flow channel 121. The power supply device 100 also includes a connector 135, which is connected to the multiple flow deflectors 131 respectively.

[0071] Understandably, two adjacent spoilers 131 are connected by the coupling 135.

[0072] Understandably, the plurality of flow-disrupting elements 131 are arranged at intervals along the height direction of the three-dimensional waterway 120. In other words, the plurality of flow-disrupting elements 131 are arranged at intervals along the arrangement direction of the first cover plate 122 and the second cover plate 124.

[0073] In this embodiment, multiple flow-disrupting elements 131 are spaced apart within the flow channel 121, and the connecting element 135 connects the multiple flow-disrupting elements 131 respectively, so that the multiple flow-disrupting elements 131 form an integral structure. Therefore, only one mounting element 134 is needed to install the multiple flow-disrupting elements 131 into the flow channel 121 of the three-dimensional water channel 120, simplifying the installation process of the multiple flow-disrupting elements 131. Furthermore, along the arrangement direction of the first cover plate 122 and the second cover plate 124, the multiple flow-disrupting elements 131 are spaced apart within the flow channel 121. Firstly, the multiple flow-disrupting elements 131, in conjunction with the three-dimensional water channel 120, can effectively reduce eddy currents and air trapping phenomena within the flow channel 121, ensuring the heat dissipation effect of the three-dimensional water channel 120 on the components. Secondly, multiple flow-dissipating elements 131 are spaced apart along the arrangement direction of the first cover plate 122 and the second cover plate 124. The multiple flow-dissipating elements 131 can be arranged to correspond to different components along the height direction, so that the three-dimensional water channel 120 can dissipate heat from multiple components with high heat generation at the same time, which can further improve the heat dissipation effect of the three-dimensional water channel 120 on the components.

[0074] In some embodiments, the three-dimensional water channel 120 includes a first heat dissipation section 126, a second heat dissipation section 127, and a third heat dissipation section 128. The two ends of the first heat dissipation section 126 are respectively connected to the second heat dissipation section 127 and the third heat dissipation section 128. The second heat dissipation section 127 and the third heat dissipation section 128 are arranged in parallel opposite directions. The flow-dispersing component 131 includes a first flow-dispersing section 1316, a second flow-dispersing section 1317, and a third flow-dispersing section 1318. The two ends of the first flow-dispersing section 1316 are respectively connected to the second flow-dispersing section 1317 and the third flow-dispersing section 1318. The first flow-dispersing section 1316 is arranged corresponding to the first heat dissipation section 126, the second flow-dispersing section 1317 is arranged corresponding to the second heat dissipation section 127, and the third flow-dispersing section 1318 is arranged corresponding to the third heat dissipation section 128.

[0075] Understandably, in the height direction of the three-dimensional water channel 120, the orthographic projection of the first heat dissipation section 126 overlaps with the orthographic projection of the first turbulence section 1316, the orthographic projection of the second heat dissipation section 127 overlaps with the orthographic projection of the second turbulence section 1317, and the orthographic projection of the third heat dissipation section 128 overlaps with the orthographic projection of the third turbulence section 1318.

[0076] In this embodiment, the first heat dissipation section 126, the second heat dissipation section 127 and the third heat dissipation section 128 form a U-shaped structure, so that when the three-dimensional water channel 120 is disposed in the accommodating cavity 111, more components can be disposed on the outer periphery of the three-dimensional water channel 120 or on the inner side of the U-shaped structure, thereby improving the utilization rate of the three-dimensional water channel 120. Correspondingly, the first turbulence section 1316, the second turbulence section 1317, and the third turbulence section 1318 also form a U-shaped structure. The first turbulence section 1316 is set to correspond to the first heat dissipation section 126, the second turbulence section 1317 is set to correspond to the second heat dissipation section 127, and the third turbulence section 1318 is set to correspond to the third heat dissipation section 128. When the cooling fluid flows in the channel and passes through the turbulence member 131, the first turbulence section 1316, the second turbulence section 1317, and the third turbulence section 1318 can adapt to the structural changes of the first heat dissipation section 126, the second heat dissipation section 127, and the third heat dissipation section 128 to change the flow path of the cooling fluid, alleviate the vortex phenomenon or air trapping phenomenon in the channel, and thus improve the heat dissipation effect of the three-dimensional water channel 120 on the components.

[0077] Please see also Figure 9 In some embodiments, the power supply device 100 further includes a cooling component 140, which includes a cooling element (not shown) and a cooling plate 141. The cooling element is used to cool the cooling plate 141, and the cooling plate 141 is attached to the outer surface of the housing 110 to dissipate heat from the housing 110 and the three-dimensional water channel 120.

[0078] Optionally, the heat-conducting sheet 141 is a metal sheet. Specifically, the heat-conducting sheet 141 can be, but is not limited to, a silver sheet, a copper sheet, an aluminum sheet, etc.

[0079] Optionally, in some embodiments, the cooling element is disposed within the receiving cavity 111 of the power supply device 100; in other embodiments, the cooling element is disposed on the housing 110; and in still other embodiments, the cooling element is disposed outside the power supply device 100 and is separately disposed from the power supply device 100. In this application, the placement position of the cooling element is not limited.

[0080] Optionally, the refrigeration method of the refrigeration component includes, but is not limited to, at least one of thermoelectric refrigeration, vapor compression refrigeration, adsorption refrigeration, and magnetic refrigeration.

[0081] Optionally, the cooling plate 141 is attached to the outer surface of the housing 110 and disposed near the three-dimensional water channel 120.

[0082] In this embodiment, the cooling component is used to cool the cooling plate 141, which is attached to the outer surface of the housing 110. The cooling component cools the cooling plate 141 to reduce its temperature. Since the temperature of the cooling plate 141 is lower than that of the housing 110, it is beneficial to transfer the low temperature through the housing 110 to the cooling fluid, the turbulence-dissipating component 131, and then through the cooling fluid located in the turbulence-dissipating component 131 to the components, thereby reducing the temperature of the components and achieving the purpose of heat dissipation for the housing 110 and the three-dimensional water channel 120, so as to further meet the heat dissipation requirements of the components.
