Abstract
Description
Technical Field
[0001] This invention relates to the field of controller technology, specifically to a liquid cooling component, a controller assembly, and a vehicle thereof. Background Technology
[0002] The intelligent cockpit controller (cockpit domain controller / CDC) is the central computing brain of the intelligent vehicle cockpit, responsible for driving multiple screens, processing interactions, running in-vehicle systems and applications, and coordinating all electronic functions within the cockpit.
[0003] With the rapid development of the automotive industry, the demand for computing power in cockpit controllers is constantly increasing. Cockpit controllers integrate more functions, resulting in greater heat generation. Most existing technologies rely on passive cooling by the controller itself or fan cooling, which is insufficient to meet the cooling requirements, leading to poor heat dissipation. To address this, some products have incorporated liquid-cooled heat dissipation chambers on heat sinks. Coolant flows within these chambers to reduce the temperature of high-power chips, achieving heat dissipation. However, these liquid-cooled heat dissipation chambers have a simple structure, merely increasing the cross-sectional area of the liquid-cooled section corresponding to the high-power chip to improve heat dissipation. Their cooling capacity remains limited and cannot meet the increasingly demanding cooling needs of cockpit controllers. Summary of the Invention
[0004] In view of this, the present invention provides a liquid cooling component, a controller assembly and a vehicle thereof, to solve the problem that the heat dissipation capacity of existing liquid cooling heat dissipation chambers is still limited by simply increasing the cross-sectional area of the liquid cooling section corresponding to the high-power chip, and cannot meet the heat dissipation requirements of the cockpit controller with increasingly large heat generation.
[0005] This invention provides a liquid cooling assembly, comprising: The liquid cooling body is provided with a water outlet hole, a water inlet hole and a liquid cooling groove, and the liquid cooling groove is connected to the water outlet hole and the water inlet hole respectively. A liquid cooling cover plate is disposed on the end face of the liquid cooling body and is adapted to the liquid cooling groove. The liquid cooling cover plate and the liquid cooling groove together form a liquid cooling flow channel. In this embodiment, at the position corresponding to the heat dissipation component in the liquid cooling channel, at least one reinforcing part is provided along the flow direction of the coolant in the liquid cooling channel, and the reinforcing part bends back and forth at least twice along the flow direction of the coolant.
[0006] Beneficial effects: The liquid cooling channel is formed by the liquid cooling groove and liquid cooling cover plate of the liquid cooling body. At the position corresponding to the component to be scald, at least one reinforcing part is provided along the direction of liquid flow in the liquid cooling channel. The reinforcing part bends back and forth at least twice along the direction of liquid flow, so that the reinforcing part forms a structure with multiple bends. On the one hand, the effective heat exchange path of the liquid can be extended without increasing the area of the liquid cooling channel, thereby improving the utilization rate of the heat dissipation area. On the other hand, the liquid changes direction multiple times in the reinforcing part, which enhances the degree of turbulence and disturbance of the liquid, making the flow rate of the liquid faster, thereby enhancing the overall heat transfer coefficient. This allows the liquid to sweep more fully over the component to be scald, and the heat generated by the component can be carried away quickly and evenly, ensuring the heat dissipation efficiency of the liquid cooling heat dissipation chamber and meeting the heat dissipation requirements of the cockpit controller with increasingly large heat generation.
[0007] In one optional embodiment, the reinforcing section includes a first reinforcing segment, a first bending segment, a second reinforcing segment, a second bending segment, and a third reinforcing segment arranged sequentially. The projections of the first reinforcing segment, the second reinforcing segment, and the third reinforcing segment along the direction perpendicular to the flow of the coolant coincide, and the sum of their areas along the direction perpendicular to the flow of the coolant is equal to the cross-sectional area of other locations in the liquid cooling channel in that direction. The first bending segment and the second bending segment are centrally symmetrically distributed.
[0008] Beneficial effects: By setting the reinforcing section as a first reinforcing segment, a first bending segment, a second reinforcing segment, a second bending segment, and a third reinforcing segment, the overlapping projections of the first, second, and third reinforcing segments along the direction perpendicular to the coolant flow mean that the lengths of the first, second, and third reinforcing segments on the liquid cooling channel are all the same. This ensures that the coolant flow time remains consistent when flowing through the first, second, and third reinforcing segments, avoiding localized overheating caused by excessively fast or slow flow. Furthermore, the uniform length facilitates processing and molding, improving product reliability. The sum of the areas along the direction perpendicular to the coolant flow equals the cross-sectional area of other positions in the liquid cooling channel in that direction. This means that the total area of the first, second, and third reinforcing segments on the liquid cooling channel is equal to the cross-sectional area of the altered portion of the liquid cooling channel. In other words, the size of the liquid cooling channel is not increased. The first, second, and third reinforcing segments are rationally set without increasing the area of the liquid cooling channel.
[0009] In one alternative implementation, the first, second, and third reinforcing sections all have the same cross-sectional area in the liquid cooling channel.
[0010] Beneficial effects: By ensuring that the cross-sectional areas of the first, second, and third reinforcing sections are all the same, the flow resistance of the coolant is the same when it flows through the first, second, and third reinforcing sections. This avoids the coolant flow being affected by different flow resistances when it flows through the first, second, and third reinforcing sections, effectively ensuring a uniform flow distribution of the coolant in the liquid cooling channel and improving the smoothness of the coolant flow.
[0011] In one optional embodiment, the liquid cooling channel near the water outlet is provided with a water outlet guide, and the liquid cooling channel near the water inlet is provided with a water inlet guide. The cross-sectional area of the water outlet guide gradually decreases along the flow direction of the coolant, and the cross-sectional area of the water inlet guide gradually increases along the flow direction of the coolant.
[0012] Beneficial effects: By setting an outlet guide at the outlet of the liquid cooling channel, the cross-sectional area of the outlet guide gradually decreases along the flow direction of the coolant, thereby pressurizing and accelerating the coolant and reducing turbulence and backflow at the outlet, making it easier for the coolant to flow out of the outlet. By setting an inlet guide at the inlet of the liquid cooling channel, the cross-sectional area of the inlet guide gradually increases along the flow direction of the coolant, thereby achieving a smooth introduction of the coolant. The combination of the outlet guide and the inlet guide makes the flow state of the coolant more stable and convenient to use.
[0013] In one optional embodiment, the bottom wall of the liquid cooling channel near the water outlet is provided with a water outlet arc-shaped part, the shape of which is adapted to the shape of the water outlet guide part; and the bottom wall of the liquid cooling channel near the water inlet is provided with a water inlet arc-shaped part, the shape of which is adapted to the shape of the water inlet guide part.
[0014] Beneficial effects: The shapes of the inlet and outlet water passages are generally circular, which allows for better adaptation to the piping. The bottom wall of the liquid cooling channel is generally flat. An inlet arc-shaped section is set on the bottom wall of the liquid cooling channel at the inlet water passage. The curvature of the inlet arc-shaped section can be adapted to the curvature of the inlet water passage, thus allowing the coolant to flow smoothly into the liquid cooling channel. Similarly, an outlet arc-shaped section is set on the bottom wall of the liquid cooling channel at the outlet water passage. The curvature of the outlet arc-shaped section can be adapted to the curvature of the outlet water passage, thus allowing the coolant to flow smoothly out of the outlet water passage, thereby improving the flow performance of the coolant in the liquid cooling channel.
[0015] In one optional embodiment, a water outlet nozzle is provided on the water outlet through hole, and the water outlet through hole is connected to the water outlet nozzle through a first sealing structure. A water inlet nozzle is provided on the water inlet through hole, and the water inlet through hole is connected to the water inlet nozzle through a second sealing structure.
[0016] Beneficial effects: By installing a water outlet nozzle on the water outlet through-hole, the water outlet nozzle can be better connected to the water outlet pipe. The water outlet through-hole is connected to the water outlet nozzle through the first sealing structure, which makes the water outlet nozzle better sealed and prevents water leakage. Similarly, by installing a water inlet nozzle on the water inlet through-hole, the water inlet nozzle can be better connected to the water inlet pipe. The water inlet through-hole is connected to the water inlet nozzle through the first sealing structure, which makes the water inlet nozzle better sealed and prevents water leakage.
[0017] In one optional embodiment, at least one heat-conducting boss is provided on the end face of the liquid cooling body away from the liquid cooling groove, and the heat-conducting boss is suitable for applying heat-conducting adhesive for heat conduction.
[0018] Beneficial effects: By installing thermally conductive protrusions on the back of the liquid cooling body, with each protrusion corresponding to a component to be cooled, and applying thermally conductive adhesive to the protrusions, heat can be dissipated from the back of the liquid cooling assembly, further improving the heat dissipation effect.
[0019] The present invention also provides a controller assembly, including the above-described liquid cooling component, and further comprising: Upper shell; The antenna assembly is mounted on the end face of the liquid cooling assembly and is located on one side; First circuit component; Second circuit component; Lower housing; First connection structure; Second connection structure; In this configuration, along the first direction, the first connecting structure sequentially penetrates the liquid cooling assembly and the first circuit assembly, and is connected to the upper housing; the second connecting structure sequentially penetrates the lower housing and the second circuit assembly, and is connected to the liquid cooling assembly; the first direction is the height direction of the liquid cooling assembly.
[0020] Beneficial effects: By disassembling the controller assembly into multiple parts, the structure is simple, facilitating maintenance and replacement. The first connecting structure passes through the liquid cooling component and the first circuit component, connecting them to the upper housing. This locks the upper housing, liquid cooling component, and first circuit component into a single unit, ensuring a tight fit between them, improving heat dissipation efficiency, reducing assembly gaps, and enhancing structural rigidity and vibration resistance. The second connecting structure passes through the lower housing and the second circuit component, connecting them to the liquid cooling component. This locks the lower housing, the second circuit component, and the liquid cooling component into a single unit, ensuring a tight fit between them, improving heat dissipation efficiency. This improves thermal conductivity, reduces assembly gaps, and enhances structural rigidity and vibration resistance. Furthermore, the combination of these two elements allows for the separate fixing of the first and second circuit components above and below the liquid-cooled assembly, resulting in a more compact, layered fixing structure. This avoids interference and electromagnetic interference between the first and second circuit components, improving electrical reliability. Since neither the first nor the second connection structure is exposed on the upper housing, the controller assembly also offers excellent waterproofing. By placing the antenna assembly on one side of the liquid-cooled assembly, away from the strong electrical interference on the first and second circuit components in the central area, the operational reliability of the antenna assembly is improved.
[0021] In one optional embodiment, a plurality of upper reinforcing ribs are provided on the end face of the upper housing near the first circuit assembly, and the plurality of upper reinforcing ribs enclose to form a first space, the first space being suitable for mounting the first circuit assembly; a plurality of liquid cooling reinforcing ribs are provided on the end face of the liquid cooling assembly near the second circuit assembly, and the plurality of liquid cooling reinforcing ribs enclose to form a second space, the second space being suitable for mounting the second circuit assembly, and / or; Several reinforcing ribs are provided on the end face of the lower housing near the second circuit assembly. The reinforcing ribs together form a heat dissipation space. The second circuit assembly includes a second circuit body, a second core module, and a second interface module. The second core module and the second interface module are spaced apart on the end face of the second circuit body. The heat dissipation space is adapted to the second core module and is filled with thermally conductive adhesive.
[0022] Beneficial effects: By installing several upper reinforcing ribs on the bottom surface of the upper housing, the upper reinforcing ribs enclose and form a first space, which can accommodate the first circuit component, enhancing the structural strength of the upper housing, improving its resistance to deformation, preventing shaking and displacement, facilitating assembly positioning, and improving assembly efficiency; by setting several liquid cooling reinforcing ribs on the bottom surface of the liquid cooling component, the liquid cooling reinforcing ribs form a second space, which can accommodate the second circuit component, allowing for the positioning and installation of the second circuit component and realizing the partitioned arrangement of components; by installing lower reinforcing ribs on the top surface of the lower housing, the strength of the lower housing is enhanced, while forming a closed heat dissipation space. The heat dissipation space is filled with thermally conductive adhesive, which can effectively reduce thermal resistance, improve the heat dissipation effect of the core module, and ensure the long-term stable operation of the intelligent cockpit controller.
[0023] The present invention also provides a vehicle including the controller assembly as described above.
[0024] Beneficial effects: Since a vehicle including the above-mentioned controller assembly has the same effects as the controller assembly, it will not be described in detail here. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0029] The following is combined with Figures 1 to 9 The following describes embodiments of the present invention.
[0030] This invention provides a liquid cooling assembly 3, comprising: The liquid cooling body 31 is provided with a water outlet hole 312, a water inlet hole 311 and a liquid cooling groove, and the liquid cooling groove is connected to the water outlet hole 312 and the water inlet hole 311 respectively. The liquid cooling cover plate 32 is disposed on the end face of the liquid cooling body 31 and is adapted to the liquid cooling groove. The liquid cooling cover plate 32 and the liquid cooling groove together form a liquid cooling flow channel 35. In this embodiment, at the position corresponding to the heat dissipation component in the liquid cooling channel 35, at least one reinforcing part 351 is provided along the flow direction of the coolant in the liquid cooling channel 35, and the reinforcing part 351 bends back and forth at least twice along the flow direction of the coolant.
[0031] Specifically, a water outlet hole 312, a water inlet hole 311, and a liquid cooling groove are installed on the liquid cooling body 31. The installation positions of the water outlet hole 312 and the water inlet hole 311 can be set according to actual needs. For example, the water outlet hole 312 and the water inlet hole 311 can be installed on the same side wall or different side walls of the liquid cooling body 31. In this embodiment, the water outlet hole 312 and the water inlet hole 311 are both installed on the same side wall of the liquid cooling component 3, which is convenient for processing and connecting pipelines. The water outlet hole 312 and the water inlet hole 311 are both circular in shape, which is convenient for connecting pipelines. When the water outlet hole 312 and the water inlet hole 311 are both installed on the same side wall of the liquid cooling component 3, the shape of the liquid cooling groove is designed as a U-shaped structure, the liquid cooling cover plate 32 is installed on the liquid cooling groove of the liquid cooling body 31, and sealed with sealant. The liquid cooling groove and the liquid cooling cover plate 32 together form a liquid cooling flow channel 35.
[0032] In addition, at the position corresponding to the heat dissipation component in the liquid cooling channel 35, at least one reinforcing part 351 is provided along the liquid flow direction of the liquid cooling channel 35. The reinforcing part 351 bends back and forth at least twice along the liquid flow direction. It can be understood that the number of reinforcing parts 351 and the number of times the reinforcing part 351 bends back and forth along the liquid flow direction can be set according to actual needs. In this embodiment, the number of reinforcing parts 351 is one, and the number of times the reinforcing part 351 bends back and forth along the liquid flow direction is two, so that the reinforcing part 351 in the liquid cooling channel... The continuous bends formed on the 35 section, along with the reinforcement 351, extend the effective heat exchange path of the coolant without increasing the area of the liquid cooling channel 35, thereby improving the utilization rate of the heat dissipation area. Furthermore, the coolant undergoes multiple reversals within the reinforcement 351, enhancing turbulence and disturbance, increasing its flow rate, and thus improving the overall heat transfer coefficient. This allows the coolant to more thoroughly sweep over the components to be cooled, enabling the heat generated by these components to be carried away quickly and evenly, improving heat dissipation efficiency and meeting the increasingly demanding heat dissipation requirements of the cockpit controller. It should be noted that in this embodiment, the component to be cooled is the corresponding first circuit component 2 within the controller assembly.
[0033] See Figure 2 As shown, in one embodiment, the reinforcing section 351 includes a first reinforcing section 3511, a first bending section 3512, a second reinforcing section 3513, a second bending section 3514, and a third reinforcing section 3515 arranged sequentially. The projections of the first reinforcing section 3511, the second reinforcing section 3513, and the third reinforcing section 3515 along the direction perpendicular to the flow of the coolant coincide, and the sum of their areas along the direction perpendicular to the flow of the coolant is equal to the cross-sectional area of other locations of the liquid cooling channel 35 in that direction. The first bending section 3512 and the second bending section 3514 are centrally symmetrically distributed.
[0034] Specifically, such as Figure 2As shown, the arrows within the liquid cooling channel 35 indicate the flow direction of the liquid coolant. The positions of the reinforcing sections 351 are marked with dashed lines. The first reinforcing section 3511, the second reinforcing section 3513, and the third reinforcing section 3515 are all separated by dashed lines. The coincidence of the projections of the first reinforcing section 3511, the second reinforcing section 3513, and the third reinforcing section 3515 along the direction perpendicular to the liquid flow means that the lengths of the first reinforcing section 3511, the second reinforcing section 3513, and the third reinforcing section 3515 on the liquid cooling channel 35 are all the same, so that when the liquid flows through the first reinforcing section 3511, the second reinforcing section 3513, and the third reinforcing section 3515, the flow of the liquid is... The movement time is kept consistent to avoid local overheating caused by being too fast or too slow, and the same length makes it easy to process and shape, improving the reliability of the product; the sum of the areas perpendicular to the direction of cold liquid flow is equal to the cross-sectional area of other positions of the liquid cooling channel 35 in this direction. This means that the total area of the first reinforcing section 3511, the second reinforcing section 3513, and the third reinforcing section 3515 on the liquid cooling channel 35 is equal to the cross-sectional area of the changed part of the liquid cooling channel 35. That is, without increasing the size of the liquid cooling channel 35, the first reinforcing section 3511, the second reinforcing section 3513, and the third reinforcing section 3515 are reasonably set without increasing the area of the liquid cooling channel 35.
[0035] On the other hand, in this embodiment, the depths of the first reinforcing section 3511, the second reinforcing section 3513, and the third reinforcing section 3515 in the liquid cooling channel 35 remain unchanged, that is, they are the same as the depths of the liquid cooling channel 35.
[0036] See Figure 2 As shown, in one embodiment, the first reinforcing section 3511, the second reinforcing section 3513, and the third reinforcing section 3515 all have the same cross-sectional area on the liquid cooling channel 35.
[0037] Specifically, since the cross-sectional areas of the first reinforcing section 3511, the second reinforcing section 3513, and the third reinforcing section 3515 are all the same in the liquid cooling channel 35, the flow resistance of the coolant when flowing through the first reinforcing section 3511, the second reinforcing section 3513, and the third reinforcing section 3515 is the same. This avoids the coolant flow being affected by different flow resistances when flowing through the first reinforcing section 3511, the second reinforcing section 3513, and the third reinforcing section 3515, effectively ensuring that the flow rate of the coolant is uniformly distributed in the liquid cooling channel 35 and improving the smoothness of the coolant flow.
[0038] See Figure 2 As shown, in one embodiment, the reinforcing part 351 is provided on the liquid cooling channel 35 near the water outlet 312 or on the liquid cooling channel 35 near the water inlet 311.
[0039] Specifically, when the reinforcing part 351 is installed on the liquid cooling channel 35 near the water outlet 312 or near the water inlet 311, the main channel of the liquid cooling channel 35 is free of complex bends and extends straight, which can effectively reduce the resistance of the coolant in the liquid cooling channel 35. The bends are concentrated at the water outlet 312 or the water inlet 311, making the stamping process simpler. When the reinforcing part 351 is installed on the liquid cooling channel 35 near the water outlet 312, the flow velocity of the cold liquid increases when it flows to the first reinforcing section 3511, the second reinforcing section 3513 and the third reinforcing section 3515 because their cross-sectional areas are small, which can quickly discharge the cold liquid after heat exchange and heating. When the reinforcing part 351 is installed on the liquid cooling channel 35 near the water inlet 311, the cold liquid circulates back and forth twice in the first reinforcing section 3511, the second reinforcing section 3513 and the third reinforcing section 3515, which prolongs the heat exchange time with the heat-dissipating component under the condition of a fixed total heat exchange area, resulting in higher heat exchange efficiency.
[0040] See Figure 1 and Figure 2 As shown, in one embodiment, the liquid cooling channel 35 near the water outlet 312 is provided with a water outlet guide 353, and the liquid cooling channel 35 near the water inlet 311 is provided with a water inlet guide 352. The cross-sectional area of the water outlet guide 353 gradually decreases along the flow direction of the cold liquid, and the cross-sectional area of the water inlet guide 352 gradually increases along the flow direction of the cold liquid.
[0041] Specifically, a water outlet guide 353 is provided at one end of the liquid cooling channel 35 near the water outlet hole 312. The cross-sectional area of the water outlet guide 353 gradually decreases along the flow direction of the coolant. Due to the gradual decrease in the size of the water outlet guide 353, the coolant is pressurized and accelerated, reducing turbulence and backflow at the water outlet hole 312, making it easier for the coolant to flow out from the water outlet hole 312. A water inlet guide 352 is provided at one end of the liquid cooling channel 35 near the water inlet hole 311. The cross-sectional area of the water inlet guide 352 gradually increases along the flow direction of the coolant, realizing the smooth introduction of the coolant. Through the coordinated arrangement of the water outlet guide 353 and the water inlet guide 352, the flow state of the coolant is more stable and easier to use.
[0042] In this embodiment, the water outlet guide 353 is a right trapezoid, and the right-angled side of the right trapezoid can be adapted to the outer side of the liquid cooling channel 35. The water inlet guide 352 is also a right trapezoid, and the right-angled side of the right trapezoid can be adapted to the outer side of the liquid cooling channel 35, thereby enabling convenient and quick processing of the liquid cooling channel 35.
[0043] Further, see Figure 2As shown, the water outlet guide 353 and the water inlet guide 352 have the same shape and structure, and are arranged symmetrically along the center of the liquid cooling channel 35. By uniformly planning the structural shape and size of the water outlet guide 353 and the water inlet guide 352, it is easy to manufacture by stamping.
[0044] See Figure 1 and Figure 2 As shown, in one embodiment, the bottom wall of the liquid cooling channel 35 near the water outlet hole 312 is provided with a water outlet arc-shaped portion 355, which is adapted to the shape of the water outlet guide portion 353. The bottom wall of the liquid cooling channel 35 near the water inlet hole 311 is provided with a water inlet arc-shaped portion 354, which is adapted to the shape of the water inlet guide portion 352.
[0045] Specifically, the bottom wall of the liquid cooling channel 35 near the water outlet hole 312 is configured as the water outlet arc-shaped part 355 and the bottom wall near the water inlet hole 311 is configured as the water inlet arc-shaped part 354. Since the water outlet hole 312 and the water inlet hole 311 are both circular, the curvature of the water outlet arc-shaped part 355 matches the curvature of the water outlet hole 312, and the curvature of the water inlet arc-shaped part 354 matches the curvature of the water inlet hole 311, so that the coolant can flow smoothly out of the water outlet hole 312 and into the water inlet hole 311. In addition, the bottom wall of the outlet arc section 355 is inclined downward along the flow direction of the cold liquid, and the bottom wall of the inlet arc section 354 is inclined upward along the flow direction of the cold liquid, so that the air bubbles in the liquid cooling channel 35 can be discharged smoothly, effectively avoiding the problem of air blockage caused by air accumulation, ensuring that the heat exchange area of the liquid cooling channel 35 is fully utilized, and the inlet and outlet of the cold liquid in the liquid cooling channel 35 is smoother and more efficient, thus improving the circulation efficiency of the cold liquid.
[0046] See Figure 1 As shown, in one embodiment, a water outlet nozzle 34 is provided on the water outlet through hole 312, and the water outlet through hole 312 is connected to the water outlet nozzle 34 through a first sealing structure. A water inlet nozzle 33 is provided on the water inlet through hole 311, and the water inlet through hole 311 is connected to the water inlet nozzle 33 through a second sealing structure.
[0047] Specifically, both the first and second sealing structures are used for sealing, and both are made of sealant. A water outlet nozzle 34 is installed on the water outlet hole 312, allowing for better connection to the water outlet pipe. The water outlet hole 312 is connected to the water outlet nozzle 34 through the first sealing structure, ensuring a better seal and preventing leakage. A water inlet nozzle 33 is installed on the water inlet hole 311, allowing for better connection to the water inlet pipe. The water inlet hole 311 is connected to the water inlet nozzle 33 through the first sealing structure, ensuring a better seal and preventing leakage. Furthermore, both the water inlet nozzle 33 and the water outlet nozzle 34 have two adhesive grooves on their outer walls where they connect to the water inlet hole 311 and the water outlet hole 312, respectively, to ensure a tight seal after connection. It is understood that the water outlet 34 and water inlet 33 provided in this embodiment are both pipe fittings, which facilitate the connection of the water outlet pipe and the water inlet pipe.
[0048] See Figure 3 As shown, in one embodiment, at least one heat-conducting boss 315 is provided on the end face of the liquid cooling body 31 facing away from the liquid cooling groove. The heat-conducting boss 315 is suitable for applying heat-conducting adhesive for heat conduction.
[0049] Specifically, at least one thermally conductive protrusion 315 is installed on the back of the liquid-cooled body 31. The number of thermally conductive protrusions 315 can be arranged according to actual needs. Thermally conductive adhesive is applied to the thermally conductive protrusions 315. The thermally conductive adhesive can effectively fill the assembly gap between the bottom wall of the liquid-cooled assembly 3 and the component to be cooled, reduce the interface thermal resistance, and allow the heat from the component to be cooled to be quickly transferred to the liquid-cooled flow channel 35 and carried away by the coolant, thereby improving the heat dissipation efficiency. At the same time, the thermally conductive adhesive can also play a role in buffering and shock absorption, as well as electrical insulation, avoiding vibration damage to the device and the risk of conductive short circuits, thus improving the overall reliability and stability of the device. It should be noted that the component to be cooled in this embodiment is the second circuit component 4 within the controller assembly.
[0050] See Figures 1 to 9 As shown, the present invention also provides a controller assembly, including the liquid cooling component 3 described above, and further including: Upper shell 1; Antenna assembly 6 is disposed on the end face of liquid cooling assembly 3 and located on one side; First circuit component 2; Second circuit component 4; Lower housing 5; First connection structure 7; Second connection structure 8; In this configuration, along the first direction, the first connecting structure 7 passes through the liquid cooling assembly 3 and the first circuit assembly 2 in sequence and is connected to the upper housing 1. The second connecting structure 8 passes through the lower housing 5 and the second circuit assembly 4 in sequence and is connected to the liquid cooling assembly 3. The first direction is the height direction of the liquid cooling assembly 3.
[0051] Specifically, the first direction is the height direction of the liquid cooling component 3, marked as Y. In this embodiment, the first connection structure 7 is a plurality of first bolts. The bottom end face of the upper housing 1 is provided with corresponding upper liquid cooling component connection holes 72 and first circuit connection holes 71. The liquid component is installed with first through holes corresponding to the first bolts, and the first circuit component 2 is installed with second through holes corresponding to the first bolts. The first through holes and the second through holes are staggered. By passing through the first through holes and the second through holes respectively, and connecting them to the first circuit connection holes 71 and the upper liquid cooling component connection holes 72 respectively, the independent positioning and installation of the first circuit component 2 and the liquid cooling component 3 can be achieved, avoiding positional interference between the first circuit component 2 and the liquid cooling component 3, improving assembly accuracy and structural compactness, and facilitating later individual maintenance and disassembly.
[0052] Similarly, the second connection structure 8 provided in this embodiment consists of several second bolts. The bottom end face of the liquid cooling component 3 is equipped with a second circuit connection hole 81 and a lower housing connection hole 82. The second circuit component 4 is equipped with a third through hole corresponding to the second bolt, and the lower housing 5 is equipped with a fourth through hole corresponding to the second bolt. The third through hole and the fourth through hole are staggered. By passing several second bolts through the third through hole and the fourth through hole respectively, and connecting them to the lower housing connection hole 82 and the second circuit connection hole 81 respectively, the lower housing 5 and the second circuit component 4 are independently positioned and installed, avoiding positional interference between the lower housing 5 and the second circuit component 4, improving assembly accuracy and structural compactness, and facilitating later individual maintenance and disassembly. Meanwhile, through the cooperation of the first connecting structure 7 and the second connecting structure 8, the first circuit component 2 and the second circuit component 4 can be fixed above and below the liquid cooling component 3 respectively. The layered fixing structure is more compact, avoiding interference and electromagnetic interference between the first circuit component 2 and the second circuit component 4, improving electrical reliability. Moreover, neither the first connecting structure 7 nor the second connecting structure 8 is exposed on the end face of the upper housing 1 away from the first circuit component 2, so that water cannot flow in from the end face of the upper housing 1 away from the first circuit component 2, thus giving the controller assembly in this embodiment excellent waterproof effect.
[0053] On the other hand, by placing the antenna assembly 6 on one side of the liquid-cooled assembly 3, away from the strong electrical interference of the first circuit assembly 2 and the second circuit assembly 4 in the middle area, the operational reliability of the antenna assembly 6 is improved.
[0054] See Figure 1 , Figure 2 and Figure 5 As shown, in one embodiment, a stepped portion 36 is provided on the end face of the liquid cooling component 3 near the first circuit component 2, and at least one limiting member 361 is provided on the stepped portion 36, the limiting member 361 being used to abut against the side wall of the antenna component 6.
[0055] Specifically, a stepped portion 36 is formed on the upper surface of the liquid cooling component 3. The stepped portion 36 and the upper surface of the liquid cooling component 3 form a step shape, so that the installation area of the antenna component 6 is planned on the upper surface of the liquid cooling component 3, which facilitates assembly. By setting at least one limiting member 361, the limiting member 361 abuts against the side wall of the antenna component 6, making the antenna component 6 more firmly installed on the liquid cooling component 3.
[0056] See Figure 2 As shown, in this embodiment, an antenna connection hole 362 is provided on the stepped portion 36. The antenna connection hole 362 facilitates the wires inside the antenna assembly 6 to pass through the liquid cooling body 31 of the liquid cooling assembly 3 and connect to the second circuit assembly 4 below the liquid cooling assembly 3.
[0057] See Figures 1 to 3 As shown, in one embodiment, the liquid cooling component 3 is provided with a circuit board connection hole 313, which is used to facilitate the connection between the first circuit component 2 and the second circuit component 4.
[0058] See Figures 5 to 8 As shown, in one embodiment, the upper housing 1 has a plurality of upper reinforcing ribs 11 on the end face near the first circuit assembly 2, and the plurality of upper reinforcing ribs 11 enclose to form a first space 12, the first space 12 being suitable for mounting the first circuit assembly 2; the liquid cooling assembly 3 has a plurality of liquid cooling reinforcing ribs 314 on the end face near the second circuit assembly 4, and the plurality of liquid cooling reinforcing ribs 314 enclose to form a second space 37, the second space 37 being suitable for mounting the second circuit assembly 4, and / or; The lower housing 5 has several reinforcing ribs 51 on its end face near the second circuit assembly 4. The reinforcing ribs together form a heat dissipation space 52. The second circuit assembly 4 includes a second circuit body 41, a second core module 42, and a second interface module. The second core module 42 and the second interface module are spaced apart on the end face of the second circuit body 41. The heat dissipation space 52 is adapted to the second core module 42 and is filled with thermally conductive adhesive.
[0059] Specifically, in this embodiment, there are four upper reinforcing ribs 11, four lower reinforcing ribs 51, and four liquid-cooling reinforcing ribs 314. The four upper reinforcing ribs 11 are installed on the bottom surface of the upper housing 1 to form a first space 12. The first space 12 is rectangular and is adapted to the first circuit assembly 2. The four upper reinforcing ribs 11 enhance the structural strength of the upper housing 1, improve its resistance to deformation, prevent shaking and displacement, facilitate assembly positioning, and improve assembly efficiency. The four lower reinforcing ribs 51 are installed on the top surface of the lower housing 5 to form a heat dissipation space 52. The heat dissipation space 52 is used to adapt to the second core module 42 in the second circuit assembly 4 to conduct heat to the second core module 42. The four lower reinforcing ribs 51 enhance the strength of the lower housing 5. The heat dissipation space 52 is filled with thermally conductive adhesive, which can effectively reduce thermal resistance, improve the heat dissipation effect of the second circuit assembly 4, and ensure the long-term stable operation of the controller assembly. Similarly, the four liquid-cooling reinforcing ribs 314 form a second space 37. The second space 37 is adapted to the second circuit assembly 4 and is used to position and install the second circuit assembly 4 to achieve partitioned arrangement of components.
[0060] See Figures 5 to 9 As shown, in one embodiment, a first fixing structure 91 is provided on the end face of the upper housing 1 away from the first circuit assembly 2, a second fixing structure 92 is provided on the end face of the lower housing 5 away from the second circuit assembly 4, and a third fixing structure 93 is provided around the side wall of the liquid cooling assembly 3. The first fixing structure 91, the second fixing structure 92 and the third fixing structure 93 are all suitable for fixing the controller assembly.
[0061] Specifically, the first fixing structure 91 consists of a first positioning post and a first positioning hole, which are installed at intervals on the top end face of the upper housing 1; the second fixing structure 92 consists of a second positioning post and a second positioning hole, which are installed at intervals on the bottom end face of the lower housing 5; the third fixing structure 93 consists of a third positioning post and a third positioning hole, which are installed at intervals on the side wall of the liquid cooling component 3 and are not on the same side as the antenna component 6; through the first fixing structure 91, the second fixing structure 92 and the third fixing structure 93, the assembled controller assembly can be connected and fixed in multiple directions, which facilitates assembly. It should be noted that the number of the first fixing structure 91, the second fixing structure 92, and the third fixing structure 93 can be set in multiples according to actual needs. Since the antenna assembly 6 is installed on one side of one side of the liquid-cooled body 31, and the interfaces of the first circuit assembly 2 and the second circuit assembly 4 need to be exposed on the other side, the third fixing structure 93 is set on the side wall of the liquid-cooled body 31, and its orientation is different from that of the side wall where the antenna assembly 6 is installed. The reasonable layout of the structure makes the assembled controller assembly structure more compact.
[0062] See Figure 5As shown, in one embodiment, the first circuit assembly 2 includes a first circuit body, a first core module, and a first interface module. The first core module is mounted on the first circuit body, and the first interface module is mounted on one side of the first circuit body. Similarly, the second circuit assembly 4 includes a second circuit body 41, a second core module 42, and a second interface module. The second core module 42 is mounted on the second circuit body 41, and the second interface module is mounted on one side of the second circuit body 41. It is understood that the first core module and the second core module 42 both refer to related functional devices such as chips, video, cameras, Bluetooth / WIFI, etc., and users can set them according to actual functional requirements.
[0063] See Figure 6 As shown, in one embodiment, the upper reinforcing rib 11 divides the bottom end face of the upper housing 1 into a first space 12 and a third space 13. The first space 12 is used to adapt the first core module on the first circuit body, and the third space 13 is used to adapt the first interface module on the first circuit body. The third space 13 is exposed to the outside, which facilitates the connection of the first interface module with external electrical appliances.
[0064] See Figure 7 As shown, in one embodiment, the liquid cooling reinforcing rib 314 divides the bottom end face of the liquid cooling body 31 into a second space 37 and a fourth space 38. The second space 37 is used to adapt the second core module 42 on the first circuit body, and the fourth space 38 is used to adapt the second interface module on the second circuit body 41. The fourth space 38 is exposed to the outside, which facilitates the connection of the second interface module with external electrical appliances.
