DETAILED DESCRIPTION

[0030] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the following will be combined with the drawings in the embodiments of the present application to make a clear and complete description of the technical solutions in the embodiments of the present application. Obviously, the described embodiments are a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work belong to the scope of protection of the present application.

[0031] The following disclosure provides many different embodiments or examples for implementing different structures of the present application. For the purpose of simplifying the present application, the components and settings of specific examples are described in the following. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeatedly refer to numbers and / or letters in different examples. Such repetition is for the purpose of simplification and clarity, and it does not indicate the relationship between the various embodiments and / or settings discussed.

[0032] For the purpose of description, spatial relative terms can be used in the text to describe the relative position relationship or motion condition of one element or feature with respect to another element or feature as shown in the figure, such as "internal", "external", "inboard", "outboard", "under", "below", "on", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figure. For example, if the device in the figure is flipped over or the posture is changed or the motion state is changed, the directional indications will also change accordingly, for example: the element described as "under" or "below" another element or feature will be oriented as "above" or "above" another element or feature. Therefore, the example term "below" can include both up and down positions. The device can be additionally oriented (rotated 90 degrees or in other directions) and the spatial relative relationship descriptors used in the text are interpreted accordingly.

[0033] As Figures 1-3 As shown in the figure, the natural heat dissipation controller according to the embodiments of the present application includes a shell, the shell defines a mounting cavity, a mainboard 20 is arranged in the mounting cavity, a plurality of heat dissipation fins 12 are arranged on the shell, the plurality of heat dissipation fins 12 are arranged in a direction array with a first direction as a row and a second direction as a column, and the first direction is perpendicular to the second direction.

[0034] In detail, the shell defines a mounting cavity, and the main board 20 is arranged in the mounting cavity, so that the main board 20 is protected by the shell. The main board 20 generates heat during operation, and the heat is dissipated to the shell. The shell is provided with a plurality of heat dissipation fins 12. The array formed by the plurality of heat dissipation fins 12 helps to increase the heat dissipation surface area. Meanwhile, the grid formed by the spacing between the plurality of heat dissipation fins 12 helps to increase the air flow exchange efficiency, thereby further enhancing the heat exchange effect. Meanwhile, the heat dissipation fins 12 dissipate heat without excessively increasing the overall size of the naturally heat-dissipating controller, so that the size of the naturally heat-dissipating controller can be ensured to be not excessively large while maintaining good heat dissipation effect.

[0035] The first direction and the second direction are defined directions. The first direction can be the width direction of the shell, and the second direction is the length direction of the shell. Alternatively, the first direction can be the length direction of the shell, and the second direction is the width direction of the shell. Of course, the first direction can also be inclined to the width direction or the length direction of the shell, as long as the first direction is perpendicular to the second direction.

[0036] The heat dissipation fins 12 and the shell can be integrally formed, welded, or detachably connected. Preferably, the heat dissipation fins 12 and the shell are integrally formed. In this way, the connection strength of the heat dissipation fins 12 and the shell can be enhanced. Meanwhile, the integrally formed heat dissipation fins 12 and shell can reduce the thermal resistance at the interface between the heat dissipation fins 12 and the shell, so that heat can be more effectively conducted from the heat dissipation fins 12 to the shell, thereby improving the heat dissipation performance.

[0037] As shown in FIG. 1, Figure 4 According to the naturally heat-dissipating controller of the embodiment of the present application, the heat dissipation fins 12 include first fin portions 121. The first fin portions 121 are connected to the shell, and the plurality of first fin portions 121 are arranged in the same direction.

[0038] In detail, the heat dissipation fins 12 include first fin portions 121. The plurality of first fin portions 121, i.e., the first fin portions 121 of each heat dissipation fin 12, are arranged in the same direction. In this way, the contact area with air can be increased, and the heat exchange efficiency can be enhanced, so that heat can be more quickly dissipated to the surrounding environment. Meanwhile, the inclined arrangement can make the air flow more smooth, so that the turbulent flow can be reduced when the air flow passes through the first fin portions 121, thereby improving the air flow efficiency and being conducive to more uniform heat dissipation. In addition, compared with the vertically arranged first fin portions 121, the inclined arrangement can reduce the air flow resistance, reduce the accumulation of dust and debris, and improve the long-term reliability. Furthermore, the inclined first fin portions 121 can have a larger heat exchange area in a limited space, thereby having a better heat dissipation effect.

[0039] In a specific embodiment, the included angle between the first fin portions 121 and the shell is 45°.

[0040] In one specific embodiment, both the heat sink 14 and the heat sink fins 12 are made of aluminum or aluminum alloy.

[0041] In one specific embodiment, the thickness of the first wing 121 gradually decreases as it extends closer to the second wing 122 along the extension line, thereby improving heat conduction efficiency.

[0042] like Figure 4 As shown, in some embodiments, the heat dissipation fins 12 further include a second fin 122, which is connected to the end of the first fin 121 away from the housing, and the end face of the second fin 122 away from the housing is located in the same plane.

[0043] Understandably, the second fin 122 increases the heat dissipation area, which helps to dissipate heat more quickly and improves heat dissipation efficiency. The side of the second fin 122 away from the shell is located in the same plane, which makes the heat more evenly distributed on the surface of the entire heat dissipation fin 12, avoiding the problem of uneven heat dissipation caused by excessive local heat. At the same time, the second fin 122 is connected to the first fin 121, which increases the stability and strength of the overall structure of the heat dissipation fin 12 and can better resist external vibration and pressure.

[0044] In the thickness direction of the shell, that is, the third direction upward, the second fin 122 has a certain width and is spaced from the shell to facilitate airflow. The third direction, the first direction, and the second direction are all perpendicular to each other.

[0045] In some embodiments, the fixed end of the second wing 122 is connected to the first wing 121, and the free end of the second wing 122 is configured with a rounded corner structure, which can reduce the risk of users scratching their hands during assembly or subsequent maintenance.

[0046] In some embodiments, in the third direction, the thickness of the second fin 122 is less than the thickness of the first fin 121, wherein the first direction, the second direction, and the third direction are perpendicular to each other, which can increase the capacity of the heat dissipation fin 12 to contact the air, thereby improving the heat conduction efficiency.

[0047] like Figures 1-3 as well as Figure 7 As shown, in some embodiments, the housing includes a frame 13 and a heat sink 14 disposed on the front of the frame 13. The heat sink 14 and the frame 13 are detachably connected. Heat sink fins 12 are disposed on the side of the heat sink 14 facing away from the main board 20. A boss 141 is provided on the side of the heat sink 14 facing the main board 20. A heat-generating device 21 is provided on the main board 20. The boss 141 and the heat-generating device 21 abut against each other.

[0048] It can be understood that the setting of the boss 141 can increase the heat conduction efficiency between the heat generating device 21 and the heat dissipation plate 14, and can more effectively transfer heat to the external environment, avoiding overheating of the controller of natural heat dissipation; and the heat dissipation plate 14 and the frame 13 are detachably connected, which is convenient for processing and manufacturing, as well as daily cleaning and maintenance.

[0049] Among them, the heat generating device 21 on the mainboard 20 is usually a chipset, CPU and power module, etc., which will generate heat in work. In a specific embodiment, the heat generating device 21 is a wafer (integrated circuit chip) on the mainboard 20 as a heat generating device 21 and the boss 141 abuts. Among them, the heat generating device 21 and the boss 141 can be directly abutted or indirectly abutted, so as to realize the contact heat conduction.

[0050] In some embodiments, a heat-conducting elastic member is arranged between the boss 141 and the heat generating device 21.

[0051] It can be understood that by arranging the heat-conducting elastic member, the heat conduction between the boss 141 and the heat generating device 21 can be realized, and hard contact between the boss 141 and the heat generating device 21 can be avoided. At the same time, since the heat-conducting elastic member has elasticity, it can also compensate for the possible errors between the heat dissipation plate 14 and the frame 13 and the mainboard 20, so that one side of the boss 141 can be contacted, and the other side of the heat-conducting elastic member can be contacted with the heat generating device 21.

[0052] In a specific embodiment, the heat-conducting elastic member is a silica gel member, and other elastic and heat-conducting elastic materials can be selected as needed, which is not limited in the application.

[0053] In a specific embodiment, the design gap between the boss 141 and the heat generating device 21 is 0.1mm, and the thickness of the heat-conducting elastic member is 0.3mm.

[0054] As shown in Figure 3 , Figure 4 and Figure 7 In some embodiments, at least one first matching part 142 is arranged on the heat dissipation plate 14, and at least one second matching part 22 is arranged on the mainboard 20, the at least one second matching part 22 is arranged along the circumference of the heat generating device 21, and the first matching part 142 and the second matching part 22 are detachably connected.

[0055] In order to ensure that the boss 141 can be aligned with the heat generating device 21, at least one second matching part 22 is arranged on the heat generating device 21 in the circumferential direction, and the first matching part 142 and the second matching part 22 are used to position the boss 141 and the heat-conducting elastic part during assembly, so that the boss 141 and the heat-conducting elastic part are not separated due to the deformation of the main plate 20 or batch deviation.

[0056] When the number of the second matching parts 22 is more than one, the second matching parts 22 are arranged at intervals in the circumferential direction of the heat generating device 21, and the distance between the second matching parts 22 and the heat generating device 21 is closer than the distance between the edge of the main plate 20 and the heat generating device 21.

[0057] In some specific embodiments, the first matching part 142 and the second matching part 22 can be screw connection, lock connection, elastic connection and clamping connection, etc. The second matching part 22 can be rotatably arranged on the main plate 20, and the first matching part 142 and the second matching part 22 are connected by threads. When the first matching part 142 and the second matching part 22 are connected by lock connection, the connection can be realized by rotating, inserting and the like. In addition, an elastic structure can be arranged on one of the first matching part 142 or the second matching part 22, and a corresponding hole can be arranged on the other one, and the first matching part 142 and the second matching part 22 can be connected by pressing or extruding.

[0058] As shown in Figure 3 and Figure 4 According to the natural cooling controller of the present application, the side of the heat dissipation plate 14 away from the main plate 20 is provided with a baffle 143, the baffle 143 is located on one side of the array formed by the plurality of heat dissipation fins 12, and the baffle 143 extends in the first direction or the second direction.

[0059] In detail, the baffle 143 arranged on the heat dissipation plate 14 can guide the air flow, so that the air can exchange heat with the plurality of heat dissipation fins 12 as much as possible, thereby improving the heat dissipation efficiency. At the same time, the baffle 143 can also protect the plurality of heat dissipation fins 12 arranged in the array, so as to avoid the heat dissipation fins 12 from being broken and falling off. At the same time, the baffle 143 can also isolate the heat of the heat dissipation fins 12, so as to avoid the heat from being conducted to other working components. Therefore, by arranging the baffle 143, the air flow and heat distribution can be optimized, the heat dissipation effect is significantly improved, and the temperature of the natural cooling controller can be effectively reduced.

[0060] As shown in Figure 3 and Figure 5As shown, in some embodiments, the natural heat dissipation controller further comprises a first fastener, one end of the frame 13 facing the heat dissipation plate 14 is provided with a first connecting piece 131, the first connecting piece 131 is provided with a mounting hole 1311, the heat dissipation plate 14 is provided with a mounting column 144, the mounting column 144 is provided with a threaded hole configured as a blind hole, and the first fastener is simultaneously threaded into the mounting hole 1311 and the threaded hole.

Among them, by setting the mounting hole 1311 on the first connecting piece 131 and directly threading the first fastener, the installation process can be simplified, the number of tools required is reduced, the installation time is shortened, and the assembly between the heat dissipation plate 14 and the frame 13 is more compact, which helps to save space. The threaded hole is configured as a blind hole, which makes the connection between the heat dissipation plate 14 and the frame 13 more secure, reduces the risk of loosening, and ensures that the connection between the heat dissipation plate 14 and the frame 13 is more secure.

[0062] As shown in the figure, Figure 2 In some embodiments, the outer side wall of one side of the frame 13 is provided with a fixed plate 30, at least one end of the fixed plate 30 is provided with a second connecting piece 31 that exceeds the edge of the frame 13, and at least one second connecting piece 31 is provided with a third matching part 32.

[0063] In detail, the fixed plate 30 can enhance the stability of the frame 13 and prevent the frame 13 from shifting or deforming during use. By providing the second connecting piece 31 on the fixed plate 30, the third matching part 32 on the second connecting piece 31 can be used to stably connect with other components, so as to install and fix the natural heat dissipation controller in the case. The presence of the third matching part 32 allows the natural heat dissipation controller as a whole to be quickly disassembled and installed with the case, improving the convenience of use. The design of the second connecting piece 31 exceeding the edge of the frame 13 can facilitate the quick disassembly and installation of the natural heat dissipation controller as a whole with the case.

[0064] As shown in the figure, Figure 2 In one specific embodiment, both ends of the fixed plate 30 are provided with a second connecting piece 31, one of the second connecting pieces 31 is provided with a third matching part 32, and the other second connecting piece 31 is provided with a fourth matching part 33. The structures of the third matching part 32 and the fourth matching part 33 can be the same or different. For example, one of the third matching part 32 and the fourth matching part 33 can be a hole structure for fastening, and the other can be a guide groove for cooperating with the guide column of the case for guidance and positioning.

[0065] In a specific embodiment, the baffle 143 and the fixed plate 30 are respectively located on opposite sides of the heat dissipation plate 14.

[0066] As shown in Figure 1 , Figure 5 , Figure 6 and Figure 8 In some embodiments, the back of the frame 13 is provided with a back plate 40, and the third connecting piece 41 is vertically arranged on the back plate 40, and the third connecting piece 41 is attached to the inner wall of the frame 13 and connected by the second fastener.

[0067] In detail, the installation cavity formed by the shell can be closed by the arrangement of the back plate 40, which can reduce the possibility of dust entering. At the same time, the back plate 40 can provide additional support for the frame 13, prevent the frame 13 from deforming when subjected to external force, and make the load more evenly distributed to avoid local overload. At the same time, the third connecting piece 41 connected with the frame 13 can further enhance the connection strength and the support force of the frame 13.
