[0002] Rugged laptops are designed to withstand harsh environments. During the design phase, appropriate protective measures are taken against various factors affecting the performance of rugged laptops, such as system structure, electrical characteristics, and mechanical physical structure. They are also known as environmentally friendly rugged laptops. Currently, in special fields with relatively harsh environmental conditions such as ships, coastal areas, and oil exploration, rugged laptops have become a type of computer device that can meet the computing needs of special industries in different application scenarios due to their waterproof, dustproof, shockproof, drop-proof, corrosion-resistant, and portable features.

[0003] In terms of corrosion prevention, because rugged laptops are composed of components made of various different materials that are tightly fitted together, the potential difference between the different materials is large. In corrosive environments such as salt spray, galvanic corrosion is easily formed, which accelerates the corrosion of rugged laptops in such environments. Utility Model Content

[0004] In view of the above problems, this application provides a ruggedized laptop computer that can improve the corrosion resistance of the ruggedized laptop computer and slow down the corrosion rate of the ruggedized laptop computer.

[0005] According to one aspect of the embodiments of this application, a ruggedized laptop computer is provided, the ruggedized laptop computer including a screen assembly and a main body shell assembly; the screen assembly includes a screen shell assembly and a hinge, the rotating structure of the hinge is connected to the screen shell assembly through a first threaded fastener, the fixing structure of the hinge is connected to the main body shell assembly through a second threaded fastener, the rotating structure and the fixing structure are rotatably connected, so that the screen assembly and the main body shell assembly can rotate relative to each other; the hinge, the first threaded fastener and the second threaded fastener are all made of stainless steel, the screen shell assembly and the main body shell assembly are made of a different metal material than the hinge, and the hinge, the first threaded fastener and the second threaded fastener are all insulated from the screen shell assembly and the main body shell assembly.

[0006] In one alternative approach, both the rotating structure and the fixed structure are strip-shaped and are rotatably interlocked to form a rotating shaft. The opposite ends of the rotating structure and the fixed structure are connected to the screen housing assembly and the main unit housing assembly respectively by threaded fasteners.

[0007] In one alternative embodiment, the two ends of the rotating structure and the fixed structure that are opposite to each other are plate-shaped structures; a first insulating member is clamped and fixed between the plate-shaped structure of the rotating structure and the screen housing assembly, the first insulating member being used to isolate the screen housing assembly from the plate-shaped structure of the rotating structure; a second insulating member is clamped and fixed between the plate-shaped structure of the fixed structure and the main unit housing assembly, the second insulating member being used to isolate the main unit housing assembly from the plate-shaped structure of the fixed structure.

[0008] In one alternative embodiment, a window is provided on the screen housing assembly, the inside of the window is covered by a screen unit, the edge of the screen unit has a metal frame, and an annular conductive element is sandwiched between the metal frame and the inner wall of the window edge.

[0009] In one alternative approach, the conductive element is a waterproof conductive structure, and a first annular seal is also sandwiched between the screen unit and the inner wall of the window edge.

[0010] In one alternative embodiment, the screen housing assembly includes a first housing and a second housing, a window is formed on the first housing, the second housing is fastened to the first housing and a mounting cavity is formed between the second housing and the first housing, a screen unit is disposed in the mounting cavity, the screen unit is fixed on the first housing and covers the window, and an annular second seal is clamped between the first housing and the second housing.

[0011] In one alternative embodiment, the main unit housing has an isolated mounting cavity and a heat dissipation cavity. The mounting cavity contains a motherboard, and the heat dissipation cavity contains a heat sink. A heat-conducting component connects the heat sink and the motherboard, and the heat-conducting component is used to conduct heat from the motherboard to the heat sink. The main unit housing has ventilation holes at opposite ends of the heat dissipation cavity, and a fan is also installed in the heat dissipation cavity. The fan is used to blow out the heat absorbed by the heat sink through the ventilation holes.

[0012] In one alternative embodiment, a partition is provided inside the main unit housing, which divides the internal space of the main unit housing into an installation cavity and a heat dissipation cavity. A heat-conducting component seals through the partition and is connected to a heat sink. The heat sink and the heat-conducting component are made of a different type of metal material than the main unit housing and the partition. The heat sink is insulated from the inner wall of the heat dissipation cavity, and the heat-conducting component is insulated from the partition.

[0013] In one alternative approach, multiple heat dissipation fins are arranged side by side on the heat sink, with a distance of 1 to 2 millimeters between adjacent heat dissipation fins, and an insulating powder layer is sprayed onto the heat dissipation fins.

[0029] The embodiments of the technical solution of this application will now be described in detail with reference to the accompanying drawings. These embodiments are only used to more clearly illustrate the technical solution of this application and are therefore merely examples, and should not be used to limit the scope of protection of this application.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms “comprising” and “having”, and any variations thereof, in the specification, claims, and foregoing description of the drawings are intended to cover non-exclusive inclusion.

[0031] In the description of the embodiments of this application, technical terms such as "first" and "second" are used only to distinguish different objects and should not be construed as indicating or implying relative importance or implicitly specifying the number, specific order, or primary and secondary relationship of the indicated technical features. In the description of the embodiments of this application, "multiple" means two or more, unless otherwise explicitly defined.

[0032] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0033] In the description of the embodiments in this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A exists, A and B exist simultaneously, and B exists. In addition, the character " / " in this document generally indicates that the related objects before and after it have an "or" relationship.

[0034] In the description of the embodiments of this application, the term "multiple" refers to two or more (including two), similarly, "multiple sets" refers to two or more (including two sets), and "multiple pieces" refers to two or more (including two pieces).

[0035] In the description of the embodiments of this application, the technical terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on the embodiments of this application.

[0036] In the description of the embodiments of this application, unless otherwise expressly specified and limited, technical terms such as "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in the embodiments of this application can be understood according to the specific circumstances.

[0037] Different metallic elements have different electrode potentials. For example, iron and copper have positive electrode potentials, while magnesium and aluminum have negative electrode potentials. When metallic materials with different electrode potentials are placed in the same solution, galvanic corrosion easily occurs due to the potential difference between them, and the metal with the negative electrode potential corrodes first. Therefore, in corrosive environments such as salt spray, when components of different materials in a ruggedized laptop come into contact with each other, the components with the negative electrode potential are more likely to corrode.

[0038] To improve the corrosion resistance of ruggedized laptops, the outer casing components, such as the screen casing, the main body casing, and the hinges that allow relative rotation between the screen and main body casings, can all be made of the same metal material, such as aluminum alloy. Aluminum alloy, after surface treatment, is generally not easily corroded by salt spray. This ensures that even if the components are in contact, no potential difference will be generated, and it is also less prone to corrosion in corrosive environments.

[0039] However, during use, the hinge of a rugged laptop needs to rotate frequently to support the frequent opening and closing of the screen casing and the main body casing. Aluminum alloy has relatively low strength, making it difficult to guarantee the hinge's rotational performance. To address this, this application proposes a rugged laptop where, to prioritize the hinge's rotational performance and lifespan, both the hinge and the threaded fasteners used to mount and secure it are made of stainless steel. However, if the screen casing and main body casing were also made of stainless steel to improve corrosion resistance, the high density of stainless steel would significantly increase their weight, making the rugged laptop inconvenient to carry. Considering this issue, the screen casing and main body casing can be made of different metals such as aluminum alloy or magnesium alloy. In corrosive environments such as salt spray or acid spray, if the hinge and threaded fasteners are in direct contact with the screen casing and main body casing during assembly, they will experience galvanic corrosion due to the difference in electrode potential, further exacerbating the corrosion of the screen casing and main body casing, which have negative electrode potentials.

[0040] To improve the corrosion resistance of the screen and main unit casings, the hinges are insulated from both casings, ensuring that there is no potential difference between the hinges and threaded fasteners and the screen and main unit casings. This prevents galvanic corrosion between the hinges and the screen and main unit casings in corrosive environments such as salt spray, thereby slowing down the corrosion rate of the screen and main unit casings and improving the overall corrosion resistance of the reinforced laptop.

[0041] Please see Figure 1 , Figure 1 A perspective view of a ruggedized laptop computer 10 provided in an embodiment of this application is shown. The ruggedized laptop computer 10 includes a screen assembly 100 and a main unit housing 200. Please refer to the following... Figure 2 and Figure 3 , Figure 2 This illustration shows a structural diagram of the ruggedized laptop computer at the hinge, as provided in an embodiment of this application. Figure 3 An exploded view of the screen components is shown, such as... Figure 2-3 As shown, the screen assembly 100 includes a screen housing assembly 110 and a rotating shaft 120. The rotating structure 121 of the rotating shaft 120 is connected to the screen housing assembly 110 via a first threaded fastener 130a, and the fixing structure 122 of the rotating shaft 120 is connected to the main housing assembly 200 via a second threaded fastener 130b. The rotating structure 121 and the fixing structure 122 are rotatably connected, allowing the screen housing assembly 110 and the main housing assembly 200 to rotate relative to each other. The rotating shaft 120, the first threaded fastener 130a, and the second threaded fastener 130b are all made of stainless steel. The screen housing assembly 110 and the main housing assembly 200 are made of a different type of metal than the rotating shaft 120, and the rotating shaft 120, the first threaded fastener 130a, and the second threaded fastener 130b are all insulated from the screen housing assembly 110 and the main housing assembly 200.

[0042] A through hole can be made in the rotating structure 121 of the rotating shaft 120, and a threaded hole can be made inside the screen housing assembly 110. The first threaded fastener 130a is passed through the through hole and connected to the threaded hole to connect and fix the rotating structure 121 to the screen housing assembly 110. The connection and fixation of the fixing structure 122 to the main housing assembly 200 through the second threaded fastener 130b can refer to the connection and fixation method of the rotating structure 121 to the screen housing assembly 110 through the first threaded fastener 130a, and will not be described again here.

[0043] The 120-inch rotating shaft can be Figure 3 The strip-shaped rotating shaft shown can also be Figure 4 The hinge pivot shown. Figure 3 As shown, both the rotating structure 121 and the fixed structure 122 of the rotating shaft 120 are strip-shaped. The two opposing ends of the rotating structure 121 and the fixed structure 122 are rotatably inserted together, allowing the rotating structure 121 to rotate relative to the fixed structure 122, forming... Figure 3 The pivot shown is 120. Compared to a hinge pivot, Figure 3 The hinge 120 shown can reduce the contact area between the entire hinge 120 and the screen housing 110 and the main housing 200, which is beneficial to insulate the hinge 120 from the screen housing 110 and the main housing 200 respectively.

[0044] The opposing ends of the rotating structure 121 and the fixed structure 122 can be cylindrical. However, this shape of the rotating structure 121 requires a matching arc-shaped groove within the screen housing assembly 110 to ensure the contact area between the rotating structure 121 and the screen housing assembly 110. While this design ensures the connection stability between the rotating structure 121 and the screen assembly 110, it undoubtedly increases the structural design cost of the screen housing assembly 110. Similarly, this shape of the fixed structure 122 also increases the structural design cost of the main unit housing assembly 200. Therefore, it is possible to... Figure 3 The two ends of the rotating structure 121 and the fixed structure 122, which are opposite to each other, are set as plate-like structures (1211, 1221). This plate-like structure 1211 only requires a planar structure within the screen housing assembly 110 to fit it, ensuring the contact area between the rotating structure 121 and the screen housing assembly 110. Compared to an arc-shaped groove, the planar structure reduces structural design costs while ensuring the connection stability between the rotating shaft 120 and the screen housing assembly 110. Similarly, the plate-like structure 1221 achieves the same effect, which will not be elaborated further here.

[0045] In this embodiment, the stainless steel shaft 120 ensures its rotational performance, thereby guaranteeing frequent rotation between the screen housing assembly 110 and the main housing assembly 200. The first threaded fastener 130a and the second threaded fastener 130b, both made of stainless steel, ensure the secure connection and fixation of the shaft 120 to the screen housing assembly 110 and the main housing assembly 200, respectively.

[0046] The screen housing 110 can be made of aluminum alloy or magnesium alloy, and the main unit housing 200 can also be made of aluminum alloy or magnesium alloy. Preferably, in order to reduce the weight of the ruggedized laptop 10, both the screen assembly 100 and the main unit housing 200 can be made of magnesium alloy.

[0047] In this situation, since the pivot 120, the first threaded fastener 130a, and the second threaded fastener 130b are made of different metal materials than the screen housing assembly 110 and the main unit housing assembly 200, galvanic corrosion is likely to occur when the pivot 120, the first threaded fastener 130a, and the second threaded fastener 130b are connected to the screen housing assembly 110 and the main unit housing assembly 200 respectively under corrosive environments such as salt spray. This corrosion will first occur in the screen housing assembly 110 and the main unit housing assembly 200. Therefore, insulating the pivot 120, the first threaded fastener 130a, and the second threaded fastener 130b from the screen housing assembly 110 and the main unit housing assembly 200 will prevent potential differences between the pivot 120 and the screen housing assembly 110 and the main unit housing assembly 200, between the first threaded fastener 130a and the screen housing assembly 110, and between the second threaded fastener 130b and the main unit housing assembly 200, thereby reducing the degree of corrosion of the screen housing assembly 110 and the main unit housing assembly 200.

[0048] like Figure 3 As shown, a first insulating member 140 can be clamped and fixed between the plate-like structure 1211 and the screen housing assembly 110. The first insulating member 140 isolates the plate-like structure 1211 from the screen housing assembly 110, thus insulating the rotating shaft 120 from the screen housing assembly 110. Similarly, a second insulating member 150 can be clamped and fixed between the plate-like structure 1221 and the main unit housing assembly 200. The second insulating member 150 isolates the plate-like structure 1221 from the main unit housing assembly 200, thus insulating the rotating shaft 120 from the main unit housing assembly 200. The first insulating member 140 can be clamped and fixed by having a through hole, through which a first threaded fastener 130a is sequentially passed to the rotating structure 121 and the through hole on the first insulating member 140, and connected to the threaded hole on the screen housing assembly 110, thereby clamping and fixing the first insulating member 140 between the rotating structure 121 and the screen housing assembly 110. The method by which the second insulating member 150 is clamped and fixed between the fixing structure 122 and the main housing assembly 200 can be the same as the method by which the first insulating member 140 is clamped and fixed, and will not be described again here.

[0049] In some embodiments, the surfaces of the rotating shaft 120, i.e. the rotating structure 121 and the fixed structure 122, can be insulated, for example by spraying insulating powder or spraying insulating paint, so that the rotating structure 121 and the fixed structure 122 have an insulating powder layer or an insulating paint layer, thereby making the rotating shaft 120 insulated from the screen housing 110 and the main housing 200.

[0050] Optionally, a liquid insulating adhesive, such as liquid silicone rubber, can be applied to the surface of the first threaded fastener 130a. The solidified liquid insulating adhesive can isolate the first threaded fastener 130a from the screen housing assembly 110, thus insulating the first threaded fastener 130a from the screen housing assembly 110. Furthermore, the solidified liquid insulating adhesive can effectively prevent salt spray, acid spray, and other mist-like corrosive particles from entering the screen housing assembly 110 through the through-holes and corroding the inner wall of the screen housing assembly 110. The insulation method between the second threaded fastener 130b and the main unit housing assembly 200 is similar to that between the threaded fastener 130 and the screen housing assembly 110, and will not be described further here.

[0051] In the ruggedized laptop 10 provided in this application embodiment, the rotating structure 121 and the fixed structure 122 of the hinge 120 are respectively connected to the screen housing assembly 110 and the main body housing assembly 200 through the first threaded fastener 130a and the second threaded fastener 130b, so that the screen housing assembly 110 can rotate relative to the main body housing assembly 200 through the rotating structure 121 and the fixed structure 122 that are rotatably connected. The stainless steel hinge 120 has good rotational performance. The stainless steel first threaded fastener 130a and second threaded fastener 130b make the connection between the hinge 120 and the screen housing assembly 110 and the main housing assembly 200 more stable. When the screen housing assembly 110 and the main housing assembly 200 are made of different metals than the hinge 120, the first threaded fastener 130a and the second threaded fastener 130b, the hinge 120, the first threaded fastener 130a and the second threaded fastener 130b are all insulated from the screen housing assembly 110 and the main housing assembly 200. This can prevent galvanic corrosion of the hinge 120, the first threaded fastener 130a and the second threaded fastener 130b with the screen housing assembly 110 and the main housing assembly 200 in corrosive environments, reduce the degree of corrosion of the screen housing assembly 110 and the main housing assembly 200, and improve the overall corrosion resistance of the ruggedized laptop 10.

[0052] like Figure 3 As shown, the screen housing assembly 110 includes a first housing 111 and a second housing 112. The second housing 112 is fastened to the first housing 111, and a mounting cavity (not shown in the figure) is formed between the first housing 111 and the second housing 112. The first housing 111 has a window 11111, and a screen unit 113 is disposed in the mounting cavity. The screen unit 113 covers the inside of the window 1111, so that the screen unit 113 can be exposed through the window 1111.

[0053] The screen unit 113 has a metal frame 1131 at its edge. Optionally, the metal frame 1131 can be threadedly fixed to the first housing 111 to secure the screen unit 113 to the first housing 111. In this case, as... Figure 3 and Figure 5As shown, an annular conductive element 114 is sandwiched between the inner wall of the metal frame 1131 and the edge of the window 1111. The conductive element 114 fills the gap between the metal frame 1131 and the first housing 111, so that the first housing 111, the second housing 112, the screen unit 113 and the metal frame 1131 can form a metal enclosed space, effectively preventing electromagnetic waves from radiating out from the gap between the metal frame 1131 and the first housing 111 when the screen unit 113 is working.

[0054] The conductive element 114 can be conductive silicone. Alternatively, the conductive element 114 can also be a waterproof conductive structure, such as conductive foam, to prevent liquids carrying corrosive particles from entering the screen housing assembly 110 through the gap between the metal frame 1131 and the first housing 111 and corroding the internal components. When the conductive element 114 is a waterproof conductive structure, since the liquid absorbed by the conductive element 114 carries corrosive particles, this will corrode the metal frame 1131. Therefore, it can be protected as follows: Figure 3 and Figure 5 As shown, an annular first seal 115 is sandwiched between the inner wall of the screen unit 113 and the edge of the window 1111. The first seal 115 absorbs liquid carrying corrosive particles. The first seal 115 can be waterproof foam, which prevents liquid carrying corrosive particles from passing through the gap between the screen unit 113 and the inner wall of the window 1111 edge, further reducing the entry of liquid carrying corrosive particles into the screen housing assembly 110, thereby effectively slowing down the corrosion rate of the metal frame 1131 and the internal components of the screen housing assembly 110.

[0055] Furthermore, such as Figure 3 As shown, a fixed annular second sealing member 116 is sandwiched between the first housing 111 and the second housing 112. This second sealing member 116 prevents liquid carrying corrosive particles from entering the screen housing assembly 110 through the gap between the first housing 111 and the second housing 112, further slowing down the corrosion rate of the internal components of the screen housing assembly 110. Optionally, it can be as follows... Figure 5 As shown, a mounting groove 1112 is provided on the first housing 111 to fix the second seal 116, making the assembly of the second seal 116 more convenient. The second seal 116 can be conductive foam or conductive silicone, etc., which not only prevents liquids carrying corrosive particles from passing through the gap between the first housing 111 and the second housing 112, but also prevents electromagnetic waves from radiating out from the gap between the first housing 111 and the second housing 112.

[0056] Please continue reading. Figure 3 and combined Figure 6 , Figure 6A schematic diagram of the screen housing assembly is shown. As shown, two through holes 1113 for the two rotating shafts 120 to extend out and two outlet holes 1114 for different cables to pass through are formed between the first housing 111 and the second housing 112. Applying liquid insulating adhesive, such as liquid silicone rubber, to the gaps between the rotating shafts 120 and the through holes 1113 and between the cables and the outlet holes 1114 can prevent corrosive particles such as salt spray and acid spray from entering the screen housing assembly 110 through the gaps. Similarly, applying a ring of liquid insulating adhesive to the edge of the screen unit 113 to form an insulating ring 1132 can achieve the same effect, which will not be described in detail here.

[0057] Figure 7 An exploded view of the host housing assembly provided in an embodiment of this application is shown, as follows: Figure 7 As shown, a partition 210 is provided inside the main unit housing 200. The partition 210 divides the internal space of the main unit housing 200 into an isolated mounting cavity 220 and a heat dissipation cavity 230.

[0058] Normally, such as Figure 7 As shown, the main unit housing assembly 200 may include a main unit housing 201 and a bottom cover 202. The bottom cover 202 is placed on the main unit housing 201 and fixedly connected to it. The internal space of the main unit housing 201 is divided by a partition 210 to form a mounting cavity 220 and a heat dissipation cavity 230. In some embodiments, in order to prevent mist-like corrosive particles from entering the mounting cavity 220, a sealing ring 203 is sandwiched between the partition 210, the main unit housing 201, and the bottom cover 202. The sealing ring 203 can prevent mist-like corrosive particles from passing through the gaps between the main unit housing 201 and the bottom cover 202, and between the partition 210 and the bottom cover 202, effectively protecting the devices inside the mounting cavity 220.

[0059] The mounting cavity 220 houses a motherboard 221, and the heat dissipation cavity 230 houses a heat sink 231. A heat-conducting component 232 connects the heat sink 231 and the motherboard 221, transferring heat from the motherboard 221 to the heat sink 231. Optionally, to ensure the thermal conductivity of the heat sink 231 and the heat-conducting component 232 and achieve good heat dissipation, the heat sink 231 and the heat-conducting component 232 can be made of copper or aluminum.

[0060] like Figure 7As shown, the heat-conducting component 232 includes a heat-dissipating patch 2321 and a heat-conducting pipe 2322. The heat-dissipating patch 2321 is fixedly connected to and adheres to the motherboard 221, and is used to conduct heat generated by the motherboard 221 to the heat-conducting pipe 2322. The heat-conducting pipe 2322 is connected to the heat sink 231, and is used to conduct heat generated by the motherboard 221 to the heat sink 231. In one embodiment, the heat-conducting pipe 2322 is sealed through a partition 210 and connected to the heat sink 231. Specifically, a U-shaped notch and a detachable fastener 211 can be provided on the partition 210, and the heat-conducting pipe 2322 passes through the through hole formed by the notch on the partition 210 and the notch on the fastener 211, connecting to the heat sink 231 in the heat dissipation cavity 230. Furthermore, liquid insulating adhesive can be applied to the gap between the through hole and the heat pipe 2322 to achieve a sealed isolation between the mounting cavity 220 and the heat dissipation cavity 230, effectively preventing salt spray, acid spray and other mist-like corrosive particles from entering the mounting cavity 220 and corroding the motherboard 221.

[0061] To dissipate the heat generated by the motherboard 221 to the outside of the ruggedized laptop 10, the main unit casing 200 has ventilation holes 212 at opposite ends of the heat dissipation cavity 230. A fan 233 is installed inside the heat dissipation cavity 230, and a heat sink 231 is installed in the gap between the fan 233 and the ventilation holes 212. The fan 233 is used to draw external air from the heat sink. Figure 7 The air intake 213 shown draws air into the heat dissipation cavity 230. After the external air absorbs the heat from the heat sink 231, the fan 233 also discharges the heat-absorbing air to the outside of the ruggedized laptop 10 through the ventilation hole 212.

[0062] When the heat sink 231 and heat conductor 232 are made of copper, and the main unit housing 200 and partition 210 are made of aluminum alloy or magnesium alloy, or when the heat sink 231 and heat conductor 232 are made of aluminum, and the main unit housing 200 and partition 210 are made of magnesium alloy, contact between the heat sink 231 and heat conductor 232 and the main unit housing 200 and partition 210 in corrosive environments such as salt spray and acid spray will accelerate the corrosion of the main unit housing 200. Therefore, to avoid the above situation, the heat sink 231 is insulated from the inner wall of the heat dissipation cavity 230, i.e., the main unit housing 200, and the heat conductor 232 is insulated from the partition 210, so that no potential difference is generated between the heat sink 231 and the inner wall of the main unit housing 200, and between the heat conductor 232 and the partition 210, thereby ensuring the corrosion resistance of the main unit housing 200 and partition 210.

[0063] Specifically, insulating powder or insulating varnish can be sprayed onto the portion of the heat pipe 2322 that penetrates the partition 210 to insulate the heat pipe 2322 from the partition 210. Furthermore, insulating powder or insulating varnish can also be sprayed onto the portion of the heat pipe 2322 located within the heat dissipation cavity 230 to prevent corrosion of the heat pipe 2322 by liquids entering the heat dissipation cavity 230. Similarly, the same method can be used to insulate the heat sink 231, which will not be elaborated further here.

[0064] Optionally, heat dissipation fins 2311 can be arranged side-by-side on the heat sink 231 to increase the contact area between the heat sink 231 and the external air, thereby dissipating heat from the heat sink 231 more quickly and improving the heat dissipation effect on the motherboard 221. Furthermore, the distance between adjacent heat dissipation fins 2311 can be 1-2 mm to maximize the contact area between the heat sink 231 and the external air. However, because the gaps between the heat dissipation fins 2311 are small, deviations in the spraying angle may result in the gaps between the heat dissipation fins 2311 not being coated when applying insulating varnish, thus affecting the corrosion resistance of the heat sink 231. In this case, insulating powder can be sprayed onto the heat dissipation fins 2311. Through electrostatic adsorption, the gaps between the heat dissipation fins 2311 can also be covered with insulating powder, resulting in an insulating powder layer on the surface of the heat dissipation fins 2311, achieving insulation from the motherboard casing 200.

[0065] like Figure 2 and Figure 7 As shown, in order to prevent mist-like corrosive particles from entering the mounting cavity 220 from all the side IO ports and eroding the components inside the mounting cavity 220, a rotatable IO window blade 240 is provided at the IO port of the main housing assembly 200, and a sealing ring 241 is sandwiched between the main housing assembly 200 and the IO window blade 240. The sealing ring 241 can effectively prevent external liquid from entering the mounting cavity 220 from the IO window blade 240.
