Description

Technical Field

[0001] The present application relates to the technical field of server structure design, and specifically to a chassis, an optimization method, an apparatus, an electronic device, a storage medium, and a program product. Background Art

[0002] In related technologies, safety regulations refer to product safety requirements in product certification, which are implemented throughout the entire product lifecycle, from design to sales and end-user use. This product safety compliance encompasses not only general product safety but also requirements for electromagnetic compatibility and radiation, energy conservation, and environmental protection. It is a product safety responsibility and activity that runs throughout the product lifecycle.

[0003] Safety regulations require that the opening size of the 5° projection area of ​​the ignition source (potential ignition source) inside the chassis must be no larger than 3mm; therefore, during the product design process, the opening size in the area projected by the ignition source should be changed to 3mm.

[0004] However, the 3mm opening cannot guarantee the heat dissipation requirements of the server, affecting the reliability of the server operation. Summary of the Invention

[0005] In view of this, the present application provides a chassis, an optimization method, an apparatus, an electronic device, a storage medium and a program product to solve or improve the problem of poor heat dissipation of the server and improve the reliability of service operation.

[0006] In a first aspect, the present application provides a chassis having components disposed therein, the chassis comprising:

[0007] The bottom plate, the components are oriented toward the bottom plate to form an ignition source flame region having a preset expansion angle;

[0008] A side window is connected to the bottom plate, the side window is provided with a first heat dissipation hole portion, the first heat dissipation hole portion is located in the ignition source flame area, and the opening size of the first heat dissipation hole portion is greater than a first set value;

[0009] The outer side of the side window is connected to a first extended edge, and the first extended edge is suitable for receiving the portion of the ignition source flame area that passes through the first heat dissipation hole portion.

[0010] In this embodiment, multiple components are arranged within the chassis. During operation, these components are prone to failure and the risk of spontaneous combustion. Upon spontaneous combustion of a component, an ignition source flame region with a preset expansion angle is formed. This ignition source flame region originates from the component and expands both horizontally and vertically to form a conical ignition source flame region. Safety regulations limit the size of the openings in the chassis within this region to 3 mm. This prevents molten material from spontaneously combusting components from ejecting out of the chassis through the first heat dissipation holes, potentially causing fire and other hazards.

[0011] However, the size of the opening is 3mm, which is not conducive to the heat dissipation of the chassis, and can easily lead to excessively high temperatures inside the chassis, reducing the operating efficiency of the components inside the chassis. Therefore, a first extended edge is provided on the outside of the side window. Along the height direction of the chassis, the first extended edge is provided below the first heat dissipation hole portion. The first extended edge receives the portion where the ignition source flame area passes through the first heat dissipation hole portion, that is, it can receive the molten material ejected from the first heat dissipation hole portion after the components spontaneously combust. Therefore, when the opening size of the first heat dissipation hole portion is greater than 3mm and the first extended edge is provided on the side window, the heat dissipation effect of the chassis and the operating reliability of the components inside the chassis can be improved while complying with safety regulations.

[0012] In a second aspect, the present application provides a chassis optimization method, wherein the chassis includes a bottom plate and a side window connected thereto, and components are provided in the chassis. The components have a direction toward the bottom plate, forming an ignition source flame area with a preset expansion angle, and are applied to a controller. The structural optimization method includes:

[0013] Obtain the flame area of ​​the ignition source;

[0014] Obtaining the size of an opening on a first heat dissipation hole portion, wherein the first heat dissipation hole portion is provided on the side window and is located within the ignition source flame region;

[0015] Determining whether the size of the opening on the first heat dissipation hole portion is greater than a first set value;

[0016] If so, a first extended edge is provided in a corresponding area outside the side window, receiving the portion of the ignition source flame area that passes through the first heat dissipation hole portion.

[0017] In a third aspect, the present application provides an optimization device, comprising:

[0018] an acquisition module, configured to acquire the ignition source flame region and to acquire the size of an opening on a first heat dissipation hole portion, wherein the first heat dissipation hole portion is located on the side window and within the ignition source flame region;

[0019] a judgment module, configured to judge whether the size of the opening on the first heat dissipation hole portion is greater than a first set value;

[0020] The adjustment module is used to set a first extended edge of the portion of the ignition source flame area that passes through the first heat dissipation hole portion in a corresponding area outside the side window.

[0021] In a fourth aspect, the present application provides an electronic device comprising: a memory and a processor, the memory and the processor being communicatively connected to each other, the memory storing computer instructions, and the processor executing the chassis optimization method by executing the computer instructions.

[0022] In a fifth aspect, the present application provides a computer-readable storage medium having computer instructions stored thereon, the computer instructions being used to enable a computer to execute a chassis optimization method.

[0023] In a sixth aspect, the present application provides a computer program product, comprising computer instructions, which are used to enable a computer to execute a chassis optimization method. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] To make the purpose, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of this application.

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections; they can refer to direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0046] In related technologies, safety regulations refer to product safety requirements in product certification, which are implemented throughout the entire product lifecycle, from design to sales and end-user use. This product safety compliance encompasses not only general product safety but also requirements for electromagnetic compatibility and radiation, energy conservation, and environmental protection. It is a product safety responsibility and activity that runs throughout the product lifecycle.

[0047] Safety regulations require that the opening size of the 5° projection area of ​​the PIS (potential ignition source) inside the chassis must be no larger than 3mm; therefore, during the product design process, the opening size in the area projected by the ignition source should be reduced to 3mm.

[0048] However, a 3mm opening cannot guarantee the heat dissipation requirements of the server, affecting the reliability of the server operation. To this end, the present application provides a chassis, a structural optimization method, an apparatus, a computer, a medium, and a program product to solve or improve the problem of poor server heat dissipation and improve the reliability of service operation.

[0049] The following combination Figures 1 to 14 , describing the embodiments of the present application.

[0050] According to an embodiment of the present application, on the one hand, Figure 1 As shown, a chassis is provided with components 6 inside. The chassis includes: a bottom plate 1 and a side window 2. The bottom plate 1 and the side window 2 are arranged vertically. The bottom plate 1 is arranged in the horizontal direction, and the side window 2 is arranged in the vertical direction.

[0051] Component 6 in this application mainly refers to a component that is prone to spontaneous combustion, and component 6 is a type of PIS.

[0052] In safety design, chassis fire protection is a key focus. Based on regulatory requirements, flame models are categorized as resistive PIS (potential ignition source) and arc PIS. A resistive PIS is located in the PS2 (interface on the computer system, primarily used to connect input devices such as keyboards and mice) or PS3 (high-power power supply) circuits. The power measured after 30 seconds of normal operation is greater than 15W, or within 30 seconds of a single fault, the power measured is greater than 100W, or after 30 seconds of a single fault, the power measured is greater than 15W. An arc PIS is located in a potentially disconnected connection within the PS2 or PS3 circuits, such as a switch, terminal, or copper foil on a printed circuit board. After 3 seconds, the open-circuit voltage measured is greater than 50Vpeak (peak value), and the product of the rms (equivalent current) and peak voltage is greater than 15. Therefore, in circuit design, a PIS can be a point, component, or printed circuit board trace. When the actual product certification laboratory determines, the (personal identification code), components 6 and PCB (printed circuit board) traces close to the electronic product will be defined as PIS.

[0053] Specifically, such as Figure 1 As shown, component 6 serves as a potential ignition source. Component 6 faces toward the base plate 1, forming an ignition source flame area 11 with a preset expansion angle. The ignition source flame area 11 takes component 6 as the starting point and spreads outward toward the base plate 1 to form a conical area. The angle between the generatrix of the conical area and its axis is α, that is, the angle between the boundary of the ignition source flame area 11 and the vertical direction, wherein the preset expansion angle α is equal to 5°; starting from component 6, the maximum length of the conical area expanded in the horizontal direction is 15 mm.

[0054] Specifically, such as Figure 1 、 Figure 2 and Figure 8 As shown, the side window 2 is connected to the base plate 1 and is provided with a first heat dissipation hole section 3. The first heat dissipation hole section 3 is located within the ignition source flame region 11. The opening size of the first heat dissipation hole section 3 is greater than a first set value, wherein the first set value is 3 mm. The first heat dissipation hole section 3 includes a plurality of first heat dissipation holes arranged in an array on the first heat dissipation hole section 3. The array arrangement can be a matrix arrangement or a circular array arrangement. The first heat dissipation holes can also be regular shapes such as circular, elliptical, square, or other special shapes. Specifically, the first heat dissipation holes are circular, and the diameter of the first heat dissipation holes is greater than or equal to 5 mm.

[0055] It should be noted that the side window 2 can be the front window or the rear window of the chassis or a side panel between the front window and the rear window.

[0056] Specifically, such as Figure 1 、 Figure 2 and Figure 8 As shown, the outer side of the side window 2 is connected to a first extended edge 4, and the first extended edge 4 is suitable for receiving the part of the ignition source flame area 11 that passes through the first heat dissipation hole portion 3, wherein the first extended edge 4 is a plate-like structure, and the first extended edge 4 is fixedly connected to the side window 2 and arranged vertically. The connection method can be an one-piece molding connection, a welding connection, or a bolt connection.

[0057] In some embodiments not shown, the first extended edge 4 may be arranged at an angle to the side window 2 to ensure that the length of the first extended edge 4 in the direction perpendicular to the side window 2 can accommodate the portion of the ignition source flame area 11 passing through the first heat dissipation hole portion 3 .

[0058] In some embodiments, as Figure 1 、 Figure 2 and Figure 8 As shown, multiple components 6 are arranged within the chassis. During operation, components 6 are prone to failure and the risk of spontaneous combustion. After component 6 spontaneously ignites, molten material is ejected, forming an ignition source flame region 11 with a preset expansion angle. Ignition source flame region 11 starts at component 6 and expands horizontally and vertically to form a conical ignition source flame region 11. The size of the openings in the chassis within this region is limited by safety regulations to 3mm. This prevents molten material generated by the spontaneous combustion of component 6 from ejecting out of the chassis through the first heat dissipation hole portion 3 and causing fire hazards.

[0059] However, the size of the opening is 3mm, which is not conducive to heat dissipation from the chassis, and can easily lead to excessive internal temperature of the chassis, reducing the operating efficiency of the components inside the chassis. Therefore, a first extended edge 4 is provided on the outside of the side window 2. Along the height direction of the chassis, the first extended edge 4 is provided below the first heat dissipation hole portion 3. The first extended edge 4 receives the portion where the ignition source flame region 11 passes through the first heat dissipation hole portion 3, that is, it can receive the molten material ejected from the first heat dissipation hole portion 3 after the component 6 spontaneously combusts. Therefore, when the opening size of the first heat dissipation hole portion 3 is greater than 3mm, and the first extended edge 4 is provided on the side window 2, the heat dissipation effect of the chassis and the operating reliability of the components inside the chassis can be improved while complying with safety regulations.

[0060] In one embodiment, Figure 3 As shown, the side window 2 has a recessed portion 5. Specifically, the recessed direction of the recessed portion 5 is perpendicular to the side window 2 toward the inside of the chassis. The inside of the recessed portion 5 forms an opening surface 7 perpendicular to the bottom plate 1 and a bottom surface 8 parallel to the bottom plate 1, and the second heat dissipation hole portion is opened on the opening surface 7.

[0061] In an embodiment not shown, the top surface of the recessed portion 5 corresponding to the bottom surface 8 can be parallel to the bottom surface 8 or non-parallel to the bottom surface 8. When the top surface is non-parallel to the bottom surface 8, the top surface extends upward away from the side window 2, and the opening of the recessed portion 5 is a bell-shaped opening, which facilitates heat dissipation by the second heat dissipation hole portion; when the top surface extends downward away from the side window 2, the opening of the recessed portion 5 is a constricted opening, which can improve the dust-proof effect of the second heat dissipation hole portion.

[0062] Specifically, such as Figure 3 As shown, the recessed portion 5 is a groove, and the groove and the side window 2 are integrally stamped.

[0063] Specifically, the recessed portion 5 is located within the ignition source flame region 11. A second heat dissipation hole portion is provided on the surface of the recessed portion 5 perpendicular to the bottom plate 1. Specifically, the second heat dissipation hole portion is provided on the opening surface 7. The opening size of the second heat dissipation hole portion is greater than a first set value, wherein the first set value is 3 mm. The length of the bottom surface 8 of the recessed portion 5 perpendicular to the side window 2 is no less than a target length C; where C = N × tanα, where N is the dimension of the recessed portion 5 along the height direction of the chassis and α is the predetermined expansion angle.

[0064] In some embodiments, as Figure 3 As shown, N is the distance between the component 6 and the bottom surface 8 of the recessed portion 5 along the height direction of the chassis. At this time, the component 6 is located at the highest point on the surface perpendicular to the bottom plate 1. The maximum length of the bottom surface 8 of the recessed portion 5 can be obtained by trigonometric calculation.

[0065] In some embodiments, the component 6 is located on a surface perpendicular to the bottom plate 1, but is not the highest point along the height direction of the chassis. N is the distance between the component 6 and the bottom surface 8 of the recessed portion 5 along the height direction of the chassis. The target length C calculated by trigonometric function is the shortest length of the portion that receives the ignition source flame area 11 and passes through the second heat dissipation hole portion.

[0066] In some embodiments, as Figure 3 As shown, in the case where there is a recessed portion 5 on the side window 2, and a second heat dissipation hole portion is provided on the surface of the recessed portion 5 along the direction perpendicular to the bottom plate 1, in order to ensure that the size of the second heat dissipation hole portion can be greater than 3 mm and improve the heat dissipation effect of the chassis, the length of the bottom surface 8 of the recessed portion 5 along the direction perpendicular to the side window 2 is not less than the target length C. When the component 6 is located on the surface of the recessed portion 5 along the direction perpendicular to the bottom plate 1, the target length C is the limit length of the bottom surface 8 of the recessed portion 5. Therefore, when the length of the bottom surface 8 of the recessed portion 5 is the target length C, the bottom surface 8 of the recessed portion 5 can receive the part of the ignition source flame area 11 that passes through the second heat dissipation hole portion, so that the size of the second heat dissipation hole portion can be greater than the first set value, that is, the size of the second heat dissipation hole portion can be greater than 3 mm.

[0067] Specifically, the second heat dissipation hole portion includes a plurality of second heat dissipation holes, which can be regular shapes such as circular, elliptical, square, or other special shapes. Specifically, the second heat dissipation holes are circular, and the diameter of the second heat dissipation holes is greater than or equal to 5 mm.

[0068] In one embodiment, Figure 4 and Figure 5 As shown, a third heat dissipation hole portion is provided on the bottom surface 8 of the recessed portion 5. The size of the opening on the third heat dissipation hole portion is not greater than the first set value, that is, the size of the third heat dissipation hole portion is not greater than 3 mm. When the components 6 inside the chassis spontaneously combust, the resulting molten material will not be ejected from the second heat dissipation hole portion to the bottom surface 8 of the recessed portion 5, but will be ejected into the chassis from the opened third heat dissipation hole portion. Therefore, providing the third heat dissipation hole portion on the bottom surface 8 of the recessed portion 5 can further improve the heat dissipation effect of the chassis.

[0069] In some embodiments, the third heat dissipation hole portion includes a plurality of third heat dissipation holes, which can be regular shapes such as circular, elliptical, square, or other irregular shapes. Specifically, the third heat dissipation hole is circular, and the diameter of the second heat dissipation hole is not greater than 3 mm.

[0070] In one embodiment, Figure 1 As shown, the length of the first extended side 4 extended in a direction perpendicular to the side window 2 is the target length A, satisfying: A≥L×tanα; where L is the distance between the first extended side 4 and the component 6 along the height direction of the chassis, and α is the preset expansion angle.

[0071] It should be noted that the target length A is the length of the first extended side 4 projected onto a plane perpendicular to the side window 2 . Therefore, the first extended side 4 may not be perpendicular to the side window 2 .

[0072] Specifically, such as Figure 7 As shown, the chassis height can be categorized as 1U, 2U, 3U, 4U, 5U, 6U, 7U, 8U, 9U, and 10U, where 1U = 1.75 inches = 44.45mm. Therefore, when L = 44.45mm, A = 44.45mm × tan5° = 44.45mm × 0.0875 = 3.889375mm. Therefore, when the chassis height is 1U, the length of the first extended side 4 is greater than or equal to 3.889375mm, and it is located at the bottom of the corresponding side window 2 of the chassis. The size of the first heat dissipation hole in the side window 2 is greater than or equal to 5mm. The degree of α is 5°.

[0073] Specifically, such as Figure 7As shown, 2U = 13.5 inches = 88.9mm. Therefore, when L = 88.9mm, A = 88.9mm × tan5° = 88.9mm × 0.0875 = 7.77875mm. Therefore, when the height of the chassis is 2U, the length of the first extended side 4 is greater than or equal to 7.77875mm and is located at the bottom of the corresponding side window 2 of the chassis. The size of the first heat dissipation hole in the side window 2 is greater than or equal to 5mm. The degree of α is 5°.

[0074] In a specific application scenario, such as Figure 1 、 Figure 2 and Figure 8 As shown, a first heat dissipation hole portion 3 is provided on the side window 2, the diameter of the first heat dissipation hole portion 3 is greater than or equal to 5 mm, the first extended edge 4 is vertically provided on the side window 2 and is located below the first heat dissipation hole portion 3, and the component 6 is located at the upper edge of the first heat dissipation hole portion 3, and the distance between the first extended edge 4 and the component 6 along the height direction of the chassis is 2U, that is, L = 88.9 mm, α is a preset expansion angle of 5°, and according to A≥L×tanα, the minimum value of A is 7.77875 mm.

[0075] In a specific application, according to the ignition source flame area 11 and the distance between the first extended side 4 and the component 6 along the height direction of the chassis, the target length A corresponding to the components 6 of different heights can be calculated by trigonometric functions.

[0076] Specifically, according to the above calculation method, the length L of the first extended side 4 corresponding to the height of the chassis of 3U, 4U, 5U, 6U, 7U, 8U, 9U, 10U, etc. can be calculated respectively, as shown in Table 1:

[0077] Table 1

[0078]

[0079] It should be noted that if Figure 1 and Figure 2 As shown, component 6 serves as a potential ignition source. The maximum horizontal extension of the conical area starting from component 6 is 15 mm. Therefore, when first extended side 4 is perpendicular to side window 2, the maximum horizontal length of first extended side 4 is 15 mm, with the direction perpendicular to side window 2 being parallel to the horizontal direction. Therefore, the maximum target length A is 15 mm.

[0080] In one embodiment, Figure 4 and Figure 5As shown, the length of the bottom surface 8 of the recessed portion 5 in a direction perpendicular to the side window 2 is less than a preset length D. A second extended edge 9 is connected to the outer side of the side window 2. Specifically, the second extended edge 9 is a plate-like structure. The second extended edge 9 can be arranged perpendicular to the side window 2 or not. When the second extended edge 9 is not perpendicular to the side window 2, the length of the second extended edge 9 refers to the length of its projection on the plane perpendicular to the side window 2. When the second extended edge 9 is perpendicular to the side window 2, the length of the second extended edge 9 refers to the length in a direction perpendicular to the side window 2. The second extended edge 9 is fixedly connected to the side window 2, and the connection method can be an integral molding connection, a welding connection, or a bolt connection.

[0081] Along the height of the chassis, such as Figure 4 and Figure 5 As shown, the second extended side 9 is located below the recessed portion 5 and is arranged in the ignition source flame area 11; along the direction perpendicular to the side window 2, the sum of the length of the second extended side 9 and the length of the bottom surface 8 of the recessed portion 5 is not less than the preset length D, satisfying: D=S×tanα; wherein S is the distance between the second extended side 9 and the component 6 along the height direction of the chassis, and α is the preset expansion angle.

[0082] like Figure 4 and Figure 5 As shown, the length of the bottom surface 8 of the recessed portion 5 perpendicular to the side window 2 is less than a predetermined length D, resulting in the bottom surface 8 of the recessed portion 5 being unable to receive the entire portion of the ignition source flame region 11 extending through the second heat dissipation aperture. Therefore, the size of the second heat dissipation aperture provided on the surface of the recessed portion 5 perpendicular to the bottom plate 1 is limited to 3 mm in accordance with safety regulations, resulting in poor heat dissipation in the chassis. To further optimize the chassis, a second extended edge 9 is provided on the side window 2. The second extended edge 9 is arranged perpendicular to the side window 2 and located below the second heat dissipation aperture. The sum of the length of the second extended edge 9 and the length of the bottom surface 8 of the recessed portion 5 is no less than the predetermined length D. This allows the second extended edge 9 and the bottom surface 8 of the recessed portion 5 to collectively receive the entire portion of the ignition source flame region 11 extending through the second heat dissipation aperture, that is, to receive the molten material ejected from the second heat dissipation aperture. By providing the second extended edge 9, the chassis is optimized, with the size of the second heat dissipation aperture being greater than or equal to 5 mm, improving the chassis' heat dissipation and complying with safety regulations.

[0083] In some embodiments, as Figure 4 and Figure 5As shown, when the space required inside the chassis is limited, the distance that the recessed portion 5 is recessed toward the inside of the chassis is limited. At this time, a second extended edge 9 can be connected to the side window 2 corresponding to the recessed portion 5. The second extended edge 9 is located below the recessed portion 5, making full use of the space outside the chassis so that the sum of the length of the second extended edge 9 and the length of the bottom surface 8 of the recessed portion 5 can meet the condition of being no less than the preset length D.

[0084] In some embodiments, when the external space of the chassis is limited, the length of the second extended side 9 is restricted. At this time, it can be recessed toward the inside of the chassis to form a recessed portion 5, making full use of the space inside the chassis, so that the sum of the length of the second extended side 9 and the length of the bottom surface 8 of the recessed portion 5 can meet the condition of not less than the preset length D.

[0085] In some specific application scenarios, such as Figure 4 and Figure 5 As shown, the sum of the length of the second extended side 9 and the length of the bottom surface 8 of the recessed portion 5 is equal to the preset length D. Specifically, the height of the chassis is 1U, where 1U = 1.75 inches = 44.45mm. Therefore, when L = 44.45mm, A ≥ 44.45mm × tan5° = 44.45mm × 0.0875 = 3.889375mm. If a heat dissipation hole of 5mm or larger is designed for the side window 2 of a chassis with a height between 1U and 2U, the side window 2 of the chassis with a height between 1U and 2U can be retracted perpendicularly and toward the interior of the chassis by a target length C to form the recessed portion 5. The length of the bottom surface 8 of the recessed portion 5 is the target length C, where C = N × tanα, where N is the height of 1U, that is, 44.45mm, and α is 5°. The calculated target length C is 3.889375mm.

[0086] In some embodiments, as Figure 4 and Figure 5As shown, if a heat dissipation hole larger than 5mm is designed on the side window 2 of a chassis with a height between 1U and 2U, the side window 2 of the chassis with a height between 1U and 2U can be retracted in a direction perpendicular to the side window 2 and toward the inside of the chassis by a target length C to form a recessed portion 5. The length of the bottom surface 8 of the recessed portion 5 is the target length C. However, the calculated target length C is less than 3.889375mm. In this case, a second extended edge 9 needs to be provided on the side window 2. The second extended edge 9 is located below the recessed portion 5 along the height direction of the chassis. The long side 9 makes up for the defect of insufficient length of the bottom surface 8 of the recessed portion 5. The second extended side 9 extends in the direction perpendicular to the side window 2. When the sum of the lengths of the second extended side 9 and the bottom surface 8 of the recessed portion 5 in the direction perpendicular to the side window 2 meets the condition of being greater than or equal to the preset length D, the second extended side 9 and the bottom surface 8 of the recessed portion 5 can jointly undertake the part of the ignition source flame area 11 that passes through the second heat dissipation hole portion. Therefore, the size of the second heat dissipation hole portion is greater than 3 mm, which meets the requirements of safety regulations and further improves the heat dissipation effect of the server and the reliability of service operation.

[0087] In some embodiments, the preset length D=S×tanα, where S is the distance between the second extended side 9 and the component 6 along the height direction of the chassis, and α is 5°. Figure 5 As shown, taking the second extended edge 9 being set at the bottom of the side window 2 as an example, at this time, S is 2U, 2U=88.9mm, so when S=88.9mm, D=88.9mm×tan5°=88.9mm×0.0875=7.77875mm, therefore, the length of the second extended edge 9 is equal to 7.77875mm minus the length of the bottom surface 8 of the recessed portion 5.

[0088] Different from the above embodiment, Figure 4 As shown, taking the second extended side 9 being set at the height between the bottom plate 1 and 1U as an example, S is the distance between the second extended side 9 and the component 6 along the height direction of the chassis.

[0089] In some embodiments, if a heat dissipation hole of 5 mm or more is designed on the side window 2 of a chassis with a height between 0.5U and 1U, the side window 2 of the chassis with a height between 0.5U and 1U can be retracted by a target length C in a direction perpendicular to it and toward the inside of the chassis to form a recessed portion 5. The length of the bottom surface 8 of the recessed portion 5 is the target length C, where C = N × tanα, N is the height of 0.5U, that is, 22.225 mm, α is 5°, and the calculated target length C is 1.9446875 mm.

[0090] In specific applications, such as Figure 4 、 Figure 5 and Figure 8As shown, a recessed portion 5 is provided on the side window 2, and a second heat dissipation hole portion is provided on the opening surface 7 of the recessed portion 5. The length of the bottom surface 8 of the recessed portion 5 along the direction perpendicular to the side window 2 is 2 mm. The vertical distance between the component 6 and the bottom surface 8 of the recessed portion 5 is 1U, that is, 44.45 mm. According to the target length C = N × tan5° = 3.889375 mm. However, the bottom surface 8 of the recessed portion 5 is only 2 mm long. Therefore, a second extended edge 9 is required below the recessed portion 5. The second extended edge 9 is arranged perpendicular to the side window 2, and the distance between the second extended edge 9 and the component 6 along the height direction of the chassis is 2U, that is, 88.9 mm. Therefore, when S = 88.9 mm, D = 88.9 mm × tan5° = 88.9 mm × 0.0875 = 7.77875 mm. Therefore, the length of the second extended edge 9 = 7.77875 mm - 2 mm = 5.77875 mm.

[0091] In one embodiment, Figure 8 As shown, the first extended edge 4 and the recessed portion 5 are staggered along the third direction, wherein the third direction is parallel to the side window 2 , and wherein the third direction is the same as the fourth direction.

[0092] In some embodiments, as Figure 8 As shown, on the same side window 2, the first extended edge 4 and the recessed portion 5 can be designed at the same time according to different requirements. And on the same side window 2, the first extended edge 4, the recessed portion 5 and the second extended edge 9 can be designed at the same time according to different requirements.

[0093] In some embodiments, the first extended edge 4 and the recessed portion 5 are not provided on the same side window 2 , but may be adjacent side windows 2 or opposite side windows 2 .

[0094] In one embodiment, Figure 6 and Figure 8 As shown, the side window 2 is provided with a fourth heat dissipation hole portion 10, the fourth heat dissipation hole portion 10 is located in the ignition source flame area 11, the thickness of the fourth heat dissipation hole portion 10 is not less than the second set value B, and the second set value B satisfies: B = Y × tanα; wherein Y is the opening size of the fourth heat dissipation hole portion 10 along the height direction of the chassis, and α is the preset expansion angle.

[0095] In this embodiment, to optimize the chassis, ensure that the size of the fourth heat dissipation hole section 10 is not limited to 3 mm, and improve heat dissipation, the fourth heat dissipation hole section 10 is provided on the side window 2, and the thickness of the portion of the fourth heat dissipation hole section 10 corresponding to the side window 2 is increased to ensure that the molten material ejected from the fourth heat dissipation hole section 10 can be received by the side window 2. Based on the ignition source flame area 11 and the opening size of the fourth heat dissipation hole section 10 along the height direction of the chassis, trigonometric calculation is used to determine that the thickness of the side window 2 is no less than the second set value B.

[0096] By designing the thickness of the side window 2 and changing the aperture of the fourth heat dissipation hole portion 10, the design is simpler and easier to adjust. When the structural space is limited, it is inconvenient to set the first extended edge 4, the second extended edge 9 and the recessed portion 5. The thickness of the side window 2 can be designed to increase the size of the fourth heat dissipation hole portion 10.

[0097] In some specific application scenarios, such as Figure 6 and Figure 8 As shown, a fourth heat dissipation hole portion 10 is provided on the side window 2, and the opening size of the fourth heat dissipation hole portion 10 along the height direction of the chassis is 11 mm. According to B=Y / cot5°, B=1 mm is calculated. Therefore, when the opening size of the fourth heat dissipation hole portion 10 is 11 mm, the corresponding thickness of the side window 2 is 1 mm.

[0098] In some embodiments, as Figure 6 As shown, when the thickness of the side window 2 takes the limit value, tan5°=B / Y, and reverse deduction yields B=Y / cot5°, cot5°=11.4. Since this is the maximum limit value, cot5° is rounded to 11. The corresponding relationship between the opening size Y of the fourth heat dissipation hole portion 10 along the height direction of the chassis and the second set value B is shown in Table 2:

[0099] Table 2

[0100]

[0101] In one embodiment, Figure 8 As shown, the first extended edge 4 and the fourth heat dissipation hole portion 10 are staggered along a fourth direction, wherein the fourth direction is parallel to the side window 2 .

[0102] In this embodiment, the first extended edge 4 and the fourth heat dissipation hole portion 10 are prevented from interfering with each other. On the same side window 2, the first extended edge 4 and the thickness of the side window 2 can be designed simultaneously according to different needs. Moreover, the first extended edge 4 and the fourth heat dissipation hole portion 10 are not provided on the same side window 2, but can be adjacent to or opposite to each other.

[0103] In one embodiment, Figure 8As shown, the first extended edge 4 is provided on the side window 2 or on the edge of the bottom plate 1 ; and / or the second extended edge 9 is provided on the side window 2 or on the edge of the bottom plate 1 .

[0104] In this embodiment, the first extended edge 4 is connected to the side window 2 by integral molding, welding, or bolting, making the connection more convenient. The first extended edge 4 can be connected to any position of the corresponding side window 2, facilitating the design of the size of the first heat dissipation hole portion 3. The second extended edge 9 is connected to the side window 2 by integral molding, welding, or bolting, making the connection more convenient. The second extended edge 9 can be connected to any position of the corresponding side window 2, facilitating the design of the size of the second heat dissipation hole portion.

[0105] In one embodiment, Figure 4 and Figure 5 As shown, the second extended edge 9 can be connected to any position of the corresponding side window 2, the second extended edge 9 cooperates with the bottom surface 8 of the recessed portion 5, and the sum of the length of the second extended edge 9 and the length of the bottom surface 8 of the recessed portion 5 is not less than the preset length D, and they jointly undertake the part of the ignition source flame area 11 that passes through the second heat dissipation hole portion.

[0106] According to an embodiment of the present application, a second aspect further provides a chassis optimization method, wherein the chassis comprises a bottom plate 1 and a side window 2 connected thereto, and a component 6 is provided in the chassis, wherein the component 6 has an ignition source flame region 11 with a preset expansion angle formed in a direction toward the bottom plate 1, and is applied to a controller, such as Figures 10 to 13 As shown, the structural optimization method includes:

[0107] Step S101: Acquire the ignition source flame area 11.

[0108] Specifically, the process of obtaining the ignition source flame region 11 includes: determining the position of the component 6, and starting from the component 6, expanding outward in both the vertical and horizontal directions to form a conical region. The angle between the generatrix of the conical region and its axis is α, where α is equal to 5. Figure 1 As shown, the maximum horizontal expansion is 15 mm.

[0109] Step S102 : obtaining the opening size of the fourth heat dissipation hole portion 10 on the side window 2 and the actual thickness M of the side window 2 , wherein the fourth heat dissipation hole portion 10 is located in the ignition source flame region 11 .

[0110] Step S103: Determine whether the actual thickness M of the side window 2 satisfies the following condition: M ≥ Y × tanα, where Y is the opening dimension of the fourth heat dissipation hole 10 along the height of the chassis, and α is the preset expansion angle. Using the opening dimension of the fourth heat dissipation hole 10 and the preset expansion angle, and using trigonometric calculations, the minimum thickness of the area of ​​the side window 2 corresponding to the fourth heat dissipation hole 10 can be calculated when the size of the fourth heat dissipation hole 10 is not subject to the 3mm safety regulation limit.

[0111] In some embodiments, when the size of the fourth heat dissipation hole 10 is greater than or equal to 11 mm, the minimum thickness of the side window 2 is 1 mm according to the calculation of M≥Y×tanα.

[0112] Step S104: If not, adjust the actual thickness value M to Y×tanα.

[0113] Specifically, the actual thickness value M of the side window 2 is 1.1 mm, but the opening size of the fourth heat dissipation hole portion 10 along the height direction of the chassis is 13.2 mm. According to trigonometric function calculation, Y×tan5°=1.2 mm, therefore, the actual thickness value M of the side window 2 is adjusted from 1.1 mm to 1.2 mm.

[0114] It should be noted that, if the actual thickness M of the side window 2 satisfies: M≥Y×tanα, and the side window 2 is not provided with a recessed portion 5, step S113 is directly performed.

[0115] Step S105: Obtain the opening dimensions of the second heat dissipation hole portion on the surface of the recessed portion 5 perpendicular to the bottom plate 1, wherein the recessed portion 5 is located on the side window 2. The surface of the recessed portion 5 perpendicular to the bottom plate 1 is the opening surface 7, and the second heat dissipation hole portion is provided on the opening surface 7, which is arranged in the vertical direction.

[0116] Step S106: Determine whether the size of the opening of the second heat dissipation hole portion is greater than a first set value, wherein the first set value is 3 mm, the second heat dissipation hole portion is circular, and the size of the opening of the second heat dissipation hole portion is its diameter.

[0117] Step S107: If yes, the length of the bottom surface 8 of the recessed portion 5 along the direction perpendicular to the side window 2 is obtained. If the opening size of the second heat dissipation hole portion is larger than the first set value, this indicates that the size of the second heat dissipation hole portion does not meet the safety regulation limit of 3mm. The next step is to confirm whether the length of the bottom surface 8 of the recessed portion 5 is sufficient to accommodate the portion of the ignition source flame region 11 that passes through the second heat dissipation hole portion. If the length of the bottom surface 8 of the recessed portion 5 is sufficient to accommodate the portion of the ignition source flame region 11 that passes through the second heat dissipation hole portion, then the length is not less than the target length C. The size of the second heat dissipation hole portion in the chassis recessed portion 5 is greater than 3mm, which complies with safety regulations.

[0118] Step S108: Obtain the opening status of the bottom surface 8 of the recessed portion 5. The opening status includes the size of the opening and whether the opening is open. The size of the opening can be used to determine whether the bottom surface 8 of the recessed portion 5 is defined as a receiving portion. If the opening diameter of the bottom surface 8 of the recessed portion 5 is less than or equal to 3 mm, the bottom surface 8 of the recessed portion 5 can serve as a receiving portion for the ignition source flame region 11.

[0119] Step S109: If the bottom surface 8 of the recessed portion 5 has no opening or the size of the opening is not greater than 3 mm, then the step of determining whether the length of the bottom surface 8 of the recessed portion 5 in a direction perpendicular to the side window 2 is less than the target length C is executed. If the bottom surface 8 of the recessed portion 5 has no opening or the size of the opening is not greater than 3 mm, the bottom surface 8 of the recessed portion 5 can be regarded as a plate. In this case, the bottom surface 8 of the recessed portion 5 can serve as a receiving portion for the portion of the pilot flame region 11 that passes through the second heat dissipation hole portion. This portion is used to receive the portion of the pilot flame region 11 that passes through the second heat dissipation hole portion, so that the melt ejected from the second heat dissipation hole portion cannot pass through the bottom surface 8 of the recessed portion 5 and enter the chassis. Then, it is determined whether the length of the bottom surface 8 of the recessed portion 5 in a direction perpendicular to the side window 2 is less than the target length C. In other words, it is determined whether the length of the bottom surface 8 of the recessed portion 5 can receive the portion of the pilot flame region 11 that passes through the second heat dissipation hole portion, thereby improving the efficiency of chassis structure optimization.

[0120] Step S110: If the opening size of the bottom surface 8 of the recessed portion 5 is larger than 3 mm, the opening size of the second heat dissipation hole is adjusted to 3 mm. When the opening diameter of the second heat dissipation hole is larger than 3 mm, according to safety regulations, the bottom surface 8 of the recessed portion 5 needs to receive the portion of the pilot flame region 11 that passes through the second heat dissipation hole. However, since the opening size of the bottom surface 8 of the recessed portion 5 is larger than 3 mm, it cannot serve as a receiving portion to receive the portion of the pilot flame region 11 that passes through the second heat dissipation hole. Therefore, the opening size of the second heat dissipation hole is adjusted to 3 mm to comply with safety regulations.

[0121] Step S111: Determine whether the length of the bottom surface 8 of the recessed portion 5 along the direction perpendicular to the side window 2 is less than the target length C; wherein C = N × tanα, N is the size of the recessed portion 5 along the height direction of the chassis, and α is the preset expansion angle.

[0122] Step S112: If yes, set a second extended edge 9, wherein the sum of the lengths of the second extended edge 9 and the bottom surface 8 of the recessed portion 5 in the direction perpendicular to the side window 2 is greater than or equal to a preset length D, and the preset length D satisfies: D = S × tanα; wherein S is the distance between the second extended edge 9 and the component 6 in the height direction of the chassis, and α is a preset expansion angle.

[0123] Specifically, if the length of the bottom surface 8 of the recessed portion 5 is less than the target length C, the bottom surface 8 of the recessed portion 5 cannot accommodate the entire portion of the ignition source flame area 11 that passes through the second heat dissipation hole portion. Therefore, the size of the second heat dissipation hole portion provided on the surface of the recessed portion 5 in the direction perpendicular to the bottom plate 1 is limited to 3mm according to safety regulations, resulting in poor heat dissipation effect of the chassis. In order to further optimize the chassis and improve the heat dissipation effect of the chassis, it is necessary to provide a second extended edge 9 to compensate for the defect of insufficient length of the bottom surface 8 of the recessed portion 5, that is, to provide a second extended edge 9 on the side window 2. Figure 4 and Figure 5 As shown, along the direction perpendicular to the side window 2, the sum of the length of the second extended side 9 and the length of the bottom surface 8 of the recessed portion 5 is not less than the preset length D, so that the second extended side 9 and the bottom surface 8 of the recessed portion 5 can jointly bear all of the ignition source flame area 11 that passes through the second heat dissipation hole portion, that is, they can bear the molten material ejected from the second heat dissipation hole portion. Therefore, the size of the second heat dissipation hole portion is greater than 3 mm, which meets the requirements of safety regulations and further improves the heat dissipation effect of the server and the reliability of service operation.

[0124] Specifically, such as Figure 3 As shown, if the length of the bottom surface 8 of the recessed portion 5 is not less than the target length C, it means that the length of the bottom surface 8 of the recessed portion 5 can accommodate the portion of the ignition source flame area 11 that passes through the second heat dissipation hole portion. Therefore, the size of the second heat dissipation hole portion on the recessed portion 5 is not subject to the 3mm limit stipulated by the safety regulations. The size of the second heat dissipation hole portion can be set to be greater than or equal to 5mm, and then the structure of the first heat dissipation hole portion 3 is optimized, and the optimization sequence is progressive.

[0125] Step S113: Obtain the size of the opening of the first heat dissipation hole 3, wherein the first heat dissipation hole 3 is provided on the side window 2 and is located in the ignition source flame region 11. That is, the diameter of the first heat dissipation hole 3 is obtained.

[0126] Step S114: Determine whether the size of the opening on the first heat dissipation hole portion 3 is greater than a first set value, wherein the first set value is 3 mm.

[0127] Step S115 : If yes, a first extended edge 4 is provided in a corresponding area outside the side window 2 , receiving the portion of the ignition source flame area 11 that passes through the first heat dissipation hole portion 3 .

[0128] Specifically, such as Figure 1 and Figure 2As shown, the dimensions of the pilot flame region 11 and the first heat dissipation aperture 3 located within the pilot flame region 11 are first determined. Then, a determination is made as to whether the dimensions of the first heat dissipation aperture 3 are greater than a first set value. If the dimensions of the first heat dissipation aperture 3 are greater than the first set value, this indicates that the dimensions of the first heat dissipation aperture 3 are not within the first set value range specified by safety regulations. Therefore, a first extended edge 4 is provided in the corresponding area outside the side window 2, accommodating the portion of the pilot flame region 11 that extends through the first heat dissipation aperture 3. The first extended edge 4 can receive the melt ejected from the first heat dissipation aperture 3. The dimensions of the first heat dissipation aperture 3 are not limited to 3 mm. Setting the dimensions of the first heat dissipation aperture 3 to be greater than or equal to 5 mm allows the dimensions of the first heat dissipation aperture 3 to be increased while complying with safety regulations, thereby improving the heat dissipation efficiency and service reliability of the server. The first set value is 3 mm. Optimizing the chassis structure through the chassis optimization method can improve optimization efficiency, shorten the chassis structure optimization design cycle, and reduce costs.

[0129] Below is an embodiment, combined with Figures 1 to 14 A comprehensive explanation of all the above plans is given.

[0130] Example 1:

[0131] like Figure 1 、 Figure 2 and Figure 8 As shown, multiple components 6 are arranged within the chassis. During operation, these components 6 are prone to failure and the risk of spontaneous combustion. Upon spontaneous combustion of a component 6, an ignition source flame region 11 with a preset expansion angle is formed. Starting from the component 6, the ignition source flame region 11 expands both horizontally and vertically to form a conical ignition source flame region 11. The size of the openings in the chassis within this region is limited by safety regulations to 3 mm. This prevents molten material generated by the spontaneous combustion of the component 6 from being ejected from the first heat dissipation hole 3 and causing fire hazards.

[0132] However, the size of the opening is 3mm, which is not conducive to heat dissipation from the chassis, and can easily lead to excessive internal temperature of the chassis, reducing the operating efficiency of the components inside the chassis. Therefore, a first extended edge 4 is provided on the outside of the side window 2. Along the height direction of the chassis, the first extended edge 4 is provided below the first heat dissipation hole portion 3. The first extended edge 4 receives the portion where the ignition source flame region 11 passes through the first heat dissipation hole portion 3, that is, it can receive the molten material ejected from the first heat dissipation hole portion 3 after the component 6 spontaneously combusts. Therefore, when the opening size of the first heat dissipation hole portion 3 is greater than 3mm, and the first extended edge 4 is provided on the side window 2, the heat dissipation effect of the chassis and the operating reliability of the components inside the chassis can be improved while complying with safety regulations.

[0133] Further, such as Figure 3As shown, the recessed portion 5 is located within the ignition source flame region 11. A second heat dissipation hole portion is provided on the surface of the recessed portion 5 perpendicular to the bottom plate 1. Specifically, the second heat dissipation hole portion is provided on the opening surface 7. The opening size of the second heat dissipation hole portion is greater than a first set value, where the first set value is 3 mm. The length of the bottom surface 8 of the recessed portion 5 perpendicular to the side window 2 is no less than a target length C. Here, C = N × tanα, where N is the dimension of the recessed portion 5 along the height direction of the chassis and α is the predetermined expansion angle.

[0134] Further, such as Figure 4 and Figure 5 As shown, the length of the bottom surface 8 of the recessed portion 5 in a direction perpendicular to the side window 2 is less than a preset length D, and a second extended edge 9 is connected to the outer side of the side window 2; along the height direction of the chassis, the second extended edge 9 is located below the recessed portion 5 and is arranged in the ignition source flame area 11; along the direction perpendicular to the side window 2, the sum of the length of the second extended edge 9 and the length of the bottom surface 8 of the recessed portion 5 is not less than the preset length D, satisfying: D = S × tanα; wherein S is the distance between the second extended edge 9 and the component 6 along the height direction of the chassis, and α is the preset expansion angle.

[0135] The length of the bottom surface 8 of the recessed portion 5 in a direction perpendicular to the side window 2 is less than a predetermined length D, resulting in the bottom surface 8 of the recessed portion 5 being unable to accommodate the entire portion of the ignition source flame region 11 that passes through the second heat dissipation hole. Therefore, the size of the second heat dissipation hole provided on the surface of the recessed portion 5 in a direction perpendicular to the bottom plate 1 is limited to 3 mm, reducing the heat dissipation effect of the chassis. Therefore, a second extended edge 9 is provided on the side window 2. The second extended edge 9 is arranged in a direction perpendicular to the side window 2. The sum of the length of the second extended edge 9 and the length of the bottom surface 8 of the recessed portion 5 is not less than the predetermined length D. The second extended edge 9 and the bottom surface 8 of the recessed portion 5 jointly accommodate the entire portion of the ignition source flame region 11 that passes through the second heat dissipation hole. By providing the second extended edge 9, the size of the second heat dissipation hole can be greater than or equal to 5 mm.

[0136] Further, such as Figure 6 As shown, the side window 2 is provided with a fourth heat dissipation hole portion 10, the fourth heat dissipation hole portion 10 is located in the ignition source flame area 11, the thickness of the fourth heat dissipation hole portion 10 is not less than the second set value B, and the second set value B satisfies: B = Y × tanα; wherein Y is the opening size of the fourth heat dissipation hole portion 10 along the height direction of the chassis, and α is the preset expansion angle.

[0137] A fourth heat dissipation hole 10 is provided on the side window 2. To ensure that the size of the fourth heat dissipation hole 10 does not exceed the 3 mm limit, the thickness of the portion of the side window 2 corresponding to the fourth heat dissipation hole 10 is increased to ensure that the molten material ejected from the fourth heat dissipation hole 10 can be received by the side window 2. Based on the ignition source flame area 11 and the opening size of the fourth heat dissipation hole 10 along the height of the chassis, trigonometric calculations indicate that the thickness of the side window 2 must be no less than a second set value B. When the thickness of the side window 2 is no less than the second set value B, the size of the fourth heat dissipation hole 10 can be greater than or equal to 5 mm.

[0161] Step S110 : If the size of the opening on the bottom surface 8 of the recessed portion 5 is larger than 3 mm, the size of the opening on the second heat dissipation hole portion is adjusted to 3 mm.
