Description

Technical Field

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

[0002] In related technologies, safety regulations refer to the requirements for product safety in product certification. A product goes through the entire life cycle from design, sales to the end user. This product safety compliance not only includes product safety in the ordinary sense, but also includes requirements in aspects such as electromagnetic compatibility and radiation, energy conservation and environmental protection of the product. It is a product safety responsibility and activity throughout the product life cycle.

[0003] For safety regulations, the opening size requirement for the 5° angle projection area of the ignition source (potential ignition source) inside the chassis should meet not being greater than 3 mm; thus, during the product design process, the opening size within the area projected by the ignition source should all become 3 mm.

[0004] However, a 3 - mm 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, this application provides a chassis, an optimization method, a device, an electronic device, a storage medium, and a program product to solve or improve the problem of poor heat dissipation effect of the server and improve the reliability of service operation.

[0006] In a first aspect, this application provides a chassis with components arranged inside. The chassis includes: A bottom plate, with the components facing the bottom plate direction, forming an ignition source flame area with a preset expansion angle; A side window, connected to the bottom plate. The side window is provided with a first heat dissipation hole part. The first heat dissipation hole part is located within the ignition source flame area, and the opening size on the first heat dissipation hole part is greater than a first set value; A first extension edge is connected to the outside of the side window. The first extension edge is adapted to receive the part of the ignition source flame area that penetrates through the first heat dissipation hole part.

[0007] In this embodiment, multiple components are arranged inside the chassis. During operation, the components are prone to failure and have a risk of spontaneous combustion. After a component undergoes spontaneous combustion, an ignition source flame area with a preset expansion angle is formed. The ignition source flame area starts from the component and expands simultaneously in the horizontal and vertical directions, forming a conical ignition source flame area. The opening size of the part of the chassis within this area is restricted by safety regulations, and the opening size is restricted to 3 mm to prevent the molten matter generated by the spontaneous combustion of the component from spraying out of the chassis through the first heat dissipation hole part and causing hazards such as fires.

[0008] 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.

[0009] 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: Obtain the flame area of the ignition source; 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; Determining whether the size of the opening on the first heat dissipation hole portion is greater than a first set value; 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.

[0010] In a third aspect, the present application provides an optimization device, comprising: 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; 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; 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.

[0011] 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.

[0012] In a fifth aspect, the present application provides a computer-readable storage medium, on which computer instructions are stored, and the computer instructions are used to enable a computer to execute a chassis optimization method.

[0013] In a sixth aspect, the present application provides a computer program product comprising computer instructions for causing a computer to execute a chassis optimization method. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some, but not all, of the embodiments of the present application.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0020] In related technologies, safety regulations refer to the requirements for product safety in product certification. The product goes through the entire life cycle of product use from design, sales to the end user. This product safety compliance not only includes product safety in the ordinary sense, but also includes requirements in aspects such as electromagnetic compatibility and radiation, energy conservation and environmental protection of the product, and is a product safety responsibility and activity throughout the product life cycle.

[0021] For safety regulations, the opening size requirement for the 5° angle projection area of PIS (Potential Ignition Source) inside the chassis should meet not greater than 3 mm; thus, during the product design process, the opening sizes within the projected area of the ignition source should all be changed to 3 mm.

[0022] However, a 3-mm opening cannot guarantee the heat dissipation requirements of the server and affects the reliability of the server operation. For this reason, the present application provides a chassis, a structure optimization method, a device, a computer, a medium, and a program product to solve or improve the problem of poor heat dissipation effect of the server and improve the reliability of service operation.

[0023] The following will Figures 1 to 14 describe the embodiments of the present application.

[0024] According to the embodiments of the present application, on the one hand, as Figure 1 shown, a chassis is provided, with components 6 arranged inside. The chassis includes: a bottom plate 1 and a side window 2. The bottom plate 1 and the side window 2 are perpendicularly arranged. The bottom plate 1 is arranged in the horizontal direction, and the side window 2 is arranged in the vertical direction.

[0025] The components 6 mainly refer to the parts that are prone to spontaneous combustion in the present application, and the components 6 belong to a type of PIS.

[0026] In safety regulation design, the fire prevention design of the chassis is the focus of safety regulation design. According to the regulations, the flame model is divided into resistive PIS (Potential Ignition Source) and arcing PIS. The resistive PIS is located in the circuits of PS2 (an interface on the computer system, mainly used to connect input devices such as keyboards and mice) or PS3 (a power supply with a high power level). After normal operation for 30 s, the measured power is greater than 15 W, or after a single fault within 30 s, the measured power is greater than 100 W, or after a single fault for 30 s, the measured power is greater than 15 W. The arcing PIS is the possible disconnected connection parts located in the PS2 or PS3 circuits, such as switches, terminals, and copper foils on the printed circuit board. After 3 s, the measured open-circuit voltage is greater than 50 Vpeak (peak value), and the product of the rms (equivalent current) and the peak voltage is greater than 15. Therefore, in circuit design, the PIS can be a point, or the components 6, or the printed lines on the printed circuit board. When actually judged in the product certification laboratory, the (Personal Identification Number) close to the electronic product, the components 6, and the PCB (Printed Circuit Board) traces will all be defined as PIS.

[0027] Specifically, as Figure 1As shown, component 6 serves as a potential ignition source. Component 6 faces the direction of the bottom plate 1, forming an ignition source flame region 11 with a preset expansion angle. The ignition source flame region 11 is a conical region that starts from component 6 and spreads outward in the direction of the bottom plate 1. The angle between the generatrix of the conical region and its axis is α, which is also the angle between the boundary of the ignition source flame region 11 and the vertical direction. Among them, the preset expansion angle α is equal to 5°. Starting from component 6, the maximum value of the length of the conical region expanding in the horizontal direction is 15 mm.

[0028] Specifically, as Figure 1 、 Figure 2 and Figure 8 shown, the side window 2 is connected to the bottom plate 1. The side window 2 is provided with a first heat dissipation hole portion 3. The first heat dissipation hole portion 3 is located within the ignition source flame region 11. The opening size on the first heat dissipation hole portion 3 is greater than a first set value. Among them, the first set value is 3 mm. The first heat dissipation hole portion 3 includes a plurality of first heat dissipation holes. The plurality of first heat dissipation holes are arranged in an array on the first heat dissipation hole portion 3. The array arrangement can be a matrix arrangement or a circular array arrangement. And the first heat dissipation holes can be regular shapes such as circular, elliptical, or square, or other special-shaped configurations. 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.

[0029] It should be noted that the side window 2 can be the front window or the rear window of the chassis or the side plate between the front window and the rear window.

[0030] Specifically, as Figure 1 、 Figure 2 and Figure 8 shown, a first extension edge 4 is connected to the outside of the side window 2. The first extension edge 4 is adapted to receive the part of the ignition source flame region 11 that penetrates through the first heat dissipation hole portion 3. Among them, the first extension edge 4 is a plate-like structure. The first extension edge 4 is fixedly connected to the side window 2 and is perpendicularly arranged. The connection method can be an integrally formed connection, a welded connection, or a bolt connection.

[0031] In some unshown embodiments, the first extension edge 4 can be arranged at an angle with the side window 2 to ensure that the length of the first extension edge 4 along the direction perpendicular to the side window 2 can receive the part of the ignition source flame region 11 that penetrates through the first heat dissipation hole portion 3.

[0032] In some embodiments, as Figure 1 、 Figure 2 and Figure 8As shown in the figure, multiple components 6 are arranged inside the chassis. During operation, the components 6 are prone to failure and have a risk of spontaneous combustion. After the components 6 catch fire spontaneously, the molten material is ejected to form an ignition source flame area 11 with a preset expansion angle. The ignition source flame area 11 starts from the component 6 and expands simultaneously in the horizontal and vertical directions to form a conical ignition source flame area 11. The opening size of the part of the chassis located within this area is restricted by safety regulations, and the opening size is limited to 3 mm to prevent the molten material generated by the spontaneous combustion of the component 6 from spraying out of the chassis through the first heat dissipation hole part 3 and causing hazards such as fires.

[0033] However, an opening size of 3 mm is not conducive to the heat dissipation of the chassis and easily leads to an excessively high temperature inside the chassis, reducing the operating efficiency of the components inside the chassis. Therefore, a first extension edge 4 is provided outside the side window 2. Along the height direction of the chassis, the first extension edge 4 is arranged below the first heat dissipation hole part 3. The first extension edge 4 receives the part of the ignition source flame area 11 that penetrates through the first heat dissipation hole part 3, that is, it can receive the molten material ejected from the first heat dissipation hole part 3 after the component 6 catches fire spontaneously. Therefore, when the opening size of the first heat dissipation hole part 3 is greater than 3 mm and the first extension 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 meeting safety regulations.

[0034] In one embodiment, as Figure 3 shown, the side window 2 has a recessed part 5. Specifically, the recessed direction of the recessed part 5 is perpendicular to the side window 2 and towards the inside of the chassis. An opening surface 7 perpendicular to the bottom plate 1 and a bottom surface 8 parallel to the bottom plate 1 are formed inside the recessed part 5. The second heat dissipation hole part is opened on the opening surface 7.

[0035] In an embodiment not shown, the top surface corresponding to the bottom surface 8 inside the recessed part 5 can be parallel to the bottom surface 8 or not parallel to the bottom surface 8. In the state where the top surface is not parallel to the bottom surface 8, the top surface extends upward and away from the side window 2, then the opening of the recessed part 5 is a flared opening, which is convenient for the second heat dissipation hole part to dissipate heat; the top surface extends downward and away from the side window 2, then the opening of the recessed part 5 is a constricted opening, which can improve the dust-proof effect of the second heat dissipation hole part.

[0036] Specifically, as Figure 3 shown, the recessed part 5 is a groove, and the groove is integrally formed by stamping with the side window 2.

[0037] 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, 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; 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.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] 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.

[0042] In one embodiment, Figure 4 and Figure 5As shown, the bottom surface 8 of the recess 5 is provided with a third heat dissipation hole portion. When the opening size of the third heat dissipation hole portion is not greater than a first set value, that is, when the size of the third heat dissipation hole portion is not greater than 3 mm, when the components 6 inside the chassis catch fire spontaneously, the molten matter generated will not be ejected from the second heat dissipation hole portion onto the bottom surface 8 of the recess 5 and sprayed into the chassis through the provided third heat dissipation hole portion. Therefore, setting the third heat dissipation hole portion on the bottom surface 8 of the recess 5 can further improve the heat dissipation effect of the chassis.

[0043] In some embodiments, the third heat dissipation hole portion includes a plurality of third heat dissipation holes, and the third heat dissipation holes can be regular shapes such as circular, oval, square, etc. or other special-shaped shapes. Specifically, the third heat dissipation hole is circular, and the diameter of the second heat dissipation hole is not greater than 3 mm.

[0044] In one embodiment, as Figure 1 shown, the length of the first extended side 4 extending in a direction perpendicular to the side window 2 is a target length A, satisfying: A≥L×tanα; where L is the distance between the first extended side 4 and the component 6 in the height direction of the chassis, and α is a preset expansion angle.

[0045] It should be noted that the target length A is the length of the projection of the first extended side 4 on a plane perpendicular to the side window 2. Therefore, the first extended side 4 may not be perpendicular to the side window 2.

[0046] Specifically, as Figure 7 shown, the height of the chassis can be divided into 1U, 2U, 3U, 4U, 5U, 6U, 7U, 8U, 9U, 10U, etc. Among them, 1U = 1.75 inches = 44.45 mm. So when L = 44.45 mm, A = 44.45 mm×tan5° = 44.45 mm×0.0875 = 3.889375 mm. Therefore, when the height of the chassis is 1U, the length of the first extended side 4 is greater than or equal to 3.889375 mm and is set at the bottom of the corresponding side window 2 of the chassis, and the size of the first heat dissipation hole opened on the side window 2 is greater than or equal to 5 mm. The degree of α is 5°.

[0047] Specifically, as Figure 7 shown, 2U = 13.5 inches = 88.9 mm. So when L = 88.9 mm, A = 88.9 mm×tan5° = 88.9 mm×0.0875 = 7.77875 mm. Therefore, when the height of the chassis is 2U, the length of the first extended side 4 is greater than or equal to 7.77875 mm and is set at the bottom of the corresponding side window 2 of the chassis, and the size of the first heat dissipation hole opened on the side window 2 is greater than or equal to 5 mm. The degree of α is 5°.

[0048] In a specific application scenario, as Figure 1 、 Figure 2 andFigure 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 extension side 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 extension side 4 and the component 6 in the height direction of the chassis is 2U, that is, L = 88.9 mm, and α is a preset expansion angle of 5°. According to A ≥ L×tanα, the minimum value of A is 7.77875 mm.

[0049] In a specific application, according to the ignition source flame region 11 and the distance between the first extension side 4 and the component 6 in the height direction of the chassis, the target length A corresponding to the component 6 at different heights can be calculated through trigonometric functions.

[0050] Specifically, according to the above calculation method, the length L of the first extension side 4 corresponding to when the height of the chassis is 3U, 4U, 5U, 6U, 7U, 8U, 9U, 10U, etc. can be calculated respectively, as shown in Table 1: Table 1

[0051] It should be noted that as Figure 1 and Figure 2 shown, the component 6 is a potential ignition source. Starting from the component 6, the maximum value of the length of the conical region expanding in the horizontal direction is 15 mm. Therefore, when the first extension side 4 is perpendicularly arranged with the side window 2, the limit value of the length of the first extension side 4 in the horizontal direction is 15 mm, where the direction perpendicular to the side window 2 is parallel to the horizontal direction. Therefore, the maximum value of the target length A is 15 mm.

[0052] In an embodiment, as Figure 4 and Figure 5 shown, the length of the bottom surface 8 of the recessed portion 5 in the direction perpendicular to the side window 2 is less than the preset length D. A second extension side 9 is connected to the outside of the side window 2. Specifically, the second extension side 9 is a plate-like structure. The second extension side 9 can be perpendicularly arranged with the side window 2 or not. When the second extension side 9 is not perpendicularly arranged with the side window 2, the length of the second extension side 9 refers to its projection length on the plane perpendicular to the side window 2. When the second extension side 9 is perpendicularly arranged with the side window 2, the length of the second extension side 9 refers to the length in the direction perpendicular to the side window 2. Among them, the second extension side 9 is fixedly connected to the side window 2, and the connection method can be integral molding connection, welding connection, or bolt connection.

[0053] In the height direction of the chassis, as Figure 4 and Figure 5As 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.

[0054] 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.

[0055] In some embodiments, as Figure 4 and Figure 5 As 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.

[0056] 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.

[0057] In some specific application scenarios, such as Figure 4 and Figure 5As shown, the sum of the length of the second extension side 9 and the length of the bottom surface 8 of the recess 5 is equal to the preset length D. Specifically, the height of the chassis is 1U, where 1U = 1.75 inches = 44.45 mm. Therefore, when L = 44.45 mm, A ≥ 44.45 mm × tan5° = 44.45 mm × 0.0875 = 3.889375 mm. If a heat dissipation hole with a size of more than 5 mm is designed in the side window 2 of the chassis with a height between 1U and 2U, we can retract the side window 2 of the chassis with a height between 1U and 2U by a distance of the target length C in the direction perpendicular to it and towards the inside of the chassis to form a recess 5. The length of the bottom surface 8 of the recess 5 is the target length C, where C = N × tanα, N is the height of 1U, that is, 44.45 mm, and α is 5°. The calculated target length C is 3.889375 mm.

[0058] In some embodiments, as Figure 4 and Figure 5 shown, if a heat dissipation hole with a size of more than 5 mm is designed in the side window 2 of the chassis with a height between 1U and 2U, we can retract the side window 2 of the chassis with a height between 1U and 2U by a distance of the target length C in the direction perpendicular to it and towards the inside of the chassis to form a recess 5. The length of the bottom surface 8 of the recess 5 is the target length C. However, if the calculated target length C is less than 3.889375 mm, a second extension side 9 needs to be provided on the side window 2. The second extension side 9 is located below the recess 5 in the height direction of the chassis. The second extension side 9 is provided to make up for the defect of the insufficient length of the bottom surface 8 of the recess 5. The second extension side 9 extends in the direction perpendicular to the side window 2. When the sum of the lengths of the second extension side 9 and the bottom surface 8 of the recess 5 in the direction perpendicular to the side window 2 satisfies the condition of being greater than or equal to the preset length D, the second extension side 9 and the bottom surface 8 of the recess 5 can jointly receive the part of the ignition source flame area 11 passing through the second heat dissipation hole part. Thus, the size of the second heat dissipation hole part is greater than 3 mm, meeting the safety regulations and further improving the heat dissipation effect of the server and the reliability of service operation.

[0059] In some embodiments, the preset length D = S × tanα, where S is the distance between the second extension side 9 and the component 6 in the height direction of the chassis, and α is 5°. As Figure 5 shown, taking the second extension side 9 being set at the bottom of the side window 2 as an example, at this time, S is 2U, 2U = 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 extension side 9 is equal to 7.77875 mm minus the length of the bottom surface 8 of the recess 5.

[0060] Different from the above embodiments, as Figure 4As shown, taking the case where the second extended side 9 is set at the height between the bottom plate 1 and 1U as an example, at this time, S is the distance between the second extended side 9 and the component 6 in the height direction of the chassis.

[0061] In some embodiments, when designing heat dissipation holes with a size greater than 5 mm in the side window 2 of a chassis with a height between 0.5U and 1U, we can retract the side window 2 of the chassis with a height between 0.5U and 1U by a target length C in a direction perpendicular to it and towards the interior of the chassis to form a recess 5. The length of the bottom surface 8 of the recess 5 is the target length C, where C = N×tanα, N is the height of 0.5U, that is, 22.225 mm, and α is 5°. The calculated target length C is 1.9446875 mm.

[0062] In specific applications, such as Figure 4 、 Figure 5 and Figure 8 As shown, there is a recess 5 provided on the side window 2, and a second heat dissipation hole part is provided on the opening surface 7 of the recess 5. The length of the bottom surface 8 of the recess 5 in the direction perpendicular to the side window 2 is 2 mm, and the perpendicular distance between the component 6 and the bottom surface 8 of the recess 5 is 1U, that is, 44.45 mm. According to the target length C = N×tan5° = 3.889375 mm. However, the length of the bottom surface 8 of the recess 5 is only 2 mm. Therefore, a second extended side 9 needs to be provided below the recess 5. The second extended side 9 is arranged perpendicular to the side window 2, and the distance between the second extended side 9 and the component 6 in the height direction of the chassis is 2U, that is, 88.9 mm. So 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 side 9 = 7.77875 mm - 2 mm = 5.77875 mm.

[0063] In one embodiment, as Figure 8 shown, the first extended side 4 and the recess 5 are arranged out of position in a third direction, where the third direction is parallel to the side window 2, and the third direction is the same as the fourth direction.

[0064] In some embodiments, as Figure 8 shown, on the same side window 2, the first extended side 4 and the recess 5 can be designed simultaneously according to different requirements. And on the same side window 2, the first extended side 4, as well as the recess 5 and the second extended side 9, can be designed simultaneously according to different requirements.

[0065] In some embodiments, the first extended side 4 and the recess 5 are not provided on the same side window 2, and they can be adjacent side windows 2 or opposite side windows 2.

[0066] In one embodiment, as Figure 6 andFigure 8 As shown, a fourth heat dissipation hole portion 10 is provided on the side window 2. The fourth heat dissipation hole portion 10 is located within the ignition source flame region 11. The thickness of the fourth heat dissipation hole portion 10 is not less than a second set value B, and the second set value B satisfies: B = Y × tanα; where Y is the opening size of the fourth heat dissipation hole portion 10 in the height direction of the chassis, and α is a preset expansion angle.

[0067] In this embodiment, to optimize the chassis, ensure that the size of the fourth heat dissipation hole portion 10 is not limited by 3 mm, improve the heat dissipation effect, by providing the fourth heat dissipation hole portion 10 on the side window 2, increasing the thickness of the portion of the fourth heat dissipation hole portion 10 corresponding to the side window 2, ensuring that the molten material ejected from the fourth heat dissipation hole portion 10 can be received by the side window 2. According to the ignition source flame region 11 and the opening size of the fourth heat dissipation hole portion 10 in the height direction of the chassis, through trigonometric calculation, it is obtained that the thickness of the side window 2 is not less than the second set value B.

[0068] By designing the thickness of the side window 2, 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 and it is not convenient to provide the first extension edge 4, the second extension 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.

[0069] 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. The opening size of the fourth heat dissipation hole portion 10 in the height direction of the chassis is 11 mm. According to B = Y / cot5°, it is calculated that B = 1 mm. 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.

[0070] In some embodiments, such as Figure 6 As shown, when the thickness of the side window 2 takes the limit value, tan5° = B / Y, and by reverse deduction, B = Y / cot5° is obtained. cot5° = 11.4. Since it is to calculate the maximum limit value, after rounding up cot5°, it is 11. The corresponding relationship between the opening size Y of the fourth heat dissipation hole portion 10 in the height direction of the chassis and the second set value B is shown in Table 2: Table 2

[0071] In one embodiment, such as Figure 8 As shown, the first extension edge 4 is arranged out of alignment with the fourth heat dissipation hole portion 10 in the fourth direction, where the fourth direction is parallel to the side window 2.

[0072] In this embodiment, the first extended edge 4 and the fourth heat dissipation hole portion 10 are prevented from affecting each other. On the same side window 2, according to different requirements, the first extended edge 4 can be designed and the thickness of the side window 2 can be increased at the same time. In addition, when the first extended edge 4 and the fourth heat dissipation hole portion 10 are not provided on the same side window 2, they can be adjacent side windows 2 or opposite side windows 2.

[0073] In one embodiment, as Figure 8 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.

[0074] In this embodiment, the first extended edge 4 is connected to the side window 2 by integral molding, welding or bolt connection, which makes 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 bolt connection, which makes 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.

[0075] In one embodiment, as Figure 4 and Figure 5 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, jointly receiving the part of the ignition source flame area 11 passing through the second heat dissipation hole portion.

[0076] According to an embodiment of the present application, in a second aspect, a chassis optimization method is further provided. The chassis includes a bottom plate 1 and a side window 2 connected to each other. Components 6 are provided in the chassis. The components 6 have a direction towards the bottom plate 1, forming an ignition source flame area 11 with a preset expansion angle, which is applied to a controller. As Figures 10 to 13 shown, the structural optimization method includes: Step S101: Obtain the ignition source flame area 11.

[0077] Specifically, the process of obtaining the ignition source flame area 11 includes: determining the position of the component 6, and starting from the component 6, expanding outward simultaneously in the vertical and horizontal directions to form a conical area. The angle between the generatrix of the conical area and its axis is α, where α is equal to 5. As Figure 1 shown, the maximum value of the horizontal expansion is 15 mm.

[0078] Step S102: Obtain the opening size of the fourth heat dissipation hole part 10 on the side window 2 and the actual thickness value M of the side window 2, where the fourth heat dissipation hole part 10 is located within the ignition source flame area 11.

[0079] Step S103: Determine whether the actual thickness value M of the side window 2 satisfies: M≥Y×tanα, where Y is the opening size of the fourth heat dissipation hole part 10 in the height direction of the chassis, and α is a preset expansion angle. Through the opening size of the fourth heat dissipation hole part 10 and the preset expansion angle, and based on trigonometric calculations, it is possible to calculate the minimum thickness of the area of the side window 2 corresponding to the fourth heat dissipation hole part 10 when the size of the fourth heat dissipation hole part 10 is not restricted by the 3mm specified in the safety regulations.

[0080] In some embodiments, when the size of the fourth heat dissipation hole part 10 is greater than or equal to 11mm, through the calculation of M≥Y×tanα, the minimum thickness of the side window 2 is 1mm.

[0081] Step S104: If not, then adjust the actual thickness value M to Y×tanα.

[0082] Specifically, the actual thickness value M of the side window 2 is 1.1mm, but the opening size of the fourth heat dissipation hole part 10 in the height direction of the chassis is 13.2mm. According to trigonometric calculations, Y×tan5° = 1.2mm. Therefore, the actual thickness value M of the side window 2 is adjusted from 1.1mm to 1.2mm.

[0083] It should be noted that if the actual thickness value M of the side window 2 satisfies: M≥Y×tanα, and the side window 2 is not provided with the recessed part 5, then directly proceed to step S113. Step S105: Obtain the opening size of the second heat dissipation hole part on the surface of the recessed part 5 along the direction perpendicular to the bottom plate 1, where the recessed part 5 is located on the side window 2. The surface of the recessed part 5 along the direction perpendicular to the bottom plate 1 is the opening surface 7, the second heat dissipation hole part is provided on the opening surface 7, and the opening surface 7 is arranged in the vertical direction.

[0084] Step S106: Determine whether the opening size on the second heat dissipation hole part is greater than the first set value. The first set value is 3mm, the second heat dissipation hole part is circular, and the opening size of the second heat dissipation hole part is its diameter.

[0085] Step S107: If so, obtain the length of the bottom surface 8 of the recess 5 along the direction perpendicular to the side window 2. The opening size of the second heat dissipation hole part is greater than the first set value, indicating that the size of the second heat dissipation hole part does not meet the size limit of 3 mm specified by safety regulations. Then, the next step is to confirm whether the length of the bottom surface 8 of the recess 5 can hold the part of the ignition source flame area 11 passing through the second heat dissipation hole part. If the length of the bottom surface 8 of the recess 5 can hold the part of the ignition source flame area 11 passing through the second heat dissipation hole part, it means that its length is not less than the target length C. The size of the second heat dissipation hole part on the chassis recess 5 is greater than 3 mm, which meets the safety regulations.

[0086] Step S108: Obtain the opening state of the bottom surface 8 of the recess 5. Among them, the opening state includes the size of the opening and whether there is an opening. According to the size of the opening, it can be judged whether the bottom surface 8 of the recess 5 is defined as a receiving part. If the opening diameter of the bottom surface 8 of the recess 5 is less than or equal to 3 mm, then the bottom surface 8 of the recess 5 can be used as a receiving part for receiving the ignition source flame area 11.

[0087] Step S109: If there is no opening or the opening size of the bottom surface 8 of the recess 5 is not greater than 3 mm, then execute the step: judge whether the length of the bottom surface 8 of the recess 5 along the direction perpendicular to the side window 2 is less than the target length C. When there is no opening or the opening size of the bottom surface 8 of the recess 5 is not greater than 3 mm, the bottom surface 8 of the recess 5 can be regarded as a plate body. At this time, the bottom surface 8 of the recess 5 can be used as a receiving part for receiving the part of the ignition source flame area 11 passing through the second heat dissipation hole part, so that the molten material ejected from the second heat dissipation hole part cannot enter the chassis through the bottom surface 8 of the recess 5. Then, judge whether the length of the bottom surface 8 of the recess 5 along the direction perpendicular to the side window 2 is less than the target length C, that is, judge whether the length of the bottom surface 8 of the recess 5 can hold the part of the ignition source flame area 11 passing through the second heat dissipation hole part, so as to improve the efficiency of chassis structure optimization.

[0088] Step S110: If the opening size of the bottom surface 8 of the recess 5 is greater than 3 mm, then adjust the opening size on the second heat dissipation hole part to 3 mm. When the opening diameter of the second heat dissipation hole part is greater than 3 mm, according to safety regulations, the bottom surface 8 of the recess 5 needs to receive the part of the ignition source flame area 11 passing through the second heat dissipation hole part. However, the opening size of the bottom surface 8 of the recess 5 is greater than 3 mm and cannot be used as a receiving part to receive the part of the ignition source flame area 11 passing through the second heat dissipation hole part. Therefore, the opening size on the second heat dissipation hole part is adjusted to 3 mm to meet the safety regulations.

[0089] Step S111: Judge whether the length of the bottom surface 8 of the recess 5 along the direction perpendicular to the side window 2 is less than the target length C; where C = N × tanα, N is the size of the recess 5 along the height direction of the chassis, and α is a preset expansion angle.

[0090] 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.

[0091] 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.

[0092] 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.

[0093] 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.

[0094] 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.

[0095] 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 .

[0096] Specifically, such as Figure 1 and Figure 2 As 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.

[0097] Below is an embodiment, combined with Figures 1 to 14 A comprehensive explanation of all the above plans is given.

[0098] Example 1: 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.

[0099] 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.

[0100] Further, as Figure 3 shown, the recess 5 is located within the ignition source flame region 11. A second heat dissipation hole portion is provided on the surface of the recess 5 along the direction perpendicular to the bottom plate 1, that is, the second heat dissipation hole portion is provided on the opening surface 7, and 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 recess 5 along the direction perpendicular to the side window 2 is not less than the target length C; where C = N × tan α, N is the dimension of the recess 5 along the height direction of the chassis, and α is a preset expansion angle.

[0101] Further, as Figure 4 and Figure 5 shown, the length of the bottom surface 8 of the recess 5 along the direction perpendicular to the side window 2 is less than a preset length D. A second extension edge 9 is connected to the outside of the side window 2; along the height direction of the chassis, the second extension edge 9 is located below the recess 5 and is arranged within the ignition source flame region 11; along the direction perpendicular to the side window 2, the sum of the length of the second extension edge 9 and the length of the bottom surface 8 of the recess 5 is not less than the preset length D, satisfying: D = S × tan α; where S is the distance between the second extension edge 9 and the component 6 along the height direction of the chassis, and α is a preset expansion angle.

[0102] The length of the bottom surface 8 of the recess 5 along the direction perpendicular to the side window 2 is less than the preset length D, resulting in the bottom surface 8 of the recess 5 being unable to receive all of the part of the ignition source flame region 11 that penetrates the second heat dissipation hole portion. Therefore, the size of the second heat dissipation hole portion provided on the surface of the recess 5 along the direction perpendicular to the bottom plate 1 is limited to 3 mm, reducing the heat dissipation effect of the chassis. Therefore, a second extension edge 9 is provided on the side window 2. The second extension edge 9 is arranged along the direction perpendicular to the side window 2, and the sum of the length of the second extension edge 9 and the length of the bottom surface 8 of the recess 5 is not less than the preset length D. The second extension edge 9 and the bottom surface 8 of the recess 5 jointly receive all of the part of the ignition source flame region 11 that penetrates the second heat dissipation hole portion. By providing the second extension edge 9, the size of the second heat dissipation hole portion can be greater than or equal to 5 mm.

[0103] Further, as Figure 6 shown, the side window 2 is provided with a fourth heat dissipation hole portion 10. The fourth heat dissipation hole portion 10 is located within the ignition source flame region 11, and the thickness of the fourth heat dissipation hole portion 10 is not less than a second set value B, and the second set value B satisfies: B = Y × tan α; where Y is the opening size of the fourth heat dissipation hole portion 10 along the height direction of the chassis, and α is a preset expansion angle.

[0104] A fourth heat dissipation hole part 10 is arranged on the side window 2. To ensure that the size of the fourth heat dissipation hole part 10 is not limited by 3 mm, by increasing the thickness of the part of the side window 2 corresponding to the fourth heat dissipation hole part 10, it is ensured that the melt ejected from the fourth heat dissipation hole part 10 can be received by the side window 2. According to the ignition source flame area 11 and the opening size of the fourth heat dissipation hole part 10 in the height direction of the chassis, through trigonometric calculation, the thickness of the side window 2 is not less than the second set value B. When the thickness of the side window 2 is not less than the second set value B, the size of the fourth heat dissipation hole part 10 can be greater than or equal to 5 mm.
