DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solutions and advantages of the present application more clear, the following will combine the drawings in the present application to clearly and completely describe the technical solutions in the present application. Obviously, the described embodiments are some embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0027] The following will combine Figures 1 to 4 to describe the memory device of the blade server and the blade server of the present application.

[0028] As Figure 1 , Figure 2 and Figure 3As shown, the memory device of the blade server in this embodiment of the present invention includes: a housing 1, a fastener 3, and a memory component 2.

[0029] The housing 1 includes a first cover plate 11 and a second cover plate 12. Both the first cover plate 11 and the second cover plate 12 can be rectangular structural members. Both the first cover plate 11 and the second cover plate 12 can be made of materials with high heat dissipation efficiency, for example, both the first cover plate 11 and the second cover plate 12 can be metal plates. The first cover plate 11 is provided with a first support portion 111, and the second cover plate 12 is provided with a second support portion 121. Both the first support portion 111 and the second support portion 121 can be columnar structural members.

[0030] Additionally, the memory component 2 includes memory chips 22 and a first circuit board 21. The first circuit board 21 can be a rectangular structure. The memory chips 22 are mounted on the first circuit board 21. For example, two rows of memory chips 22 are arranged on the front and two rows of memory chips 22 are arranged on the back of the first circuit board 21. Furthermore, the first circuit board 21 is located between the first support portion 111 and the second support portion 121. Each corner of the first cover plate 11 has a first support portion 111, resulting in four first support portions 111. Each corner of the second cover plate 12 has a second support portion 121, resulting in four second support portions 121. At this time, both ends of the first circuit board 21 are sandwiched between the first support portions 111 and the second support portions 121. Fasteners 3 are sequentially inserted into the first support portion 111, the first circuit board 21, and the second support portion 121. The gold fingers of the first circuit board 21 are exposed outside the housing 1.

[0031] It should be noted that both the first support portion 111 and the second support portion 121 have a certain height. In this way, when the first circuit board 21 is located between the first support portion 111 and the second support portion 121, interference between the memory chip 22 and the first cover plate 11 and the second cover plate 12 can be avoided.

[0032] It is understandable that the first cover plate 11 and the second cover plate 12 can be made of 7075 aluminum alloy. In addition, the first cover plate 11 and the second cover plate 12 have undergone surface treatment in advance. The surface treatment process involves first performing fine sandblasting, and then performing anodizing and anti-fingerprint coating processes.

[0033] The memory device of the blade server in this embodiment of the utility model has a first circuit board 21 embedded and fixed between the first cover plate 11 and the second cover plate 12, with only the gold fingers on the first circuit board 21 exposed for plugging into the corresponding connector 6. The overall structure is simple and reliable and easy to install.

[0034] In practical applications, such as Figure 1 ,Figure 2 and Figure 3 As shown in Figs. 1, 2 and 3, the edge of the first cover plate 11 is provided with a first avoiding opening 113 at the position corresponding to the gold finger, and the edge of the second cover plate 12 is provided with a second avoiding opening 123 at the position corresponding to the gold finger. The assembling space formed by the first avoiding opening 113 and the second avoiding opening 123 is adapted to the connector 6, and the connector 6 is arranged in the assembling space and connected with the gold finger, so that the compactness of the overall structure can be ensured. It should be noted that the gold finger is provided with a clamping groove adapted to the buckle on the connector 6. For example, the gold finger is provided with three clamping grooves, which are arranged at intervals along the length direction of the first circuit board 21.

[0035] In an alternative embodiment, as shown in Figs. 4, 5 and 6, the fastener 3 is provided with an external thread, the first supporting part 111 is provided with a first threaded hole 1111 adapted to the external thread, the second supporting part 121 is provided with a counterbore 1211, and the first circuit board 21 is provided with a through hole 212. The fastener 3 is sequentially arranged in the counterbore 1211 and the through hole 212, and is threadedly connected to the first threaded hole 1111. Figure 1 Figure 2 Figure 3 It should be noted that the first threaded hole 1111 and the counterbore 1211 are both through holes. The fastener 3 can be a counterbore hexagonal socket head screw. In this way, under the connection of the fastener 3, the fixed connection of the first cover plate 11, the first circuit board 21 and the second cover plate 12 can be achieved.

[0036] In an alternative embodiment, as shown in Figs. 7, 8 and 9, the first cover plate 11 includes a first bottom wall and a first side wall connected with each other, and the first supporting part 111 is arranged on the first bottom wall and located at the corner of the first side wall. The first bottom wall, the first side wall and the first supporting part 111 can be integrally formed, and in addition, the first bottom wall and the first side wall are missing at the positions corresponding to the gold finger to form the first avoiding opening 113. It should be particularly pointed out that the sum of the heights of the first circuit board 21 and the first supporting part 111 is less than or equal to the height of the first side wall. In this way, the first cover plate 11 can form a semi-enclosure for the first circuit board 21, thereby effectively protecting the structure of the first circuit board 21.

[0037] Similarly, the second cover plate 12 includes a second bottom wall and a second side wall connected with each other, and the second supporting part 121 is arranged on the second bottom wall and located at the corner of the second side wall. The second bottom wall, the second side wall and the second supporting part 121 can be integrally formed, and in addition, the second bottom wall and the second side wall are missing at the positions corresponding to the gold finger to form the second avoiding opening 123. The height of the second supporting part 121 is equal to the height of the second side wall. Figure 1 Figure 2 Figure 3 It should be noted that the first threaded hole 1111 and the counterbore 1211 are both through holes. The fastener 3 can be a counterbore hexagonal socket head screw. In this way, under the connection of the fastener 3, the fixed connection of the first cover plate 11, the first circuit board 21 and the second cover plate 12 can be achieved.

[0038] Similarly, the second cover plate 12 includes a second bottom wall and a second side wall connected with each other, and the second supporting part 121 is arranged on the second bottom wall and located at the corner of the second side wall. The second bottom wall, the second side wall and the second supporting part 121 can be integrally formed, and in addition, the second bottom wall and the second side wall are missing at the positions corresponding to the gold finger to form the second avoiding opening 123. The height of the second supporting part 121 is equal to the height of the second side wall. ​​​​

[0039] In an alternative embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, the first cover plate 11 is also provided with a first positioning post 112, and the first circuit board 21 is provided with a first positioning hole 211 that is adapted to the first positioning post 112; the second cover plate 12 is also provided with a second positioning post 122, and the first circuit board 21 is provided with a second positioning hole 213 that is adapted to the second positioning post 122.

[0040] It should be noted that the first bottom wall is provided with a first positioning post 112 near the first support part 111, wherein there can be two first positioning posts 112, which are arranged diagonally. The second bottom wall is provided with a second positioning post 122 near the second support part 121, wherein there can be two second positioning posts 122, which are arranged diagonally.

[0041] It is particularly important to note that the dimensions of the first positioning post 112 and the second positioning post 122 are different; for example, the diameter of the first positioning post 112 is larger than the diameter of the second positioning post 122. Furthermore, the four positioning holes on the first circuit board 21 are respectively positioned close to the four through holes 212 of the first circuit board 21; in other words, the positioning holes and through holes 212 are configured in a one-to-one correspondence.

[0042] In practical applications, such as Figure 1 , Figure 2 and Figure 3 As shown, in order to improve the space utilization of the first circuit board 21, the first circuit board 21 has a first side and a second side opposite to each other, and at least one of the first side and the second side is provided with a memory chip 22.

[0043] It should be noted that the memory chips 22 are arranged in two rows on the first side, with each row including multiple memory chips 22, and the memory chips 22 are arranged in two rows on the second side, with each row including multiple memory chips 22. In this way, as many memory chips 22 as possible can be arranged in the limited space of the first circuit board 21.

[0044] In practical applications, such as Figure 1 , Figure 2 and Figure 3 As shown, in order to improve heat dissipation efficiency, the memory device of the blade server also includes a heat-conducting plate 4, which is sandwiched between the memory chip 22 and the first cover plate 11; the heat-conducting plate 4 is sandwiched between the memory chip 22 and the second cover plate 12.

[0045] Among them, the thermally conductive sheet 4 can be a thermally conductive silicone pad. A thermally conductive silicone pad is a thermally conductive filler material synthesized using silicone as a base material through a special process. It is mainly used as the heat transfer interface between electronic devices and heat sinks or product casings, completing the heat transfer between heat-generating and heat-dissipating components. Simultaneously, the thermally conductive silicone pad also serves as insulation, shock absorption, and sealing, meeting the design requirements for miniaturization and ultra-thinning of equipment.

[0046] Thermally conductive silicone pads possess a degree of flexibility, allowing them to conform well to the surfaces of power devices and heat sinks or machine housings, achieving optimal thermal conductivity and dissipation. They also offer excellent insulation properties, ensuring the safety of electronic equipment during use. Furthermore, their good compressibility and resilience allow for the even distribution of pressure and heat. The slightly tacky surface facilitates handling and installation while maintaining a tight fit to the surface of electronic devices. With a thermal conductivity ranging from 1.0 to 12.0 W / m·K, these pads effectively transfer heat and reduce the temperature of electronic equipment.

[0047] For example, memory chips 22 are mounted on both the first side and the second side of the first circuit board 21. Thus, the heat-conducting sheet 4 includes a first heat-conducting sheet 4 and a second heat-conducting sheet 4. The first heat-conducting sheet 4 is bonded between the memory chip 22 on the first side and the first bottom wall of the first cover plate 11, and the second heat-conducting sheet 4 is bonded between the memory chip 22 on the second side and the second bottom wall of the second cover plate 12.

[0048] In addition, such as Figure 1 As shown, the blade server of this embodiment includes: a connector 6, a second circuit board 5, and a memory device for the blade server. The housing 1 and the connector 6 are both mounted on the second circuit board 5, and the gold fingers are connected to the connector 6.

[0049] In practical applications, blade servers also include a casing, a pull-out device, etc. The casing includes an upper cover, a lower cover, a front cover, etc. The casing forms an installation space for accommodating the connector 6, the second circuit board 5, and the memory devices of the blade server.

[0050] It should be noted that the housing 1 can be laid flat on the second circuit board 5. At this time, the first cover plate 11 can contact the second circuit board 5. The housing 1 occupies a small area of ​​the second circuit board 5 in the length and width directions, which can improve the utilization rate of the second circuit board 5 and thus arrange more components. In addition, the housing 1 is also thinner in the height direction, which can meet the height requirements of the blade server.

[0051] Specifically, since the blade server includes the memory device of the blade server as described above, and the specific structure of the memory device of the blade server refers to the above embodiment, the blade server shown in this embodiment includes all the technical solutions of the above embodiments, and therefore has at least all the beneficial effects achieved by all the above technical solutions, which will not be repeated here.

[0052] In practical applications, such as Figure 2 Figure 3 Figure 4 Figure 2 As shown, the fastener 3 is provided with a second threaded hole 31, and the second circuit board 5 is provided with a connector, which is threadedly connected to the second threaded hole 31. The first threaded hole 1111 and the second threaded hole 31 can be fine-pitch threads, and the connector can be a screw.

[0053] It should be noted that the second threaded hole 31 is provided with an internal thread, and the external and internal threads on the fastener 3 are integrated in a coaxial structure. This structure can be used to fasten the first cover plate 11, the first circuit board 21, and the second cover plate 12, and can also be used to mount the housing 1 onto the second circuit board 5. In addition, the structure in which the housing 1 is laid flat on the second circuit board 5 and fastened at four points has better shock resistance and a more stable mechanical structure.

[0054] The following describes the assembly process of the blade server. First, place the first circuit board 21 on top of the first cover plate 11. Then, place a thermally conductive silicone pad on one side of the sixteen memory chips 22 of the first circuit board 21. Flip the first circuit board 21 with the thermally conductive silicone pad attached. The first positioning post 112 on the first circuit board 21 is then assembled with the first positioning hole 211 on the first circuit board 21. At this point, the first circuit board 21 rests on the four first support parts 111 and is located within the area enclosed by the first sidewall. Then, place another thermally conductive silicone pad on the first... On the other side of the circuit board 21, the second cover plate 12 is then assembled with the second positioning hole 213 on the first circuit board 21 via the second positioning post 122. At this time, the two ends of the first circuit board 21 are clamped between the corresponding first support part 111 and second support part 121, and the first threaded hole 1111, through hole 212 and countersunk hole 1211 are coaxially arranged. Fasteners 3 are sequentially inserted into the countersunk hole 1211, through hole 212 and first threaded hole 1111 to complete the assembly of the blade server's memory device.

[0055] Furthermore, the gold fingers are inserted into the slots of the connector 6 in the horizontal direction of the second circuit board 5. At this time, the second threaded hole 31 of the fastener 3 is coaxially set with the fixing hole on the second circuit board 5. Then, a screw is passed through the fixing hole from the bottom of the second circuit board 5 and locked in the second threaded hole 31, thus realizing the installation of the blade server's memory device and the second circuit board 5.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
