Description

Technical Field

[0001] This utility model relates to the field of electronic device housings, specifically to a cold plate for an SRIO switching interface board. Background Technology

[0002] SRIO is a next-generation high-speed interconnect technology based on packet switching, offering high reliability and performance for embedded system development. The SRIO switch interface board's cold plate is a key heat dissipation and enclosure component ensuring the stable operation of the SRIO high-speed switch interface board. It uses internally circulating coolant channels to quickly conduct and dissipate the high heat generated during board operation, and is widely used in high-density, high-power electronic devices. Internal threaded holes are provided for fastener connections, and it is widely used in electronic device heat dissipation and board packaging scenarios.

[0003] In existing technologies, the mounting posts containing internal threaded holes are generally designed to be too high, which can lead to several problems. For example, excessively high mounting posts occupy longitudinal mounting space on the board, limiting the integration density of the SRIO switching interface board and hindering the development of lightweight and miniaturized equipment. Secondly, excessively high mounting posts can easily lead to uneven stress distribution, resulting in poor adhesion between the cold plate and the substrate after assembly. This may cause a decrease in heat dissipation efficiency or structural loosening, making it difficult to meet the assembly and use requirements of high-performance electronic devices. Utility Model Content

[0004] The problem to be solved by this utility model is to provide a cold plate for an SRIO switching interface board.

[0005] To solve the above problems, this utility model provides a cold plate for an SRIO switching interface board. To achieve the above objectives, the technical solution adopted by this utility model to solve its technical problems is as follows: A cold plate for an SRIO switching interface board includes: a flat plate; a strip-shaped boss protruding from one side of the flat plate; an inner flow channel located inside the strip-shaped boss; a boss protruding from the top surface of the strip-shaped boss; and a protruding post protruding from one side of the flat plate. The strip-shaped boss and the protruding post are located on the same side of the flat plate, and the top of the protruding post has an internal threaded hole. Several protruding posts are distributed on both sides of the strip-shaped boss. The sidewall of the protruding post is integrally connected to the sidewall of the strip-shaped boss. An inner rounded corner is formed at the junction of the sidewall of the protruding post and the sidewall of the strip-shaped boss. The inner rounded corner gradually increases the cross-sectional area of ​​the connection between the protruding post and the strip-shaped boss along the extension direction from the protruding post to the strip-shaped boss. The top of the protruding post is higher than the top surface of the boss, and the sidewall of the boss does not contact the sidewall of the protruding post.

[0006] As a further improvement of this utility model, the axial length of the protruding post is no more than twice the thickness of the strip-shaped protrusion.

[0007] As a further improvement of this utility model, the sum of the axial length of the internal threaded hole and the thickness of the strip boss is less than the axial length of the protrusion.

[0008] As a further improvement of this utility model, the projection of all bosses along their own depth direction intersects with the inner flow channel.

[0009] As a further improvement of this utility model, the top surface of the boss is rectangular.

[0010] As a further improvement of this utility model, each end of the inner flow channel is vertically connected to an inlet and outlet hole, and the opening directions of the two inlet and outlet holes point to the same parallel direction.

[0011] As a further improvement of this utility model, the inlet and outlet holes are connected to the inner flow channel by passing through the first straight tube and the second straight tube in sequence, and the axes of the inlet and outlet holes, the first straight tube, and the second straight tube are all perpendicular to each other.

[0012] As a further improvement of this utility model, the inner flow channel is serpentine and contains at least two pairs of channel segments with opposite flow directions, and the sets of opposite channel segments are arranged alternately.

[0013] As a further improvement of this utility model, one side of the SRIO switching interface board cold plate has a flat surface, and the flat surface and the strip-shaped boss are respectively located on the front and back sides of the SRIO switching interface board cold plate.

[0014] As a further improvement of this utility model, the outer surface of the cold plate of the SRIO switching interface board is provided with a black anodized film.

[0015] The beneficial technical effects of using the SRIO switching interface board cold plate of this application are: The protruding post and the strip-shaped boss are integrally connected with an inner rounded corner at the junction, which gradually increases the cross-sectional area of ​​the connection. This effectively enhances the connection strength between the protruding post and the strip-shaped boss, while also dispersing stress concentration during assembly and use, reducing the risk of breakage or damage at the connection. It can effectively improve the bending resistance of the originally slender protruding post.

[0016] The top of the protruding column is higher than the top surface of the boss, and the side wall of the boss does not contact the protruding column. This ensures the stability of the protruding column as a fixed structure and avoids interference between the protruding column and the boss and the heating element, ensuring that the boss can fully contact the heating area to conduct heat.

[0017] The internally threaded hole at the top of the protrusion facilitates the fastening of other components with fasteners. Simultaneously, the protrusion does not negatively impact the internal flow channel. The flat section can be made relatively thin, thus saving material.

[0018] The arrangement of several protruding pillars on both sides of the strip-shaped boss, combined with the integrated connection structure, makes the cold plate more evenly stressed during assembly, which helps to improve the tightness of the cold plate and the substrate, reduce the problem of reduced heat dissipation efficiency or structural loosening caused by the gap in the bonding, and at the same time, the reasonable layout of the protruding pillars is also conducive to optimizing the utilization of the longitudinal installation space of the plate.

Several protruding posts 8 are distributed on both sides of the strip-shaped boss 3, and the sidewalls of the protruding posts 8 are integrally connected to the sidewalls of the strip-shaped boss 3. An inner rounded corner portion 10 is constructed at the junction of the sidewall of the protruding post 8 and the sidewall of the strip-shaped boss 3. Figure 6 As shown, the inner rounded corner portion 10 extends along the direction from the protruding post 8 to the strip-shaped boss 3, causing the cross-sectional area of ​​the connection between the protruding post 8 and the strip-shaped boss 3 to gradually increase. The height of the top of the protruding post 8 is higher than the height of the top surface of the boss 7, and the sidewall of the boss 7 does not contact the sidewall of the protruding post 8.

[0023] The inner rounded corner 10 is tangentially transitioned to the curved surface of the side wall of the convex pillar 8.

[0024] The beneficial effects of adopting the above technical solution are as follows: the protruding column 8 and the strip-shaped boss 3 are integrally connected, and the cross-sectional area of ​​the connection part gradually increases through the inner rounded corner 10, which effectively enhances the connection strength, disperses stress concentration, and improves the bending resistance of the protruding column 8. The top height of the protruding column 8 is higher than the top surface of the boss 7, and the side wall of the boss 7 does not contact the protruding column 8, which not only ensures the supporting stability of the protruding column 8 as a fixed structure, but also avoids interfering with the fit between the boss 7 and the heat-generating component, ensuring heat dissipation efficiency. The internal threaded hole 9 at the top of the protruding column 8 facilitates the fixing of other components, and the distribution of the protruding column 8 optimizes the utilization of longitudinal space.

[0025] In some other embodiments of this utility model, the axial length of the protrusion 8 is not greater than twice the thickness of the protrusion of the strip protrusion 3.

[0026] The beneficial effects of adopting the above technical solution are: it limits the excessive height of the protrusion 8, reduces the occupation of longitudinal installation space, facilitates the miniaturization and weight reduction of electronic equipment, and reduces the risk of uneven force caused by the excessive height of the protrusion 8.

[0027] In some other embodiments of this utility model, the sum of the axial length of the internal threaded hole 9 and the thickness of the protrusion of the strip boss 3 is less than the axial length of the protrusion 8.

[0028] The beneficial effects of adopting the above technical solution are: it ensures that the internal threaded hole 9 has sufficient depth to accommodate the fastener, while the protrusion 8 retains sufficient material thickness, which enhances the reliability of the threaded connection and the overall structural strength of the protrusion 8, and prevents the thread from stripping or the protrusion 8 from being damaged.

[0029] In some other embodiments of this invention, the projections of all bosses 7 along their own depth direction intersect with the inner flow channel 4.

[0030] The beneficial effects of adopting the above technical solution are: the boss 7 is located directly above the inner flow channel 4, which optimizes the heat conduction path and allows heat to be quickly transferred from the boss 7 to the coolant in the inner flow channel 4, significantly improving the cooling effect.

[0031] In some other embodiments of this utility model, the top surface of the boss 7 is rectangular.

[0032] The beneficial effects of adopting the above technical solution are: the top surface of the boss 7 is rectangular, which provides a large flat contact area, making it easy to fit tightly with the heat-generating component and enhancing the heat conduction performance. At the same time, the rectangular shape is easy to process and assemble, improving manufacturing efficiency and structural reliability.

[0033] In some other embodiments of this utility model, each end of the inner flow channel 4 is vertically connected to an inlet / outlet hole 1, and the opening directions of the two inlet / outlet holes 1 are in the same parallel direction.

[0034] The advantages of adopting the above technical solution are: it simplifies the connection layout of coolant pipelines, facilitates installation and maintenance, reduces the bending and complexity of external pipelines, reduces flow resistance, and improves system integration.

[0035] like Figure 3 , Figure 4 As shown, in some other embodiments of this utility model, the inlet / outlet hole 1 is connected to the inner flow channel 4 by passing through the first straight tube 5 and the second straight tube 6 in sequence. The axes of the inlet / outlet hole 1, the first straight tube 5, and the second straight tube 6 are all perpendicular to each other.

[0036] The beneficial effects of adopting the above technical solution are: the axes of the three components are perpendicular to each other, which increases the flow path of the coolant and the heat exchange area, improves the heat dissipation efficiency, and enhances the structural compactness.

[0037] like Figure 2 As shown, in some other embodiments of this utility model, the inner flow channel 4 is a serpentine bend, and its interior contains at least two pairs of channel segments with opposite flow directions, and each set of reverse channel segments is arranged alternately.

[0038] The beneficial effects of adopting the above technical solution are: it extends the coolant flow path and residence time, thereby improving heat exchange efficiency. Reverse flow enhances heat transfer and ensures uniform heat dissipation from the coolant.

[0039] like Figure 7 As shown, in some other embodiments of this utility model, one side of the SRIO switch interface board cold plate has a flat surface 2, and the flat surface 2 and the strip-shaped boss 3 are respectively located on the front and back sides of the SRIO switch interface board cold plate.

[0040] The beneficial effects of adopting the above technical solution are: the flat surface 2 and the strip protrusion 3 are located on opposite sides, and the flat surface 2 facilitates the close contact between the cold plate and the substrate or other components, ensuring structural stability and ease of installation.
