Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of radiator accessories, and particularly relates to an on-board radiator inside a server. Background Art
[0002] The motherboard radiator, also known as the CPU radiator, is an important component in computer hardware for reducing the temperature of the CPU. With the continuous improvement of CPU performance, its heat generation also increases. Therefore, the performance and efficiency of the motherboard radiator are crucial for ensuring the stable operation of the computer.
[0003] The main function of the motherboard radiator is to quickly dissipate the heat generated by the CPU into the air through the heat pipes, heat dissipation fins, fans and other structures inside it, thereby reducing the working temperature of the CPU and preventing problems such as performance degradation, system instability and even hardware damage caused by overheating.
[0004] With the continuous development of the 5G era, artificial intelligence, industrial Internet and cloud computing industries, the performance of servers has been continuously improved. After the on-board chips have been continuously iterated and updated, their chip power consumption has also been continuously increased. Consequently, the size of the radiator required to solve the corresponding heat dissipation requirements also needs to be increased. When the size of the motherboard remains unchanged within the limited space of the chassis, the increased size of the radiator occupies the layout space of other components. As a result, when arranging the components on the board, some components have to be placed under the radiator. For example, in this case, the radiator body and the bottom bracket are respectively arranged on the upper and lower sides of the motherboard to effectively utilize the space below the motherboard. Therefore, in the existing radiator design solutions, there is a risk of collision when the radiator is installed and tilts. At the same time, as the radiator increases, there are problems such as stress exceeding the standard and damaging the chip during the motherboard impact stress test or copper chips short-circuiting due to wear between the screw locking process and the motherboard in the existing locking solutions. Summary of the Utility Model
[0005] In order to solve the problems that the radiator in the prior art is prone to tilt during installation and the risk of collision is high due to the shaking of the radiator during the impact stress test, the utility model provides an on-board radiator inside a server.
[0006] The utility model is realized by the following technical solutions:
[0007] An on-board radiator inside a server includes a radiator body and a bottom bracket respectively arranged on the upper and lower sides of the motherboard. A plurality of screws penetrate through the radiator body. The screws include nuts and screw rods. A screw avoidance area is provided at the lower part of the screw rod, and a screw thread section is provided on the screw avoidance area; a compression spring is also sleeved on the screw rod, and two ends of the compression spring respectively abut against the nut and the radiator body; a hexagonal nut is arranged below the radiator body and is threadedly connected to the screw thread section; a locking threaded hole adapted to the screw thread section is provided on the bottom bracket.
[0008] By pre - installing the hexagonal nut on the threaded section of the screw passing through the lower part of the radiator body, the problem of component collision due to inclination when connecting the radiator body to the bottom bracket is avoided. After the radiator body and the bottom bracket are connected, the hexagonal nut is located between the main board and the radiator body, avoiding the problems of component collision and wear caused by the shaking of the radiator body during the impact stress test.
[0009] A further improvement of the present utility model is that the above - mentioned threaded section of the screw is arranged at the lower section of the screw avoidance area, and the threaded section of the screw protrudes from the surface of the screw avoidance area. This helps to reduce the processing difficulty.
[0010] A further improvement of the present utility model is that when the bottom surface of the above - mentioned radiator body contacts the heat - dissipating component on the main board, the upper and lower ends of the hexagonal nut are respectively abutted against the radiator body and the main board. When the main board is subjected to the impact stress test, the radiator body, the hexagonal nut, the main board and the bottom bracket can maintain a tightly - fitting state, preventing the wear problem caused by the fluctuation of the main board.
[0011] A further improvement of the present utility model is that the inner ring of the above - mentioned hexagonal nut is provided with a nut avoidance area, and the lower section of the nut avoidance area is provided with a nut threaded section, and the nut threaded section protrudes from the inner wall of the nut avoidance area. While reducing the processing difficulty, the assembly efficiency is improved.
[0012] A further improvement of the present utility model is that the diameter of the above - mentioned nut avoidance area is not less than the diameter of the screw part, forming an accommodation for the screw part.
[0013] A further improvement of the present utility model is that the height of the screw avoidance area above the above - mentioned threaded section of the screw is not less than the height of the nut avoidance area above the nut threaded section.
[0014] A further improvement of the present utility model is that after the threaded section of the screw and the locking threaded hole are installed in place, the stepped surface at the bottom of the screw is abutted against the inner bottom surface of the nut avoidance area.
[0015] A further improvement of the present utility model is that the four corners of the above - mentioned radiator body are provided with bosses, the screws penetrate through the bosses, and the lower end of the compression spring abuts against the top surface of the boss. The screws pass through the bosses at the four corners, improving the structural stability.
[0016] A further improvement of the present utility model is that the bottom surface of the above - mentioned boss is higher than the bottom surface of the radiator body.
[0017] A further improvement of the present utility model is that the lower part of the above - mentioned threaded section of the screw is also provided with a tapered part, which helps to form a guide for installation.
[0018] As can be seen from the above technical solution, the beneficial effects of the present utility model are as follows: By pre-installing the hexagonal nut on the screw thread section of the screw passing through the lower part of the radiator body, the problem of component collision caused by inclination when connecting the radiator body to the bottom bracket is avoided. After the radiator body and the bottom bracket are connected, the hexagonal nut is located between the main board and the radiator body, avoiding the problems of component collision and wear caused by the shaking of the radiator body during the impact stress test.

[0025] In order to make the purpose, features, and advantages of the present utility model more obvious and understandable, the technical solutions in the present utility model will be clearly and completely described below with reference to the drawings in the specific embodiments. Obviously, the embodiments described below are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments in this patent, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of this patent.
[0026] As shown in the appended Figure 1 and 4As shown in the figure, an on-board radiator inside a server includes a radiator body 1 and a bottom bracket 5 respectively arranged on the upper and lower sides of the main board 6; bosses 11 are provided at the four corners of the radiator body 1, and the bottom surface of the boss 11 is higher than the bottom surface of the radiator body 1; screws 2 penetrate through the bosses 11 at the four corners, improving the structural stability. A locking threaded hole 51 adapted to the threaded section 24 of the screw is provided on the bottom bracket 5. The locking threaded hole 51 protrudes from the top surface of the bottom bracket 5 to reduce the contact area between the bottom bracket 5 and the bottom surface of the main board 6, avoiding abrasion of the components on the bottom surface of the main board 6. Locking holes 61 allowing the screws 2 to pass through are provided on the main board 6.
[0027] As shown in the Figures 1-4 figure, the screw 2 includes a nut 21 and a screw rod 22, and a compression spring 4 is also sleeved on the screw rod 22. The two ends of the compression spring 4 are respectively abutted against the nut 21 and the boss 11. A tapered portion 25 is also provided at the lower part of the threaded section 24 of the screw. It helps to form a guide for installation.
[0028] As shown in the Figures 2-3 figure, a screw avoidance area 23 is provided at the lower part of the screw rod 22, and a threaded section 24 of the screw is provided on the screw avoidance area 23; the threaded section 24 of the screw is arranged at the lower section of the screw avoidance area 23, and the threaded section 24 of the screw protrudes from the surface of the screw avoidance area 23. It helps to reduce the processing difficulty. A hexagonal nut 3 threadedly connected to the threaded section 24 of the screw is provided below the radiator body 1; a nut avoidance area 31 is provided inside the inner ring of the hexagonal nut 3, and a nut threaded section 32 is provided at the lower section of the nut avoidance area 31, and the nut threaded section 32 protrudes from the inner wall of the nut avoidance area 31. While reducing the processing difficulty, the assembly efficiency is improved.
[0029] As shown in the Figures 1-4 figure, when the bottom surface of the radiator body 1 contacts the heat dissipation component on the main board 6, the upper and lower ends of the hexagonal nut 3 are respectively abutted against the radiator body 1 and the main board 6. When the main board 6 is subjected to an impact stress test, the radiator body 1, the hexagonal nut 3, the main board 6 and the bottom bracket 5 can maintain a tightly fitting state, preventing wear problems caused by the fluctuation of the main board 6. The diameter of the nut avoidance area 31 is not less than the diameter of a part of the screw rod 22. It forms an accommodation for a part of the screw rod 22. The height of the screw avoidance area 23 above the threaded section 24 of the screw is not less than the height of the nut avoidance area 31 above the nut threaded section 32. After the threaded section 24 of the screw and the locking threaded hole 51 are installed in place, the stepped surface at the bottom of the screw rod 22 abuts against the inner bottom surface of the nut avoidance area 31, and the nut threaded section 32 corresponds to the screw avoidance area 23; it helps to prevent the screw 2 from driving the hexagonal nut 3 to rotate together during the tightening rotation process, and can avoid abrasion of the main board 6 by the hexagonal nut 3.
[0030] In summary, the working principle of this device is as follows: By pre-installing the hexagonal nut 3 on the threaded section 24 of the screw, when the radiator body 1 is in contact with the heat dissipation element of the main board 6, the distance from the boss 11 to the locking hole 61 is filled with the hexagonal nut 3, which can prevent the radiator body 1 from tilting and scratching the main board 6 when the first screw 2 is connected to the bottom bracket 5; moreover, due to the placement of the hexagonal nut 3, it forms a support for the radiator body 1, preventing the radiator body 1 from wearing the main board 6 during vibration.
[0031] After the screw 2 is connected to the bottom bracket 5, the threaded section 24 of the screw is located in the locking threaded hole 51, and the nut threaded section 32 corresponds to the screw avoidance area 23. That is to say, at this time, rotating the screw 2 will not drive the rotation of the hexagonal nut 3, thus avoiding the random movement of the hexagonal nut 3 from scratching the main board 6.
[0032] For an on-board radiator inside a server according to the present utility model, by pre-installing the hexagonal nut 3 on the threaded section 24 of the screw passing through the lower part of the radiator body 1, it can avoid the problem of collision parts due to tilting when connecting the radiator body 1 to the bottom bracket 5. After the radiator body 1 is connected to the bottom bracket 5, the hexagonal nut 3 is located between the main board 6 and the radiator body 1, avoiding the problem of collision parts and wear caused by the shaking of the radiator body 1 during the impact stress test.
