Technical Field
[0001] This utility model relates to the field of computer motherboard heat dissipation, and in particular to a computer motherboard with a layered heat dissipation airflow. Background Technology
[0002] As computer hardware performance continues to improve, the number of integrated electronic components such as chips and capacitors on the motherboard, as a core component, continues to increase, resulting in a significant increase in the heat generated during operation. Heat dissipation is the key to ensuring stable operation of the motherboard and extending its service life. Especially in scenarios such as high-performance computing and long-term continuous operation, heat dissipation efficiency directly affects the overall performance of the device.
[0003] There are two common traditional heat dissipation methods: air cooling and water cooling. Air cooling is widely used because of its advantages such as simple installation, low hardware cost, and strong compatibility.
[0004] However, traditional air cooling methods have some shortcomings in use. Traditional air cooling relies on a single fan and heatsink, which are usually fixed to the upper part of the computer motherboard, making it difficult to achieve layered heat dissipation. In addition, during installation, the lower part of the computer motherboard is often in contact with the inner wall of the case, which means that the heat generated at the bottom of the computer motherboard cannot be dissipated in time, resulting in poor heat dissipation efficiency.
[0005] To address this issue, a computer motherboard with a layered heat dissipation channel is proposed. Utility Model Content

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0035] Reference Figure 1 - Figure 3 The present invention provides an embodiment of a computer motherboard with a layered heat dissipation channel, comprising a motherboard body 1, which is a computer motherboard, a prior art technology, and can be implemented by those skilled in the art. The upper surface of the motherboard body 1 is provided with a heat dissipation component 2 for dissipating heat from the upper part of the motherboard body 1, and the lower part of the motherboard body 1 is provided with a mounting plate 4 for fixing the motherboard body 1 in a chassis. The mounting plate 4 is provided with a lifting component 3 for dissipating heat from the lower part of the motherboard body 1. Under the action of the heat dissipation component 2 and the lifting component 3, layered heat dissipation can be achieved.
[0036] Reference Figure 1 , Figure 3 , Figure 4 The lifting component 3 includes a handwheel 31. The outer wall of the handwheel 31 has anti-slip texture for easy gripping. A double-ended screw 32 is fixedly connected to the rear surface of the handwheel 31. The outer wall of the double-ended screw 32 has two sections of threads facing opposite directions. The thread helix angle of the threaded sections is less than ten degrees. When the double-ended screw 32 stops rotating, the threaded parts at the threaded sections of its outer wall are fixed. The double-ended screw 32 passes through and is rotatably connected to the front surface of the mounting plate 4. The mounting plate 4 provides support for the double-ended screw 32. A slider 33 is slidably connected to the inner wall of the bottom end of the mounting plate 4. Two sets of sliders 33 are provided, symmetrically arranged front and back, and evenly distributed at the two sections of threads facing opposite directions on the outer wall of the double-ended screw 32. Both ends of the slider 33 are fixedly connected to connecting rods 34 for connecting connecting blocks 35. The end of the connecting rod 34 away from the slider 33 is fixedly connected to a connecting block 35 for pushing the connecting plate 36. A hinge seat is installed on the upper surface of the connecting block 35, and the connecting plate 36 is hinged to the inner surface of the hinge seat.
[0037] Reference Figure 3 , Figure 5 , Figure 6An expansion plate 38 is fixedly connected to the lower surface of the motherboard body 1. A heat sink 37 is slidably connected through the lower surface of the expansion plate 38. Both the expansion plate 38 and the heat sink 37 are made of metal and have strong thermal conductivity. Multiple sets of heat sinks are provided and are equidistantly distributed in the left and right directions. A rubber ring 39 is fixedly connected to the rear surface of the handwheel 31. An annular groove 310 is provided on the front surface of the mounting plate 4. The rubber ring 39 and the annular groove 310 fit together. Threaded holes are provided at the four corners of the upper surface of the mounting plate 4 for installation in the chassis.
[0038] Reference Figure 1 , Figure 3 , Figure 4 The double-ended screw 32 passes through and is threadedly connected to the inner surface of the slider 33. The connecting block 35 passes through and is slidably connected to the upper surface of the mounting plate 4. The lower surface of the main body 1 is equipped with a hinge seat 2. Both hinge seat 1 and hinge seat 2 are existing technologies and can be implemented by those skilled in the art. The top of the connecting plate 36 is hinged to the inner surface of the hinge seat 2. The connecting plate 36 will swing as the connecting block 35 moves, thereby changing the distance between the mounting plate 4 and the main body 1. The openings of hinge seat 1 and hinge seat 2 are both front-to-back oriented, so the connecting plate 36 cannot swing left-to-right.
[0039] Reference Figure 3 , Figure 5 , Figure 6 The heat sink 37 is fixedly connected to the upper surface of the mounting plate 4, and the rubber ring 39 is inserted into the inner wall of the annular groove 310. The outer surface of the rubber ring 39 and the inner surface of the annular groove 310 are in contact, which can provide friction and prevent the handwheel 31 from being accidentally rotated due to external force.
[0040] Reference Figure 1 - Figure 2 The heat dissipation assembly 2 includes a cooling fan 21 for heat dissipation. The cooling fan 21 is existing technology and can be implemented by those skilled in the art. After the cooling fan 21 is installed, it has wires that are electrically connected to the motherboard body 1. The cooling fan 21 is installed on the upper surface of the motherboard body 1. Mounting holes 23 are provided at both the left and right ends of the upper and lower surfaces of the cooling fan 21. The mounting holes 23 penetrate the front surface of the cooling fan 21. A rotating shaft 24 is inserted into the inner wall of the mounting hole 23. The rotating shaft 24 is inserted from front to back and can be removed for easy disassembly and assembly. Compared with the traditional rotating shaft 24, which cannot be disassembled and replaced, it has greater flexibility. A fixing rod 25 is fixedly connected to the rear surface of the rotating shaft 24, and a mounting rod 26 is fixedly connected to the rear surface of the fixing rod 25. A heat dissipation fin 22 is provided at the rear end of the cooling fan 21. A slot 27 is provided at both the left and right ends of the heat dissipation fin 22. The mounting rod 26 and the slot 27 fit together.
[0041] Reference Figure 1 - Figure 2The rear end of the mounting hole 23 is set to be semi-circular. The rear surface of the rotating shaft 24 is in contact with the rear end of the inner surface of the mounting hole 23. The rotating shaft 24 can rotate around the rear end of the mounting hole 23. There are two sets of rotating shaft 24, fixing rod 25, and mounting rod 26. The two sets of rotating shaft 24, fixing rod 25, and mounting rod 26 are symmetrically distributed on the left and right sides with the center line of the cooling fan 21. There are two rotating shafts 24 and fixing rods 25 in each set. The two sets of rotating shafts 24 and fixing rods 25 are located on the upper and lower sides of each set of mounting rods 26. Driving the mounting rod 26 can drive the two rotating shafts 24 and fixing rods 25 to move at the same time. The mounting rod 26 is snapped into the inner wall of the slot 27. The adjacent surfaces of the two rotating shafts 24 in each set are in contact with the mounting hole 23.
[0042] Working principle: When installing the motherboard body 1, the distance between the motherboard body 1 and the mounting plate 4 can be adjusted according to the size of the space inside the chassis. During adjustment, the handwheel 31 is turned to drive the double-ended screw 32 to rotate synchronously, which in turn drives the two sets of sliders 33 to slide in opposite directions along the inner wall of the mounting plate 4. The sliders 33 drive the connecting block 35 to move through the connecting rod 34, causing the hinged connecting plate 36 to swing, thereby changing the distance between the motherboard body 1 and the mounting plate 4. After the distance between the motherboard body 1 and the mounting plate 4 is adjusted, the rotation is stopped. Since the rubber ring 39 is in contact with the annular groove 310, it can provide friction, thus preventing the handwheel 31 from being accidentally turned and causing the double-ended screw 32 to rotate, ensuring the distance is stable. Then, the mounting plate 4 is installed in the chassis using screws.
[0043] When the distance between the motherboard body 1 and the mounting plate 4 changes, the expansion plate 38 and the heat sink 37 will also expand or retract. When the fan inside the motherboard blows, it can blow away the heat transferred from the motherboard body 1 to the expansion plate 38 and the heat sink 37, thereby achieving heat dissipation for the lower part of the motherboard body 1.
[0044] When the cooling fan 21 on the upper surface of the motherboard body 1 is running, the airflow generated can blow away the heat transferred to the heat sink fins 22, thereby achieving heat dissipation of the upper part of the motherboard body 1 and realizing layered heat dissipation.
[0045] Furthermore, the cooling fan 21 and the heat dissipation fins 22 can be flexibly disassembled and assembled. By bending the mounting rod 26, it can be inserted into or removed from the slot 27 to achieve the disassembly and assembly of the cooling fan 21 and the heat dissipation fins 22. The mounting rod 26 can also be flexibly replaced. When the mounting rod 26 and the slot 27 are disassembled, the rotating shaft 24 can be moved forward and separated from the mounting hole 23 to achieve the disassembly of the mounting rod 26. This facilitates the replacement of deformed or damaged mounting rods 26 (the mounting rod 26 is made of metal, and during installation, including the initial installation, it is easy to deform due to bending, which will affect the stability of subsequent fixation. The flexibility of replacement improves practicality and convenience).
[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
