Description

Technical Field

[0001] The utility model relates to the field of liquid cooling plates, especially a simple fastener for a liquid cooling plate. Background Art

[0002] With the improvement of AIPC and server performance, the power consumption of chips (Central Processing Unit, abbreviated as CPU) is increasing continuously. The heat dissipation of chips is mainly solved by two methods: air cooling and liquid cooling. Compared with air cooling, liquid cooling has higher heat dissipation efficiency, is more energy-saving and environmentally friendly, and has a quieter working environment.

[0003] At present, there are two types of motherboard models: AMD motherboards and Intel motherboards. The sizes of AMD motherboards and Intel motherboards are different. Therefore, when the liquid cooling plate needs to be installed on the AMD motherboard or the Intel motherboard respectively, AMD brackets or Intel brackets are required, and the applicability is poor. Content of the Utility Model

[0004] To solve the above problems, the utility model provides a simple fastener for a liquid cooling plate.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows: The utility model relates to a simple fastener for a liquid cooling plate, which is applied to a motherboard and includes a liquid cooling plate and a fastening structure. A connecting frame is arranged on the liquid cooling plate, and fastening structures are arranged at both ends of the connecting frame. The liquid cooling plate is fastened on the chip of the motherboard through the fastening structure.

[0006] Preferably, the liquid cooling plate and the connecting frame are detachably connected.

[0007] Preferably, at least one positioning pin is arranged on the liquid cooling plate, and a positioning hole for fitting and installing with the positioning pin is arranged on the connecting frame. A fastener passes through the positioning hole to lock the connecting frame on the positioning pin.

[0008] Preferably, the motherboard is an AMD motherboard. The fastening structure includes a pair of AMD brackets and a pair of buckle heads arranged on the AMD motherboard. The pair of buckle heads are detachably connected to both ends of the connecting frame. The AMD brackets are provided with several protruding hooks, and the buckle heads are provided with buckle holes, and the buckle holes are matched with the protruding hooks of the AMD brackets, so as to fix the liquid cooling plate to the AMD brackets.

[0009] Preferably, the connecting frame is detachably connected to the buckle through a quick-release component. A pair of waist-shaped holes are provided on the connecting frame. The buckle includes a buckle arm and a connecting arm bent and formed from the buckle arm. A buckle hole is provided on the buckle arm, and a first connection hole is provided on the connecting arm. The quick-release component includes a column screw and a nut used in cooperation with the column screw. The column screw passes through the first connection hole and the waist-shaped hole in sequence and is locked and matched with the nut, so that the buckle is fixed on the connecting frame. In order to fix the buckle on the connecting frame, the diameter of the lower end of the column screw is larger than the inner diameter of the first connection hole, so that the buckle can be locked on the connecting frame after the column screw and the nut are matched.

[0010] Preferably, a guiding spring is provided inside the nut, and the guiding spring is sleeved on the column screw.

[0011] Preferably, mounting holes are provided at both ends of the AMD bracket, and the mounting holes are respectively adapted to the assembly holes reserved on the AMD motherboard. The mounting holes and the assembly holes are connected by fasteners, so that the AMD bracket is fixedly installed on the AMD motherboard.

[0012] Preferably, the motherboard is an Intel motherboard. The buckling structure includes an Intel backplane, a pair of Intel brackets, a pair of column screws, and a pair of nuts. A pair of waist-shaped holes are provided on the connecting frame. The Intel backplane is arranged on the back of the Intel motherboard.

The split structure reduces the machining time of the product. Coupled with the low-cost forming process of the bracket, the cost of the liquid cooling plate is effectively reduced. At the same time, in the present utility model, the connecting frame is pressed on the liquid cooling plate as a whole and the connecting frame and the liquid cooling plate are connected and fixed by screws or bolts. In this way, by increasing the force transmission cross-sectional area between the connecting frame and the liquid cooling plate (the force application point is the center of the chip), the overall stiffness of the liquid cooling plate and the buckling force between the liquid cooling plate and the chip are effectively improved. After the buckling structure is buckled on both sides, the connecting frame provides downward locking forces F1 and F2 to the liquid cooling plate from the middle and both sides respectively, improving the buckling force between the liquid cooling plate and the chip, thereby preventing poor contact between the liquid cooling plate and the chip.

[0036] Please refer to Figure 1-16 As shown, the utility model relates to a simple buckle for a liquid cooling plate, including a liquid cooling plate 2 and a buckling structure. The liquid cooling plate 2 is used to dissipate heat from the chip 6. A connection bracket 31 is provided on the liquid cooling plate 2. The connection bracket 31 is integrally formed by stamping a metal plate. A relief groove 313 is provided on the connection bracket 31. The two relief grooves 313 are arranged on both sides of the liquid cooling plate 2 to make it more convenient for the liquid cooling plate 2 to be positioned in the relief groove 313. Buckling structures are provided at both ends of the connection bracket 31. The liquid cooling plate 2 is buckled on the chip 6 through the buckling structure and is detachably connected to the main board 1. The bottom of the liquid cooling plate 2 is attached to the chip 6 to cool the chip 6. The main board 1 is an AMD main board or an Intel main board, and a chip 6 electrically connected to the main board 1 is inserted on the main board 1.

[0037] Further, the liquid cooling plate 2 and the connecting frame 31 are detachably connected. At least one positioning pin 21 is provided on the liquid cooling plate 2, and a positioning hole 311 that cooperates with the positioning pin 21 for installation is provided on the connecting frame 31. The positioning pin 21 and the positioning hole 311 are fixedly connected by a fastener. The fastener is a screw or a bolt, so that the connecting frame 31 is fixed on the liquid cooling plate 2. In this embodiment, there are four positioning pins 21, and four screws pass through the positioning holes 311 to fix the connecting frame 31 on the liquid cooling plate 2. Two, three, or four positioning pins 21 are all acceptable. By using four positioning pins 21, the connection between the liquid cooling plate 2 and the connecting frame 31 is more stable. The liquid cooling plate 2 and the connecting frame 31 adopt a split structure. The split structure reduces the machining time of the product. Coupled with the low-cost forming process of the bracket, the cost of the liquid cooling plate is effectively reduced. The connecting frame 31 is pressed entirely on the liquid cooling plate 2 and the connecting frame 31 and the liquid cooling plate 2 are connected and fixed with screws or bolts. In this way, by increasing the cross-sectional area of the force transmission between the connecting frame 31 and the liquid cooling plate 2, the overall stiffness of the liquid cooling plate 2 and the fastening force with the chip 6 are effectively improved. After the fastening structure is fastened on both sides, a downward locking force F1 is provided to the liquid cooling plate 2, and the connecting frame 31 provides a downward locking force F2 to the liquid cooling plate 2, improving the fastening force between the liquid cooling plate 2 and the chip 6, thereby preventing poor contact between the liquid cooling plate 2 and the chip 6.
