Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, and in particular to a multi-fan combined air-cooling heat dissipation device. Background Technology

[0002] A multi-fan combined air-cooling heat dissipation device is a heat exchange component that integrates multiple cooling fans, along with heat exchange fins, heat pipes, and heat spreaders, to achieve rapid heat transfer and dissipation through forced convection. The multiple fans are combined in parallel through a frame-type bracket and modular splicing structure, while airflow is guided by air duct guides to flow directionally across the surface of the heat-generating element or the heat dissipation carrier, reducing airflow turbulence and air leakage.

[0003] Multi-fan combined air-cooling heat dissipation devices are used in computer hardware, industrial control equipment and server racks. They have the advantages of flexible structure, strong adaptability and low maintenance cost, and can effectively meet the continuous heat dissipation needs of medium and high power equipment. However, during the fan vibration, disordered cables will continuously rub against the fan blades, the edge of the metal frame and the heat dissipation fins. Long-term use will cause the cable insulation layer to wear down, causing short circuit faults and making the fan stuck and stop rotating. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a multi-fan combined air-cooling heat dissipation device, which aims to improve the problem of fan jamming caused by short circuit faults due to disordered cable arrangement in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a multi-fan combined air-cooling heat dissipation device, comprising a housing, a clamping mechanism installed on the middle right side of the outer wall of the housing, the clamping mechanism being used to collect and organize connecting wires, a connecting mechanism installed on the rear end of the outer wall of the housing, the connecting mechanism being used to fix and connect fans; the clamping mechanism includes a hollow elongated block, the hollow elongated block being installed on the middle right side of the outer wall of the housing, an internally threaded circular groove being formed on the middle rear end of the outer wall of the hollow elongated block, an irregular groove being formed on the front end of the outer wall of the hollow elongated block, clamping blocks being slidably connected to the upper and lower ends of the middle inner wall of the irregular groove, a sliding groove being formed on the middle lower end of the outer wall of the clamping block, a spring being fixedly connected to the rear side of the upper end of the outer wall of the clamping block, and a driving component being installed on the middle right side of the outer wall of the housing.

[0006] As a further description of the above technical solution: The drive assembly includes a threaded rod, which is installed on the middle right side of the outer wall of the housing. A hollow circular block is slidably connected to the front end of the outer wall of the threaded rod, and a trapezoidal slider is fixedly connected to the front end of the outer wall of the hollow circular block.

[0007] As a further description of the above technical solution: The connecting mechanism includes a connecting frame, which is installed on the rear end of the outer wall of the housing. Threaded grooves are provided around the front end of the inner wall of the connecting frame. A screw is threadedly connected to the middle of the inner wall of the threaded groove, and a washer is threadedly connected to the front end of the outer wall of the screw.

[0008] As a further description of the above technical solution: The threaded rod is threaded to the internal threaded circular groove.

[0009] As a further description of the above technical solution: The outer wall of the housing is threaded with fixing screws around its front end.

[0010] As a further description of the above technical solution: A protective plate is fixedly connected to the front end of the outer wall of the shell.

[0011] As a further description of the above technical solution: A fan structure is installed on the inner wall of the housing.

[0012] As a further description of the above technical solution: The clamping block is slidably connected to the trapezoidal slider.

[0013] This utility model has the following beneficial effects: 1. In this utility model, rotating the threaded rod causes it to move horizontally through the internal threaded groove of the hollow long block. The propulsive force provided by the threaded rod is transmitted to the trapezoidal slider through the hollow block. The movement of the trapezoidal slider drives the movement of the two clamping blocks. The clamping blocks slide through irregular grooves. The trapezoidal slider is driven by a sliding groove fixed to the upper end of the clamping blocks, causing the two clamping blocks to move relative to each other. The spring force is used to store the cable. Rotating the threaded rod in the opposite direction can remove the cable, preventing short circuits caused by cable wear, which could lead to the fan jamming and stopping.

[0014] 2. In this utility model, the fan structures are placed into the corresponding positions of the connecting frame in a preset order, so that the fan structures fit tightly with the connecting frame. Then, screw one is rotated, and the meshing action between screw one and the threaded groove is used to fix the rear end of screw one to the threaded groove inside the connecting frame. As screw one is tightened, the washer gradually connects tightly with the fan structure, which prevents the fan structure from shifting in the connecting frame. Finally, the fixing and connection of multiple fan structures are achieved, ensuring stability. Attached Figure Description

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.

[0018] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of a multi-fan combined air-cooling heat dissipation device, including a housing 1. A clamping mechanism 2 is installed on the middle right side of the outer wall of the housing 1. The clamping mechanism 2 is used to collect and organize connecting wires. A connecting mechanism 3 is installed on the rear end of the outer wall of the housing 1. The connecting mechanism 3 is used to fix and connect fans. The clamping mechanism 2 includes a hollow elongated block 201, which is installed on the middle right side of the outer wall of the housing 1. An internally threaded circular groove 204 is opened at the middle rear end of the outer wall of the hollow elongated block 201. An irregular groove 205 is opened at the front end of the outer wall of the hollow elongated block 201. The upper and lower ends of the middle of the inner wall of the irregular groove 205 are slidably connected to... The clamping block 202 has a groove 206 at the lower middle of its outer wall. A spring 207 is fixedly connected to the rear side of the upper end of the outer wall of the clamping block 202. A drive assembly 203 is installed at the middle right side of the outer wall of the housing 1. The drive assembly 203 includes a threaded rod 2031. The threaded rod 2031 is installed at the middle right side of the outer wall of the housing 1. A hollow circular block 2032 is slidably connected to the front end of the outer wall of the threaded rod 2031. A trapezoidal slider 2033 is fixedly connected to the front end of the outer wall of the hollow circular block 2032. The threaded rod 2031 is threadedly connected to the internal threaded groove 204. The clamping block 202 is slidably connected to the trapezoidal slider 2033. Specifically, rotating the threaded rod 2031 causes it to move horizontally via the internal threaded groove 204 on the hollow block 201. The thrust provided by the threaded rod 2031 is transmitted to the trapezoidal slider 2033 through the hollow block 2032. The movement of the trapezoidal slider 2033 drives the movement of the two clamping blocks 202. The clamping blocks 202 slide through the irregular groove 205. The trapezoidal slider 2033 is driven by the sliding groove 206 fixed to the upper end of the clamping blocks 202, causing the two clamping blocks 202 to move relative to each other. Through the elastic force of the spring 207, the cable is then stored. Rotating the threaded rod 2031 in the opposite direction allows the cable to be removed.

[0019] Reference Figure 1 and Figure 5 The connecting mechanism 3 includes a connecting frame 301, which is installed on the rear end of the outer wall of the housing 1. Threaded grooves 303 are provided around the front end of the inner wall of the connecting frame 301. A screw 302 is threadedly connected to the middle of the inner wall of the threaded groove 303, and a washer 304 is threadedly connected to the front end of the outer wall of the screw 302. Specifically, the fan structures 5 are placed into the corresponding positions of the connecting frame 301 in a preset order, so that the fan structures 5 fit tightly with the connecting frame 301. Then, the screw 302 is rotated, and the meshing action between the screw 302 and the threaded groove 303 is used to fix the rear end of the screw 302 to the threaded groove 303 inside the connecting frame 301. As the screw 302 is tightened, the washer 304 gradually connects tightly with the fan structure 5, which prevents the fan structure 5 from shifting in the connecting frame 301. Finally, the fixing and connection of multiple fan structures 5 are achieved, ensuring stability.

[0020] Reference Figure 1 and Figure 2 The outer wall of the housing 1 is threaded with fixing screws 6 around the front end, the outer wall of the housing 1 is fixedly connected with a protective plate 4, and the inner wall of the housing 1 is equipped with a fan structure 5. Specifically, the housing 1 is made of ABS engineering plastic, which is lightweight and temperature resistant, and can stably support the internal components and protect them from external environmental interference. The fixing screws 6 are made of galvanized carbon steel, and the galvanized layer can improve the rust resistance and ensure the overall stable installation. The protective plate 4 is made of perforated metal plate, which can prevent foreign objects from entering the housing 1 while ensuring airflow. The fan blades of the fan structure 5 are made of ABS plastic, which is lightweight and has low wind resistance. The motor uses a copper core coil and an engineering plastic shell, which can efficiently output power to drive the fan blades to rotate. Through forced convection, heat transfer is achieved, providing the core power for the device's heat dissipation function.

[0021] Working principle: Rotating the threaded rod 2031 causes the threaded rod 2031 to move horizontally through the internal threaded groove 204 set in the hollow long block 201. The propulsive force provided by the threaded rod 2031 is transmitted to the trapezoidal slider 2033 through the hollow circular block 2032. The movement of the trapezoidal slider 2033 drives the movement of the two clamping blocks 202. The clamping blocks 202 slide through the irregular groove 205. The trapezoidal slider 2033 is transmitted through the sliding groove 206 fixed to the upper end of the clamping blocks 202, so that the two clamping blocks 202 move relative to each other. Through the elastic force of the spring 207, the cable is then stored. Rotating the threaded rod 2031 in the opposite direction can remove the cable. The fan structures 5 are placed into the corresponding positions of the connecting frame 301 in a preset order, so that the fan structures 5 and the connecting frame 301 fit tightly together. Then, the screw 302 is rotated, and the engagement between the screw 302 and the threaded groove 303 is used to fix the rear end of the screw 302 to the threaded groove 303 inside the connecting frame 301. As the screw 302 is tightened, the washer 304 gradually connects tightly to the fan structure 5, which prevents the fan structure 5 from shifting in the connecting frame 301. Finally, the fixing and connection of multiple fan structures 5 are achieved, ensuring stability.
