Description

Technical Field

[0001] This utility model belongs to the field of thermal management technology, and more specifically, it relates to a multi-channel heat dissipation mechanism for metal chassis cabinets. Background Technology

[0002] Multi-channel heat dissipation mechanisms in metal chassis cabinets are functional structures that achieve efficient heat dissipation by designing multiple independent or coordinated airflow paths. They are commonly used in scenarios with high heat dissipation requirements, such as servers and industrial control equipment. The core of multi-channel heat dissipation mechanisms in metal chassis cabinets lies in breaking the limitations of a single heat dissipation path through multi-channel design. By combining structural optimization and fluid mechanics principles, they solve the problem of local overheating during the operation of high-power equipment. However, the ventilation ducts of commonly used multi-channel heat dissipation mechanisms are fixed, resulting in low applicability to different heat dissipation locations inside different cabinets. Therefore, a new type of multi-channel heat dissipation mechanism for metal chassis cabinets is needed. Utility Model Content

Threaded rods are fixedly connected to the connecting rods B, and the threaded rods are engaged with the inner threads of the threaded tubes. A set of anti-slip pads A are respectively provided on the outer side of the two sets of top plates.

[0008] Furthermore, a ventilation plate is movably connected to the rear side of the outer shell. The ventilation plate has eighteen sets of ventilation slots, which are inclined. A set of shields is connected to the outer side of each of the eighteen sets of ventilation slots. A sealing ring A is provided on the inner side of the ventilation plate.

[0010] Furthermore, three sets of elastic clamps are connected to the rear side of the three sets of active boxes, and a set of anti-slip pads B are provided on the inner side of each of the three sets of elastic clamps.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. By setting anti-slip pads A, this utility model can help prevent the top plates from sliding due to vibration or external force by setting a set of anti-slip pads A on the outer side of the two sets of top plates, thereby improving the stability of the entire heat dissipation mechanism after installation.

[0023] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model. Example:

[0024] As attached Figure 1 To be continued Figure 6 As shown:

[0025] This utility model provides a multi-channel heat dissipation mechanism for a metal chassis cabinet, including a shell 1, a rotating component 3, and a movable box 4;

[0026] The outer casing 1 has a square hole, and three sets of positioning rods 8 are fixedly connected in the square hole. The upper and lower ends of the outer casing 1 each have a set of circular grooves on the left and right sides. Two sets of rotating parts 3 are respectively placed on the left and right sides of the outer casing 1, and a set of connecting rods A6 are fixedly connected to the upper and lower ends of the rotating parts 3. The connecting rods A6 are inserted into the circular grooves on the outer casing 1. A set of threaded tubes 7 are fixedly connected to the four sets of connecting rods A6. The threaded tubes 7 have threads inside. Three sets of movable boxes 4 are placed inside the outer casing 1, and a set of movable cover plates 17 are movably connected to the three sets of movable boxes 4. A set of ventilation pipes 20 are respectively provided on the left and right sides of the three sets of movable boxes 4, and a set of exhaust fans are installed inside the ventilation pipes 20.

[0027] Among them, such as Figure 3 and Figure 4As shown, the upper and lower ends of the outer casing 1 are respectively provided with a set of top plates 2, and two sets of rotating tubes 11 are respectively provided on the inner side of the two sets of top plates 2. The rotating tubes 11 are connected to connecting rods B10, and the four sets of connecting rods B10 are respectively inserted into the interior of four sets of threaded tubes 7. Threaded rods 9 are fixedly connected to the connecting rods B10. The threaded rods 9 are engaged with the inner threads of the threaded tubes 7. The outer side of the two sets of top plates 2 is provided with a set of anti-slip pads A12. By rotating the two sets of rotating parts 3, the threaded tubes 7 drive the threaded rods 9 to move, so that the two sets of top plates 2 move in the up and down directions respectively, so that the two sets of top plates 2 are in close contact with the inner surfaces of the upper and lower ends of the cabinet. The anti-slip pads A12 are used to prevent the top plates 2 from sliding due to vibration or external force, thereby improving the stability of the entire heat dissipation mechanism after installation.

[0028] Among them, such as Figure 5 As shown, a ventilation plate 5 is movably connected to the rear side of the outer casing 1. The ventilation plate 5 has eighteen sets of ventilation slots, which are inclined. A set of shields 13 is connected to the outer side of each of the eighteen sets of ventilation slots. A sealing ring A16 is provided on the inner side of the ventilation plate 5. A movable frame 14 is installed inside the ventilation plate 5. A filter screen A15 is provided on the inner side of the movable frame 14. The inclined design of the ventilation slots can guide air to flow out of the chassis and cabinet at a certain angle. Compared with vertical ventilation slots, it can reduce the resistance of airflow and increase the airflow speed in the air duct, thereby enhancing the heat dissipation efficiency. The shields 13 can block larger dust and debris from entering the chassis directly through the ventilation slots, reducing the impact of dust accumulation on the heat dissipation components. The filter screen A15 on the inner side of the movable frame 14 can further filter fine dust particles in the air.

[0029] Among them, such as Figure 6 As shown, a sealing ring B19 is fitted on the inner side of each of the three sets of movable cover plates 17, and a filter screen B18 is installed inside each of the three sets of movable cover plates 17. When the movable cover plate 17 is closed, the sealing ring B19 can form a tight seal with the contact surface of the movable box 4, preventing dust, moisture, oil and other contaminants from entering the interior of the ventilation pipe 20. The filter screen B18 is installed inside the movable cover plate 17 and can be installed together with the movable cover plate 17 or removed separately. The filter screen can be cleaned or replaced without tools.

[0030] Among them, such as Figure 6As shown, three sets of elastic clamps 21 are connected to the rear of the three sets of movable boxes 4 respectively, and a set of anti-slip pads B22 is provided on the inner side of each of the three sets of elastic clamps 21. The three sets of elastic clamps 21 are respectively clamped on the three sets of positioning rods 8. The elastic clamps 21 achieve clamping with the positioning rods 8 by their own elastic deformation. The installation or removal of the movable box 4 can be completed without the need for screws, wrenches or other tools. Maintenance personnel can directly remove the movable box 4 from the positioning rods 8, saving maintenance time. The anti-slip pads B22 on the inner side of the elastic clamps 21 increase the friction to prevent the movable box 4 from sliding or shaking on the positioning rods 8, and it is also convenient to make flexible adjustments according to the needs of different heat dissipation positions inside the cabinet.

[0031] The specific usage and function of this embodiment are as follows:

[0032] like Figures 1 to 6 As shown, in this utility model, by rotating two sets of rotating parts 3, the threaded tube 7 drives the threaded rod 9 to move, so that the two sets of top plates 2 move in the up and down directions respectively, so that the two sets of top plates 2 are in close contact with the inner surfaces of the upper and lower ends of the cabinet. The anti-slip pad A12 is used to prevent the top plates 2 from sliding due to vibration or external force, thereby improving the stability of the entire heat dissipation mechanism after installation. The inclined design of the ventilation slot can guide air to flow into or out of the cabinet at a certain angle. Compared with the vertical ventilation slot, it can reduce the airflow resistance and increase the airflow speed in the duct, thereby enhancing the heat dissipation efficiency. The shield 13 can block larger dust and debris from entering the cabinet directly through the ventilation slot, reducing the impact of dust accumulation on the heat dissipation components. The filter screen A15 on the inner side of the movable frame 14 can further filter fine dust particles in the air. The elastic clamp 21 uses its own elastic deformation to achieve the locking with the positioning rod 8. The installation or removal of the movable box 4 can be completed without screws, wrenches or other tools. Maintenance personnel can directly remove the movable box 4 from the positioning rod 8, saving maintenance time.
