Abstract
Description
Technical Field
[0001] This utility model relates to a heat dissipation box device, and more particularly to a wind-cooled heat dissipation box device for optical transmission equipment. Background Technology
[0002] An air-cooled heat sink for optical transmission equipment is a heat dissipation system specifically designed for optical transmission devices. It is commonly used in high-speed electronic equipment such as optical communication equipment, fiber optic modules, and laser equipment to ensure these devices can operate normally in high-temperature environments. The air-cooled heat sink primarily absorbs and removes heat generated by the equipment through air convection, maintaining the equipment's operating temperature within a safe range.
[0003] For example, application number CN202120788301.0 discloses an optical transmission equipment air-cooled heat dissipation box device. This device includes a main body, with a support leg fixedly connected to the lower surface of the main body. A fan is installed inside the main body, and a movable frame is movably connected to the outer surface of the fan. A limiting plate is fixedly connected to one end of the movable frame. A finger groove is formed on the outer surface of the limiting plate, and a sliding groove is formed on the inner surface of the main body. A slide rail is movably connected to the inner surface of the sliding groove. By setting the finger groove, limiting plate, movable frame, slide rail, and sliding groove, the problem of dust accumulation on the outer surface of the fan after prolonged use is solved. This is because the fan is placed inside the equipment, and excessive dust accumulation can affect the working efficiency of the heat dissipation box and generate significant noise.
[0004] Other existing technologies include CN201921102396.5, a wind-cooled heat dissipation box for optical transmission equipment.

[0006] However, the above-mentioned typical and existing technologies still have certain problems in use:
[0007] Traditional heat sinks typically use fixed heat dissipation mechanisms, resulting in poor heat dissipation on the sides of the equipment. Heat is difficult to dissipate quickly, which can easily lead to hot spots and affect the stable operation of the equipment. Utility Model Content

[0010] A fire extinguishing mechanism is provided on the rear side of the movable arm. The fire extinguishing mechanism includes a carbon dioxide fire extinguishing box, a smoke detector switch, a connecting pipe, and gas nozzles. The carbon dioxide fire extinguishing box is fixedly connected to the side of the movable arm.

[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] 1. This utility model, through its dynamic heat dissipation mechanism, enables the first motor to start and drive the threaded rod to rotate when the optical transmission device is working. The rotation of the threaded rod drives the threaded slider to move forward or backward along the threaded rod. During this process, the second motor drives the exhaust fan blades to rotate, dissipating heat through the exhaust fan blades. This allows the optical transmission device to dissipate heat and maintain its normal operating temperature. Furthermore, the dynamic heat dissipation mechanism allows the movable arm, along with the exhaust fan blades, to move, enabling heat dissipation at different locations on the optical transmission device body, thus preventing the sides of the optical transmission device body from being unable to receive effective heat dissipation.
[0018] 2. This utility model, through its fire extinguishing mechanism, features a carbon dioxide fire extinguishing box equipped with a smoke detector switch that can automatically detect smoke. Once smoke is detected, the smoke detector switch triggers the air pump to operate, rapidly spraying carbon dioxide gas to the fire scene through a connecting pipe, thus achieving automated fire extinguishing. Due to the electrical connection between the air pump and the smoke detector switch, the smoke detector switch can respond quickly once a fire occurs, starting the air pump and releasing carbon dioxide gas. The fire extinguishing process is fast and efficient, reducing the fire hazard of the optical transmission equipment. Attached Figure Description

[0024] 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.
[0025] Please see Figure 1-4 This utility model provides a technical solution for an air-cooled heat dissipation box for optical transmission equipment:
[0026] Example 1:
[0027] according to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a wind-cooled heat dissipation box for optical transmission equipment includes a heat dissipation box base 1. Heat dissipation side plates 2 are fixedly connected to both the left and right sides of the upper surface of the heat dissipation box base 1. A dynamic heat dissipation mechanism 4 is provided between the upper surfaces of the two heat dissipation side plates 2. The dynamic heat dissipation mechanism 4 includes side plate support arms 401, limiting plates 402, threaded rods 403, threaded sliders 404, movable arms 405, heat dissipation arms 406, and exhaust fan blades 407. Two side plate support arms 401 are provided, and their lower ends are fixedly connected to the upper surfaces of the two heat dissipation side plates 2 respectively. Limiting plates 402 are fixedly connected to both the front and rear sides of the upper surface of the side plate support arms 401. A threaded rod 403 is rotatably connected between the front and rear limiting plates 402. The threaded rod 403 has threads on its outer side. Two threaded sliders 404 are connected, and a movable arm 405 is fixedly connected between the two threaded sliders 404. A heat dissipation arm 406 is fixedly connected to the upper surface of the movable arm 405. A second motor 409 is provided on the upper surface of the heat dissipation arm 406. The output end of the second motor 409 is provided through the lower surface of the movable arm 405 and is connected to the exhaust fan blade 407. The exhaust fan blade 407 draws hot air from the top of the optical transmission device body 5, so that the optical transmission device dissipates heat and removes heat, maintaining the normal operating temperature of the device. A first motor 408 is provided on the outer side of the rear limiting plate 402. The output end of the first motor 408 is connected to the threaded rod 403. The lower end of the threaded slider 404 is slidably connected to the upper surface of the side plate support arm 401.
[0028] In practical use, the air-cooled heat dissipation box device of this utility model, when the optical transmission device is working, the first motor 408 starts and drives the threaded rod 403 to rotate. The rotation of the threaded rod 403 drives the threaded slider 404 to move forward or backward along the threaded rod 403. During this process, the second motor 409 drives the exhaust fan blade 407 to rotate, and the heat is discharged through the exhaust fan blade 407, so that the optical transmission device dissipates heat and removes heat, maintaining the normal operating temperature of the device. In addition, the dynamic heat dissipation mechanism 4 moves the movable arm 405 together with the exhaust fan blade 407, which can dissipate heat to different positions of the optical transmission device body 5, thereby avoiding the ineffective heat dissipation of the side positions of the optical transmission device body 5.
[0029] Example 2:
[0030] Based on Example 1, such as Figure 1 and Figure 2 As shown, a fire extinguishing mechanism 6 is provided on the rear side of the movable arm 405. The fire extinguishing mechanism 6 includes a carbon dioxide fire extinguishing box 601, a smoke detector switch 602, a connecting pipe 603, and gas nozzles 604. The carbon dioxide fire extinguishing box 601 is fixedly connected to the side of the movable arm 405. A connecting pipe 603 is provided on the side of the carbon dioxide fire extinguishing box 601 away from the movable arm 405. One end of the connecting pipe 603 is connected to the carbon dioxide fire extinguishing box 601, and an air pump is provided at the connection point. Multiple gas nozzles 604 are provided on the lower surface of the connecting pipe 603. A smoke detector switch 602 is provided on the outside of the carbon dioxide fire extinguishing box 601. The smoke detector switch 602 is specifically model FGR-700Z. The smoke detector switch 602 is electrically connected to the air pump. Multiple heat dissipation fins 3 are provided inside the left and right heat dissipation side plates 2. The multiple heat dissipation fins 3 are distributed equidistantly inside the heat dissipation side plates 2. The heat dissipation fins 3 are made of aluminum. A light transmission device body 5 is provided on the upper surface of the heat dissipation box base 1.
[0031] In practical use, the air-cooled heat dissipation box of the optical transmission equipment of this utility model is equipped with a smoke detector 602 in the carbon dioxide fire extinguishing box 601, which can automatically detect smoke. Once smoke is detected, the smoke detector 602 will trigger the air pump to work, and the carbon dioxide gas will be quickly sprayed to the fire scene through the connecting pipe 603 to realize automatic fire extinguishing. Since the air pump is electrically connected to the smoke detector 602, once a fire occurs, the smoke detector 602 can respond quickly, start the air pump, and release carbon dioxide gas. The fire extinguishing process is fast and efficient, reducing the fire hazard of the optical transmission equipment body 5.
