Description

Technical Field

[0001] The utility model belongs to the technical field of control cabinets, in particular to a modular marine control cabinet heat dissipation device. Background Art

[0002] A marine control cabinet is a device that assembles switchgear, measuring instruments, protective devices, and auxiliary equipment in an enclosed or semi-enclosed metal cabinet or on a screen according to electrical wiring requirements. A marine control cabinet is a crucial component of a ship's electrical system, responsible for the centralized control of a variety of electrical equipment on board. Marine control cabinets integrate a large number of electrical components, such as contactors, relays, and circuit breakers. These components generate significant heat during operation. If heat is not promptly dissipated, the internal temperature of the control cabinet will rise, affecting the performance and lifespan of the electrical components and even causing safety hazards such as fire. Ventilation holes are generally provided in the outer casing to ensure proper ventilation and heat dissipation within the control cabinet.

[0003] However, existing marine control cabinet heat dissipation devices are not designed with a modular structure, which makes it inconvenient to install them on different control cabinets. In addition, the maintenance and replacement of the heat dissipation devices often require disassembly of the entire control cabinet or a large number of related components, which makes the operation complicated and the maintenance cost high. In addition, existing marine control cabinet heat dissipation devices are generally installed inside the cabinet body, and the heat dissipation method is relatively simple, which to a certain extent limits the heat dissipation effect and increases the difficulty of installation and maintenance.

[0004] To this end, we provide a modular marine control cabinet heat dissipation device to solve the above problems. Summary of the Invention

[0028] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0029] Example 1

[0030] In order to solve the problems of low modularity of existing marine control cabinet heat dissipation devices, inconvenience in installation on different control cabinets, and the need to dismantle the entire control cabinet or a large number of related components for repair and replacement, which results in complicated operation and high maintenance costs, please refer to Figure 1-Figure 2 The present invention provides a modular marine control cabinet heat dissipation device comprising two symmetrically arranged fixing plates 1, one located at the lower end of each side of a control cabinet body 2. Stud bolts 101 are provided between the two fixing plates 1 for fastening the fixing plates 1 to the side of the control cabinet body 2. The device also includes a mounting bracket 3, which is mounted outside the control cabinet body 2 and hingedly connected to the fixing plates 1 at its lower end. Both sides of the mounting bracket 3 are provided with multiple sets of height-adjustable air-cooling heat dissipation components 4 for extracting heat from the control cabinet body 2. The entire heat dissipation device can be mounted outside the control cabinet body 2 via the fixing plates 1 and the mounting bracket 3. This device has a high degree of modularity and can accommodate the required number of air-cooling heat dissipation components 4 based on the specific components within the control cabinet body 2. The device also offers flexible adjustment and excellent heat dissipation capabilities. The rotatable mounting bracket 3 also facilitates maintenance and replacement.

[0031] like Figure 2 As shown, the mounting frame 3 includes two rotating seats 301, each hinged to a corresponding fixed plate 1. Two symmetrical columns 302 are fixed to the top of the rotating seats 301. The tops of the four columns 302 on the left and right sides of the control cabinet body 2 are fixed with a length-adjustable top plate 303. The fixed plates 1 on both sides of the rotating seats 301 are each provided with a limit block 102, and the limit block 102 near the front of the control cabinet body 2 is tilted to support the mounting frame 3 in the tilted state. The mounting frame 3 can be rotated outward and tilted, thereby moving the air-cooled heat dissipation component 4 thereon to the outside of the control cabinet body 2, thereby facilitating the maintenance and replacement of the air-cooled heat dissipation component 4. At the same time, the fixed plate 1 and the mounting frame 3 are also easy to install outside the control cabinet body 2, enhancing the modularity of the heat dissipation device and making it adaptable to the installation and use of different control cabinet bodies 2.

[0032] To increase the adaptability of mounting bracket 3 and adapt it to control cabinet bodies 2 of varying sizes, top plate 303 comprises an outer plate 303a and an inner plate 303b that retracts into the outer plate 303a. A knob is located on the top of outer plate 303a for locking inner plate 303b. The length of top plate 303 can be adjusted based on the width of control cabinet body 2. To adjust, loosen the knob on top of outer plate 303a, pull or push the two side columns 302 until the elastic pads 404 of cooling fan 401 contact the control cabinet body 2, and tighten the knob on top of outer plate 303a.

[0033] like Figure 2-Figure 5 As shown, the air-cooled heat dissipation assembly 4 includes a cooling fan 401 positioned between two columns 302 and slidably connected to the columns 302. A fastener 402 is rotatably provided at the end of the cooling fan 401 for locking the cooling fan 401 in its sliding motion. The columns 302 are provided with slots 302a that mate with the fasteners 402. The position of the cooling fan 401 on the columns 302 can be adjusted based on the installation positions of components within the control cabinet body 2. Positioning the cooling fan 401 to the side of the components enhances the heat dissipation effect. To adjust the position, loosen the fasteners 402, allowing the cooling fan 401 to slide freely along the columns 302, and the fasteners 402 to slide freely along the slots 302a. Once the fasteners 402 are in the desired position, tighten them again.

[0034] The side of the cooling fan 401 closest to the control cabinet body 2 is provided with an elastic pad 404 that abuts against the control cabinet body 2. The side of the cooling fan 401 facing away from the control cabinet body 2 is provided with an air outlet hood 403. A plurality of evenly spaced air cooling connectors 302c are provided on one of the uprights 302 at the top of the rotating base 301. An air outlet duct 302d is provided above the air cooling connectors 302c. The air outlet hood 403 is connected to the air cooling connectors 302c via a duct. Hot air within the control cabinet body 2 is drawn out by the cooling fan 401, then passes through the air outlet hood 403, the duct, and the air cooling connectors 302c into the hot air flow path of the uprights 302. Hot air from the multiple air-cooling heat dissipation components 4 is then discharged through the air outlet duct 302d into the surrounding environment or into a heat recovery device. The provision of multiple air cooling connectors 302c allows the cooling fan 401 to be used with multiple cooling fans 401, and also facilitates adjusting the duct connection position when the position of the cooling fan 401 changes.

[0035] Example 2

[0036] On the basis of the first embodiment, in order to further improve the heat dissipation effect of the heat dissipation device, as shown in FIG. Figure 2 、 Figure 4 、 Figure 6As shown, the air-cooled heat sink assembly 4 is provided with a water-cooled heat sink assembly 5 inserted into the control cabinet body 2 through the heat dissipation holes on the side thereof. The left and right sets of water-cooled heat sink assemblies 5 are fixedly connected. The water-cooled heat sink assembly 5 is integrated with the air-cooled heat sink assembly 4, so its position can be adjusted along with the air-cooled heat sink assembly 4.

[0037] The water-cooling heat dissipation component 5 includes a plurality of water-cooling pipes 501 distributed at equal intervals on the top of the cooling fan 401, and a connecting pipe 502 is provided at the end of the water-cooling pipe 501 for connecting the relative water-cooling pipe 501. A plurality of water-cooling joints 302b distributed at equal intervals are provided on another column 302 on the top of the rotating seat 301, and an inlet and outlet water pipe is provided below the water-cooling joint 302b. The cooling fan 401 is connected to the water-cooling joint 302b through a pipe, and a flow channel for water flow is provided in the column 302 and the cooling fan 401; the water-cooling heat dissipation component 5 also includes a water-cooling box 503 located at the bottom of the control cabinet body 2, and the inlet and outlet of the water-cooling box 503 are respectively connected to the inlet and outlet water pipes at the lower end of the corresponding column 302 through pipes. The water-cooling pipe 501 is installed to the position where the components inside the control cabinet body 2 need to dissipate heat. The heat emitted by the components is conducted to the water body in the water-cooling pipe 501. After the water flows through the flow channel inside the cooling fan 401, it enters the water-cooling joint 302b through the pipe. The hot water of multiple water-cooling heat dissipation components 5 is collected in the internal flow channel of the column 302, and then introduced into the water-cooling box 503 through the pipe. After cooling in the water-cooling box 503, the cold water is pumped into the column 302 on the other side by the pump again, and then distributed to each water-cooling pipe 501, and heat is conducted again to complete the water cooling cycle; the setting of multiple water-cooling joints 302b makes it possible to adapt to the use of multiple water-cooling heat dissipation components 5, and when the position of the water-cooling heat dissipation component 5 changes, the access position of the pipe can also be conveniently adjusted.

[0038] To facilitate securing the water-cooling pipe 501 near the components, the water-cooling pipe 501 is a flexible tube with multiple equally spaced metal fins 501a on its surface, as well as grooves 501b for securing the water-cooling pipe 501 to the control cabinet body 2. The metal fins 501a significantly enhance heat conduction, while the grooves 501b can be used for securing with binding tape or pipe clamps.

[0039] The above-described embodiment merely represents one embodiment of the present invention. While the description is relatively specific and detailed, it should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements are all within the scope of protection of the present invention.
