Description

Technical Field

[0001] This utility model relates to the field of heat dissipation in electrical equipment, and in particular to a heat dissipation and flow guiding structure for a load phase advancer. Background Technology

[0002] Phase advancers are industrial machines used in industrial enterprises to reduce reactive power losses caused by large and medium-sized motors. They are divided into static phase advancers and variable load phase advancers. Variable load phase advancers are devices used for local reactive power compensation of wound-rotor asynchronous motors in variable load applications in industries such as cement, chemical, and mining.

[0003] A load phase advancer is a reactive power compensation device used to improve the operating conditions of large and medium-sized wound-rotor asynchronous motors. It is widely used in industrial production. During operation, the power devices (such as thyristors and reactors) of the load phase advancer generate a large amount of heat. If the heat cannot be dissipated in time, the internal temperature of the equipment will rise sharply. Traditional load phase advancer heat dissipation structures have many shortcomings. They are often composed of many parts, and the connection between the parts is cumbersome. They often require the use of various tools for installation, such as using screws for tightening or welding. This greatly increases the installation difficulty. The installation method is not flexible enough and cannot adapt to different installation environments and equipment layouts, increasing the difficulty of installation and maintenance. To address these issues, we propose a load phase advancer heat dissipation and airflow guiding structure. Utility Model Content

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.

[0023] Please see Figures 1-5In this utility model, a heat dissipation and airflow guiding structure for a load phase advancer includes a connecting frame 1. A housing 2 is fixedly connected to the right side of the connecting frame 1. A heat sink 3 is fixedly installed on the outer surface of the housing 2. Two connecting components 4 are fixedly connected to the outer surface of the connecting frame 1. Each connecting component 4 includes a mounting cylinder 401 fixedly connected to the connecting frame 1. A fixing plate 402 is fixedly connected to the inner wall of each mounting cylinder 401. Two sliding columns 403 are fixedly connected to the outer surface of each fixing plate 402. A sliding connecting cylinder 404 is slidably connected to the outer surface of each sliding column 403. A transmission square column 408 is fixedly connected to the outer surface of each sliding connecting cylinder 404. A port plate 407 is fixedly connected to one end of each transmission square column 408. An mounting bracket is provided on the outside of each port plate 407. Each sliding cylinder 404 has a fixed upper surface with a movable screw 405, and each movable screw 405 has a fastening nut 406 on its outer surface. The inner wall of the connecting frame 1 is fixedly connected with a flow guide 7. The connecting frame 1 and the outer shell 2 provide support and protection for the whole. The heat sink 3 is responsible for heat dissipation. The connecting assembly 4 enables flexible installation. The flow guide 7 guides the flow of hot air. All parts work together to ensure the normal operation of the load phase advancer. According to the installation position, the fastening nut 406 is loosened, and the position of the sliding cylinder 404 on the sliding column 403 is adjusted by moving the screw 405, thereby adjusting the position of the port plate 407. The port plate 407 is fixed to the corresponding equipment using the mounting nail 6. After installation, the cooling fan 302 is started to dissipate the heat generated by the load phase advancer.

[0024] The upper surface of the mounting cylinder 401 has two slots 5, and each moving screw 405 is slidably connected to the slot 5. The slots 5 provide a moving channel for the moving screw 405, ensuring that the sliding cylinder 404 can move smoothly when adjusting its position. This allows users to adjust the position of the port plate 407 according to actual installation needs, improving installation flexibility. Multiple guide vanes 8 are fixedly connected to the inner wall of the outer shell 2, and multiple heat dissipation fin groups 10 are fixedly embedded on the outer surface of the outer shell 2. The guide vanes 8 change the flow direction of hot air in the outer shell 2, making it flow more orderly to the heat dissipation component 3, improving heat dissipation efficiency. The heat dissipation fin groups 10 increase the heat dissipation area of ​​the outer shell 2, accelerate heat dissipation, and reduce the equipment temperature.

[0025] Two side vents 12 are provided on the outer surface of the housing 2. A dust filter 13 is fixedly connected to the inner wall of each side vent 12. The side vents 12 increase airflow and improve heat dissipation efficiency. The dust filter 13 prevents dust from entering the interior of the housing 2, protecting the electronic components of the load phase advancer and preventing dust accumulation from affecting equipment performance. A guide louver 11 is fixedly connected to the outer surface of the housing 2. A sealing ring 9 is fixedly connected to the left side of the connecting frame 1. The guide louver 11 further optimizes the heat dissipation effect, and the sealing ring 9 strengthens the connection frame 1 and other equipment. The connection ensures a tight seal to prevent dust and other contaminants from entering and protects the internal components of the equipment. The heat dissipation component 3 includes a ventilation duct 301 fixedly embedded in the outer surface of the outer casing 2. A cooling fan 302 is fixedly installed on the inner wall of the ventilation duct 301, and a filter element 303 is fixedly installed on the outer surface of the ventilation duct 301. The ventilation duct 301 provides installation space for the cooling fan 302 and guides airflow. The cooling fan 302 generates forced airflow to accelerate heat dissipation. The filter element 303 filters impurities in the air to prevent them from entering the equipment and protects the cooling fan 302 and other components.

[0026] The working principle of this utility model is as follows:

[0027] When installing the load phase advancer heat dissipation and airflow guiding structure, loosen the fastening nut 406 according to the installation position, and adjust the position of the sliding cylinder 404 on the sliding column 403 by moving the screw 405. When the sliding cylinder 404 slides, it can slide along the port plate 407, thereby adjusting the position of the port plate 407. Tighten the fastening nut 406 again to fix the adjusted position. Use the mounting nail 6 to fix the port plate 407 to the corresponding equipment. After installation, the cooling fan 302 starts to exhaust the heat generated by the load phase advancer. Under the guidance of the airflow guide shroud 7 and the airflow guide blades 8, the hot air flows to the heat sink 3. The heat dissipation fin assembly 10 dissipates some of the heat into the surrounding air. At the same time, the cooling fan 302 starts to exhaust the hot air inside the outer casing 2. The filter element 303 filters out impurities in the air to prevent them from damaging the cooling fan 302.
