[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The utility model provides Figures 1 to 5 A heat dissipation device and a soft starter shown in the figure include a U-shaped mounting frame 1, an air inlet is provided at the bottom of the U-shaped mounting frame 1, a fan assembly 2 is embedded in the inner cavity of the air inlet, the inner cavity of the U-shaped mounting frame 1 is rotatably connected to a rotating shaft through a bearing, a movable adjustment plate 3 is fixed to the outer side of the rotating shaft, a chamber 4 is protruded outwardly from the top of the inner side of the U-shaped mounting frame 1, one side of the movable adjustment plate 3 extends to the inside of the chamber 4 and fits with the inner wall of the chamber 4, a deflection assembly 5 for adjusting the angle of the movable adjustment plate 3 is provided in the inner cavity of the U-shaped mounting frame 1, and air outlets 6 are provided on both sides of the inner side of the U-shaped mounting frame 1;

[0027] The movable adjustment plate 3 is driven to swing inside the U-shaped mounting frame 1 and the chamber 4 through the deflection assembly 5, and the deflection angle is adjusted to guide the airflow sent in by the fan assembly 2, and most of the air is transported to one side. The airflow sent into the soft starter body 12 from different directions flows through various corners to form different airflow channels, so that the heat inside the soft starter body 12 is quickly discharged.

[0028] The deflection assembly 5 includes a servo motor 51 fixed to one side of the inner cavity of the U-shaped mounting frame 1, and a driving threaded rod 52 is fixed to the output shaft of the servo motor 51. One end of the driving threaded rod 52 away from the servo motor 51 is rotated to the other side of the inner cavity of the U-shaped mounting frame 1 through a bearing, and the outer thread of the driving threaded rod 52 is connected to a movable part 53, and a through groove 54 is opened on the movable adjustment plate 3. The movable part 53 is located in the through groove 54, and the two ends of the movable part 53 are located on both sides of the movable adjustment plate 3. The driving threaded rod 52 is driven to rotate by the servo motor 51, and then the driving threaded rod 52 drives the movable part 53 to translate in the U-shaped mounting frame 1, and the movable adjustment plate 3 is adjusted by the movable part 53, thereby adjusting the deflection angle of the movable adjustment plate 3, and guiding the airflow sent by the fan assembly 2, thereby forming two sets of airways in different directions.

[0029] The movable part 53 includes an internal threaded sleeve 531, and the driving threaded rod 52 threads through the inner cavity of the internal threaded sleeve 531. Fixed plates 532 are fixed at both ends of the internal threaded sleeve 531. The fixed plate 532 is attached to the inner wall of the U-shaped mounting frame 1. By setting the structure of the movable part 53 and threading the internal threaded sleeve 531 and the driving threaded rod 52, it can be ensured that the movable part 53 translates outside the driving threaded rod 52, and then the fixed plate 532 can support the internal threaded sleeve 531, and at the same time, the fixed plate 532 is used to drive the movable adjustment plate 3 to deflect and move.

[0030] The front and back sides of the inner cavity of the U-shaped installation frame 1 are provided with sliding grooves 7, and the inner cavity of the sliding groove 7 is slidably connected with a slider 8, and the opposite side of the slider 8 passes through the sliding groove 7 and is fixed to the outer side of the fixed plate 532. The slider 8 slides in the inner cavity of the sliding groove 7, which facilitates the limiting of the fixed plate 532 and ensures that the movable part 53 slides smoothly in the U-shaped installation frame 1. At the same time, it prevents the movable part 53 from rotating with the rotation of the driving threaded rod 52, resulting in the movable part 53 being unable to drive the outer side of the threaded rod 52 to translate.

[0031] A heat conducting block 9 is fixed to the inner side of the U-shaped mounting frame 1. The heat conducting block 9 penetrates the U-shaped mounting frame 1 and extends outward. Through the arrangement of the heat conducting block 9, it is convenient to directly utilize the heat conducting block 9 to contact the soft starter body 12, diffuse the heat on the outer shell surface of the soft starter body 12 outward, conduct heat through a variety of heat dissipation methods, and improve the cooling and heat dissipation efficiency.

[0032] The movable adjustment plate 3 is located above the fan assembly 2, and a protruding portion 10 for limiting the movable adjustment plate 3 is provided inside the U-shaped mounting frame 1. By limiting the position of the movable adjustment plate 3, it is ensured that after the movable adjustment plate 3 is deflected at an angle, the airflow delivered into the U-shaped mounting frame 1 through the fan assembly 2 is transported upward along one side, and then flows out from the air outlets 6 on both sides, forming different airways.

[0033] The outer side of the fixed plate 532 is provided with ventilation grooves 11, which are distributed on the fixed plate 532 in a staggered manner. By providing the ventilation grooves 11 on the movable part 53, the fixed plate 532 is prevented from blocking the air flow. The ventilation grooves 11 can allow the air flow to pass over the fixed plate 532 and continue to flow along the inside of the U-shaped installation frame 1, thereby maintaining the smoothness of the air flow.

[0034] Based on a heat dissipation device, a soft starter equipped with the heat dissipation device is also provided, including a soft starter body 12, the soft starter body 12 is located on the inner side of a U-shaped installation frame 1, and heat dissipation holes 13 are opened on both sides and the bottom of the soft starter body 12. By installing the U-shaped installation frame 1 on the outer side of the soft starter body 12, the airflow driven by the fan assembly 2 is introduced into the interior through the heat dissipation holes 13 on both sides of the soft starter body 12, and two air passages are alternately formed inside the soft starter body 12, so as to avoid the one-way air passage from being unable to completely exhaust the internal heat.

[0035] Installation angle brackets 14 are fixed on both sides of the top of the U-shaped installation frame 1, and installation screws 15 are movably arranged in the installation angle brackets 14. The installation screws 15 penetrate the installation angle brackets 14 and are threadedly connected with the outer side of the soft starter body 12. The installation angle brackets 14 fixed on the top of the U-shaped installation frame 1 fit the U-shaped installation frame 1, and the two are fixed by using the installation screws 15. A heat dissipation device is installed on the outer side of the soft starter body 12 to ensure that the heat generated inside the soft starter body 12 can be quickly discharged when the soft starter body 12 is working.

[0036] Positioning posts 16 are fixed on both sides of the bottom of the soft starter body 12, and positioning holes that are engaged with the positioning posts 16 are opened on the surface of the U-shaped mounting frame 1. The soft starter body 12 is limited by the positioning posts 16 and the positioning holes to ensure that the soft starter body 12 and the U-shaped mounting frame 1 remain stable.

[0037] During specific use, the U-shaped mounting frame 1 is mounted on the outside of the soft starter body 12, and then the fan assembly 2 is started. The fan assembly 2 is used to introduce external air into the U-shaped mounting frame 1 through the air inlet, and then the servo motor 51 drives the driving threaded rod 52 to rotate. The driving threaded rod 52 drives the movable member 53 to translate through the threaded relationship between the internal threaded sleeve 531 and the driving threaded rod 52. At the same time, the fixed plate 532 drives the movable adjustment plate 3 to deflect, so that the angle of the movable adjustment plate 3 is deflected, and the airflow sent by the fan assembly 2 is guided to one side. Then the airflow is transported upward along one side of the inner cavity of the U-shaped mounting frame 1, and then discharged from the air outlet 6, and enters from a single side of the soft starter body 12 through the heat dissipation hole 13 to form an airway inside. Then the servo motor 51 rotates in the opposite direction again to adjust the deflection angle of the movable adjustment plate 3 so that the airflow flows upward from the other side, and the direction in which the airflow enters the soft starter body 12 is adjusted to discharge the internal heat.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
