Description

Technical Field

[0001] This utility model relates to electrical equipment, specifically a dynamic voltage regulator with high-efficiency heat dissipation. Background Technology

[0002] Dynamic voltage regulators are common electrical devices used to stabilize AC power supplies. They generate significant heat during operation and require timely cooling; otherwise, the normal operation of the voltage regulator may be affected. Common cooling methods simply involve drawing in external air with a fan and then expelling it. This approach lacks structural optimization and is inefficient in terms of heat dissipation, resulting in insufficiently concentrated airflow. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a dynamic voltage regulator with high-efficiency heat dissipation, which can improve heat dissipation efficiency and improve airflow concentration.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency heat dissipation dynamic voltage regulator, comprising a housing, a switching unit installed in the housing, a voltage regulator unit installed in the housing, and a fan installed in the voltage regulator unit. The voltage regulator unit is connected to the switching unit to turn the output on and off via the switching unit. A window is provided at the bottom of the housing, and a vent is provided on the voltage regulator unit corresponding to the window position. A ventilation grille for air outlet is also provided on the side of the voltage regulator unit. A partition is provided inside the housing between the voltage regulator unit and the switching unit, and the switching unit is mounted on the partition. The housing is surrounded by the inner wall and the partition, and together with the window, forms a centralized ventilation channel. The fan is located at the vent position, and after starting, it creates a negative pressure in the centralized ventilation channel to draw external air into the voltage regulator unit. After heat exchange within the voltage regulator unit, the air is discharged through the ventilation grille.

[0005] As a further improvement of this utility model, the housing has a hollow structure at least at the position corresponding to the ventilation grille, and the two sides of the hollow structure are bent into the housing to form a limiting structure. The limiting structure is adapted to the edge of the voltage regulator unit to stabilize the voltage regulator unit.

[0006] As a further improvement of this utility model, the window is provided with a detachable outer frame and a filter screen installed on the outer frame. The outer frame is adapted to the size of the window and is bent on at least two sides to form connecting ears. The connecting ears are adapted to the corresponding window positions so that they can be inserted into the window and fastened to the housing by fasteners.

[0007] As a further improvement of this utility model, the bottom of the voltage regulator unit is provided with several wiring ports corresponding to the window position, and the voltage regulator unit is connected to or outputs power through the wiring ports.

[0008] As a further improvement of this utility model, the partition is provided with several through holes for wires to pass through and connect to the wiring port and the switch unit.

[0009] As a further improvement of this utility model, the position of the through hole is at least higher than that of the centralized ventilation channel.

[0010] The beneficial effects of this utility model are that by forming a centralized ventilation channel between the partition and the shell, the fan draws external air into the shell and conducts heat exchange in the voltage stabilizing unit before sending it out through the ventilation grille, which helps to improve heat dissipation efficiency, improve airflow concentration, and alleviate equipment instability caused by poor heat dissipation.

[0017] The present invention will now be described in further detail with reference to the embodiments shown in the accompanying drawings.

[0018] Reference Figure 1-5As shown, a high-efficiency heat dissipation dynamic voltage regulator includes a housing 1, a switching unit 2 installed in the housing 1, a voltage regulator 3 installed in the housing 1, and a fan 4 installed in the voltage regulator 3. The voltage regulator 3 is connected to the switching unit 2 to turn the output on and off through the switching unit 2. A window 11 is provided at the bottom of the housing 1, and a vent 31 is provided at the position of the voltage regulator 3 corresponding to the window 11. A ventilation grille 32 for air outlet is also provided on the side of the voltage regulator 3. A partition 5 is provided inside the housing 1 between the voltage regulator 3 and the switching unit 2, and the switching unit 2 is installed on the partition 5. The housing 1 is surrounded by the inner wall and the partition 5, and together with the window 11, a centralized ventilation channel 6 is formed. The fan 4 is located at the position of the vent 31, and after starting, it creates a negative pressure in the centralized ventilation channel 6 to attract external air into the voltage regulator 3. After heat exchange in the voltage regulator 3, the air is sent out through the ventilation grille 32.

[0019] After the fan 4 starts, external air is drawn into the housing 1. Because the partition 5 separates the voltage regulator unit 3 and the switching unit 2, the centralized ventilation channel 6 formed between the partition 5 and the inner wall of the housing 1 guides the airflow to flow centrally through the voltage regulator unit 3. After heat exchange within the voltage regulator unit 3, the air is exhausted through the ventilation grille 32. This structural design helps improve the concentration of airflow, making heat dissipation more efficient, thereby alleviating the performance degradation problem caused by the high temperature generated by the voltage regulator unit 3 during operation. The voltage regulator unit 3 can be connected to the housing 1 using fasteners such as bolts. The switching unit 2 can also be fixed inside the housing 1 by snap-fit ​​or bolt connection. The partition 5 can be integrally formed with the housing 1 or fixed by welding, bolt connection, etc. The fan 4 can be installed at the air inlet or outlet of the voltage regulator unit 3 and can be fixed to the voltage regulator unit 3 by bolt connection or snap-fit.

[0020] To further improve the stability of the voltage regulator unit 3 within the housing 1, in one optional embodiment, the housing 1 has a perforated structure 12 at least at the position corresponding to the ventilation grille 32, and the two side edges corresponding to the perforated structure 12 are bent inwards to form a limiting structure 121. The limiting structure 121 is adapted to the edge of the voltage regulator unit 3 to stabilize the voltage regulator unit 3.

[0021] By setting a perforated structure 12 at the position corresponding to the ventilation grille 32 on the housing 1, ventilation efficiency is improved. Simultaneously, the limiting structure 121 formed by bending the edges of the perforated structure 12 inwards into the housing 1 can fit and abut against the edge of the voltage stabilizing unit 3, thereby limiting the horizontal displacement of the voltage stabilizing unit 3, improving the installation stability of the voltage stabilizing unit 3, and reducing the risk of loosening due to equipment vibration. The perforated structure 12 can be integrally stamped with the housing 1, and the limiting structure 121 can be formed by a bending process.

[0022] Specifically, further optimization can be achieved by choosing the following method: a detachable outer frame 71 and a filter screen 72 installed on the outer frame 71 are provided at the position of the window 11. The outer frame 71 is adapted to the size of the window 11, and at least two sides are bent to form connecting ears 711. The connecting ears 711 are adapted to the corresponding positions of the window 11 so that after the window 11 is inserted, it is fastened to the housing 1 by fasteners.

[0023] By providing a detachable outer frame 71 and filter 72 at the window 11, the outer frame 71 is inserted into the window 11 via connecting ears 711 and secured to the housing 1 with fasteners. This facilitates the installation, removal, cleaning, and replacement of the filter 72, and also filters the air before it enters the housing 1, reducing dust and other impurities from entering the voltage regulator unit 3, thus improving heat dissipation and the equipment's operating environment. The outer frame 71 can be made of metal or plastic, and the connecting ears 711 can be integrally formed with the outer frame 71. The filter 72 can be fixed to the outer frame 71 by snap-fit, adhesive, or embedding. If both the outer frame 71 and the filter 72 are made of metal, they can also be connected by welding. Fasteners can be screws, bolts, or clips.

[0024] In some options, the bottom of the voltage regulator unit 3 is provided with several wiring ports 33 corresponding to the position of the window 11, and the voltage regulator unit 3 is connected to or outputs power through the wiring ports 33.

[0025] By setting a wiring port 33 at the bottom of the voltage regulator unit 3 corresponding to the window 11, it is convenient for external power lines or output lines to be connected to the voltage regulator unit 3 through the window 11. This reduces the length of the cable running inside the housing 1, helps to improve the neatness of the wiring, and also makes it easier for maintenance personnel to perform wiring operations.

[0026] Furthermore, the partition 5 is provided with several through holes 51 for wires to pass through and connect to the wiring port 33 and the switch unit 2.

[0027] By providing through holes 51 on the partition 5, the connecting wires between the switching unit 2 and the voltage regulating unit 3 can pass through the through holes 51 on the partition 5 to achieve electrical connection. This maintains the spatial isolation function of the partition 5 while realizing the circuit connection function, which helps to improve the rationality of wiring and space utilization. The number and position of the through holes 51 can be set according to the actual wiring requirements.

[0028] Furthermore, the position of the through-hole 51 is at least higher than that of the central ventilation channel 6. This arrangement avoids disrupting the airflow direction of the central ventilation channel 6.

[0029] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
