Description

Technical Field

[0001] This utility model relates to the field of transformer cabinets, specifically a soundproof and heat-dissipating transformer cabinet. Background Technology

[0002] A transformer is a device that uses the principle of electromagnetic induction to change alternating current voltage. Its main components include a primary coil, a secondary coil, and an iron core. Transformers have multiple functions such as voltage transformation, current transformation, impedance transformation, isolation, and voltage stabilization, and are widely used in industry, agriculture, transportation, and urban communities. According to their application, they can be divided into several types, including power transformers, distribution transformers, and fully sealed transformers. In power systems, transformers are fundamental equipment for power transmission and distribution, playing a crucial role in the transmission, distribution, and use of electrical energy.

[0003] When current flows through the transformer windings, an alternating electromagnetic field is generated. This alternating electromagnetic field exerts a periodic electromagnetic force on the windings, causing them to vibrate and producing a humming sound. Some transformers are located near residential areas. To reduce the impact of transformer noise on surrounding residents, the transformers are housed in enclosures with sound insulation panels inside. However, these sound insulation panels are typically made of high-density, high-sound-absorbing materials such as foam plastics, fiber fabrics, polyester fibers, mineral wool, and fiberglass. These materials can affect the transformer's heat dissipation, posing a risk when the transformer operates under high load. Therefore, a sound-insulating and heat-dissipating transformer enclosure is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a soundproof and heat-dissipating transformer cabinet to solve the problem that soundproof panels affect the heat dissipation of transformers in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a soundproof and heat-dissipating transformer cabinet, comprising a cabinet body, a waterproof top fixedly installed on the upper end of the cabinet body, a sealed door at the front end of the cabinet body, soundproof panels fixedly installed on the inner walls of both the cabinet body and the sealed door, a heat dissipation mechanism on the cabinet body, the heat dissipation mechanism comprising an outer heat dissipation fin fixedly installed on the outside of the cabinet body and an inner heat dissipation fin fixedly installed on the inside of the cabinet body, both the outer and inner heat dissipation fins being hollow inside, parallel connectors fixedly installed at both ends of both the outer and inner heat dissipation fins, a connecting pipe between the outer and inner heat dissipation fins, and a driving mechanism inside the cabinet body.

[0006] Preferably, an outer frame is fixedly installed on the outer heat exchange fin, and an inner frame is fixedly installed on the inner heat exchange fin. Fan blades are rotatably installed in both the outer and inner frames.

[0007] Preferably, the cabinet body has holes, and the connecting pipe passes through the holes to the cabinet body.

[0008] Preferably, the outer heat exchange fins are fixed to the outer wall of the cabinet body by an external frame, the inner heat exchange fins are fixed to the inner wall of the cabinet body by an internal frame, one end of the connecting pipe is connected to the outer heat exchange fins, and the other end of the connecting pipe is connected to the inner heat exchange fins.

[0009] Preferably, the drive mechanism includes a drive motor fixedly installed inside the cabinet body and a circulating water pump connected to the connecting pipe. A drive shaft is fixedly installed on the fan blade. Helical gears are fixedly installed on the input ends of the drive shaft, drive shaft and circulating water pump, and the helical gears mesh together in pairs. A water pump base is provided on the circulating water pump.

[0010] Preferably, the water pump base is provided with bolts at the four corners, and the water pump base is fixed to the inside of the cabinet body by bolts.

[0011] Preferably, the circulating water pump is fixed to the cabinet body by a water pump base, and the output end of the drive motor is provided with a coupling, and the drive shaft is fixedly installed to the output end of the drive motor by the coupling.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The sound insulation panel in this application has the function of converting sound energy into heat energy or other forms of energy loss, effectively reducing noise propagation; the coolant circulates between the external and internal heat exchange fins, absorbing the heat of the cabinet body in the internal heat exchange fins, and then transferring it to the external heat exchange fins for heat dissipation, ensuring that the sound insulation performance is maintained while reducing the internal temperature of the cabinet body.

[0014] 2. In this application, the operation of the drive motor realizes the rotation of the drive shaft. This rotation causes the circulating water pump to operate, thereby making the coolant circulate between the inner and outer heat exchange fins. At the same time, the rotation of the drive shaft also drives the rotation of the transmission shaft, which in turn drives the rotation of the fan blades at both ends. The rotation of the fan blades acts on the airflow, causing it to flow through the inner and outer heat exchange fins at high speed, effectively improving the heat dissipation efficiency.

[0021] 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.

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides a technical solution for a soundproof and heat-dissipating transformer cabinet, including a cabinet body 2, a waterproof top 1 fixedly installed on the upper end of the cabinet body 2, a sealed door 3 at the front end of the cabinet body 2, soundproof panels 4 fixedly installed on the inner walls of both the cabinet body 2 and the sealed door 3, a heat dissipation mechanism 5 on the cabinet body 2, and a drive mechanism 6 inside the cabinet body 2. The soundproof panels 4 can convert noise energy into heat energy or other forms of energy loss, thereby reducing the propagation of noise. Furthermore, through the combined use of the heat dissipation mechanism 5 and the drive mechanism 6, the internal temperature of the cabinet body 2 can be reduced while ensuring sound insulation.

[0023] like Figure 2 , Figure 3 and Figure 4As shown, sound insulation panels 4 are fixedly installed on the inner walls of the cabinet body 2 and the sealed cabinet door 3. The heat dissipation mechanism 5 includes an outer heat dissipation fin 501 fixedly installed on the outside of the cabinet body 2 and an inner heat dissipation fin 502 fixedly installed on the inside of the cabinet body 2. The outer heat dissipation fin 501 and the inner heat dissipation fin 502 are hollow inside. Parallel connectors 506 are fixedly installed at both ends of the outer heat dissipation fin 501 and the inner heat dissipation fin 502. A connecting pipe 505 is provided between the outer heat dissipation fin 501 and the inner heat dissipation fin 502. An outer frame 503 is fixedly installed on the outer heat dissipation fin 501 and an inner frame 504 is fixedly installed on the inner heat dissipation fin 502. Fan blades 507 are rotatably installed inside the outer frame 503 and the inner frame 504.

[0024] Specifically, the design principle of the sound insulation panel 4 is based on effectively converting noise energy into heat energy or other forms of energy loss, thereby reducing noise propagation. The coolant can circulate between the outer heat exchange fins 501 and the inner heat exchange fins 502. When the coolant flows inside the inner heat exchange fins 502, it absorbs heat from the cabinet body 2, effectively reducing the internal temperature. Subsequently, when the heat-absorbing coolant transfers to the outer heat exchange fins 501, it dissipates the heat to the external environment, ensuring effective sound insulation while reducing the internal temperature of the cabinet body 2. This innovative cooling mechanism not only improves sound insulation but also ensures temperature control during equipment operation, thereby extending the equipment's lifespan and improving its operating efficiency.

[0025] like Figure 2 , Figure 3 and Figure 5 As shown, the drive mechanism 6 includes a drive motor 604 fixedly installed inside the cabinet body 2 and a circulating water pump 605 connected to the connecting pipe 505. A drive shaft 601 is fixedly installed on the fan blade 507. Helical gears 602 are fixedly installed on the input ends of the drive shaft 601, drive shaft 603 and circulating water pump 605, and the helical gears 602 mesh together in pairs. A water pump base 606 is provided on the circulating water pump 605. Bolts are provided at the four corners of the water pump base 606. The water pump base 606 is fixed to the inside of the cabinet body 2 by bolts.

[0026] Specifically, the operation of the drive motor 604 effectively drives the drive shaft 603 to rotate. When the drive shaft 603 starts to rotate, it not only drives the circulating water pump 605, but also causes the coolant to circulate between the outer heat exchange fins 501 and the inner heat exchange fins 502 of the system. Furthermore, the rotation of the drive shaft 603 also causes the transmission shaft 601 to rotate, which in turn drives the fan blades 507 connected to its two ends to rotate. During rotation, the fan blades 507 propel airflow at high speed across the outer heat exchange fins 501 and the inner heat exchange fins 502. This design greatly improves the heat dissipation efficiency of the entire system, ensuring temperature control during equipment operation.

[0027] Working principle: During use, the sound insulation panel 4 can convert noise energy into heat energy or other forms of energy loss, thereby reducing noise propagation. The drive motor 604 can drive the drive shaft 603 to rotate. After the drive shaft 603 rotates, it will drive the circulating water pump 605 to operate, so that the coolant circulates between the outer heat exchange fins 501 and the inner heat exchange fins 502. When the coolant is inside the inner heat exchange fins 502, it will absorb the heat inside the cabinet body 2. When the coolant that has absorbed the heat moves into the outer heat exchange fins 501, it will dissipate heat to the outside, thereby reducing the temperature inside the cabinet body 2 while ensuring sound insulation. When the drive shaft 603 rotates, it will also drive the transmission shaft 601 to rotate. When the transmission shaft 601 rotates, it will drive the fan blades 507 at both ends to rotate. When the fan blades 507 rotate, they will drive the airflow to flow at high speed through the outer heat exchange fins 501 and the inner heat exchange fins 502, further improving the heat dissipation effect.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
