The coil is sleeved on the iron core and located between the first insulating clamp and the second insulating clamp. The transformer proposed in this application, by fixing the iron core and coil with a detachable first insulating clamp, reduces the electrical insulation distance between the components and facilitates maintenance of the iron core and coil, resulting in a compact structure, high economy, and ease of maintenance.

[0004] The following problems were found in response to the above: When using a transformer to convert voltage levels, the traditional transformer has low cooling efficiency, resulting in unstable output voltage, which poses a significant safety hazard and is prone to fire, thereby reducing the service life of the traditional transformer. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where, when using transformers to convert voltage levels, traditional transformers have low cooling efficiency, leading to unstable output voltage, significant safety hazards, and a high risk of fire, thereby reducing the service life of traditional transformers. Therefore, this invention proposes a transformer heat dissipation self-regulating device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a transformer heat dissipation self-regulating device, comprising a chassis, a transformer fixedly connected inside the chassis, a plurality of insulating sleeves fixedly connected to the upper surface of the transformer, two ventilation openings on one side of the chassis, a heat dissipation device on one side of the chassis, the heat dissipation device comprising a base, one side of the base fixedly connected to the chassis, a blower, a heat exchanger and a battery fixedly connected to the upper surface of the base, an air outlet and an air inlet on the side of the chassis near the heat exchanger, an air inlet pipe fixedly connected to one end of the air inlet, the other end of the air inlet pipe fixedly connected to the blower, an air supply pipe fixedly connected to the other side of the blower, the other end of the air supply pipe fixedly connected to the heat exchanger, an air outlet pipe fixedly connected to the other end of the heat exchanger, the other end of the air outlet pipe fixedly connected to the air outlet, and an electrical wire fixedly connected inside the blower, the other end of the electrical wire fixedly connected to the battery.

[0007] The effect achieved by the above components is as follows: hot air is extracted from inside the blower casing, converted into cold air by a heat exchanger, and then sent back into the casing to cool the transformer.

[0008] Preferably, the arc surface of the air inlet pipe is fixedly connected to a bracket, and the lower surface of the bracket is fixedly connected to the base.

[0009] The effect achieved by the above components is to use the bracket to fix the air inlet pipe and prevent it from tipping over.

[0010] Preferably, an exhaust fan is fixedly connected inside the chassis, and the exhaust fan is located on one side of the air inlet.

[0011] The effect achieved by the above components is to use the exhaust fan to accelerate the drawing of hot air into the air intake duct.

[0012] Preferably, a fixing frame is fixedly connected inside the chassis, and a filter screen is slidably connected inside the fixing frame.

[0013] The effect achieved by the above components is to prevent large dust particles from the outside of the chassis from being brought into the chassis when the exhaust fan is drawing air.

[0014] Preferably, the side of the chassis away from the heat dissipation device is provided with a waterproof device. The waterproof device includes two fixing seats. One side of the fixing seat is fixedly connected to the chassis. A rotating shaft is rotatably connected inside the fixing seat. Baffles are fixedly connected to both ends of the rotating shaft. A waterproof cloth is fixedly connected to the arc surface of the rotating shaft. A hook is fixedly connected to one side of the waterproof cloth. Two flexible magnetic strips are fixedly connected to the other side of the waterproof cloth. Two magnetic strips are fixedly connected to one side of the chassis. A slot is opened on one side of the chassis.

[0015] The effect achieved by the above-mentioned components is to block the vents with waterproof cloth to prevent rainwater from entering.

[0016] Preferably, the arc surface of the rotating shaft is fitted with two springs, and the two ends of the springs are fixedly connected to the fixed seat and the baffle, respectively.

[0017] The effect achieved by the above components is: when the waterproof cloth is pulled down, a rotational force is applied to the spring, and when the waterproof cloth is retracted, the spring rebounds and pulls the waterproof cloth back.

[0018] Preferably, a handle is fixedly connected to one side of the waterproof cloth, and the handle has a "U" shaped cross-section.

[0019] The effect achieved by the above-mentioned components is to make it easy to pull down the waterproof cloth using the handle.

[0020] In summary, the beneficial effects of this utility model are as follows:

[0021] In this invention, when a heat dissipation device is needed to cool the transformer, the exhaust fan, blower, and heat exchanger are turned on. The exhaust fan draws hot air from outside the chassis and vents into the air inlet pipe. The filter screen inside the chassis can block most of the dust in the air to prevent damage to the transformer. When the filter screen is dirty and hinders airflow, it can be pulled out along the fixed frame for cleaning and then put back. The blower draws hot air into the air inlet pipe and sends it to the heat exchanger through the air outlet pipe. The hot air passes through the heat exchanger, which converts the hot air into cold air and sends it into the chassis through the air outlet pipe to cool the transformer. As the cold air enters the chassis, it sinks and the hot air rises. The hot air then passes through the exhaust fan into the air inlet pipe and is converted back into cold air by the heat exchanger and sent back into the chassis. This cycle continues to cool the transformer inside the chassis.

[0022] In this invention, when the transformer in the chassis is working outdoors and it is necessary to prevent rainwater from entering the chassis through the ventilation opening and damaging the transformer, a waterproof device is required. Pulling the handle will rotate the waterproof cloth that is retracted on the rotating shaft. The spring on the rotating shaft will twist as the waterproof cloth rotates out. After the waterproof cloth is rotated out, the hook is hooked into the slot to prevent the waterproof cloth from shrinking. Then, the flexible magnetic strip on the waterproof cloth is attracted to the magnetic strip on the chassis to keep the waterproof cloth tightly attached to the chassis to prevent rainwater from entering. After use, pull out the hook in the slot, separate the flexible magnetic strip from the magnetic strip, and slowly release upwards. The twisted spring will rebound and cause the waterproof cloth to slowly shrink and wrap back onto the rotating shaft. Attached Figure Description

A blower 402, a heat exchanger 403, and a battery 404 are fixedly connected to the upper surface of the base 401. The chassis 1 has an air outlet 410 and an air inlet 411 on the side near the heat exchanger 403. One end of the air inlet 411 is fixedly connected to an air inlet pipe 406, and the other end of the air inlet pipe 406 is fixedly connected to the blower 402. The other side of the blower 402 is fixedly connected to... An air duct 408 is fixedly connected at one end to a heat exchanger 403. An air outlet duct 409 is fixedly connected at the other end of the heat exchanger 403, and the other end of the air outlet duct 409 is fixedly connected to an air outlet 410. An electrical wire 405 is fixedly connected inside a blower 402, with the other end of the wire fixedly connected to a battery 404. Hot air is drawn from inside the blower 402 casing 1, converted into cold air by the heat exchanger 403, and then returned to the casing 1 to cool the transformer 2. A bracket 407 is fixedly connected to the arc surface of the air inlet duct 406. The lower surface of the bracket 407 is fixedly connected to the base 401, thus securing the air inlet duct 406 and preventing it from tipping over. An exhaust fan 412 is fixedly connected inside the casing 1, located to one side of the air inlet 411, thus accelerating the intake of hot air into the air inlet duct 406. The chassis 1 is fixedly connected to a mounting bracket 413, and a filter screen 414 is slidably connected inside the mounting bracket 413, which prevents large dust particles from the outside of the chassis 1 from being brought into the chassis 1 when the exhaust fan 412 is drawing air.

[0033] Reference Figure 5 and Figure 6 As shown in this embodiment: the waterproof device 5 includes two fixed seats 501. One side of the fixed seat 501 is fixedly connected to the housing 1. A rotating shaft 509 is rotatably connected inside the fixed seat 501. Baffles 502 are fixedly connected to both ends of the rotating shaft 509. A waterproof cloth 503 is fixedly connected to the arc surface of the rotating shaft 509. A hook 504 is fixedly connected to one side of the waterproof cloth 503. Two flexible magnetic strips 506 are fixedly connected to the other side of the waterproof cloth 503. Two magnetic strips 507 are fixedly connected to one side of the housing 1. A slot 508 is opened on one side of the housing 1, which achieves the effect of blocking the ventilation opening 6 with the waterproof cloth 503 to prevent rainwater from entering. Two springs 510 are sleeved on the arc surface of the rotating shaft 509. The two ends of the springs 510 are fixedly connected to the fixed seat 501 and the baffles 502 respectively. When the waterproof cloth 503 is pulled down, a rotational force is applied to the springs 510. When the waterproof cloth 503 is retracted, the springs 510 rebound and bring the waterproof cloth 503 back. A handle 505 is fixedly connected to one side of the waterproof cloth 503. The cross-section of the handle 505 is U-shaped, which makes it easy to pull down the waterproof cloth 503 using the handle 505.

[0034] Working principle: When cooling the transformer 2 requires the use of the heat dissipation device 4, the exhaust fan 412, blower 402, and heat exchanger 403 are turned on. The exhaust fan 412 draws hot air from outside the chassis 1 and vent 6 into the air inlet duct 406. The filter screen 414 inside the chassis 1 can block most of the dust in the air to prevent damage to the transformer 2. When the filter screen 414 is dirty and hinders airflow, it can be pulled out along the mounting bracket 413 for cleaning. After cleaning, it can be put back. The blower 402... 02 The hot air is drawn into the air inlet duct 406 and sent to the heat exchanger 403 through the air outlet duct 408. The hot air passes through the heat exchanger 403, which converts the hot air into cold air. The cold air is then sent into the chassis 1 through the air outlet duct 409 to cool the transformer 2. The cold air enters the chassis 1, sinks, and the hot air rises. The hot air then enters the air inlet duct 406 through the exhaust fan 412 and is converted into cold air by the heat exchanger 403 and sent back to the chassis 1. This cycle continues to cool the transformer inside the chassis 1.

[0035] In this utility model, when the transformer 2 in the chassis 1 is working outdoors and it is necessary to prevent rainwater from entering the chassis 1 through the ventilation vent 6 and damaging the transformer 2, a waterproof device 5 is required. Pulling the handle 505 will rotate the waterproof cloth 503 that is retracted on the rotating shaft 509 out. The spring 510 on the rotating shaft 509 will twist as the waterproof cloth 503 rotates out. After the waterproof cloth 503 that is retracted on the rotating shaft 509 rotates out, the hook 504 is hooked in the slot 508 to prevent the waterproof cloth 503 from shrinking. Then, the flexible magnetic strip 506 on the waterproof cloth 503 is attracted to the magnetic strip 507 on the chassis 1, so that the waterproof cloth 503 is tightly attached to the chassis 1 to prevent rainwater from entering. After use, pull out the hook 504 in the slot 508, separate the flexible magnetic strip 506 and the magnetic strip 507, and slowly release upwards. The twisted spring 510 rebounds and causes the waterproof cloth 503 to slowly shrink and wrap back around the rotating shaft 509.
