AI Technical Summary
The heat dissipation effect of existing dry transformers is not good, mainly because the fan's blowing angle and airflow direction are fixed, so it cannot effectively blow to all parts of the transformer.
A dry transformer with a temperature-controlled heat dissipation structure is designed. By setting a cam and an extrusion rod in the spoiler mechanism, the spoiler constantly swings, and the spoiler drives the air to spoil, preventing the flow of the air flow in the fixed direction. At the same time, the dustproof net is knocked by the rubber block in the knocking mechanism to vibrate and prevent dust from adhering.
Through the design of the spoiler mechanism, the heat dissipation effect is improved, so that each part of the transformer can cool down more effectively; through the design of the knocking mechanism, the dustproof net is kept clean and prevented from affecting heat dissipation.

Description
Technical Field
[0001] The utility model relates to the technical field of transformers, in particular to a dry-type transformer with a temperature control and heat dissipation structure. Background Technique
[0002] A transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. The main components are the primary coil, secondary coil, and iron core (magnetic core). The main functions include: voltage transformation, current transformation, impedance transformation, isolation, voltage stabilization (magnetic saturation transformer), etc. A dry-type transformer is a type of transformer and is widely used in places such as local lighting, high-rise buildings, airports, docks, and CNC machinery equipment. Simply put, a dry-type transformer refers to a transformer in which the iron core and winding are not immersed in insulating oil.
[0003] During the use of a dry-type transformer, a certain amount of heat will be generated inside, and timely heat dissipation is required to prevent affecting the operation of the internal unit. The existing transformers generally have a cooling fan at the bottom, but the blowing angle of the fan does not change, so the direction of the air flow does not change, resulting in the air not being able to blow to all parts of the transformer, which may lead to poor cooling effect. In view of this, we need a dry-type transformer with a temperature control and heat dissipation structure. Content of the Utility Model
[0004] The purpose of the utility model is to provide a dry-type transformer with a temperature control and heat dissipation structure to solve the problems raised in the above background technique.

[0012] Preferably, a sleeve plate is fixedly sleeved on the outer wall of the round rod, and a rubber block is fixedly installed on the outer wall of the sleeve plate.
[0013] Compared with the prior art, the utility model provides a dry-type transformer with a temperature control and heat dissipation structure, which has the following beneficial effects:
[0014] 1. In the dry-type transformer with the temperature control and heat dissipation structure, the cam in the flow disturbing mechanism rotates clockwise to squeeze the outer wall of the extrusion rod, so that the spoiler can swing continuously to disturb the internal air, preventing the internal air flow from always flowing in one direction, resulting in some transformers above not being blown and cooled, and thus making the heat dissipation effect better.
[0015] 2. In the dry-type transformer with the temperature control and heat dissipation structure, the rubber block in the knocking mechanism continuously knocks the dust-proof net, enabling the dust-proof net to vibrate and shake off the dust on the outer wall to prevent dust adhesion.

[0021] As Figures 1 - 4As shown in the figure, the utility model provides a technical solution: a dry-type transformer with a temperature control and heat dissipation structure, including a base 1, on which a transformer 2 is fixedly installed. A dust-proof net 3 is provided on the side wall of the base 1, and a motor 4 is fixedly installed on the inner wall of the base 1. A driving rod 5 is fixedly connected to the output end of the motor 4, and a fan blade 6 is fixedly connected to the end of the driving rod 5. By starting the motor 4 to drive the fan blade 6 at the end of the driving rod 5 to rotate, the fan blade 6 can blow air on the transformer 2 above for heat dissipation. A flow disturbance mechanism 7 is arranged inside the base 1, and a knocking mechanism 8 is arranged on the flow disturbance mechanism 7.
[0022] In this embodiment, a flow disturbance mechanism 7 is arranged inside the base 1. By the cam 75 in the flow disturbance mechanism 7 rotating clockwise to squeeze the outer wall of the extrusion rod 74, the flow disturbance plate 72 can be made to swing continuously to disturb the internal air, preventing the internal air flow from always flowing in one direction, resulting in some of the transformers 2 above not being blown for cooling, and thus making the heat dissipation effect better.
[0023] In this embodiment, a knocking mechanism 8 is arranged on the flow disturbance mechanism 7. By the rubber block 84 in the knocking mechanism 8 continuously knocking on the dust-proof net 3, the dust-proof net 3 can be vibrated to shake off the dust on the outer wall to prevent dust adhesion. At the same time, through the setting of the reset torsion spring 82, the sleeve plate 83 can drive the rubber block 84 to rotate, preventing the rubber block 84 from over-squeezing the dust-proof net 3.
[0024] The above-mentioned flow disturbance mechanism 7 includes a rotating rod 71, which is rotatably connected to the inner wall of the base 1. A flow disturbance plate 72 is fixedly installed at the end of the rotating rod 71. A limiting torsion spring 73 is sleeved on the outer wall of the rotating rod 71. One end of the limiting torsion spring 73 is fixedly connected to the outer wall of the rotating rod 71, and the other end of the limiting torsion spring 73 is fixedly connected to the inner wall of the base 1. Through the elastic force of the limiting torsion spring 73, the rotating rod 71 can drive the flow disturbance plate 72 to rotate and reset, enabling the flow disturbance plate 72 to swing continuously to disturb the internal air, preventing the internal air flow from always flowing in one direction, resulting in some of the transformers 2 above not being blown for cooling. An extrusion rod 74 is fixedly installed on the outer wall of the rotating rod 71, and a cam 75 is fixedly sleeved on the outer wall of the driving rod 5. The cam 75 is located on the side of the extrusion rod 74. By driving the cam 75 on the outer wall to rotate clockwise to squeeze the outer wall of the extrusion rod 74, the extrusion rod 74 can drive the flow disturbance plate 72 at the end of the rotating rod 71 to rotate.
[0025] The above-mentioned knocking mechanism 8 includes a round rod 81, which is rotatably connected to the inner wall of the spoiler 72. A return torsion spring 82 is sleeved on the outer wall of the round rod 81. One end of the return torsion spring 82 is fixedly connected to the inner wall of the spoiler 72, and the other end of the return torsion spring 82 is fixedly connected to the outer wall of the round rod 81. The setting of the return torsion spring 82 enables the sleeve plate 83 to drive the rubber block 84 to rotate, preventing the rubber block 84 from excessively squeezing the dust-proof net 3. A sleeve plate 83 is fixedly sleeved on the outer wall of the round rod 81, and a rubber block 84 is fixedly installed on the outer wall of the sleeve plate 83. By continuously knocking the dust-proof net 3 with the rubber block 84, the dust-proof net 3 can be vibrated to shake off the dust on the outer wall and prevent dust from adhering.
[0026] In this embodiment, when the transformer 2 generates heat during operation, the motor 4 is started to drive the fan blade 6 at the end of the driving rod 5 to rotate, so that the fan blade 6 blows air to cool the transformer 2 above. At the same time, the cam 75 on the outer wall is driven by the driving rod 5 to rotate clockwise, so that the cam 75 continuously squeezes the outer wall of the extrusion rod 74, so that the extrusion rod 74 drives the spoiler 72 at the end of the rotating rod 71 to rotate. Then, the elastic force of the limit torsion spring 73 makes the rotating rod 71 drive the spoiler 72 to rotate and reset, so that the spoiler 72 continuously swings to disturb the internal air, preventing the internal air flow from always flowing in one direction, resulting in some transformers 2 above not being blown and cooled. At the same time, the spoiler 72 drives the rubber block 84 on the outer wall of the sleeve plate 83 to move towards the dust-proof net 3, so that the rubber block 84 continuously knocks the dust-proof net 3, so that the dust-proof net 3 vibrates to shake off the dust on the outer wall and prevent dust from adhering. At the same time, the setting of the return torsion spring 82 enables the sleeve plate 83 to drive the rubber block 84 to rotate, preventing the rubber block 84 from excessively squeezing the dust-proof net 3. Finally, the heat dissipation of the transformer 2 is completed.
[0027] The above has generally described the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, any modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
