A heat dissipating device for a transformer

Abstract

This utility model discloses a heat dissipation device for a transformer, relating to the field of transformer technology. It includes a housing with a heat dissipation mechanism inside, extending to the outside of the housing. A bracket is fixedly installed at the bottom of the housing. This heat dissipation device dissipates heat from the inside of the housing using a cooling mechanism. The downward movement of a connecting rod causes gears to rotate, changing the guide plate from a vertical to an inclined position. Because the left and right rows of guide plates are staggered, it facilitates extending the time the cold air spends in the housing, improving the cooling effect. Furthermore, the downward movement of the connecting rod causes a lifting plate to move downwards. The bottom surface of the lifting plate has continuous wavy protrusions, allowing cold air to flow to the bottom of the lifting plate, effectively promoting heat dissipation from the top of the transformer, improving the heat dissipation effect, and reducing the surface temperature of the transformer body.

Description

Technical Field

[0001] This utility model relates to the field of transformer technology, specifically to a heat dissipation device for transformers. Background Technology

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, the secondary coil, and the iron core (magnetic core). Its main functions include voltage transformation, current transformation, impedance transformation, isolation, and voltage stabilization (magnetic saturation transformer).

[0003] A search of patent application number CN202120867376.8 reveals a heat dissipation device for transformers. This device, when the flow sensor detects low airflow, accumulates dust on the filter screen, obstructing airflow. A first cylinder pushes the filter screen to a horizontal position and fixes it in place. The first cylinder repeatedly strikes the filter screen to knock off the dust. When the flow sensor detects that the airflow has increased to a set value, the first cylinder stops operating, and a second cylinder restores the filter screen to its initial state. This ensures that the filter screen can effectively filter dust while maintaining airflow, thus ensuring good heat dissipation for the transformer. During the heat dissipation process, a cooling unit allows cold air to enter the casing and contact the transformer, providing cooling. However, the cold air stays inside the casing for a short time, resulting in poor heat dissipation.

[0004] Further searching patent application number CN202222639727.7 reveals that this utility model belongs to the field of transformer heat dissipation technology, specifically a transformer protection device with good heat dissipation effect. Firstly, the transformer can be suspended and installed through the setting of a support frame. The motor and the rotating rod can control the rotation of fan blade one. The support rod can rotate synchronously with the motor with the cooperation of the turntable, transmission wheel one, transmission wheel two and transmission belt, so that bevel gear one can drive bevel gear two supported by bearing and connecting rod to rotate synchronously. During the heat dissipation process, the refrigeration unit allows cold air to enter the outer casing and come into contact with the transformer, which can dissipate heat from the transformer. However, the cold air stays in the outer casing for a short time, which cannot prolong the time in the outer casing, resulting in poor heat dissipation effect. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a heat dissipation device for a transformer. It utilizes a cooling mechanism to dissipate heat from the interior of the casing. Furthermore, the downward movement of the connecting rod causes gears to rotate, changing the guide plate from a vertical to an inclined position. Because the left and right rows of guide plates are staggered, it facilitates extending the time the cold air spends within the casing, improving cooling efficiency. The downward movement of the connecting rod also causes a lifting plate to move downwards. The bottom surface of the lifting plate has continuous wavy protrusions, allowing cold air to extend to the bottom of the lifting plate and flow, effectively promoting heat dissipation from the top of the transformer, improving heat dissipation, and reducing the surface temperature of the transformer body. This solves the problem of insufficient heat dissipation due to the short time the cold air spends inside the casing.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a heat dissipation device for a transformer, including a housing, a heat dissipation mechanism is provided inside the housing, the heat dissipation mechanism extends to the outside of the housing, a bracket is fixedly provided at the bottom of the housing, and a pipe is provided at the top of the housing.

A conveying pipe is provided on the top of the blocking plate and is in contact with the pipeline. A refrigeration unit is provided at the bottom of the housing. A vertical pipe is provided on the top of the refrigeration unit.

[0008] Preferably, a one-way valve is provided on one side of the pipe, and the rotating rod is in contact with the outer casing.

[0009] Preferably, the transformer body is disposed inside the housing, and the refrigeration unit is fixedly connected to the bracket.

[0016] Beneficial effects

[0017] This invention provides a heat dissipation device for a transformer. Compared with the prior art, it has the following advantages:

[0018] 1. The heat dissipation device of this transformer uses a refrigeration unit to dissipate heat from the inside of the casing. The downward movement of the connecting rod causes the gear to rotate, changing the guide plate from a vertical to an inclined state. Because the left and right rows of guide plates are staggered, it is convenient to extend the time that the cold air stays in the casing, thereby improving the cooling effect. The downward movement of the connecting rod also causes the lifting plate to move downward. The bottom surface of the lifting plate has continuous wavy convexity, which allows the cold air to extend to the bottom of the lifting plate and flow, effectively promoting heat dissipation at the top of the transformer, improving the heat dissipation effect, and reducing the surface temperature of the transformer body.

[0019] 2. The heat dissipation device of the transformer can be aligned with the groove below by moving the crossbar. Subsequently, the screw at the crossbar is merged with the groove, which can prevent the guide plate from rotating and increase the stability of the guide plate. In addition, the gear rail is fixedly connected to the connecting rod. The movement of the connecting rod can make all the gears rotate, which improves the working efficiency.

[0025] 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.

[0026] Please see Figure 1-4 The present invention provides a technical solution: a heat dissipation device for a transformer, including a housing 1, a heat dissipation mechanism 2 is provided inside the housing 1, the heat dissipation mechanism 2 extends to the outside of the housing 1, a bracket 3 is fixedly provided at the bottom of the housing 1, and a pipe 4 is provided at the top of the housing 1.

[0027] The heat dissipation mechanism 2 includes a gear 201. A guide plate 202 is provided inside the outer casing 1. A rotating rod 203 is provided inside the top of the guide plate 202. The guide plate 202 is fixedly connected to the gear 201 through the rotating rod 203. A lifting plate 204 is provided inside the top of the outer casing 1. The bottom surface of the lifting plate 204 is a continuous wave protrusion. A hole 205 is provided on the middle surface of the lifting plate 204. A blocking plate 206 is provided inside the hole 205. A conveying pipe 207 is provided on the top of the blocking plate 206 and is in contact with the pipe 4. A refrigerator 208 is provided at the bottom of the outer casing 1. A vertical pipe 209 is provided on the top of the refrigerator 208.

[0028] A one-way valve is installed on one side of the pipe 4. The rotating rod 203 contacts the outer casing 1, which allows the gas in the outer casing 1 to be released and prevents external gas from entering the outer casing 1. The transformer body 5 is installed inside the outer casing 1, and the refrigerator 208 is fixedly connected to the bracket 3.

[0029] The top of the vertical pipe 209 is horizontally collinear with the bottom inner wall of the outer casing 1. There are two sets of guide plates 202, and each set of guide plates 202 consists of two rows. Because the left and right rows of guide plates 202 are staggered and the guide plates 202 are already in an inclined state, it is convenient to extend the time of the cold air in the outer casing 1 and improve the cooling effect.

[0030] A connecting rod 210 is provided on the back of the outer casing 1. The connecting rod 210 has a U-shaped cross-section and is in contact with the outer casing 1. There are multiple gears 201, and each gear 201 has a toothed rail 212 on one side, which meshes with the gear 201. Each connecting rod 210 has a moving rod 213 on its top. The connecting rod 210 is fixedly connected to the lifting plate 204 through the moving rod 213. One end of the moving rod 213 extends into the interior of the outer casing 1 and is in contact with the outer casing 1. The downward movement of the connecting rod 210 can cause the toothed rail 212 and the moving rod 213 to move downward simultaneously, improving work efficiency. The downward movement of the toothed rail 212, due to its meshing with the gear 201, causes the toothed rail 212 to rotate. The downward movement of the moving rod 213 pushes the lifting plate 204 downward.

[0031] Please see Figure 1-2 There are two connecting rods 210, and a crossbar 211 is provided between the two connecting rods 210. A mounting screw is provided on one side of the crossbar 211, and a groove 214 is provided on the back of the housing 1. The crossbar 211 can be aligned with the groove 214 below by moving. Subsequently, the screw at the crossbar 211 is merged with the groove 214, which can prevent the guide plate 202 from rotating and increase the stability of the guide plate 202.

[0032] During operation, the refrigeration unit 208 can be used to allow cold air to enter the vertical pipe 209 and be released through the vertical pipe 209, allowing the cold air to enter the outer casing 1. This allows the cold air to come into contact with the transformer body 5 inside the outer casing 1, thus cooling the transformer body 5. Gas flow is also facilitated through the top hole 205, allowing gas to enter the delivery pipe 207 and be released through the pipe 4. This prevents excessive gas buildup inside the outer casing 1. A one-way valve at pipe 4 allows gas to be released from the outer casing 1, preventing external gas from entering. If adjustment is needed, first adjust the horizontal bar 2... Remove the screw at position 11 to separate it from the outer casing 1. After separation, move the crossbar 211 downwards. Simultaneously, the connecting rod 210, which is fixedly connected to the crossbar 211, moves downwards, causing the gear rail 212 to move downwards. Since the gear rail 212 meshes with the gear 201, the downward movement of the gear rail 212 causes the gear 201 to rotate. Because the guide plate 202 is fixedly connected to the gear 201 via the rotating rod 203, the rotation of the gear 201 causes the guide plate 202 to rotate. Initially, the guide plate 202 is in a vertical state; the rotation of the guide plate 202 can change it to an inclined state, allowing the guide plate 202 to... 2. Separated from the corresponding inner wall of the outer casing 1 and the transformer body 5, because the left and right rows of guide plates 202 are staggered and are already in an inclined state, it is convenient to extend the time of the cold air in the outer casing 1 and improve the cooling effect. When the connecting rod 210 moves downward, the moving rod 213 fixedly connected to the connecting rod 210 moves downward at the same time. The moving rod 213 contacts the outer casing 1, which does not affect the downward movement of the moving rod 213. The downward movement of the moving rod 213 pushes the lower lifting plate 204 downward, which will cause the lifting plate 204 to contact the transformer body 5. The distance between them is reduced, allowing them to gradually approach the top of the transformer body 5. As the cold air moves upward, and the bottom surface of the lifting plate 204 has continuous wavy convexity, the cold air extends to the bottom of the lifting plate 204 for flow, which can effectively promote heat dissipation at the top of the transformer and improve the heat dissipation effect. The guide plate 202 is vertical or inclined, which is adjusted according to the internal conditions of the outer casing 1. If the internal temperature of the outer casing 1 is not high, but the guide plate 202 is inclined, it is easy to cause damage to the transformer body 5. The adjustment of the guide plate 202 can be changed according to the temperature of the transformer body 5.
