Description

Technical Field

[0001] The utility model relates to the technical field of transformer heat dissipation, and more specifically, it relates to a transformer structure with a heat dissipation device. Background Art

[0002] In the existing transformer heat dissipation technology, the design of the heat dissipation device directly affects the operation efficiency and service life of the transformer. During the operation of the transformer, a large amount of heat is generated. If these heats cannot be effectively dissipated, it will cause the temperature of the transformer to rise, which will further affect the electrical performance and stability of the transformer, and may even cause damage to the transformer, resulting in faults and losses in the power system.

[0003] At present, some heat dissipation devices use heat exchange liquid and heat conduction pipes to help the transformer dissipate heat. The heat exchange liquid circulates through the heat conduction pipes to take away the heat generated by the transformer. However, there are some problems in this heat dissipation method in practical applications. First of all, this method usually involves the connection between multiple pipes. In the existing technology, the connection and release processes of the pipes are often not fast and convenient enough, which makes the installation and maintenance of the heat dissipation system more complex and time-consuming, increasing the labor cost and the risk of system failures.

[0004] In addition, the structural design of the pipe joints in the existing technology is often relatively simple, which may lead to poor sealing effects at the joints. Leakage is likely to occur at the poorly sealed joints, which will not only reduce the efficiency of the heat dissipation system, but also may cause environmental pollution and even safety accidents such as fires. Therefore, these deficiencies in the existing technology have an adverse impact on the safe operation and heat dissipation efficiency of the transformer. Summary of the Utility Model

[0036] More specifically, when the temperature of the transformer 1 is too high, the cooler 23 is turned on. The heat exchange liquid is conveyed from the cooler 23 to the conveying tube 21 through an external conveying pump, and then conveyed to the corresponding heat conduction tube 20 through the conveying tube 21. Since the heat conduction tube 20 is in contact with the outer wall of the transformer 1, the heat exchange liquid can take away the heat on the outer surface of the transformer 1. The design of the plurality of fins 24 can increase the heat exchange area, thereby improving the heat exchange efficiency. Then, the heat exchange liquid carrying heat will enter the cooler 23 again through the conveying tube 21 connected to the output end of the guiding tube for cooling, so as to realize the recycling of the heat exchange liquid. Then, the heat exchange liquid cooled by the cooler 23 can be used again to dissipate heat from the transformer 1.

[0037] In summary, when the overall device is in use or running: when it is necessary to connect the delivery pipe 21 and the cooler 23, the matching sleeve 3 is rotated in the corresponding direction, and the matching sleeve 3 drives the return block 8 to move, so that the return block 8 and the fixed block 10 cooperate to squeeze the spring 9, and at the same time, the first guide block 11 connected to one side of the matching sleeve 3 slides along the second guide block 12. Due to the special structure of the first guide block 11 and the second guide block 12, when the matching sleeve 3 rotates, it will rise along the second guide block 12, and then the matching sleeve 3 The guide plate 5 and the guide groove 6 will drive the matching frame 15 to move in the clearance groove 17, and due to the special structural design of the guide groove 6 and the limitation of the side wall of the clearance groove 17 on the side wall of the matching frame 15, the matching frame 15 will gradually move outward, and at the same time, the movement of the matching sleeve 3 will push the push rod 13 set on one side to move, so that the push rod 13 compresses the push spring 14 set on the outer sleeve, and then the end of the delivery pipe 21 connected with the hard pipe 4 is inserted into the sleeve 2, and one end of the hard pipe 4 is pressed against the rubber sleeve 7, and then the matching is released. The sleeve 3, the spring 9 will reset and push the return block 8 to reset, so that the matching sleeve 3 rotates in the opposite direction, and then the matching sleeve 3 will drive the guide plate 5 and the guide groove 6 to reset, so that the matching frame 15 moves inward, and one end of the matching frame 15 will be fully inserted into the matching groove 16, and at this time the spring 9 has been fully reset, so that the matching sleeve 3 removes the limit of the first guide block 11 and the second guide block 12, and then the multiple push springs 14 will reset and push the push rod 13 to reset, and then the push rod 13 will push the matching sleeve 3 to reset.

[0038] When the temperature of the transformer 1 is too high, the cooler 23 is turned on, and the heat exchange liquid is transported from the cooler 23 to the delivery pipe 21 through an external delivery pump, and then transported to the corresponding heat conducting pipe 20 through the delivery pipe 21. Since the heat conducting pipe 20 is in contact with the outer wall of the transformer 1, the heat exchange liquid can take away the heat from the outer surface of the transformer 1. The design of multiple fins 24 can increase the heat exchange area, thereby improving the heat exchange efficiency. Then, the heat exchange liquid carrying the heat will enter the cooler 23 again through the delivery pipe 21 connected to the output end of the guide pipe for cooling, thereby realizing the recycling of the heat exchange liquid. Then, the heat exchange liquid cooled by the cooler 23 can be used again to dissipate heat from the transformer 1.
