Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of plate radiators, and in particular relates to a novel plate radiator for transformers. Background Technology
[0002] A plate radiator for transformers is a cooling device used in oil-immersed power transformers, reactors, and other equipment. Its main function is to transfer the heat generated inside the transformer to the air through the heat sink, thereby controlling the temperature rise of the transformer and ensuring its normal operation. The working principle of the plate radiator is that the hot oil in the transformer tank enters the upper oil collection pipe of the radiator, flows through the heat sink, and then flows back to the transformer tank from the lower oil collection pipe. During this process, the hot oil transfers heat to the air.
[0003] In existing finned radiators, the oil inlet pipe is located at the end of the fin height. When the oil enters the internal chamber of the fin, it will naturally flow downwards due to gravity. The first area to come into contact with the fin area at the bottom of the oil inlet pipe is the fin area, resulting in a larger oil flow in these areas and a smaller oil flow in other areas. This leads to uneven oil distribution, making the fin prone to localized overheating and thus reducing heat dissipation efficiency. Utility Model Content

[0006] The oiling assembly includes an oil inlet pipe, a first oil outlet hole at the bottom of the oil inlet pipe, an oil inlet pipe connecting flange fixedly connected to the front end of the oil inlet pipe, a diversion pipe connected to the inner wall of the oil inlet pipe, and a plurality of second oil outlet holes on the surface of the diversion pipe.
[0007] The above technical solution allows for connection to external pipelines via an oil inlet pipe flange. Oil is introduced into the oil flow chamber through the first oil outlet on the oil inlet pipe, while the oil is dispersed through the branch pipes on both sides of the oil inlet pipe. Then, the oil is evenly distributed into the oil flow chamber through the second oil outlet on the branch pipe, avoiding localized overheating. This ensures that the oil is evenly in contact with the front and rear heat sinks, and the heat is dissipated into the air through the front and rear heat sinks, thereby improving heat dissipation efficiency and ensuring stable operation of the transformer in high-temperature environments.
[0008] As a further improvement to the above solution, an oil flow chamber is formed between the front heat sink and the rear heat sink, and the number of the front heat sink, the connecting plate and the rear heat sink are all provided in several.
[0009] The above technical solution stores hot oil in an oil flow chamber, ensuring that the hot oil comes into uniform contact with the front and rear heat sinks.
[0010] As a further improvement to the above solution, the surface of the oil inlet pipe is fixedly connected to the inner walls of the front and rear heat sinks.
[0011] As a further improvement to the above solution, the oil inlet pipe is connected to the oil flow chamber through the first oil outlet hole, and the surface of the diverter pipe is fixedly connected to the inner wall of the front heat sink and the rear heat sink.
[0012] The above technical solution connects the oil inlet pipe and the oil flow chamber through the first oil outlet hole, allowing hot oil to enter the interior of the oil flow chamber through the first oil outlet hole.
[0013] As a further improvement to the above scheme, the diversion pipe is connected to the oil flow chamber through the second oil outlet hole, and there are two diversion pipes, which are symmetrically distributed with the oil inlet pipe as the center.
[0014] The above technical solution uses two diversion pipes to distribute the hot oil, allowing it to contact the front and rear heat sinks evenly, thus avoiding localized overheating and improving heat dissipation.
[0015] As a further improvement to the above solution, the oil outlet assembly includes an oil outlet pipe, the front end of which is fixedly connected to an oil outlet pipe connecting flange, and the surface of the oil outlet pipe is provided with several oil holes.
[0016] The above technical solution allows for the connection between external pipelines and the oil outlet pipe via an oil outlet pipe connection flange.
[0017] As a further improvement to the above solution, the surface of the oil outlet pipe is fixedly connected to the inner wall of the front heat sink and the rear heat sink, and the oil outlet pipe is connected to the oil flow chamber through the oil hole.
[0018] The above technical solution allows oil from the oil flow chamber to enter the interior of the oil outlet pipe through the oil hole on the surface of the oil outlet pipe, and then the oil is discharged from the radiator.
[0019] Compared with the prior art, the beneficial effects of the present invention are:
[0020] This invention features an oil supply assembly. Specifically, oil enters the interior of the oil inlet pipe and is then introduced into the oil flow chamber through the first oil outlet on the inlet pipe. Simultaneously, the oil is dispersed through the branch pipes on both sides of the inlet pipe, and then evenly distributed into the oil flow chamber through the second oil outlet on the branch pipe. This design prevents localized overheating and ensures that the oil is evenly in contact with the front and rear heat sinks. Heat is dissipated into the air through the front and rear heat sinks, thereby improving heat dissipation efficiency, ensuring stable operation of the transformer in high-temperature environments, and extending the service life of the equipment.

The oil enters the interior of the oil inlet pipe 601 and is then introduced into the oil flow chamber through the first oil outlet hole 602 on the oil inlet pipe 601. At the same time, the oil is dispersed through the diversion pipes 604 on both sides of the oil inlet pipe 601, and then the oil is evenly distributed into the oil flow chamber through the second oil outlet holes 605 on the diversion pipe 604.

Several oil holes 703 are opened on the surface of the oil outlet pipe 701. The oil inside the oil flow chamber enters the interior of the oil outlet pipe 701 through the oil holes 703, and the oil flows out of the radiator through the oil outlet pipe 701.

[0037] The implementation principle of a novel plate-type radiator for transformers in this application embodiment is as follows: During use, oil enters the interior of the oil inlet pipe 601, and then the oil is introduced into the oil flow chamber through the first oil outlet hole 602 on the oil inlet pipe 601. At the same time, the oil is dispersed through the branch pipes 604 on both sides of the oil inlet pipe 601, and then the oil is evenly distributed into the interior of the oil flow chamber through the second oil outlet hole 605 on the branch pipe 604, avoiding local overheating. This ensures that the oil is evenly in contact with the front heat sink 1 and the rear heat sink 3, and the heat is dissipated into the air through the front heat sink 1 and the rear heat sink 3, thereby improving the heat dissipation efficiency, ensuring the stable operation of the transformer in high-temperature environments, and extending the service life of the equipment.
