Description

Technical Field

[0001] This utility model relates to the field of transformer technology, and in particular to a housing for a low-temperature transformer coil. Background Technology

[0002] Transformers are key equipment in power systems for power transmission and voltage transformation, and their operational reliability directly affects the stability of the entire power grid. During operation, transformers generate a large amount of heat due to copper losses in the coils and iron losses in the core, causing their temperature to rise. Excessive temperature accelerates the aging of transformer insulation materials, reducing their insulation performance and service life, and in severe cases, even leading to failures and significant economic losses. Therefore, the heat dissipation capacity of a transformer is one of the core indicators for evaluating its performance and design level.

[0003] The heat source of a transformer mainly comes from its internal coils. Heat is transferred from the inside of the coils to their surface, then through insulating oil or air to the transformer casing, and finally dissipated through the external cooling system. This heat transfer path is long and has high thermal resistance, resulting in persistently high operating temperatures (temperature rise) of the coils themselves, becoming a bottleneck restricting the improvement of transformer capacity and lifespan. Especially for compact, high-capacity transformers or those requiring high reliability, it is crucial to efficiently and quickly dissipate the heat generated by the coils to fundamentally reduce the coil temperature.

[0004] Therefore, there is an urgent need in this field for a new type of coil heat dissipation solution that is structurally sound, easy to manufacture, efficient and reliable, capable of directly and efficiently cooling the heat source (coil), shortening the heat dissipation path, significantly reducing the temperature rise of the coil body, thereby improving the load capacity, operating efficiency and service life of the transformer.

[0007] Preferably, the second heat dissipation duct penetrates the upper and lower surfaces of the housing.

[0008] Preferably, the cross-section of the second heat dissipation duct is rectangular.

[0009] Preferably, the second heat dissipation air duct is provided with 4-8 ducts.

[0021] The following is combined Figures 1 to 3 This describes the housing of a low-temperature rise transformer coil according to an embodiment of the present invention.

[0022] A housing for a low-temperature transformer coil includes a housing 1, which is elliptical in shape and has an interior cavity. A first heat dissipation channel 2 is provided inside the wall of the housing 1, and several first heat dissipation channels 2 are provided around the interior of the wall of the housing 1. The first heat dissipation channels 2 are located on the side close to the interior cavity of the housing 1. A mounting block 3 protrudes from the front end of the housing 1, and several second heat dissipation channels 4 are provided on both sides of the mounting block 3.

[0023] A housing for a low-temperature transformer coil is disclosed, used to mount the transformer coil. Several first heat dissipation channels 2 are arranged around the inner perimeter of the housing 1 wall to quickly dissipate generated heat and prevent it from concentrating inside the housing 1. A mounting block 3 is used for mounting other components and the coil. Several second heat dissipation channels 4 are arranged on both sides of the mounting block 3, further dissipating heat and improving the heat dissipation effect of the housing 1, thereby enhancing the transformer's load capacity, operating efficiency, and service life.

[0024] Specifically, the second heat dissipation channel 4 penetrates the upper and lower surfaces of the housing 1. This allows heat to dissipate from the upper and lower surfaces of the housing 1, facilitating heat dissipation. The second heat dissipation channel 4 is arranged parallel to the housing 1 to prevent it from bending, further aiding in heat dissipation. The housing 1 and the second heat dissipation channel 4 are integrally manufactured, saving manufacturing time and costs.

[0025] To further explain, the second heat dissipation duct 4 has a rectangular cross-section. This facilitates heat dissipation from the second heat dissipation duct 4, and provides a large heat dissipation surface.

[0026] To further explain, there are 4-8 second heat dissipation ducts 4. This number facilitates the arrangement of the second heat dissipation ducts 4 on both sides of the mounting block 3. There are 2-4 second heat dissipation ducts 4 on one side, and the second heat dissipation ducts 4 on one side are arranged in a row. This number of second heat dissipation ducts 4 can be arranged exactly on the side of the mounting block 3, which helps to dissipate heat. This facilitates the dissipation of heat inside the housing 1.

[0027] Specifically, the first heat dissipation channel 2 penetrates the upper and lower surfaces of the housing 1. This allows heat to dissipate from the upper and lower surfaces of the housing 1, facilitating heat dissipation. The first heat dissipation channel 2 is arranged parallel to the housing 1, preventing it from bending and further aiding in heat dissipation. The housing 1 and the first heat dissipation channel 2 are integrally manufactured, saving manufacturing time and costs. The first heat dissipation channel 2 surrounds the housing 1, enabling rapid dissipation of heat from inside the housing 1.

[0028] To further explain, the first heat dissipation duct 2 has a rectangular cross-section. This facilitates heat dissipation, and the large heat dissipation surface allows it to surround and cover the housing 1, thus aiding in heat dissipation.

[0029] To further explain, the first heat dissipation air duct 2 is provided with 40-60 ducts. This number allows the first heat dissipation air duct 2 to be arranged around the housing 1, achieving full coverage of the housing 1, resulting in good heat dissipation effect and fast heat dissipation speed.

[0030] Specifically, heat dissipation conduits 5 are provided inside the wall of the shell 1, and the heat dissipation conduits 5 are arranged around the shell 1. The heat dissipation conduits 5 further dissipate heat, ensuring that the temperature inside the shell 1 drops rapidly. There are 8-15 layers of heat dissipation conduits 5, and each layer of heat dissipation conduits 5 is evenly arranged from the top to the bottom of the shell 1, which enables further rapid heat dissipation inside the shell 1. The heat dissipation conduits 5 mentioned here refer to the heat dissipation conduits 5 being arranged in the cross-sectional shape of the shell 1, that is, the shell 1 is evenly arranged with heat dissipation conduits 5 from top to bottom.

[0031] Specifically, the first heat dissipation duct 2 is located near the mounting cavity of the housing 1, and the heat dissipation conduit 5 is located near the outer side of the housing 1. Heat is dissipated from the first heat dissipation duct 2, and the heat dissipation conduit 5 can further reduce the temperature of the heat in the first heat dissipation duct 2.
