Description

Technical Field

[0001] This utility model relates to the technical field of transformer cores, specifically to an auxiliary cooling transformer core. Background Technology

[0002] Dry-type transformers are widely used in local lighting, high-rise buildings, airports, docks, CNC machinery and equipment and other places. Simply put, a dry-type transformer is a transformer whose core and windings are not immersed in insulating oil. Its body is in direct contact with the atmosphere and is suitable for relatively dry and clean indoor environments. Generally, there are two cooling methods: air self-cooling and air cooling.

[0003] During operation, the heat generated by the core of a dry-type transformer cannot be effectively exchanged with the outside air through heat transfer in a timely manner. This results in an excessively high internal temperature in the transformer core, which seriously affects the performance of electronic components and reduces their lifespan. Summary of the Invention

[0004] The purpose of this invention is to provide an auxiliary cooling transformer core to solve the above-mentioned defects caused by the prior art.

[0005] An auxiliary cooling transformer core includes a positioning frame, silicon steel plates, and a partition plate. Multiple sets of silicon steel plates are arranged on one side of the positioning frame, and a partition plate is arranged on one side of each silicon steel plate. A positioning mechanism is provided on the outer side of the positioning frame to secure the multiple sets of silicon steel plates and the positioning frame, thereby facilitating the separation and assembly of the silicon steel plates. A heat dissipation mechanism is provided on the outer side of the partition plate to accelerate airflow near the silicon steel plates, thereby improving the heat exchange efficiency of the heat sink and enhancing the heat dissipation effect.

[0006] Preferably, the positioning mechanism includes fastening holes, an outer groove, a threaded rod, a positioning rod, a nut, and a rubber gasket. The fastening holes are symmetrically opened through the outer side of the positioning frame. An outer groove is opened on the outer side of the positioning frame. Threaded rods are equally spaced through the outer side of the positioning frame. A positioning rod is connected to the other side of the threaded rod. A rubber gasket is through the outer side of the threaded rod. The rubber gasket is disposed on one side of the positioning frame. A nut is threadedly connected to the outer side of the threaded rod.

[0007] Preferably, the threaded rod is connected to the outside of the positioning frame via a nut connected to one side.

[0008] Preferably, the heat dissipation mechanism includes a base plate, a partition plate, an air inlet slot, a ventilation slot, and internal toothed posts. An air inlet slot is provided through one side of the partition plate, and ventilation slots are provided through the outer side of the partition plate at equal intervals. A base plate is provided directly below the partition plate, and internal toothed posts are provided through the inner side of the partition plate at equal intervals. Positioning rods are provided through the outer side of the partition plate at equal intervals.

[0009] Preferably, the partition plate is connected to the top of the base plate via internal toothed posts that are equally spaced through at the bottom.

[0010] Preferably, the silicon steel insert is connected to the threaded rod via a through-connected positioning rod.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] 1. During use, the two sets of silicon steel fins are separated by a partition plate in the middle, which prevents heat from accumulating in the middle of the multiple sets of silicon steel fins during operation, thus affecting the effective heat dissipation. The partition plate allows the heat from the two sets of silicon steel fins to circulate and dissipate through the middle, shortening the time required for the equipment to dissipate heat.

[0013] 2. The corrugated support plate at the bottom increases the ventilation at the bottom, preventing heat from accumulating on the surface of the plate-mounted support plate and affecting the heat dissipation efficiency of the iron core. The positioning brackets on both sides are used to position the assembled iron cores on both sides. Attached Figure Description

Multiple sets of silicon steel plates 2 are arranged on one side of the positioning frame 1, and a partition plate 9 is arranged on one side of the silicon steel plates 2. A positioning mechanism 8 is arranged on the outer side of the positioning frame 1. The positioning mechanism 8 secures the multiple sets of silicon steel plates 2 and the positioning frame 1, thereby facilitating the separation and assembly of the silicon steel plates 2. A heat dissipation mechanism 10 is arranged on the outer side of the partition plate 9, thereby accelerating airflow near the silicon steel plates 2, improving the heat exchange efficiency of the heat sink, and enhancing the heat dissipation effect.

[0022] In this embodiment, the positioning mechanism 8 includes a fastening hole 3, an outer groove 4, a threaded rod 5, a positioning rod 6, a nut 13, and a rubber gasket 14. The fastening hole 3 is symmetrically opened through the outer side of the positioning frame 1. The outer groove 4 is opened on the outer side of the positioning frame 1. The threaded rod 5 is equally spaced through the outer side of the positioning frame 1. The positioning rod 6 is connected to the other side of the threaded rod 5. The rubber gasket 14 is through the outer side of the threaded rod 5 and is disposed on one side of the positioning frame 1. The nut 13 is threadedly connected to the outer side of the threaded rod 5.

[0023] In this embodiment, the threaded rod 5 is connected to the outside of the positioning frame 1 via a nut 13 connected to one side. The nut 13 is used to rotate and lock the outside of the threaded rod 5, which facilitates the disassembly and assembly of the device.

[0024] In this embodiment, the heat dissipation mechanism 10 includes a base plate 7, a partition plate 9, an air inlet slot 11, a ventilation slot 12, and internal toothed posts 15. An air inlet slot 11 is provided through one side of the partition plate 9, and ventilation slots 12 are provided through the outer side of the partition plate 9 at equal intervals. The base plate 7 is provided directly below the partition plate 9, and internal toothed posts 15 are provided through the interior of the partition plate 9 at equal intervals. Positioning rods 6 are provided through the outer side of the partition plate 9 at equal intervals. The positioning rods 6 are positioned by multiple sets of silicon steel inserts 2.

[0025] In this embodiment, the partition plate 9 is connected to the top of the support plate 7 through the internal toothed posts 15 that are equally spaced through the bottom end, and the internal toothed posts 15 are connected to the top of the support plate 7.

[0026] In this embodiment, the silicon steel insert 2 is connected to the threaded rod 5 via a through-connected positioning rod 6, and the threaded rod 5 is used to position and lock the positioning frame 1.

[0027] In practical applications, the working process of this type of auxiliary cooling transformer core includes the following:

[0028] Step 1: The operator first inserts multiple sets of positioning rods 6 through the outside of the partition plate 9, and at the same time, the internal toothed post 15 at the bottom of the partition plate 9 is attached to the top of the support plate 7. Screws are inserted into the inside of the internal toothed post 15 to lock the connection between the partition plate 9 and the support plate 7, thereby completing the positioning of the support plate 7. The operator then inserts multiple sets of silicon steel inserts 2 through the outside of the positioning rods 6 in sequence.

[0029] Step 2: The operator attaches the positioning frame 1 on both sides to one side of the manganese steel insert 2 on the outside, inserts the rubber gasket 14 through the outside of the threaded rod 5, and at the same time connects the outside of the threaded rod 5 on the positioning rod 6 through the positioning frame 1. The nut 13 is rotated and locked to the threaded rod 5. The nut 13 and the fastening hole 3 on the outside of the positioning frame 1 are used to lock the base plate 7.

[0030] Step 3: After fixing, the fan inside the transformer blows outside air into the inside of the transformer shell, and then blows cold air into the air inlet slot 11. The ventilation slot 12 is used to inject air into the ventilation slots 12 set on both sides, and the ventilation slots 12 are used to inject cold air into the silicon steel inserts 2 set on both sides, thereby removing the surface temperature of the silicon steel inserts 2.

[0031] Therefore, the above-disclosed embodiments are merely illustrative in all respects and are not the only ones. All modifications within the scope of this utility model or its equivalents are included in this utility model.
