[0024] 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.

[0025] Please see Figure 1-6This utility model provides a technical solution: a transformer core with rapid heat dissipation, comprising: two bottom frames 1, vertical frames 101 fixedly connected to both ends and the middle of the top of the two bottom frames 1, three of the six vertical frames 101 on the same side forming a group, top frames 102 fixedly connected to the top of the two groups of vertical frames 101, multiple silicon steel sheets 103 attached to the inner sides of the two bottom frames 1, the two groups of vertical frames 101 and the two top frames 102, and multiple transversely extending inwards on one side of the two bottom frames 1 and the two top frames 102. Ventilation slots 107, multiple horizontal ventilation slots 107 extend inward to both ends of multiple silicon steel sheets 103, and multiple vertical ventilation slots 108 extend inward on one side of each of the six vertical frames 101. The multiple vertical ventilation slots 108 extend inward to both ends and the middle part of multiple silicon steel sheets 103, two bottom frames 1 form a group, and two top frames 102 form a group. Two fastening components 2 are provided inside both ends of each group of bottom frames 1 and top frames 102, and one end of each fastening component 2 is provided with a convenient installation and disassembly component 3.

[0026] Specifically: Insert the fastening nail 201 through the through hole, then embed one end of the fastening sleeve 204 into the interior of one end of the mounting sleeve 301, align the other end of the fastening sleeve 204 with the fastening nail 201, and use a hammer to strike the other end of the mounting sleeve 301 to install the fastening assembly 2. This design facilitates the installation and removal of the iron core. When the iron core heats up, the heat is transferred to the cooler air inside the horizontal ventilation slot 107 and the vertical ventilation slot 108, which achieves rapid heat dissipation. The surfaces of the multiple silicon steel sheets 103 are coated with an insulating layer to reduce eddy current losses. The depth of the horizontal ventilation slot 107 and the vertical ventilation slot 108 opened on both sides of the multiple silicon steel sheets 103 shall not exceed one-sixth of the thickness of the multiple silicon steel sheets 103 to ensure that sufficient magnetic flux can be conducted.

[0027] In one embodiment, two ends of the bottom of one bottom frame 1 are fixedly connected to n-shaped support bases 104, and the top of the two n-shaped support bases 104 are provided with T-shaped grooves. Two ends of the bottom of the other bottom frame 1 are fixedly connected to T-shaped plates 105. The surfaces of the two T-shaped plates 105 are correspondingly and movably fitted into the interior of the T-shaped grooves on the top of the two n-shaped support bases 104. The top ends of the two n-shaped support bases 104 are provided with through mounting holes 106.

[0028] Specifically, such as Figure 1-2 As shown: T-slots are provided on the top of both n-type support bases 104 to provide movement space for the two T-shaped plates 105, while limiting the movement of the bottom frame 1, vertical frame 101 and top frame 102 on the other side; insulating foot pads (not shown) are pasted on the bottom of the n-type support bases 104 to prevent short circuits.

[0029] In one embodiment, the fastening assembly 2 includes a fastening pin 201, one end of which has a tightening groove 202, and both sides of the arc-shaped surface of the fastening pin 201 are fixedly connected to triangular limiting blocks 203.

[0030] Specifically, such as Figure 4 As shown: The fastening nail 201 is made of metal with a certain degree of toughness, which ensures that after one end of the triangular limiting block 203 and the fastening nail 201 is deformed under the pressure of the fastening sleeve 204, it can still return to its original shape after the pressure of the triangular limiting block 203 and the fastening nail 201 is removed.

[0031] In one embodiment, a fastening sleeve 204 is movably fitted onto the arc-shaped surface of the fastening nail 201. One end of the arc-shaped surface of the fastening sleeve 204 has an installation groove 205, and one end of the fastening sleeve 204 is attached to one end of the two triangular limiting blocks 203.

[0032] Specifically, such as Figure 4 As shown: The outer diameter of one end of the fastening sleeve 204 with the mounting groove 205 is slightly larger than the distance between the two ends of the triangular limiting blocks 203 away from the fastening nail 201, to ensure the insertion and removal of the disassembly sleeve 302.

[0033] In one embodiment, the easy-installation and disassembly assembly 3 includes an installation sleeve 301 and a disassembly sleeve 302.

[0034] Specifically, such as Figure 6 As shown: The inner diameter of the disassembly sleeve 302 is slightly smaller than the inner diameter of the fastening sleeve 204. When most of the triangular limiting block 203 is embedded inside the disassembly sleeve 302, the distance between the ends of the two triangular limiting blocks 203 away from the fastening nail 201 after shrinkage is less than the inner diameter of the fastening sleeve 204, and the slidable fastening sleeve 204 is fitted on the surface of the remaining triangular limiting block 203.

[0035] In one embodiment, the surfaces of multiple fastening nails 201 are correspondingly and movably embedded on the upper and lower sides of the two bottom frames 1 and the two top frames 102, and the surfaces of multiple fastening nails 201 are correspondingly and movably embedded inside the four corners of multiple silicon steel sheets 103. Two opposite triangular limiting blocks 203 form a group, and one end of the surface of any group of triangular limiting blocks 203 can be movably embedded inside the disassembly sleeve 302.

[0036] Specifically, such as Figure 6 As shown: This facilitates the disassembly of the fastening sleeve 204 using the disassembly sleeve 302.

[0037] In one embodiment, the interior of the mounting sleeve 301 can be fitted inside any mounting slot 205.

[0038] Specifically, such as Figure 5 As shown: This facilitates the installation of the fastening sleeve 204 using the installation sleeve 301.

[0039] Working principle: Multiple silicon steel sheets 103 are stacked and placed on top of two n-shaped support bases 104, so that the multiple silicon steel sheets 103 are located inside the two bottom frames 1, two vertical frames 101, and two top frames 102. The bottom frames 1, vertical frames 101, and top frames 102 with T-shaped plates 105 are pushed, so that the two sides of the silicon steel sheets 103 are attached to the inside of the two bottom frames 1, two vertical frames 101, and two top frames 102, and the mounting holes of multiple fastening screws 201 are aligned accordingly. The fastening screws 201 are inserted through the through holes in sequence, and then the fastening sleeves 204 are closed. The surface of the mounting sleeve 301 is embedded in the interior of one end of the mounting sleeve 301. The other end of the fastening sleeve 204 is aligned with the fastening nail 201. The other end of the mounting sleeve 301 is struck with a hammer. The mounting sleeve 301 pushes the fastening sleeve 204 onto the surface of the fastening nail 201. Under the pressure of the fastening nail 201, the two triangular limiting blocks 203 cause the two sides of one end of the fastening nail 201 to move and deform into the tightening groove 202. When the fastening sleeve 204 moves to the appropriate position, the triangular limiting blocks 203 lose the pressure of the fastening sleeve 204 and return to their original state under the action of elasticity, thus completing the installation of the fastening component 2.

[0040] During disassembly, align the inside of one end of the disassembly sleeve 302 with the fastening nail 201, and use a hammer to strike the other end of the disassembly sleeve 302. The disassembly sleeve 302 will press against the triangular limiting block 203, causing both sides of one end of the fastening nail 201 to move and deform into the tightening groove 202. Continue to strike the installation sleeve 301 until most of the triangular limiting block 203 is embedded inside the disassembly sleeve 302. Since the inner diameter of the disassembly sleeve 302 is slightly smaller than the inner diameter of the fastening sleeve 204, when most of the triangular limiting block 203 is embedded inside the disassembly sleeve 302, the fastening sleeve 204 can be slidably placed on the surface of the remaining part of the triangular limiting block 203. Striking the other end of the fastening sleeve 204 will cause the fastening sleeve 204 to move the disassembly sleeve 302 towards the edge of the fastening nail 201 until the disassembly of the fastening sleeve 204 is completed.

[0041] This design facilitates the installation and disassembly of the transformer core.

[0042] An intake fan and an exhaust fan are installed on both sides of the transformer. The intake fan draws in cooler outside air into the transformer. When the iron core heats up, the heat is transferred to the cooler air inside the horizontal ventilation slot 107 and the vertical ventilation slot 108. The warmer air is discharged from the transformer by the exhaust fan. This cycle repeats to achieve the purpose of heat dissipation.

[0043] This design allows the transformer core to dissipate heat quickly.

[0044] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
