[0009] Preferably, the thickness of the extension part gradually decreases in the extension direction; the maximum length of the extension part is such that it does not hinder the winding of the winding package after extension.
[0010] Preferably, the core bottom plate, the middle column and the two baffles are integrally formed.
[0011] A transformer core assembly includes the transformer core described above, and there are two transformer cores; the two transformer cores are arranged in a butted manner to form a core body; a base is installed on the first side of the core body, and an extension part is located on the second side of the core body, and the first side and the second side are located on opposite sides of the core body; the core assembly further includes a heat dissipation water tank; the extension part is arranged in a fitting manner with the heat dissipation water tank.

[0029] Refer to Figures 1 to 2 As shown, the present utility model provides a transformer core, which includes a core base plate 1, a middle column 2 and two baffles 3, and the middle column 2 and the two baffles 3 are both connected to the core base plate 1, and the core base plate 1, the middle column 2 and the two baffles 3 are integrally formed. The two baffles 3 are arranged on one of the opposite sides of the core base plate 1; at the same side end of each of the two baffles 3, an extension part 4 extends out, and the extension parts 4 of the two baffles 3 both extend along the middle of the edge of the core base plate 1; the middle column 2 is used for installing a winding package 5, and the winding package 5 is wound around the middle column 2 to assemble the core part of the transformer.
[0030] Wherein, a heat dissipation notch 6 is respectively formed at the edges of the other opposite sides of the core base plate 1 to further dissipate heat from the transformer and avoid affecting the service life of the transformer due to excessive temperature.
[0031] The inner wall of the baffle 3 is arc-shaped in the length direction, and the arc-shaped structures of the two baffles 3 are symmetrically arranged; the arc-shaped structure of each baffle 3 is concentric with the middle column 2, which is convenient for the winding package 5 to be wound around the middle column 2.
[0032] The thickness of the extension part 4 gradually decreases in the extending direction; the maximum length of the extension part 4 is such that it does not obstruct the winding of the winding package 5 after extension, that is, to prevent the channel formed between the two baffles 3 from being closed when the extension part 4 is too long, causing phenomena such as bulges in the winding package 5 due to extrusion.
[0033] Please continue to refer to Figures 3 - 4 , a transformer core assembly, including the transformer core described above, and two transformer cores are provided; the two transformer cores are arranged in a butted and buckled manner to form a core body; a base 7 is installed on the first side of the core body, the extension part 4 is located on the second side of the core body, and the first side and the second side are on opposite sides of the core body.

By extending the end of the baffle 3 to form the extension part 4, and the extension part 4 is arranged in contact with the heat dissipation bottom plate, the contact area between the core and the heat dissipation water tank 8 is increased, and the heat dissipation effect is enhanced.
[0035] Since one end of the baffle 3 is used for mounting and contacting the base 7, and the opposite end is used for contacting the heat dissipation bottom plate of the heat dissipation water tank 8, only one end of the baffle 3 is provided with the extension part 4 to increase the contact area between the core body and the heat dissipation water tank 8.
