[0024] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figures 1 to 5 As shown, a heat dissipation mechanism for a medium frequency induction power supply comprises a medium frequency induction power supply body 1 and a heat dissipation mechanism; a heat dissipation groove 11 is provided on a side wall of the medium frequency induction power supply body 1, and the heat dissipation mechanism is arranged in the heat dissipation groove 11; the heat generated by the medium frequency induction power supply body 1 during operation is dissipated by the heat dissipation mechanism.

[0026] The heat dissipation mechanism includes a heat dissipation plate 2, a filter screen 4, a guide assembly and a limit assembly; the heat dissipation plate 2 is arranged in a heat dissipation slot 11, and the bottom of the heat dissipation plate 2 is hingedly arranged with the heat dissipation slot 11; the bottom of the heat dissipation plate 2 is hingedly arranged with the heat dissipation slot 11, so that the heat dissipation plate 2 can be conveniently opened from the heat dissipation slot 11.

[0027] The inner side wall of the heat sink 2 is provided with a mounting groove 21, and the two side walls of the mounting groove 21 are provided with slide grooves 22; the guide assembly includes a guide block 3 and a pulley 31, the guide block 3 is arranged in the slide groove 22, and the side wall of the guide block 3 is provided with a plurality of pulleys 31; the filter 4 is arranged between the pulleys 31 on both sides; the limiting assembly includes a limiting plate 5 and a first spring 51, the side wall of the mounting groove 21 is provided with a limiting groove 23, the limiting plate 5 is arranged in the limiting groove 23, the first spring 51 is arranged between the limiting groove 23 and the limiting plate 5, and the limiting plate 5 is used to limit the top of the filter 4.

[0028] By arranging the filter 4 in the installation groove 21 in the heat sink 2, dust and impurities can be effectively prevented from entering the heat sink 11, ensuring the normal operation of the heat dissipation mechanism. At the same time, by arranging the pulley 31 and the guide block 3, the filter 4 can be ensured to slide smoothly in the installation groove 21, and the filter 4 can be easily installed and removed, which is convenient for cleaning and maintenance. After the filter 4 is installed, the elastic force of the limit block and the first spring 51 ensures that the filter 4 remains stable in the installation groove 21.

[0029] A supporting mechanism is provided at the bottom of the mounting groove 21, and the supporting mechanism includes a supporting seat 6 and a supporting plate 61. The supporting plate 61 is provided in the supporting seat 6. A second spring 62 is provided inside the supporting seat 6. Both ends of the second spring 62 are respectively connected to the supporting seat 6 and the supporting plate 61. The supporting plate 61 supports the bottom of the filter screen 4.

[0030] The bottom of the filter screen 4 can be elastically supported by the elastic force of the support plate 61 and the second spring 62 . By being installed in conjunction with the limiting plate 5 , it can adapt to filter screens 4 of different sizes and weights, thereby improving the stability of the installation of the filter screen 4 .

[0031] A positioning mechanism is provided on the side wall of the medium frequency induction power supply body 1, and the positioning mechanism includes a positioning block 7 and a positioning plate 71. The positioning block 7 is arranged above the heat dissipation groove 11, and a third spring 72 is arranged in the positioning block 7. One end of the positioning plate 71 is arranged inside the positioning block 7 and connected to the third spring 72.

[0032] The third spring 72 and the positioning plate 71 are installed together to facilitate the installation of the heat sink 2 without requiring additional adjustment steps, thereby improving the installation efficiency. At the same time, the third spring 72 enables the positioning plate 71 to be tightly attached to the outer wall of the heat sink 2 under the elastic force, thereby achieving a stable fixing effect, preventing the heat sink 2 from loosening or shifting during operation, and improving the stability of the heat sink installation.

[0033] A first rounded corner 711 is disposed on the outer side of the positioning plate 71 .

[0035] The other side of the limiting plate 5 abutting against the top of the filter screen 4 is provided with a second rounded corner 52 .

[0036] By setting the second fillet 52, when installing the filter 4, the obstruction of the bottom of the filter 4 by the limiting plate 5 can be effectively reduced, which facilitates the installation of the filter 4 and reduces the wear of the limiting plate 5, thereby increasing the service life.

[0037] Working principle of the utility model: when the staff needs to clean and replace the filter screen 4 at the heat dissipation position in the medium frequency induction power supply, the heat dissipation plate 2 is rotated and opened through the hinged setting of the bottom of the heat dissipation plate 2 and the heat dissipation groove 11, and the limit plate 5 in the installation groove 21 is pressed. The limit plate 5 is contracted into the limit groove 23 by the elastic force of the third spring 72. At this time, the filter screen 4 moves upward under the elastic force of the bottom support plate 61 and the second spring 62, and then slides out of the heat dissipation plate 2 through the pulleys 31 on the guide blocks 3 on both sides;

[0038] After cleaning the heat sink 2, insert the bottom of the filter 4 along the slide groove 22, and insert it to the bottom of the installation groove 21 under the action of the pulleys 31 on both sides. When the bottom of the filter 4 contacts the upper end of the limiting plate 5, the limiting plate 5 is forced to shrink into the receiving groove, and the filter 4 continues to move toward the bottom of the installation groove 21 to compress the support plate 61 until the limiting plate 5 extends out to limit the top of the filter 4, and the installation work is completed.

[0039] The above embodiments are only used to illustrate the technical method of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical method of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the utility model.
