[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0025] Depend on Figure 1-5 The present invention relates to a transformer core that facilitates heat dissipation, comprising laminated laminations 1, multiple laminated laminations 1 tightly attached to form a core, and a core heat dissipation assembly 2 provided on the inner side of the core.
[0026] The iron core heat dissipation assembly 2 includes a fixed tube 201 disposed in the middle of the inner side of the iron core, side boxes 202 symmetrically installed on both sides of the fixed tube 201, sliding grooves 203 equally spaced at the top and bottom of the side boxes 202, first screw cylinders 204 installed at both ends of the side boxes 202, a clamping heat dissipation unit 205 installed on the side boxes 202, and various heat dissipation units 206 installed inside the fixed tube 201.
[0027] The clamping heat dissipation unit 205 includes a sliding plate 2051 symmetrically and movably installed inside the side box 202. Clamping plates 2052 are equidistantly installed on both the upper and lower sides of the sliding plate 2051. The clamping plates 2052 correspond one-to-one with the sliding grooves 203, and the corresponding clamping plates 2052 clamp the iron core. The outer wall of the sliding plate 2051 is in close contact with the inner wall of the fixing tube 201. Two limiting plates 2053 are installed on the side of the clamping plate 2052 closest to the iron core, respectively contacting and limiting the movement of the inner and outer walls of the iron core. The side of the clamping plate 2052 furthest from the iron core... The first screw 204, which is equipped with heat dissipation fins 2054, has a push screw 2055 installed on its internal threads. One end of the push screw 2055 is equipped with a limiting block, which is rotatably installed inside a limiting slot. The limiting slot is opened inside the slide plate 2051. When the slide plate 2051 moves, the two clamping plates 2052 clamp the iron core, and the two limiting plates 2053 contact the inner and outer side walls of the iron core respectively to limit the movement, which facilitates the fixing of the iron core. At the same time, the heat dissipation fins 2054 on the clamping plates 2052 can dissipate heat from the iron core.
[0028] The multi-functional heat dissipation unit 206 includes a heat dissipation pipe 2061 movably installed inside a fixed pipe 201. The outer wall of the heat dissipation pipe 2061 is in close contact with the inner wall of the fixed pipe 201. A top groove 2062 is formed at the top end of the fixed pipe 201. A top plate 2063 is installed at the top end of the heat dissipation pipe 2061. The top plate 2063 is slidably connected to the top groove 2062. A fixed plate 2064 is fixedly installed at the top end of the fixed pipe 201. A second screw cylinder 2065 is threaded onto the fixed plate 2064. An I-shaped columnar limiting block is installed at one end of the second screw cylinder 2065. The I-shaped columnar limiting block is rotatably connected to the top plate 2063. Multiple heat dissipation plates 2067 are staggered inside the heat dissipation pipe 2061. The portion of the heat dissipation pipe 2061 with heat dissipation plates 2067 forms a heat dissipation section, and the portion of the heat dissipation pipe 2061 without heat dissipation plates 2067 forms a connecting section. The outer wall of the slide plate 2051 is in close contact with the inner wall of the side box 202, and the outer wall of the heat dissipation pipe 2061 is in close contact with the inner wall of the fixed pipe 201. When the connecting section of the heat dissipation pipe 2061 extends, it can be connected to the fan for convenient air cooling. When the heat dissipation section of the heat dissipation pipe 2061 extends, it can be inserted into the cooling water for convenient water cooling, improving the versatility of heat dissipation and facilitating heat dissipation under different conditions.
[0029] Working principle: During operation, multiple laminates 1 are first stacked to form an iron core. A fixing tube 201 is set inside the iron core. Then, the push screw 2055 is turned. Since the push screw 2055 is threadedly connected to the first screw barrel 204, the sliding plate 2051 is pushed towards the iron core, so that the corresponding clamping plates 2052 on both sides clamp the iron core. At the same time, the two limiting plates 2053 on the sliding plate 2051 limit the inner and outer walls of the iron core respectively, which facilitates the fixing of the iron core. Heat dissipation fins 2054 are installed at equal intervals on the clamping plates 2052 to dissipate heat from the iron core.
[0030] Because the outer wall of the slide plate 2051 is in close contact with the inner wall of the side box 202, and the outer wall of the heat dissipation pipe 2061 is in close contact with the inner wall of the fixed pipe 201, the heat of the iron core can be conducted to the heat dissipation plate 2067. Tightening the connecting screw 2066, since the connecting screw 2066 is threadedly connected to the second screw 2065, pulls the connecting section of the heat dissipation pipe 2061 to extend to the outside of the fixed pipe 201, so that the connecting section of the heat dissipation pipe 2061 is connected to the fan, and the heat dissipation effect is achieved by air cooling of the heat dissipation plate 2067. When the heat dissipation pipe 2061 is pushed to move in the opposite direction, the heat dissipation section of the heat dissipation pipe 2061 is extended and inserted into the cooling water, and the heat dissipation effect is achieved by water cooling of the heat dissipation plate 2067, which improves the diversity of heat dissipation and facilitates heat dissipation.
