Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation, and specifically relates to a heat dissipation device for a yoke of an intermediate frequency electric furnace. Background Technique

[0002] An intermediate frequency electric furnace is a power supply device that converts 50HZ alternating current of industrial frequency into intermediate frequency (above 300HZ to 10,000HZ). It rectifies three-phase industrial frequency alternating current into direct current, and then converts the direct current into adjustable intermediate frequency current, supplying the intermediate frequency alternating current flowing through the capacitor and the induction coil. High-density magnetic lines of force are generated in the induction coil and cut the metal material placed in the induction coil, generating a large eddy current in the metal material;

[0003] During the working process of the intermediate frequency electric furnace, the heat generated by the yoke itself is processed by the heat dissipation modules on both sides to ensure the normal operation of the yoke. However, in actual use, it is difficult for the yoke heat dissipation module alone to quickly and effectively dissipate the heat of the yoke, affecting the normal operation of the yoke. Therefore, we propose a heat dissipation device for a yoke of an intermediate frequency electric furnace. Content of the Utility Model

[0004] The purpose of the utility model is to provide a heat dissipation device for a yoke of an intermediate frequency electric furnace, which solves the problems in the background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A heat dissipation device for a yoke of an intermediate frequency electric furnace, including a yoke body. A heat conduction frame is arranged outside the yoke body. A ventilation opening is arranged near the back of the top end of the heat conduction frame. A cavity is arranged inside the heat conduction frame. A first heat conduction fin is connected to the inner side of the heat conduction frame. One end of the first heat conduction fin is fixedly connected to the outer wall of the yoke body. A water inlet pipe is communicated and arranged near the bottom end of one side of the front of the heat conduction frame. A water outlet pipe is communicated and arranged near the bottom end of the other side of the front of the heat conduction frame. A second heat conduction fin is fixedly installed on the back of the yoke body. A heat dissipation fan is arranged below the second heat conduction fin. The heat dissipation fan is fixedly installed on the inner side of the heat conduction frame.

[0006] Preferably, the number of the first heat conduction fins is several. The other end of the first heat conduction fin fixedly penetrates through the inner side of the heat conduction frame and extends into the cavity. By extending the first heat conduction fin into the cavity, the first heat conduction fin can conduct the heat of the yoke body into the coolant in the cavity.

[0007] Preferably, the number of the second heat conduction fins is several. The shapes of the first heat conduction fin and the second heat conduction fin are both wavy. By setting both the first heat conduction fin and the second heat conduction fin to be wavy, the contact area and contact duration between the air flow and the first heat conduction fin and the second heat conduction fin can be increased, thereby further improving the heat dissipation effect of the first heat conduction fin and the second heat conduction fin.

[0008] Preferably, the materials of the first heat-conducting fin and the second heat-conducting fin are both copper.

[0009] Preferably, an anti-collision strip is fixedly installed on the outer wall of the heat-conducting frame. By providing the anti-collision strip, it can play a certain protective role for the heat-conducting frame, avoiding collision deformation of the heat-conducting frame during installation and use, which may affect subsequent normal use.

[0010] Preferably, the material of the anti-collision strip is high-temperature resistant rubber, and the number of the anti-collision strips is several.

[0011] The utility model provides a heat dissipation device for a magnetic yoke of an intermediate frequency electric furnace. The heat dissipation device for the magnetic yoke of the intermediate frequency electric furnace has the following beneficial effects:

[0012] (1) For the heat dissipation device of the magnetic yoke of the intermediate frequency electric furnace, the first heat-conducting fin will conduct the heat on the magnetic yoke body into the coolant, and the coolant will flow out through the water outlet pipe to ensure the cooling effect of the coolant in the cavity. Moreover, the second heat-conducting fin will quickly conduct the heat on the magnetic yoke body, and the heat dissipation fan will blow towards the second heat-conducting fin, which can improve the heat dissipation efficiency of the heat-conducting fin. By setting both the first heat-conducting fin and the second heat-conducting fin in a wavy shape, it can increase the contact area and contact duration between the air flow and the first heat-conducting fin and the second heat-conducting fin, thereby further improving the heat dissipation effect of the first heat-conducting fin and the second heat-conducting fin;

[0013] (2) For the heat dissipation device of the magnetic yoke of the intermediate frequency electric furnace, by providing the anti-collision strip, it can play a certain protective role for the heat-conducting frame, avoiding collision deformation of the heat-conducting frame during installation and use, which may affect subsequent normal use. The structure is simple and the practicability is strong. Description of the Drawings
