Description

Technical Field

[0001] The utility model relates to the technical field of iron cores for medium frequency transformers, in particular to a direct water-cooled iron core device for medium frequency transformers. Background Art

[0002] Medium frequency transformers play an important role in our daily life. They can be used to adjust the voltage of medium frequency induction furnaces. Generally, the iron core uses heat sinks inserted into the iron core sheets, which are indirectly cooled by water pipes at the edge of the heat sink. However, this technology reduces the cooling effect of the iron core. Therefore, a medium frequency transformer direct water-cooling iron core device is needed.

[0003] According to the description of a direct water-cooled core device for a medium-frequency transformer disclosed on the patent website (authorization announcement number: CN206421886U), "The utility model discloses a direct water-cooled core device for a medium-frequency transformer in the technical field of core technology for a medium-frequency transformer, comprising an upper splint, an insulating plastic plate is provided at the center of the bottom of the upper splint, pillars are provided on the left and right sides of the bottom of the upper splint, and a lower splint is provided at the bottom of the two groups of pillars, an insulating shock-absorbing pad is provided at the bottom of the lower splint, an insulating barrel is provided at the center of the bottom of the insulating plastic plate, and flowing water is allowed to exist in the inner cavity of the heat-resistant glass barrel through a water injection pipe and a return pipe to reduce the temperature of the insulating heat-conductive ceramic barrel, thereby eliminating the heat generated by the core and the winding coil working together. Direct water-cooling of the core and indirect water cooling of the entire working assembly can effectively reduce the temperature rise of the core and the working assembly, avoid the influence of the working temperature rise and environmental heat radiation on the device, and improve the service life of the medium-frequency transformer. Moreover, the structure of the device is relatively compact."

[0004] In view of the above description, the applicant believes that the following problems exist: when the device is in use, an insulating barrel is used to hold water to directly dissipate heat from the iron core. Insulating cotton is provided on the outer wall of the heat-resistant glass barrel to reduce the temperature of the outer wall of the heat-resistant glass barrel to prevent burns. Copper fins are evenly provided on the outer wall of the insulated thermally conductive ceramic barrel. The copper fins have strong thermal conductivity and can increase the heat dissipation area, making it easier for the insulated thermally conductive ceramic barrel to dissipate the heat generated by thermal radiation from the insulating barrel. Water is allowed to flow in the inner cavity of the heat-resistant glass barrel through the water injection pipe and the return pipe to reduce the temperature of the insulated thermally conductive ceramic barrel. Since the device will vibrate during operation, if the device is in vibration for a long time, the stability of the device may deteriorate, thereby affecting the use of the device.
