Description

Technical Field

[0001] The utility model relates to a device for thermostatically treating nano magnetic cores, belonging to the technical field of nano crystal magnetic core processing. Background Art

[0002] Nano crystal magnetic cores are a new type of soft magnetic material with excellent soft magnetic properties such as high magnetic permeability, low coercivity, and low loss. Therefore, they have broad application prospects in the fields of power electronics, electromagnetic compatibility, etc. With the continuous progress of technology, nano crystal magnetic cores are playing an increasingly important role in multiple high-tech industries such as new energy vehicles, wireless charging, 5G communication, and photovoltaic inverters.

[0003] Chinese published patent (Publication No.: CN 218957533 U) discloses a heat treatment forming device for nano crystal magnetic cores, including a main body. A sandwich layer is arranged on the upper surface of the main body, and the sandwich layer penetrates through the side wall of the entire main body. A support block is fixedly connected to the inner bottom of the sandwich layer, a positioning column is fixedly connected to the inner bottom of the main body, a heater is fixedly connected to the inner bottom of the positioning column, a heating tube is fixedly connected to the heating end of the heater, and the heating tube is installed on the inner surface of the positioning column. A gate plate is arranged inside the sandwich layer, a positioning ring is fixedly connected to the top of the gate plate, a cover body is installed on the upper surface of the positioning ring, and a sealing ring is fixedly connected to the inner bottom of the sandwich layer and near the edge. Through the above structure, by setting through holes, a sandwich layer, a gate plate, and a cover body, it is possible to effectively realize two different heat treatment methods without taking the nano crystal magnetic cores out of the heating furnace, which is beneficial to simplifying the heat treatment forming process of nano crystal magnetic cores;

[0004] At present, the heat treatment of nano crystal magnetic cores is mainly carried out by heating and raising the temperature using a heating furnace. Although the above patent can effectively realize two different heat treatment methods without taking the nano crystal magnetic cores out of the heating furnace by setting through holes, a sandwich layer, a gate plate, and a cover body, which is beneficial to simplifying the heat treatment forming process of nano crystal magnetic cores, the nano crystal magnetic cores for heat treatment are placed above the support net, and no limiting device for limiting each nano crystal magnetic core is arranged on the support net. When the support net is not fully filled with nano crystal magnetic cores, there will be a large idle space on the support net. During the heating process of the nano crystal magnetic cores by the heating furnace, the nano crystal magnetic cores placed on the support net are prone to shaking on the support net, which may cause multiple nano crystal magnetic cores to pile up together, and when multiple nano crystal magnetic cores pile up together, the nano crystal magnetic cores cannot be evenly heated, ultimately reducing the effect of the constant temperature treatment of nano crystal magnetic cores and the practicability of the equipment.
