Description

Technical Field

[0001] The utility model relates to the technical field of medium frequency melting furnaces, in particular to a cooling device for a medium frequency melting furnace. Background Art

[0002] The medium frequency melting furnace is a small transistor-type medium and high frequency induction heating device. Its main features are: lightweight equipment, fast heating speed, and high efficiency. It is mainly used for melting carbon steel, alloy steel and special steel, or melting and heating non-ferrous metals such as copper and aluminum.

[0003] Patent number CN209877621U discloses a metal medium-frequency melting furnace, comprising a furnace body with tilting assemblies connected to both sides. Brackets are mounted below each of the tilting assemblies, and a connecting beam is installed between the two brackets. A support base rests on the connecting beam, and a foot-operated jack is mounted above the support base. A heightening support plate is connected to the top of the foot-operated jack, with the top of the foot-operated jack located at the intersection of the diagonal lines of the heightening support plates. This medium-frequency melting furnace eliminates the need to locate heightening blocks of varying heights when using a cylinder to support metal, saving time. When heightening blocks are required to support the metal cylinder, the support base can be removed from the connecting beam and placed on the ground. The height of the heightening support plate can then be adjusted using the foot-operated jack, and the metal cylinder can then be placed on the heightening support plate. This eliminates the need for temporary heightening blocks, making it more convenient. However, the furnace lacks a cooling mechanism during operation, preventing timely heat dissipation from the furnace.

[0004] When the medium frequency melting furnace is working, the heat generated inside cannot meet the heat dissipation needs by relying solely on natural cooling, and cannot be dissipated in time, which can easily cause the internal mechanical equipment to be subjected to excessively high temperatures, causing damage to the equipment and affecting normal use.
