[0002] A heat treatment furnace refers to an electric furnace or fuel furnace used for heating the charge for heat treatment. Commonly used heat treatment furnaces include box-type resistance furnaces, pit-type resistance furnaces, gas carburizing furnaces and salt bath furnaces.

[0003] The heat treatment furnace processes the material by heating the device. Therefore, when the device is in use, a large amount of heat flow will be generated inside it, causing the entire device to gradually become hotter. If it is not cooled down, it will cause the device to overheat and overload, affecting its normal use. The existing cooling method generally uses a fan for air cooling, but this cooling method is too single, and the actual heat dissipation efficiency is not high. It is impossible to cool and reflux the heat flow generated inside the device, which limits the heat dissipation efficiency of the device.

[0004] Therefore, we provide a heat treatment furnace side cooling device. Utility Model Content
