Description

Technical Field

[0001] The utility model belongs to the technical field, and specifically refers to a high-efficiency internal circulation air duct for an oven. Background Art

[0002] In the existing oven technology, traditional drying equipment usually adopts the method of directly heating by setting a heating device. This design has some obvious deficiencies in the drying process. First, the air circulation efficiency is relatively low, resulting in uneven temperature and humidity distribution in the drying chamber, thus affecting the drying effect and efficiency. Second, the heating device of the traditional oven is generally installed at the bottom or side wall of the drying chamber. This layout makes the heat transfer efficiency not high and is prone to forming heat dead zones, further affecting the drying quality. When drying copper foil, it is easy to cause the drying effect of the copper foil to be difficult to achieve the expected uniformity, affecting the quality of the copper foil. In addition, the control system of the traditional oven is relatively simple, lacking precise control of temperature and humidity during the drying process, and it is difficult to meet the high-precision drying requirements.
