Description

Sectional insulated oven

The present invention relates to an oven, in particular to a segmented heat-insulating oven.

In an existing oven for drying circuit boards, its internal space can be roughly divided into a standing zone, a heating zone and a cooling zone from the entrance to the exit in sequence. The circuit board that enters the oven will stand for a period of time before the resting area, then move to the heating area for heating and baking, and finally move to the cooling area for cooling down, and finally leave the oven to complete the drying process. However, the heating zone and the cooling zone in the existing oven circulate adjacent to each other without any unshielded objects. The heating zone is heated and baked by blowing hot air with a higher temperature, and the cooling zone is heated by blowing a higher temperature. Low cold air is used to cool down, so the heating zone will be affected by the cooling zone that blows cold air to cool down at the same time during heating and baking. This will reduce the heating efficiency and make the baking effect worse. The cooling zone will also be affected at the same time during cooling and cooling. The influence of the heating zone that blows hot air for baking reduces the cooling efficiency. Therefore, how to improve such problems will be a subject worthy of consideration.
