Crossflow fans achieve uniform heating in ovens by:

1. Circulating air: Crossflow fans circulate hot air evenly throughout the oven by pushing air. They are usually located at the back or top of the oven and have powerful fans that can produce strong airflow. By circulating the air, crossflow fans blow hot air from the heating element to all corners of the oven, ensuring that the food is evenly heated throughout the oven.

2. Direction of air flow: Crossflow fans usually blow hot air from the back or top of the oven to the front or bottom. This direction of air flow helps transfer heat from the back or top to the surface of the food and circulates the hot air inside the oven. This circulating air flow ensures that both the surface and bottom of the food receive relatively uniform heat, avoiding local overheating or uneven burning of the food.

3. Temperature control: The use of crossflow fans also helps to better control the oven temperature. They can help maintain temperature stability inside the oven. When the oven temperature exceeds the set value, the crossflow fan will help dissipate heat to prevent overheating. Conversely, when the oven temperature drops, the crossflow fan circulates hot air into the oven, raising the temperature. Through precise temperature control, the crossflow fan ensures that the food is evenly heated in a constant temperature environment.

4. Multi-layer cooking: The circulating air flow of the crossflow fan makes it possible to cook multiple layers simultaneously in the oven. Whether it is at different levels in the oven or at different positions in the baking tray, the crossflow fan can evenly distribute the hot air to each layer of food, ensuring that they are all properly heated.

By circulating air, controlling temperature and air flow direction, the crossflow fan achieves uniform heating in the oven, so the crossflow fan plays an important role in the oven.
