The crossflow fan is not directly responsible for heat dissipation in the oven, but it achieves uniform heat distribution by circulating air. The oven is usually equipped with heating elements, such as electric heating wires or gas flames, which generate heat, and the crossflow fan acts to spread this heat evenly to all corners of the oven, so that the food is evenly heated.

To achieve the heat dissipation effect, the oven is usually designed with heat dissipation structures, such as heat dissipation holes or radiators, which are used to dissipate the heat accumulated inside the oven to the external environment. These heat dissipation structures are usually located on the side or back of the oven and continue to dissipate heat when the oven is running, thereby maintaining the temperature of the oven and ensuring that it does not overheat.

Therefore, the crossflow fan and the heat dissipation structure are two no longer components in the oven, each of which is responsible for ensuring that the heat is evenly distributed and dissipated, so as to achieve effective baking and heat dissipation effects.
