Crossflow fans help keep the temperature inside the microwave oven stable by:

1. Heat dissipation: Crossflow fans help dissipate heat and lower the temperature by pushing hot air out of the microwave oven. When the microwave oven is working, the heater and other electronic components inside generate heat. The crossflow fan blows the hot air away from these components, allowing fresh air to enter, effectively lowering the temperature inside the microwave oven.

2. Air circulation: Crossflow fans help evenly distribute and regulate temperature by pushing air to establish circulation inside the microwave oven. They introduce fresh air into the microwave oven and push hot air to various areas of the microwave oven, ensuring that the temperature is evenly distributed throughout the oven cavity and avoiding uneven temperatures.

3. Heat conduction: Crossflow fans promote heat conduction through the contact between air and heat sources such as heaters and transformers. When air comes into contact with the heat source, it absorbs heat and carries it away. This helps keep the temperature of components such as heaters stable and avoid overheating.

4. Hot air discharge: Crossflow fans quickly discharge the hot air that has been dissipated out of the oven cavity of the microwave oven. By quickly exhausting hot air, the crossflow fan helps maintain good air flow inside the microwave oven, preventing heat accumulation and overheating, thereby maintaining stable temperature.

Through heat dissipation, air circulation, heat conduction and hot air exhaust, the crossflow fan effectively controls the temperature inside the microwave oven and maintains temperature stability. It helps the normal operation of the microwave oven, provides consistent heating effects, and ensures that the equipment operates within a safe operating temperature range.
