贯流风机在微波炉中帮助防止过热的主要方式是通过散热和热空气的排出。

When a microwave oven is running, the microwave energy is converted into heat energy, causing the temperature inside the microwave oven to rise. Without a proper heat dissipation system, the temperature may rise to too high a level, causing the microwave oven to overheat or even cause a malfunction.

Here are the ways that crossflow fans help prevent microwave ovens from overheating:

1. Heat dissipation: Crossflow fans help reduce the temperature by exhausting hot air from the inside of the microwave oven. They push the hot air out of the microwave oven and allow fresh air to enter, effectively reducing the internal temperature of the microwave oven. This helps prevent the microwave oven from overheating and maintains the normal operating temperature of the unit.

2. Exhaust of hot air: Crossflow fans quickly exhaust the hot air generated inside the microwave oven to prevent the hot air from accumulating inside the microwave oven. By effectively exhausting the hot air, crossflow fans help maintain good air flow inside the microwave oven, preventing heat accumulation and overheating.

The heat dissipation and exhaust functions of crossflow fans can effectively control the temperature of the microwave oven and prevent overheating. They help protect the internal components and circuits of the microwave oven from damage caused by excessive temperatures, extend the service life of the microwave oven, and provide a safer and more reliable user experience.
