The noise and vibration of the crossflow fan may have some impact on the temperature distribution inside the oven. Here are some possible effects of noise and vibration on the temperature distribution inside the oven:

1. Uneven air circulation: Excessive noise and vibration may interfere with the normal operation of the crossflow fan, resulting in uneven air circulation. The vibration and noise of the fan may cause air flow to be blocked or turbulent, resulting in uneven distribution of hot air inside the oven. Some areas may receive more heat, while other areas may be cooler, resulting in uneven temperature distribution.

2. Impaired sealing: Strong vibration and noise may cause the oven or crossflow fan to partially or completely lose its sealing. This may cause hot air to leak out or cold air to enter the oven, thus interfering with the temperature distribution. The leaking hot air may cause some areas to overheat, while the entry of cold air may cause other areas to cool down.

3. Uneven heat dissipation: Noise and vibration may affect the heat dissipation of the crossflow fan, which in turn affects the temperature distribution inside the oven. If the efficiency of the crossflow fan is reduced or the air circulation is blocked, the heat dissipation may be uneven. This can result in some areas being hotter and others being colder, affecting the temperature distribution inside the oven.

It is important to note that the effects of noise and vibration on the temperature distribution inside the oven are usually relatively small. Ovens are usually insulated and designed to reduce the effects of noise and vibration and provide a more even temperature distribution. However, when choosing an oven, consider choosing a reliable crossflow fan with lower noise and vibration to ensure a more even temperature distribution and better cooking results. At the same time, regular maintenance and timely treatment of any abnormal noise and vibration issues will also help maintain the stability of the temperature distribution inside the oven.
