Crossflow fans are widely used in the following home appliance fields:

1. Air conditioners: Crossflow fans are one of the key components in air conditioning systems. They are used to dissipate heat from indoor and outdoor units, helping to remove heat and keep the air conditioning system running properly.

2. Microwave ovens: Crossflow fans are often used in microwave ovens for heat dissipation and ventilation. They help remove the heat generated by the microwave oven, ensure the normal operation of the equipment and prevent overheating.

3. Ovens: In ovens, crossflow fans are used to circulate hot air to cook food more evenly. They may provide better heat distribution, making food cooking more uniform and efficient.

4. Refrigerators and freezers: Crossflow fans are used in refrigerators and freezers to circulate cold air to keep the internal temperature stable. They help to evenly distribute cold air and improve refrigeration and freezing effects.

5. Washing machines and dryers: Crossflow fans are used in washing machines and dryers to remove moisture and heat. They help speed up the drying process of clothes and maintain the normal operating temperature of the equipment.

6. Air Purifiers: Some air purifiers use crossflow fans to inhale and circulate air in order to effectively filter and purify pollutants in the air.

7. TV and audio systems: In some high-end TV and audio systems, crossflow fans are used to dissipate heat, prevent the equipment from overheating and keep its performance stable.

The application of crossflow fans in the field of home appliances is mainly for heat dissipation and ventilation, to maintain the normal operation of the equipment and improve performance. They are not only functional, but also can provide a better user experience and ensure the reliability and life of the equipment.
