Technical field

On the other hand, it takes fresh outdoor air through sterilization, disinfection, filtration and other measures before inputting it into the room. , so that there is fresh and clean air in the room every moment.

Existing fresh air fans usually adopt a chassis structure, and the chassis is equipped with components such as fans, filters, and heat exchangers. However, the internal structural layout of the existing chassis is relatively complex and the space utilization rate is not high, which affects the miniaturization of the equipment. In particular, due to space limitations of the heat exchanger, the heat exchange efficiency is not high, which affects the heat exchange performance of the fresh air blower.

Therefore, how to simplify the internal structure of the fresh air blower chassis and improve its space utilization and heat exchange efficiency of the heat exchanger has become a technical problem that needs to be solved by this utility model.
