Description

Technical Field

[0001] This application relates to the field of heat exchange device technology, for example to a general-purpose heat exchange device for heating. Background Technology

[0002] Heating, ventilation, and air conditioning (HVAC) is a category of building equipment that is mainly responsible for regulating the temperature, humidity, and air quality within a building. HVAC systems are often used in conjunction with heat exchangers to minimize heat loss from the interior while ensuring ventilation during indoor-outdoor air exchange.

[0003] Existing HVAC heat exchange devices cannot improve heat exchange efficiency during use, are not conducive to the maintenance and replacement of internal components of the heat exchanger, and cannot effectively filter outdoor air entering the heat exchange box, thus failing to effectively prevent dust particles from entering the room.

[0004] Therefore, how to improve the heat exchange effect and better filter the outdoor air entering the heat exchange box has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below.
