Description

technical field

[0001] The invention relates to an electric heat exchanger for a ventilation device, in particular to a novel electric heat exchanger which improves the air channel structure of the electric heat exchanger and improves the heat exchange efficiency between outdoor air and indoor air. Background technique

[0002] In a confined space, with the respiration of organisms, the concentration of carbon dioxide increases continuously, and when it reaches a certain concentration, it will affect the respiratory function of organisms. Therefore, when there are many people in a small space such as an office or a bus, it is necessary to frequently exchange indoor polluted air with outdoor fresh air. Air exchange generally adopts a ventilation device.

[0003] Most of the traditional ventilation devices use an exhaust fan to force the indoor air out of the room. However, when the exhaust fan forcibly discharges the indoor air, the cold or hot air in the room is discharged...
