Device for fixation of door on HVAC for automobile

摘要

The present invention relates to a door fixation apparatus for a vehicle air conditioner that is capable of preventing various doors or dampers that are installed in an air conditioner from partially opening due to wind pressure when a vehicle is operating or an air conditioner is operated in a state that the doors or dampers are closed. The door fixation apparatus includes a magnetic body that forms at least part of a ventilation opening and closing of the door of the vehicle air conditioner; an electromagnet that is installed adjacent a ventilation opening so that at least part of the magnetic body of the door is magnetically adhered to the electromagnet in a blocking position of the ventilation opening; a power source that supplies the current for magnetizing the electromagnet; and a controller to judge the opening and closing state of the ventilation opening and control a current supply of the power source.
