The present invention relates to a heat-exchanging bidirectional ventilator and, more specifically, to a wall-inserted heat-exchanging bidirectional ventilator which can be inserted into a wall and detached from the wall in order to facilitate the maintenance including a work for removing dust deposited inside the ventilator at the same time performing a heat exchange during the influx of the outdoor air and discharging of the indoor air, thus fostering a pleasant indoor environment by smoothly circulating the indoor air. When the wall-inserted heat-exchanging bidirectional ventilator according to the present invention is installed on the outer wall of buildings such as an apartment, a factory, and the likes, the ventilator can be regularly detached from the wall and perform the cleaning of the inside or repair malfunctioning parts, thereby contributing greatly to fostering fresh indoor air. Moreover, since a hood installed on the outer surface of the wall can be installed from the indoor, the installation time and the risk of work can be remarkably reduced. |
