Patent abstract
A heat exchanger of a ventilating system, including heat exchange plates which are laminated at a predetermined interval and divide an outdoor air path through which outdoor air passes and an indoor air path through which indoor air passes, and a plurality of embossing protrusions which are formed on the outdoor air path divided by the heat exchange plates, for generating turbulence in the outdoor air which flows in the outdoor air path, can improve heat transfer performance by controlling development of a boundary layer by differentiating structure of the air flow of an air path through which indoor air passes and an air path through which outdoor air passes.
