換器。 A box-shaped case houses a heat transfer unit in which a number of heat transfer partition walls are arranged side by side at predetermined intervals to form multiple flow paths, and forced convection fans inside and outside the control panel installed above and below the unit. The upper and lower end surfaces of the flow path are alternately and airtightly sealed, and air inside the control panel and air outside the control panel are alternately forced to convect within the flow path of the heat transfer unit to exchange heat through the heat transfer partition wall. In the heat exchanger, a deflection plate is disposed in close contact with the end of the heat transfer unit and has an inclined surface facing from the convection fan mounting surface side of each convection fan inner surface to the suction surface of the convection fan, A heat exchanger for a control panel, characterized in that a porous sound-absorbing sheet is attached to cover the inclined surface of the deflection plate and its suction side edge.
