A heat exchanger for a ventilating apparatus is provided to enhance heat transfer efficiency by securing a straight air passage between heat exchange layers, and to increase durability of the heat exchanger by preventing drooping of the heat exchange layer. A heat exchanger for a ventilating apparatus comprises a heat exchange layer(211,221), a plurality of air supply guide ribs(212), and a plurality of discharge guide ribs(222). The air supply guide ribs are arranged on one side of the heat exchange layer. The exhaust guide ribs are arranged on the other side of the heat exchange layer. A center portion of the air supply guide rib and a center portion of the exhaust guide rib are disposed on different lines. |
