PURPOSE:To obtain heat exchange devices capable of reducing the height of a ventilation device. CONSTITUTION:There are installed ribs 3 and 4 which shield the side, and ribs 5 and 6 which shield half the end on one side of a sheet 2. This heat exchange device is constituted by laminating a block 1A which forms a flow inlet 7 of a primary air flow A flowing on the slant and an outlet 8 and a block 1B which forms a flow inlet 10 of a secondary air flow flowing on the slant and an outlet 11 with flow passages 3a, 4a, 5a and 6a. |
