PURPOSE:To obtain a heat exchanger which is manufactured easily and having good humidity exchanging efficiency so as to be able to measure simply the increase of the ventilating resistance by a method wherein the plurality of unit members provided the plurality of ribs line are put by lamination to the one side of a flat board type plate. CONSTITUTION:The heat exchanger 1 is formed by many parallel flowing path due to the straight line ribs 3 arranged by equal intervals for a fixed direction at the respective spaces of the plurality of the plates 2 and the direction of the ribs 3 has a gap about 90 deg. for every lamination. Two of the both end parts among the ribs 3 of the unit member 4 and one of the center part at the upper surface 5 is formed on wider than the surface of other many ribs 3B and the improvement of adhesion and integrity for the fellow plate 2 is designed in case the unit member 4 is put by lamination. Many other ribs 3 are consisted of pipes, round bars and square bars having a narrow spot surface for the plate 2 whereby it is constituted so as to narrow the parallel flowing path and make large the ventilating resistance and may be adhered to the plate 2. |
