A counter flow type heat exchanger is provided to improve heat exchange efficiency by forming a corrugate feature at the center of a heat exchange plate for increasing a contact area. A counter flow type heat exchanger comprises heat exchange plates(20) and support frames(30). The support frames consist of a pair of support bars, a pair of support bars(36), closed support bars(40-1), edge connection holes(50), a corrugate feature, and a long bolt(13) and a nut(14). The support bars are crossed with closed bars(40-2) wherein gas holes are bored at regular intervals. The support bars are opposed to the closed support bars at the outside of the support bars and have gas holes(37) penetrated at regular intervals. The closed support bars are continuously installed between each support bars. The edge connection ports couple the support bars with an end of the closed support bars. The corrugate feature is formed at the center of the heat exchange plate. The long blot and the nut assemble each edge of the heat exchange plate and the support frame. |
