The invention provides a new blower exchanger core using plastic wave model strips which belongs to the general heat exchange accessory part technique field and comprises a cubic column new blower frame, pre and post end covers, a plastic wave model strip frame group and a thermal mass exchange material group, wherein the thermal mass exchange material has a paper sheet shape, the new blower frame and the pre and post end covers, the model strip frame and the thermal mass exchange material are spacedly arranged, the model strip frame is formed by a frame and the model strips which are equidistantly arranged, the adjacent model strip frames are arranged with the model strip direction vertical to each other, the frame model strips are equidistant plane plastic wave model strips having the same shapes, the model strip is equipped with a guide vane which is paired set left and right symmetrically on the model strip. The new blower exchanger core using the plastic wave model strip has advantages that: the material is plastic sectional material with extreme durability structure and convenient processing, the special structure design of the plastic wave model strip frame allows air to flow along a curve in a channel, thereby lengthening the total course, increasing the thermal mass exchanging time and facilitating to increase exchanging efficiency.
