HEAT EXCHANGER FOR A DRIER AND CONDENSING TYPE DRIER UTILIZING THE SAME

摘要

The present invention is open at both ends to flow and circulate the moist air inside the dryer duct of rectangular cross-section in the form of a plurality of tubes and the outside air heat exchanger of the plurality of pin structures are laminated alternately to form the flow , the fin structure and a plurality of air flow passage formed by repeatedly bending a plate-like metal in a staggered way , the air consists of a plurality of fins formed on the surface of the flow path , the pin provides a heat exchanger , characterized in that the dryer is inclined with respect to the protrusion while the surface by cutting a portion of the air flow path surface . According to the present invention , the heat exchange area of the heat exchanger and the heat exchange probability is increased , which can improve the drying efficiency of the dryer adopted , it is possible to lower the manufacturing cost .
