NONMETAL CORROSION-RESISTANT HEAT EXCHANGE DEVICE AND PLATE-TYPE HEAT EXCHANGER HAVING SAME

摘要

A high efficiency non-metallic corrosion resistant heat exchange device and a plate-type heat exchanger with the same are provided. The heat exchange device includes multiple non-metallic corrosion resistant heat conduct plates, upper supporting ribs disposed on a top surface of each heat conduct plate, lower supporting ribs disposed on a bottom surface of each heat conduct plate, sealing strips disposed on upper edges of the top surface and lower edges of the bottom surface of each heat conduct plate, and spacers. The upper and lower supporting ribs and the sealing strips are fixed on the corresponding heat conduct plate. The spacers are arranged between the lower supporting ribs of an odd number heat conduct plate and the corresponding upper supporting ribs of an even number heat conduct plate. The spacers are also arranged between the sealing strips of a bottom surface of the odd number heat conduct plate and the corresponding sealing strips of a top surface of the even number heat conduct plate. The adjacent upper and lower supporting ribs located between the adjacent odd and even number heat conduct plates together define multiple sealing channels, which can be used as cold fluid channels and hot fluid channels. These sealing channels have different shapes and directions and are not communicated with each other. The spacers are used to completely seal the corresponding upper and lower supporting ribs and the corresponding sealing strips by a press force.
