Abstract
A heat conductive composite made compact plate shell type heat exchanger comprises a housing, an element and a seal plate with the element composed of barricades, fins of metal and anti-erosion heat conductive composite ones alternatively set between two adjacent barricades, and a seal which is set between the anti-erosion heat conductive composite fines and housings. With metal fins and anti-erosion fins located alternatively, the former going through relative clean media and the latter going through the corrosive and easily scaled media, it has ensured highly efficient heat exchange by the two media forming a completely counter flow heat exchanging effect. Using the glued barricade structure on the long opening seal board, changing regular fluoroplastic shell type exchange tube bundle, different from plate or plate-fin heat exchanger, it has high heat exchange efficiency, good anti-erosion performance, rigid structure, and high bearing capacity.
