AB - INVESTIGATIONS AND CALCULATIONS OF THERMOPHYSICAL PROCESSES HEAT EXCHANGE AND HYDRAULIC RESISTANCE IN PERFORATED-PLATE HEAT EXCHANGERS V. K. Orlov, S. A. Shevyakova, UDC 66.045.1:[532.5 + 536.24].001.5 and G. N. valeev Perforated-plate heat exchangers are characterized by a high surface-to-volume ratio (1500-2500 m2/m 3) and efficient heat exchange. The perforated-plate heat exchangers consist of parallel metal perforated plates of a heat-conducting material (copper or aluminum) separated by spacers. The heat exchange elements are bonded together. The adhesive layers between the elements significantly decrease the detrimental effects on the equipment efficiency of longitudinal heat conduction in its structural elements. As the results indicate, for the investigation of models of double-flow heat exchange recovery units with perforated plates [1], heat exchange and hydraulic resistance is significantly affected by the geometry of the heat exchange surface. It is only possible to establish these relationships experimentally. We studied heat exchange and hydraulic resistance in heat exchangers with perforated plates with holes 0.9 mm in diameter spaced 1.4 mm apart in a rectangular array. Three experimental models were studied. They differed in the spacing between the perforated plates and the height of the heat exchanger, with the follow- ing basic geometric and design characteristics: 0.50 Thickness
