METHOD OF OPERATION OF HEAT EXCHANGER AND HEAT EXCHANGE DEVICE Russian patent published in 1995 - IPC

FIELD: heat engineering. SUBSTANCE: heat exchange device has heat exchange members arranged in heat exchanger and source of high frequency oscillations arranged outside. Grid installed in housing is connected to source of high frequency oscillations. Fitted in holes of grid with clearance are members with support beads engaging with hole through their side surfaces arranged at angle to member surface. Grid has projections uniformly spaced over perimeter and engaging with source of oscillations. In process of operation heat carrier is pumped through heat exchange member and space between members at simultaneous exposure to high frequency oscillations from source applied at angle to side surfaces of heat exchange members. This provides unidirectional elastic deformation travelling surface waves with vertical polarization which ensure pumping through of heat carrier. EFFECT: enhanced efficiency of operation. 2 cl, 2 dwg
