CA 2214255
A heat exchanger is disclosed of the type having stacked plate pairs with a turbulizer located inside each pair of plates. The turbulizer is of the expanded metal type having rows of convolutions. The convolutions are interrupted periodically to form non-convoluted pressure recovery zones located between or downstream of the convolutions. Also, the rows of convolutions can be spaced apart to provide longitudinal neutral zones between the rows of convolutions. The pressure recovery zones and longitudinal neutral channels reduce pressure drop in the heat exchanger without appreciably reducing heat transfer.
