Heat exchanger turbulizers with interrupted convolutions |
摘要 |
A heat exchanger is disclosed of the type having stacked plate pairs or tubes defining flow passages, with turbulizer located inside such flow passages. The turbulizers are 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 grouped and spaced apart to provide longitudinal neutral zones between groups of adjacent rows of convolutions. The pressure recovery zones and longitudinal neutral channels reduce pressure drop in the heat exchanger without appreciably reducing heat transfer.
