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.

摘要: A mounting or end bracket is disclosed for producing plate and fin heat exchangers of the type having a plurality of stacked, hollow plate pairs or tubes including mating end bosses having communicating openings formed therein to form a manifold for the flow of fluid through the plate pairs or tubes. Fins are located between and at the top end bottom of the stacked plate pairs or tubes extending between the end bosses. End fittings are used for the inlet and outlet of fluid to the plate pairs or tubes. The mounting brackets allow the end fittings to be positioned where desired to define different flow circuits through the plate pairs, and also allow different size end fittings to be used, without having to use special spacers, different size fins or specially shaped plates to accommodate the different end fittings. The mounting brackets have a planar central portion and opposed offset end portions located in a plane parallel to and spaced from the central portion. The central portion has spacing projections extending transversely in a direction opposite to that of the opposite end portions. Different fitting sizes are accommodated simply by changing the height of the spacing projections.
