Title: Size enlarging and heat transfer promoting methods for plate fins of laminated heat exchanger
Inventor: KISHINAMI KOKI
IPC: F28F3/06
Filed: 2002-04-10
Abstract: <P>PROBLEM TO BE SOLVED: To establish a structure capable of producing a turbulent flow and a stratified flow continuously inside a laminate structure using insert plates and rows of fins.  <P>SOLUTION: The structure of a heat exchanger according to the invention is such that insert plates 3 having a height 50-60% of plate fins 2 for low temperature fluid are installed in the middle 8 between each row of plate fins and a space 8 while insert plates 3 having a height 50-60% of plate fins 7 for high temperature fluid are installed in the middle 8 between each row of these plate fins 7 and a space 8 through each heat conductive partitioning plate 5, and they are laid one over another in the directions intersecting perpendicularly. The low temperature air and the high temperature air undergo a heat exchange by the heat passage action through the heat conductive partitioning plates 5, when the insert plates and the rows of fins can produce the turbulent flow and stratified flow continuously because the arrangement is able to preclude production of a thick temperature boundary layer and a pressure loss on the air side, thereby the coefficient of heat transfer is improved and the heat exchange efficiency as a whole can be enhanced. Thereby the size of the plate fins can be enlarged and the heat transfer be promoted to enable flowing-through of the air containing much impurities, and the resultant heat exchanger is unlikely to generate clogging even if impurities are attached to its bulkhead.  <P>COPYRIGHT: (C)2004,JPO
