Title:
HEAT EXCHANGER
Document Type and Number:
WIPO Patent Application WO/2014/175158
Kind Code:
A1
Abstract:
 A heat exchanger (1) in which a gas passage (20A) is provided with a forward-tilting protruding piece (25A) disposed at a forward tilt angle (α1) so as to lean forward toward the upstream side with respect to the direction of gas flow, and a rearward-tilting protruding piece (25B) disposed downstream of the forward-tilting protruding piece (25A) at a rearward tilt angle (α2) so as to lean rearward toward the downstream side with respect to the direction of gas flow. The forward-tilting protruding piece (25A) is a polygon having four or more sides, and has: a bottom side (26A) in contact with the peripheral surface of the gas passage (20A); and a pair of left and right lateral sides (27A, 28A). The bottom side (26A) is disposed at an installation angle (β1) so as to be oriented diagonally with respect to the direction perpendicular to the direction of gas flow. The angle (a) of one of the lateral sides (27A), located upstream with respect to the direction of gas flow, with respect to the bottom side (26A) is greater than the angle (b) of the other lateral side (28A), located downstream with respect to the direction of gas flow, with respect to the bottom side (26A).
