<P>PROBLEM TO BE SOLVED: To provide a corrugated fin type heat exchanger which prevents flow rate reduction at an inflow end of an air flow and flow rate reduction on a downstream side of a turning louver, and improves heat exchange performance. <P>SOLUTION: An inlet flat part 2, an intermediate flat part 3, and an outlet flat part 4 without a louver are formed on a surface of a fin. A width L<SB POS="POST">4</SB>of an outlet louver is formed to be approximately half of a width L of a normal louver 1, and a width L<SB POS="POST">1</SB>of an inlet louver 5 and a width L<SB POS="POST">3</SB>of a second turning louver 7 are wider than the half of the width L of the normal louver 1. <P>COPYRIGHT: (C)2013,JPO&INPIT |
