<p><P>PROBLEM TO BE SOLVED: To reduce the number of parts, improve sealability without using a sealing material, and manufacture a part at a low cost. <P>SOLUTION: An air supply path 12 and an air exhaust path 13 are formed from metal plates, and bent portions 17 of a blowout pipe 14, an air supply side air path forming plate 15, and an exhaust side air path forming plate 16 composing the metal plates are provided with perforation-like hit marks. The bent portions 17 are formed by bending along a hit mark line 18 formed by the gouges. As one part having a complicated shape can be formed by bending with the hands without a manufacturing facility, the heat exchanger air path forming plate with a reduced number of parts and capable of securing sealability can be provided. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
