Document Type and Number:
Japanese Patent JP2010117101
Kind Code:
A
Abstract:
To reduce pressure loss while suppressing degradation of heat exchanging performance.
A plurality of heat transfer plates 100 formed into the corrugated shape of projections 7a and recesses 7b having a prescribed angle to a central line 50 are prepared, and alternately stacked so that the directions by the angles of the corrugated shape are opposite to each other, and joining sections 80 where the corrugated shapes are intersected and kept into contact with each other are joined by brazing.
