Title:

TITANIUM−MADE PLATE−TYPE HEAT EXCHANGER AND PRODUCTION METHOD THEREFOR

Document Type and Number:

WIPO Patent Application WO/2003/089866

Kind Code:

A1

Abstract:

A titanium−made plate−type heat exchanger characterized in that, when forming, by joining titanium−made composition members, flow paths in a heat exchanger having first−fluid flow paths and second−fluid flow paths arranged alternately to effect heat exchanging between the two fluids, a Ti−Zr based brazing filler metal containing 20−40 wt.% of Ti and 20−40 wt.% of Zr and being melted at up to 880°C is applied to the joint portions of respective composition members, and they are heated at up to 880°C in vacuum and&sol or inert gas atmosphere&semi and a production method therefor&semi the deterioration of titanium composition members in a heat exchanger due to high−temperature heating at brazing being prevented.
