<p>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/or inert gas atmosphere; and a production method therefor; the deterioration of titanium composition members in a heat exchanger due to high-temperature heating at brazing being prevented.</p> |
