A method of producing a heat exchanger, comprising: obtaining a titanium plate (201) that has been cladded with a melting depressant foil (208), and heat treated for improving ductile properties; pressing a pattern in the titanium plate (201); stacking the titanium plate (201) on a number of similar titanium plates (201, 401); heating the stack of titanium plates to a temperature above 850 ºC and below the melting point of titanium, the melting depressant foil (208) causing surface layers (214) of the titanium plates (201, 401) to melt and flow to contact points (240) between adjacent titanium plates (201, 401); and allowing the melted titanium to solidify, such that joints (241) are obtained at the contact points (240) between adjacent titanium plates (201, 401). |
