Abstract
To provide a plate laminate type heat exchanger that is capable to be temporarily fixed easily and surely before brazing assembly and can be fabricated with good accuracy. In a plate laminate type heat exchanger using a cladding material cladded with a brazing material, in each of laminated plates, a round hole penetrating in a laminate direction is formed; a thin and long fixing pin is inserted into the round hole so as to communicate each of plates; the fixing pin is fixed to the round hole by expansion of the outer diameter only at one end part in the longitudinal direction of the fixing pin; and each of plates is temporarily fixed integrally.
