Abstract
A plate fin type heat exchanger capable of developing a performance required for a plate regeneration of a micro gas turbine power generating device, i.e., achieving an increased heat exchanging efficiency and increased durability under violent variation in heat load and formed to have an excellent mass-productivity, wherein all fins are formed inde-pendently of each other for each low-temperature side path without brazing the entire fin inside a high-temperature side path, though all fini in the high temperature side path are non-nally brazed to the low-temperature side path, so as to relieve a thermal stres-s due to nonuniform temperature distribution inside and over the entire surface of a fluid path caused when high-temperature combustion gas flows therein, and the fins in the high-temperature side path are reduced in size and fixed to the low-temperature path side, a small spacer bar is disposed at a portion where the fins are;not provided for the manufacture of core assembling elements, and the elements are laminated, for example, by seal welding the spacer bars to each other so as to extremely facilitate the assembly.
