The invention provides a plate bundle of a plate-fin heat exchanger, a machining method of the plate bundle and the plate-fin heat exchanger, and belongs to the technical field of heat exchange equipment. The plate bundle of the plate-fin heat exchanger is suitable for being machined through a dispersion welding mode, and comprises a fin being a plate with multiple bends, at least two separation plates being of flat plate structures and covering the top surface and the bottom surface of the fin, and sealing strips parallel to a channel formed by the fin and the separation plates and arranged at two ends of the fin; the upper and lower surfaces of the sealing strips are connected with the separation plates; and the sealing strips are thinner than or as thick as the fin. In the plate bundleof the plate-fin heat exchanger, as the sealing strips are thinner than or as thick as the fin, the excellent stable connection between the fin and the separation plates can be guaranteed during dispersion welding, and the pl
