Inner fin of heat exchanger

Abstract

Abstract PURPOSE:To improve heat exchanging efficiency and restrict pressure loss by a method wherein the pitch, the height and the ratio of segmental length to the pitch of the inner fin, accommodated in the flow path of fluid, are determined so as to be in specified relations in the heat exchanger for a supercharger. CONSTITUTION:An intercooler for the supercharger is formed by a method wherein the plates 1, made of aluminum, are bonded and the flow path 2 of fluid is formed in the set of bonded aluminum plates 1 while the set of plates 1 are piled sequentially while arranging a fin 3 between the sets of the plates 1. The inner fin 8 of rectangular waveform is inserted into the flow path 2 of fluid so that walls 8a are arranged in parallel to the flow of supercharging air while the inner fin is designed so that relations of 3<=P<=7mm, 3<=B<=6mm and 0<2L/P<=3 are kept in the fin pitch P, the height B of fin and the segmental length L of the fin and the inner fins are bonded to the plates 1 by brazing. Thus, the heat exchanging rate between gasses may be improved and the pressure loss may be minimized without changing the profile dimension or the shape of the heat exchanger.
