Heat exchanger with plate-formed flowpath has bellied sector reaching into flow path and composed of bulged and ovalized cylinders abutting flatsheets to complete flow path sector.

摘要

A bellied sector projecting into the coolant flow path consists of two bulged sheets and a number of ovalized cylinder sectors with their large diameter in the flow direction. Between the two sheets are two further flat sheets arranged so the upper part of the bellied sector abuts the opposing flat sheet, with the number of ovalized sectors decreasing in the flow direction. The inside flow path (R) for the coolant is formed by laminating two flat-drawn sheets (13,14) to form the flow path sector (11) and alternately laminating the coolant rib (12). The two flat sheets contain coolant inlet (15) and outlet (16). The cylindrically ovalized sectors are diagonally adjacent so as to overlap in the flow path.
