Abstract
A plate tube type heat exchanger using porous fins is manufactured of foamed metal. The porous fins used for the plate tube type heat exchanger are formed of a foamed metal such as aluminum or copper having a high thermal conductivity. The plate tube type heat exchanger using such porous fins exhibits an excellent heat transfer capability, compared to a conventional plate tube type heat exchanger using louvered fins, thereby simplifying production steps and realizing an excellent structural rigidity.
Claims2
In a plate tube heat exchanger provided with a fluid path inlet, an inlet tank, a plate tube, a plurality of fins, a tank, and a fluid path outlet, the improvement wherein the plurality of fins are porous and formed of a foamed metal with a porosity of more than 88%, a pore density of less than 40 ppi, and a thermal conductivity of more than 100 W/mK.
