Abstract

PURPOSE: To decrease the steps of processing and also, to manufacture the above- mentioned heat exchanger excellent in heat exchanging characteristic, by expanding a hollow tube and making the contact of the outer wall face with fin good and at the same time, making the inner wall of the hollow tube rough.
CONSTITUTION: Pipe expanding apparatus is prepared connecting with the ball 20 formed the innumerable projections 7 on the surface or combination of the above ball 20 and the smooth ball 5 by the rod 6. Next, the above-mentioned apparatus is drawn out from the hollow pipe 2 by drawing the rod 6 in the arrow mark direction A from the pipe 2. As a result of it, contact of the pipe 2 and the fin 1 is made good by expanding the pipe 2 by the pipe expanding apparatus and at the same time, the inner wall face of the pipe 2 is made rough. That is, heat transmission area is increased by making the inner wall face of the pipe 2 rough and plate fin tube heat exchanger excellent in heat exchanging characteristic, is obtained.
