发明名称 PRODUCTION OF HEAT EXCHANGING ELEMENT
摘要 PURPOSE:To economize the amt. of the solder or brazing material to be used and to produce a heat exchanging element having a lighter weight by forming a solder/brazing material layer on the part to be joined of a pipe member or fin member and joining both members via said layer. CONSTITUTION:A solder/brazing material layer 18 is formed to a prescribed thickness by spraying of the droplets of a solder or brazing material to the part to be joined on the outside circumferential surface of a heat exchanging pipe 2 which is a pipe member consisting of a flat perforated pipe having plural fluid passage holes 1 in parallel with each other in one row. A heat radiating fin 10 consisting of only the core material 4 is combined between a pair of the heat exchanging pipes 2 formed in such a way and these members are joined by a brazing method in furnace. The above-mentioned layer 18 is thus melted to form a brazing part 16, by which the lightweight heat exchanging element is efficiently formed with a small amt. of the solder or brazing material.
