Heat exchanger

熱交換器

Abstract

PROBLEM TO BE SOLVED: To provide a heat exchanger in which pressure resistance and heat exchanging efficiency of a heat exchanging tube can be enhanced. SOLUTION: The heat exchanger comprises a heat exchanging tube having inner and outer fluid holes and performs heat exchange between a medium passing through the inner fluid hole and a medium passing through the outer fluid hole wherein the heat exchanging tube 2 has a plurality of outer fluid holes 22, 22 made integrally around the inner fluid hole 21. The heat exchanging tube 2 is made by extruding an aluminum alloy and the wall face of one or both of the inner fluid hole 21 and the outer fluid holes 22, 22 is creased or waved.
