RADIATOR AND ITS PRODUCING PROCESS

摘要

PROBLEM TO BE SOLVED: To reduce the weight while enhancing machinability and to attain a sufficient strength while preventing warp. SOLUTION: The radiator 16 has a metallic main component 17 provided with a filler 18 having a low thermal expansion coefficient. The main component 17 is formed of a so-called high heat conducting material having a high thermal conductivity, e.g. Cu or a Cu alloy. The filler 18 is a linear body having an appropriate size formed of a metal, e.g. Invar alloy, having a thermal expansion coefficient smaller than that of the main component 17 integrally with the main component 17. The filler 18 is oriented to a specified direction on a plane when the radiator 16 is formed. COPYRIGHT: (C)2004,JPO&NCIPI
