HEAT INSULATOR INTEGRAL TYPE ALUMINUM DIE CASTING CASE

摘要

PROBLEM TO BE SOLVED: To provide an aluminum die casting case for housing a heating component which has a good heat sink efficiency with an easy constitution and in which a mutual heat interference of individual heating components can be suppressed. SOLUTION: The aluminum die casting case 10 comprises a heat insulator 14 made of the same material as that of the case 10 and integrally formed with the case 10 so as to suppress heat transfers between inverters 12a and 12b as heating components housed in the body 10a of the case 10 and to upgrade the heat sink. The insulator 14 is formed on the rear surface side (the inner wall of the body 10a) of heat sink fins 10c formed on the one surface of the outer wall of the case 10. As a result, the aluminum die casting case for housing the heating component in which the mutual heat interference can be preferably suppressed with a simple constitution and the heat can be dissipated, can be obtained.
