PROTECTIVE COVER AND SEMICONDUCTOR DEVICE THEREWITH

摘要

PROBLEM TO BE SOLVED: To provide a protective cover that can suppress the temperature rise of a component or semiconductor device to a low level by efficiently radiating the heat generated from the component to the outside and can be reduced in the number of used members. SOLUTION: This protective cover 21 has side plate sections 23 and 25 facing a substrate 13 on which a component 11 is mounted. The side plate sections 23 and 25 have directed plate sections 41 and 43 (143 or 241) which discharge an air flow B which is produced from an air flow A introduced into spaces between the side plate sections 23 and 25 and substrate 13 after the air flow A cools the component 11 to the outside of the sections 23 and 25. The directed plate sections 41 and 43 (143 or 241) confront the air flow A or B. In addition, this protective cover 21 has window sections 31 and 33 (131) through which the air flow A is taken in or the air flow B is discharged. COPYRIGHT: (C)2004,JPO
