Title: Semiconductor device and its cooling method
Inventor: NAGANUMA YOSHIO
IPC: H05K7/20
Filed: 1988-09-14
Abstract: PURPOSE:To provide possibility of cooling with low level of noises or without the same by cooling the heat emitting parts elsewhere than high heat emitting part of a semiconductor device consisting of an aggregate of electronic parts by means of forced convexion through utilization of the liquid stream, which is generated in linkage with natural convexion to be produced at the high heat emitting part. CONSTITUTION:Semiconductor devices are installed on three boards 2 with their respective heat resistances taken into consideration, wherein an LSI 4 for cooling having the least heat resistance is situated below the board 2 while a one 6 having heat resistance comparatively above the board 2. A resistance heat radialing body 8 is arranged in a heat emitting part which brings about natural convexion, and the ambient air is heated. The density of this heated air becomes smaller, and the air produces natural convexion as a heated fluid 10. As a result, the air below the boards 2 rises along them to cause introduction of the fluid to be heated 12 along the boards 2 from outside anew, and a standing flow along the boards 2 is formed. Thus calm cooling of semiconductors is accomplished through utilization of the fluid stream due to natural convexion.
