Title: Sealed heat radiating case
Inventor: OHATA MORIYUKI
IPC: H05K7/20
Filed: 1999-11-24
Abstract: PROBLEM TO BE SOLVED: To provide a sealed heat radiating case for an electronic equipment having excellent heat radiating properties. SOLUTION: A black coat film 15 having a thickness of at least 5 μm or more is formed at the inner wall 11a of a sealed metal housing 11. Since the heat ray 16 (indicated by a solid line) radiated toward the inner wall 11a of the housing 11 of the heat radiated from a heating component 12 mounted on a printed board 13 of the electronic component in the housing 11 is absorbed by the film 15 formed on the wall 11a, the temperature of the ray 16 (indicated by a dotted line) reflected and again radiated into the air in the housing 11 is lowered, and hence the air temperature rise amount in the housing 11 by the ray 16 is reduced. That is, the heat of the heating amount of the component 12 by the radiation is efficiently absorbed by the film 15, conducted to the wall 11a of the housing 11 by heat transfer and operated to reduce the reflection of the ray 16.  Since the housing 11 originally has good heat conductivity, the heat absorbed by the film 15 is rapidly externally radiated.
