Abstract
Abstract A system is disclosed for use in packaging electronic systems for use in high temperature well boreholes. A fluid tight hollow body member or sonde is provided having unique longitudinally extensive hollow support and mounting members for electronic components. The hollow interior of the support and mounting members contain a bismuth eutectic alloy heat absorbant material for evenly distributing heat developed in the electronic componentry throughout the logging tool.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
95 words
Well logging apparatus for use in high temperature boreholes in earth formations, comprising: a fluid tight hollow body member sized and adapted for passage through a well borehole, said body member housing interiorly thereto a longitudinally extensive support and mounting member for mounting electrical components thereon, said support and mounting member having a hollow interior construction and containing a heat absorbant material approximately uniformly distributed along its longitudinal length, thereby providing an approximately uniform heat absorbing capability along the length of said support and mounting member for absorbing heat from electrical components in said apparatus.
Claim 2
Dependent Claim
95 words
Well logging apparatus for use in high temperature boreholes in earth formations, comprising: a fluid tight hollow body member sized and adapted for passage through a well borehole, said body member housing interiorly thereto a longitudinally extensive support and mounting member for mounting electrical components thereon, said support and mounting member having a hollow interior construction and containing a heat absorbant material approximately uniformly distributed along its longitudinal length, thereby providing an approximately uniform heat absorbing capability along the length of said support and mounting member for absorbing heat from electrical components in said apparatus.
