==================================================================
II Next meeting will be on June 24th at the following time
:3:30 - 5:00 PM EST
2:30 - 4:00 PM CST
1:30 - 3:00 PM MST
12:30 - 2:00 PM PST
Will plan to meet for Lunch at ITHERM on Thursday May 28th.
===================================================================
III A. Past Decisions:
a) Need trial standard with by-in from heat sink community
b) Heat sink base to ambient resistance will be reported.
c) Fully ducted test fixture with unform heat sources
- notes will address any deviation and adjustments
d) Test must be reproducible
e) Spec will have two parts - fully ducted and open duct
f) Dimensional data will be used.
B. Issues
a) the following items must be addressed.
- Need to define in detail the spacing between the duct and the heat sink
- Heat losses have to be addressed with non conductive ducting and guarded heaters. Heat flux sensor may be option. Recommend specific materials or define thershold conductivities.
- Limit radiation by defining maximum temperature rise.
- location of heat sink in flow direction
- Limit maximum pressure drop that can be measured
b) Heat source size was discussed again
- If tested other than uniform heating data must define pad size.
c) Velocity, volumetric flowrate or mass flow for independent variable.
d) We need to classify and categorize what heat sinks will be covered by standard.
e) Put together comprehensive list of heat sink vendors
f) Review ASME or other standards.
=================================================================
IV Tasks:
1) Write sections to standard
2) Write notes for Altitude and Temperature adjustment
3) Write notes for non-uniform heat sources
4) Compile list of reviewers
5) Write Reference Test and schematic for benchmarking in notes (Use calibrated heat sink)
6) Set up web site for Adhoc Committee
