- Heat pipe bending constraint (as recommended by
the HP manufacturer) has been implemented - Radiator heater lay-out (two different sets) has
been confirmed - J electronics Switch-on sequence analyzed and
verified - JPD Close-On-Rise thermostats set-point selected
(-25C/-19C) - JPD Close-On-Rise thermostat position depending
on TVT results on first J/JT/JPD set

25Main radiator (WAKE) thermal design status
- Heat pipe bending constraint (as recommended by
the HP manufacturer) has been implemented - PDS mass saving guidelines implemented
- Embedded heat pipe cold-plate has been replaced
by a smarter heat pipe layout - Final heat pipe layout on-going
- First set of 3-D heat pipes (not affected by the
heat pipe re-arrangement) ready to be sent to
pipe manufacturer

36WAKE RADIATOR
37WAKE RADIATOR STATUS
- First issue for INNER SKINS and OUTER SKINS
drawings delivered on 20.04.07. - To be implemented
- I/F holes for white paint protection panels on
outer skins - I/F holes to cab lhp on outer skins
- I/F holes to TB and Thermostats on inner skins

42Changes to the FM design (1)
- After STA integration
- MID brackets length has been reduced by 2mm
43Changes to the FM design (2)
- PANEL cut-out reduced by 3mm
- for MID-BRACKETS (both radiators)
- CAB mounting bolts on lower side of box ( only
WAKE)
44CAB 2 phase model
- Gongming Xin (SDU)
- Stefano Zinna (UniBG)
45CAB LHP 2 Phases Modeling
- Cases needed to run
- Steady State of CAB in Worst Hot Case (105W)
- Steady State of CAB in Worst Cold Case (35.5W)
- CAB Ramp-UP process
- In different CAB/LHP mode
- CAB
- Ramp Up nominal mode (6 CCS CS)
- Ramp Up module failure mode (5 CCS CS)
- LHP
- Nominal mode (2 LHPs working)
- Failure mode (1 LHP failure)
46- Modeling start with
- SINDA/FLUINT
- parameters based on the preliminary design of CAB
LHP - One LHP working (Failure mode of LHP) in the
beginning.
CAB
LHP Condenser Layout on the Wake Radiator
47Characteristics of 2 phases model (1 LHP)
- Working fluid--Ammonia
- 4446 thermal nodes, 42 fluid lumps
- Conductance to radiator 800(W/m2/K)Area
- Conductance from Eva-Saddle to CAB Baseplate
1000(W/m2/K)Area
- Evaporator model shown as below
48Status
- The modeling has been completed with
- Parametric analysis done for some critical
parameters (e.g. power, heat transfer coefficient
in wick-Uw, Back conductance-Uback, and the ratio
of Uw/Uback) - Model running for one LHP in both worst hot and
worst cold cases for CAB - Results achieved for both cases, but need to be
reviewed. - Ramp-Up process (LHP failure mode) ready to run
once the model is validated.
49Heaters and thermostats procurement
50Thermostats (19 for the EHV, 5 for the Ecrate
and 10 for the RHV)
- Two options
- US source 18 weeks lead time export license
- E.G. 12 weeks for ECAL thermostats
- E.G. 16 weeks for ECAL thermostats intermediate
consignee change (to allow installation in
Annecy) - European source 26 weeks, no license required
51Thermostats
- Procurement started, on the basis of verbal
agreement with INFN PI (F. Cervelli and M.
Incagli) on 26th March 2007 - J. Berdugo statement at JSC we will follow
Franco CERVELLI, who else? taken literally - RHV thermostats ordered as well
- Paperwork (proposals from CGS to INFN and
CIEMAT) still ongoing as per today (NO PROBLEM,
provided we get the purchase order) - 5 thermostats (on stock) for E-crates expected
within 4 weeks (End of May 2007) - All the others 29 Thermostats expected for
September 24th
52Heaters
- 11 weeks lead time
- Expected delivery June 15th, 2007
