As defined at the Heidelberg Workshop (April 2013) ( summary): PG advises, simulates. Imperial: engineering design and construction.
  Tasks:
  • Assess and measure heat load
Line: 27 to 27
 
  • The simulation work was paused since mid June, upon completion of the heat load study for the generic end-cap design. The result: 7.5 W per module side. The work will be resumed, once the consensus on the end-cap configuration has been achieved. The intermediate report will be ready shortly.
  • Preparation for the liquid cooling (2-phase) tests is ongoing. The tests will be performed at the TOTEM C3F8-based facility. Mono-phase liquid cooling test setup is being designed (2-stage, with a -10C pre-cooler and a Peltier-based main cooler, down to -50C).
  • Useful links with the industry have been established in May-June: Institute of Thermoelectricity (UA) - specialized Peltier coolers, Thermacore Europe (UK) - low-temperature heat-pipes, composite heat-spreaders.

07 August 2013

  • The work on the air cooling tests continued in July. 4 different options of a cooling pipe have been tested with a full-scale end-cap mockup #1. The compressed air conditioning was upgraded by adding an industrial air dryer. The report is being prepared by the CTU team (expected date: August 10).
Line: 36 to 36
 
  • The liquid cooling (2-phase) test bench at the TOTEM C3F8-based facility has been prepared. The initial measurements, using a special thermostatic enclosure with a controlled thermal load, began this week.
  • Mono-phase liquid cooling test setup will be based on the the FPW-91 Julabo chiller, already delivered, to be installed at Point 8.
  • Negotiations with Thermacore Europe Ltd: an offer to design and manufacture prototype low-temperature ammonia-filled heat-pipes was received. Due to a high price, this option had been put on hold. Solid metal heat spreader with external Peltier chiller is a viable option for a BGV-like module design (discussed with Massi and Fred, TBD with Guido)

04 September 2013

  • 2-phase cooling tests started at the TOTEM test bench at H8, initially with a specially designed isothermal box containing a real cooling pipe (evaporator), a simulation of the end-piece and SiPM array, as well as a heater simulating a heat load of about 10W.
  • Results on temperature uniformity obtained, with different pressure differentials.
Line: 45 to 45
 
  • A smaller new JULABO chiller F81ME/HL, intended for D-module cooling, will be ordered shortly

10 October 2013

  • 2-phase cooling tests continued with the new mockup, completed by September 16.
Changed:

  • Two different insulation wall versions were tested. The total thermal load of the mockup was estimated as ~20W (including the external capillary and loosely insulated connection pipes), by observing the "dry-out" effect at the lowest temperatures at dummy SiPMs (down to -45...-48C). Under these conditions, the C3F8-based system had to be operated with a significant underpressure on the suction side (0.42 bara).

  • The reports about summer tests have been prepared by the CTU group
  • A new round of thermal analysis: evaluation of local parameters of a 2-phase cooling scheme (capillaries, mass flows, thermal cycle)
  • First series of single-phase liquid cooling tests with the (borrowed) Julabo chiller: completed by October 1.
  • Ordered:a JULABO chiller F81HL, intended for D-module cooling; the delivery is expected this week.
  • Preparation of the SiPM cooling workshop of October 17

Status summary:

05 July 2013

 
  • Chilled air cooling lab has been set up. A CTU student is working full-time on the air cooling tests. 4 different options of a cooling pipe will be tested: 3 round tubes with and without inner structures, a rectangular multi-finned radiator (baseline). Currently, the compressed air conditioning is being upgraded.
  • Full-scale mockup of a single end-cap, with 6 cm outer plug and ~13 cm support plate fragment has been constructed. It will be used mostly for the air-cooling tests.
  • The simulation work was paused since mid June, upon completion of the heat load study for the generic end-cap design. The result: 7.5 W per module side. The work will be resumed, once the consensus on the end-cap configuration has been achieved. The intermediate report will be ready shortly.
  • Preparation for the liquid cooling (2-phase) tests is ongoing. The tests will be performed at the TOTEM C3F8-based facility. Mono-phase liquid cooling test setup is being designed (2-stage, with a -10C pre-cooler and a Peltier-based main cooler, down to -50C).
  • Useful links with the industry have been established in May-June: Institute of Thermoelectricity (UA) - specialized Peltier coolers, Thermacore Europe (UK) - low-temperature heat-pipes, composite heat-spreaders.

  • The work on the air cooling tests continued in July. 4 different options of a cooling pipe have been tested with a full-scale end-cap mockup #1. The compressed air conditioning was upgraded by adding an industrial air dryer. The report is being prepared by the CTU team (expected date: August 10).
  • 2nd generation mockup was designed for the upcoming 2-phase cooling tests, using the concept discussed within the end-cap working group. The parts have been made, but not assembled, yet.
Changed:

  • The simulation work is largely completed. The latest end-cap design has an estimated heat load of 5.7W per module side. In addition, promising results were obtained for "the cooling-though-flexPCB" option (to be discussed with the SiPM community). The summary report is under preparation.

  • The liquid cooling (2-phase) test bench at the TOTEM C3F8-based facility has been prepared. The initial measurements, using a special thermostatic enclosure with a controlled thermal load, began this week.
  • Mono-phase liquid cooling test setup will be based on the the FPW-91 Julabo chiller, already delivered, to be installed at Point 8.
  • Negotiations with Thermacore Europe Ltd: an offer to design and manufacture prototype low-temperature ammonia-filled heat-pipes was received. Due to a high price, this option had been put on hold. Solid metal heat spreader with external Peltier chiller is a viable option for a BGV-like module design (discussed with Massi and Fred, TBD with Guido)

  • Results on temperature uniformity obtained, with different pressure differentials.
  • 2nd generation mockup , implementing the end-cap concept adopted in July, has been constructed and installed at the H8.
  • The JULABO chiller for single-phase liquid tests installed at Point 8, in the 2885/2-201 lab
  • A smaller new JULABO chiller F81ME/HL, intended for D-module cooling, will be ordered shortly

  • 2-phase cooling tests continued with the new mockup, completed by September 16.
Changed:

  • Two different insulation wall versions were tested. The total thermal load of the mockup was estimated as ~20W (including the external capillary and loosely insulated connection pipes), by observing the "dry-out" effect at the lowest temperatures at dummy SiPMs (down to -45...-48C). Under these conditions, the C3F8-based system had to be operated with a significant underpressure on the suction side (0.42 bara).

  • The reports about summer tests have been prepared by the CTU group
  • A new round of thermal analysis: evaluation of local parameters of a 2-phase cooling scheme (capillaries, mass flows, thermal cycle)
  • First series of single-phase liquid cooling tests with the (borrowed) Julabo chiller: completed by October 1.

A CFD simulation Project Proposal (link to EDMS document). This project, joint with EN/CV, was intended to evaluate the heat load of the FT module end caps and give some insight for various prospective cooling options. Author: Enrico da Riva (CERN, EN/CV/PR).

  • 2013-08-01: Addendum to 22/07: cooling through flex PCB.
  • 24/07/2013: latest end cap simulation results ("July" geometry). 5.7 W/module
  • 2013-06-10: 3D with Alu + edge insulation; multiport cooling pipe. 7.1 W/module
  • 2013-05-30: Alu jacket; liquid and air cooling estimates. 7.1 W/module
  • 2013-05-27a: First 3D results, more on liquid coolants. 3D≈2D
  • 2013-05-14: End caprefinements, liquid_coolants. 6.3...8.5 W/module
  • 2013-04-22: 2nd_round results: try to minimize the heat load. ~6 W/module
  • 2013-03-13: 1st round results: heat load with a simplified geometry. ~10 W/module
Bottom line: in the ideal case (with no inlet/outlet tubes, perfect thermal contacts) the heat load per module should be less than 10W. The T drop between the cooling pipe and the Si die strongly depends on the stiffener material. For FR4: ~7 (~5.7 W/module); for carbon: ~3 (~6.3 W/module)

Status summary: 10 October 2013

  • 2-phase cooling tests continued with the new mockup, completed by September 16.
  • Two different insulation wall versions were tested. The total thermal load of the mockup was estimated as ~20W (including the external capillary and loosely insulated connection pipes), by observing the "dry-out" effect at the lowest temperatures at dummy SiPMs (down to -45...-48C). Under these conditions, the C3F8-based system had to be operated with a significant underpressure on the suction side (0.42 bara).
  • The reports about summer tests have been prepared by the CTU group
  • A new round of thermal analysis: evaluation of local parameters of a 2-phase cooling scheme (capillaries, mass flows, thermal cycle)
  • First series of single-phase liquid cooling tests with the (borrowed) Julabo chiller: completed by October 1.
  • Ordered:a JULABO chiller F81HL, intended for D-module cooling; the delivery is expected this week.
  • Preparation of the SiPM cooling workshop of October 17

Status summary: 07 August 2013

  • The work on the air cooling tests continued in July. 4 different options of a cooling pipe have been tested with a full-scale end-cap mockup #1. The compressed air conditioning was upgraded by adding an industrial air dryer. The report is being prepared by the CTU team (expected date: August 10).
  • 2nd generation mockup was designed for the upcoming 2-phase cooling tests, using the concept discussed within the end-cap working group. The parts have been made, but not assembled, yet.
  • The simulation work is largely completed. The latest end-cap design has an estimated heat load of 5.7W per module side. In addition, promising results were obtained for "the cooling-though-flexPCB" option (to be discussed with the SiPM community). The summary report is under preparation.
  • The liquid cooling (2-phase) test bench at the TOTEM C3F8-based facility has been prepared. The initial measurements, using a special thermostatic enclosure with a controlled thermal load, began this week.
  • Mono-phase liquid cooling test setup will be based on the the FPW-91 Julabo chiller, already delivered, to be installed at Point 8.

Status summary: 05 July 2013

  • Chilled air cooling lab has been set up. A CTU student is working full-time on the air cooling tests. 4 different options of a cooling pipe will be tested: 3 round tubes with and without inner structures, a rectangular multi-finned radiator (baseline). Currently, the compressed air conditioning is being upgraded.
  • Full-scale mockup of a single end-cap, with 6 cm outer plug and ~13 cm support plate fragment has been constructed. It will be used mostly for the air-cooling tests.
  • The simulation work was paused since mid June, upon completion of the heat load study for the generic end-cap design. The result: 7.5 W per module side. The work will be resumed, once the consensus on the end-cap configuration has been achieved. The intermediate report will be ready shortly.
  • Preparation for the liquid cooling (2-phase) tests is ongoing. The tests will be performed at the TOTEM C3F8-based facility. Mono-phase liquid cooling test setup is being designed (2-stage, with a -10C pre-cooler and a Peltier-based main cooler, down to -50C).
  • Useful links with the industry have been established in May-June: Institute of Thermoelectricity (UA) - specialized Peltier coolers, Thermacore Europe (UK) - low-temperature heat-pipes, composite heat-spreaders.
