Comparative Study of 60µm Filter Efficiency and Thermosiphon Results in Cooling System Testing

This study involves characterization of 60µm filters and comparison with thermosiphon results in a cooling system setup. Evaluation of pressure drop, flow rate, and error range will be conducted, followed by tests to assess variations in the filters, capillaries pressure drop, and fluid properties impact. Gas pressure regulation will precede powder tests for different sizes, optimizing cleaning procedures, and evaluating ultrasound solutions. Planning includes filter installation, test execution, and plant shutdown for remaining installations.

  1. DSF test bench update A. Francescon ITS cooling meeting 13.09.11

  2. First tests60 μm filter characterization and thermosiphon results comparison Dp [bar] Comparison between New results and thermosiphon For 60 um filter @ 0 W Flow [g/s]

  3. Error range evaluation Dp [bar] Example: +/- 20% error Flow [g/s]

  4. Next tests schedule • Dp variation on 60 μm filters (error range evaluation) (expected required time: 1 day); • Differences in capillaries pressure drop (exp. req. time: 2 days) • Effect of the fluid thermodynamical properties on the pressure drop over the capillaries and the sector (thermal bath) (exp. Req. time: 2 days); N.B. For this test we need to regulate the gas pressure; After that we could start with powder tests (the two filters are therefore required).

  5. Powder tests • Dp evaluation for different powder sizes • Cleaning procedure optimization • Test of ultrasound solutions (Rosario)

  6. Possible planning • Installation of the filters (while the line is empty); • Carrying out of tests; • Plant stop to carry out remaining installations on the plant (dummy load, flow meter…).
