TOB Cooling tests: Modules and Rods

From testing of single and double modulesto testing of complete rods

• Tests performed in –20 °C. Tmax = 10 °C between silicon and coolant.• Equal cooling in all module positions along the rod.

TOB Cooling tests: System tests

A complete TOB cooling segment with 19 “rods”installed and tested in the tracker cold-room

• Tests in room temperature and –25 °C.• Successful and simple filling and draining.• Equal cooling performance in all parallel rods.
