RFQ linacs are useful for large scale research facilities such as SNS, ADS and FRIB. RFQ are necessary to use for low-energy nuclear and radioactive ion physics (e.g., DERICA - Dubna Electron - Radioactive Ion Collider fAcility project, Dubna, Russia). Some solutions are applied for RFQ to oper-ate in CW mode. The decrease of accelerating field and of RF field overvoltage is one of that solutions. Maximal field for CW RFQ is traditionally limited by 1.3-1.5 of the Kilpatrick criterion value comparatively of 1.8-2.0 for the pulse mode. But the thermostabilization of the RFQ cavity is very important problem. Accelerating structure undergoes high thermal loads for operating a CW mode, therefore water cooling system is needed. In this report a selection of an optimal resonator shape and water cooling system con-figuration was done and thermodynamics simulation results will presented.
