Thermosiphon cooling scheme is a productive way of cooling large scale superconducting magnets. The absence of active pumping and the availability of the higher heat capacity parameter “latent heat” make this an attractive cooling method. Nevertheless, the design of such a system demands a well-organized study of the effect of various flow parameters, such as, mass flow rates, flow quality, etc., and also a robust mechanical design of the various components of the system. This paper presents an analytical approach to designing a thermosiphon cooling scheme based on homogeneous flow conditions as well as separated flow conditions. The design of the mechanical components such as the piping is also discussed. The design approach presented here has been applied to the reference design of two large superconducting solenoids, the Production Solenoid and the Detector Solenoid of the Mu2e experiment at Fermilab.
