    Abstract: A thermosiphon cooling system 100 comprises a reservoir 104 having first portion 110 arranged to store a liquid coolant, a tubing unit 106 coupled to the reservoir and disposed adjacent to at least one superconducting unit 102 to be cooled. The tubing unit is arranged to receive the liquid coolant from the first portion of the reservoir and circulated within the tubing unit to dissipate heat generated by the superconducting unit by varying the density of the liquid coolant at different portions of the tubing unit. A condensing unit 108 comprises a condenser 138 and may be coupled to the reservoir via a first channel 122 and second channel 126. Reservoir may comprise a second portion 112 storing evaporated coolant. A third channel 130 may communicate coolant from the reservoir to the tubing unit. A perforated tube (508, fig 5) may convey gas bubbles out of the tubing unit. A heat exchanger (408, fig 4) may be coupled to the tubing unit to reduce gas bubbles. At least one manifold (304, 306 fig 3) may balance flow through multiple circulation loops. A fourth channel 134 with a release valve 132 may release any built up pressure in the reservoir.
