WIPO Patent Application WO/2011/158411

A1

Disclosed is a re-condensation device that allows an NMR analysis device to be reduced in overall size and also minimizes heat penetration into a liquid helium tank. Also disclosed is an NMR analysis device provided with said re-condensation device. The disclosed re-condensation device is provided with: a second cooling member (15), part of which is inserted into a neck tube (24), and which re-condenses liquid helium; and a first cooling member (14), part of which is inserted into the neck tube (24). The second cooling member (15) is thermally connected to a second cooling stage (11b) of a chiller (11), and the first cooling member (14) is thermally connected to a first cooling stage (11a) of said chiller (11). The first cooling member (14) has: a first insertion part (20d), which has a diameter that allows insertion into the aforementioned neck tube (24); and an inside contact part (21) that is provided on the outer surface of the first insertion part (20d) and cools heat seals (8 and 9) by contacting, from the inside, a part of the neck tube (24) that outside contact parts (8a and 9a) contact.
