Cooling apparatus and cooling trap including such an apparatus

摘要

The region 1 to be cooled contains the evaporator of a heat pipe 2 which contains a diphase fluid adapted to the desired temperature between about 0 DEG and -100 DEG C. The condenser 7 of the heat pipe is cooled to a set temperature by a copper ring 8 which is cooled by a regulated liquid nitrogen current. Applications in the freeze trapping of solvents contained in a gaseous current.
