Abstract: A thermosiphon for a refrigerating machine which can maintain smooth circulation of working fluid by ensuring the flow of the working fluid into a condenser even if it is condensed in a connecting end of a gas pipe connected to the condenser. The gas pipe 16 connected to the condenser 12 has a connecting end which is formed with a riser pipe 28, thereby constructing a reverse-flow suppressing portion 30 which is brought to a higher position than the condenser 12. Thus, even if the working fluid is condensed in the riser pipe 28, the condensed working fluid can be forcedly allowed to flow down into the condenser 12 by gravitational force.
