Thermosyphon are heat transport devices that can transfer heat using gravitation. They can work without any external power supply, and have simple structures. Recently, a device which transfers heat from the hot reservoir on the top to the cold reservoir in the bottom was made and investigated the performance by Ippohshi and et.al. In this paper the same type of device and another type of device which was simpler in the structure were made and their performances were compared with each other. It was found that the one made later did not take time before the water in the tube circulated. The apparatus could transport heat up to 290W for the water at temperature of 25℃ in the cooler. The effective thermal conductivity of the tube was in the range between 10^4 and 2×10^5W/(m・K).
