PURPOSE:To obtain a heat insulation device which requires neither a power source nor a steam source for heat insulation by bringing one end of a heat pipe into contact with a base body and the other end into contact with a detection part and a connection part. CONSTITUTION:A heat reception part 7 at one end of the heat pipe 6 is brought into contact with a heat reception part 7 and the other end is wound around a liquid level detection part 2 and the connection part where the detection part 2 is connected to the base body 1; and part of the base body 1 that the pipe 6 contacts, the connection part 3, and detection part 2 are wound with a heat insulator 4 and further covered with a heat insulation cover 5. Consequently, the heat of the base body 1 is absorbed by the heat reception part 7 of the pipe 6 and radiated by the connection part 3 and detection part 2, so they are held at nearly the same temperature with the base material 1. Therefore, neither the power source nor the steam source is required for heat insulation and the need to consume electricity and steam is eliminated. |
