PURPOSE:To simplify the device and also to facilitate maintenance and inspection by connecting each header of one unit or adjacent two units of heat exchangers to a connecting tube header provided with a safety valve. CONSTITUTION:A header 2b arranged on low-temperature gas G2 side of two units of heat exchangers 4 is connected to a connecting tube header 7 arranged at the center through a connecting tube 6. Then, a lower end of the connecting tube header 7 is closed, and a safety valve 8 is provided on upper end. Only one safety valve 8 is thus installed regardless of number of heat pipe groups in screen, therefore a device constitution is simplified and maintenance and inspection are also facilitated. |
