PURPOSE:To improve heat exchanging efficiency and realize the miniaturization of the titled equipment by a method wherein an A1-fin incorporating type heat exchanger is provided with the introducing part and the discharging part of vaporized low pressure gas and a heater while these units are held in dry gas atmosphere. CONSTITUTION:An area in a main body 2, in which an A1-fin 3 is incorporated, is made an air-tight space and the main body 2 is provided with the introducing part 4 and the discharging part 5 of low temperature gas in parallel. A heater 6 is provided between fixed plates 13 so as to pinch a heat exchanger 1. The heat transmission coefficient of the low temperature gas, supplied into the heat exchanger 1 through an introducing port 4a, can be increased remarkably compared with a heating equipment having a conventional flat surface by the increase of contacting areas and turbulent flow generating effect due to the effect of the A1-fin. Further, a low temperature gas heating equipment can be held in dry gas atmosphere by accommodating it in a sealed vessel 15, therefore, the frosting of the heating equipment or the like may be prevented.
