PURPOSE:To facilitate the assembling of a tank and a pipe while enabling accurate sealing of a plurality of partition walls between the outer circumference of the pipe and the tank. CONSTITUTION:A pipe with a diameter less by set dimensions than openings 10 of the plurality of partition walls 8 is used as such 9 to be inserted into an inlet tank 7 as piercing the opening 10 of the partition walls 8 thereby facilitating the insertion of the pipe 9 into the inlet tank 7. Material of the pipe 9, an opening diameter of a supply hole 13 and the like are designed with the set dimensions taken into consideration. Thus, the pipe is expanded elastically outward in a diametrical direction according to a difference of internal and external pressures when the supply hole 13 of the pipe 9 serves as refrigerant thereby eliminating gap between the partition walls 8 and the outer circumference of the pipe 9. |
