PURPOSE:To miniaturize an overall heat exchanger by a method wherein multiple hollow strings are bonded with one another while resin sealing members are provided to seal each end of multiple hollow strings with a shell. CONSTITUTION:Hollow strings 13 made of e.g. polymethylmethallate base polymer etc. as they are bundled are fixed by sealing members 15 made of e.g. epoxy base resin. Helium at high temperature as heat exchanging fluid is supplied from the inlet of covers 11 to be flowed inside the hollow strings 13. On the other hand, cooling fluid supplied from a cooling water inlet 16 is flowed outside the hollow strings 13 depriving them of heat to be drained out of a cooling water outlet 17. Through these procedures, Helium flowing inside the hollow strings 13 is refrigerated due to heat conduction to be discharged out of the outlet of covers 11. |
