PURPOSE:To improve the heat transfer performance and safety by a structure wherein two different kinds of working fluids flowing within different tubes are heat-exchanged with each other through a sheet heat transfer body folded in zigzags. CONSTITUTION:The heat exchanger 1 consists of a metal tube 5, within which the working fluid A flows, a metal tube 6, within which the working fluid B flows, the metal sheet 7 with the form folded in zigzags and heat insulating material 8. Owing to the structure as mentioned above, the mixing of the working fluids due to the corrosion of the tubes can be prevented and consequently the safety is improved and as well as the heat transfer performance is also improved and at the same time the heat loss can be prevented. |
