PURPOSE:To permit to use the same kind of operating fluid for one set of heat exchanger and prevent the heat pipe from being broken by the increase of internal pressure by a method wherein the heat pipes, penetrating through a bulkhead, are arranged for both heat exchangers through fluidized beds. CONSTITUTION:High-temperature fluid flows into the fluidized bed heat exchanger 2 through an inlet port 7, is distributed uniformly by a dispersing plate 6, ascends after heating the heat pipes 5... through the fluidized bed 4 and flows out of an outlet port 8. Low-temperature fluid flows into the heat exchanger 3 through the inlet port 9 and flows out of the outlet port 10 after being heated by the heat pipes 5.... In case a temperature change from the inlet port to the outlet port of the fluid is large, the fluid, whose temperature change is large, is flowed through the fluidized bed heat exchanger 2 and heat pipes 5.... The change of temperature at the inlet port of the fluid of the side of fluidized bed heat exchanger 2 is eliminated substantially as shown by broken lines B', A' and the temperature change from the inlet port to the outlet port is reduced in both fluids A, B. In case the temperature change of both fluids A, B is large, both heat exchangers 2, 3 are used as fluidized bed heat exchanging sections. |
