It becomes extremely large due to the order of magnitude compared to convection heat transfer. For example, the forced convection heat transfer coefficient of air is several tens to several hundreds (Kcal / m 2 h ℃)
In contrast, the boiling heat transfer coefficient of water is several thousand to several tens of thousands (Kcal /
m 2 h ℃). Further, the heat exchange fluid A on the condensation side is introduced from the two fluid inlets 5 to the second heat exchange fluid flow passage through hole 11b. This second heat exchange fluid flow passage through hole 11b is
A passage is formed opposite to the heat exchange fluid flow passage through hole 9a, and the fluid A on the condensation side exchanges heat with the fluid B on the evaporation side through the heat exchange plate 12. After heat exchange, the fluid A on the condensing side merges at the fourth through hole 12b and reaches the second fluid outlet 6 through the first through hole 9b. Further, the first and second heat exchange fluid flow passage through holes 9a, 11b are formed in the first end plate 8, the heat exchange plate 12, and the second
The surfaces of the end plates (10) are strongly polymerized by brazing to form sealed fluid passages.

する。Next, the operation of the plate heat exchanger with seven stacked plates according to the second embodiment of the present invention will be described. The heat exchange fluid A on the condensation side is guided from the heat exchange fluid inlet 3 on the condensation side to the second heat exchange fluid flow passage through hole 11d through the first through holes 9d and 12d. Here, it is divided into four, passes through the respective second through holes 12c and 9c, and reaches the fluid outlet 4 on the condensation side. About half of the heat exchange fluid B on the evaporation side is introduced from the heat exchange fluid B inlet 6 on the evaporation side to the through hole 9a for the first heat exchange fluid flow passage, where the heat exchange fluid provided with the porous layer 16 is provided. It passes through the flow path through hole 9a and reaches the outlet 5 of the heat exchange fluid B on the evaporation side. On the other hand, pass through about half of the heat exchange fluid B in the evaporation side and the fourth through holes 12b, 11b, the 13b, is guided to the third heat exchange fluid passage through hole 14a. Then, it passes through the heat exchange fluid passage through hole 14a provided with the porous layer 16 and passes through the third through holes 13a and 11a.
It passes through a and 12a and reaches the outlet 5 of the heat exchange fluid B on the evaporation side. The second heat exchange fluid flow passage through-hole 11b has a passage formed opposite or orthogonal to the first and third heat exchange fluid flow passage through-holes 9a and 14a. Here, the exchange fluid A exchanges heat with the heat exchange fluid B on the evaporation side from both sides via the heat exchange plates 12 and 13. At this time, boiling heat transfer occurs in the porous layers 16 and 18 provided in the through holes 9a and 14a for the heat exchange fluid passage. Therefore, the heat exchange efficiency is improved.
