The figure is a side sectional view equivalent to FIG. 2 showing another embodiment of this invention, and FIG. 4 is a front view showing a conventional heat exchanger.
FIG. 5 is a side cross-sectional view of that of FIG. 4. In the figure, A is the primary fluid, A ₁ and A ₂ are branch channels,
1a, 1b, and 1c are heat exchanger plates, 2 is a through hole, 4 is an enlarged flow path, 5 is a narrow flow path, 6 is a distribution pipe, 7 is a downstream guide groove, and B is a secondary fluid. In other figures, the same reference numerals indicate the same or corresponding parts.

Claims

[Claims for Utility Model Registration] (1) The branch channels are installed opposite to each other so that the cross-sectional areas of the branch channels differ periodically along the flow direction of the primary fluid flowing between them, and Consisting of a plurality of heat exchanger plates having a large number of through holes, and a distribution pipe for a secondary fluid that passes through each of these heat exchanger plates in a laminated state and exchanges heat with the above-mentioned primary fluid, and is connected to each branch flow path of the above-mentioned primary fluid. A pressure difference between an enlarged flow path and a narrow flow path formed back to back generates a heat transfer fluid passing through the through holes between them, and each heat transfer plate has a heat transfer fluid formed on its surface. A heat exchanger characterized by having a concave guide groove for flowing dew water. (2) The scope of the utility model registration claim, in which secondary fluid distribution pipes are located in the middle of dew water flow guide grooves recessed in the surface of each heat transfer plate, penetrating these in a stacked state. The heat exchanger according to item 1.
