(Embodiment 1)
First, the features of the flow path plate manufacturing apparatus according to the first embodiment of the present disclosure will be described in comparison with other flow path plates.

As an example of the heat exchange element using the flow path plate, there is the heat exchange element 8 shown in FIG. The heat exchange element 8 is formed by stacking a plurality of flow path plates 800 in the vertical direction. Each flow path plate 800 includes a flow path forming plate 801 for forming a flow path and a partition plate 802 for partitioning the flow path. A fluid flows from the back to the front of the paper surface in the flow path separated by the flow path forming plate 801, for example, the flow path 801a, and the fluid flows from the front to the back of the paper surface in the flow path 801b. When fluids having different temperatures flow through the flow path 801a and the flow path 801b, heat is exchanged between the two fluids via the flow path forming plate 801.

Here, if the surface area of the flow path forming plate 801 is large, the area contributing to heat exchange becomes large, and the heat exchange efficiency is improved. Therefore, from the viewpoint of heat exchange efficiency, it is desirable that the number of peaks or valleys per unit volume of the flow path forming plate 801 is large. However, as the number of peaks and valleys increases, the pressure loss in the flow path increases.

If the pressure loss in the flow path is large, the load on the fan that sends the fluid increases. As the load on the fan increases, the durability of the fan also shortens.

From this point of view, as a flow path plate in which the heat exchange efficiency is maintained while suppressing the pressure loss of the flow path, every other mountain portion of the flow path plate shown in FIG. 11 is arranged to reduce the pressure loss.
