The first and second fluids are supplied to and heat exchange is performed. When a phase change occurs due to heat exchange, the flow is smoothed by supplying the fluid to the internal space R2 of the wider shell 1. The first fluid flows through the flow path in the heat exchange element 2 as shown by the arrow A in FIG. 1, and the second fluid is between the heat exchange elements 2 or as shown by the arrow B. It flows through the flow path formed between 2 and the shell 1.

で、熱交換効率が一層高められている。The wave pattern is formed on the plate 4 for partitioning the flow path as described above, and since it is inclined at a predetermined angle α with respect to the main direction of the flow connecting the openings 7, the flow path is vertically and horizontally. It is a complicated one that bends to
Therefore, the flow near the surface of the plate 4 becomes a turbulent flow, and the heat exchange between the flow and the plate 4 is efficiently performed. In this embodiment, the plate surface is made rough and the wettability of the phase changing fluid on the surface of the plate 4 is enhanced, so that the heat exchange efficiency is further enhanced.

強度的にも大変好ましい。Further, by forming the unevenness on the plate 4 into a wavy pattern and intersecting the wavy pattern at a predetermined angle, the intersections of the grid-like ridge lines become the contact portions 5 and 10 and are evenly arranged on the plate 4 surface. Therefore, the strength of the heat exchange structure 3 is also very preferable.

A sine wave close to that of (a) is advantageous in terms of heat transfer property, strength, etc., but it is more complicated as shown in FIG. 2 (b) depending on the viscosity and phase change characteristics of the heat exchange fluid used. Any other shape may be used, or another shape can be appropriately selected. Further, although the upper and lower plates 4 have the same wavy pattern in this embodiment, they may be used in an appropriate combination.

Alternatively, a combination of a wavy pattern and spot-like unevenness may be used.

きる。As described above, according to the present invention, since the flow path bent by the unevenness is formed inside and outside the heat exchange element composed of one or two kinds of parts, the number of parts can be reduced. It is possible to provide a heat exchanger having a low cost and efficient heat exchange function by a simple manufacturing process. Further, by fixing the contact portions of the unevenness, the strength can be further improved, and the unevenness is periodically formed so that heat exchange can be performed uniformly, the heat exchange function is high, and there is no thermal deformation. A heat exchanger with high durability can be provided.

It is possible to provide a heat exchanger that has a complicated flow path that bends two-dimensionally with a relatively simple structure and that has a low cost and an efficient heat exchange function. Further, if the peripheral portions of the plates are bent to form contact surfaces parallel to each other between adjacent plates, and the contact portions or the contact surfaces are fixed by welding or brazing, a relatively simple and low-cost work process. Thus, a strong and leak-free joining can be performed, and the so-called in-furnace brazing can be used to greatly simplify the working process and reduce the cost.
