In the conventional plate heat exchanger described above, the upper and lower guide bars (3a) and (3b) are integrally formed. Therefore, when adding a large number of heat transfer plates (5) (5) ... to modify them, the guide bars (3a) (3b) having the existing dimension and length are removed and the guides having the new dimension and length are removed. Bar (3a) (3b)
Must be replaced. In this case, the heat transfer plates (5) (5) are all removed from the upper and lower guide bars (3a) (3b), and the guide bars (3a) (3b), the fixed frame (1) and the support (2) are also disassembled. Therefore, there is a problem that a huge amount of replacement (remodeling) time is required and a large amount of production line stoppage is brought about.

Further, the above-mentioned conventional plate heat exchanger is
When suspending a large number of heat transfer plates (5) (5) ..., the guide bars (3a) (3b) also need to be of a long size, which increases the overall length and may exceed the limit length for land transportation. There is. Therefore, in order to transport the plate heat exchanger in the assembled state by land, the number of heat transfer plates (5) (5) per plate heat exchanger is limited so that the length of the land transport does not exceed the limit. There must be. In this case, there is a problem that the number of plate heat exchangers increases due to the limitation of the number of heat transfer plates (5) (5) ...
