Claims

[Scope of utility model registration request]

A first fluid chamber and a second fluid chamber are formed by a plurality of layered cavities formed by a group of overlapping plate-shaped plates each having a flange on the periphery of the bottom wall.
a first inflow passage and a first outflow passage passing through each second fluid chamber and passing through each first fluid chamber; and a first inflow passage and a first outflow passage passing through each first fluid chamber and communicating with each second fluid chamber. A second inflow passage and a second outflow passage are provided, and some of the plurality of first fluid chambers in the upper portion or the lower portion of the plate group are communicated with each other, and a second fluid chamber between the first fluid chambers is penetrated. A first bypass passage is provided at the upper and lower ends of the plate group, and upper end plates and
The lower end plates are fixed to each other, openings facing the first inflow passage, the first outflow passage, the second inflow passage, and the second outflow passage are provided in one of the upper end plate or the lower end plate, respectively, and an opening is provided in the upper end plate or the lower end plate. 1. A heat exchange core of a heat exchanger having an opening facing a bypass passage.
