Claims (1)

[Scope of utility model registration request] It has a housing and an annular core housed in the housing, and the core is formed by laminating a large number of plates and is connected to at least two types of heat exchange chambers formed between each plate and to each other along the thickness direction. It has a first inflow chamber and a first outflow chamber formed in parallel, and the first inflow chamber and the first outflow chamber are in communication with each other through one heat exchange chamber, and between the core and the housing. An inlet outer chamber and an outlet outer chamber are formed which are separated from each other, and the inlet outer chamber and the outlet outer chamber are provided in the core in parallel with the first inlet chamber and the first outlet chamber, and are connected to the other heat exchange chamber. A heat exchanger, characterized in that it is connected to a second inlet chamber and a second outlet chamber, which are communicated with each other via.
