Claims

[Scope of utility model registration request]

It has a core in which many core plates are laminated,
The core includes a first heat exchange chamber in which a first fluid circulates;
A second heat exchange chamber adjacent to the first heat exchange chamber in which a second fluid circulates and heat exchange is performed with the first fluid, and a second heat exchange chamber inserted between the upper and lower core plates to introduce the first fluid. A direct pipe that connects the port and the filter device to form a supply passage for the first fluid, and a direct pipe that is provided in a part of the first heat exchange chamber so that the first fluid returning from the filter device goes directly to the discharge port. A housing-less type heat exchanger comprising a guide plate that regulates the flow rate and changes the flow direction.
