Claims

[Claims for Utility Model Registration] Vacant chambers formed in layers by stacking a plurality of dish-shaped plates are alternately used as first heat exchange chambers and second heat exchange chambers, and upper and lower first heat exchange chambers are formed through these chambers. , a second inflow passage, a first outflow passage, and a second outflow passage are provided, the first inflow passage and the first outflow passage communicate with each of the first heat exchange chambers, and the second inflow passage and the second outflow passage communicate with each of the second heat exchange chambers. a second inflow opening in communication with the exchange chamber, an upper end plate fixed to the upper surface of the plate, a hanging portion surrounding the outer periphery of the plate and hanging down at the periphery thereof, and a second inflow opening in the upper end plate communicating with the second inflow passage; A second outflow opening communicating with the second outflow passage is provided, a lower end plate for closing the ends of the second inflow passage and the second outflow passage is provided on the lower surface of the plate; a heat exchange core provided with a first inflow opening and a first outflow opening, each communicating with a first outflow passage;
The upper plate part is provided above the heat exchange core and has a first fluid circulation hole near the center, and the side wall part hangs down from the outer periphery of the hanging part with a gap at the periphery of the upper plate part. A cover formed by attaching the second inflow pipe and the second outflow pipe and joining the lower edge of the side wall to the lower edge of the hanging part of the upper end plate, and a substantially elliptical section between the lower surface of the upper plate and the upper surface of the upper end plate. An oil/water partition that forms a wall and has both ends on its long axis inscribed in the inner surface of the side wall in the vertical direction, dividing the inside of the cover into a first fluid chamber in the center, and second inflow chambers and second outflow chambers on both sides thereof. A stacked heat exchanger comprising: a hanging portion of the upper end plate vertically inscribed in the inner surface of the cover side wall below the portion inscribed in the side wall of the oil/water partition plate.
