にできる。Effect of the Invention As described above, the present invention provides two primary refrigerant flow passage holes for flowing the primary refrigerant in the thickness direction and two secondary refrigerant flows for flowing the secondary refrigerant in the thickness direction. A seal plate having a passage hole; and a primary side for allowing the primary refrigerant flowing from one of the primary refrigerant passage holes of the seal plate to flow out to the other primary refrigerant passage hole of the seal plate. A primary having a refrigerant flow passage and two secondary refrigerant flow passage holes provided at positions opposed to the secondary refrigerant flow passage holes of the seal plate for flowing the secondary refrigerant in a plate thickness direction, respectively; A side plate and a secondary refrigerant for allowing the secondary refrigerant flowing from one of the secondary refrigerant flow passage holes of the seal plate to flow out to the other secondary refrigerant flow passage hole of the seal plate. Channel and the primary side of the seal plate A secondary plate having two primary-side refrigerant flow holes for flowing the primary-side refrigerant in the thickness direction, which is provided at a position facing the refrigerant flow-path hole, and a pair of end plates, In a laminated heat exchanger in which a plurality of the primary side plates and the secondary side plates are alternately laminated with a seal plate interposed therebetween, and the end plates are arranged at both ends thereof,
At the substantially central portion in the stacking direction of the stacked heat exchanger, two primary sides are provided respectively at positions corresponding to the primary-side coolant passage holes of the seal plate for flowing the primary-side coolant in a plate thickness direction. Refrigerant flow path holes, and two secondary-side refrigerant flow holes for allowing the secondary-side refrigerant to flow in the plate thickness direction, respectively, provided at positions corresponding to the secondary-side refrigerant flow holes of the seal plate, A partition plate having four refrigerant inlet / outlet holes, one end of which is communicated with the primary refrigerant passage hole and the secondary refrigerant passage hole, and the other end is exposed on the same side surface parallel to the plate thickness direction. As a result, both the primary refrigerant and the secondary refrigerant have a shorter distance to the refrigerant flow path at both ends, and the variation in the flow rate of the refrigerant flowing through each refrigerant flow path is reduced, so that the heat transfer area can be effectively used and heat exchange can be performed. Performance is improved. In addition, since the refrigerant inlet / outlet holes for the primary-side refrigerant and the secondary-side refrigerant are provided in the partition plate provided substantially at the center of the stacking type heat exchanger in the stacking direction, the refrigerant inlet / outlet holes for the primary-side refrigerant and the secondary-side refrigerant are provided. When the refrigerant tubes are connected, the dimension of the stacked heat exchanger in the stacking direction does not increase. Also, since all four refrigerant inlet / outlet holes of the primary side refrigerant and the secondary side refrigerant are exposed on the same side surface parallel to the thickness direction of the partition plate, the four refrigerant inlet / outlet holes can be opened from the same direction. The plate can be easily manufactured, and when connecting the refrigerant pipes to the four refrigerant inlet / outlet holes, the work can be performed from the same direction. Therefore, the connection work of the refrigerant pipes is facilitated. Since it is possible to concentrate on the line, the laminated heat exchanger in a state where four refrigerant pipes are connected can be made compact.
