<P>PROBLEM TO BE SOLVED: To provide a plate type heat exchanger having a small pressure loss and a high heat transmission efficiency by suppressing occurrence of exfoliation and deviation of fluid and a stagged area. <P>SOLUTION: This plate type heat exchanger 1 is provided with a plurality of heat transmission plates 2 stacked with one another and having clearances 4 between layers, and partition walls 3 interposed between the clearances 4, having inlets 51 and outlets 52 opened in the edge parts of the heat transmission plates 2, and partitioning and forming interlayer passages extending in the surface direction of the heat transmission plates 2. Fluid having different temperatures alternately flows in the clearances 4 adjoined in the stacking direction in the both sides of the heat transmission plates 2 so as to exchange heat via the heat transmission plates 2. At least, one of the interlayer passages is a flow control passage 5 having a flow control means 6 controlling the flow of the fluid flowing therein from the inlet 51 and flowing thereout from the outlet 52. <P>COPYRIGHT: (C)2003,JPO |
