摘要： The present invention relates to a plate heat exchanger for increasing heat exchange efficiency via improvement in the flowability of fluid, promotion of turbulence and the like. The plate heat exchanger according to the present invention includes a plurality of heat exchange tubes stacked in the vertical direction. Each of the heat exchange tubes is formed with upper and lower plates coupled with each other and has an internal fluid channel through which internal fluid passes. Outer fluid channels are formed between the plurality of heat exchange tubes for passing outer fluid. The upper plate is formed with a wave-shaped pattern comprising a plurality of protuberances and a plurality of indentations on the top surface thereof. The lower plate is formed with a wave-shaped pattern comprising a plurality of protuberances and a plurality of indentations on the bottom surface thereof. Each of the heat exchange tubes has an inlet path and an outlet path separated from each other on both sides. The upper plate has upper flanges protruded from the upper portions of the inlet path and the outlet path, and the lower plate has lower flanges protruded from the lower portions of the inlet path and the outlet path. The upper flanges and the lower flanges are connected by insertion to each other, and first and second flat portions are respectively formed in the peripheral areas of the upper flanges of the upper plate and in the peripheral areas of the lower flanges of the lower plate.
