The present invention relates to a plate attached heat exchanger. The plate attached heat exchanger reduces manufacturing time and the number of manufacturing processes to improve productivity and a quality of a product. According to the present invention, a plate (50) having an upper plate (60) and a lower plate (70) is stacked in the heat exchanger, and a flow passage is formed inside the heat exchanger by brazing bonding blade units (61, 71) of the upper plate (60) and the lower plate (70). The wing unit (61) of the upper plate (60) is bent downward, and a material application space (H) is formed between a support surface (73) and the upper wing unit (61) in order to form the heat exchanger. |
