Abstract: Provided is a heat exchanger heat transfer enhancement device, and in particular, to a heat exchanger heat transfer enhancement device by allowing a fluid flowing into a heat exchanger to form a uniform flow field. A flow distribution device is disposed at an inlet of a pipe through which a fluid is introduced, and the flow distribution device includes a plurality of holes formed on a circumferential surface and an end portion to distribute the fluid to the center and the periphery. Also, a flange is formed at one end and coupled between the pipe and a diffusion portion. The distributed fluid passes through a heat exchanger, and here, one or more screens are disposed to make a flow field of the fluid more uniform.
