The present invention relates to a device for improving heat transfer in a three-dimensional (3D) heat exchanger. More particularly, the present invention relates to a device for improving heat transfer in a 3D heat exchanger by forming a uniform flow field in a fluid flowing into the heat exchanger. According to the present invention, it is characterized by arranging a flow distribution device at an inlet of a pipe through which a fluid flows to form a uniform flow field. The flow distribution device has a plurality of holes formed on a circumferential surface and the end to distribute the fluid not only in the center but also in the periphery. In addition, a flange is formed at one end to be coupled between the pipe and a diffusion part. The distributed fluid passes through the heat exchanger, and, at this time, one or more screens are disposed to form a more uniform flow field of the fluid. 본 발명은 3차원 열교환기 열전달 향상을 위한 장치에 대한 것으로, 더 자세하게는 열교환기로 유입되는 유체가 균일한 유동장을 형성하여 3차원 열교환기 열전달 향상을 위한 장치에 관한 것이다. 유체가 유입되는 배관 입구에 유동분배장치를 배치하여 균일한 유동장을 형성하는 것이 특징으로, 유체 분배장치는 원주면과 단부에 다수의 홀이 형성되어 중앙 뿐 아니라 주변으로 유체를 분배한다. 또한, 일단에 플랜지가 형성되어 배관과 확산부 사이에 결합되어진다. 분배된 유체는 열교환기를 통과하게 되는데 이때, 적어도 하나 이상의 스크린이 배치되어 유체의 유동장을 더 균일하게 형성할 수 있는 특징이 있다.
