3d heat exchanger heat transfer enchancement device

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.

         8 . The heat exchanger heat transfer enhancement device of  claim 7 , wherein the holes of the screen increase in size from a central portion to a peripheral portion. 
     
     
         9 . The heat exchanger heat transfer enhancement device of  claim 7 , wherein the screen disposed on a front surface of the heat exchanger is formed to be convex in an inflow direction of the screen. 
     
     
         10 . The heat exchanger heat transfer enhancement device of  claim 7 , further comprising a partition disposed on an inner surface of the diffusion portion and disposed to be parallel to a flow direction of the fluid. 
     
     
         11 . The heat exchanger heat transfer enhancement device of  claim 10 , wherein an internal space of the diffusion portion is uniformly separated along a circumference of the flow distribution device by partitions. 
     
     
         12 . The heat exchanger heat transfer enhancement device of  claim 10 , wherein the partitions are spaced apart from the flow distribution device in a circumferential direction. 
     
     
         13 . A method for enhancing heat exchanger heat transfer using the heat exchanger heat transfer enhancement device of  claim 1 , the method comprising:
 an inflow operation in which a fluid is introduced from a pipe;   a first distribution operation in which the introduced fluid is distributed by the plurality of holes of the flow distribution device;   an entering operation in which the distributed fluid moves to a heat exchanger by a diffusion portion and a flow of a gas enters uniformly the entire front surface of the heat exchanger; and   a cooling operation in which the fluid passing through the heat exchanger is cooled.   
     
     
         14 . The method of  claim 13 , further comprising:
