| Abstract: | With various methods to test,compare and analyze four kinds of shell-tube heat exchanger with small diameter tubes arranged surrounding the edge of tube bundle which is in a structure of single segment baffle,1/3 variable cross section combined with 2/3 bare tube,2/3 variable cross section tube combined with 1/3 bare tube and 1/3 variable cross section tube combined with 2/3 bare tube.The result gives idea that the longitudinal flow shell-tube heat exchanger with the combined tube bundle in variable cross section without baffle plate can provide a certain basis of promoting in industry. |
