Summary: It is odd segment of a circle to fold to check structure respectively stream board, 1/3 becomes sectional combination of canal and 2/3 light canal, 2/3 becomes sectional canal and 1/3 light are in charge of combination and become sectional in 1/3 on the basis that canal and 2/3 light provide combination, the heat exchanger of type of 4 kinds of envelope that decorates small diameter canal in part of brim of this canal card again undertakes experimenting comparative mixing analytic. Experiment eventuate is not had fold stream board become sectional to provide mixture check heat exchanger of fore-and-aft shell type drifting a canal provided certain basis in the promotion on industry.

Keyword: Check structure; Smooth canal; Become sectional to be in charge of; Conduct heat to be pressed fall

As industrial development, right cold the research that changes equipment carapace Cheng to conduct heat is ceaseless grow in quantity, among them the form that way of aggrandizement of Cheng of a kind of carapace is stay of change carapace Cheng. Without fold stream board mixture check is efficient heat exchanger is be in charge of with light and become sectional Guan Xianglin and support becomes sectional to be in charge of be out of shape raised as the canal of stay, it is replaced fold stream lever and fold stream board wait for the stay between the canal. The article passes what the experiment compares its and tradition then to fold stream board heat exchanger is in the difference of performance side.

1 experiment

Experiment by become 4 times in group below:

(The stay between 1) canal flows to fold board the experiment of housing Cheng function of envelope type heat exchanger.

(2) check structure becomes sectional to be in charge of what provide combination with 2/3 light to not have for 1/3 fold the housing Cheng performance that grades heat exchanger of board canal shell type to experiment.

(3) check structure becomes sectional to be in charge of what provide combination with 1/3 light to not have for 2/3 fold the housing Cheng performance that grades heat exchanger of board canal shell type to experiment.

(It is fore-and-aft that 4) flows as a result of bypass the main abuse that sorts heat exchanger, the article undertook check structure becomes sectional to be in charge of as smooth as 2/3 canal to combine for 1/3, and the housing Cheng function that small diameter canal assigns along the part outside check experiments.
