【Q&A Question 166】June 15, 2018: Briefly explain why baffles are installed in the shell side of a heat exchanger In the shell side of a convective heat exchanger, baffles are used to increase the flow velocity and turbulence of the fluid within the shell side, thereby improving the heat transfer efficiency ； At the same time, the baffle also serves to support the heat exchanger tubes. (Unless otherwise specified, all questions and answers are based on hydrogenation units.) ) Correct: 3 wealth, Incorrect: 1 wealth ； Mass posting of posts – rated based on the lowest score ； Replies that are unrelated to the answer are considered spam and will be deleted immediately.

Adding baffle plates is primarily to guide the fluid in the shell side, prevent short circuits, and at the same time increase its velocity as much as possible (within the allowable pressure drop range), in order to achieve better heat transfer and reduce scaling. In horizontal heat exchangers, it also serves to support the tubes and prevent them from sagging or being damaged by vibration.
In the shell side of a convective heat exchanger, baffles are used to increase the flow velocity and turbulence of the fluid within the shell side, thereby improving the heat transfer efficiency； At the same time, the baffle also serves to support the heat exchanger tubes.
The function of the baffle is to prolong the flow time of the fluid in the shell side as much as possible, increasing the heat exchange time and thereby improving the heat exchange efficiency； At the same time, the baffle supports the tube bundle, enhancing its stability.
Baffles are added to increase the flow velocity and turbulence of the fluid in the shell side, thereby raising the heat transfer coefficient and improving heat transfer efficiency; they also serve to support the tube bundle.
Increase the flow velocity and turbulence level of the fluid in the shell side, as well as extend the heat exchange time, in order to improve the heat transfer efficiency； Support for heat exchanger tubes
