Structure design and strength analysis of disturbing flow and heat transfer enhancing device for heat exchangers

Develops a kind of disturbing flow and heat transfer enhancing device based on a twisted tape. Analyses the strength of two key parts—the cross piece fixed bracket and the twisted tape, and obtains the stress and displacement distribution, the result indicates that the two key parts have enough strength and rigidness, and can ensure that the device works stably and reliably. Actual application shows that the heat transfer enhancing device can effectively improve heat transfer performance and increase the COP of the main unit.
