Integrated enhanced heat exchange method by combining boundary layer control with mainstream disturbance

摘要

An integrated enhanced heat exchange method by boundary layer control with mainstream disturbance comprises a multiple of heat transfer enhancement units, in which a periodic vortex is formed along a extending direction of the flow control channel by setting boundary layer flow control devices, the vortex cleans the cold and hot side walls, as a result the flow boundary layer that hinders heat transfer is destroyed, and rapidly transferring cold and heat energy generated from the cold and hot side walls to a flow mainstream channel is realized. A mainstream disturbance device is set on the mainstream of flow to form an axial vortex at the back of the mainstream disturbance device, the axial vortex cooperates with a stream from the flow boundary layer to rapidly transfer the cold and heat energy from the flow boundary layer to entire field to form an even temperature field.
