Trompil hurricane band and be equipped with its heat exchange tube

The utility model provides a trompil hurricane band in the heat exchange tube, through the hurricane band from the heat exchange tube wall far away, set up the trompil apart from heat exchange tube central line nearer position, both can reduce the hurricane band always to meet the stream interface long -pending, reduce the flow resistance, the whirl that can make the hurricane band produce again becomes complicated, additional reinforcing main flow region fluid and near -wall region fluidic are mixed to the extra strengthening heat exchang effectively improves enhanced heat transfer's comprehensive properties, improves the PEC value promptly.
