Abstract：The high flux heat exchange tube is the product based on the intensive study of the heat transfer enhancement technology for the shell and tube heat exchanger tube，whoes strengthening heat transfer principle is interpretated by introducing the active nucleation site and the buble formation. The sintered high flux heat exchanger tube is a representative type of high flux heat exchanger tubes. In the boiling condition with phase change，its heat transfer enhancement effect has been proved, but the level of reinforcement is uncertain. The evaporation pool boiling test results of the sintered high flux heat transfer tube developed by our company and the common smooth tubes are obtained to study the real heat transfer performance. Some suggestions for the high flux exchanger design and the development of high flux tube are given.
