Abstract：
Designs the spiral oval crosssection tube bundle heat exchanger through changing the structure and route of a conventional heat exchanger. Theoretically analyses the reasons of the efficiency enhancement. The test results show that the total heat transfer coefficient of this type heat exchanger is higher than that of the ordinary one, and the manufacturing cost is lower, the volume is smaller, which indicates a new direction for the development of heat exchangers.
