Heat exchanger is one of the most important devices in thermal system. An experimental system is developed for testing the heat-exchange performance of cryogenic compact exchangers. This system mainly consists of a regenerator, a cold box, a liquid nitrogen dewar, two cryogenic transfer lines and other devices. The features of the main components are described in this paper. A measurement system based on PC is developed for this system. All of these make this system more reliable, convenient, and energy-saving.
