Zusammenfassung:The invention discloses a method for determining thermal-conduction resistance of a metal foam porous medium. The method comprises the following steps: placing a to-be-determined metal foam porous medium between a hot plate and a cold plate and carrying out vacuumization; energizing and heating the hot plate at an upper part and cooling the cold plate at a lower part via a cooling module; when the whole heat transfer process reaches a stable state and a certain degree of vacuum is reached and maintained unchanged in a test section, acquiring data like temperature, current and voltage in real time by using a data acquisition and processing system; and processing the acquired data by using the data acquisition and processing system so as to eventually obtain thermal-conduction resistance of the metal foam porous medium and providing a test report. The determination method provided by the invention is rapid and simple and has high accuracy.
