The invention relates to a porous material pore performance detection device. The device comprises a power source which is used for driving a detection gas flow to pass through a porous material, thegas inlet end of the porous material being a first detection position, and the gas outlet end of the porous material being a second detection position; the temperature difference between the detectionairflow and the porous material is greater than the minimum difference value of thermal imaging; the device further comprises a sensor group which comprises a pressure sensor and a thermal imaging sensor and is used for acquiring a pressure value of the first detection position, a pressure value of the second detection position and heat distribution data of the surface of the porous material andsending the detection data to a terminal for calculation and processing. According to the device, a medium in the prior art is replaced by the detection airflow, the cost is remarkably reduced compared with the prior art, no da
