Abstract
The utility model provides a kind of thermal conductivity detection device, it is related to thermal conductivity detection technical field.The thermal conductivity detection device is used to detect workpiece, the workpiece includes first surface and second surface in predetermined direction each other, the thermal conductivity detection device includes cold plate assembly, hot plate assembly and two heat flow meters, the hot plate assembly includes hot plate and first coating, the hot plate is covered by first coating, one the heat flow meter is arranged between the hot plate assembly and the first surface, another the heat flow meter is arranged between the cold plate assembly and the second surface.Due to the hot plate being covered by first coating, this can reduce the heat that hot plate passes through the mode of radiation heat transfer to workpiece transmission, and then reduce the influence of the heat radiation of hot plate on the accuracy of heat insulation coefficient detection, to improve the accuracy of heat insulation coefficient detection.
