摘要： The present invention concerns a measuring device for measuring dynamic thermal conductivity according to shear rate at a temperature in a normal state, with even a small quantity of a micro-structured fluid, and for accurately measuring dynamic thermal conductivity by preventing convection based on concentration and temperature gradients to minimize heat loss. The device of the present invention comprises: upper and lower fixing plates vertically separated from each other, a lower body defining a side surface of a space between the upper and lower fixing plates, a rotation plate disposed at the space to form a gap with the upper fixing plate and the lower fixing plate, a shaft penetrating the upper fixing plate to be coupled with the rotation plate, a heater installed at an upper portion of the upper fixing plate, and a thermocouple installed on the upper and lower fixing plates. When the rotation plate rotates, the micro-structured fluid filled in the space between the upper and lower fixing plates enters a dynamic state, and simultaneously, the dynamic thermal conductivity of the micro-structured fluid filled in the space is measured with the heater being put into operation and a fixed heat flow being supplied.
