Sensor modules for the measurement of thermal conductivity of nanofluids using multi-wires in the transient hot wire method

摘要

Sensor modules for the measurement of the thermal conductivity of nano-fluids using multi-wires in a transient hot wire method are provided to allow a small amount of fluid sample by optimizing the length of a sensor. A multi-wire sensor module is manufactured in a cylinder type. The multi-wire sensor module is manufactured in a plate shape. The multi-wire sensor module is constructed more compactly than that of a double wire sensor module. Long wires(3) and short wires(4) are connected to each other through a top connection port(10), a middle connection port(11), and a ground connection port(12). The divided long wires(3) and the short wires(4) are spaced from each other with a predetermined distance of 100 times wire diameter. The lengths of the divided long wires(3) and the short wires(4) are extended to 1000times wire diameter from 300times wire diameter.
