TH 310 HEAT CONDUCTION, Computer Interface



The unit consists of two parts: a multi section bar for linear heat conduction studies, and a metal disc for radial heat conduction studies.

. Linear Heat Conduction Unit.

The unit has 3 sections which can be pressed tightly together. The first section is for heat input where a heater and three temperature sensors at 10 mm interval are installed. The center section has three temperature sensors at 10 mm interval. The last section is a heat sink section where cooling water and two temperature sensors at 20 mm interval are installed.

The center section may be removed and replaced with a smaller heat conduction section or a different heat conduction material. Both replaced sections are without temperature sensors. Matching surfaces of the heat conduction section are accurately finished to minimize conduction resistance and a heat conducting compound may be applied to further reduce resistance. Thermal conductivity of an insulation material can be determined by inserting a thin insulating disc between two heat conduction surfaces.

. Radial Heat Conduction Unit.

The unit consists of a brass disc heated at the center by a heater with cooling water circulating around the periphery. Six temperature sensors are placed along a radius.

    The metallic parts of both linear and radial heat conduction units are effectively insulated inside plastic casings.

. A service module provides power supply, heater control unit, and measuring instruments.

The test unit requires outside water supply for cooling.
