HEAT CONDUCTION.
GENERAL DESCRIPTION
The unit consists of two parts: a multi section bar for linear heat conduction studies, and a metal disc for radial heat conduction studies.
The unit has 3 sections namely heating, cooling and the center sections. The three sections can be pressed tightly together.
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.
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.
The test unit requires outside water supply for cooling.
