thermal conduction |
Also found in: Wikipedia | 0.03 sec. |
thermal conductionTransfer of heat energy resulting from differences in temperature between adjacent bodies or adjacent parts of a body. In the absence of a heat pump, the energy will flow from a region of higher temperature to a region of lower temperature. The transfer of energy occurs as a result of collision among the particles of the matter involved. The rate of transfer of energy is proportional to the cross-sectional area of contact and to the difference in temperature between the two regions. A substance of high thermal conductivity, such as copper, is a good thermal conductor; one with low thermal conductivity, such as wood, is a poor thermal conductor. See also convection, radiation.

Placing thermocouples as close to the surface as possible is a common practice so the surface temperature could be determined later, using the Inverse Heat Conduction Problem (IHCP). The wear-resistant, highly heat-conductive nozzle tips screw directly into the manifold to ensure optimum heat conduction into the gate from a central cartridge heater. 15 Science, simple heat conduction, the diffusion of random molecular vibrations, can't explain how energy propagates through those nanoscale structures. |
