1.
heat conduction; thermal conduction
The transfer of heat through a material by direct contact between molecules, without bulk movement of the material itself. One of the three main modes of heat transfer, alongside convection and radiation.
金属は導熱性が高い。
Metals have high thermal conductivity.
導熱率の低い素材は断熱材に適している。
Materials with low thermal conductivity are suitable for insulation.
建物の壁を通じた導熱を抑えることが、省エネルギー住宅の設計で重要なポイントとなる。
Reducing heat conduction through building walls is an important point in the design of energy-efficient houses.
A compound of 導 (conduct/guide) and 熱 (heat). Describes the physical process by which heat moves through a material from a region of higher temperature to one of lower temperature.
COMMON COLLOCATIONS:
- 導熱性: thermal conductivity
- 導熱率: thermal conductivity coefficient
- 導熱材: heat-conducting material
SIMILAR WORDS:
- 熱伝導: heat conduction (more common term, same meaning)
- 伝熱: heat transfer (broader term including conduction, convection, and radiation)
- 対流: convection (heat transfer through fluid movement)
- 放射: radiation (heat transfer through electromagnetic waves)
