ねつでんたつ
noun
heat transfer; heat transmission
1. heat transfer; transmission of thermal energy
In physics and engineering, the transfer of thermal energy—especially between a solid surface and a moving fluid, and more broadly the movement of heat from a hotter to a cooler region by conduction, convection, or radiation.
金属(きんぞく)熱伝達(ねつでんたつ)(はや)い。
Metals transfer heat quickly.
熱伝達(ねつでんたつ)効率(こうりつ)()げる設計(せっけい)(もと)められる。
A design that improves the efficiency of heat transfer is called for.
エアコンは空気(くうき)冷媒(れいばい)(あいだ)熱伝達(ねつでんたつ)利用(りよう)している。
Air conditioners make use of heat transfer between the air and the refrigerant.

Formed from (ねつ) (heat) + 伝達(でんたつ) (transmission, conveyance). A core term in thermodynamics and heat engineering.

COMMON COLLOCATIONS:

  • 熱伝達(ねつでんたつ)(りつ): heat transfer coefficient
  • 熱伝達(ねつでんたつ)()い: to have good heat transfer

SIMILAR WORDS:

  • 熱伝導(ねつでんどう): heat conduction — specifically the transfer of heat within or through a solid; 熱伝達(ねつでんたつ) more often refers to exchange between a surface and a fluid.
