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.
金属は熱伝達が速い。
Metals transfer heat quickly.
熱伝達の効率を上げる設計が求められる。
A design that improves the efficiency of heat transfer is called for.
エアコンは空気と冷媒の間の熱伝達を利用している。
Air conditioners make use of heat transfer between the air and the refrigerant.
Formed from 熱 (heat) + 伝達 (transmission, conveyance). A core term in thermodynamics and heat engineering.
COMMON COLLOCATIONS:
- 熱伝達率: heat transfer coefficient
- 熱伝達が良い: to have good heat transfer
SIMILAR WORDS:
- 熱伝導: heat conduction — specifically the transfer of heat within or through a solid; 熱伝達 more often refers to exchange between a surface and a fluid.
