| 冷却剂 | refrigerant A substance that by undergoing a change in phase (liquid to gas, gas to liquid) releases or absorbs a large latent heat in relation to its volume, and thus effects a considerable cooling effect (一种物质，能在改变物理状态(液体到气体，气体到液体)时释放或吸收相对它的体积来说很大的热量，因此起到降温效果。) |
| 冷却塔 | cooling tower A device that aids in heat removal from water used as a coolant in electric power generating plants (一种有助于散热降温的装置。在发电厂里通常用水作为冷却剂。) |
| 冷却水 | cooling water Water used to make something less hot, such as the irradiated elements from a nuclear reactor or the engine of a machine (用于冷却物体(如核能反应器的辐射源或机器引擎)的水。。) |
