中文百科
功率密度功率密度(或体积功率密度或体积比功率)是每单位体积的功率(能量传输的速率)。 对于能量转换器例如电池、燃料电池、摩打等,还有电源供应器或类似机器,功率密度基于其体积。于是又称为体积功率密度,单位是W/m。 当空间有限时,体积功率密度有时是一项重要考虑。 对于往复式内燃机,功率密度——功率每排气量是一个重要的指标。
英语百科
Power density 功率密度Power density (or volume power density or volume specific power) is the amount of power (time rate of energy transfer) per unit volume. In energy transformers including batteries, fuel cells, motors, etc., and also power supply units or similar, power density refers to a volume. It is then also called volume power density, which is expressed as W/m. |
