cold sink meaning in Chinese

冷却散热片
冷却散热器

In this thesis , a closed brayton cycle is proposed , in which the supercritical lng is taken as its cold sink and an industrial waste heat as its heat source . in this thermodynamic system , the heat releasing process in the brayton cycle is a inconstant temperature process and it matches the process of lng boiloff well , therefore , the exergy loss in the heat transfer process is reduced . at the same time , waste - heat can be utilized effectively in the system
一、利用lng冷(火用)与工业余热的闭式brayton循环热力分析本论文讨论了lng在超临界压力下汽化时，选择无相变的brayton循环与之匹配，因为brayton循环的放热过程为变温过程，与lng的汽化过程有可能做到较好的温度匹配，减少换热过程的不可逆损失。
