提出了耦合热机阵列作为研究线性不可逆热力学中个体行为和集体行为之间权衡的典范模型。分析揭示了控制参数的存在，该参数选择了整个阵列的不同运行状态。特别是，考虑了最大效率和最大功率的情况，给出了后者的Curzon-Ahlborn效率的一般推导，令人惊讶的是，它并不依赖于阵列中的单个发动机是否工作在最大功率下。
Arrays of coupled heat engines are proposed as a paradigmatic model to study the trade-off between individual and collective behavior in linear irreversible thermodynamics. The analysis reveals the existence of a control parameter which selects different operation regimes of the whole array. In particular, the regimes of maximum efficiency and maximum power are considered, giving for the latter a general derivation of the Curzon-Ahlborn efficiency which surprisingly does not depend on whether or not the individual engines in the array work at maximum power.
