    • A system (100) for cooling one or more circulating flows of oil (110), the system comprising: one or more fuel-oil heat exchangers (113), the fuel-oil heat exchangers using fuel for an engine (111) to cool at least one of the one or more circulating flows of oil; and a fuel return line (150) in flow communication with a point downstream of the fuel-oil heat exchangers and a point (151) upstream of the fuel-oil heat exchangers, wherein the fuel return line is arranged so that at least a portion of the fuel exiting the fuel-oil heat exchangers may be diverted to the point upstream of the fuel-oil heat exchangers. Furthermore, a system (100) for cooling a circulating flow of oil (110) may comprise one or more fuel-oil heat exchangers (113) and one or more air-fuel heat exchangers (146', 146"), the fuel-oil heat exchangers using fuel to cool the circulating flow of oil and the air-fuel heat exchangers using air to cool the fuel.
    • 一种用于冷却一个或多个循环流动的油(110)的系统(100),所述系统包括:一个或多个燃料油热交换器(113),所述燃料油热交换器使用用于发动机(111)的燃料来冷却 油的一个或多个循环流中的至少一个; 以及与所述燃料油热交换器的下游侧的点和所述燃料油热交换器的上游的点(151)流动连通的燃料返回管路(150),其中,所述燃料返回管路配置成使得至少一部分 离开燃料油热交换器的燃料可以转移到燃料 - 油热交换器上游的点。 此外,用于冷却油(110)的循环流的系统(100)可以包括一个或多个燃料油热交换器(113)和一个或多个空气燃料热交换器(146',146“), 使用燃料的油热交换器使用空气来冷却油的循环流和空气 - 燃料热交换器来冷却燃料。
