System And Method Of Soakback Mitigation Through Passive Cooling

A gas turbine engine cooling system comprises a gas turbine engine 100, and the gas turbine engine 100 includes a core engine 102, a cold sink, a core undercowl space 131, and a core cowl 130 at least partially surrounding the core engine and defining a radially outer wall of the core undercowl space. The gas turbine engine cooling system comprises: an undercowl component 402 positioned in the core undercowl space; and a heat pipe 414 comprising a first end 416, a second end 418, and a conduit 420 extending therebetween, said second end is thermally coupled to the cold sink, said first end thermally is coupled to said undercowl component, wherein said heat pipe facilitates transfer of a quantity of heat from said undercowl component to the cold sink. 种燃气涡轮发动机冷却系统(400，500，600)包括燃气涡轮发动机(100)。燃气涡轮发动机包括核心发动机(102)、冷却散热器(602，202，316，302，702)、核心罩下空间(131)和核心罩(130)，核心罩(130)至少部分地包围核心发动机且限定核心罩下空间的径向外壁。燃气涡轮发动机冷却系统包括定位在核心罩下空间中的罩下构件(402)。燃气涡轮发动机冷却系统还包括包含第端(416)、第二端(418)和在它们之间延伸的管道(420)的热管(414)。第端热联接至罩下构件，且第二端热联接至冷却散热器。热管有助
