The invention relates to a passive helicopter cabin heating system utilizing lubricating oil waste heat, and belongs to the field of airborne environment control systems. The heating system comprises a lubricating oil system, a passive heat transportation device and a heat exchanger, according to the lubricating oil system, a lubricating oil heat release device is additionally arranged in a traditional lubricating oil system pipeline; the passive heat transportation device at least comprises a shut-off valve, an exhaust/liquid filling pipe, an evaporator, a steam pipeline, a temperature control valve, a cabin radiator, a radiator, a liquid pipeline, a surge tank and a working medium. The evaporator and the lubricating oil heat releaser are arranged in the same heat exchanger to realize heat exchange; a certain amount of working medium is injected into the passive heat transportation device, and finally the shut-off valve is closed; reutilization of waste heat of the lubricating oil is achieved through circulation of a working medium in the passive heat transportation device. The problem that engine performance is affected by cabin heating is solved, and the system has the advantages of being low in compensation and high in energy efficiency and meanwhile has good maintainability.

    本发明涉及一种利用滑油余热的被动式直升机座舱加温系统,属于机载环控系统领域。提出的加温系统包含滑油系统、被动式热运输装置和换热器;所述滑油系统在传统的滑油系统管路中增加滑油释热器;所述被动式热运输装置至少包括关断阀、排气/充液管、蒸发器、蒸汽管路、温控活门、座舱散热器、散热器、液体管路、稳压罐、工质;所述蒸发器与滑油释热器设置于同一换热器中实现热交换;向被动式热运输装置中注入一定量的工质,最后关上关断阀;通过工质在被动式热运输装置内循环以实现滑油余热的再利用。本发明解决了座舱加温对发动机性能影响的问题,具有低代偿、高能效的特点,同时还具有较好的维护性。
