The invention discloses a refrigeration bag of an aircraft environment control system. The refrigeration bag is mainly composed of a first fuel oil and air radiator, a mixed radiator, an air dynamic pressure bearing turbine cooler, an outer anti-icing heat insulation cover, a hoop, a system pipeline and the like. The first fuel oil and air radiator and the mixed radiator are both of an aluminum alloy plate-fin heat exchanger structure, and the air dynamic pressure bearing turbine cooler is a boosting type turbine cooler. A second fuel oil and air radiator, a heat regenerator, a condenser and a high-pressure water separator are integrated in the mixed radiator, so that the mixed radiator is not dispersedly mounted at each corner of the airplane according to single components any more. According to the invention, the first fuel oil and air radiator, the mixed radiator and the air dynamic pressure bearing turbine cooler are connected in series through system pipelines, hoops and the like, compared with a traditional design scheme, the weight is reduced by at least 20% or above, the manufacturing difficulty is reduced, the later maintainability is improved, and the occupied space is greatly reduced.
本发明公开了一种飞机环控系统制冷包,主要由第一燃油空气散热器、混合散热器、空气动压轴承涡轮冷却器、外防冰隔热罩、卡箍和系统管路等部分组成。第一燃油空气散热器、混合散热器均为铝合金板翅式换热器结构,空气动压轴承涡轮冷却器是一种升压式涡轮冷却器。混合散热器中集成了第二燃油空气散热器、回热器、冷凝器和高压水分离器,从而不再按照单一部件分散安装在飞机的各个角落。本发明中,第一燃油空气散热器、混合散热器和空气动压轴承涡轮冷却器采用系统管路、卡箍等串接起来,相比传统设计方案减重至少20%以上,降低了制造难度,提高了后期可维护性,大幅缩小了空间占用。
