The invention belongs to the technical field of civil aircraft application, and particularly relates to a plate-fin type efficient heat exchanger core of an aircraft air conditioning system. Comprising a core body, the core body comprises a structure frame formed by stacking a plurality of units and end plates on the two sides of the core body, cold path fins or hot path fins are arranged in the structure frame, a cold path channel is formed between the structure frame and the cold path fins, a hot path channel is formed between the structure frame and the hot path fins, and the cold path channel and the hot path channel are communicated with each other. The cold path channels and the hot path channels are arranged in a staggered and stacked mode, the structural frame is arranged in a hexagonal shape, and the structural frame comprises a middle heat dissipation area with the middle arranged in a rectangular shape and side flow guide areas arranged on the two sides in a triangular shape. According to the heat exchanger, the heat exchange air flow can stay in the core body for a longer time, and meanwhile, the air flow is distributed more uniformly by utilizing the change of the shape, so that the purpose of improving the heat exchange effect is achieved.

    本发明属于民用飞机应用技术领域,尤其涉及一种飞机空调系统板翅式高效热交换器芯体。包括芯体本体,所述芯体本体包括若干个单元相互堆叠的结构框架以及在芯体本体两侧端板,所述结构框架内设置有冷路翅片或热路翅片,所述结构框架和冷路翅片之间构成冷路通道,所述结构框架和热路翅片之间构成热路通道,所述冷路通道和热路通道之间交错堆叠设置,所述结构框架呈六边形设置,所述结构框架包括中部呈长方形状设置的中部散热区以及设置在两侧呈三角状设置的侧部导流区,本发明通过对现有的芯体的形状进行改进,使换热的气流在芯体内停留的时间更长,同时,利用形状的变化,使气流分布的更为均匀,从而达到提高换热效果的目的。
