Abstract

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.

Description

Technical field [0001] The present invention belongs to the field of civil aircraft application technology, in particular to an aircraft air conditioning system plate-fin type high-efficiency heat exchanger core. Background [0002] The heat exchange principle of the aircraft air conditioning system adopts the engine heat induction and compressed cold air heat exchange method to adjust the cabin temperature, and the heat transfer medium is air, which requires the heat exchanger to have efficient heat transfer and good performance of solid structure. Compared with other structural types of heat exchangers, plate-fin heat exchangers have the characteristics of excellent high efficiency heat transfer, compact and robust structure, and flexible design. [0003] Due to the weight and energy consumption limitations of aircraft parts, most of the aircraft heat exchangers are made of aluminum alloy. Aluminum alloy has high strength ratio, good corrosion resistance, high heat transfer co...
