Embodiment Construction

[0033] The following is attached Figure 1-4 The application is described in further detail.

[0034] The embodiment of the present application discloses a heat exchanger with functions of ozone conversion and high-temperature pre-cooling. refer to figure 1 , the heat exchanger includes a plurality of partitions 1 arranged at intervals and a seal 2 fixed between two adjacent partitions 1, and two adjacent partitions 1 and the seal 2 between two partitions 1 are in common Enclosing the installation chamber 3. Wherein, the installation cavity 3 includes a plurality of hot cavities 31 for the air introduced by the aircraft engine to enter and a plurality of cold cavities 32 for the fan pipeline air of the gas turbine engine to enter, and the hot cavities 31 and the cold cavities 32 alternately It is set so that the cold gas in the cold cavity 32 can exchange heat with the hot gas in the hot cavity 31, so as to realize the cooling and precooling of the high-temperature gas.

Abstract

The invention relates to the field of heat exchangers, in particular to a heat exchanger with ozone conversion and high-temperature precooling functions. The heat exchanger comprises a plurality of partition plates and sealing strips fixedly connected between every two adjacent partition plates; every two adjacent partition plates and the sealing strips located between every two partition plates jointly define a mounting containing cavity; each mounting containing cavity comprises a hot cavity body and a cold cavity body, gas introduced by an aircraft engine enters the hot cavity body, air of a fan pipeline of a gas turbine engine enters the cold cavity body, hot cavity fins for guiding the gas flowing direction are mounted in the hot cavity body, and the surfaces of the hot cavity fins are coated with ozone catalysts. The heat exchanger has the advantages that ozone conversion and high-temperature pre-cooling are achieved, meanwhile, the size and weight of the heat exchanger can be reduced, and the energy consumption of an aircraft is reduced.

Description

technical field [0001] The application relates to the field of heat exchangers, in particular to a heat exchanger with functions of ozone conversion and high-temperature precooling. Background technique [0002] In the environmental control system of modern civilian fixed-wing transport aircraft, an ozone converter and a high-temperature precooler are installed at the same time. [0003] Since the cruising altitude of fixed-wing transport aircraft is generally above 10km, the ozone concentration in the air is much higher than the ground ozone concentration, exceeding the concentration range suitable for the human body. The air source in the cabin and cockpit comes from the hot bleed air of the engine, and the ozone converter is to convert and decompose the ozone in the hot bleed air of the engine entering the cabin and cockpit into oxygen, thereby reducing the ozone concentration to a concentration suitable for the human body ;The precooler is to cool down the high-temperat...
