Embodiment Construction

[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0028] see figure 1 As shown, the present invention provides a novel wing anti-icing system utilizing airborne waste heat, the system includes four parts, namely skin heat exchanger 1, rotary compressor 2, evaporator 3 and electronic expansion valve 4 ;

[0029] The skin heat exchanger 1 and the rotary compressor 2 are communicated through a second pipeline 5B; high-temperature hot steam flows in the second pipeline 5B; the temperature is not lower than 100°C;

[0030] A third pipe 5C is used to communicate between the skin heat exchanger 1 and the electronic expansion valve 4; the third pipe 5C flows a cooled saturated liquid; the temperature is not higher than 20°C;

[0031] The evaporator 3 communicates with the rotary compressor 2 through a first pipeline 5A; what flows in the first pipeline 5A is dry saturated steam;

[0032] The evaporator 3 communic...

Abstract

The invention discloses a novel wing icing prevention system using airborne waste heat. According to the system, the connection among a skin heat exchanger, a rotary compressor, an evaporator and an electronic expansion valve is realized through a pipeline; a liquid storage device is additionally arranged in an anti-icing cavity of each wing, and a double-skin structure is changed. According to the system disclosed by the invention, an evaporative-cycle anti-icing manner is adopted to an unmanned aerial vehicle, heat source heat of airborne electronic equipment is sufficiently absorbed by using the evaporator and the heat exchanger, is transferred to skin in a flute-shaped tube impact jet flow manner and is subjected to heat exchange with outside supercooling wet air, and the temperature of the skin is increased to the minimum anti-icing temperature, so as to reach the anti-icing effect.

Description

technical field [0001] The present invention relates to an anti-icing system of an aircraft, more particularly, refers to a novel wing anti-icing system utilizing airborne waste heat. Background technique [0002] Modern aircraft, especially unmanned aircraft, use a large number of various electronic components and electronic equipment, resulting in high local heat generation. If effective heat dissipation is not carried out, the performance of electronic equipment will be seriously reduced, and heat dissipation treatment must be carried out. When an aircraft passes through clouds containing supercooled water droplets, many components may freeze, such as wings, leading edges of the empennage, propellers, helicopter rotor blades, engine air intakes, pitot tubes, windshields, etc. The large-scale UAV is the current development trend. The flying height, speed and flight time of large-scale UAVs have been greatly improved, thus entering the icing envelope to generate icing. Co...
