Background technology
The electronic equipment of most of aircrafts uses boost type air circulation refrigeration system, and the system is directly from starting power traction
Gas, it is separated from water device by primary heat exchanger, compressor, secondary heat exchanger, turbine and is passed through cockpit, finally outside discharge machine.
The system ensures cabin pressurization, increases expansion ratio of turbine, makes turbo driving steady, increases turbine service life.
The system needs larger engine bleed, adds systematic function panelty；Made using primary heat exchanger
For forecooler, the energy in most bleed is lost；Furthermore, it is necessary to ram-air is as in low-temperature receiver cooling heat exchanger
Air, there is also big systematic function panelty.
The content of the invention
In order to solve the above problems, meet the high-power electronic device system continued to develop, the present invention proposes a kind of weight
Amount is light, small to carrier aircraft performance impact, the environmental control system of the small electronic equipment forced air cooling of compensatory performance loss, at least solves above-mentioned
A problem present in background technology.
The environmental control system of electronic equipment forced air cooling of the present invention, including dissipated installed in the annular of at least one engine lip
Hot device, the annular radiator will quoted from the hot-air of engine successively by check valve, High Pressure Water Separator, control valve and
Supply to optical device in machine, the connected high speed fan of turbine Driven by Coaxial, the high speed fan is taken out after turbine
Wind end is provided with negative pressure cavity, and the negative pressure cavity connection accommodates the electronic housing of the electronic equipment of forced air cooling in need.
Preferably, the annular radiator includes two, is separately positioned at any engine lip, described unidirectional living
Door includes two, connects any of the above-described annular radiator, and the High Pressure Water Separator is connected after converging.
Preferably, in addition to separator, it is arranged in turbine and the machine between optical device.
Preferably, in addition to filter, it is arranged on described in separator in machine between optical device.
It is an advantage of the invention that：The high speed fan that engine bleed is coaxially worked by turbine drives is directly quoted, fully
Engine bleed energy is make use of, avoids relying on carrier aircraft power supply, increases turbine temperature drop and cooling system amount, increases the air inlet of turbine
Degree, reduce turbine size, and then reduce system weight；High speed fan is drawn through the air of electronic equipment, makes cold air and electricity
Forced-convection heat transfer is produced between sub- equipment, strengthens the radiating of electronic equipment, cancels ram-air, so as to reduce the compensatory of system
Performance loss.
