Description
Technical field
The present invention relates to helicopter field of air conditioning more particularly to one kind to go straight up to machine cooling system.
Background technique
Helicopter is to rely on to provide power in the form of rotating output shaft by turboshaft engine and pass through machine driven system
Directly drive the aircraft that rotor generates lift and propulsive force.It can complete vertical rise and fall, hovering, rotate in place, in many ways
To impossible flare maneuvers of a variety of conventional fixed-wing aircrafts such as flights.Furthermore it can also be using rotor certainly when engine cut-off
Turn characteristic and realizes safe falling.Therefore it uses very safe.It combines the excellent of vehicle and fixed wing aircraft
Point both can be used for transporting the military purposes such as soldier's equipment, air-to-ground attack, antitank, fire support, searching rescue, can also answer
It is typical dual-use product used in multiple civil fields such as transport, patrol, tourism, rescue, it is deep by the extensive of people always
Concern.
It is the same with fixed wing aircraft, helicopter be also required to high temperature, high humidity adverse weather condition under fly.It is empty to guarantee
Diligent personnel's normal physiological demand, improving the comfort of occupant's carriage and the normal work of cabin inner electronic equipment, helicopter also needs
Configure cooling cycle system.Especially modern military-civil helicopter largely uses high-power, high for the performance for improving the machine
Integrated level avionic device, these equipment will release amount of heat when working, it is ensured that electronic equipment works normally, it is necessary to and
When these heats are distributed, meanwhile, personnel are also higher and higher to the expectation of helicopter capsule driving comfort, all these
Mean that requirement of the modern advanced high-performance helicopter to cooling cycle system is higher and higher.
Foreign countries started to install cooling cycle system on helicopter the 1960s.Its cooling cycle system mainly wraps
Include evaporation circulating system and air circulation system.The air circulation system of engine bleed was fixed wing aircraft environmental control system at that time
The solution generallyd use, weight are also lighter than evaporation circulating system.Therefore, when developing helicopter environmental control system, Ren Mentong
It is often considered as air circulation system, but air circulation refrigeration system panelty is big, low efficiency.
From entire environmental control system performance perspective, with increasing for helicopter-mounted electronic equipment, the increasing of heat flow density
Big and attachment manufacturing process, system optimization and control technology progress, it is ensured that the normal work of electronic equipment, it is necessary in time
These heats are distributed.Meanwhile occupant is higher and higher to the expectation of helicopter capsule comfort.So traditional open type is empty
Gas circularly cooling is since the limitation of engine bleed amount is without being able to satisfy cooling requirement, and vapor cycle refrigeration system is high-effect
Refrigerating capacity can satisfy this cooling requirement.Increase in addition, engine bleed will cause fuel combustion, the exhaust gas of discharge also can
Cause certain atmosphere pollution.
With the continuous development of airborne evaporation circulating cooling technology in recent years, system refrigerant leakage and reliability are poor etc.
Problem has obtained preferable solution, and with its refrigerating capacity is big etc., advantages are gradually used by helicopter evaporation circulating cooling scheme,
On helicopter application also more and more attention has been paid to.
