Description
Technical field
The invention belongs to the aircraft airborne apparatus field, being specifically related to does not have an improvement that ram air duct is comprehensively encircled control/liquid cooling thermal management systems design configuration to a kind of.
Background technology
The weak point that current techniques exists mainly shows in the following areas:
On the one hand; The refrigeration system of using on the current aircraft mainly comprises based on the environmental control system of wind circulation with based on liquid on-cycle liquid-cooling system; The former generally is used for the ventilation cooling of passenger cabin and electronic machine, and the latter is mainly used in the cooling of big thermal load electronic machine.These two refrigeration systems all use air-air heat exchanger or air-liquid heat exchanger that passenger cabin or electronic machine thermal load are transferred to ambient atmosphere; This will cause compensatory loss increase of performance of refrigerant systems and aircraft flight resistance to increase, and aircraft fuel oil and airworthiness reduce.
On the other hand; Along with flying height increases; The refrigeration load of environmental control system is more and more littler and to add thermal load increasing; And thereby the thermal load of large scale electronic equipment is in the full power operation state and requires refrigerating capacity maximum in the high-altitude, explains that there is the under-utilized problem of refrigeration system refrigerating capacity in simple 1+1 design configuration, shows that current system design not have to consider to increase along with flying height the feasibility of use partially liq cooling system refrigerating capacity cooler environment control system air.
Summary of the invention
The object of the invention: the present invention is primarily aimed at the not high problem of refrigerant system capacity degree of utilization that current aircraft exists; The comprehensive heat management design concept of two refrigeration systems is proposed; Utilize liquid-cooling system to shift air compressor heat of compression and fuel oil and fuselage air-flow design concept as heat sink metastatic electron equipment thermal load; Reduce the use amount of refrigeration system, realize satisfying low compensatory loss, the green refrigeration system design of aircraft cooling requirement ram air.
Technical scheme of the present invention is:
A kind of three-wheel boost type refrigeration and the comprehensive thermal management systems of liquid cooling; It is characterized in that; Form by three wheeled high pressure water separation regenerative air cycle cooling system cooling assemblies, liquid-cooling system and fuel oil system three parts; High pressure water separation regenerative air cycle cooling system cooling assembly and liquid-cooling system are through the coupling of air-liquid heat exchanger, and this air-liquid heat exchanger is positioned at the turbine outlet downstream in the high pressure water separation regenerative air cycle cooling system cooling assembly, in liquid-cooling system between expansion tank and electric heater;
