The invention discloses a comprehensive environmental control / liquid cooling heat energy management system without a ramjet inlet, belongs to the field of aircraft-carried equipment, and particularly relates to improvement on the comprehensive environmental control / liquid cooling heat energy management system without the ramjet inlet. The system consists of a two-wheel type high-pressure dehydration and refrigeration component, a liquid cooling system and a fuel system, wherein the high-pressure dehydration and refrigeration component is coupled with the liquid cooling system through an air-liquid heat exchanger; the air-liquid heat exchanger is positioned on the downstream of an air compressor outlet in the high-pressure dehydration and refrigeration component and is positioned between a shut-off valve and an expansion box in the liquid cooling system; the liquid cooling system is coupled with the fuel system through a liquid-fuel heat exchanger; and the liquid-fuel heat exchanger is positioned between the expansion box and a skin radiator in the liquid cooling system. Through the system, the performance compensation loss of the refrigeration system is reduced, the dehydration and refrigeration efficiency of the refrigeration component is improved, the influence on the flight performance of an aircraft is effectively reduced, the aircraft fuel efficiency is increased, and the aircraft economy is good.

Description

technical field [0001] The invention belongs to the field of aircraft airborne equipment, and in particular relates to the improvement of a comprehensive environment control / liquid cooling thermal energy management system for a non-ramming air inlet. Background technique [0002] The shortcomings of current technology are mainly manifested in the following aspects: [0003] On the one hand, the refrigeration systems currently used on aircraft mainly include air circulation-based environmental control systems and liquid circulation-based liquid cooling systems. The former is generally used for ventilation and cooling of cockpits and electronic equipment, while the latter is mainly used for electronic equipment with large thermal loads. cooling. These two refrigeration systems both use air-to-air heat exchangers or air-to-liquid heat exchangers to transfer the heat load of the cockpit or electronic equipment to the outside atmosphere, which will lead to an increase in the com...

Problems solved by technology

These two refrigeration systems both use air-to-air heat exchangers or air-to-liquid heat exchangers to transfer the heat load of the cockpit or electronic equipment to the outside atmosphere, which will lead to an increase in the compensatory loss of the performance of the refrigeration system and an increase in the flight resistance of the aircraft. and reduced flight performance

[0004] On the other hand, as the flight altitude increases, the cooling load of the environmental control system becomes smaller and the heating load becomes larger, and the thermal load of large electronic equipment is in a full-power working state at high altitude, which requires the largest cooling capacity. The explanation is simple The 1+1 has the problem of insufficient utilization of the cooling capacity of the refrigeration system, indicating that the current system design does not consider the feasibility of using part of the cooling capacity of the liquid cooling system to cool the air of the environmental control system as the flight altitude increases
