Abstract

The invention discloses a three-wheel pressure-boosting refrigerating and liquid cooling composite thermal energy managing system, belonging to the field of airplane airborne laser equipment, relating to an improvement on a composite environmental control/liquid cooling thermal energy managing system. The invention is composed of a three-wheel high pressure dehydrating refrigerating assembly, a liquid cooling system and a fuel system, wherein the high pressure dehydrating refrigerating assembly and the liquid cooling system are coupled by an air-liquid heat exchanger; said air-liquid heat exchanger is on downstream of the turbine in the high pressure dehydrating refrigerating assembly, and between an expansion tank and an electric heater in the liquid cooling system; the liquid cooling system and a fuel system are coupled by a liquid- fuel heat exchanger; said liquid- fuel heat exchanger is between an aircraft skin heat radiator and sov shutoff valve in the liquid cooling system. The invention lowers the compensation loss for the cooling system, and raises dehydration and cooling effect for the refrigerating assembly, and effectively lowers influence on flight performance of the aircraft, and raises the fuel efficiency of the aircraft such that the economy of the aircraft is good.

Description

technical field [0001] The invention belongs to the field of aircraft airborne equipment, and in particular relates to the improvement of the design configuration of a comprehensive environmental control / liquid-cooled thermal energy management system without a ram 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 a...

AI Technical Summary

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 design configuration 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
