Description
Technical field
The present invention relates to the aircraft airborne refrigeration technology field, be specifically related to a kind of airborne liquid cooling system for aircraft load refrigeration.
Background technology
Along with a large amount of utilizations of air environment, the heat load of electronic equipment also improves constantly, and the operating ambient temperature of electronic equipment also has influence on its reliability and life-span.So air environment is more and more higher to the requirement of the refrigerating capacity of cooling system on the one hand; On the other hand, due to the particularity of airborne equipment, also very strict to the restriction of the volume of cooling system, weight, electrical power.So airborne liquid cooling system should meet the requirement that refrigerating capacity is large, meet again the requirement that volume is little, lightweight, consumption of electric power is little.
Because electronic equipment on aircraft is many, produce heat awing large, by air and cooling fluid, the heat exchange in heat exchanger is transferred to ambient atmosphere by the thermal force of electronic equipment to airborne liquid cooling system.In current airborne liquid cooling system, for the air general using aircraft ram-air of heat exchange, and the air inflow of ram-air often is subject to the restriction of aircraft flight speed, aircraft altitude and air intake duct, generally can not meet the requirement of large heat exchange amount.
Summary of the invention
In order to overcome existing issue, the invention provides a kind of airborne liquid cooling system for aircraft load refrigeration, be not subject to aircraft ram-air air inlet quantitative limitation, and reach the requirement of larger refrigerating capacity.
For achieving the above object, the present invention has adopted following technical scheme: a kind of airborne liquid cooling system for aircraft load refrigeration, comprise the liquid reserve tank, water pump and the heat exchanger that are connected to aircraft load import and export two ends and form the liquid circulation loop, the export pipeline of described aircraft load is communicated with the entrance of the ice-storage box be arranged in parallel, heat exchanger respectively; The outlet of described ice-storage box is communicated with the entrance of liquid reserve tank by the second snap joint, and the entrance of ice-storage box is communicated with the export pipeline of described aircraft load by the first snap joint.
For can according to the variation of aircraft load request refrigerating capacity regulate the ice-storage box of flowing through cooling fluid flow, the entrance pipe of described ice-storage box is provided with flow control valve.
Further, the top of described liquid reserve tank be provided with expansion drum with for the automatic exhaust steam valve of air-discharging.
The present invention is at the two ends of the heat exchanger in liquid circulation loop and connect an ice-storage box, water pump imports the cooling fluid met the demands in liquid reserve tank in the aircraft load, cooling fluid temperature after aircraft load heat exchange raises, enter respectively heat exchanger in parallel and ice-storage box from its outlet, return in liquid reserve tank after reducing by the temperature that makes cooling fluid after heat exchange, reach the aircraft load is carried out to cooling purpose.
The top of liquid reserve tank and the filling of expanding are communicated with, and can maintain the constant pressure of liquid reserve tank inside, and the automatic exhaust steam valve that top arranges is for getting rid of the air in airborne liquid cooling system, improves refrigeration.For monitoring machine carrier fluid cooling system better, can be on the entrance pipe of aircraft load set temperature transducer and pressure sensor, simultaneously at the inner set temperature transducer of liquid reserve tank, thus can be when airborne liquid cooling system operation real-time monitoring system temperature and pressure value.
Can be provided with electric heating in liquid reserve tank, when coolant temperature is too low, heated cooling fluid is to the temperature required.The top of liquid reserve tank and bottom are respectively arranged with liquid injection port and leakage fluid dram, are used for supplementing cooling fluid and get rid of cooling fluid.
The two ends that enter, export of ice-storage box are connected with the outlet of aircraft load, the entrance of liquid reserve tank by the first snap joint, the second snap joint respectively.When ice-storage box carries out ice-reserving, first snap joint of outwarding winding, the second snap joint, disconnect itself and liquid circulation loop, and be connected with the ground ice storage unit by the first snap joint, the second snap joint; After the ice-storage box ice-reserving finishes, outward winding the first snap joint and the second snap joint, disconnect itself and ground ice storage unit.And by the first snap joint, the second snap joint and liquid circulation circuit communication, the aircraft load is carried out comparatively fast cooling, according to the size of ice-reserving amount, can meet the interior cold requirement of certain flight time of aircraft.By the flow control valve on the entrance pipe of regulating ice-storage box realize according to the variation of aircraft load request refrigerating capacity regulate the ice-storage box of flowing through cooling fluid flow, can bring into play to greatest extent the ability of ice cold-storage, thereby reach the purpose of accurate refrigeration.
So this is implemented novel ice-storage box and has realized the quick switching of interface by snap joint, has facilitated the ice-reserving of aircraft when ground, and carry out cooling purpose after taking off.
Beneficial effect of the present invention is embodied in:
1) due to the two ends of the heat exchanger in the liquid circulation loop and connect an ice-storage box, by the high temperature coolant after aircraft load heat exchange, carry out respectively carrying out in ice-storage box and heat exchanger cooling, freeze and made up the deficiency of heat exchanger refrigerating capacity by ice-storage box, can in the aircraft flight process, consume under the condition of less airborne electrical power, meet the requirement of larger refrigerating capacity.
2) this airborne liquid cooling system is restricted in aircraft ram-air air inflow, and then, in the situation of restriction heat exchanger heat exchange amount, has met the requirement of larger refrigerating capacity by the ice-storage box increased.
3) ice-storage box of this airborne liquid cooling system can complete ice-reserving on ground, in the aircraft flight process, provides refrigeration, and aircraft flight returns to ground after finishing and again carries out ice-reserving.This mode takes full advantage of the characteristics of aircraft flight, and can, according to the size of aircraft non-stop flight time match design ice-storage box, realize the optimization of system effectiveness.
4) this system is provided with flow control valve in ice-storage box import department, can regulate according to the variation of load in the aircraft flight process flow of the ice-storage box cooling fluid of flowing through, when load less, when heat exchanger can meet the demands by the ram-air heat exchange, can close adjuster valve fully, save the cold of ice-storage box, can bring into play to greatest extent the ability of the cold-storage of ice-storage box.
