In order to overcome above-mentioned the deficiencies in the prior art, the invention provides that a kind of volume is little, the ground cooling apparatus of airborne electronic apparatus of compact conformation, easy to use, good cooling results, dependable performance.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: a kind of ground cooling apparatus of airborne electronic apparatus, mainly comprise electric cabinet, compressor, air-cooled condenser, axial flow blower, evaporator, described evaporator is formed by two groups of serial connections, one group of evaporator links to each other with the direct current centrifugal blower, and the muffler of this group evaporator links to each other with unidirectional valve; Another group evaporator links to each other with electric heater, and the muffler of this group evaporator links to each other with evaporating pressure regulating valve.
Be provided with single-chip computer control system in the described electric cabinet.
This device adopts the natural air cooled but two kinds of types of cooling of compression mechanism cold-peace, when ambient temperature is low, directly Cryogenic air is sent into electronic equipment cooling, economical operation by the direct current centrifugal blower; When ambient temperature was high, compressor start was sent the low temperature wind of two groups of evaporators generations into electronic equipment by the direct current centrifugal blower and is carried out heat exchange.
Because adopt above technical scheme, beneficial effect of the present invention is as follows:
1, adopts two groups of evaporators, can make wind pushing temperature low, reliable operation.
2, adopt the direct current centrifugal blower, its volume is little, and airflow pressure is big, can satisfy the needs of fast cooling, and the cooling device volume is corresponding to diminish, and compact conformation moves easy to use.
3, adopt single-chip computer control system can control and show air themperature, air mass flow, air pressure.
4, adopt evaporating pressure regulating valve and unidirectional valve, improved the reliability of device, guarantee the trouble-free operation of refrigerating system, guarantee that the evaporating pressure of two groups of evaporators is constant, make system works stable.
This device volume is little, simple in structure, and wind pushing temperature is low, pressure is high, and cooling rate is fast, effective, can make the air environment stable performance, reliable operation, and the life-span prolongs.
