Detailed description of the invention
With reference to Figure of description 1 and accompanying drawing 2, a kind of parallel flow heat exchange air conditioner for electric motor coach of the present utility model is described in detail below.
A kind of parallel flow heat exchange air conditioner for electric motor coach of the present utility model, its structure comprises evaporator core 4, motor driven compressor 1, condenser core, described motor driven compressor 1 connects condenser core, condenser core connects evaporator core 4, evaporator core 4 connects motor driven compressor 1 again and forms a circulating system successively, evaporation fan 6 is had in evaporator core 4 arranged outside, condenser core top is provided with condensation fan 10, described condenser core is parallel-flow heat exchanger core body 2, described parallel-flow heat exchanger core body 2 is arranged in condenser cover 11 with condensation fan 10, 2 rear portions of parallel-flow heat exchanger core body are provided with motor driven compressor 1, the rear portion of motor driven compressor 1 is provided with evaporator core 4 and evaporation fan 6, liquid storage dryer 3 and expansion valve 12 is provided with between described parallel-flow heat exchanger core body 2 and evaporator core 4.
Gas-liquid separator 5 is provided with between described evaporator core 4 and motor driven compressor 1.For gas-liquid separation and dedusting, the gas of process containing a small amount of lime set, realizes lime set and reclaims or gas phase purifying.
Described parallel-flow heat exchanger core body 2 is obliquely installed, and parallel-flow heat exchanger core body 2 bottom is provided with mouth 9 windward, and described mouth windward 9 is arranged on platform downward-sloping from front to back.Automobile is advanced, and adjoint air intake is parallel enters in parallel-flow heat exchanger core body 2, and the heat that parallel-flow heat exchanger core body produces is taken away via condensation fan 10 with air intake, utilizes natural wind to realize heat and exchanges.
Parallel-flow heat exchanger is the novel porous flat pipe heat exchanger of one grown up on the basis of pipe type heat exchanger, and the feature that it is efficient with it, compact, becomes the regeneration product that pipe type automotive air-conditioning condenser is desirable.
From weight, condenser core adopts parallel flow type structure, the light 50-80kg of weight ratio pipe type, but its consequence that high pressure can be brought too high.The major cause causing high pressure too high, for can have some liquid refrigerant in common parallel-flow heat exchanger core body 2 inside, makes parallel-flow heat exchanger core body 2 inner space diminish, finally causes high pressure too high.
Install a liquid storage dryer 3 additional below at parallel-flow heat exchanger core body 2, make liquid refrigerant be stored in herein, increase the inner space of parallel-flow heat exchanger core body 2, to reduce high-pressure.
The parallel-flow heat exchanger core body 2 of this configuration is more energy-efficient than tube-fin condenser, effectively can increase course continuation mileage.
When air-conditioning normally works, the high temperature that motor driven compressor 1 is discharged, high pressure refrigerant vapor, enter the parallel-flow heat exchanger core body 2 of air conditioning for automobiles, due to high temperature, the refrigerant vapour temperature of high pressure is higher than the air themperature outside car, by condensation fan 10, the heat of refrigerant vapour in parallel-flow heat exchanger core body is taken away by car outer air, make high temperature, the refrigerant vapour condensation of high pressure becomes the highly pressurised liquid of higher temperature, flow into independently liquid storage dryer 3, liquid storage dryer is except ensureing under various operating mode, sufficient refrigerant actv. is had to participate in outside circulation, more increase the inner space of parallel-flow heat exchanger core body, high-pressure is effectively reduced, make air conditioner refrigeration effect remarkable.By the throttling action of overexpansion valve 12, refrigerant becomes the fog-like body of low-temp low-pressure and enters the evaporator core 4 of air conditioning for automobiles, vaporize under level pressure, and the heat absorbed in evaporator core pipe outer air, the temperature of the car inner circulating air flowing through evaporator core is reduced and becomes cold air, send in car by evaporation fan 6, reduce the air themperature in car.Refrigerant vapour after vaporization, sucked by motor driven compressor 1 and compress, become again the refrigerant gas of high temperature, high pressure, enter the parallel-flow heat exchanger core body 2 of air conditioning for automobiles, automobile outer air enters in condenser cover 11 via ventilation inlet 8, mouth windward 9 is herein arranged on the platform of constant slope, the automobile adjoint air intake that advances is made to enter in parallel-flow heat exchanger core body 2, the heat that parallel-flow heat exchanger core body produces is taken away via condensation fan 10 with air intake, utilizes natural wind to realize heat and exchanges.The carrying out that this refrigerating cycle is gone round and begun again, just can make the temperature in car maintain comfortable temperature.
Except the technical characteristic described in specification sheets, be the known technology of those skilled in the art.
