As improvement, be provided with the electric cabinet metal shell that shields of sealing at electric power conversion apparatus and electrical control part, existing water-proof function has dust reduction capability again and strengthens the electric insulation function.
As further improvement, the top inner surface of described electric cabinet metal shell has been carried out heat insulation protection, and the heat that can effectively intercept solar radiation imports in the electric appliance box, and all there is better heat radiating effect on all the other each surfaces simultaneously.
As further improvement, described electric cabinet metal shell, condenser casing and evaporator shell all are fixed on and form as a wholely on two " Contraband " type air conditioner shells, are provided with upending frame on shell, open and hang and convenient transportation.
As further improving again, also be provided with the high-voltage power-line that is connected with inverter power supply device and electrical control part in the described cool metal pipeline, power line is cooled off, can shield the electromagnetic interference that high-voltage power-line produces simultaneously, improve the security of electric motor coach.
Compared with prior art, air conditioner of electric motor coach of the present invention can partly cool off supply unit in time owing to being provided with the cool metal pipeline, improve the reliability of electric elements, each several part is adopted the existing water-proof function of shell, dust reduction capability is arranged again, can shield simultaneously the electromagnetic interference that high-voltage power-line produces, improve the security of electric motor coach.

The specific embodiment
The present invention is further described below in conjunction with drawings and Examples.
Please refer to Fig. 1 to shown in Figure 2, air conditioner of electric motor coach of the present invention, its structure comprises air conditioner housing 9 and is arranged at condenser core 1 in the air conditioner housing 9, condensation fan 2, inverter power supply device 3, compressor 4, electric cabinet metal shell 5, evaporation fan 6, electrical control part 7, evaporator core 8, pipeline 10, evaporator shell 11, condenser casing 12, expansion valve 13 and cool metal pipeline 14, evaporator core 8 is positioned at the mid portion of air conditioner housing 9, condenser core 1 is positioned at the front end of air conditioner housing 9, compressor 4, electric power conversion apparatus 3, electrical control part 7 is positioned at the rear portion of air conditioner housing 9; Described compressor 4 connects condenser core 1, and condenser core 1 connects evaporator core 8, evaporator core 8 connects compressor 4 again and constitutes a circulatory system successively.Described evaporation fan 6 is positioned at a side of evaporator core 8, condensation fan 2 is positioned at condenser core 1 one sides, expansion valve 13, evaporator core 8 and evaporation fan 6 are positioned at evaporator shell 11, condenser core 1 and condensation fan 2 are positioned at condensation shell 12, be provided with cool metal pipeline 14 between evaporator core 8 and electric power conversion apparatus 3 and electrical control part 7, cool metal pipeline 14 is connected evaporator core 8 with electric power conversion apparatus 3 and electrical control part 7.
Wherein, described electric power conversion apparatus 3, compressor 4, electrical control part 7 are installed in the electric cabinet metal shell 5, in the present embodiment, electric cabinet metal shell 5 adopts aluminium alloy, electric cabinet metal shell 5 can fall the electromagnetic interference shield that AC power produced in electric power conversion apparatus 3 and the electrical control part 7, described compressor 4 uses AC power to drive, and electric power conversion apparatus 3 changes into power frequency AC with the dc source of electric motor coach.One port of cool metal pipeline 14 is located on the evaporator shell 11, the another port is located on the electric cabinet metal shell 5, cool metal pipeline 14 can import the cold air in the evaporator shell 11 in the electric cabinet metal shell 5, can partly cool off supply unit in time, improve the reliability of electric elements, can shield simultaneously the electromagnetic interference that high-voltage power-line produces, improve the security of electric motor coach.Described electric cabinet metal shell 5, condenser casing 12 and evaporator shell 11 all are fixed on and form as a wholely on the air conditioner shell 9, make to open and hang and convenient transportation.
Specific implementation process of the present invention is as follows: compressor 4 sucks the gaseous refrigerant of the low-temp low-pressure in evaporator core 8 exits, and the gas that it is compressed into HTHP is discharged compressor 4; The overheated gaseous refrigerant of HTHP enters by the road and 10 enters condenser core 1, and the forced flow wind speed of air cools off condenser 1 when utilizing car to advance, and cold-producing medium is condensed into liquid state by gaseous state, and emits a large amount of heat energy; After the higher sub-cooled liquid refrigerant of temperature and pressure was passed through expansion valve 13, pressure and temperature sharply descended, and it is big that volume becomes, and discharges expansion valve 13 with vapour-liquid two-phase state; Vapour-liquid two-phase state cold-producing medium 19 enters evaporator core 8 by the road, therefore the cold-producing medium boiling point is far below temperature in the evaporator core 8 time, so cold-producing medium flashes to gaseous state by liquid state, a large amount of heats that absorb surrounding air in evaporation process, the generation effect on moisture extraction that cools, by evaporation fan 6 cold air is blown in the electric motor coach again, thereby reach the purpose of cooling in the car; A part of in addition cold air then imports in the metal shell 5 by cooling pipe 14 supply unit is partly cooled off.Then, the gaseous refrigerant of this low-temp low-pressure enters compressor 4 again and restarts another circulation.What said process went round and began again goes on, and just can reach the purpose that reduces the evaporator core ambient air temperature, and provides cold air by evaporation fan 6 for electric motor coach.
