Refrigerant returns to compressor 10 after gas-liquid separator 11, completes a heating circulation.In power source system, from main drive
The coolant liquid of the cooling liquid outlet outflow of motor 7 passes through electric machine controller 6, electric water pump 5, and inflow heat exchanger branch, high temperature is cold
But liquid exchanges in Intermediate Heat Exchanger 12 with refrigerant progress heat, i.e., recycles electromotor high-temperature waste heat by Intermediate Heat Exchanger 12,
To be supplied to heat pump air conditioning system heating, system capacity utilization efficiency is improved.
The utility model has the advantages that
No matter electric motor coach in traveling or Vehicular charging, can be allocated the heat in system, realization pair
The integrated thermal management of power source, air-conditioning system changes script motor but only by the mode of wind-cooling heat dissipating, avoids frequency
Motor temperature rise under the extreme cases such as numerous brake, climbing is excessively high, to influence the service life of motor, has effectively recycled motor and has existed
The high temperature waste hot generated under high load realizes Waste Heat Reuse, improves heat pump air conditioning system efficiency.
What needs to be explained here is that: in the absence of conflict, those skilled in the art can according to the actual situation by
