The importance of heat dissipation system for new energy vehicles

  With the oil price rising all the way, new energy vehicles are becoming more and more popular, the market is getting bigger and bigger, but the heat dissipation of new energy vehicles is also a huge problem. Many parts of new energy vehicles will generate a lot of heat in the process of operation. If this heat is not dissipated, it will have an impact on the whole automobile system. Overheating will affect the operation efficiency, affect lubrication and insulation, and even burn out the motor.

  If the electric motor of the new energy vehicle does not have good heat dissipation. In continuous operation, it is easy to overheat. After the temperature continues to rise, the resistance inside the motor will also increase, and the efficiency and output of the motor will drop sharply at this time. High temperature will also affect the internal lubrication and insulation of the motor, and in extreme cases, it may even burn out the motor. The motor water cooling system of new energy vehicles is usually not independent, but with the battery pack, as well as the cooling of the electric control system, to form a complete thermal management system.

  In the inside of the motor housing, there are similar to the water channel inside the cylinder block of the internal combustion engine, the coolant flow through the drive of the water pump in the middle, so as to achieve the effect of heat dissipation. Of course, the water cooling system should take into account the cooling of the battery pack and the driving motor. Some thermal management systems are also connected with the air conditioning and electric control system, which involves multiple subsystems and makes the design more complex.

  The water cooling system also has the benefit of coordinating the use of heat from the vehicle for better thermal management. Some models, for example, are designed to use the heat emitted by the motor to keep the battery pack warm.
