In the application of new energy battery motors, a certain amount of heat will be generated, so the direct cooling and direct heating machine of new energy vehicles is needed for heat dissipation and cooling. Then, how is the direct cooling and direct heating machine of new energy vehicles applied in the new energy vehicle industry? How is the direct cooling and direct heating machine of new energy vehicles composed?

The direct cooling and direct heating engine of new energy vehicles mainly includes radiator, coolant, water pump, fan and control device. The coolant circulates through the water pump to remove heat from the motor, battery and electronic control system, and then dissipates the heat into the air through the fan in the radiator to maintain the normal operating temperature of the vehicle.

• Radiator

The radiator is the core component of the direct cooling and direct heating engine of new energy vehicles, usually located at the front of the vehicle. Coolant flows from the engine or electric motor, exchanging heat indirectly with the ambient air through the radiator’s tiny tubes and fins. At the same time, the fan will accelerate the air flow and improve the cooling effect.

• Coolant

Coolant plays a very important role in direct cooling and direct heating of new energy vehicles. It can not only absorb heat, but also prevent corrosion and fouling inside the direct cooling and direct heating machine of new energy vehicles. Common coolants are generally mixed liquids composed of water, anti-corrosion agents, antifreeze, etc. The choice of coolant should take into account the stability at high temperature and the antifreeze performance at low temperature.

• Water pump and fan

The water pump is the power source of the direct cooling and direct heating engine of the new energy vehicle, and keeps the coolant flowing by driving the circulating water flow. The fan is mainly responsible for increasing air flow and improving heat dissipation. When the temperature rises, the water pump and fan will start automatically to keep the direct cooling and direct heating machine working normally.

• Control device

In order to better control and manage the direct cooling and direct heating machines of new energy vehicles, new energy vehicles are equipped with intelligent control devices. The device can monitor parameters such as temperature, flow and pressure in real time through sensors, and adjust the flow of coolant and the speed of the fan in time as needed. This intelligent management system can ensure the operation of direct cooling and direct heating machines and improve energy utilization.
