The best thermal solution for new energy industry
New energy vehicle is a project supported by China. It has developed rapidly in recent years. The whole vehicle technology and parts technology of electric vehicle are also constantly innovated, and new technologies and processes are constantly introduced. In the field of heat dissipation , the key point of heat dissipation of electric vehicles lies in the heat dissipation of power battery packs and controllers. Doing a good job in thermal design of these two pieces is also a necessary guarantee for the stable operation of electric vehicles.
The power batteries of electric vehicles generally include cylindrical batteries, square batteries and soft pack batteries. Different types of batteries use different thermal design; There are flat plate liquid cooling , serpentine tube water cooling plate and slot liquid cooling . Through thermal design and thermal simulation, the data meet the heat dissipation design standards.
The application range of liquid cooling plate is very wide. With the development of liquid cooling technology in recent years, the utilization rate of liquid cold plate is higher, gradually replacing some original themral products of natural cooling and forced air cooling. In the field of new energy, liquid cooling is used for inverter heat dissipation of photovoltaic power generation, converter heat dissipation of wind power and power battery pack heat dissipation of electric vehicle. The design of liquid cooling plate is also various, and the water channel design of liquid cold plate is also different.
The thermal management system of electric vehicles assists in driving by maximizing the utilization of battery energy. By carefully reusing the heat energy in the vehicle to the air conditioning and batteries inside the vehicle, thermal management can save battery energy and extend the vehicle's driving range, with its advantages particularly significant in extreme cold and hot temperatures. The thermal management system of electric vehicles mainly includes high-voltage battery management system (BMS), battery cooling plate, battery cooler, high-voltage PTC electric heater, and heat pump system according to different vehicle models.
