In recent years, with the continuous improvement of environmental protection regulations and the continuous enhancement of social environmental awareness, in the transportation field, people's requirements for engine energy saving, safety and comfort have further increased, and engine thermal management systems have received extensive attention from various research institutions. The focus of research on engine heat exchange is to improve the level of engine thermal management. The so-called engine thermal management system integrates the engine cooling system, the external aerodynamic system, the lubrication system and the vehicle internal air conditioning system from the perspective of system integration and overall, and performs effective overall management and control through the heat in the engine. So as to achieve the goal of improving engine fuel economy, reducing harmful emissions, and improving car comfort. In addition, the thermal management system is directly related to the reliability and stability of the engine under full working conditions. Therefore, the realization of intelligent control of the engine thermal management system can improve engine economy, emission levels, and operational reliability. And stability have strong reference significance.

    At present, the engine cooling system is considered to be the most important part of the engine thermal management system. The quality of the cooling system design is directly related to the heat dissipation capacity of the engine, which in turn affects the reliability of the engine's operation. Traditional engine cooling systems are usually designed based on the heat dissipation conditions at the worst operating conditions. In most cases, the engine runs under partial load conditions. At this time, the actual heat dissipation of the cooling system has exceeded the actual heat dissipation requirements of the engine. The heat loss and mechanical loss of the engine are aggravated, and the effective power is reduced.

    In order to solve the problems of high energy consumption and poor thermal management efficiency in the engine thermal management system, Mingguan Electric has conducted scientific research and technical research on the intelligent and controllable thermal management system. From the system integration level, intelligent thermal management refers to the intelligent and controllable collaborative optimization management of the heat of multiple systems such as the engine cooling system, air conditioning system, lubrication system, and supercharging system. From the component level, it refers to the effective management of heat through the research of many components such as water tank radiator, cooling fan, water pump, cooling medium, body material and processing performance. After years of unremitting efforts, Mingguan Electric finally realized the transition from passive management to active management of engine heat. The heat exchange solution of Chireng's Butler was born.

    Mingguan Electric’s smart cooling housekeeper solution is a set of variable-speed electric water pumps, electronically controlled thermostats, electronic cooling fans, smart electric inverter air conditioners, smart car heating systems, special cooling oil for drive motors, power battery cooling systems and other A number of practical technologies and components, with the engine's intelligent cooling system as the core, are suitable for professional heat exchange solutions for modern passenger cars, trucks and other commercial vehicles. The basic design principle of Mingguan's "Smart Cool Butler" heat exchange solution is to replace mechanical parts with electric parts and intelligent control instead of mechanical control to realize intelligent engine heat exchange. Regardless of the overall system integration or the component composition, Mingguan Electric has the core technology, patents, trademarks, and brands of the "Smart Cool Butler" solution, and realizes the integration of R&D, production, sales and after-sales service.

    Application of the heat exchange solution of Zhi Leng Big Butler

    The intelligent engine cooling technology, the core technology of Mingguan Intelligent Cooling Manager, has been selected into the sixth batch of "National Key Energy-saving Technology Promotion Catalog" by the National Development and Reform Commission, which has attracted widespread attention from the industry. The transformation and application of engine intelligent cooling technology has produced "engine intelligent cooling system" products.

    At present, relying on the "Smart Cool Butler" heat exchange solution, Mingguan Electric's engine intelligent cooling system and other series of products have been applied in batches to commercial vehicles under dynamic conditions in cities such as Beijing Public Transport and Suzhou Public Transport, and data obtained from tracking and monitoring It is shown that it not only realizes the active control and management of engine heat, but also greatly improves the heat utilization efficiency, improves the engine fuel economy, and the engine's comprehensive fuel-saving rate reaches about 10%.

    Smart Cool Manager is a comprehensive engine thermal management system. With the help of the "Smart Cool Butler" heat exchange solution, the optimal goal of precise control of engine water and air temperature and intelligent heat dissipation can be achieved, and the maximum utilization of engine fuel economy and thermal management can be achieved. With the deepening of technology research and development, Mingguan’s “Smart Cool Butler” heat exchange solution has also been applied to heat dissipation of new energy buses to meet the needs of motor heat exchange and improve the safety of motor operation.
