Around 2000, China's passenger car market gradually completed the transition from traditional cooling systems to intelligent cooling systems. In 2007, at the "Car Rear-mounted Engine Cooling Fan Drive Technology Seminar" held by the China Highway Society Bus Branch, some experts pointed out that the traditional engine cooling system itself consumes more than 10% of the engine power, how to reduce cooling. The system's own power consumption, how to make the engine play a higher efficiency, has become a bottleneck in the industry at that time. At this meeting, the participants generally believed that the commercial vehicle engine cooling system needed to be upgraded. Compared with the passenger car market, the intelligent cooling mode represented by the engine intelligent cooling system will eventually become the mainstream of future commercial vehicle engine cooling.
It is a consensus that the vehicle engine needs to dissipate heat. In the early stages of cooling system development, meeting vehicle cooling requirements is the design goal of the engine cooling system. With the development of modern society and the advancement of automobile technology, the drawbacks of the traditional engine cooling system are becoming more and more obvious, and it is increasingly unable to meet the requirements of modern automobiles. It can be said that Hyundai Motor not only requires its cooling system to meet the heat dissipation requirements, but also has higher heat dissipation efficiency, better heat dissipation effect, and lower heat dissipation energy consumption. And this is the essence of "smart cooling" - cooling energy saving, cooling intelligent!
Intelligent cooling relies on the engine intelligent cooling system. Taking the ATS system of the Vision Technology as an example, the intelligent cooling system of the engine is a new type of cooling mode that is different from the traditional engine cooling system. It solves two drawbacks of the traditional engine cooling system: one is the binary heat transfer problem, and the other is the self-work. High consumption. Its main features have two aspects: First, the structure, the engine intelligent cooling system uses the water tank and the intercooler in parallel arrangement structure, each heat exchanger has an independent cooling air duct. The second is the drive. The engine intelligent cooling system belongs to the electronic control system. The cooling fan is intelligently driven by the ECU controller to dissipate heat on demand and save energy. No longer driven by the engine belt. These two changes have become the basis for the "smart cooling" of the engine intelligent cooling system.
The fundamental method of intelligent cooling is intelligent control. Now the comprehensive development of electronic technology and control technology provides a good technical foundation for intelligent heat dissipation of commercial vehicles. The intelligent controller with electronic circuit control technology as the core and single chip as the carrier has been widely used in the field of automobile manufacturing. The engine intelligent cooling system integrates heat exchanger, cooling fan, intelligent controller, sensor, wiring harness, display and mechanical components. The temperature sensor distributed in each inlet and outlet of the heat exchanger monitors and transmits the temperature value to the ECU controller in real time. The ECU controller has an optimal temperature control strategy for the engine operation, and controls the operation state of the cooling fan on, off, and infinite acceleration according to the actual temperature value. The heat dissipation of the cooling system is only related to the heat dissipation requirements of the engine. It is no longer related to the engine speed. It truly realizes the engine's on-demand heat dissipation and the water and gas temperature intelligent constant temperature to ensure that the engine is always in the best working condition.
Intelligent cooling comes from technological advancement, and it is also derived from the increasing recognition of the concept of environmental protection and emission reduction. Through the engine intelligent cooling system to achieve intelligent cooling of commercial vehicles, how much energy consumption such as oil and natural gas is saved every year?! This is a technology update trend that benefits the society and benefits future generations, and is also an inevitable trend of future commercial vehicle cooling.
