The function of the cooling room system is to take away the engine heat generated by the combustion, so that the engine maintained in the normal operating temperature range. Engine in accordance with the cooling method can be divided into air-cooled engine and water-cooled engine, air-cooled engine is driven by the engine fan and the vehicle when the air flow to cool the engine; water-cooled engine is by the cooling water in the engine cycle to cool engine. Regardless of the way in which the cooling system, the normal cooling system must ensure that the engine in a variety of driving environment will not overheat.
Can be through the coolant circulation, the excess heat out of the engine to prevent overheating of the system. In the water-cooled engine, including water jacket, water pump, water tank and thermostat. In the electromechanical equipment industry, the cooling system is an extremely important part of the cooling operation of the electrical and mechanical devices is concerned about the safe operation and service life, is also easily overlooked in a weak part, such as in the high-power power electronic device cooling system is very The necessary ancillary equipment. By the coolant cycle, the excess heat will be removed from the engine to prevent overheating of the system. In the water-cooled engine, including water jacket, water pump, water tank and thermostat.
The temperature of the cylinder in the combustion of the combustible mixer is as high as 2073-2273 K. The parts (such as cylinder block, cylinder head, piston, valve, etc.) which are in direct contact with the high temperature gas, if not cooled in time, Thermal expansion and damage the normal gap, or because of the failure of the lubricating oil at high temperatures and stuck: the machine will be due to high temperature and its mechanical strength caused by reduced or even damaged.Therefore, in order to ensure the normal work of the engine, must work in high temperature conditions Cooling the engine must be moderate.
If the engine cooling is insufficient, will make the cylinder inflated enough and premature and deflagration and other combustion is not normal phenomenon, the engine power will drop, and the engine parts will be due to poor lubrication and accelerated wear and tear. But if the cooling over, on the one hand because of excessive heat dissipation, is converted into useful work to reduce the heat, on the other hand because the mixed breath and cold cylinder contact, so that the original gas has been condensed and flow to the crankcase , The engine will not only increase the fuel consumption, and make the oil thinning affect the lubrication, the result will also reduce the engine power, wear and tear.Therefore, the cooling system is to make the task of the start To obtain an appropriate cooling to maintain the optimum working temperature range.
