The Engine cooling system is to keep the engine in an appropriate temperature range under all operating conditions. The cooling system should not only prevent the engine from overheating, but also prevent the engine from overcooling in winter. After the engine is cold-started, the cooling system should ensure that the engine heats up quickly and reach the normal operating temperature as soon as possible. The cooling system is an important system to maintain the normal temperature and ensure the normal operation of the engine.
The water cooling system of the engine is a forced circulation water cooling system, which uses the water pump to increase the pressure of the coolant and force the coolant to circulate in the engine. Such systems include a water pump, radiator, cooling fan, thermostat, water jackets in the engine block and cylinder head, and other additional devices.
The forced circulation water cooling system is to pressurize the cooling liquid of the system with a water pump to flow in the water jacket. The cooling water absorbs heat from the cylinder wall, the temperature rises, and the hot water flows upwards into the cylinder head, and then flows out from the cylinder head and enter the radiator. Due to the strong wind blowing of the fan, the air flows through the radiator at high speed from front to back, continuously taking away the heat of the water flowing through the radiator. The cooled water is re-pumped into the water jacket from the bottom of the radiator by a water pump. Water circulates continuously in the cooling system.
The fan is to blow air through the radiator when the fan rotates to enhance the heat dissipation capacity of the radiator and speed up the cooling rate of the coolant.
The radiator core is the core part of the radiator, which plays a major role in heat dissipation. The radiator core is composed of tubes and fins, upper and lower mainboard. Because it has sufficient heat dissipation area, it can ensure that the necessary heat is dissipated from the engine to the surrounding atmosphere. Moreover, the radiator core is made of extremely thin metal and its alloy with good thermal conductivity, which can make the radiator core achieve the highest heat dissipation performance with the smallest quality and size. There are many types of radiator cores, such as tube-fin type, tube-band type shown below.
