A car’s engine operates most efficiently at high temperatures, emitting less pollution and keeping its components in top condition. However, as a car burns fuel, it produces a surplus of heat. The job of the car’s cooling system is to allow the engine to quickly attain its maximum temperature, maintain that temperature during its use and release the excess heat into the air. The cooling system is composed of various parts the radiator, pressure cap, fan, pump, thermostat, hoses and overflow tank. The pump sends cooling fluid to the engine where it absorbs the engine’s heat. After exiting the engine, it runs by a thermostat. If the cooling fluid is below the maximum temperature, the thermostat stays closed and the fluid is re-routed back to the pump. However, if the fluid is overheated, the thermostat’s valve opens, routing the fluid through a radiator first. The radiator cools the fluid by releasing its heat to the air before returning it to the pump. Cars can have a liquid cooling system or an air cooling system, although most modern cars are liquid-cooled. With a cooling system based on liquid, fluid contained in pipes passes through the engine, absorbing heat while cooling the engine. If the fluid gets overheated, it’s routed through the radiator, which acts as a heat exchanger, releasing the surplus heat to the air. On the other hand, a cooling system based on air has aluminum fins surrounding the engine. When the engine gets overheated, fans blow air over the fins to conduct the heat away from the engine’s cylinder, cooling it down. Engines are heated in a similar way when starting up the car. The pump starts the process by sending fluid through the engine. As the fluid leaves the engine, if it hasn’t reached the minimum temperature, it needs to pass through a heater core before being re-routed to the pump. Originally Published Jun 21, 2011 Engine Cooling System FAQ What are the types of engine cooling systems? Vehicles can have either an air cooling system or a liquid cooling system. Most modern cars use liquid cooling systems. What are the parts of cooling system? The cooling system is composed of the radiator, pressure cap, fan, pump, thermostat, hoses and overflow tank. What is the purpose of a cooling system of an engine? The job of the car's cooling system is to allow the engine to quickly reach its maximum temperature, maintain that temperature during its use and release the excess heat into the air. What is the major cause of cooling system failure? Some of the biggest reasons cooling systems fail are too little coolant, a clog or other obstruction, a leak and a malfunctioning thermostat. Is it safe to drive with coolant light on? When your coolant light comes on, it means your coolant is pretty much depleted. Continuing to drive without coolant can lead to problems like the engine overheating or blown gaskets. You shouldn't drive for very long with your coolant light on; instead, pull off the road and let your engine cool down. Then refill the coolant reservoir as soon as possible. Then your best best is to head to an auto garage to determine why your coolant is low, according to May. 20, 2019 The function of engine cooling system is to keep the engine within the proper temperature range under all operating conditions. The cooling system must prevent the engine from overheating and prevent the engine from being too cold in winter. After the engine is cold-started, the cooling system also ensures that the engine heats up quickly and reaches the normal operating temperature as quickly as possible. The cooling system is an important system to maintain the normal temperature of the engine and ensure the normal operation of the water cooling system of the engine is a forced circulation water cooling system, that is, the pump is used to increase the pressure of the coolant, and the forced coolant is circulated in the engine. Such system includes water pump, radiator, cooling fan, thermostat, water jacket in engine block and cylinder head, and other forced circulation type water cooling system uses a water pump to pressurize the cooling liquid of the system to flow in the water jacket. The cooling water absorbs heat from the cylinder wall, the temperature rises, the hot water flows upward into the cylinder head, and then flows out from the cylinder head and into the radiator. Due to the powerful blowing action of the fan, the air flows through the radiator at a high speed from front to back, constantly taking away the heat of the water flowing through the radiator. The cooled water is pumped back into the jacket from the bottom of the radiator by the water pump. Water circulates continuously in the cooling function of the fan is to blow air through the radiator when the fan rotates, so as to enhance the heat dissipation capacity of the radiator and accelerate the cooling speed of the radiator core is the core part of radiator and plays a major role in heat dissipation. The radiator core is composed of a heat-dissipating tube, a heat sink, and upper and lower main pieces. Thanks to its sufficient heat dissipation area, it ensures that the necessary heat is dissipated from the engine to the surrounding atmosphere. Moreover, the radiator core is made of a extremely thin metal and alloy with good thermal conductivity, which enables the radiator core to achieve the highest heat dissipation effect with the minimum quality and size. There are many types of radiator cores, such as tube type, tube belt, and tube core type and so on. As shown in the figure, the most common ones are tube type and tube role of the thermostat is to automatically change the flow rate and circulation route of the coolant with the engine load and water temperature to ensure that the engine works at a suitable temperature, reducing fuel consumption and wear of the machine. The cooling water passes through the water pump-water jacket-thermometer- radiator, and is also pressed by the water pump into the water jacket. The water flow route is long and the heat dissipation intensity is large, which is called the large circulation of the water cooling system. The cooling water passes through the water pump-water jacket- thermometer without the radiator, but is directly pressed by the water pump into the circulation of the water jacket. The water flow route is short and the heat dissipation intensity is small, which is called a small cycle of the water cooling thermostat is generally placed at the water outlet of the engine. It is required that the amount of leakage of the thermostat is small, and the flow area is large when fully opened. Increasing the flow area of the thermostat can be achieved by increasing the lift of the thermostat valve and increasing the diameter of the valve. More advanced thermostats abroad increase the flow area by increasing the valve lift, which can reduce the problems caused by increasing the diameter of the thermostat valve and the tight seal. However, increasing the lift of the thermostat requires higher technical requirements for the thermostat. Some engines use two thermostats in parallel to increase the flow area of the thermostat. Iman Firman/ Periksa kondisi sistem pendinginan mesin dari mulai radiator sampai water pump. - Pada dasarnya cara kerja cooling system atau sistem pendingin mesin mobil cukup sederhana. Panas dari ledakan di silinder dan gesekan komponen mesin didinginkan oleh air yang dialirkan oleh pompa air water pump. Karena menerima kalor dari silinder, air pendingin ini akan menjadi panas. Air panas ini kemudian kembali didinginkan oleh radiator. Radiator melepas kalor dari air dengan bantuan angin yang melewati kisi-kisinya.

Nah, sistem pendinginan mesin terdiri dari banyak komponen. Berikut komponen di sistem pendingin mobil beserta fungsinya. Juni 13, 2019 Dapatkah kamu bayangkan, kenapa mesin-mesin penggerak pada kendaraan seperti pesawat terbang, kapal laut, dan kendaraan darat dapat menempuh perjalanan jauh. Atau, kenapa mesinmesin penggerak di industri dapat dioperasikan dalam waktu yang sangat lama tanpa segera mengalami kerusakan yang berarti? Tidak rusak karena perubahan deformasi perubahan struktur dari logam akibat panas yang ditimbulkan panas pembakaran. Itu karena mesin-mesin tesebut didinginkan. Coba bayangkan bila mesin-mesin tersebut tidak didinginkan, mesin pasti akan macet dan hancur karena panas. Hal ini dikarenakan pada mesin-mesin tersebut terdapat suatu rangkaian sistem yang menjaga agar tidak menjadi terlalu panas. Sistem tersebut di antaranya adalah sistem pendingin dan sistem pelumasan. Pada kerja mesin, energi panas atau kalor ditimbulkan oleh pembakaran bahan bakar dan udara di ruang bakar hanya 25% dari keseluruhan jumlah kalor yang dapat dimanfaatkan. Sisanya adalah 30% diserap oleh mesin itu sendiri yang kemudian perlu didinginkan 45% hilang bersama gas buang sisanya hilang karena adanya gesekan pada mesin itu sendiri Pembakaran di ruang bakar motor bensin dan motor diesel menghasilkan panas sekitar kurang lebih 2500° C, sehingga perlu didinginkan oleh sistem pendingin sampai suhu mesin mencapai suhu yang tepat. Suhu yang sesuai akan membuat kondisi operasional mesin maksimal, tahan lama, tanpa merusak komponen logam mesin, serta emisi gas buang yang dihasilkan dapat lebih baik bagi lingkungan hidup. Panas mesin yang tepat itu disebut dengan panas kerja mesin. Panas kerja itu sekitar 80° - 99° C. Sistem pendinginan dalam mesin kendaraan adalah suatu sistem yang berfungsi untuk menjaga agar temperatur mesin dalam kondisi yang ideal. Mesin pembakaran dalam melakukan proses pembakaran untuk menghasilkan energi dan dengan mekanisme mesin diubah menjadi tenaga gerak. Fungsi lain dari sistem pendinginan cooling system antara lain Menjaga clearance antar logam agar tidak menyebabkan kemacetan dan kerusakan. Kemacetan teri adi akibat pemuaian logam yang berlebihan. Mengoptimalkan tenaga mesin dan meminimalkan emisi gas buang. Mempercepat mesin mencapai suhu kerja. Pada saat mesin dingin, proses pembakaran tidak sempurna sehingga tenaga yang dihasilkan juga tidak maksimal dan banyak mengandung emisi gas buang.
