They are generally two different types of cooling system:water-cooling system and air-cooling system.Water-cooling system is more common.The cooling medium, or coolant, in them is either water or some low-freezing liquid, called antifreeze.A water-cooling system consists of the engine water jacket, thermostat, water pump, radiator, radiator cap, fan, fan drive belt and neccessary hoses.
A water-cooling system means that water is used as a cooling agent to circulate through the engine to absorb the heat and carry it to the radiator for disposal.The ebgine is cooled mainly through heat transfer and heat dissipation.The heat generated by the mixture burned in the engine must be transferred from the iron or aluminum cylinder to the waterin the water jacket.The outside of the water jacket dissipates some of the heat to the air surrounding it, but most of the heat is carried by the cooling water to the radiator for dissipation.When the coolant temperature in the system reaches 90',the termostat valve open fully, its slanted edge shutting off the sforter circuit so that coolant circulates through the longer one: water-pump-cooling jacket-thermostat-radiator top-tank-radiator core-bottom tank-pump.
Water pumps have many designs, but most are the centrifugal type.They consist of a rotating fan,or impeller,and seldom are of the positive displacement type that uses gears or plungers.Many water pumps have a spring-loaded seal to avoid leakage of water around the pump shaft.Some V-type engines have a pump on each cylinder biock.
The radiator is a device designed to dissipate the heat which the coolant has absorbed from the engine;it is constructed to hold a large amount of water in tubes or other passages which provide a large area in contact with the atmosphere.
The radiator usually mainly consists of the radiator core, radiator bottom tank,and radiator top tank.Radiator cores are of two basic types,the fin and tube(fins are placed around the tubes to increase the area for radiating the heat)and of the ribbon cellular or honey comb tybe.The popular fin and tube type of radiator core has the advantage of fewer soldered joints and is there a stronger construction.It consists of a series of pareller tubes extending from the upper to the lower tank.The honeycomb type core consists of a large number of narrow water passage made by soldering pairs of thin metal ribbons together their edges.These tubes are separated by fins of metal ribbon which help dissipate the heat.
The radiator cap serves not only to prevent the coolant from splashing out the filler opening,but also to prevevt evaporation of the coolant.
The fan designed to draw cooling air through the radiator core.The fan is usually mounted on an extension of the water pump shaft and is driven by V-belt from a pulley mounted on the front end of the crabkshaft.Usually the same belt drives the alternator, and belt tension is adjusted by swinging the alternator on its mounting.

他们通常是二个不同的类型冷却系统:水-冷却系统和空气-冷却系统。水-冷却系统是更通常的。冷却的媒体 , 或冷冻剂,在他们里面是水或一些低冰冻的液体,叫做防冻剂。一个水-冷却系统由引擎水夹克，自动调温器，水泵，暖器炉，暖器炉无边帽，狂热者，狂热者推进力带子和 neccessary 水管所组成。
一个水-冷却系统意谓水被当作一个冷却的代理人使用流通过引擎为处理吸收热而且将它携带到暖器炉。ebgine 被经过热移动和热放荡主要地冷却。被在引擎中被燃烧的混合产生的热从铁或铝圆筒到 waterin 水夹克一定被转移。那在水夹克的外面使对空气的一些热发泄围住它,但是大部份热为放荡被对暖器炉的冷却水携带。当在系统中的冷冻剂温度到达 90 的时候',termostat 活瓣完全打开, 它的使倾斜边缘关闭 sforter 线路以便冷冻剂流通过一个比较长的: 水-泵- 冷却夹克-自动调温器- 暖器炉顶端-战车- 暖器炉核心- 底部箱-泵。
水泵有许多设计，但是大部分是离心的类型。他们由一个替换狂热者 , 或推进者所组成, 和很少是有积极的换置类型的以使用齿轮或跳进的人。许多水泵有春天装载的印章在泵桥的周围避免水的漏。一些 V- 类型引擎有在每圆筒 biock 上的一个泵。
暖器炉是一个装置设计使冷冻剂从引擎吸收 ; 它是构造举行管或提供大气给一个大的区域在连络中的其他通道的很多水热发泄。
暖器炉通常主要地由暖器炉核心 , 暖器炉底部箱 , 和暖器炉顶端箱所组成。暖器炉核心是有二基本类型的,鳍和管 (鳍被放置在管的周围为放射热增加区域) 而且缎带格状自动化或蜂蜜梳头发 tybe 。暖器炉核心的流行鳍和管类型有较少数的利益施以焊接了关节而且那里一个较强壮的建筑。它由一系列的 pareller 管所组成从上面者到较低的战车扩充。蜂巢的类型核心由在藉由一起焊接瘦的金属双缎带他们的边缘被做的很多狭窄的水通道所组成。这些管被帮助使热发泄的金属制的缎带鳍分开。
暖器炉无边帽服侍对冷冻剂的 prevevt 蒸发不但阻止冷冻剂溅湿出匈牙利货币单位打开 , 而且。
狂热者设计拉冷却晾干制的过暖器炉核心。狂热者通常被装在水泵桥的延长上并且被来自一个被增加在 crabkshaft 的较前面的结束上的滑车 V- 带子驱使。通常相同的带子驾驶交流发电机 , 和紧张藉由摇摆在它的架设上的交流发电机被调整的带子。
