发动机双回路冷却系统的介绍!

来源:/ 日期:2019-11-05 发布人:admin
  传统的发动机只使用一个恒温器,而且在缸体和缸盖内只有一个冷却回路,冷却剂在两端温度相同。使用两个恒温器的双回路冷却方法(如图1所示)?分别冷却缸体的液环和缸盖的液环。两个回路的冷却剂温度不同。
  The traditional engine only uses one thermostat, and there is only one cooling circuit in the cylinder block and cylinder head. The temperature of the coolant is the same at both ends. Use the double circuit cooling method of two thermostats (as shown in Figure 1)? Respectively cool the liquid ring of the cylinder block and the liquid ring of the cylinder head. The coolant temperature of the two circuits is different.
  由于气缸盖与燃烧室和排气座椅加热严重,冷却温度较低(83?98℃)。因此,较低的气缸盖温度有利于更充分的膨胀,爆燃和更长的排气座椅寿命。缸体的热强度较低,冷却液温度保持在87?102℃(气缸盖4℃以上),不仅有利于气体膨胀,还可减少摩擦和气体热损失。双回路冷却使两者都能保持温度。
  Due to the serious heating of cylinder head, combustion chamber and exhaust seat, the cooling temperature is low (83? 98 ℃). Therefore, a lower cylinder head temperature is conducive to a fuller expansion, deflagration and longer exhaust seat life. The lower thermal strength of the cylinder block and the temperature of the coolant kept at 87? 102 ℃ (cylinder head above 4 ℃) are not only conducive to gas expansion, but also reduce friction and gas heat loss. Dual circuit cooling keeps both at optimum temperature.
  个是双回路冷却系统

  双环冷却系统与传统的单环冷却系统基本相同。主要的区别是每个缸体和缸盖都有一个冷却回路,在冷却剂分配箱内有两个恒温器(如图2所示),在一个回路中控制冷却剂的流动。然而,两个回路中的冷却剂也会通过气缸盖。
  The double ring cooling system is basically the same as the traditional single ring cooling system. The main difference is that each cylinder block and cylinder head has a cooling circuit, and there are two thermostats in the coolant distribution box (as shown in Figure 2), which control the flow of coolant in one circuit. However, the coolant in both circuits also passes through the cylinder head.
  二是双路冷却系统工作
  Two way cooling system works
  双回路冷却系统流量回路。每个缸体和缸盖都有一个冷却回路,两个恒温器安装在冷却剂分配器上,控制回路中的冷却剂流量。然而,两个回路中的冷却剂也会在气缸盖中交叉。
  Two circuit cooling system flow circuit. Each cylinder block and cylinder head has a cooling circuit, and two thermostats are installed on the coolant distributor to control the coolant flow in the circuit. However, the coolant in both circuits also crosses in the cylinder head.
