水冷却就是利用水作为吸热介质去冷却高温件,然后再将热量传递给外界空气,从而保持发动机在最适宜的温度状态下工作。 水冷却的效果好(水的传热系数为风的24倍,散热系数为风的900倍)、冷却均匀、运转噪声小,但是由于增加了水泵、散热器、风扇、水套等,使得发动机结构更加复杂,重量、成本增加,而且容易出现漏水、冰冻、水垢沉积等故障,也给维修保养增加了困难。60年代,国外水冷却就已经在摩托车发动机上采用,如今已
Water cooling is the use of water as a heat absorbing medium to cool the high temperature, and then pass the heat to the outside air, so as to maintain the engine at the most suitable temperature conditions. Water cooling effect is good (water heat transfer coefficient of 24 times the wind, the cooling coefficient of 900 times the wind), cooling, running noise, but due to an increase of pumps, radiators, fans, water jacket, making the engine The structure is more complicated, the weight and the cost are increased, and faults such as water leakage, freezing and scale deposition are easy to occur, and the maintenance and maintenance are also added to the difficulty. 60 years, foreign water cooling has been used in motorcycles, and now has
