Product function

The function of the Water Jacket is to transfer the temperature of the engine combustion chamber and the inner wall of the cylinder to the coolant through heat conduction. Because the liquid is flowable, it circulates through the water pump to the radiator. The radiator heats the coolant through the flow of outside air, and then Dissipate the superheated coolant and circulate to the engine water jacket to receive the heat generated by the engine during operation, and so on. The summary is to transfer heat.
The Water Jacket in a car engine is actually a porous water pipe. When the cooling water circulating from the water tank reaches the engine, if there is only one water outlet, the cooling effect will be relatively concentrated. The effect is better at a place close to the water outlet, and of course the effect is worse at a far place. In the long run, It is very detrimental to the average service life of the engine. Therefore, a porous water outlet pipe is designed to allow cold water to flow out of multiple holes, so that the cooling effect of the entire engine is relatively balanced, so as to extend the service life of the engine. Water Jacket is widely used in larger engines, and there are many small engines that do not use Water Jacket.
