The internal pipes of the intercooler in the mixer often contain dirt such as sludge and gum, which not only narrows the air flow channel, but also reduces the cooling heat exchange. Therefore, it is necessary to carry out maintenance and cleaning. Generally, the internal part of intercooler should be cleaned and inspected every year or when the engine is overhauled or the water tank is repaired by welding. The manufacturer of self feeding self feeding concrete mixer explained that due to the high temperature of the exhaust gas from the engine of self feeding concrete mixer, the heat conduction through the supercharger will increase the temperature of the inlet air. Moreover, the air density will increase in the process of being compressed, which will certainly lead to the increase of air temperature, and then affect the charging power of the engine.

搅拌车涡轮增压的发动机为何会比一般发动机具有更大的动力，其间要素之一便是其换气的功率比一般发动机的天然进气更高。当空气进入涡轮增压后其温度会大幅增加，密度也相应变高，而中冷器恰是起到冷却空气的效果，高温空气通过中冷器的冷却，再进入发动机中。假设缺少中冷器而让增压后的高温空气直接进入发动机，则会因空气温度过高致使发动机损坏甚死火的现象。

One of the reasons why the turbocharged engine of mixer has more power than the general engine is that its air exchange power is higher than the general engine's natural intake. When the air enters the turbocharger, its temperature will increase greatly, and its density will also increase correspondingly. The intercooler just plays the role of cooling the air. The high temperature air enters the engine through the intercooler cooling. If there is no intercooler and the pressurized high temperature air enters the engine directly, the engine will be damaged or even die due to the high air temperature.

搅拌车涡轮增压器或者是机械增压器的后边。实习的情况也确实是这么，大多数车子配备的都是位于散热水箱前的中冷器，而且冷却效果确实比一些顶置计划的中冷器好，但是，这会影响吹到散热水箱的气流。

Behind the mixer turbocharger or supercharger. This is also true in the internship. Most of the cars are equipped with intercoolers in front of the radiator tank, and the cooling effect is better than some overhead intercoolers. However, this will affect the air flow to the radiator tank.

自进料混凝土搅拌车涡轮增压器的疑问就在于罗致新鲜空气的进气口与高温的排气之间距离很近，而且吸进来的新鲜空气被紧缩后温度也会增加很多，所以就算是没有排气高温影响的机械增压发动机也需要通过中冷器来冷却进气。空气被紧缩温度会增加，简略的比如便是给轮胎充气的气泵，不相信的朋友可以摸一下正在充气的气泵，就会知道空气紧缩积攒的热量有多么可怕。

The question of the turbocharger of the self feeding concrete mixer is that the distance between the fresh air inlet and the high temperature exhaust is very close, and the temperature of the fresh air absorbed will increase a lot after it is compressed, so even the supercharged engine without the influence of the high temperature exhaust also needs to cool the intake through the intercooler. When the air is compressed, the temperature will increase. For example, the air pump that inflates the tire. If you don't believe it, you can touch the air pump that is inflating, and you will know how terrible the heat accumulated by the air compression is.
