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.

攪拌車渦輪增壓的發動機為何會比一般發動機具有更大的動力，其間要素之一便是其換氣的功率比一般發動機的天然進氣更高。當空氣進入渦輪增壓后其溫度會大幅增加，密度也相應變高，而中冷器恰是起到冷卻空氣的效果，高溫空氣通過中冷器的冷卻，再進入發動機中。假設缺少中冷器而讓增壓后的高溫空氣直接進入發動機，則會因空氣溫度過高致使發動機損壞甚至死火的現象。

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.

攪拌車渦輪增壓器或者是機械增壓器的后邊。實習的情況也確實是這么，大多數車子配備的都是位于散熱水箱前的中冷器，而且冷卻效果確實比一些頂置計劃的中冷器好，但是，這會影響吹到散熱水箱的氣流。

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.

自進料混凝土攪拌車渦輪增壓器的疑問就在于羅致新鮮空氣的進氣口與高溫的排氣之間距離很近，而且吸進來的新鮮空氣被緊縮后溫度也會增加很多，所以就算是沒有排氣高溫影響的機械增壓發動機也需要通過中冷器來冷卻進氣?？諝獗痪o縮溫度會增加，簡略的比如便是給輪胎充氣的氣泵，不相信的朋友可以摸一下正在充氣的氣泵，就會知道空氣緊縮積攢的熱量有多么可怕。

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.
