路面冷再生机在炎热的夏季长距离铣削坚固路面时，常常会出现水温高甚至“开锅”现象。由于环境温度较高，单靠发动机水散热器冷却，往往不能满足散热要求。为此我们添加了1套辅助散热装置。

During the hot summer months, the road surface cold recycling machine often experiences high water temperature and even "boiling" when milling solid road surfaces over long distances. Due to the high ambient temperature, relying solely on the engine water radiator for cooling often cannot meet the heat dissipation requirements. We have added one set of auxiliary cooling devices for this purpose.

路面冷再生机与其他工程机械不同的地方在于，其作业时顶推水车同步行进（水车发动机熄火），水车与冷再生机自身的喷洒系统联合工作，给铣刨转子铣削、拌和的骨料添加适量的水。因此，冷再生机有源源不断的凉水供应。

The difference between the road surface cold recycling machine and other construction machinery is that during its operation, the top pushing water wheel moves synchronously (the water wheel engine is turned off), and the water wheel and the cold recycling machine's own spraying system work together to add an appropriate amount of water to the aggregate milled and mixed by the milling rotor. Therefore, the cold regeneration machine has a continuous supply of cold water.

我们利用这一有利条件，添加了1套辅助散热装置，也就是我们常说的水冷器（通常采用油冷器）。考虑到水的腐蚀性比较大，我们就把筒体材料进行了表面处理（或用不锈钢重新制作），这样就可以用水来冷却。其安装方式如附图所示，其水冷器2与发动机水散热器并列安装，这样凉水即从水冷器的外腔不断流过，发动机的热水从水冷器的内腔通过。

We took advantage of this favorable condition and added a set of auxiliary heat dissipation devices, commonly known as water coolers (usually oil coolers). Considering the high corrosiveness of water, we have treated the surface of the cylinder material (or remade it with stainless steel) so that it can be cooled with water. The installation method is shown in the attached figure. The water cooler 2 is installed in parallel with the engine water radiator, so that the cold water continuously flows through the outer chamber of the water cooler, and the hot water of the engine passes through the inner chamber of the water cooler.

为防止发动机出水口压力不足以及水冷器流过的热水少，在发动机出水管5处增加1个节流装置，这样可使发动机出水口压力增大，发动机流出的热大部分水可流到水冷器中进行冷却。

To prevent insufficient pressure at the engine outlet and insufficient hot water flowing through the water cooler, an additional throttling device is added at point 5 of the engine outlet pipe. This can increase the pressure at the engine outlet, allowing most of the hot water flowing out of the engine to flow into the water cooler for cooling.
