谷物联合收获机传统的冷却方式是由发动机曲轴以定传动比形式驱动冷却风扇和水泵运转的，这种冷却方式经常出现低速大负荷时冷却不足、高速小负荷时冷却过度等问题。

The driven force of fan and pump in the traditional way of the cooling system in cereal combining harvesters comes from crankshaft of the engine by decided transmission ratio.

强制冷却：将高温钢材强制冷却到设计温度的工序，可防止钢材硬化过度，破裂或者内部损伤。

CONTROLLED COOLING: Process by which steel is cooled from an elevated temperature in a predetermined manner to avoid excessive hardening, cracking or internal damage.

这是我们的蓄电池，那已经氮过度增压，面临着在核心里压力的损失，那会自动的加入冷却剂到，核心去，然后就会产生一个破裂。

Here is our accumulator which has that nitrogen overpressure which upon loss of pressure in the core would automatically insert coolant into the core should there be a break.
