Description

Technical Field

[0001] This utility model relates to the field of hybrid mining truck engine technology, specifically, a hybrid mining truck engine cooling device. Background Technology

[0002] Currently, the cooling method for hybrid mining truck engines on the market is usually achieved through the crankshaft fan built into the engine. During the assembly process, it is not easy to align the crankshaft fan with the air shield. When the vehicle is running, due to the large vibration, the position of the air shield changes, which in turn causes the crankshaft fan to break teeth and be damaged.

[0003] In addition, the intercooler and the water diffuser are usually arranged front and rear. Because the heat generated by the intercooler in this arrangement will also affect the heat dissipation effect of the water diffuser, the size of the radiator assembly will be increased in order to meet the engine cooling requirements. Moreover, the crankshaft fan is a mechanical connection and consumes a lot of energy, which is not conducive to the overall vehicle energy saving. Utility Model Content
