The engineering vehicle engine hood comprises a hood body, a plurality of heat dissipation holes penetrating through a top hood are formed in the bottom of a heat dissipation groove, a pair of deformation heat dissipation assemblies are symmetrically arranged on the side wall of the heat dissipation groove, each deformation heat dissipation assembly comprises a hot bending plate, and sawtooth thorns are arranged on the left side wall and the right side wall of each hot bending plate. The hot bending plate is made of memory metal materials, the sawtooth thorns are made of flexible metal materials, the deformation heat dissipation assembly is in an arc shape in a normal-temperature state, the hot bending plate shakes through vibration generated by working of an engine, the sawtooth thorns on the edge of the hot bending plate generate wingtip vibration, so that the flow speed of surrounding air is increased, and the heat dissipation efficiency is effectively improved; when the temperature in the engine hood is too high, the hot bending plate made of memory metal can be bent towards the middle, the two deformation heat dissipation assemblies are folded to form a barrel-shaped structure in cooperation with the electric rotating shaft, and the temperature in the engine hood is rapidly extracted through the chimney effect.

    本发明提供了应用于发动机罩领域的一种工程车发动机罩,包括罩体,散热槽底部开设有多个贯穿顶罩的散热孔,散热槽侧壁对称设置有一对形变散热组件,形变散热组件包括热弯板,热弯板左右侧壁均设置有锯齿刺,热弯板采用记忆金属材料制成,锯齿刺采用柔性金属材料制成,形变散热组件在常温状态下呈弧形,利用发动机工作产生的震动使得热弯板抖动,其边缘的锯齿刺产生翼尖震颤使得周围空气流速加快,有效提高了散热效率,当发动机罩内部的温度过高时,记忆金属制成的热弯板可以向中间弯曲,配合电动转轴实现两片形变散热组件合拢形成筒状结构,利用烟囱效应是的发动机罩内部的温度更快的被抽离。
