The invention discloses an automobile engine cover, which relates to the technical field of automobiles. The automobile engine cover comprises an engine cover outer plate, a reinforced cooling layer is arranged at the bottom of the inner side of the engine cover outer plate, a noise reduction layer matched with the engine cover outer plate is arranged at the bottom of the reinforced cooling layer,and a heat dissipation waterway is arranged in the reinforced cooling layer. Heat of the engine cover is transferred through the heat dissipation water path in the reinforced cooling layer; when passing through the internal waterway, the heat of the high-heat area at the top of the engine exchanges heat with the air inlet and the low-temperature area in the peripheral area, so that the overall heat is equally divided and local high heat is avoided;, and when the windshield is cleaned, water flow in the heat dissipation waterway flows, so that the heat dissipation capacity can be better provided; and the noise of the engine is directly absorbed and reduced through the noise reduction layer, the trace noise obtained after noise reduction is transmitted to the reinforced cooling layer for secondary noise reduction and finally transmitted to the engine cover outer plate, so that the noise transmitted into a cab along the engine cover outer plate is greatly reduced.

    本发明公开了一种汽车发动机盖,涉及汽车技术领域,包括发动机盖外板,所述发动机盖外板内侧底部设置有加固降温层,且加固降温层底部设置有与发动机盖外板配合的消音层,所述加固降温层内部设置有散热水路。本发明通过加固降温层内部的散热水路对发动机盖的热量进行传递,通过内部的水路时发动机顶部高热区的热量与进风口及外围区域的低温区进行热交换,从而使整体热量均分,避免局部高热,当清洗挡风玻璃时,散热水路内部的水流流动,可以更好的提供散热能力;且通过消音层对发动机噪音进行直接吸收降噪,降噪后的微量噪音再传递至加固降温层进行二次降噪,最后再传递至发动机盖外板,从而极大地减少了沿发动机盖外板传递至驾驶室内的噪音。
