The cooling system is the key to maintaining the normal operation of all large and heavy locomotive engines. The heat dissipation network system is usually located behind the front wheels. Once it is hit by a large stone or foreign object during driving, the heat dissipation network of the water tank will be broken or damaged. Damage, seriously affecting the heat dissipation and operation of the engine,DIMOTIV designed a series of protection nets for the different water cooling and oil cooling systems of various commercially available cars. The outer frame is made of all aluminum alloy, and the mesh surface is made of aluminum alloy. The mesh surface is large. The hole design does not affect the original heat dissipation function. The contact position on the back of the water tank is equipped with thermal insulation sponge, which can completely improve the situation of the water tank frame caused by vibration of the commercial water tank net, effectively protect the water tank and avoid damage to the water tank. In addition, the DIMOTIV water tank protection net is different from the general commercial water tank protection net, the aluminum alloy net surface achieves protection and beauty, and enhances the personal knight style
