NOVELTY - The utility model model claims a radiator for diesel locomotive, comprising a top cover, a main body and a bottom plate, the centre of the inner part of the top cover is provided with a trapezoidal groove, the middle part of the trapezoidal groove is provided with multiple radiating holes, two sides of the outer wall of the main body are provided with multiple ventilation holes, the inner part of the main body passes through the cooling fixedly connected with, the inner respectively of the first mounting groove and the second mounting groove is provided with a filter screen and a radiating grid, the inner part of the locating block is provided with a clamping groove, the clamping groove is provided with a heat conducting sheet. The utility model model is composed of a radiating grid, the filter screen and the heat conducting sheet are matched with each other, by using the bottom plate composed of graphene filter screen and radiating grid, then combined with the heat conducting sheet of the top part, it can effectively conduct the heat generated by the internal combustion locomotive from the bottom of the radiator, after cooling by the cooling pipe, it reaches better radiating effect, and the filter screen can greatly reduce the floating dust entering the radiator from the bottom, reducing the accumulation of dust in the radiator.
