Abstract: China's coal mine vehicle started late，design radiator for coal mine vehicle is different from than for common road vehicle，there are great differences.And theoretical design level needs to be improved.The paper introduces the radiator calculation method of shield carrier explosion proof diesel engine combined with practical experience.According to the actual working condition of the vehicle,the example is used to further explain that the radiator design is reasonable to avoid the radiator is too small,the engine water temperature is too high,the radiator is too big,the engine water temperature is too low.The perfect design of radiator,not only improve efficiency of engine,but also increase its useful life.The trackless rubber tires used in coal mines in China started late.The structure of the explosion-proof diesel radiators on the trackless rubber trucks is completely different from that of the ordinary road vehicles.The design methods are quite different.The current theoretical design level needs to be improved.According to the actual use situation,the design and calculation method of the BF6M1015C explosion-proof diesel engine radiator for the bracket truck is introduced.In order to design the reasonable diesel radiator,according to the actual working conditions of the vehicle,the design of the explosion-proof diesel engine heat dissipation,so that the radiator design is reasonable,to avoid the radiator is too small,the engine water temperature is too high;the radiator is too large,the engine water temperature is too low.The qualified design of the radiator can improve the efficiency of the engine and increase its service life.
