Description
technical field [0001] The invention relates to an explosion-proof engine cooling system, in particular to an explosion-proof diesel engine cooling system. Background technique [0002] The underground working space of the mine is relatively closed, and contains flammable and explosive gases such as methane. During the operation of the engine, the temperature of the internal flowing airflow can be as high as 700 °C, which causes the temperature of the outer surface of the engine to exceed the ignition temperature of many flammable substances. General technical conditions for diesel engines MT990-2006 stipulates that the surface temperature of explosion-proof diesel engines shall not exceed 150 ℃ to avoid explosion caused by excessive surface temperature. [0003] Explosion-proof diesel engines usually use a water jacket structure to control the surface temperature. The cooling water used in the water jacket structure is shared with the engine cooling water. Therefore, when t...
