Explosion-proof motors are mainly used in coal mines, oil and natural gas, petrochemical and chemical industries. The explosion-proof type motor uses an explosion-proof enclosure to separate the electrical parts that may generate sparks, electric arcs and dangerous temperatures from the surrounding explosive gas mixture. This requires the explosion-proof enclosure to maintain tightness as much as possible, so as to reduce the risk that the surrounding explosive gas mixture enters the motor through the joint surface gaps of each part of the enclosure and contacts the ignition sources such as sparks, electric arcs and dangerous high temperatures inside the enclosure and explodes;
[0003] However, the heat generated by the operation of the internal motor of the closed explosion-proof enclosure will also accumulate and increase without a place to release, which is likely to cause thermal damage to the motor components.
