The existing equipment heat dissipation method is generally a fan, which achieves the heat dissipation effect by accelerating air circulation. However, the cooling effect of a conventional fan is not ideal, and for an explosive and flammable Class I (no falling objects area) environment, the heat dissipation equipment should also be explosion-proof treated.
