The traditional steel plate sheet metal spray paint shell has a built-in heat sink. The heat sink is closed or semi-closed, and the heat dissipation efficiency is low. It is necessary to increase the volume of the heat sink, which wastes materials and increases the weight of the product. In addition, the appearance of the spray paint effect is average and the product grade is low. Therefore, the traditional structure can no longer meet the heat dissipation requirements.

During the installation process, multiple sets of bolts are required for rotating and punching connections, which is complicated to operate and increases the labor intensity of the operators. In this regard, this solution specifically proposes a heat dissipation casing to solve the above problems. Utility Model Content
