A lot of power or communication equipment is stored inside our power distribution cabinet, but the temperature inside the power distribution cabinet will inevitably rise during these long-term work. The high temperature inside the power distribution cabinet will seriously affect the equipment. It works normally and delays the normal work schedule, so the heat dissipation problem of our power distribution cabinet cannot be ignored and needs to be taken seriously.

For example, outdoor stainless steel cabinets and cabinets used in communication systems refer to cabinets that are directly outdoors and are made of metal or non-metal under the influence of various weathers. They are not allowed to enter the operation and are suitable for outdoor installation of communication equipment.

1. Ventilation, the structure of convection between the air outside the shell and the air inside the equipment compartment of the cabinet cabinet.
2. There is no ventilation type, and there is no convection between the air outside the shell and the air in the equipment compartment of the cabinet cabinet.
3. Insulation type, the cabinet cabinet shell is a cabinet with multi-layer structure containing low thermal conductivity interlayer material. Low-voltage distribution cabinet.
4. Air-conditioning type. There is no convection between the air outside the cabinet and the air in the equipment compartment of the cabinet. The temperature inside the machine is controlled and regulated by an air conditioner.
5. Heat exchange type, the structure of the air outside the cabinet and the air inside the equipment compartment of the cabinet does not have convection, and the temperature inside the machine is controlled by a heat exchanger.
6. Fan type, a structure in which the air outside the cabinet is convected with the air inside the equipment compartment of the cabinet, and the fan uses forced convection for heat exchange.
7. Natural ventilation type, the convection structure between the air outside the cabinet and the air inside the equipment compartment of the cabinet, and the method of using natural wind to exchange heat between the equipment in the cabinet.
