1, ventilation: the structure of the convection between the outer air of the shell and the air in the cabinet of the cabinet.

2, no ventilation: the structure of the air in the outer shell of the shell and the air in the cabinet of the cabinet.

3, heat insulation: cabinet cabinet shell is a multi-layer structure with low heat conduction sandwich material.

4, air conditioning type: the air in the cabinet and the air of the cabinet are not convective in the cabin. The temperature in the machine is controlled by the air conditioner. Distribution cabinet distribution cabinet

5, heat exchange type: the air of the cabinet outside and the inner air of the cabinet equipment cabin do not carry out the convection structure, and the temperature in the machine is controlled and adjusted by the heat exchanger.

6, fan type: the outer air of the cabinet and the inner air of the cabinet equipment cabin are convective structure, and the heat transfer mode is forced by the fan to force the convection.

7, natural ventilation: the exterior air of the cabinet and the inner air of the cabinet equipment cabin are convective structure, and the heat transfer mode is carried out by natural wind to the equipment in the cabinet.
