Internal heat dissipation design of power distribution cabinet
Jan 08, 2022
Our distribution ark inside have to deposit a large amount of power or communications equipment, but these devices work in for a long period of time will inevitably be in the process of power distribution cabinet internal temperature, power distribution cabinet internal high temperature to work properly, will seriously affect the equipment delay our normal work schedule, so our distribution of heat dissipation problems cannot be ignored, and the need to pay more attention to, the following us Let's see how to solve the three-person problem inside the power distribution cabinet. For example, the outdoor stainless steel cabinet for communication system refers to the cabinet made of metal or nonmetal under the direct influence of climate, which does not allow operators to enter the operation and is suitable for communication equipment to be installed outdoors.
1. Ventilated, the air outside the shell is convection with the air inside the equipment cabin of the chassis cabinet. No ventilation, the air outside the shell is not convection with the air inside the equipment cabin of the chassis cabinet.
2. Heat insulation type, chassis The cabinet shell is a multi-layer structure consisting of low thermal conductivity sandwich material. Low voltage distribution phase air conditioning, no convection between the air outside the cabinet and the air inside the cabinet equipment cabin structure, the temperature of the machine is controlled and adjusted by air conditioners.
3. Heat exchange type, the air outside the cabinet does not convection with the air inside the equipment cabin of the cabinet, and the temperature inside the machine is controlled and adjusted by heat exchanger.
4. Fan type: the air outside the cabinet is convection with the air inside the equipment compartment of the cabinet, and the forced convection of the fan is used for heat transfer.
5. Natural ventilation: the air outside the cabinet is convection structured with the air inside the equipment cabin of the cabinet, and the natural wind is used to transfer heat to the equipment inside the cabinet.
