What causes the electrical cabinet of CNC machine tools to heat up?
- The heat generated by the components installed inside the #machine #center #electric #cabinet will increase the temperature inside the electric cabinet. Since heat can be dissipated through the surface of the electric cabinet itself, the internal temperature of the electric cabinet and the external temperature will be balanced at a certain hot water level. If the heat generated is a constant, the larger the surface area of the electric cabinet, the slower the temperature rise inside the electric cabinet.
- The temperature rise design of the electric cabinet requires calculation of the #heat #generated in the electric cabinet and estimation of the surface area of the electric cabinet. The internal temperature of the electric cabinet can be improved by installing an #air-conditioner or #heat #exchanger inside the electric cabinet for cooling.
When designing the electric cabinet, it is necessary to ensure that when the temperature inside the electric control box rises, the temperature difference between the inside and outside the box does not exceed 10°C.
- For servo amplifier modules with heat sinks, try to install the heat sink outside the eelectric cabinet, because the heat sink has a great influence on the temperature inside the box. At the same time, to prevent environmental effects, consider adding protection to the heat sink.
- As shown in the FANUC amplifier module outline diagram, the servo amplifier is designed to be installed in the electric control box, and its heat sink passes through the back of the electric control box. This will remove the heat generated by the semiconductors in the amplifier, thereby minimizing the build-up of heat in the electrical control box.
When the electric cabinet is large enough and the heat dissipation of the system unit in the electric cabinet is less than the surface area of the electric cabinet, no special treatment is needed.
The purpose of heat dissipation can be achieved through the surface of the electric cabinet without exceeding the allowable limit. temperature. When the surface area of the electric control box cannot meet the requirements, heat must be dissipated through a air conditioner or heat exchanger. So what's these two type of hardware?
