仿威图机柜上的散热孔主要出现在机柜上，由于机柜内部的电子零件、设备运行时会产生热量，为了保障机柜内部有一个稳定、适宜温度的运行环境，大部分机柜都需要配备散热冷却系统以及在机柜上设计排除热量的散热孔。
The cooling holes on the imitation Rittal cabinet mainly appear on the cabinet. Because the electronic parts and equipment inside the cabinet will generate heat during operation, in order to ensure a stable and suitable temperature operating environment inside the cabinet, most cabinets need to be equipped with a cooling system and cooling holes designed on the cabinet to remove heat.
为保证设备不受外界的电磁干扰，通常对设备外部加上金属屏蔽机箱，而由于需要散热、通风等因素的存在，不可避免的需要在机箱上开孔开缝。
In order to ensure that the equipment is not subject to external electromagnetic interference, a metal shielding case is usually added to the outside of the equipment. However, due to the need for heat dissipation, ventilation and other factors, it is inevitable to open holes and seams on the case.
但外部的电磁干扰信号通过这些孔缝进入机箱内部，就会影响机箱正常工作。因此为了确保机柜外壳的屏蔽效能，研究、设计人员就需要对散热孔孔的形状、长宽比以及入射波极化方向等参数进行合理设置，那么这也会加大了对机柜外壳的加工难度。
However, the external electromagnetic interference signal enters the chassis through these holes, which will affect the normal operation of the chassis. Therefore, in order to ensure the shielding effectiveness of the cabinet shell, researchers and designers need to reasonably set the parameters such as the shape of the cooling hole, the aspect ratio and the polarization direction of the incident wave, which will also increase the processing difficulty of the cabinet shell.
散热孔加工工艺主要看机柜的形状设计以及应用范围，比如家用电脑使用环境比较稳定，散热孔都是平面的，那么通过激光切割的方式就可以直接加工。
The processing technology of the cooling hole mainly depends on the shape design and application range of the cabinet. For example, the use environment of the home computer is relatively stable, and the cooling hole is flat, so it can be directly processed by laser cutting.
但是像户外环境所使用的机柜，散热孔不仅要排出机柜内部热量，同时也对防雨性能有一定要求，因此为了避免雨水、灰尘的渗入，散热孔设计是有一定角度要求的，这时就只能通过模具冲压加工成型的方式来完成。
But like the cabinet used in outdoor environment, the cooling hole not only needs to discharge the heat inside the cabinet, but also has certain requirements for rain-proof performance. Therefore, in order to avoid the infiltration of rain and dust, the design of the cooling hole is required from a certain angle. At this time, it can only be completed by die stamping and processing.
That's all about the processing of the cooling hole on the imitation Rittal cabinet. If you have any doubts or questions about it, please come to our website at any time http://www.tongyuhengcheng.com Get to know!
