PLC控制柜的使用环境温度与元件的使用温度有关,通常应该在5℃～40℃的范围内.另一方面,在非强制冷却的自然冷却的控制柜等中,由于设备及系统的节省空间及小型化,柜本身也小型化了,那么柜内温度与柜外温度比较,由经验可知有时会高出10℃～15℃以上.因此,有必要针对设置的场所及柜内的发热问题,采取以下的对策,为确保柜内的温度不超过单元的使用温度范围,应尽量保留充足的温度余量,使之在有余量的温度范围内使用.

mojuyz.37ix.com.cnmojulbs.37ix.com.cn the other hand, in the natural cooling control cabinet with non-forced cooling, because of the space saving and miniaturization of the equipment and system, the cabinet itself has been miniaturized, so comparing the temperature inside the cabinet with that outside the cabinet, it is known from experience that sometimes the temperature inside the cabinet will be higher than 10 ~15 C. Therefore, it is necessary. In view of the heating problem in the place and cabinet, the following countermeasures are adopted. In order to ensure that the temperature in the cabinet does not exceed the temperature range of the unit, sufficient temperature margin should be retained as far as possible so that it can be used within the temperature range of the margin.
高温自然风冷式(依靠柜上下的百叶窗自然通风) 向柜内安装时,不使用风扇、空调等冷却设备是很好的方法.
It is a good way to install high temperature natural air-cooled type (relying on natural ventilation of shutters above and below the cabinet) into the cabinet without using cooling equipment such as fans and air conditioners.
