Description

An optical cable transfer box with a cooling device

technical field

The invention relates to an optical cable transfer box, in particular to an optical cable transfer box with a cooling device.

Background technique

With the continuous development of social informatization, optical fiber is more and more widely used in communication, and the application of optical cable transfer boxes is becoming more and more extensive. Generally, optical cable transfer boxes are placed outdoors for use. The optical cable transfer box has no ventilation equipment. If the external temperature is high, the optical network unit (ONU) placed in the optical cable transfer box will crash due to excessive temperature, especially when the temperature is high in summer and the sun directly shines on the optical cable. When the transfer box is installed, the temperature in the cable transfer box will reach 60°C, and the ONU itself emits a lot of heat when it is working. The heat in the box cannot be removed, which will easily cause the ONU to crash, affect normal work, and reduce work efficiency.
