In remote areas with weaker signals, the CPE equipment can realize stable signal connection through a signal transmitting device with higher power and more antennas, and provide a stable network for equipment such as monitoring cameras. Because the network is provided for the arranged monitoring cameras by using CPE without expensive cost for paving communication lines, the monitoring is arranged in the border zone near each port of the border area and with higher risk of stealing, then the anti-theft and anti-smuggling by using CPE networking is a common means for guaranteeing the security of border protection and carrying out the anti-smuggling work, the China is wide in the area of territory, the border lines cover various climates from tropical rain forests to plateau snow mountain, and the video monitoring is carried out by using CPE networking, so that CPE equipment is required to have stable high-performance whether in damp and hot rain forests or in the plateau snow mountain with tens of degrees below zero. Currently, existing outdoor CPE devices typically use metal or engineering plastic for the housing and integral heat sinks for heat dissipation. However, when using the outdoor CPE device described above, there are often the following technical problems: Because the heat conductivity and the thickness of shell are certain, when current outdoor CPE equipment dispels the heat outwards, the thermal resistance is invariable, can't adjust the thermal resistance that dispels the heat outwards according to ambient temperature change, this leads to current equipment to give attention to the radiating effect when high temperature and the heat preservation effect when low temperature, and the design of whole fin can accelerate the heat loss in equipment simultaneously in low temperature environment, leads to equipment performance reduction in low temperature environment, consequently current outdoor CPE equipment can't all have stable high performance in high temperature and low temperature environment.
