Description

A receiver for wireless communication network that is easy to maintain

technical field

The invention relates to the technical field of network receivers, in particular to a receiver for a wireless communication network that is easy to maintain.

Background technique

During the operation of the receiver, the chipset and circuit board used inside will heat up. If the heat generated by the chipset and the circuit board cannot be dissipated in a timely manner, the resistance of the receiver itself will increase, thereby further increasing the heat generated by the receiver itself, thereby increasing the power consumption of the receiver and degrading its performance. Most of the existing heat dissipation methods for receivers use air cooling for cooling. After a long time of air-cooled work, the dust in the air accumulates on the inner wall of the receiver, which reduces the heat dissipation rate of the air-cooled mode. At the same time, the dust will increase the possibility of static electricity. After the static electricity accumulates, it will break down electronic devices, causing circuit boards and The chipset is damaged and stops working.

In view of the above problems, the existing receiver needs frequent maintenance and cleaning of the receiver. Regularly clean the dust inside the receiver, which increases the frequency of receiver downtime for maintenance. Frequent downtime for cleaning reduces the working time of the receiver and affects the efficiency of use. At the same time, frequent power-off maintenance also reduces the working life of the receiver. What's more, the existing air cooling is often to carry out the same degree of air cooling to all electronic components, so that the amount of cooling received by low-heating electronic components is excessive, resulting in waste of resources and increasing the cost of electronic components. Exposure to dust in the air leads to continuous accumulation of dust, increasing the need for maintenance. There is therefore a need for a receiver for a wireless communication network that is easy to maintain.
