The embodiment of the invention further provides a heat dissipation method, including the steps of:

Generating a flow of air from the air inlet to the air outlet, the air flow flowing through the at least one communication device for dissipating heat from the at least one communication device, wherein

At least one communication device is mounted on a rod body having at least one air inlet and at least one air outlet on the wall of the rod body, the rod body being connected to a device for generating airflow through the communication device, Used for heat dissipation of communication devices.

The embodiment of the invention further provides a heat dissipation method for a communication device, which comprises the following steps:

Installing a fan page inside the rod body;

Installing a wind sheet outside the rod-shaped object, the wind sheet being connected to the fan sheet through a transmission;

The wind page drives the fan page to rotate by the transmission device, and generates airflow from an air inlet of a lower portion of the rod-shaped object to an air outlet of an upper portion of the rod-shaped object, and communicates through a channel inside the rod-shaped object. device.

The method further includes: installing a blowing device at an air inlet of a lower portion of the rod-shaped object, generating an air flow from an air inlet of a lower portion of the rod-shaped object to an air outlet of an upper portion of the rod-shaped object, through a passage inside the rod-shaped object Flow through the communication device.

The embodiment of the invention further provides a heat dissipation method for a communication device, comprising the following steps:

Installing a fan page inside the rod body;

The wind sheet drives the fan page to rotate by the transmission device, generating an air flow from an air inlet of a lower portion of the rod-shaped object to an air outlet of an upper portion of the rod-shaped object, the airflow passing through the interior of the rod-shaped object Channel through the communication device; and / or

Installing a blowing device at an air inlet of a lower portion of the rod-like body to generate an air flow from an air inlet of a lower portion of the rod-shaped object to an air outlet of an upper portion of the rod-shaped object, the airflow passing through the inside of the rod-shaped body Channel through the communication device; and / or

An air blowing device is installed at an air outlet of the upper portion of the rod-shaped object to generate an air flow from an air inlet of a lower portion of the rod-shaped object to an air outlet of an upper portion of the rod-shaped object, the airflow passing through the inside of the rod-shaped object The channel flows through the communication device.

In contrast, communication equipment, such as: RF module, if the natural heat dissipation method is adopted, the tube alone relies on the natural wind to carry away heat through the RF module, because the area of the RF module itself is often insufficient to support heat dissipation, and the structural part of the RF module is required. Increase the heat sink and expand the heat dissipation area. The larger the heat generated by the RF module, the larger the heat sink area required. This type of heat dissipation is less efficient.

At the same time, if the heat dissipation capacity of the equipment at the top of the tower is not enough, a motor-driven fan is also required to force the air-cooled equipment. For example, a combination of a tower station and a wind power tower, the wind turbine generates electricity, and then supplies electrical energy to the equipment, including air cooling, which also requires conversion of electrical energy to mechanical energy. The utilization rate of energy is not high, it is not energy-saving and environmentally friendly, and the cost is also high.

There is also a method of adding a fan inside or outside the RF module, driving the fan to rotate through the power source, increasing the fluidity of the air, and taking away the heat of the RF module. In this way, the rotating parts are less reliable and require rotating parts (such as fans) to be installed where people can easily access and maintain them.

However, in an embodiment of the invention, the flow of air is passed through the communication device, for example: by passing through the RF module to remove heat. If the outer large blades are used, the rods are driven by the wind. The rotation of the fan page in the object can increase the flow velocity of the gas in the rod body, and effectively solve the heat dissipation problem of the RF module in the communication system. The fan page inside the wind-driven rod-like object realizes a passive fan, does not consume electric energy, is clean and pollution-free, and does not increase operating costs. If a wind blower is used, even if the wind is weak, the air blower can be rotated, and the air below is sucked up and the airflow flows through the RF module to remove heat. In the event of an external wind page failure or insufficient wind, a blower device, such as a blower, can also be used as a backup. Embodiments of the present invention provide sufficient airflow for the tower top communication device to dissipate heat through a suitable airflow path. Communication equipment, for example: The installation method between the RF module and the rod-like object is flexible, and can realize various shapes to meet the needs of the environment.

The rod-like body in the above embodiment may be in various forms such as a rod, a tube, a tower, and the like.

The communication device in the above embodiment may be a communication device such as a radio frequency module or a radio frequency remote unit.

In conclusion, the above description is only a preferred embodiment of the present invention and is not intended to limit the scope of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and scope of the present invention are intended to be included within the scope of the present invention.
