[0002] The fifth generation of mobile communication technology, referred to as 5G or 5G technology, is the latest generation of cellular mobile communication technology, and is also an extension of 4G (LTE-A, WiMax), 3G (UMTS, LTE) and 2G (GSM) systems. The performance goals of 5G are high data rate, reduced latency, energy saving, reduced cost, increased system capacity and large-scale device connection. The first phase of the 5G specification in Release-15 is to adapt to early commercial deployment. The second phase of Release-16 will be completed in April 2020 and submitted to the International Telecommunication Union (ITU) as a candidate for IMT-2020 technology. The ITUIMT-2020 specification requires speeds of up to 20Gbit / s, which can achieve wide channel bandwidth and large-capacity MIMO.

[0003] The promotion of 5G communication technology depends on the large-scale deployment of 5G base stations. Compared with traditional communication base stations, 5G base station equipment is more sensitive and more significantly affected by external temperature changes, especially in winter in northern my country, when the temperature drops sharply, even causing damage to the internal components of 5G base stations. Therefore, it is necessary to install special heating devices on 5G base stations.

[0004] To this end, the present invention provides a PTC heating component dedicated to a 5G base station, which can well solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to provide a PTC heating component dedicated to a 5G base station to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A PTC heating component dedicated to a 5G base station comprises an outer box body, one side end of the outer box body is connected to an air outlet through a through hole, a shutter is installed in the air outlet, an air intake heating box is installed on the bottom wall of the inner cavity of the outer box body, the air intake end of the air intake heating box is connected to an air intake pipe, one end of the air intake pipe away from the air intake heating box passes through the side wall of the outer box body and is cantilevered on the outside, a secondary heating cylinder is provided in the middle of the inner cavity of the outer box body, the secondary heating cylinder is arranged between the air outlet and the air intake heating box, the secondary heating cylinder is a round tube structure, the secondary heating cylinder is fixedly installed on the inner cavity wall of the outer box body by a fixing rod, and the bottom of the secondary heating cylinder The end is connected with a guide bucket matched with the air intake heating box, and the inner cavity of the secondary heating cylinder is evenly provided with a number of second PTC heating rods. The external air enters the air intake heating box through the air intake pipe, and is heated for the first time in the air intake heating box. The heated air is directly discharged into the inner cavity of the outer box body and enters the secondary heating cylinder under the action of the guide bucket, and then is heated for the second time under the action of the second PTC heating rod, thereby increasing the temperature of the air again. The air after secondary heating finally enters the base station through the air outlet, thereby increasing the temperature of the inner cavity of the base station, ensuring that the internal components are in normal working condition, and ensuring the normal operation of the base station.

[0008] In a further embodiment, the air intake heating box includes a box body, which is a cylindrical structure. The inner cavity of the box body is provided with a partition plate, and the partition plate and the box body cooperate to form a heating channel. The heating channel is a serpentine structure. The air intake end of the heating channel is connected to the air intake pipe, and the air outlet end of the heating channel is connected to the air outlet pipe. A number of first PTC heating rods are evenly arranged in the heating channel. The outside air enters the heating channel through the air intake pipe, flows around the heating channel, and is finally discharged through the air outlet pipe. When the air flows in the heating channel, it is preliminarily heated under the action of the first PTC heating rod. The preliminarily heated air enters the inner cavity of the outer box body through the air outlet pipe for further heating treatment. The air is effectively preheated by the first PTC heating rod, and the temperature of the air can be effectively and quickly increased, thereby ensuring that the temperature in the base station can maintain the normal operation of the components.

[0009] In a further embodiment, the structures of the first PTC heating rod and the second PTC heating rod are exactly the same, and a number of teeth are evenly arranged on the first PTC heating rod, and the spacing between adjacent teeth is 3.5 mm, thereby improving the stability of the first PTC heating rod, increasing the heating speed, and ensuring the heating quality of the air, and the surfaces of the first and second PTC heating rods are provided with a thermal insulation coating.

[0010] In a further embodiment, the bottom wall of the inner cavity of the air intake pipe is inclined and the lowest end is cantilevered on the outside. The inner cavity of the air intake pipe is provided with an air intake fan, a water filter layer, a dust filter net and a protective net from the inside to the outside. The air intake fan is fixedly installed on the inner hole wall of the air intake pipe through a connecting rod. Through the action of the air intake fan, the outside air is drawn into the air intake pipe, and finally enters the air intake heating box through the air intake pipe for preliminary heating. When the air is in the air intake pipe, the floating dust particles in the air are filtered out by the dust filter net, and the moisture in the air is filtered out by the water filter layer, thereby improving the quality of the air, preventing floating dust impurities in the air from entering the base station, affecting the normal operation of the components, and ensuring the service life of the base station.

[0011] In a further embodiment, a mounting plate is provided on the side of the outer box body away from the air outlet, and the mounting plate is fixedly mounted on the outer box body by a mounting rod. A number of threaded holes are evenly arranged on the mounting plate, and the mounting plate can be installed in the inner cavity of the base station by means of the threaded holes and bolts, thereby fixing the entire device in the inner cavity of the base station, thereby ensuring the operating stability of the entire device.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. When the present invention is used, the external air enters the air intake heating box through the air intake pipe, and is heated for the first time in the air intake heating box. The heated air is directly discharged into the inner cavity of the outer box body and enters the secondary heating cylinder under the action of the guide bucket, and then is heated for the second time under the action of the second PTC heating rod, thereby increasing the temperature of the air again. The air after the secondary heating finally enters the base station through the air outlet, increasing the temperature of the inner cavity of the base station, ensuring that the internal components are in normal working condition, and ensuring the normal operation of the base station;

[0014] 2. When the present invention is used, the outside air enters the heating channel through the air inlet pipe, flows around the heating channel, and is finally discharged through the air outlet pipe. When the air flows in the heating channel, it is preliminarily heated under the action of the first PTC heating rod. The preliminarily heated air enters the inner cavity of the outer box through the air outlet pipe for further heating treatment. The first PTC heating rod effectively preheats the air, which can effectively and quickly increase the temperature of the air, thereby ensuring that the temperature in the base station can maintain the normal operation of the components;

[0015] 3. The present invention uses the suction fan to draw the outside air into the air intake pipe, and finally enters the air intake heating box through the air intake pipe for preliminary heating. When the air is in the air intake pipe, the dust particles in the air are filtered out by the dust filter net, and the moisture in the air is filtered out by the water filter layer, thereby improving the air quality, preventing the dust impurities in the air from entering the base station and affecting the normal operation of the components, thereby ensuring the service life of the base station.
