Description

Technical Field

[0001] The invention relates to the technical field of heat dissipation of communication base stations, and in particular to an energy-saving heat exchange radiator of a communication base station. Background Art

[0002] As the telecommunications industry's telecommunications rooms and communication base stations enter the communication cabinets of the 5G era, the power consumption of electronic components in the cabinets has increased dramatically. Under the premise that the electronic components in the cabinets are in a stable operating state, one of the important prerequisites is that the thermal control of the internal and external environments of the cabinets reaches a stable state; therefore, the reliability of the temperature control system of the cavity space in the cabinet and the intelligence of its temperature control process will also greatly affect the enhancement and performance of the communication cabinet functions.

[0003] The existing publication number CN105682426B discloses a heat exchange device suitable for a communication base station cabinet, which includes a heat absorption unit and a heat dissipation unit. The heat is dissipated by heat exchange. When the air flow in the communication cabinet passes through the heat absorption unit, the heat absorption unit transfers the heat to the heat transfer medium and vaporizes it. The vaporized heat transfer medium enters the heat dissipation unit through the gaseous medium channel pipe. When the external cold air takes away the heat in the heat dissipation unit, the heat transfer medium is liquefied and refluxed under the action of gravity. This reciprocating cycle has high heat exchange efficiency, more efficient heat dissipation, more energy-saving and reliable, and significant temperature control effect, which is conducive to ensuring the stable operation of communication equipment and avoiding various faults and hidden dangers caused by unstable heat management of the communication base station cabinet.

[0004] Although the existing technology has achieved heat dissipation for communication base stations to a certain extent, the existing technology uses multiple cooling fans to heat the communication base stations, which increases the power consumption to a certain extent.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. A top heat dissipation hole is opened on the top of the base station shell. A top plate is arranged on the top of the base station shell. An air circulation channel is formed between the top plate and the base shell. Due to the difference in density, the hotter air inside the cabinet will flow upward, thereby taking the heat inside the cabinet out from the top heat dissipation hole. Due to the action of external wind force, the air itself is flowing, and the flowing air further takes away the air on the top of the cabinet, increasing the air flow inside the cabinet, achieving good heat dissipation, and not consuming electrical energy, which is more energy-saving.

[0018] 2. The second heat dissipation mechanism includes a heat dissipation component located in the base shell and a fan blade mechanism that drives the heat dissipation component. The fan blade mechanism can drive the heat dissipation component to work, thereby increasing the air flow without consuming electrical energy. The rotation of the fan blade component can drive the second blade component to rotate, thereby discharging the hot air inside the base station shell, increasing air flow, and achieving heat dissipation. The blade edge of the second blade component is provided with a plurality of grooves, which are used to change the flow path of the airflow, reduce the eddy current intensity, and thus reduce the noise level. The grooves allow more airflow to flow along the blade surface to a certain extent, rather than directly detaching, which helps to improve the suction capacity of the fan.

[0019] 3. The fan blade assembly includes a shaft, inner blades, connecting rods and outer blades. The shaft is equipped with inner blades, and multiple outer blades are evenly installed on the shaft through connecting rods. The cooperation of the inner blades and the outer blades improves the utilization effect of wind force, so that the fan blade assembly can rotate well, and then achieve good driving of the second blade assembly; the inner blades, connecting rods and outer blades are all made of lightweight materials, and the lightweight materials reduce the dependence on wind force level to a certain extent; the surface of the inner blade is a mirror structure, and the mirror structure can reflect light and have a certain degree of bird-repelling effect, preventing birds from nesting at the base station to a certain extent, thereby eliminating the need for workers to climb high to clean the bird nests.

[0020] 4. The opening directions of the two unit blades are opposite. The two arc-shaped blades with opposite opening directions improve the utilization effect of wind force, so that the fan blade assembly can rotate well, and then achieve good driving of the second blade assembly.

[0021] 5. The first heat dissipation mechanism includes a heat dissipation fan, a water-cooled heat dissipation component and a heat dissipation fin component. A heat dissipation fan is installed on one side of the heat dissipation fin component, and the heat dissipation fin component passes through the water-cooled heat dissipation component. Through the cooperation of the heat dissipation fan, the water-cooled heat dissipation component and the heat dissipation fin component, a good heat exchange function can be achieved, and the heat inside the base station shell can be brought out well.
