Abstract
Description
Technical Field
[0001] This application relates to the field of communication equipment technology, and more specifically, to a comprehensive power-saving device for communication base stations. Background Technology
[0002] To achieve power saving, communication base station integrated energy savers typically integrate core modules such as reactive power compensation and intelligent voltage regulation. These modules generate heat due to component losses during operation. If the heat cannot be dissipated in time, it can lead to accelerated component aging, reduced power saving efficiency, and even equipment failure.
[0003] Existing heat dissipation solutions have significant drawbacks: natural heat dissipation relies on environmental ventilation, but outdoor base stations are exposed to high temperatures and direct sunlight in summer, which can easily cause heat accumulation and make it difficult to meet heat dissipation requirements; forced cooling with fans requires additional power consumption, which goes against the original intention of energy conservation, and fans are prone to dust accumulation and jamming after long-term operation, increasing maintenance costs; simple ventilation holes can enhance air convection, but they can easily introduce dust and rainwater, especially in outdoor scenarios, which can easily lead to short circuits in internal circuits, and the layout of the holes lacks specificity, resulting in limited convection efficiency and making it unsuitable for the complex operating environment of base stations. Utility Model Content
[0004] To overcome the above deficiencies, this application provides a comprehensive power-saving device for communication base stations, which aims to improve the problems mentioned in the background art.
[0005] This application provides an integrated power-saving device for a communication base station, including a power-saving device body and a vertical pipe. A heat dissipation cylinder is provided inside the lower end of the vertical pipe, and the power-saving device body is inserted into the heat dissipation cylinder. A heat exchanger is provided inside the vertical pipe, and the heat exchanger is connected to the heat pipes of other equipment in the base station.
[0006] In one specific implementation, a Venturi tube is provided at the upper end of the vertical pipe.
[0007] In the above process, the Venturi tube is located on the outside, which can protect it from rain. When outdoor air circulates, it can also generate negative pressure, which promotes the exhaust of air from the vertical tube.
[0008] In one specific embodiment, the heat sink includes a slot and a cylinder, the energy-saving device body is inserted into the slot, the slot is fixedly connected to the cylinder, a heat sink is provided between the slot and the cylinder, and the cylinder is connected to the vertical pipe.
[0009] In the above implementation process, the cylinder, slot, and heat sink are a single aluminum unit used to conduct heat out of the energy-saving device. Air enters the cylinder, carries away the heat from the heat sink, and enters the vertical pipe. The vertical pipe needs to be more than two meters long to enhance the chimney effect. The lower end of the cylinder is located inside the equipment cabinet, and an air inlet is provided at the bottom of the equipment cabinet to allow fresh air to enter. On the other hand, the lower end of the slot is open so that even if rainwater enters the vertical pipe, the slot can also protect the energy-saving device from rain.
[0010] In one specific implementation, thermally conductive silicone grease is filled between the energy-saving device body and the slot.
[0011] In the above implementation process, thermal grease is used to improve the heat transfer effect between the energy-saving device body and the slot.
[0012] In one specific implementation, a stop is hinged to the slot opening, and the stop abuts against the energy-saving device body.
[0013] In the above implementation process, after inserting the energy-saving device body into the slot, the stop block is moved to the lower end of the energy-saving device body to block it, and the terminal block at the lower end of the energy-saving device body is exposed in the slot for wiring.
[0014] In one specific implementation, both the vertical pipe and the outer wall of the cylinder are wrapped with heat-insulating cotton.
[0015] In the above implementation process, the heat insulation cotton is used to reduce the heat transfer from the vertical pipe and cylinder to the equipment cabinet where the energy-saving device is located, so as to ensure that the heat is dissipated to the outside. In this embodiment, the equipment cabinet is also equipped with devices with large heat generation, such as switching power supply and radio frequency remote unit. These devices are also attached with cold heads, and coolant flows in the cold heads. The coolant transfers heat to the heat exchanger in the vertical pipe to heat the gas in the vertical pipe and generate a chimney effect. It should be noted that introducing the heat of other devices into the vertical pipe helps to improve the chimney effect. The independent heat dissipation of the energy-saving device can also form a chimney effect.
[0016] In one specific implementation, a shock-absorbing base is also included, which is fixedly connected to the cylinder.
[0017] In the above process, the shock-absorbing seat is used to reduce the vibration transmitted to the energy-saving device body.
[0018] In one specific implementation, a flexible hose is provided between the cylinder and the vertical pipe.
[0019] In the above process, the vertical pipe is rigidly installed on the equipment cabinet and the external mounting bracket, which can reduce the vibration of the vertical pipe transmitted to the energy-saving device body.
[0020] Compared with the prior art, the beneficial effects of this application are: the heat-generating equipment in the base station equipment cabinet is transferred to the heat exchanger in the vertical pipe through the coolant, and at the same time the heat generated by the energy-saving device body is transferred to the heat dissipation cylinder. The heat exchanger and heat dissipation cylinder heat the air in the vertical pipe, generating a chimney effect. Fresh air passes through the heat dissipation cylinder and is drawn into the vertical pipe, which accelerates upward movement and is discharged, achieving efficient comprehensive heat dissipation. No moving structure such as a fan is required, and water ingress can also be avoided. Attached Figure Description

[0024] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.
[0025] Please see Figures 1-3 This application provides a comprehensive energy-saving device for communication base stations, including an energy-saving device body 10 and a vertical pipe 20. A heat dissipation cylinder 30 is installed inside the lower end of the vertical pipe 20, and the energy-saving device body 10 is inserted into the heat dissipation cylinder 30. A heat exchanger 40 is installed inside the vertical pipe 20, and the heat exchanger 40 is connected to the heat conduction pipes of other equipment in the base station. The heat-generating equipment in the base station equipment cabinet is transferred to the heat exchanger 40 inside the vertical pipe 20 via coolant. Simultaneously, the heat generated by the energy-saving device body 10 is transferred to the heat dissipation cylinder 30. The heat exchanger 40 and the heat dissipation cylinder 30 heat the air inside the vertical pipe 20, creating a chimney effect. Fresh air passes through the heat dissipation cylinder 30 and is drawn into the vertical pipe 20, accelerating upwards and being discharged, achieving efficient comprehensive heat dissipation without the need for moving structures such as fans, and also preventing water ingress.
[0026] Please see Figures 1-3A venturi tube 50 is installed at the upper end of the vertical pipe 20. The venturi tube 50 is located on the outside, which can protect it from rain. When outdoor air circulates, it can also generate negative pressure to promote the exhaust of air from the vertical pipe 20.
[0027] Please see Figures 1-3 The heat sink 30 includes a slot 31 and a cylinder 32. The energy-saving device body 10 is inserted into the slot 31, and the slot 31 is fixedly connected to the cylinder 32. A heat sink 33 is provided between the slot 31 and the cylinder 32. The cylinder 32 is connected to the vertical pipe 20. The cylinder 32, slot 31, and heat sink 33 are a single aluminum unit used to conduct heat out of the energy-saving device body 10. Air enters the cylinder 32, carries away the heat from the heat sink 33, and enters the vertical pipe 20. The vertical pipe 20 needs to be more than two meters long to enhance the chimney effect. The lower opening of the cylinder 32 is located inside the equipment cabinet, and an air inlet is provided at the bottom of the equipment cabinet to allow fresh air to enter. On the other hand, the lower opening of the slot 31 can also protect the energy-saving device body 10 from rain even if rainwater enters the vertical pipe 20.
[0028] Please see Figures 1-3 Thermal grease is applied between the energy-saving device body 10 and the slot 31. The thermal grease is used to improve the heat transfer between the energy-saving device body 10 and the slot 31.
[0029] Please see Figures 1-3 A stop 34 is hinged to the opening of the slot 31, and the stop 34 abuts against the energy-saving device body 10. After the energy-saving device body 10 is inserted into the slot 31, the stop 34 is moved to the lower end of the energy-saving device body 10 to block it, and the terminal at the lower end of the energy-saving device body 10 is exposed in the slot 31 for wiring.
[0030] Please see Figures 1-3 Both the vertical pipe 20 and the cylindrical tube 32 are wrapped with heat insulation cotton on their outer walls. The heat insulation cotton is used to reduce the heat transfer from the vertical pipe 20 and the cylindrical tube 32 to the equipment cabinet where the energy-saving device body 10 is located, so as to ensure that the heat is dissipated outdoors. In this embodiment, the equipment cabinet is also equipped with devices that generate a lot of heat, such as switching power supply and radio frequency remote unit. These devices are also fitted with cold heads, and coolant flows in the cold heads. The coolant transfers heat to the heat exchanger 40 in the vertical pipe 20 to heat the gas in the vertical pipe 20 and generate a chimney effect. It should be noted that introducing the heat of other devices into the vertical pipe 20 helps to improve the chimney effect. The independent heat dissipation of the energy-saving device body 10 can also form a chimney effect.
[0031] Please see Figures 1-3 It also includes a shock absorber 60, which is fixedly connected to the cylinder 32. The shock absorber 60 is used to reduce the vibration transmitted to the energy-saving device body 10.
[0032] Please see Figures 1-3A flexible hose 70 is provided between the cylinder 32 and the vertical pipe 20. The vertical pipe 20 is rigidly installed on the equipment cabinet and the external mounting bracket, which can reduce the vibration of the vertical pipe 20 transmitted to the energy-saving device body 10.
[0033] The working principle of the integrated energy-saving device for communication base stations is as follows: The equipment cabinet, antenna, and vertical pipe 20 of the base station are all installed on the mounting frame. The heat-generating equipment such as the switching power supply and radio frequency remote unit in the equipment cabinet transfer heat to the heat exchanger 40 in the vertical pipe 20 through the coolant to heat the gas in the vertical pipe 20 and generate a chimney effect. The airflow is replenished from the heat sink 33 at the energy-saving device body 10 and absorbs the heat of the energy-saving device body 10. Together, they are accelerated out of the vertical pipe 20. The venturi tube 50 is located on the outside and can be rainproof. When the outdoor air is circulating, it can also generate negative pressure to promote the exhaust of air in the vertical pipe 20. The energy-saving device body 10 and the heat sink 30 are connected by a plug-in method, which makes it easy to install and remove the energy-saving device body 10.
[0034] In summary, the heat-generating equipment inside the base station equipment cabinet is transferred to the heat exchanger 40 inside the vertical pipe 20 via the coolant. At the same time, the heat generated by the energy-saving device body 10 is transferred to the heat dissipation cylinder 30. The heat exchanger 40 and the heat dissipation cylinder 30 heat the air inside the vertical pipe 20, creating a chimney effect. Fresh air passes through the heat dissipation cylinder 30 and is drawn into the vertical pipe 20, which accelerates upward movement and is then discharged, achieving efficient comprehensive heat dissipation without the need for moving structures such as fans, and also preventing water ingress.
