Description

Technical Field

[0001] This utility model relates to the field of mobile base station technology, and in particular to a mobile base station heat dissipation duct and liquid cooling synergistic cooling device. Background Technology

[0002] Mobile communication base stations are a core component of wireless communication networks, responsible for transmitting and exchanging wireless signals between mobile terminal devices and the core network. Communication base stations cover specific areas with antennas to provide communication services to users. It is inevitable that communication base station equipment will generate heat during operation. This is because base station equipment, such as radio frequency units, baseband processing units, and power modules, consume a large amount of electrical energy during operation, some of which is dissipated as heat. Additionally, to meet coverage and signal quality requirements, base stations typically transmit signals at high power, and high-power devices such as radio frequency amplifiers generate significant heat during operation.

[0003] Mobile communication base stations need to operate in a relatively constant temperature environment, therefore the cabinets must be equipped with heat dissipation devices. Existing heat dissipation methods include using heat sinks and heat pipes. Heat sinks increase the heat dissipation area, and heat pipes efficiently transfer heat through phase change. Alternatively, ventilation structures can be used to improve airflow efficiency within the cabinet and enhance natural convection cooling. These methods are low-cost but have poor cooling performance. Forced cooling methods also exist, using air conditioning units, semiconductor refrigeration, etc., to cool the inside of the cabinet. These methods have high cooling efficiency but consume a lot of power and are expensive. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a mobile base station heat dissipation duct and liquid cooling synergistic cooling device, which solves the problem of low heat dissipation efficiency in existing communication base station heat dissipation methods.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A mobile base station heat dissipation duct and liquid cooling synergistic cooling device includes a heat dissipation cabinet, inside which a communication control cabinet is installed; an air inlet component is provided at the bottom of the heat dissipation cabinet; two sets of air outlet components are respectively installed on both sides of the heat dissipation cabinet; and a circulating cooling component is provided on the air outlet component.

[0007] In this solution, when the mobile base station is working, air enters the heat dissipation cabinet through the air intake component and then flows out through the air outlet component, carrying away the heat generated inside the cabinet along the way. As the air flows out of the air outlet component, it cools the circulating cooling component and carries away the heat of the coolant inside the circulating cooling component. The coolant continues to circulate inside the circulating cooling component to cool the communication control cabinet. This design utilizes airflow to accelerate the dissipation of heat from the coolant, achieving a synergistic effect of airflow heat dissipation and coolant heat dissipation, resulting in better heat dissipation and lower cost.

[0008] Furthermore, the air outlet assembly includes a fan frame, which is installed inside the heat dissipation cabinet; three exhaust fans are installed in the three mounting cavities in the middle of the fan frame, and three air outlet holes are opened on the side wall of the heat dissipation cabinet at positions corresponding to the three exhaust fans.

[0009] In this solution, the exhaust fan operates, driving the air inside the heat dissipation cabinet to be exhausted through the exhaust vents, thus controlling the dissipation of heat inside the cabinet.

[0010] Furthermore, the circulating cooling component includes a heat-absorbing copper tube and a heat-dissipating copper tube. One end of the heat-absorbing copper tube is connected to one end of the heat-dissipating copper tube; the other end of the heat-dissipating copper tube is connected to the liquid inlet of the circulating pump, and the other end of the heat-absorbing copper tube is connected to the liquid outlet of the circulating pump. The heat-absorbing copper tube is installed on the side of the communication control cabinet, and the heat-dissipating copper tube is installed at the air inlet position of the three exhaust fans through three sets of limiting components.

[0011] In this solution, a circulating pump drives the coolant to circulate between the heat-absorbing copper pipe and the heat-dissipating copper pipe. When flowing through the heat-absorbing copper pipe, the coolant absorbs the heat generated by the communication control cabinet, and when flowing through the heat-dissipating copper pipe, it dissipates the heat. Furthermore, the heat-dissipating copper pipe is located at the air inlet of the exhaust fan, which further accelerates the heat dissipation on the heat-dissipating copper pipe and improves the heat dissipation efficiency when the airflow passes through it.

[0012] Furthermore, the limiting assembly includes a limiting ring, which is fixed around the mounting cavity of the fan frame by screws; the heat dissipation copper pipe is arranged radially through the through holes on the sidewalls of the three limiting rings in sequence; the outer side of the limiting ring is tapped with external threads, and a pressure ring is threaded onto the external threads of the limiting ring.

[0013] Furthermore, the heat dissipation copper pipe is spirally bent in the middle of the limiting ring.

[0014] In this design, the heat dissipation copper pipes are spirally bent, resulting in a large heat dissipation area. At the same time, the heat exchange area with the airflow is also large, which can dissipate the heat carried by the coolant inside the heat dissipation copper pipes more quickly.

[0015] Furthermore, two flexible lugs are connected to each side of the fan frame. The ends of the two flexible lugs pass through the strip holes on the side wall of the heat dissipation cabinet and are snapped into the edge of the strip holes.

[0016] In this solution, when installing the fan frame, the two elastic mounting ears are directly inserted into the slots on the side wall of the cooling cabinet. Under the action of elasticity, the elastic mounting ears are secured in the slots, making installation simple and convenient.

[0017] Furthermore, each air outlet is equipped with a dust cover.

[0018] Furthermore, the air intake assembly includes an air filter, which is installed in the air intake holes on both sides of the heat dissipation cabinet.

[0019] In this solution, the air filter screen filters the air entering the heat dissipation cabinet to prevent dust and debris from being blown into the cabinet.

[0020] Furthermore, an electrical mounting bracket is installed inside the heat dissipation cabinet, and the electrical mounting bracket is located below the communication control cabinet.

[0021] In this design, air enters through the air inlet, passes through the electrical appliance mounting bracket, and is then blown out by the exhaust fan. During the airflow, the electrical equipment mounted on the mounting bracket is cooled.

[0022] Furthermore, the front of the heat dissipation cabinet has two movable doors; each door is equipped with an observation window.

[0023] The beneficial effects of this utility model are:

[0024] In the mobile base station heat dissipation duct and liquid cooling synergistic cooling device provided by this utility model, airflow enters from the air inlet of the heat dissipation cabinet during heat dissipation, and is then blown out from the air outlet by the action of the exhaust fan, carrying away the heat generated inside the cabinet along the way. A circulating cooling component is set up, in which the coolant circulates between the heat-absorbing copper pipe and the heat-dissipating copper pipe. During the circulation process, the coolant flows through the heat-absorbing copper pipe to carry away the heat generated by the communication control cabinet, and then flows through the heat-dissipating copper pipe to dissipate the carried heat, thus achieving efficient heat dissipation.

[0025] When using airflow for heat dissipation, the airflow velocity is relatively fast, and the airflow flowing through the heat dissipation cabinet cannot completely absorb the heat generated inside the cabinet. That is, the heat of the airflow blown out of the air outlet is not very high. By coiling the heat dissipation copper pipe at the air inlet of the exhaust fan, the blown airflow exchanges heat with the heat dissipation copper pipe, which accelerates the heat dissipation of the heat dissipation copper pipe and realizes the synergistic effect of airflow heat dissipation and coolant heat dissipation, making the heat dissipation efficiency of the entire circulating cooling component higher.

[0032] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. The specific embodiments of the present invention are described below to facilitate understanding by those skilled in the art. However, it should be understood that the present invention is not limited to the scope of the specific embodiments. For those skilled in the art, various changes are obvious as long as they fall within the spirit and scope of the present invention as defined and determined by the appended claims. All inventions utilizing the concept of the present invention are protected.

[0033] like Figure 1 As shown, this embodiment provides a mobile base station heat dissipation duct and liquid cooling synergistic cooling device. This device employs both airflow cooling and coolant cooling methods, which work synergistically to achieve high heat dissipation efficiency. Specifically, it includes:

[0034] 1. Heat dissipation cabinet; 2. Communication control cabinet; 3. Air intake assembly; 4. Air exhaust assembly; and 5. Circulating cooling assembly.

[0035] The heat dissipation cabinet 1 houses the communication control cabinet 2. An air intake assembly 3 is located at the bottom of the heat dissipation cabinet 1. Two sets of air outlet assemblies 4 are installed on each side of the heat dissipation cabinet 1. When the mobile base station is operating, air enters the heat dissipation cabinet 1 through the air intake assembly 3 and flows out through the air outlet assemblies 4, carrying away the heat generated inside the cabinet during its flow. A circulating cooling assembly 5 is installed on the air outlet assembly 4. As air flows out of the air outlet assembly 4, it cools the circulating cooling assembly 5, carrying away the heat from the coolant inside the circulating cooling assembly 5. The coolant continues to circulate within the circulating cooling assembly 5, further cooling the communication control cabinet 2. The airflow accelerates the dissipation of heat from the coolant, achieving a synergistic effect of airflow cooling and coolant cooling, resulting in good heat dissipation and low cost.

[0036] like Figure 2 As shown, the air outlet assembly 4 includes a fan frame 41 and an exhaust fan 42. The fan frame 41 is installed inside the heat dissipation cabinet 1. Three exhaust fans 42 are installed in the three mounting cavities in the middle of the fan frame 41. Three air outlet holes 11 are opened on the side wall of the heat dissipation cabinet 1 at positions corresponding to the three exhaust fans 42. When the exhaust fans 42 are working, they drive the air inside the heat dissipation cabinet 1 to be discharged through the air outlet holes 11, so that the heat inside the cabinet can be dissipated in a controlled manner.

[0037] The circulating cooling component 5 includes a heat-absorbing copper pipe 51 and a heat-dissipating copper pipe 52. One end of the heat-absorbing copper pipe 51 is connected to one end of the heat-dissipating copper pipe 52; the other end of the heat-dissipating copper pipe 52 is connected to the inlet of the circulating pump 53, and the other end of the heat-absorbing copper pipe 51 is connected to the outlet of the circulating pump 53. The heat-absorbing copper pipe 51 is installed on the side of the communication control cabinet 2, and the heat-dissipating copper pipe 52 is installed at the air inlet of the three exhaust fans 42 by three sets of limiting components. The circulating pump 53 drives the coolant to circulate between the heat-absorbing copper pipe 51 and the heat-dissipating copper pipe 52. When flowing through the heat-absorbing copper pipe 51, the coolant absorbs the heat generated by the communication control cabinet 2, and when flowing through the heat-dissipating copper pipe 52, the heat is dissipated. Furthermore, the heat-dissipating copper pipe 52 is located at the air inlet of the exhaust fans 42, which further accelerates the heat dissipation on the heat-dissipating copper pipe 52 when the airflow passes through it, thereby improving the heat dissipation efficiency.

[0038] The coolant in the circulating cooling component 5 is preferably water.

[0039] The limiting assembly includes a limiting ring 54, which is fixed around the mounting cavity of the fan frame 41 by screws; the heat dissipation copper pipe 52 is arranged radially through the through holes on the side walls of the three limiting rings 54; the outer side of the limiting ring 54 is threaded, and a pressure ring 55 is threaded onto the outer thread of the limiting ring 54.

[0040] like Figure 3As shown, the heat dissipation copper pipe 52 is located in the middle of the limiting ring 54 with a spiral bend in the pipe body; the heat dissipation copper pipe 52 has a large heat dissipation area due to the spiral bend; at the same time, the heat exchange area with the airflow is also large, which can dissipate the heat carried by the coolant in the heat dissipation copper pipe 52 more quickly.

[0041] Two elastic lugs 43 are connected to each side of the fan frame 41. The ends of the two elastic lugs 43 pass through the strip holes on the side wall of the heat dissipation cabinet 1 and are snapped into the edge of the strip holes. When installing the fan frame 41, the two elastic lugs 43 are directly snapped into the strip holes on the side wall of the heat dissipation cabinet 1. Under the action of elasticity, the elastic lugs 43 are snapped into the strip holes. The installation is simple and convenient.

[0042] Each air outlet 11 is equipped with a dust cover 12.

[0043] The air intake assembly 3 includes an air filter 31, which is installed in the air intake holes on both sides of the heat dissipation cabinet 1. The air filter 31 filters the air entering the heat dissipation cabinet 1 to prevent dust and debris from being blown into the cabinet.

[0044] An electrical mounting bracket 6 is installed inside the heat dissipation cabinet 1, and the electrical mounting bracket 6 is located below the communication control cabinet 2. Air enters through the air inlet, passes through the electrical mounting bracket 6, and is then blown out by the exhaust fan 42. During the airflow, the electrical equipment installed on the electrical mounting bracket 6 is cooled.

[0045] like Figure 4 As shown, the front of the heat dissipation cabinet 1 is movably connected to two cabinet doors 13; each cabinet door 13 is equipped with an observation window 14.

[0046] The working principle of this embodiment is as follows:

[0047] When the mobile base station heat dissipation duct and liquid cooling synergistic cooling device are working, the airflow enters from the air inlet of the heat dissipation cabinet 1 and is then blown out from the air outlet 11 by the exhaust fan 42, carrying away the heat generated inside the cabinet during its flow. Due to the relatively fast airflow velocity, the airflow flowing through the heat dissipation cabinet 1 cannot completely absorb the heat generated inside the cabinet, meaning that the heat of the airflow blown out from the air outlet 11 is not very high. The heat dissipation copper pipe 52 is coiled and positioned at the air inlet of the exhaust fan 42, and the blown airflow exchanges heat with the heat dissipation copper pipe 52, accelerating the heat dissipation on the heat dissipation copper pipe 52. This achieves the synergistic effect of airflow cooling and coolant cooling, making the overall cooling efficiency of the circulating cooling component 5 higher.

Those skilled in the art can make various other specific modifications and combinations based on these technical teachings disclosed in this invention without departing from the essence of this invention, and these modifications and combinations are still within the scope of protection of this invention.
