Abstract
Description
Technical Field
[0001] This utility model relates to the field of communication base station cabinet technology, specifically to an immersion liquid cooling heat dissipation component for communication base stations. Background Technology
[0002] The core components of a communication base station include base station chips, base station antennas, radio frequency (RF) components, filters, network optimization equipment, power amplifiers (PAs), printed circuit boards (PCBs), and backup power supplies. The power devices and backup power supplies within the base station are typically housed in an outdoor integrated cabinet. Lithium batteries are generally used as backup batteries. To increase the lifespan of these backup batteries, heat dissipation is achieved through a common method: immersion liquid cooling. This involves submerging the batteries in an insulating cooling liquid for direct cooling, increasing the heat dissipation area, improving temperature uniformity of individual battery cells and battery modules, and ultimately extending battery life.
[0003] The backup battery cooling device in the communication base station cabinet is installed at the bottom of the cabinet. The coolant used for the battery needs to be replaced after a period of use. However, the internal space of the cabinet is narrow and the operating space is small. Once the coolant needs to be replaced, the entire cooling component can only be disassembled from the cabinet, which increases the labor intensity, reduces maintenance efficiency, and is inconvenient for later replacement of coolant and maintenance of the battery. Therefore, an immersion liquid cooling heat dissipation component for communication base stations is proposed to solve the above-mentioned problems. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides an immersion liquid cooling heat dissipation component for communication base stations. It has the advantages of not requiring disassembly of the cooling component, facilitating coolant replacement and battery maintenance, and solving the problems of cumbersome disassembly, inconvenience in coolant replacement, increased labor intensity, and reduced maintenance efficiency of existing immersion liquid cooling components.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an immersion liquid cooling heat dissipation component for a communication base station, comprising a cabinet, a partition fixedly installed on the inner side of the cabinet, and sliding grooves located below the partitions on both the left and right inner walls of the cabinet. Mounting plates are slidably installed on the inner sides of the two sliding grooves. A cooling box is fixedly installed on the top of the mounting plate. A sealing cover is fixedly installed on the top of the cooling box by bolts. A battery located inside the cooling box is fixedly installed on the bottom of the sealing cover. A liquid storage tank is fixedly installed on the top of the mounting plate. A variable frequency pump located between the cooling box and the liquid storage tank is fixedly installed on the top of the mounting plate. The input and output ends of the variable frequency pump are respectively connected to the cooling box and the liquid storage tank.
[0006] Furthermore, a heat exchange mechanism is provided on the top of the partition, the heat exchange mechanism includes finned heat dissipation tubes fixedly installed on the top of the partition, a heat dissipation fan is fixedly installed on the top of the finned heat dissipation tubes, and both ends of the finned heat dissipation tubes extend to the bottom of the partition and are respectively connected to the top of the cooling tank and the liquid storage tank through flexible hoses.
[0007] Furthermore, the top of the liquid storage tank is provided with a liquid inlet, and the left side of the liquid storage tank is provided with a liquid outlet.
[0008] Furthermore, a cooling air conditioner is provided on the right side of the cabinet, and ventilation openings are provided on both the left and right sides of the cabinet, with the cooling air conditioner connected to the cabinet through the ventilation openings.
[0009] Furthermore, the rear end of the mounting plate is T-shaped, and the front end dimensions of the sliding grooves on both sides are smaller than the rear end dimensions of the mounting plate.
[0010] Furthermore, the mounting plate is provided with a number of rollers on both the left and right sides of its bottom, and the rollers on both sides are arranged in a row and fit against the inner bottom wall of the sliding groove on both sides.
[0011] Furthermore, the bottom of the mounting plate has two movable grooves distributed to the left and right, and support feet are rotatably installed on the inner side of the two movable grooves.
[0012] Compared with the prior art, the present invention provides an immersion liquid cooling heat dissipation component for communication base stations, which has the following beneficial effects:
[0013] This immersion liquid cooling heat dissipation component for communication base stations allows the cooling tank and liquid storage tank on top of the mounting plate to be moved out of the cabinet by pulling the mounting plate outward. The support feet at the bottom of the mounting plate are rotated to support it, and the waste coolant is discharged through the drain port. At the same time, the variable frequency pump draws the coolant in the cooling tank into the liquid storage tank for discharge. This solves the problems of existing immersion liquid cooling components, such as cumbersome disassembly, inconvenience in replacing coolant, increased labor intensity, and reduced maintenance efficiency.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0020] Please see Figures 1 to 4 This embodiment of an immersion liquid cooling heat dissipation component for a communication base station includes a cabinet 1. A partition 2 is fixedly installed on the inner side of the cabinet 1. Slide grooves 3 are formed on both the left and right inner walls of the cabinet 1, located below the partition 2. Mounting plates 4 are slidably installed on the inner sides of the two slide grooves 3. A cooling tank 5 is fixedly installed on the top of the mounting plate 4. A sealing cover 6 is fixedly installed on the top of the cooling tank 5 by bolts. A battery 7 located inside the cooling tank 5 is fixedly installed on the bottom of the sealing cover 6. A liquid storage tank 8 is fixedly installed on the top of the mounting plate 4. A variable frequency pump 9 is fixedly installed between the cooling tank 5 and the liquid storage tank 8. The input and output ends of the variable frequency pump 9 are respectively connected to the cooling tank 5 and the liquid storage tank 8. An inlet 11 is provided on the top of the liquid storage tank 8 for injecting new coolant. A drain 12 is provided on the left side of the liquid storage tank 8. The damaged coolant is discharged through the drain port 12; the rear end of the mounting plate 4 is T-shaped, and the front end of the sliding grooves 3 on both sides is smaller than the rear end of the mounting plate 4. The rear end of the mounting plate 4 and the sliding grooves 3 form a limit to prevent the mounting plate 4 from detaching from the cabinet 1 when it is pulled outward; several rollers 14 are provided on both the left and right sides of the bottom of the mounting plate 4. The rollers 14 on both sides are arranged in a row and fit against the inner bottom wall of the sliding grooves 3 on both sides. The rollers 14 at the bottom of the mounting plate 4 can reduce the friction generated when pulling. There are two movable grooves 15 distributed on the left and right sides at the bottom of the mounting plate 4. The inner side of the two movable grooves 15 is rotatably installed with support feet 16. When the mounting plate 4 is fully pulled out, it can be rotated out by the support feet 16 to form support with the ground, improving the stability of the mounting plate 4 when it is pulled out; a handle can be provided on the front side of the mounting plate 4 to facilitate its pulling out.
[0021] The partition 2 is equipped with a heat exchange mechanism 10 at its top. The heat exchange mechanism 10 includes a finned heat exchange tube 101 fixedly installed at the top of the partition 2. A cooling fan 102 is fixedly installed at the top of the finned heat exchange tube 101. Both ends of the finned heat exchange tube 101 extend to the bottom of the partition 2 and are connected to the top of the cooling tank 5 and the liquid storage tank 8 respectively through hoses 103. The coolant overflowing from the cooling tank 5 flows into the finned heat exchange tube 101 through the hoses 103. The cooling fan 102 dissipates heat from the finned heat exchange tube 101, thereby cooling the coolant inside the finned heat exchange tube 101. The cooled coolant flows back to the liquid storage tank 8 and is then transported back to the cooling tank 5 by the variable frequency pump 9 to dissipate heat from the battery 7, forming a cooling circuit. A cooling air conditioner 13 is provided on the right side of the cabinet 1. Heat dissipation vents are provided on both the left and right sides of the cabinet 1, and the cooling air conditioner 13 is connected to the cabinet 1 through the heat dissipation vents. The cooling air conditioner 13 transfers the heat exhausted by the cooling fan 102 to the outside of the cabinet 1.
[0022] It should be noted that the output mode of the variable frequency pump 9 can be either suction or suction. The pipe at one end of the variable frequency pump 9 inside the cooling tank 5 is located at the bottom of the cooling tank 5, which makes it easy to completely suck out the coolant in the cooling tank 5 when discharging the coolant. The length of the hose 103 must meet the travel of the mounting plate 4. The partition 2 is above the electrical compartment, which is used to place the main control board and power modules and other power devices. The mounting plate 4 has a wiring hole, and the battery output line on the sealing cover 6 enters the electrical compartment through the wiring hole.
[0023] The working principle of the above embodiments is as follows:
[0024] When the coolant needs to be replaced, pull the mounting plate 4 outward, and the cooling tank 5 and the reservoir 8 on the top of the mounting plate 4 will move out of the cabinet 1. Rotate the support foot 16 at the bottom of the mounting plate 4 to support it, and drain the bad coolant through the drain port 12. At the same time, the variable frequency pump 9 will suck the coolant in the cooling tank 5 into the reservoir 8 for drainage. After drainage, new coolant will be poured in through the inlet 11. After maintenance, retract the support foot 16 into the movable slot 15 and push the mounting plate 4 inward to return it to the cabinet 1.
[0025] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that achieves the desired beneficial effect can be implemented. Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer that performs control functions. Those skilled in the art can control the electrical components through simple programming, and the existing disclosed power connection technologies are common knowledge in the field. Therefore, this embodiment will not elaborate further on their specific structural composition and working principles.
