[0046] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0047] Example 1:

[0048] like Figure 1 As shown, the present invention provides a heat exchange device suitable for 5G communication base station cabinets, comprising:

[0049] Liquid cooling plates are installed at the bottom of each electronic device in cabinet 1, and the liquid cooling plates are equipped with circulation channels to contain liquid metal;

[0050] The temperature monitoring unit uses temperature sensors to detect the temperature status of each electronic device inside cabinet 1.

[0051] The air-cooled circulation assembly includes a cooling jacket 2, a circulation pipe 3, and an air intake 4. The cooling jacket 2 is located outside the cabinet 1 and is used to reduce the high-temperature gas inside it. The circulation pipe 3 is connected between the cooling jacket 2 and the cabinet 1 and is used to transport airflow between the cabinet 1 and the cooling jacket 2. The air intake 4 is connected to the circulation pipe 3 and is located inside the cabinet 1. Multiple air intakes 4 are respectively facing each electronic device.

[0052] The working principle and beneficial effects of the above technical solution are as follows:

[0053] The application provides a heat exchange equipment suitable for a 5G communication base station cabinet, liquid cooling plates and air cooling circulation components are arranged, the liquid cooling plates are arranged at the bottoms of electronic devices in the cabinet 1, heat on the electronic devices is absorbed and transmitted to the outside of the cabinet 1 through the liquid metal (GaInSn, etc.) flowing in the liquid cooling plates, so that heat dissipation is realized. The air cooling circulation components are arranged on the cabinet 1, the air suction heads 4 of the air cooling circulation components are opposite to the electronic devices, when local heat dissipation of any one or more of the devices is needed, the air cooling circulation components are started, the electric control valves are arranged at the connection positions of the circulating pipelines 3 and the air suction heads 4, the electric control valves corresponding to the air suction heads 4 in the heat dissipation position are opened, high-temperature gas is sucked out through the air suction heads 4, the circulating pipelines 3 transport the high-temperature gas to the cooling jackets 2 to be cooled, and then the low-temperature gas is circulated back to the cabinet 1. The temperature data of the electronic devices in the cabinet 1 are detected by the temperature sensors in real time, and the liquid cooling heat dissipation and the air cooling heat dissipation process are controlled.

[0054] Through the above structural design, the liquid cooling plates and the air cooling circulation components are cooperatively controlled to dissipate heat of high-power electronic devices in the 5G communication base station cabinet; the liquid metal flow channel is arranged in the liquid cooling plate, the liquid metal efficiently absorbs heat at the bottoms of the devices by virtue of super-high thermal conductivity, low viscosity flowability and latent heat of phase change; when local high temperature is detected by the temperature monitoring unit, the air cooling circulation components are started to directionally absorb high-temperature gas; the design of the double heat dissipation systems guarantees uniformity and significantly improves thermal reliability under extreme working conditions, reduces energy consumption and guarantees heat dissipation efficiency.

[0055] Embodiment 2

[0056] On the basis of the above embodiment 1, the cabinet 1 is further provided with a liquid cooling pump and a radiator, the liquid cooling pump is used for driving the liquid metal in the circulating flow channel to flow, and the radiator is arranged at the heat dissipation end of the liquid cooling plate.

[0057] The working principle and beneficial effects of the above technical solution are as follows:

[0058] The liquid cooling pump is used for providing power for the liquid metal flowing in the liquid cooling plate, the liquid metal absorbs heat on the electronic devices and transports the heat to the heat dissipation end when flowing, the heat is dissipated through the radiator, and the liquid metal is circulated back after the temperature is reduced, so that circulating heat dissipation is realized.

[0059] Embodiment 3

[0060] On the basis of the above embodiment 1, the controller controls the liquid cooling plate and the air cooling circulation component to operate according to the temperature data collected by the temperature monitoring unit, and the specific steps are as follows:

[0061] The temperature sensor detects temperature values of the electronic devices to form a temperature set of the current detection node;

[0062] When all temperature data in the temperature set are less than 45°C, the liquid cooling plate is activated to dissipate heat at the first preset power.

[0063] When any temperature data in the temperature set is greater than 45℃, the air-cooling circulation component is activated at the same time, and the air intake 4 at the electronic device corresponding to this temperature data is turned on to perform local heat dissipation at this electronic device.

[0064] When more than 1 / 3 of the temperature data in the temperature set is greater than 85°C, the liquid cooling plate will be operated at the second preset power for heat dissipation. The second preset power is higher than the first preset power.

[0065] The working principle and beneficial effects of the above technical solution are as follows:

[0066] The controller manages the heat exchange process based on real-time temperature monitoring data, intelligently linking the liquid cooling plate and the air-cooled circulation component. When all temperatures within the temperature set are below 45°C, the liquid cooling plate is activated to operate at a first preset power for heat dissipation, maintaining basic heat dissipation and minimizing energy loss during the heat dissipation process. When any temperature within the temperature set exceeds 45°C, the air-cooled circulation component is activated simultaneously, and the suction head 4 at the corresponding electronic device is turned on for localized heat dissipation. The airflow is positively correlated with temperature; the higher the local temperature, the greater the airflow. Localized cooling is achieved through air cooling, ensuring effective heat dissipation while reducing energy consumption. When more than one-third of the temperature data within the temperature set exceeds 85°C, it indicates that increasing air cooling is still insufficient for effective cooling. The backup cooling mechanism is then triggered, and the liquid cooling plate operates at a second preset power for heat dissipation, further improving the equipment's heat dissipation efficiency.

[0067] Example 4:

[0068] like Figures 2-4 As shown, based on the above embodiment 1, the cooling jacket 2 is installed outside the cabinet 1 via the support leg 11. A heat exchange tube 12 is provided in the center of the cooling jacket 2. The bottom and top of the heat exchange tube 12 are respectively set as the air inlet and air outlet. The heat exchange tube 12 is connected to the circulation pipeline 3. A circulation pump is provided on the circulation pipeline 3.

[0069] The working principle and beneficial effects of the above technical solution are as follows:

[0070] The circulating pump is used to provide power for the gas flow in the circulating pipeline 3. The high-temperature gas drawn in by the suction head 4 is transported to the heat exchange tube 12 through the circulating pipeline 3. The heat exchange tube 12 is cooled by the cooling jacket 2, and then the cooled gas returns to the cabinet 1 through the circulating pipeline 3.

[0071] Example 5:

[0072] like Figures 2-4As shown, based on the above embodiment 4, the cooling jacket 2 includes: an inner jacket 13 and an outer jacket 14. The heat exchange tube 12, the inner jacket 13 and the outer jacket 14 are coaxially arranged from the inside to the outside. A heat absorption channel 15 is formed between the heat exchange tube 12 and the inner jacket 13, and a heat dissipation channel 16 is formed between the inner jacket 13 and the outer jacket 14. The tops of the heat absorption channel 15 and the heat dissipation channel 16 are connected. The inner jacket 13 is made of heat insulation material, and the outer wall of the outer jacket 14 is provided with heat dissipation fins.

[0073] Coolant is provided in the heat absorption channel 15 and the heat dissipation channel 16. Coolant circulation pump 10 is connected to the bottom end of the cooling jacket 2. Coolant circulation pump 10 is connected to the heat absorption channel 15 and the heat dissipation channel 16.

[0074] The working principle and beneficial effects of the above technical solution are as follows:

[0075] The cooling jacket 2 is configured with an inner and outer double-layer structure, consisting of an inner jacket 13 and an outer jacket 14. The coolant circulation pump 10 introduces coolant from the bottom of the inner jacket 13, which then passes through the heat absorption channel 15 and comes into full contact with the heat exchange tube 12, absorbing the heat from the high-temperature gas inside the heat exchange tube 12. The coolant then enters the heat dissipation channel 16 between the inner jacket 13 and the outer jacket 14 through the connecting port at the top of the outer jacket 14. The inner jacket 13 blocks the heat exchange between the heat absorption channel 15 and the heat dissipation channel 16, causing most of the heat from the coolant in the heat dissipation channel 16 to dissipate through the heat sinks outside the outer jacket 14. The cooled coolant then flows back to the coolant circulation pump 10 and is pumped back in. The cooling jacket 2, with its double-layer design, is fitted onto the heat exchange tube 12. Heat exchange occurs along the airflow circulation path. The circumferentially arranged flow channel absorbs heat on the inner side and dissipates heat on the outer side, making full contact with the heat exchange tube 12 to effectively improve the heat exchange effect and achieve rapid cooling of the airflow.

[0076] Example 6:

[0077] like Figures 2-4 As shown, based on the above embodiment 5, a partition plate 17 is sleeved on the heat exchange tube 12. Multiple partition plates 17 are arranged in a ring structure and are spaced apart on the outside of the heat exchange tube 12, dividing the heat absorption channel 15 into multiple chambers, and the chambers are interconnected.

[0078] The inner wall of the inner jacket 13 is provided with multiple layers of locking blocks 18 along the axial direction, and each layer of locking blocks 18 corresponds to the position of the partition plate 17. Multiple locking blocks 18 in each layer are evenly arranged along the circumference of the inner jacket 13. The locking blocks 18 are connected to the outer ring of the partition plate 17 to coaxially install the partition plate 17 between the inner jacket 13 and the heat exchange tube 12.

[0079] Multiple first connecting grooves 19 are spaced apart on the heat exchange tube 12. The first connecting grooves 19 are arranged in a ring and located inside the partition plate 17.

[0080] Multiple second connecting grooves 21 are spaced apart on the inner wall of the inner sleeve 13. The second connecting grooves 21 are arranged in a ring and located outside the partition plate 17. The first connecting grooves 19 and the second connecting grooves 21 are alternately arranged at each layer of partition plate 17.

[0081] The working principle and beneficial effects of the above technical solution are as follows:

[0082] The partition 17 divides the heat absorption channel 15 into multiple chambers, which are connected by a connecting groove. When the coolant enters from the bottom of the inner jacket 13, it flows upward. Due to the obstruction of the partition 17, the coolant flow rate decreases and fills the separated chamber, allowing the coolant in this chamber to fully contact the heat exchange tube 12. The coolant then flows upward through the second connecting groove 21 at the bottom. The coolant then enters the upper chamber, filling it and ensuring full contact with the heat exchange tube 12. The coolant then flows upward through the first connecting groove 19 at the top. The coolant circulates through the above process until it reaches the top of the inner jacket 13 and flows out into the heat dissipation channel 16.

[0083] Through the above structural design, multiple partition plates 17 divide the heat absorption channel 15 into multiple chambers. The connecting grooves between each chamber are relatively small in size, allowing the coolant to preferentially fill the chambers and ensuring sufficient contact and heat exchange between the coolant and the heat exchange tube 12. The staggered arrangement of the first connecting groove 19 and the second connecting groove 21 increases the flow of the coolant in both the internal and external directions, improves the heat absorption efficiency of the coolant, and solves the problem that the coolant mainly absorbs heat through the internal side, resulting in limited heat absorption effect.

[0084] Example 7:

[0085] like Figures 2-4 As shown, based on the above embodiment 6, the inner wall of the inner sleeve 13 is provided with a plurality of retaining rings 22 at intervals along the axial direction. The retaining rings 22 are located on the layer where the second connecting groove 21 is provided and are arranged above the second connecting groove 21.

[0086] The working principle and beneficial effects of the above technical solution are as follows:

[0087] The baffle ring 22 is positioned above the second connecting groove 21. When the coolant passes through the second connecting groove 21, it flows towards the heat exchange tube 12 under the obstruction of the baffle ring 22 and concentrates near the heat exchange tube 12. Then it flows upward close to the heat exchange tube 12, thereby improving the heat exchange effect.

[0088] Example 8:

[0089] like Figures 2-4 As shown, based on the above embodiment 5, the outer wall of the inner jacket 13 is provided with a plurality of first baffle rings 23 at intervals along the axial direction;

[0090] The inner wall of the outer jacket 14 is provided with a plurality of second baffle rings 24 in the axial direction;

[0091] The widths of the first baffle ring 23 and the second baffle ring 24 are smaller than the distance between the inner jacket 13 and the outer jacket 14, and the first baffle ring 23 and the second baffle ring 24 are arranged alternately.

[0092] The working principle and beneficial effects of the above technical solution are:

[0093] The first baffle ring 23 and the second baffle ring 24 are arranged alternately to form a curved heat dissipation flow channel 16. After the cooling liquid enters the heat dissipation flow channel 16, it flows downward while flowing horizontally, prolongs the flow path of the cooling liquid, makes the cooling liquid fully contact with the outer wall of the inner jacket 13, and then dissipates heat through the heat dissipation fins, thereby improving the heat dissipation and cooling effect.

[0094] Embodiment 9:

[0095] As shown in Figure 5 , Figure 6 Based on the above-mentioned embodiment 1, the air suction head 4 comprises:

[0096] a first conical cylinder 31, a dust collecting box 32 and an air suction cylinder 33 connected in sequence, the first conical cylinder 31 and the air suction cylinder 33 are smaller in diameter at the end close to the dust collecting box 32, the first conical cylinder 31 is in communication with the dust collecting box 32, and the other end of the first conical cylinder 31 is connected with the circulating pipeline 3 and a sealing ring 30 is arranged at the connection position; when the air suction head 4 is arranged at the top of the cabinet 1, the air suction port of the air suction cylinder 33 faces downward, and when the air suction head 4 is arranged at the front or rear of the cabinet 1, the air suction cylinder 33 is connected with the dust collecting box 32 through an elbow pipe and the air suction port is arranged horizontally;

[0097] a second conical cylinder 34 coaxially arranged in the first conical cylinder 31, a through hole adapted to the second conical cylinder 34 is arranged at the top end of the first conical cylinder 31, an airflow hole 35 is arranged at the bottom of the second conical cylinder 34, and a filter core 36 is arranged in the second conical cylinder 34;

[0098] a filter core stop ring 37, the filter core stop ring 37 is press-connected to the top end of the second conical cylinder 34, and a plurality of limiting pieces 38 are uniformly arranged on the filter core stop ring 37 in the circumferential direction;

[0100] an air suction pipe 40 connected between the first conical cylinder 31 and the air suction cylinder 33.

[0101] The working principle and beneficial effects of the above technical solution are:

[0102] When the suction head 4 is used, the circulating pump on the circulating pipeline 3 is started to generate suction force, and the high-temperature airflow is sucked through the suction cylinder 33, which is designed in a conical shape to improve the gathering effect of the airflow. The airflow flows into the first conical cylinder 31 through the suction pipe 40, and a cyclone is formed between the first conical cylinder 31 and the second conical cylinder 34. The tapered structure of the conical cylinder accelerates the airflow, and the dust particles in the airflow collide with the inner wall of the first conical cylinder 31. The heavier dust particles fall along the inner wall of the first conical cylinder 31 into the dust collecting box 32. The airflow passes through the filter core 36 through the through hole at the bottom of the second conical cylinder 34, and the filter core 36 filters out small dust particles. Then, the airflow enters the circulating pipeline 3 through the bottom of the second conical cylinder 34. The filter core 36 needs to be replaced after a period of use. The rotating filter core stop ring 37 is used to disengage the limiting piece 38 from the limiting block 39. After the filter core stop ring 37 is removed, the filter core 36 can be replaced.

[0103] Through the above structure design, the filter and dust collecting structure is arranged at the suction head 4 to pre-removes the dust particles mixed in the high-temperature gas, prevents the blockage when passing through the circulating pipeline 3 and the heat exchange pipe 12, improves the reliability of the equipment, and the tapered structure of the conical cylinder accelerates the airflow and improves the filtering effect of the dust particles. The dust collecting box 32 can be provided with a sealing door, which can be used to collect and clean dust after a period of use, thereby reducing the maintenance frequency of the equipment.
