Description

Technical Field

[0001] This invention relates to the field of server heat dissipation technology, specifically to a server liquid cooling radiator. Background Technology

[0002] A server is a type of computer that runs faster, has a higher load capacity, and is more expensive than a regular computer. Servers provide computing or application services to other clients on a network. Servers have high-speed CPU computing power and can operate reliably for long periods of time. Servers generate a lot of heat during operation, so liquid cooling radiators are used to dissipate heat from the server.

[0003] Traditional liquid cooling radiators mainly consist of several key structures, including a heat sink, server motherboard, liquid outlet, metal block, liquid outlet pipe, mounting base, mounting plate, sealing ring, and water pump. Through the stable and continuous flow of liquid in the outlet pipes and a highly efficient heat exchange process, they can quickly absorb and remove a large amount of heat generated inside the server and its surrounding environment, thereby effectively achieving temperature control and thermal management of the entire system.

[0004] However, due to limitations imposed by flow conditions and spatial structure, the liquid inside the outlet pipe cannot fully absorb the heat generated by the server. Only the liquid closest to the server can directly contact the heat source and absorb some heat, while the remaining liquid, due to distance or flow pattern, cannot achieve effective heat exchange. Furthermore, the liquid that has already absorbed heat is unlikely to reach heat saturation and cannot absorb more heat. In addition, due to the forced flow driven by the water pump, the liquid flows at a high speed and has a short residence time in the pipe, failing to make sufficient contact with the server to complete effective heat transfer. Ultimately, this results in insufficient heat exchange. Therefore, a server liquid cooling radiator is proposed. Summary of the Invention

[0005] Therefore, this invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes a server liquid cooling radiator that can control the duration of liquid contact with the server based on the heat around the server, thereby improving the liquid cooling effect.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a server liquid cooling radiator, comprising a cabinet, characterized in that: the cabinet is composed of a constraint beam and a load-bearing plate forming a frame for storing the server, and the frame is equipped with a heat dissipation component capable of cooling the server during operation. The heat dissipation assembly includes two sets of liquid cooling plates installed on the top of each set of load-bearing plates. Each liquid cooling plate is composed of an upper plate frame and a lower plate frame stacked on top of each other. The side of the upper plate frame and the lower plate frame that are in contact with each other forms a unit cavity. Flow dividers are provided at equal intervals along the length of the unit cavity. The flow dividers form multiple sets of flow channels within the unit cavity. Each set of flow channels has two sets of semi-spiral strips fixed to the upper plate frame and the lower plate frame, respectively. The two sets of semi-spiral strips abut against each other within the flow channel to form a spiral partition. A confluence cavity is formed at both ends of the flow dividers within the unit cavity. The unit cavity is provided with a sealing strip that can change the flow path of the liquid within the multiple sets of flow channels. The top of the cabinet is equipped with a heat dissipation box, and the cabinet is equipped with a return pipe that connects the heat dissipation box and each set of liquid cooling plates near the rear inner wall. The rear inner wall of the cabinet is equipped with a variety of cooling fans for cooling the return pipe.

[0007] As a preferred technical solution, the heat dissipation component further includes a positioning frame sleeved on the bottom of the liquid cooling plate, and the positioning frame is detachably connected to the load-bearing plate by bolts.

[0008] As a preferred technical solution, the end of the liquid cooling plate is provided with two sets of connecting pipes extending into the unit cavity, and the two sets of connecting pipes respectively deliver liquid for server heat dissipation to the inside and outside of the unit cavity.

[0009] As a preferred technical solution, the bottom of the lower frame is provided with a storage base for storing each set of seals. The bottom of the lower frame is provided with a clearance groove for the seals to slide in and out. Two sets of guide telescopic rods are fixed inside the storage base and extend into the bottom of the seal. A first electromagnet is fixed to the bottom of the seal with screws. A second electromagnet is fixed inside the storage base at a position corresponding to the first electromagnet. An elastic membrane is sleeved on the top of the storage base outside the seal. The elastic membrane has frame edges on both the top and bottom sides. The two sets of frame edges can position the elastic membrane in a taut state.

[0010] As a preferred technical solution, a return pipe connected to the liquid cooling plate is provided on one side of the return pipe. Both the return pipe and the return pipe are connected to the heat sink via a connecting pipe. The heat sink is equipped with a pump that can deliver liquid into the return pipe.

[0011] As a preferred technical solution, both the return pipe and the reflux pipe are provided with an outer frame. The front and back of the outer frame are provided with heat dissipation windows at positions corresponding to the lateral part of the return pipe, and a filter screen is fixed inside each heat dissipation window.

[0012] As a preferred technical solution, the front surface of the cabinet is provided with two sets of fixed bearings, and a cabinet door that fits against the front surface of the cabinet is rotatably provided between the two sets of bearings. The surface of the cabinet door is provided with two sets of iron mesh for ventilation, and a temperature sensor that can control the start and stop of the heat dissipation component is installed on the front surface of the cabinet at the position between the two sets of iron mesh.

[0013] As a preferred technical solution, the outer wall of the folding tube is fitted with heat dissipation fins in the transverse part, and the heat dissipation fins are equidistantly distributed along the axial direction of the folding tube.

[0014] In summary, the present invention has the following main beneficial effects: This invention, by setting flow dividers and semi-spiral strips inside the liquid cooling plate, not only forms a continuous spiral strip structure, but also further divides the liquid into multiple flow channels, thereby extending the overall flow path of the cooling liquid inside the liquid cooling plate. This increases the contact area between the liquid and the heat-generating surface, effectively improving the heat exchange efficiency. It allows the liquid inside the liquid cooling plate to exchange heat with the server's heat-generating components for a longer time and more fully, more efficiently absorbing and carrying away the large amount of heat generated during server operation, ultimately achieving a better heat dissipation effect. Furthermore, as the server load inside the cabinet increases and the ambient temperature gradually rises, it can automatically switch to a longer flow channel mode, extending the residence time of the coolant in the liquid cooling plate, enhancing heat exchange efficiency, and always matching the current thermal load of the server, thereby improving the responsiveness and targeting of heat dissipation, and achieving a more efficient and stable heat dissipation and cooling effect; the combined use of the heat sink and cooling fan can further cool the liquid that has absorbed heat, ensuring that the liquid flowing back into the liquid cooling plate achieves a better heat exchange effect.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0018] The embodiments of the present invention will now be described.

[0019] A server liquid cooling radiator, as shown in Figures 1 to 12. Figure 12 The cabinet 100 includes a frame for storing servers, which is composed of constraint beams 120 and load-bearing plates 130, and a heat dissipation component 200 is installed inside the frame to cool the servers when they are working. The heat dissipation assembly 200 includes two sets of liquid cooling plates 210 installed on the top of each set of load-bearing plates 130. The liquid cooling plate 210 is composed of an upper plate frame 211 and a lower plate frame 212 stacked on top of each other. The side of the upper plate frame 211 and the lower plate frame 212 that are in contact with each other forms a unit cavity 270. Diverting strips 240 are provided at equal intervals along the length of the unit cavity 270. The diverting strips 240 form multiple sets of flow channels 260 in the unit cavity 270. Each set of flow channels 260 is provided with two sets of semi-fan spiral strips 250 that are fixed to the upper plate frame 211 and the lower plate frame 212 respectively. The two sets of semi-fan spiral strips 250 abut against each other in the flow channel 260 to form a spiral-shaped partition. The unit cavity 270 is formed at both ends of the diverting strips 240 to form a confluence cavity 271. The unit cavity 270 is provided with a sealing strip 234 that can change the flow path of the liquid in the multiple sets of flow channels 260. The top of the cabinet 100 is equipped with a heat dissipation box 280. Inside the cabinet 100, near the rear inner wall, there is a folding pipe 292 that connects the heat dissipation box 280 and each set of liquid cooling plates 210. Various cooling fans 150 for cooling the folding pipes 292 are installed on the rear inner wall of the cabinet 100.

[0020] The end of the liquid cooling plate 210 is provided with two sets of connecting pipes 213 extending into the unit cavity 270. The two sets of connecting pipes 213 respectively deliver liquid for server heat dissipation to the inside and outside of the unit cavity 270.

[0021] The bottom of the lower frame 212 is provided with a storage base 231 for storing each set of seals 234. The bottom of the lower frame 212 is provided with a clearance groove 216 for the seals 234 to slide in and out. Two sets of guide telescopic rods 237 are fixed inside the storage base 231 and extend into the bottom of the seals 234. The bottom of the seals 234 is fixed with screws to a first electromagnet 235. A second electromagnet 236 is fixed inside the storage base 231 at a position corresponding to the first electromagnet 235. An elastic membrane 238 is sleeved on the top of the storage base 231 outside the seals 234. The outer side of the elastic membrane 238 is provided with frame 233 on both the top and bottom. The two sets of frame 233 can position the elastic membrane 238 in a taut state, which can ensure that the seals 234 are always tightly fitted after being raised or lowered, so as to avoid coolant leakage at this point.

[0022] One side of the return pipe 292 is provided with a return pipe 293 that is connected to the liquid cooling plate 210. Both the return pipe 292 and the return pipe 293 are connected to the heat sink 280 through the connecting pipe 281. The heat sink 280 is provided with a pump body that can deliver liquid into the return pipe 292. It is worth noting that the two sets of connecting pipes 213 at the end of the liquid cooling plate 210 are connected to the return pipe 292 and the return pipe 293 respectively. Through this connection method, a complete liquid circulation path is formed between the liquid cooling plate 210 and the heat sink 280, so that the coolant can continuously circulate inside the pipe, thereby achieving efficient heat transfer and heat dissipation. The upper frame 211 and the lower frame 212 are detachably connected by screws 215 to facilitate assembly during production. The front surface of the cabinet 100 is provided with two sets of bearing seats 140, and a cabinet door 110 is rotatably mounted between the two sets of bearing seats 140 and attached to the front surface of the cabinet 100. The surface of the cabinet door 110 is provided with two sets of iron mesh for ventilation. A temperature sensor that can control the start and stop of the heat dissipation component 200 is installed on the front surface of the cabinet 100 at the position between the two sets of iron mesh. The cabinet 100 is equipped with a control unit for controlling the start and stop of the heat dissipation component 200.

[0023] The temperature sensor monitors the heat around the server inside the cabinet 100 in real time. When the temperature exceeds the preset safety range, the temperature sensor immediately sends a signal to the control unit of the heat dissipation component 200 to trigger the heat dissipation component 200 to start. At this time, the pump in the heat dissipation box 280 starts to work and pumps the coolant into the return pipe 292 through the connecting pipe 281. The coolant then flows into the unit cavity 270 of the liquid cooling plate 210 and is dispersed through multiple sets of flow channels 260 formed by the diversion strips 240. During the flow process, the coolant absorbs the heat generated by the server. After absorbing the heat, the coolant flows back to the heat sink 280 through the return pipe 293. In the heat sink 280, it is cooled down and then pumped back into the return pipe 292 to form a continuous cooling cycle. In addition, the first electromagnet 235 and the second electromagnet 236 inside the storage base 231 and at the bottom of the seal 234 work under the command of the control unit, adjusting the position of the seal 234 through the guide telescopic rod 237, thereby changing the flow path of the coolant in the flow channel 260, ensuring that the coolant can fully contact and absorb the heat generated by the server; in addition, the cooling fan 150 installed on the rear inner wall of the cabinet 100 also works continuously to assist in cooling the coolant in the return pipe 292, further improving the heat dissipation efficiency of the server inside the cabinet 100, and at the same time accelerating the air exchange between the inside and outside of the cabinet 100, so as to achieve the purpose of efficient heat dissipation of the server; The temperature sensor constantly monitors the heat around the server. When the server is under low load (with moderate ambient temperature), the temperature sensor will adjust accordingly as per the instruction manual. Figure 13 The flow channel in the liquid cooling plate 210 is an integral U-shaped flow channel, which allows the coolant to enter and exit quickly in the liquid cooling plate 210, thereby reducing the residence time and optimizing the heat exchange performance. As the server's workload increases, the surrounding heat continues to rise. Its temperature sensor monitors this in real time and converts the collected temperature data into electrical signals, which are then transmitted to the control unit. The control unit compares and analyzes the received signal strength against a preset threshold, thereby adjusting the displacement of the seal 234 to create various interaction modes with the flow channel 260. This causes dynamic changes in the flow channel structure inside the liquid cooling plate 210, specifically as described in the instruction manual. Figure 13 The basic flow channel layout shown is gradually switched to the attached... Figure 14 The intermediate transitional form shown ultimately reaches the attached Figure 15 The flow channel shown; By adjusting the position of the seal 234 and its relationship with the flow channel, the length and distribution of the coolant's flow path within the liquid cooling plate 210 can be flexibly changed. When the server load is low, a shorter flow channel can achieve rapid circulation and basic heat dissipation. However, when the server gradually enters a high-load operating state, it automatically switches to a longer flow channel mode to extend the coolant's residence time within the liquid cooling plate 210, enhance heat exchange efficiency, and always match the server's current thermal load state, thereby improving the responsiveness and targeting of heat dissipation and achieving a more efficient and stable heat dissipation and cooling effect.

[0024] As per the instruction manual Figure 6 and 7 As shown, wire holes are reserved on the outer sides of both the outer frame 230 and the storage base 231 for connecting the internal electromagnet to the external circuit, thereby achieving mutual repulsion or attraction forces to adjust the position of the seal 234. The first electromagnet 235 and the second electromagnet 236 are electrically connected to the control unit via wires. By changing the direction of the circuit flow, the first electromagnet 235 and the second electromagnet 236 can be controlled to attract or repel each other. Through commands from the control unit, the seal 234 can be precisely controlled to retract downwards into the storage base 231, thus forming the structure described in the appendix to the instruction manual. Figure 13 Appendix Figure 14 and attached Figure 15 As shown, the flow path of the liquid in the final unit cavity 270 is adjusted, and the actual length of the channel through which it flows is shortened accordingly, thereby reducing the workload on the pump body in the heat sink 280 and extending its service life.

[0025] Please refer to this carefully. Figure 3 The heat dissipation assembly 200 also includes a positioning frame 220 sleeved on the bottom of the liquid cooling plate 210. The positioning frame 220 is detachably connected to the load-bearing plate 130 by bolts. The top of the load-bearing plate 130 is provided with a mounting slot 131 for mounting the positioning frame 220.

[0026] The positioning frame 220 enhances the stability of the liquid cooling plate 210 on the load-bearing plate 130 and facilitates subsequent maintenance and replacement work. When the liquid cooling plate 210 needs to be repaired or upgraded, the liquid cooling plate 210 can be easily removed from the cabinet 100 by simply removing the bolts between the positioning frame 220 and the load-bearing plate 130.

[0027] Both the return pipe 292 and the return pipe 293 are provided with an outer frame 290. The front and back of the outer frame 290 are provided with heat dissipation windows 291 at positions corresponding to the lateral part of the return pipe 292, and a filter screen is fixed inside the heat dissipation window 291. The outer wall of the return tube 292 is fitted with heat dissipation fins 294 in the transverse part, and the heat dissipation fins 294 are equidistantly distributed along the axial direction of the return tube 292.

[0028] The outer frame 290 not only provides additional protection for the return tube 292 and the return tube 293 to prevent them from being directly impacted by the external environment, but also accelerates the air circulation around the return tube 292 through the heat dissipation window 291 and the cooling fan 150 working together. In conjunction with the heat dissipation fins, it can improve the heat dissipation effect of the internal liquid, so that it can achieve better heat dissipation when it re-enters the liquid cooling plate 210. The installation of filters effectively prevents dust and impurities from entering the pipes, ensuring the cleanliness of the coolant and extending the service life of the entire cooling system.

The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
