Description

Technical Field

[0001] This utility model relates to the field of server supporting technology, specifically a waste heat recovery device for a liquid-cooled server. Background Technology

[0002] Liquid-cooled servers are servers in which liquid is injected into the server to remove heat through heat exchange. From a physical perspective, they can be categorized into: cold-plate liquid-cooled servers and fully immersion liquid-cooled servers. Cold-plate liquid cooling technology uses a working fluid as an intermediate heat transfer medium to transfer heat from the hot zone to a distant location for cooling. In this technology, the working fluid is separate from the object being cooled, and the working fluid does not directly contact the electronic components. Immersion phase-change liquid-cooled servers, in which the server motherboard, CPU, memory, and other heat-generating components are completely immersed in the refrigerant, are liquid-cooled. During operation, these heat-generating components generate heat, causing the refrigerant temperature to rise.

[0003] An investigation revealed that a Chinese utility model patent discloses a server cooling waste heat recovery device (publication number: CN218937104U), comprising a server body, a cooling component, and a heat exchange mechanism. The cooling end of the cooling component extends to the server body installation position, and the drain end of the cooling component is connected to a cooling tower via the heat exchange mechanism. The heat exchange mechanism includes a connecting pipe, a bend, a drain pipe, a heat exchange chamber, a partition, a through hole, a water injection pipe, a drain pipe, a valve, and a heat exchange box. The drain end of the cooling component is connected to the bend via the connecting pipe, and a drain pipe connected to the cooling tower is installed at the end of the connecting pipe. The heat energy of the continuously circulating water passes through the bend to heat-treat the water inside the heat exchange chamber, increasing the water temperature and realizing the utilization of waste heat. At the same time, the water inside the heat exchange chamber can also pre-cool the circulating water inside the bend, reducing subsequent cooling time. The heated hot water can be used at any time, reducing energy consumption and improving the heat energy recovery and utilization rate of the server cooling component.

[0004] Although the aforementioned patent uses a structure such as a water injection pipe to inject cold water into the heat exchange box, and the cold water circulates inside the heat exchange chamber with a bend passing through it, allowing the heat energy of the continuously circulating water to heat the water inside the heat exchange chamber through the bend and increase the water temperature to utilize waste heat, the temperature absorbed by the water is relatively fixed when heating the water through the bend to recover the heat generated by the liquid-cooled server. When there is a lot of heat, the water may evaporate, making it impossible to replace or store the water, thus wasting both heat and water.

[0005] Therefore, this utility model provides a waste heat recovery device for a liquid-cooled server to solve the above problems. Utility Model Content

[0010] The heat storage mechanism includes a water collection tank fixedly connected to one edge of the upper surface of the mounting base plate.

A water inlet pipe is fixedly connected to the upper surface of the water collection tank.

[0011] The waste heat recovery mechanism includes a recovery box fixedly connected to one side of the upper surface of the mounting base plate, and the waste heat utilization mechanism is installed on one side of the recovery box and the water collection tank.

[0012] As a preferred technical solution of this application, the waste heat recovery mechanism further includes a circulation pump fixedly connected inside the recovery box. The input end of the circulation pump is fixedly connected to a connecting pipe, which corresponds to the server cabinet. The output end of the circulation pump is fixedly connected to a circulation pipe.

[0013] As a preferred technical solution of this application, the waste heat recovery mechanism further includes a heat exchange box fixedly connected to one end of the circulation pipe. A cooling pipe is fixedly connected to the surface of the heat exchange box, and the cooling pipe corresponds to the server cabinet. A suspension plate corresponding to the heat exchange box is slidably connected to the surface of the heat exchange box, and the suspension plate is slidably connected to the inside of the recovery box.

[0014] As a preferred technical solution of this application, a water inlet groove is provided on one side of the heat exchange box, the water inlet groove is corresponding to the drain groove, a heat insulation plate corresponding to the heat exchange box is fixedly connected to the lower surface of the suspension plate, and a support spring corresponding to the suspension plate is fixedly connected to the inner bottom wall of the recovery box in a rectangular array.

[0017] (III) Beneficial Effects

[0018] By incorporating waste heat recovery, heat storage, and waste heat utilization mechanisms, and through a circulating pump, the cooled liquid, after absorbing heat, enters the heat exchange tank through a circulation pipe. The heat exchange tank heats the water inside the recovery tank, recovering the waste heat. When the heat exchange tank absorbs too much heat, a valve connects the recovery tank to the collection tank. Through the cooperation of the inlet and outlet channels, the buoyancy of the hot water pushes the floating plate upward, which in turn moves the sealing plate via a push rod. This allows the cold water in the collection tank to flow into the recovery tank through the outlet and inlet channels, recovering the heat again. Simultaneously, the heated water is preserved, preventing water evaporation and heat waste.

[0019] By incorporating waste heat recovery mechanisms and other structural elements, heat is recovered and the water is heated. The faucet and connecting pipe facilitate the use of the heated water by staff, thereby improving resource utilization. Furthermore, the support springs provide sufficient space inside the recycling bin, making it easier to add water and preventing the suspension plate from sticking to the bottom wall of the recycling bin, which would hinder the addition of water.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This utility model provides a waste heat recovery device for a liquid-cooled server, such as... Figures 1-5 As shown, the waste heat recovery device for the liquid-cooled server includes a mounting base plate 1 and a server cabinet 2 fixedly connected to the upper surface of the mounting base plate 1. The upper surface of the server cabinet 2 is fixedly connected with heat dissipation holes. A waste heat recovery mechanism is installed on one side of the upper surface of the mounting base plate 1. The waste heat recovery mechanism includes a recovery tank 8 fixedly connected to one side of the upper surface of the mounting base plate 1, and a circulation pump 10 fixedly connected inside the recovery tank 8. A connecting pipe 11 is fixedly connected to the input end of the circulation pump 10, corresponding to the server cabinet 2. The output end of the circulation pump 10 is fixedly connected to... The waste heat recovery mechanism also includes a heat exchange box 13 fixedly connected to one end of the circulation pipe 12. A water inlet 16 is provided on one side of the heat exchange box 13, and a cooling pipe 14 is fixedly connected to the surface of the heat exchange box 13. Through the cooperation of the circulation pump 10, the connecting pipe 11, the circulation pipe 12 and the cooling pipe 14, the heat inside the server cabinet 2 can be effectively absorbed. Under normal operating conditions of the server, this device can reduce the temperature inside the server cabinet 2. Compared with traditional heat dissipation methods, this device can improve energy utilization while ensuring heat dissipation effect and effectively reduce operating costs.

[0029] Cooling pipe 14 corresponds to server cabinet 2. A floating plate 15 corresponding to heat exchange box 13 is slidably connected to the surface of heat exchange box 13. A heat insulation plate corresponding to heat exchange box 13 is fixedly connected to the lower surface of floating plate 15. Through the setting of floating plate 15, the water inside recovery box 8 makes floating plate 15 float on top of recovery box 8, so that the water can completely wrap around heat exchange box 13, improving the efficiency of waste heat recovery.

[0030] The inner bottom wall of the recycling box 8 is fixedly connected with a rectangular array of support springs 17 corresponding to the suspension plate 15. The suspension plate 15 is slidably connected to the inside of the recycling box 8. When the coolant inside the connecting pipe 11 absorbs the heat inside the server cabinet 2, the coolant enters the heat exchange box 13 through the setting of the circulation pump 10, so that the heat exchange box 13 absorbs the heat in the coolant and heats the water inside the recycling box 8, thereby achieving the purpose of waste heat recovery.

[0031] Specifically, the heat exchanger 13 absorbs heat from the coolant, lowering its temperature, while simultaneously heating the water inside the recovery tank 8, thus achieving waste heat recovery. Compared to similar devices without the suspension plate 15 and support spring 17, this device can recover more waste heat in the same amount of time, effectively improving energy utilization efficiency.

[0032] A heat storage mechanism is installed on the upper surface of the mounting base plate 1 near the waste heat recovery mechanism. The heat storage mechanism includes a water collection tank 3 fixedly connected to one edge of the upper surface of the mounting base plate 1. Both the recovery tank 8 and the water collection tank 3 have observation slots on their surfaces. A waste heat utilization mechanism is installed on one side of the recovery tank 8 and the water collection tank 3. The waste heat utilization mechanism includes a connecting pipe 18 fixedly connected to one side of the recovery tank 8 and the water collection tank 3. A support plate 21 fixedly connected to the mounting base plate 1 is fixedly sleeved on the surface of the connecting pipe 18. A valve 19 is provided on the surface of the connecting pipe 18. When the heat exchange box 13 absorbs too much heat, causing the water to reach a certain temperature and unable to absorb and recover the heat, the valve 19 is turned to connect the recovery tank 8 and the water collection tank 3 through the connecting pipe 18, allowing the hot water inside the recovery tank 8 to enter the interior of the water collection tank 3 through the connecting pipe 18.

[0033] A faucet 20 is fixedly connected to the surface of the connecting pipe 18. The two ends of the connecting pipe 18 are connected to the recovery tank 8 and the water collection tank 3, respectively. A float plate 4 is slidably connected inside the water collection tank 3. A sealing plate 5 is slidably connected inside the water collection tank 3. Push rods 6 are fixedly connected to both sides of the lower surface of the sealing plate 5. The push rods 6 correspond to the float plate 4. A drain groove 7 is opened on one side of the water collection tank 3. The buoyancy of the hot water causes the float plate 4 to move upward, causing the push rods 6 to drive the sealing plate 5 to slide inside the water collection tank 3. The water collection tank 3 is connected to the recovery tank 8 through the cooperation of the drain groove 7 and the inlet groove 16, so that the cold water inside the water collection tank 3 enters the interior of the recovery tank 8 to recover the heat absorbed by the heat exchange box 13, thereby avoiding the waste of heat due to excessive heat. The inlet groove 16 corresponds to the drain groove 7, and the sealing plate 5 corresponds to the drain groove 7. A water inlet pipe 9 is fixedly connected to the upper surface of the water collection tank 3.

[0034] Specifically, when the waste heat recovery device of this liquid-cooled server is in use: through the cooperation of the circulation pump 10, connecting pipe 11, circulation pipe 12 and cooling pipe 14, the heat inside the server cabinet 2 is absorbed to achieve heat dissipation of the server cabinet 2. After the coolant inside the connecting pipe 11 absorbs the heat inside the server cabinet 2, the coolant enters the heat exchange box 13 through the setting of the circulation pump 10, so that the heat exchange box 13 absorbs the heat in the coolant and heats the water inside the recovery box 8, thereby achieving the purpose of waste heat recovery.

[0035] When the heat exchanger 13 absorbs too much heat, causing the water to reach a certain temperature and making it impossible to absorb and recover the heat, the valve 19 is turned to connect the recovery tank 8 and the water collection tank 3 through the connecting pipe 18. This allows the hot water inside the recovery tank 8 to enter the water collection tank 3 through the connecting pipe 18. The buoyancy of the hot water causes the float plate 4 to move upward, which in turn causes the push rod 6 to drive the sealing plate 5 to slide inside the water collection tank 3. This allows the water collection tank 3 to connect with the recovery tank 8 through the cooperation of the drain trough 7 and the inlet trough 16. This allows the cold water inside the water collection tank 3 to enter the recovery tank 8, recovering the heat absorbed by the heat exchanger 13 and thus avoiding the waste of heat due to excessive heat.

[0036] With the suspension plate 15 in place, the water inside the recovery tank 8 causes the suspension plate 15 to float on top of the recovery tank 8, so that the water can completely surround the heat exchange box 13, improving the efficiency of waste heat recovery. When hot water enters the water collection tank 3 and cold water enters the recovery tank 8, the cold water pushes the suspension plate 15 downward, so that the heat exchange box 13 is surrounded by cold water, avoiding affecting the efficiency of waste heat recovery of the heat exchange box 13 when the water is replaced.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
