Description

Technical Field

[0001] This invention relates to the field of liquid cooling source unit technology, and in particular to an integrated wide-temperature, high-precision closed-loop liquid cooling source unit. Background Technology

[0002] The integrated wide-temperature high-precision closed-loop liquid cooling unit is a closed-loop liquid cooling device that integrates refrigeration, heating, circulation, precision measurement and control and protection functions. It adopts a full-frequency variable compressor and water pump, PID intelligent control and high-precision temperature sensing technology. It can operate stably in a wide temperature range of -40℃ to +80℃, with high temperature control accuracy, rapid switching between hot and cold, low leakage, high reliability and remote monitoring capabilities. It is widely used in the precision thermal management of semiconductor equipment, laser processing, precision testing, energy storage batteries and high-end industrial equipment.

[0003] Existing liquid cooling units dissipate the heat from the high-temperature, high-pressure refrigerant discharged from the compressor into the environment through a cooling fan at the top. During the use of the cooling fan, regular cleaning and maintenance are required. However, since the existing cooling fan is located inside the heat dissipation vent at the top, it cannot be automatically removed for cleaning and maintenance. It can only be carried out manually, which is not only cumbersome, time-consuming, and labor-intensive, but also inefficient. Furthermore, improper disassembly and assembly can easily lead to equipment failure.

[0004] In summary, the existing technology lacks a technology that allows for removable maintenance when cleaning and maintaining the cooling fans of liquid-cooled units. Summary of the Invention

[0012] Preferably, the bottom end of the storage rack is fixedly connected to the top end of the liquid cooling source unit's outer shell. A U-shaped rack is slidably fitted on the inner wall of the top end of the storage rack. A plurality of springs are fixedly connected to one side of the U-shaped rack. The other end of each spring is fixedly connected to the inner wall of the top end of the storage rack. A sliding rod is fixedly connected to the other side of the U-shaped rack. The other end of the sliding rod extends through the inner wall of the top end of the storage rack to the outside. A trapezoidal plate is fixedly connected to the outer end of the sliding rod. The trapezoidal plate is slidably contacted with one side of the lifting ring frame.

[0013] Preferably, the sealing assembly includes a movable plate, the bottom end of which is slidably in contact with the top end of the heat dissipation pipe, the outer wall of which is adapted to the opening of the storage rack, and two push rod groups are rotatably connected to one side of the top end of the movable plate in a cross-symmetrical structure.

[0018] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0019] like Figures 1-10 The integrated wide-temperature, high-precision closed-loop liquid cooling source unit shown includes a liquid cooling source unit shell 1. Two heat dissipation pipes 2 are symmetrically connected to the top of the shell 1. A lifting ring frame 3 is fixedly installed at the top of the heat dissipation pipes 2. A cooling fan 4 is installed inside the lifting ring frame 3. A protective net 5 is installed at the top of the lifting ring frame 3. A locking component 6 is slidably fitted at one end of the lifting ring frame 3, and an adjustment component 7 is installed at the other end. A storage rack 8 is provided behind the heat dissipation pipes 2, and a sealing component 9 is installed inside the storage rack 8. Electric push rods 301 are fixedly connected to both ends of the lifting ring frame 3. The bottom end of the electric push rod 301 is fixedly connected to the top of the liquid cooling source unit shell 1. A sliding groove 302 is provided through the end of the lifting ring frame 3 near the locking component 6. An annular scraper ring 303 is fixedly connected to the end of the lifting ring frame 3 located inside the heat dissipation pipes 2. A groove is provided at the top of the annular scraper ring 303, and the outer wall of the annular scraper ring 303 is slidably fitted with the inner wall of the heat dissipation pipes 2.

[0020] This unit is equipped with a mature vapor compression refrigeration system. Through a closed-loop cycle principle—compressing the refrigerant with a compressor, exchanging heat in the condenser, reducing pressure with a throttling element, and absorbing heat in the evaporator—it continuously removes the heat generated by the controlled equipment, achieving precise system cooling. It can adapt to continuous cooling, intermittent cooling, and transient high heat flux density heat dissipation requirements under different operating conditions. It features fast cooling response, minimal temperature fluctuations, and can maintain a constant temperature operating environment for precision equipment throughout the entire process. In terms of energy-saving cooling, the unit relies on full-frequency adaptive regulation technology, which automatically matches the compressor frequency, pump speed, and fan power according to the load heat load, set temperature, and actual temperature difference. This eliminates the energy consumption drawbacks of traditional fixed-frequency equipment operating at full load continuously, significantly reducing unnecessary energy consumption under no-load and low-load conditions. Simultaneously, it incorporates high-efficiency heat exchange coils, a reinforced heat exchange structure, and a low-flow-resistance piping design, effectively improving heat exchange efficiency and reducing energy loss during heat exchange. Compared to traditional split-type temperature control equipment, the overall cooling energy efficiency ratio is significantly improved, demonstrating excellent energy-saving performance.

[0021] The annular scraper ring 303 automatically removes dust adhering to the inner wall of the heat dissipation pipe 2 when the lifting ring frame 3 moves upward.

[0022] By setting up the lifting ring 3, when the cooling fan 4 of the liquid cooling source unit needs to be cleaned and maintained, it can automatically move upward to move the cooling fan 4 out of the cooling pipe 2. At the same time, under the action of the adjustment component 7, it can automatically rotate and move the protective net 5 above the cooling fan 4 away. When cleaning and maintaining the cooling fan 4, there is no need for manual disassembly, which greatly simplifies the maintenance operation, improves the maintenance efficiency, avoids equipment failure caused by improper disassembly and assembly, and ensures the stability of the unit operation.

[0023] like Figure 4 As shown, a guide plate 201 is fixedly connected to the outer wall of the heat dissipation pipe 2 near the locking component 6. Both ends of the guide plate 201 are provided with inclined surfaces. A fixing rack 202 is fixedly connected to the upper outer wall of the end of the heat dissipation pipe 2 near the adjusting component 7.

[0024] The guide plate 201 enables the locking component 6 to automatically move open and unlock, and the fixed rack 202 enables the adjusting component 7 to automatically rotate the protective net 5 to open and close.

[0025] like Figure 5 As shown, a rubber pad 304 is fixedly connected to the bottom end of the lifting ring frame 3, and the rubber pad 304 abuts against the top end of the heat dissipation pipe 2.

[0026] The rubber pad 304 is made of high-elasticity and wear-resistant rubber material and is placed on the joint end face of the lifting ring 3 and the heat dissipation pipe 2. When the equipment is running normally, the rubber pad 304 fits tightly against the joint, which can effectively fill the joint gap, buffer the high-frequency vibration generated by the high-speed operation of the heat dissipation fan 4, block the vibration transmission, reduce the operating noise of the equipment, and improve the operating stability of the equipment.

[0027] like Figure 6 As shown, a locking hole 501 is provided on the outer wall of the protective net 5 near the locking component 6. A rotating end 502 is fixedly connected to the end of the protective net 5 near the adjusting component 7. The rotating end 502 is rotatably connected to the top of the lifting ring frame 3. A worm gear 503 is fixedly connected to the middle of the rotating end 502.

[0028] like Figure 7 As shown, the locking assembly 6 includes a sliding frame 601. The outer wall of the top of the sliding frame 601 is slidably engaged with the inner wall of the slide groove 302. A locking block 602 is fixedly connected to the top of the sliding frame 601. The outer wall of the other end of the locking block 602 is movably inserted into the locking hole 501. A spring 603 is fixedly connected to one side of the sliding frame 601. The other end of the spring 603 is fixedly connected to the inner wall of the slide groove 302. A contact wheel 604 is rotatably connected to the bottom of the sliding frame 601. The contact wheel 604 is slidably in contact with the outer wall of the guide plate 201.

[0029] Spring 603 enables the locking block 602 to automatically insert and lock.

[0030] like Figure 8 As shown, the adjustment assembly 7 includes a fixed frame 701. The top end of the fixed frame 701 is fixedly connected to the bottom end of the lifting ring frame 3. A universal joint 702 is rotatably connected through the bottom end of the fixed frame 701. An adjustment wheel 703 is fixedly connected to one end of the fixed frame 701. The adjustment wheel 703 is meshed with the fixed rack 202 for transmission. A worm 704 is fixedly connected to the other end of the universal joint 702. The top end of the worm 704 is rotatably connected through the lifting ring frame 3. The worm 704 is meshed with the worm wheel 503 for transmission.

[0031] The worm gear 704 and worm wheel 503 can precisely drive the protective net 5 to flip and open. At the same time, the self-locking characteristic ensures that the protective net 5 is fixed in position after opening and closing and will not shake at will, thus improving the structural stability.

[0032] like Figure 9As shown, the bottom of the storage rack 8 is fixedly connected to the top of the liquid cooling source unit shell 1. A U-shaped rack 801 is slidably fitted on the inner wall of the top of the storage rack 8. Multiple springs 802 are fixedly connected to one side of the U-shaped rack 801. The other end of the springs 802 is fixedly connected to the inner wall of the top of the storage rack 8. A sliding rod 803 is fixedly connected to the other side of the U-shaped rack 801. The other end of the sliding rod 803 extends through the inner wall of the top of the storage rack 8 to the outside. A trapezoidal plate 804 is fixedly connected to the outer end of the sliding rod 803. The trapezoidal plate 804 is slidably contacted with one side of the lifting ring frame 3.

[0033] Spring 802 enables the U-shaped rack 801 to automatically reset. Trapezoidal plate 804 pushes and maintains the moving position when the lifting ring 3 moves upward.

[0034] like Figure 10 As shown, the sealing assembly 9 includes a movable plate 901. The bottom end of the movable plate 901 is slidably in contact with the top end of the heat dissipation pipe 2. The outer wall of the movable plate 901 is adapted to the opening of the storage rack 8. Two push rod groups 902 are rotatably connected to one side of the top end of the movable plate 901 in a cross-symmetrical structure. The other end of the push rod group 902 is rotatably connected to the inner wall of the top end of the storage rack 8 through a pin. A gear 903 is fixedly connected to the top end of the pin. The gear 903 is meshed with the U-shaped rack 801 for transmission.

[0035] A sealing plastic sheet 904 is fixedly connected to one side of the bottom of the movable plate 901. A roller 905 is fixedly connected to the other end of the sealing plastic sheet 904. Both ends of the roller 905 are rotatably connected to the inner wall of the storage rack 8. A coil spring 906 is fixedly connected between both ends of the roller 905 and the inner wall of the storage rack 8.

[0036] The sealing plastic sheet is made of thin and lightweight material, has good dustproof effect, and can be rolled up for storage. When unfolded, it can completely cover the top opening of the heat dissipation pipe 2, preventing dust and debris from falling in.

[0037] Working principle: When the unit is running normally, the electric push rod 301 is in the retracted state, the lifting ring 3 moves down to reset, and the bottom rubber pad 304 is tightly abutted against the top of the heat dissipation pipe 2, which plays a role in buffering and vibration reduction, reducing the vibration and noise of the fan. At this time, the locking block 602 of the locking component 6 is inserted into the locking hole 501 of the protective net 5 under the action of the spring 603, and the protective net 5 is closed, locked, and fixed firmly. The sealing component 9 is completely retracted under the action of the disc spring 906 and the spring 802, and the sealing plastic cloth 904 is wound on the roller 905. The heat dissipation fan 4 runs normally and completes the forced convection heat dissipation of the unit through the heat dissipation pipe 2, ensuring the high-precision heat exchange requirements under wide temperature conditions.

[0038] When the cooling fan 4 needs cleaning and maintenance, the electric push rods 301 on both sides extend synchronously, pushing the lifting ring 3 to move vertically and smoothly upward. During the lifting process, the bottom contact wheel 604 of the locking component 6 slides along the inclined surface of the guide plate 201. The inclined surface squeezes the sliding frame 601 to slide, compressing the spring 603, causing the locking block 602 to exit the locking hole 501, automatically releasing the locking of the protective net 5. Then, the lifting ring 3 moves upward, causing the adjusting wheel 703 to roll along the fixed rack 202. Through the universal joint 702, the worm gear 704 is driven to rotate, meshing and driving the worm wheel 503 to rotate, causing the protective net 5 to automatically flip and open around the rotating end 502, completely exposing the maintenance and operation space above.

[0039] During the entire upward movement of the lifting ring 3, the annular scraper 303 on the inner side of the bottom edge slides along the inner wall of the heat dissipation pipe 2, automatically scraping away the accumulated dust and flocculent impurities attached to the inner wall of the pipe. The scraped dust is temporarily stored in the groove at the top of the annular scraper 303, realizing automated cleaning of the inner wall of the air duct. There is no need for manual cleaning of the air duct, ensuring smooth airflow and maintaining the unit's efficient heat dissipation performance.

[0040] After the annular scraper ring 303 is completely removed from the heat dissipation pipe 2, as the lifting ring frame 3 continues to move upward, the side wall squeezes the trapezoidal plate 804, pushing the sliding rod 803 to slide, causing the U-shaped rack 801 to slide and compress the second spring 802; the U-shaped rack 801 meshes and drives the gears 903 on both sides to rotate, causing the push rod assembly 902 to swing, pushing the moving plate 901 to move horizontally towards the top opening of the heat dissipation pipe 2; at the same time, the sealing plastic cloth 904 is stretched, so that the sealing plastic cloth 904 completely covers the top opening of the heat dissipation pipe 2, forming a dust barrier, which can effectively prevent dust generated during the fan cleaning process from falling into the pipe and the inside of the unit, ensuring the cleanliness of the inside of the unit in all aspects.

[0041] After the lifting ring 3 is fully raised, the staff can directly blow and wipe the fan blades and fan frame for cleaning. No parts need to be disassembled throughout the process. The operation is simple and efficient, and there is no risk of damage to the equipment due to disassembly.

[0042] After maintenance is completed, the electric actuator 301 retracts, causing the lifting ring 3 to move vertically downwards to reset. During the downward movement, the lifting ring 3 first disengages from the trapezoidal plate 804, and the second spring 802 rebounds, causing the U-shaped rack 801 to reset. With the help of the coil spring 906, the sealing plastic cloth 904 is automatically rolled up and stored, and the moving plate 901 resets. Then, the adjusting wheel 703 rolls in the opposite direction, causing the protective net 5 to close automatically. Then, the contact wheel 604 disengages from the guide plate 201, and the first spring 603 rebounds to reset, causing the locking block 602 to automatically insert into the locking hole 501, completing the automatic locking of the protective net 5. Finally, the rubber pad 304 at the bottom of the lifting ring 3 presses against the top of the heat dissipation pipe 2 to complete the reset.
