Description

Technical Field

[0001] The invention relates to the technical field of water refrigeration units, in particular to a low-noise liquid cooling device for accelerating air circulation. Background Art

[0002] A water-cooled chiller is a refrigeration system that uses water or aqueous solution as a cooling medium. It is mainly composed of core components such as a compressor, a condenser, an evaporator, and an expansion valve. Its working principle is to compress the gaseous refrigerant into a high-temperature and high-pressure state through the compressor and send it into the condenser. The refrigerant in the condenser is cooled by water or air to liquefy it. The liquid refrigerant enters the evaporator after throttling and reducing the pressure through the expansion valve to absorb heat for refrigeration, and finally returns to the compressor to complete the cycle. Water-cooled chillers are widely used in central air conditioning, industrial cooling, refrigeration and other fields. They have the characteristics of high refrigeration efficiency, stable operation, and suitability for large cooling capacity requirements. The heat dissipation efficiency of the condenser directly affects the overall performance of the unit. Therefore, optimizing the heat dissipation design of the condenser is the key to improving the energy efficiency and reliability of water-cooled chillers. In the prior art, the condenser of a water-based refrigeration unit usually relies on natural convection or simple forced air cooling to dissipate heat. However, due to the complexity of the condenser structure, especially for cylindrical or coil-type condensers, the rear area often has low heat dissipation efficiency due to uneven airflow distribution. Traditional heat dissipation designs mostly use direct blowing or large-area fans to supply air, which makes it difficult for the airflow to evenly cover the entire surface of the condenser. In particular, the problem of uneven heat dissipation on the front and rear sides is prominent, resulting in local overheating of the condenser, affecting the effective condensation of the refrigerant, and thereby reducing the cooling efficiency and operating stability of the entire unit. In addition, existing heat dissipation structures often fail to fully consider the overall shape matching of the condenser, making it impossible for the airflow to be accurately directed to the key heat dissipation area, resulting in the dual problems of energy waste and insufficient heat dissipation. Therefore, there is an urgent need for an innovative design that can optimize airflow distribution and improve the overall heat dissipation efficiency of the condenser to ensure efficient and stable operation of the water-based refrigeration unit. Summary of the invention

[0003] (1) Technical problem to be solved: Aiming at the deficiencies of the prior art, the present invention provides a low-noise liquid-cooling temperature reduction device for accelerating air circulation. Through the designed heat dissipation plate and air outlet holes, the present invention can accelerate the air circulation on the surface of the condenser at the rear of the water refrigeration unit, effectively reducing the temperature generated during the operation of the condenser. The condenser is a key component in the water refrigeration unit, and its main function is to condense the gaseous refrigerant, which is compressed and heated in the compressor, into a liquid state while releasing heat. The shape of the heat dissipation plate matches the overall rear shape of the condenser. Combining with the air outlet angle of the air outlet holes, when dissipating heat from the rear surface of the cylindrical condenser, the air can evenly contact the front surface of the condenser, effectively improving the heat dissipation efficiency of the condenser, ensuring that the heat on the surface of the condenser is quickly removed, preventing overheating, and maintaining the normal operation of the refrigeration system, which helps to improve the performance and reliability of the entire water refrigeration unit.

[0004] (2) Technical solution: To solve the above technical problem, the present invention provides the following technical solution: A low-noise liquid-cooling temperature reduction device for accelerating air circulation, including a base, on the top of which a water refrigeration unit is arranged, and a condenser is arranged on the lower side at the rear of the water refrigeration unit. In the middle of the rear end face of the base, a mounting plate is fixedly connected by bolts, and a vertical plate is fixedly connected to the top end at the rear of the mounting plate.

[0005] Preferably, a fixed bottom plate is fixedly connected to the middle of the lower part of the rear end face of the vertical plate, a high-pressure blower is fixedly connected to the top of the fixed bottom plate, a connecting flange is fixedly connected to the output end of the high-pressure blower, an air inlet pipe is fixedly connected to the front end face of the connecting flange, air outlets are opened in the air inlet pipe and the connecting flange, an external thread structure is arranged on the outer side of the air inlet pipe, an internal thread structure is arranged in the middle of the vertical plate, a groove is opened on the front end face of the vertical plate, a heat dissipation plate is fixedly connected to the groove on the front end face of the vertical plate, an air duct is opened in the heat dissipation plate, a sealing ring is fixedly connected to the middle of the rear end face of the heat dissipation plate, air outlet holes are opened on the front end face of the heat dissipation plate, the internal thread structure in the middle of the vertical plate is spirally engaged with the external thread structure, and the inner side of the sealing ring in the middle of the rear end face of the heat dissipation plate contacts the front surface of the air inlet pipe, which can accelerate the air circulation on the surface of the condenser at the rear of the water refrigeration unit, effectively reducing the temperature generated during the operation of the condenser, effectively improving the heat dissipation efficiency of the condenser, ensuring that the heat on the surface of the condenser is quickly removed, preventing overheating, and maintaining the normal operation of the refrigeration system, which helps to improve the performance and reliability of the entire water refrigeration unit.

[0006] Preferably, the condenser is cylindrical in shape, and the number of condensers is three. The condensers are distributed vertically at the lower rear position of the water cooling unit. The inner shape of the heat dissipation plate matches the overall rear shape of the three condensers, and the shape of the heat dissipation plate matches the overall rear shape of the condensers. When combined with the air outlet angle of the air outlet holes, when dissipating heat from the rear surface of the cylindrical condenser, the wind can evenly contact the front surface of the condenser as well.

[0007] Preferably, the number of air outlet holes on the front end face of the heat dissipation plate is several, and the air outlet holes are horizontally arranged on the front end face of the heat dissipation plate and are evenly distributed vertically from top to bottom. The front end face of the heat dissipation plate has a semi-circular arc extending backward, and each semi-circular arc extending backward on the front end face of the heat dissipation plate is provided with 3 sets of vertical columns of air outlet holes. The blown air can be evenly distributed on the surface of the condenser, effectively improving the heat dissipation efficiency of the condenser, ensuring that the heat on the surface of the condenser can be quickly taken away, and preventing overheating.

[0008] Preferably, a through hole is opened in the middle of the rear part inside the heat dissipation plate, and the diameter of the through hole matches the outer diameter of the sealing ring. The air ducts opened inside the heat dissipation plate communicate with the air outlet holes on the front end face of the heat dissipation plate and the through hole on the rear end face of the heat dissipation plate. The setting of the sealing ring can increase the sealing performance between the vertical plate and the air inlet pipe, preventing the air blown by the high-pressure blower from passing through the gap between the vertical plate and the air inlet pipe.

[0009] Preferably, a through hole extending from front to back is opened in the middle of the upper part inside the vertical plate, and an internal thread structure is provided on the inner wall of the through hole. The front-to-back length of the internal thread structure is the same as the front-to-back length of the external thread structure, allowing the air inlet pipe to be detached from the vertical plate for cleaning the air inlet pipe.

[0010] Preferably, the shape of the groove on the front end face of the vertical plate matches the shape of the rear end face of the heat dissipation plate. The number of mounting plates is 2, and the gap between the mounting plates matches the thickness of the base, allowing the vertical plate to be fixed to the rear end face of the base and enabling installation according to water cooling units in different states.

[0011] Preferably, a one-way air guide plate is fixedly connected to the inner wall of the air inlet of the air inlet pipe, and the one-way air guide plates are distributed on the upper and lower sides of the inner wall of the air inlet of the air inlet pipe. The total number of one-way air guide plates is odd, the number of one-way air guide plates on the upper side of the inner wall of the air inlet pipe is even, and the number of one-way air guide plates on the lower side of the inner wall of the air inlet pipe is odd. When the high-pressure blower continuously outputs high-pressure air into the heat dissipation plate, it can effectively prevent some of the air from flowing back due to being blocked by the narrow air ducts opened inside the heat dissipation plate.

[0012] Preferably, the longitudinal section of the one-way air deflector is J-shaped, and the curved end of the one-way air deflector is arranged at the rear position of the air outlet pipe. The one-way air deflector as a whole has an inclination angle, and the inclination angle of the one-way air deflector is 15° inclined from the middle of the rear to the outside of the front. The one-way air deflector in the air inlet pipe has an asymmetric flow channel design. When the air flow flows from the high-pressure blower to the heat dissipation plate, the path is relatively smooth and the resistance is small; when the air flow tries to flow in the reverse direction, it will encounter more turbulence and resistance, thus hindering the flow.

[0013] Compared with the prior art, the present invention provides a low-noise liquid cooling device for accelerating air circulation, having the following beneficial effects: 1. Compared with the prior art, through the designed heat dissipation plate and air outlet holes, the present invention can accelerate the air circulation on the surface of the condenser at the rear side of the water cooling unit, effectively reducing the temperature generated during the operation of the condenser. The condenser is a key component in the water cooling unit. Its main function is to condense the gaseous refrigerant that has been compressed and heated in the compressor into a liquid state while releasing heat. The shape of the heat dissipation plate matches the overall rear shape of the condenser. With the air outlet angle of the air outlet holes, when dissipating heat from the rear surface of the cylindrical condenser surface, the air can evenly contact the front surface of the condenser, effectively improving the heat dissipation efficiency of the condenser, ensuring that the heat on the condenser surface is quickly taken away, preventing overheating, and maintaining the normal operation of the refrigeration system, which helps to improve the performance and reliability of the entire water cooling unit.

[0014] 2. Compared with the prior art, through the designed air inlet pipe and one-way air deflector, when the high-pressure blower continuously outputs high-pressure air into the heat dissipation plate, the present invention can effectively prevent a part of the air from flowing back due to being blocked by the narrow air ducts opened in the heat dissipation plate. The one-way air deflector in the air inlet pipe has an asymmetric flow channel design. When the air flow flows from the high-pressure blower to the heat dissipation plate, the path is relatively smooth and the resistance is small; when the air flow tries to flow in the reverse direction, it will encounter more turbulence and resistance, thus hindering the flow. This design can suppress the air flow reflux in the air inlet pipe, forcing more air to be discharged from the air outlet end close to the heat dissipation plate, thereby maintaining a higher static pressure in the air inlet pipe and increasing the air pressure in the air inlet pipe to a certain extent.

[0030] Embodiment Two: Please refer to Figures 3 to 5 as shown: A one-way air guide plate 15 is welded to the inner wall of the air inlet 12 of the air inlet pipe 10.

[0034] Working principle: Before use, install the vertical plate 4 at the rear of the water chiller 2. Insert the mounting plate 8 at the front side of the bottom of the vertical plate 4 into the rear end face of the base 1 at the bottom of the water chiller 2. At this time, the heat dissipation plate 5 on the front end face of the vertical plate 4 is close to the rear end face of the condenser 3 located below the water chiller 2. Use bolts to connect and fix the mounting plate 8 to the top of the rear end of the base 1. Then take out the air inlet pipe 10 and insert the air inlet pipe 10 into the rear part inside the vertical plate 4 from front to back until the external thread structure 14 on the outside of the air inlet pipe 10 is screwed with the internal thread structure 18 in the middle of the vertical plate 4 at this time. Rotate the air inlet pipe 10. Under the mutual screwing action of the external thread structure 14 and the internal thread structure 18, the air inlet pipe 10 is butted against the rear of the air duct 13 inside the heat dissipation plate 5 from back to front. At this time, the outside of the front end of the air inlet pipe 10 is inserted into the inside of the sealing ring 16. After the air inlet pipe 10 is installed, take out the high-pressure fan 7, connect the output end of the high-pressure fan 7 to the connecting flange 11 at the rear end of the air inlet pipe 10 and fix it with bolts. Then use bolts to connect and fix the base 1 of the high-pressure fan 7 to the top of the fixed bottom plate 6, and the installation is completed; During use, turn on the water chiller 2 and the high-pressure fan 7 on the top of the fixed bottom plate 6. The condenser 3 generates heat during the operation of the water chiller 2, and the high-pressure fan 7 blows air into the air duct 13 inside the heat dissipation plate 5 through the air inlet pipe 10, and then blows it evenly onto the surface of the condenser 3 through the air outlet holes 9 provided on the front end face of the heat dissipation plate 5, effectively improving the heat dissipation efficiency of the condenser 3, ensuring that the heat on the surface of the condenser 3 is quickly taken away and preventing overheating. The inner wall of the air inlet 12 opened inside the air inlet pipe 10 is provided with a one-way air guide plate 15, and the one-way air guide plate 15 has an asymmetric flow channel design. When the air flow flows from the high-pressure fan 7 to the heat dissipation plate 5, the path is relatively smooth and the resistance is small; when the air flow tries to flow in the reverse direction, it will encounter more turbulence and resistance, thus hindering the flow. This design can suppress the air flow backflow in the air inlet pipe 10, making more air flow forced to be discharged from one end of the air inlet 12 close to the heat dissipation plate 5, so as to maintain a higher static pressure in the air inlet pipe 10 and increase the air pressure in the air inlet pipe 10 to a certain extent.
