Description

Technical Field

[0001] This utility model relates to the field of coolers, specifically a cooler cooling tube sheet with high heat exchange efficiency. Background Technology

[0002] In industrial production and equipment operation, the efficient heat exchange of coolers is of great significance for ensuring the stable operation of the system and improving production efficiency. At the same time, it can also effectively reduce the energy consumption of equipment and reduce energy waste, thereby realizing a greener and more economical production method. As the core component of the cooler, the cooling tube sheet undertakes the key heat exchange task. Its excellent heat exchange performance not only directly affects the overall thermal efficiency of the cooler, but also relates to the operational stability and reliability of the entire system.

[0003] Traditional cooler tube sheets mainly rely on a single cooling method, such as simple air cooling or water cooling. In air cooling mode, the air flow path is simple and the disturbance is insufficient, which easily forms a laminar boundary layer on the tube sheet surface, making it difficult for heat to be effectively dissipated. Although the overall heat transfer efficiency of water cooling mode is relatively high, the water flow channel design is unreasonable, resulting in uneven water flow distribution and low local heat exchange efficiency. In addition, some cooling tube sheets simply superimpose air cooling and water cooling functions without fully considering the synergistic effect of the two cooling methods. This not only occupies a lot of space, but also has defects such as complex structure, high manufacturing cost, and difficult maintenance. Therefore, we propose a cooler tube sheet with high heat exchange efficiency. Utility Model Content

[0042] Air duct frame 3: Hollow frame, square ring-shaped, fitted on the outside of cooling plate 2, with the inner ring fitting into cooling plate 2, used to guide the heat dissipation airflow in an orderly manner inside;

[0043] Mounting pipe 4: A tubular structure that runs through and connects to the air duct frame 3 at a set of diagonal positions corresponding to the inlet and outlet of the cooling pipe 1. One end is fixed to the air duct frame 3, and a cooling fan 5 is installed inside, serving to install and fix the fan and guide airflow into the air duct frame 3;

[0044] Cooling fan 5: A fan-blade structure installed inside the mounting tube 4, which generates airflow by rotating to provide power for air cooling.

[0045] Ventilation hole 6: It is opened on the side of the cooling plate 2 corresponding to the water inlet and outlet of the cooling pipe 1, located between the cooling pipe 1, and is hole-shaped, extending through to the heat dissipation hole 7, connecting the heat dissipation hole 7 with the outside, and quickly dissipating the heat of the cooling pipe 1.

[0046] Heat dissipation holes 7: Multiple holes are distributed on the four sides of the cooling plate 2, arranged in a grid pattern, with a hole structure that extends through the cooling pipe 1 and connects with the strip holes 8, so as to evenly guide the airflow in the air duct frame 3 to the outside of the cooling pipe 1.

[0047] Strip-shaped hole 8: Long strip-shaped hole, opened on the four sides of the air duct frame 3 and the cooling plate 2, used to connect the air duct frame 3 and the cooling plate 2, so that the airflow can enter the heat dissipation hole 7 of the cooling plate 2.

[0048] Water tank 9: Box-shaped structure, one side is fixedly connected to the side of cooling plate 2 that is away from the inlet and outlet of cooling pipe 1, used to hold cold water and absorb the heat of cooling pipe 1 and cooling plate 2.

[0049] Water inlet pipe 10: tubular structure, one end is connected to water tank 9 and guide plate 14 and the other side is open, the open end is fixed to the outside of water tank 9, used to introduce cold water into water tank 9;

[0050] Heat dissipation groove 11: It is formed on the side where the water tank 9 and the cooling plate 2 are connected. It is groove-shaped and evenly distributed to increase the contact area between the water tank 9 and the cooling plate 2 and improve the heat exchange efficiency.

[0051] Water outlet pipe 12: tubular structure, connected to water tank 9 and guide plate 13 on one side, with the open end fixed to the outside of water tank 9, and water pump 15 installed at the outer end to draw out the heat-exchanged water;

[0052] Flow guide plate 13: Plate-shaped structure, multiple plates are fixed at equal intervals along a straight line on one side wall of water tank 9, and are distributed at intervals with flow guide plate 2 14, used to guide the direction of cold water in water tank 9;

[0053] Flow deflector 2 14: Plate-shaped structure, multiple of which are fixed at equal intervals along a straight line on the side wall of water tank 9 opposite to flow deflector 13, and are distributed at intervals with flow deflector 13 to guide the flow of cold water in conjunction with flow deflector 13;

[0054] Water pump 15: Installed at one end of the outlet pipe 12 outside the water tank 9, used to draw water out of the water tank 9 and promote the circulation of cold water in the water tank 9.

[0055] Working principle: After the cooling fan 5 starts, it generates a strong airflow in the mounting pipe 4. The airflow enters the air duct frame 3, which acts as a guiding structure to ensure orderly airflow within the frame. The strip holes 8 on the four sides of the air duct frame 3 connect to the cooling plate 2. The grid-like heat dissipation holes 7 distributed on the four sides of the cooling plate 2 penetrate to the cooling pipe 1 and connect to the strip holes 8. The airflow enters the heat dissipation holes 7 through the strip holes 8 and is evenly guided to the outside of the cooling pipe 1. The ventilation holes 6 between the cooling pipes 1 penetrate to the heat dissipation holes 7 and connect to the outside, allowing the airflow to quickly remove heat from the surface of the cooling pipe 1 and discharge it through the ventilation holes 6. During this process, the staggered design of the heat dissipation holes 7 and ventilation holes 6 increases the contact area and turbulence between the air and the cooling pipe 1, disrupts the air boundary layer, and enhances convective heat transfer. The water pump 15 starts and introduces cold water into the water tank 9 through the water inlet pipe 10. Inside the water tank 9, guide plates 13 and 14 are spaced apart to guide the cold water to flow along a specific path, extending the residence time of the cold water in the water tank and allowing it to fully contact the cooling plate 2. The heat dissipation grooves 11 on the connection surface between the water tank 9 and the cooling plate 2 increase the contact area between the two and improve the heat exchange efficiency. After the cold water absorbs the heat transferred by the cooling plate 2 and the embedded cooling pipe 1, its temperature rises and it is discharged from the outlet pipe 12. Through the continuous circulation of cold water, the heat of the cooling plate is continuously carried away, achieving efficient water cooling. The two cooling methods, air cooling and water cooling, dissipate heat from different directions and parts of the cooling plate. Air cooling mainly targets the outside of the cooling pipe 1 and the area around the cooling plate 2 to quickly reduce the surface temperature, while water cooling absorbs deep heat from the back of the cooling plate 2. The two work together to form a three-dimensional heat dissipation system.
