Description

Technical Field

[0001] This utility model relates to the field of radiator technology, and more specifically, to an energy-saving plate-fin radiator. Background Technology

[0002] Plate-fin radiators are highly efficient heat dissipation devices commonly used in industrial and automotive applications. Their design is based on the principles of heat exchange and gas fluid dynamics. The plate-fin structure provides a large heat exchange surface for rapid and efficient heat transfer. Plate-fin radiators typically consist of a series of parallel-arranged heat dissipation fins. Numerous tiny channels are formed between these metal plates and fins for fluid flow. Heat is transferred through convection and conduction between the surface of the plate-fin structure and the fluid within the channels.

[0003] Most existing plate-fin radiators are in an open state. After long-term use, dust easily accumulates on the surface, affecting the heat dissipation efficiency of the plate fins. They are also difficult to clean, increasing the energy consumption of the plate-fin radiator. Utility Model Content

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. Because the heat dissipation fins are curved, the water flow residence time is increased, and the heat exchange area of ​​the heat dissipation fins is also increased. By setting heat exchange components, the water heat exchange fins are parallel to the direction of water flow, and the air heat exchange fins are parallel to the direction of air flow, so as to avoid affecting the flow of water and air.

[0022] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0023] As attached Figure 1 To be continued Figure 4 As shown, an embodiment of this utility model provides an energy-saving plate-fin radiator, including a fixed outer shell 1, a radiator body 2 fixedly installed inside the fixed outer shell 1, and a ventilation device 3 fixedly installed on the side of the fixed outer shell 1.

[0024] like Figures 2-3 As shown, the radiator body 2 includes an upper connecting water pipe 21 and a lower connecting water pipe 22. Multiple heat dissipation fins 26 are fixedly installed between the upper connecting water pipe 21 and the lower connecting water pipe 22. An inlet pipe 23 is fixedly connected to the right side of the top of the upper connecting water pipe 21, and an outlet pipe 24 is fixedly connected to the left side of the bottom of the lower connecting water pipe 22. Multiple connecting grooves 25 are opened inside the upper connecting water pipe 21 and the lower connecting water pipe 22. The multiple heat dissipation fins 26 are connected through the connecting grooves 25. The heat dissipation fins 26 are curved, and heat exchange components 27 are fixedly connected to both the upper and lower ends of the curved part of the heat dissipation fins 26. Because the heat dissipation fins 26 are curved, the water flow residence time is increased. At the same time, the heat exchange area of ​​the heat dissipation fins 26 is increased, thereby improving the heat dissipation effect of the heat dissipation fins 26.

[0025] like Figure 4As shown, the heat exchange assembly 27 includes a heat exchange plate 271, with a wind heat exchange fin 273 fixedly installed at the bottom of the heat exchange plate 271 and a water heat exchange fin 272 fixedly installed at the top of the heat exchange plate 271. The heat exchange plate 271 is fixedly installed on the side of the heat dissipation fin 26, with the wind heat exchange fin 273 located on the outside of the heat dissipation fin 26 and the water heat exchange fin 272 located in the inner cavity of the heat dissipation fin 26.

[0026] By setting the heat exchange component 27, the water heat exchange fins 272 are parallel to the direction of water flow, while the air heat exchange fins 273 are parallel to the direction of air flow, thus avoiding affecting the flow of water and air. At the same time, it increases the contact area with water and air flow, thereby improving the heat dissipation effect of the radiator.

[0027] like Figure 5 As shown, the fixed housing 1 includes a housing plate 11. A fixed plate 12 is fixedly installed on the right side of the housing plate 11. Limiting rods 13 are fixedly installed on both sides inside the fixed plate 12. A lifting frame 14 is movably sleeved on the outer surface of the limiting rods 13. A fixed rack 15 is fixedly installed on one side of the lifting frame 14. A lifting motor 16 is fixedly installed on the top of the fixed plate 12. A rotating screw 17 is fixedly installed on the output end of the lifting motor 16. The rotating screw 17 is rotatably installed inside the fixed plate 12. One end of the lifting frame 14 is threadedly connected to one end of the rotating screw 17.

[0028] Multiple rotating shafts 18 are rotatably mounted on the side of the outer shell plate 11. A transmission gear 19 is fixedly sleeved at one end of the rotating shaft 18. The outer surface of the transmission gear 19 meshes with the side of the fixed rack 15. A side plate 110 is fixedly sleeved on the outer surface of the rotating shaft 18. The side plate 110 is rotatably mounted inside the outer shell plate 11. When the radiator stops working, the lifting motor 16 controls the rotating screw 17 to rotate, causing the lifting frame 14 to rise and fall. By utilizing the transmission between the fixed rack 15 and the transmission gear 19, the side plate 110 rotates to a state perpendicular to the airflow, and the radiator is in a relatively closed state, preventing dust from falling inside the radiator body 2 and affecting the service life of the radiator body 2.

[0029] like Figure 6As shown, the ventilation device 3 includes a back plate 31, which is fixedly installed on the side of the outer shell plate 11. Both sides of the back plate 31 are fixedly connected to ventilation openings 32. Multiple mounting blocks 34 are fixedly installed on the outer surface of the ventilation openings 32. A ventilation fan 33 is fixedly installed inside the ventilation openings 32. A filter screen 35 is detachably installed on the side of the ventilation openings 32. Multiple fixing blocks 36 corresponding to the mounting blocks 34 are fixedly installed on the outer surface of the filter screen 35. The fixing blocks 36 are fixedly connected to the mounting blocks 34 by bolts. The filter screen 35 filters the air entering the radiator body 2, preventing dust from accumulating inside the heat dissipation fins 26, which would reduce the heat exchange efficiency of the heat dissipation fins 26 and thus increase energy consumption. At the same time, the filter screen 35 can be disassembled for easy cleaning.

[0030] The working process of this utility model is as follows:

[0031] In use, the lifting motor 16 controls the rotating screw 17 to rotate, causing the lifting frame 14 to rise. The fixed rack 15 drives the transmission gear 19 to rotate, causing the side plate 110 to rotate. The side plate 110 rotates to a state parallel to the airflow direction. Hot water enters through the inlet pipe 23, enters the interior of the heat dissipation fins 26 through the connecting groove 25, and is discharged through the outlet pipe 24. During the heat dissipation process of the hot water inside the heat dissipation fins 26, the air heat exchange fins 273 are located on the outside of the heat dissipation fins 26, and the water heat exchange fins 272 are located in the inner cavity of the heat dissipation fins 26. The water heat exchange fins 272 are parallel to the water flow direction, while the air heat exchange fins 273 are parallel to the airflow direction, increasing the contact area with water and airflow. At the same time, the ventilation fan 33 works, causing the airflow to pass through the interior of the ventilation port 32 and be discharged from the radiator body 2, improving the heat exchange efficiency between the airflow and water, thereby improving the heat dissipation effect of the radiator body 2 and reducing the energy consumption of the radiator.

[0032] After use, the lifting motor 16 controls the rotating screw 17 to rotate in the opposite direction, the lifting frame 14 descends, and pushes the transmission gear 19 to rotate in the opposite direction, so that the side plate 110 rotates to be perpendicular to the airflow, so that the radiator body 2 is in a relatively closed state, preventing dust from falling into the inside of the radiator body 2 and affecting the service life of the radiator.
