Description

Technical Field

[0001] This utility model relates to the field of metal processing, specifically to a heat dissipation device for die-cast radiators. Background Technology

[0002] Die-cast radiators are equipment components that are produced by casting. Generally, molten metal is poured into a mold cavity using a metal mold to obtain radiator parts of various shapes and sizes. During the production of die-cast parts, a heat dissipation device is needed to cool the formed die-cast parts in order to facilitate subsequent processing.

[0003] In the existing technology, air-cooling devices are mainly composed of main components such as motors and fan blades. When in use, the fan blades can be rotated by driving the motor, which can accelerate the cooling speed and solidification process of the casting. However, the heat dissipation effect of air cooling alone is not good. During the air cooling process, the thickness of the die casting is uneven, which can cause local overheating of the die casting under the influence of the air cooling device, affecting the quality of the die casting. Summary of the Invention

[0004] Therefore, the purpose of this utility model is to provide a heat dissipation device for radiator die castings to solve the technical problem of local overheating in single air-cooled radiator die castings.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a heat dissipation device for die-cast radiators, comprising a conveying assembly and a heat dissipation assembly; The conveying assembly includes multiple conveying shafts, a frame, and multiple motors. The conveying shafts are rotatably connected to the frame, and the motors control the rotation of the transmission shafts. The heat dissipation assembly includes a heat dissipation box, a water tank, a first water pump, a second water pump, heat dissipation plates, an outlet pipe, an inlet pipe, a connecting pipe, and multiple heat dissipation pipes. The water tank is fixedly connected to the bottom of the heat dissipation box. The first and second water pumps are both fixedly connected to the top of the water tank. The heat dissipation pipes are fixedly connected to the frame. The transmission shaft is sleeved on the heat dissipation pipes. The heat dissipation pipes are connected to each other through connecting pipes. The input end of the first water pump is located inside the water tank. The output end of the first water pump is connected to the input end of the heat dissipation pipe through the outlet pipe. The output end of the heat dissipation pipe is connected to the input end of the second water pump through the inlet pipe. The output end of the second water pump is located inside the water tank. Multiple heat dissipation plates are fixedly connected to the outer wall of the portion of the inlet pipe inside the heat dissipation box. Multiple heat exhaust fans are provided on the outer wall of the heat dissipation box.

[0006] By adopting the above technical solution, multiple conveyor shafts in the conveying assembly rotate on the frame, stably receiving and conveying die-cast parts. The motor precisely controls the rotation of the conveyor shafts, and the transmission speed can be flexibly adjusted according to the heat dissipation requirements of the die-cast parts. The water tank provides a stable coolant storage space for heat dissipation. The cooperation of the first and second water pumps can drive the coolant to circulate efficiently in the loop composed of the heat dissipation pipe, the outlet pipe, the inlet pipe, and the connecting pipe. When the coolant flows through the heat dissipation pipe connected to the conveyor shaft, it can quickly absorb the heat transferred by the die-cast parts on the conveyor shaft, achieving direct cooling of the die-cast parts. The inlet pipe is located on the outer wall of the inner part of the heat dissipation box, where multiple heat dissipation plates can quickly conduct the heat absorbed by the coolant to the air. Multiple exhaust fans on the outer wall of the heat dissipation box then promptly exhaust the hot air inside the heat dissipation box, further improving the cooling effect of the coolant and ensuring that the coolant maintains good heat dissipation capacity during circulation.

[0007] Furthermore, multiple cooling fans are fixedly connected to the top of the frame.

[0008] By adopting the above technical solution, multiple cooling fans are fixedly connected above the frame, which can actively cool the die-cast parts being transported on the conveying assembly. This complements the liquid cooling of the heat pipes in the heat dissipation assembly. The cooling fans are installed above the frame, and their airflow direction can accurately cover the die-cast parts transport area on the conveying assembly without interfering with the normal operation of the conveying assembly. Moreover, the setting of multiple cooling fans can achieve full coverage of the die-cast parts transport path, ensuring that each die-cast part can be evenly cooled during the transport process.

[0009] Furthermore, the central axes of the transmission shafts are all in the same plane, and the plane formed by the central axes of the transmission shafts is parallel to the horizontal plane.

[0010] By adopting the above technical solution, the central axis of the conveyor shaft is set in the same plane and the plane is parallel to the horizontal plane. This ensures that the top conveying surface of all conveyor shafts is kept at the same horizontal height. When the die-cast part is placed on the conveyor shaft for transmission, the bottom of the die-cast part can make uniform contact with multiple conveyor shafts, avoiding the die-cast part from tilting due to inconsistent height of the conveyor shafts.

[0011] Furthermore, gears are fixedly connected to the ends of the transmission shafts, and the transmission shafts are connected to each other by toothed belts.

[0012] By adopting the above technical solution, a gear is fixedly connected to the end of the transmission shaft, and each transmission shaft is connected by a toothed belt. This enables the synchronous rotation of multiple transmission shafts, avoids the speed difference that may occur when a single motor controls a single transmission shaft, and ensures that the die-cast parts always move smoothly during transmission.

[0013] Furthermore, the heat dissipation pipe and the connecting pipe are connected to form a continuous pipe.

[0014] By adopting the above technical solution, the heat dissipation pipe and the connecting pipe are connected to form a continuous pipe, which can ensure that the coolant forms a complete and continuous circulation path in the heat dissipation component, avoid the problem of coolant stagnation or leakage caused by poor connection between the heat dissipation pipe and the connecting pipe, ensure the stability and efficiency of coolant circulation, and improve heat dissipation efficiency.

[0015] Furthermore, the portion of the liquid inlet pipe located outside the heat sink is a plastic flexible tube, while the portion of the liquid inlet pipe located inside the heat sink is a metal tube.

[0016] By adopting the above technical solution, the part of the liquid inlet pipe located outside the heat sink is made into a plastic hose, which takes advantage of the soft and flexible nature of the plastic hose to facilitate the connection between the heat sink and external components.

[0017] Furthermore, the exhaust fan's air outlet is aligned with the heat sink plate.

[0018] By adopting the above technical solution, the air outlet of the heat dissipation fan is directed at the heat sink, allowing the airflow generated by the heat dissipation fan to act directly on the surface of the heat sink, quickly removing the heat conducted on the heat sink, avoiding heat accumulation on the surface of the heat sink that would lead to a decrease in heat dissipation efficiency, and ensuring that the heat sink can continuously and efficiently conduct the heat of the coolant in the inlet pipe to the air, thereby ensuring the cooling effect of the coolant.

[0019] In summary, the present invention has the following main advantages: This utility model utilizes a conveyor shaft that rotates on a frame to stably transport die-cast parts, a water tank that stores coolant, and a first and second water pump that drives the coolant to circulate in a loop consisting of a heat dissipation pipe, an outlet pipe, an inlet pipe, and a connecting pipe. The combination of the conveyor shaft and the heat dissipation pipe effectively absorbs the heat from the die-cast parts, and the combination of multiple heat dissipation pipes and a cooling fan prevents localized overheating of the die-cast parts. This invention achieves synchronous rotation by connecting the gear at the end of the transmission shaft to the toothed belt, avoiding the offset and jamming of the die-casting part caused by the difference in rotation speed, ensuring that the air blown by the cooling fan and the heat dissipation pipe are in uniform contact with the die-casting part, and further preventing local overheating.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0023] In this example: a heat dissipation device for a die-cast radiator, such as... Figure 1-5 As shown, it includes a transmission component and a heat dissipation component; The conveying assembly includes multiple conveying shafts 11, a frame 12, and multiple motors 13. The conveying shafts 11 are rotatably connected to the frame 12. The multiple conveying shafts 11 in the conveying assembly rotate on the frame 12, which can stably receive and transport the die-cast parts. The motors 13 control the rotation of the transmission shafts. The motors 13 can precisely control the rotation of the conveying shafts 11 and can flexibly adjust the transmission speed according to the heat dissipation requirements of the die-cast parts. The heat dissipation assembly includes a heat dissipation box 21, a water tank 22, a first water pump 23, a second water pump 24, a heat dissipation plate 25, an outlet pipe 26, an inlet pipe 27, a connecting pipe 28, and multiple heat dissipation pipes 29. The water tank 22 is fixedly connected to the bottom of the heat dissipation box 21, providing a stable coolant storage space and an installation platform for other structures. The first water pump 23 and the second water pump 24 are both fixedly connected to the top of the water tank 22. The cooperation of the first water pump 23 and the second water pump 24 drives the coolant. The heat dissipation pipes 29 are fixedly connected to the frame 12, and the transmission shaft 11 is sleeved on the heat dissipation pipes 29. The central axes of the heat dissipation pipes 29 are all in the same plane and parallel to the horizontal plane. The heat dissipation pipes 29 are connected to each other through the connecting pipes 28, forming a circulation loop. The input end of the first water pump 23 is located at... Inside the water tank 22, the output end of the first water pump 23 is connected to the input end of the heat dissipation pipe 29 through the liquid outlet pipe 26. The output end of the heat dissipation pipe 29 is connected to the input end of the second water pump 24 through the liquid inlet pipe 27. The output end of the second water pump 24 is located inside the water tank 22. The cooperation of the first water pump 23 and the second water pump 24 can drive the coolant to circulate efficiently in the loop composed of the heat dissipation pipe 29, the liquid outlet pipe 26, the liquid inlet pipe 27 and the connecting pipe 28. Multiple heat dissipation plates 25 are fixedly connected to the outer wall of the part of the liquid inlet pipe 27 inside the heat dissipation box 21, which can quickly conduct the heat absorbed by the coolant to the air, forming efficient heat dissipation for the coolant. Multiple heat exhaust fans 210 are provided on the outer wall of the heat dissipation box 21, which then exhaust the hot air inside the heat dissipation box 21 in a timely manner, further improving the cooling effect of the coolant.

[0024] See Figure 1 , Figure 2 Multiple cooling fans 211 are fixedly connected to the top of the frame 12. The cooling fans 211 are installed on the top of the frame 12, and their air blowing direction can accurately cover the die-casting part transmission area on the transmission component, without interfering with the normal operation of the transmission component. Moreover, the setting of multiple cooling fans 211 can achieve full coverage of the die-casting part transmission path.

[0025] See Figure 1 , Figure 3 The central axes of the conveying shafts 11 are all in the same plane, and the plane formed by the central axes of the conveying shafts 11 is parallel to the horizontal plane, ensuring that the top conveying surfaces of all conveying shafts 11 are kept at the same horizontal height. When the die-cast part is placed on the conveying shaft 11 for transmission, the bottom of the die-cast part can make uniform contact with multiple conveying shafts 11. See Figure 3 Each end of the transmission shaft 11 is fixedly connected to a gear 14, and the transmission shafts 11 are connected to each other by a toothed belt 15 to achieve synchronous rotation of multiple transmission shafts 11 and avoid the speed difference that may occur when a single motor 13 controls a single transmission shaft 11. See Figure 2 The heat dissipation pipe 29 and the connecting pipe 28 are connected to form a continuous pipe, ensuring that the coolant forms a complete and continuous circulation path in the heat dissipation assembly, so that the coolant can flow evenly through each section of the heat dissipation pipe 29 and fully absorb the heat of the die-cast parts on each transmission shaft 11. See Figure 1 The portion of the inlet pipe 27 located outside the heat sink 21 is a plastic hose. The plastic hose is soft and flexible, making it easy for workers to install and move. The portion of the inlet pipe 27 located inside the heat sink 21 is a metal pipe. Taking advantage of the good thermal conductivity of metal, the heat absorbed by the coolant in the inlet pipe 27 can be quickly conducted to the outer wall of the metal pipe, and then dissipated through the heat dissipation plate 25 on the outer wall of the metal pipe, thereby improving the cooling efficiency of the coolant in the heat sink 21. See Figure 5 The exhaust fan 210 operates with its air outlet aligned with the heat sink 25. This allows the airflow generated by the exhaust fan 210 to directly act on the surface of the heat sink 25, quickly removing the heat conducted on the heat sink 25.

[0026] The implementation principle of this embodiment is as follows: First, the die-cast radiator to be cooled is placed on the conveyor shaft 11 of the conveyor assembly. After the motor 13 starts, it drives all the conveyor shafts 11 to rotate synchronously on the frame 12 through the transmission action of the end gear 14 and the toothed belt 15. Since the central axis of the conveyor shaft 11 is coplanar and parallel to the horizontal plane, the die-cast part can be conveyed at a uniform speed on the horizontal and stable conveyor surface. The cooling fan 211 above the frame 12 starts to cool the surface of the die-cast part. The first water pump 23 draws out the coolant in the water tank 22 and discharges it through the outlet pipe. 26 is delivered to the heat dissipation pipe 29 connected to the transmission shaft 11. When the coolant flows in the heat dissipation pipe 29, it absorbs the heat transferred to the transmission shaft 11 by the die-casting. Then, the coolant carrying heat is collected through the connecting pipe 28 and passes through the inlet pipe 27. The heat dissipation plate 25 on the outer wall of the metal pipe section of the inlet pipe 27 conducts the heat of the coolant into the air. The heat dissipation fan 210 on the outer wall of the heat dissipation box 21 blows air towards the heat dissipation plate 25 to quickly exhaust the hot air to cool the coolant. Finally, the cooled coolant is pumped back to the water tank 22 by the second water pump 24 to complete the coolant circulation.
