Description

Technical Field

[0001] This utility model relates to the field of air-cooled radiator technology, and in particular to a cast radiator. Background Technology

[0002] Air-cooled radiators are devices that dissipate heat through air convection and metal conduction. They are widely used in electronic equipment, power electronics, industrial machinery and other fields. Their core principle is to increase the heat dissipation area by using heat sink fins and accelerate heat dissipation by using a fan to force convection.

[0003] During operation, air-cooled radiators direct the airflow generated by the fan to the heatsink fins for heat dissipation. However, as the airflow is directed to the heatsink fins, it disperses, resulting in a slower airflow speed in contact with the heatsink fins. This obstructs the airflow over the surface of the heatsink fins, leading to insufficient heat dissipation efficiency and reduced cooling effect. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where gas scatters during the process of guiding airflow to the heat sink fins, resulting in slow airflow velocity in contact with the heat sink fins and poor airflow on the surface of the heat sink fins, thus leading to insufficient heat dissipation efficiency and reduced heat dissipation effect. Therefore, this invention proposes a cast radiator.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] Design a castable heat sink, including a base plate, on which a plurality of heat dissipation fins are welded at equal intervals along the length direction. Each heat dissipation fin has a through hole, and a pipe is inserted into the through hole. A plurality of connecting rods are fixedly connected to the base plate. The connecting rods are located on the same side as the heat dissipation fins. One end of each connecting rod is fixedly connected to the same air guide shroud. The air guide shroud is in contact with the heat dissipation fins and has an air outlet that faces the heat dissipation fins.

[0007] Preferably, each of the through holes is connected to a graphene gasket, and the graphene gasket is in contact with the pipe.

[0008] Preferably, each of the heat dissipation fins is provided with a nickel plating layer.

[0009] Preferably, each of the heat dissipation fins has a plurality of grooves evenly spaced along its length.

[0010] Preferably, a noise reduction mechanism is connected inside the air guide shroud. The noise reduction mechanism includes several mounting slots, which are opened onto the inner wall of the air guide shroud. Each mounting slot is connected to a sound-absorbing filler layer. Several wind-damping components are fixedly connected to the air outlet along its length.

[0011] Preferably, the sound-absorbing filler layer is a polyurethane foam layer.

[0012] Preferably, the wind-damaging component includes a fixing plate, which is fixedly connected to the air outlet, and the fixing plate has a plurality of dispersed teeth evenly spaced along its length.

[0013] Preferably, the fixing plate and the plurality of dispersing teeth are an integral structure.

[0014] The advantages of the cast radiator proposed in this utility model are as follows:

[0015] Cooling gas generated by the fan is guided into the air guide shroud, which directs the air-cooled gas. The air-cooled gas inside the air guide shroud passes through the air outlet and comes into contact with the heat dissipation fins, thus cooling the heat dissipation fins. The air guide shroud also directs the gas released by the fan, concentrating the airflow through the heat dissipation fin area, making the airflow on the surface of the heat dissipation fins smooth and improving the heat dissipation efficiency.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1: Refer to Figure 1-3A castable heat sink includes a base plate 1, which is an AL1100 aluminum alloy base plate. The base plate 1 is manufactured by casting high thermal conductivity aluminum ingots into molten aluminum using a casting process, resulting in a complex shape with good integrity and heat dissipation performance. A plurality of heat dissipation fins 2 are welded at equal intervals along the length of the base plate 1. The heat dissipation fins 2 are AL1100 aluminum alloy toothed plates, giving them good corrosion resistance, machinability, and thermal conductivity. Both the base plate 1 and the heat dissipation fins 2 are made of AL1100 aluminum alloy to ensure compatibility and overall heat dissipation performance. Each heat dissipation fin 2 is coated with a nickel plating layer, which improves the thermal conductivity of the surface of the heat dissipation fin 2. Each heat sink fin 2 has through holes 3, through which pipes 4 are inserted. Each through hole 3 contains a graphene pad. The graphene pad has high thermal conductivity, which facilitates the transfer of heat from the pipes 4 to the heat sink fins 2. The graphene pad is in contact with the pipes 4. Each heat sink fin 2 has several grooves 5 evenly spaced along its length. The grooves 5 increase the heat dissipation area of ​​the heat sink fin 2 and improve the heat dissipation effect. Several connecting rods 6 are fixedly connected to the base plate 1. The connecting rods 6 are located on the same side as the heat sink fins 2. One end of each connecting rod 6 is fixedly connected to the same air guide shroud 7. The air guide shroud 7 is in contact with the heat sink fins 2. An air outlet 8 is opened on the air guide shroud 7 and faces the heat sink fins 2.

[0023] Work process:

[0024] The air guide shroud 7 is connected to an external fan, and several connecting rods 6 fix the air guide shroud 7. The cooling gas generated by the fan is introduced into the air guide shroud 7, and the air guide shroud 7 guides the air-cooled gas. The air-cooled gas inside the air guide shroud 7 passes through the air outlet 8 and contacts the heat dissipation fins 2, thus cooling the heat dissipation fins 2. The air guide shroud 7 guides the gas released by the fan, and concentrates the airflow through the area of ​​the heat dissipation fins 2, so that the airflow on the surface of the heat dissipation fins 2 is smooth and the heat dissipation efficiency is improved.

[0025] Example 2: The air released by the fan is guided by the air guide shroud 7, concentrating the airflow through the area of ​​the heat dissipation fins 2, making the airflow on the surface of the heat dissipation fins 2 smooth and improving the heat dissipation efficiency. However, high-speed airflow passing through the air guide shroud 7 is prone to generating turbulence noise, which is relatively loud. (Refer to...) Figure 2-4 As another preferred embodiment of this utility model, the difference from embodiment 1 is that a noise reduction mechanism 9 is connected inside the air guide shroud 7. The noise reduction mechanism 9 includes several mounting slots 91, which are opened to the inner wall of the air guide shroud 7. Each mounting slot 91 is connected to a sound-absorbing filler layer 92, which is a polyurethane foam layer. Several wind-damping components are fixedly connected to the air outlet 8 along the length direction.

[0026] The wind-powered destructive component includes a fixed plate 93, which is fixedly connected to the air outlet 8. The fixed plate 93 is connected with a number of dispersing teeth 94 at equal intervals along its length. The fixed plate 93 and the number of dispersing teeth 94 are an integral structure.

[0027] The sound-absorbing filler layer 92 is placed in the mounting groove 91 to reduce the noise generated by the gas during the flow of the air guide 7. At the same time, when the gas is released from the air outlet 8, it comes into contact with several dispersive teeth 94 to disrupt the eddy current and reduce the howling, thereby reducing the noise level.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
