Description

Technical Field

[0001] This utility model relates to the field of heat sinks, and in particular to a heat sink with a flow guiding structure and its heat dissipation module. Background Technology

[0002] In fields such as electronic equipment, automotive electronics, and industrial control, as the power density of equipment continues to increase, the amount of heat generated increases dramatically. If the heat cannot be dissipated in time, it will lead to excessively high equipment temperatures, which in turn will affect the performance, stability, and lifespan of the equipment.

[0003] Heat sinks, as a commonly used passive heat dissipation component, are widely used in various heat dissipation scenarios due to their simple structure, low cost, and high reliability. Most existing heat sinks consist of a substrate and fins. Heat is transferred to the fins through the substrate, and then dissipated through heat exchange between the fins and the air.

[0004] However, in actual use, this traditional heat sink structure has obvious problems with uneven airflow distribution. When the airflow flows through the gaps between the fins, it is easy to form eddies or airflow stagnation areas at the root of the fins and the corners, resulting in poor airflow in these areas, heat accumulation, and a significant reduction in heat dissipation efficiency. The lack of airflow guidance design not only makes it easy for airflow to leak, but also further aggravates the problem of insufficient heat dissipation efficiency due to airflow turbulence.

[0005] Therefore, it is necessary to provide a heat sink with a flow guiding structure and its heat dissipation module to solve the above-mentioned technical problems. Utility Model Content

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] First Embodiment

[0027] Please refer to the following: Figure 1 , Figure 2 and Figure 3 ,in, Figure 1 A schematic diagram of a heat sink with a flow guiding structure provided by this utility model; Figure 2 for Figure 1 The diagram shows a rear view of the flow guide tube. Figure 3 for Figure 1 The diagram shows a cross-sectional view of the guide tube.

[0028] A heat sink with a flow guiding structure includes: a flow guiding cylinder 1;

[0029] A slot 2 is formed in the middle of the front of the guide tube 1. A plurality of heat dissipation devices 3 are provided on one side inside the slot 2. The heat dissipation device 3 includes heat dissipation fins 31 and connecting grooves 32. The plurality of heat dissipation fins 31 are equidistantly mounted around the surface of the inner wall of the slot 2, and the plurality of connecting grooves 32 are equidistantly formed on the surface of the heat dissipation fins 31.

[0030] A guide device 6, a plurality of guide devices 6 are equidistantly mounted around the other side of the opening slot 2. The guide device 6 includes a first guide block 61, a second guide block 62, a guide groove 63 and a blocking protrusion 64. The first guide block 61 and the second guide block 62 are respectively mounted on both sides of the opening slot 2. The guide groove 63 is opened on one side of the surface of the first guide block 61 and the second guide block 62. A plurality of blocking protrusions 64 are mounted on the surface of the guide groove 63.

[0031] A heat-conducting plate 4 is fixedly installed on the rear side of the outer surface of the guide tube 1, and a ventilation groove 5 is formed on the surface of the heat-conducting plate 4.

[0032] A support base 7 is fixedly installed on the bottom of the outer surface of the guide tube 1. The support base 7 has a mounting groove 8 on both sides of the top, and a bolt hole 9 is provided in the middle of the bottom of the mounting groove 8.

[0033] The guide groove 63 between the first guide block 61 and the second guide block 62 is V-shaped.

[0034] The guide groove 63 between the first guide block 61 and the second guide block 62 is V-shaped, with a large opening on the side closer to the heat conduction plate 4 and a small opening on the side closer to the heat dissipation device 3, which reduces the airflow velocity. Multiple blocking protrusions 64 increase the blocking effect on the airflow, making the airflow towards the guide device 6 and the heat dissipation device 3 slow down, thereby increasing the heat dissipation effect on the airflow.

[0035] The heat-conducting plate 4, the flow guide tube 1, and the heat dissipation fins 31 are all made of aluminum heat dissipation material.

[0036] The working principle of the heat sink with a flow guiding structure provided by this utility model is as follows:

[0037] During operation, the support base 7 is first installed by bolts to limit its position, so that the heat-conducting plate 4 is attached to the surface of the electronic component.

[0038] The ventilation groove 5 facilitates airflow on the surface of the heat-conducting plate 4, carrying away more heat. Heat enters the interior of the guide tube 1 through the heat-conducting plate 4 and the ventilation groove 5, and passes through the guide groove 63 between the first guide block 61 and the second guide block 62. The "V"-shaped guide groove 63 guides the heat to the heat dissipation fins 31. As the opening of the guide groove 63 narrows, the airflow speed is reduced, allowing the airflow to exchange heat more fully with the heat dissipation fins 31. The block 64 further disperses and guides the airflow, and the airflow flows evenly through each heat dissipation fin 31, improving heat dissipation efficiency. The connecting groove 32 on the heat dissipation fins 31 increases the airflow channel and enhances the contact area between the air and the heat dissipation fins 31.

[0039] Compared with related technologies, the heat sink with a flow guiding structure provided by this utility model has the following beneficial effects:

[0040] This utility model provides a heat sink with a flow guiding structure. A flow guiding cylinder 1 and a heat-conducting plate 4 are mounted and attached to the surface of the electronic component requiring heat dissipation via a support base 7. A "V"-shaped guide groove 63, formed by a first guide block 61 and a second guide block 62, guides heat towards the heat dissipation fins 31. The first and second guide blocks 61 and 62 slow down the airflow, reducing its speed and allowing for more thorough heat exchange with the heat dissipation fins 31. Simultaneously, blocking protrusions 64 further disperse and guide the airflow, preventing eddies or stagnation in localized areas and ensuring uniform airflow across all heat dissipation fins 31, thus improving heat dissipation efficiency. The connecting grooves 32 on the heat dissipation fins 31 are increased... The airflow channel is improved, enhancing the contact area between the air and the heat dissipation fins 31 and further improving the heat exchange effect. The heat-conducting plate 4 quickly conducts the heat generated by the electronic components to the airflow guide tube 1, and then through the airflow guide tube 1 to the heat dissipation device 3 for heat dissipation. The venting groove 5 helps the air to flow on the surface of the heat-conducting plate 4, carrying away more heat. This effectively solves the problems of uneven airflow distribution and low heat dissipation efficiency of traditional heat sinks. The heat sink with the airflow guide structure achieves airflow guidance and efficient heat conduction through the unique airflow guide structure design, which can significantly reduce the operating temperature of electronic components, improve the stability and service life of the equipment, and significantly improve its heat dissipation efficiency compared with traditional heat sinks.

[0041] Second Embodiment

[0042] Please refer to the following: Figure 4 and Figure 5 Based on the heat dissipation module with a heat sink having a flow guiding structure provided in the first embodiment of this application, the second embodiment of this application proposes another heat dissipation module with a heat sink having a flow guiding structure. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0043] Specifically, the difference in the heat dissipation module with a heat sink with a flow guiding structure provided in the second embodiment of this application is that the heat dissipation module with a heat sink with a flow guiding structure includes: a first air-gathering shroud 10;

[0044] The second gas-gathering hood 12 is disposed on one side of the first gas-gathering hood 10. An exhaust pipe 14 is fixedly installed in the middle of one side of the second gas-gathering hood 12. An installation plate 15 is fixedly installed on one side of the exhaust pipe 14. An exhaust groove 16 is opened on the surface of the installation plate 15. A fan 17 is disposed in the middle of the surface of the installation plate 15.

[0045] A first connecting flange 11 is fixedly installed on the outer surface of the first gas-gathering hood 10.

[0046] A second connecting flange 13 is fixedly installed on the outer surface of the second gas-gathering hood 12.

[0047] The fan 17 includes a servo motor, a rotating shaft, and a fan, which is existing technology.

[0048] The first connecting flange 11 and the second connecting flange 13 are assembled by bolts.

[0049] The working principle of the heat dissipation module with a heat sink and a flow guiding structure provided by this utility model is as follows:

[0050] During operation, the first gas-gathering hood 10 and the second gas-gathering hood 12 are first connected and installed through the first connecting flange 11 and the second connecting flange 13, so that the exhaust pipe 14 and the fan 17 are installed on the air outlet side of the guide pipe 1, and the heat dissipation fins 31 are placed in the relatively enclosed space formed by the first gas-gathering hood 10 and the second gas-gathering hood 12.

[0051] When the fan 17 is started, the fan 17 generates suction, which causes the heat from the electronic components and the air to pass through the guide device 6 and the heat dissipation device 3 inside the guide tube 1, carrying away the heat from the heat sink.

[0052] The air is then discharged through the exhaust pipe 14 on the second air-gathering hood 12. The exhaust groove 16 on the mounting plate 15 on one side of the exhaust pipe 14 helps the air to be discharged smoothly and avoids airflow obstruction. In this way, the combination of the air-gathering hood and the fan forms an effective air circulation system, which accelerates the flow of hot air and further improves the heat dissipation efficiency.

[0053] Compared with related technologies, the heat dissipation module with a heat sink and a flow guiding structure provided by this utility model has the following advantages:

[0054] This utility model provides a heat dissipation module with a heat sink with a flow guiding structure. The combination design of the first air-gathering cover 10 and the second air-gathering cover 12 facilitates the connection and fixation of the heat dissipation module with other devices, and can more effectively collect and guide the airflow around the heat sink. The exhaust pipe 14 and the exhaust groove 16 on the mounting plate 15 cooperate with each other to allow the airflow to be discharged smoothly. The fan 17 provides the power for active ventilation and accelerates the dissipation of heat. Combined with the flow guiding structure, a complete heat dissipation module is formed from heat conduction to airflow guidance to active ventilation. The comprehensive heat dissipation method greatly improves the heat dissipation efficiency, improves the uniformity of airflow and contact with the heat sink fins 31, can effectively reduce the operating temperature of the equipment, improve the stability and service life of the equipment, solve the problems of uneven airflow distribution and low heat dissipation efficiency of traditional heat sinks, and further improves the heat dissipation effect through the active ventilation design. It provides an efficient and stable heat dissipation solution for electronic equipment, automotive electronics, industrial control and other fields.
