Description

Technical Field

[0001] This application relates to the field of heat dissipation technology, and in particular to a heat dissipation component and electrical device. Background Technology

[0002] As the power of electrical equipment continues to increase, the heat generated also gradually increases, and fans are usually installed in the equipment for heat dissipation. Due to limitations such as installation environment, the air outlets of such equipment often face walls or other cabinets, and in order to make full use of space, the equipment is installed in relatively close proximity. Direct air ducts or downward-facing air outlets are commonly used; however, this can easily cause some hot air to flow back to the air inlet of the unit or other equipment, resulting in the actual air inlet temperature of the equipment in the entire site being 5 to 10°C higher than the ambient temperature, creating a heat island effect. Utility Model Content

[0003] Therefore, it is necessary to provide a heat dissipation component and device to reduce the heat island effect.

[0005] Understandably, airflow converges within the heat sink casing, carrying away heat and achieving heat exchange. The airflow guide structure directs the heat-exchanged airflow outwards. Specifically, the first air guide plate directs the airflow to the second air guide plate, which then guides the airflow upwards at an angle out of the heat sink. The hot air naturally rises into the environment, preventing it from quickly flowing back to the heat sink's inlet, thus minimizing the increase in inlet air temperature and reducing the heat island effect.

[0010] In one embodiment, the air guiding structure further includes a connecting plate. Along the second direction, the connecting plate is provided on both sides of the first air guiding plate and the second air guiding plate. The first air guiding plate is connected to the second air guiding plate through the connecting plate, and the air guiding structure is installed on the heat dissipation housing through the connecting plate. The first air guide plate and the second air guide plate are spaced apart and together with the connecting plate form a drain outlet; The first direction, the second direction, and the height direction are set at angles to each other.

[0011] In one embodiment, the first air guide plate and the second air guide plate are integrally formed, and the air guide structure is processed by bending process to form the first air guide plate and the second air guide plate; The air guide structure is manufactured using a stamping process to create the drainage outlet.

[0012] In one embodiment, the air guiding structure is provided with a guide plate, which is located below the drain outlet; The air guide plate is disposed at one end of the first air guide plate, and the air guide plate is inclined toward the outside of the heat dissipation housing; or, the air guide plate is disposed at one end of the second air guide plate, and the air guide plate is inclined toward the air outlet and there is a gap between the air outlet and the air outlet.

[0013] In one embodiment, along the second direction, the heat dissipation component includes at least two of the air guide structures, with adjacent air guide structures interconnected; and / or, along the height direction, the heat dissipation component includes a plurality of the air guide structures, with the plurality of air guide structures spaced apart. The first direction, the second direction, and the height direction are set at angles to each other.

The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0023] Please see Figures 1 to 5 This application provides a heat dissipation component 100, which includes a heat dissipation housing 10 and an air guide structure 20. The heat dissipation housing 10 has an air inlet 101 on one side along a first direction and an air outlet 102 on the other side. Airflow flows into the heat dissipation housing 10 from the air inlet 101, exchanges heat with the energy-consuming component 200, and then flows out from the air outlet 102. The air guide structure 20 is installed at the air outlet 102 to guide the airflow at the air outlet 102 for output.

[0024] like Figure 1 As shown, this application also provides an electrical device 1000, including an energy-consuming component 200 and the aforementioned heat dissipation component 100. The heat dissipation component 100 is disposed at the top of the energy-consuming component 200 and is used to dissipate heat from the energy-consuming component 200, maintain the normal operation of the energy-consuming component 200, and extend the service life of the energy-consuming component 200.

[0025] like Figures 3 to 5As shown, in an optional embodiment, the air guiding structure 20 includes a first air guiding plate 21 and a second air guiding plate 22, which are connected and angled together. Along a first direction, the first air guiding plate 21 is positioned closer to the air inlet 101 than the second air guiding plate 22, guiding airflow towards the first air guiding plate 21. The second air guiding plate 22 is inclined upwards along the height direction from its end closest to the first air guiding plate 21, with at least a portion of its structure located outside the air outlet 102 to guide the airflow from the air outlet 102 upwards. Because the airflow has a higher temperature and lower density after heat exchange, it can naturally and continuously rise into the environment, and is less likely to directly flow back to the air inlet 101 of the heat dissipation housing 10 upon encountering obstacles such as walls, thus minimizing the temperature rise of the air inlet 101 and ensuring the heat dissipation effect of the heat dissipation component 100. Especially when the energy-consuming component 200 and the heat dissipation component 100 are densely assembled, this arrangement can significantly reduce hot air recirculation, alleviate the heat island effect, and improve the overall system energy efficiency.

[0026] The first direction and the height direction are set at an angle. For ease of explanation, this application also provides a second direction, which limits the first direction, the second direction, and the height direction to be set perpendicular to each other, and is described with the first direction as the x-axis, the second direction as the y-axis, and the height direction as the z-axis.

[0027] In a specific embodiment, the heat dissipation component 100 includes a fan, which is disposed inside the heat dissipation housing 10 to draw in airflow and accelerate the airflow heat exchange rate.

[0028] like Figure 2 and Figure 3 As shown, in an optional embodiment, the first air guide plate 21 is inclined downwards along the height direction from the end near the air outlet 102 in the first direction. This guides the airflow from the air outlet 102 to the second air guide plate 22 while simultaneously preventing rain, snow, and foreign objects from entering the heat dissipation housing 10, ensuring the reliability of the heat dissipation component 100. Especially in extreme weather conditions, the effective blocking of rain, snow, and foreign objects by the first air guide plate 21 allows the heat dissipation component 100 to be used in extreme weather situations, broadening its application scenarios.

[0029] like Figure 3 As shown, in an optional embodiment, the angle between the tilt direction of the first air guide plate 21 and the first direction is α, and the angle between the tilt direction of the second air guide plate 22 and the first direction is β, where α < β. That is, the tilt angle of the second air guide plate 22 is greater than that of the first air guide plate 21. This arrangement ensures that the first air guide plate 21 effectively guides the airflow upwards. At the same time, the tilt angle of the first air guide plate 21 is small, which can reduce the obstruction of airflow while blocking rain, snow, and foreign objects, ensuring smooth airflow and avoiding excessive energy consumption of the fan, thus avoiding additional burden.

[0030] like Figure 3 As shown, in a specific embodiment, the angle α between the tilt direction of the first air guide plate 21 and the first direction satisfies: 3°≤α≤30°. By limiting the tilt angle of the first air guide plate 21, the airflow guiding effect of the first air guide plate 21 is ensured, and the first air guide plate 21 is prevented from obstructing the flow of hot air. At the same time, it can also obstruct rain, snow, and foreign objects. For example, α=3°, 15°, or 30°.

[0031] like Figure 3 As shown, in a specific embodiment, the angle β between the tilt direction of the second air guide plate 22 and the first direction satisfies: 30°≤β≤60°. By limiting the tilt angle range of the second air guide plate 22, sufficient air guiding effect is ensured, avoiding insufficient tilt angle that fails to effectively guide the hot airflow upward, and also avoiding excessive tilt angle that hinders the smooth flow of hot air. For example, β = 30°, 45°, or 60°.

[0032] like Figure 4 and Figure 5 As shown, in a specific embodiment, the air guide structure 20 further includes a connecting plate 23. Along the second direction, the first air guide plate 21 and the second air guide plate 22 are respectively provided with connecting plates 23 on both sides. The first air guide plate 21 is connected to the second air guide plate 22 through the connecting plate 23. The air guide structure 20 is installed on the heat dissipation shell 10 through the connecting plate 23, which facilitates the assembly and fixation of the air guide structure 20.

[0033] like Figures 3 to 5 As shown, in an optional embodiment, the air guide structure 20 is provided with a drain outlet 201 for discharging rain and snow that are blocked by the first air guide plate 21.

[0034] like Figures 3 to 5 As shown, in a specific embodiment, the drain outlet 201 is located between the first air guide plate 21 and the second air guide plate 22. Since the first air guide plate 21 is inclined downward and the second air guide plate 22 is inclined upward, that is, a drain outlet 201 is provided at the bottom of the air guide structure 20 so that when rain and snow enter the air guide structure 20, they can be discharged through the drain outlet 201 at the bottom of the air guide structure 20, thereby avoiding the accumulation of rain and snow.

[0035] like Figure 4 and Figure 5 As shown, in a specific embodiment, the first air guide plate 21 and the second air guide plate 22 are spaced apart and surround the connecting plate 23 to form a drain outlet 201, so as to ensure that the drain outlet 201 is located at the bottom of the air guide structure 20. This arrangement helps to reduce the impact on the air guide, and the airflow at the bottom can also promote drainage.

[0036] In other embodiments, the first air guide plate 21 and the second air guide plate 22 are connected, and the drain outlet 201 can also be located at the end of the first air guide plate 21 near the second air guide plate 22. Alternatively, the first air guide plate 21 and the second air guide plate 22 are connected, and the drain outlet 201 is located at the end of the second air guide plate 22 near the first air guide plate 21. No specific limitation is made here; it is sufficient that rain, snow, etc., are discharged from the drain outlet 201.

[0037] like Figure 3 As shown, in a specific embodiment, the air guide structure 20 is provided with a guide plate 24, which is located below the drain outlet 201 to receive water and foreign objects discharged from the drain outlet 201 and guide the water and foreign objects discharged from the drain outlet 201 to flow out towards the outside of the heat dissipation component 100.

[0038] In a specific embodiment, the guide plate 24 is disposed at one end of the first air guide plate 21. The guide plate 24 is inclined toward the outside of the heat dissipation housing 10 to form an inclined guide surface, which effectively guides the water and foreign objects at the drain outlet 201 to be discharged toward the outside of the heat dissipation housing 10, thereby accelerating the discharge speed of water and foreign objects.

[0039] like Figure 2 and Figure 3 As shown, in another specific embodiment, the guide plate 24 is disposed at one end of the second guide plate 22. The guide plate 24 is inclined toward the air outlet 102 and there is a gap between it and the air outlet 102 to form an inclined guide surface, and effectively guides the water and foreign objects at the drain outlet 201 to be discharged on the outside of the heat dissipation housing 10, so as to prevent water and foreign objects from entering the heat dissipation housing 10.

[0040] In a specific embodiment, the first air guide plate 21 and the second air guide plate 22 are integrally formed, which helps to ensure structural strength. The air guide structure 20 is processed by bending to form the first air guide plate 21 and the second air guide plate 22, and the air guide structure 20 is processed by stamping to form the drain outlet 201, which is simple to operate and has high processing efficiency. When the first air guide plate 21 and the second air guide plate 22 are respectively connected to the connecting plate 23, the first air guide plate 21, the second air guide plate 22 and the connecting plate 23 are integrally formed.

[0041] In other embodiments, the first air guide plate 21 and the second air guide plate 22 can also be set separately and connected and fixed by welding, riveting or other means with the connecting plate 23.

[0042] like Figure 4 and Figure 5As shown, in a specific embodiment, along the second direction, the heat dissipation component 100 includes at least two air guide structures 20, and two adjacent air guide structures 20 are connected to each other. This arrangement allows for flexible adjustment of the number of air guide structures 20 according to the area of ​​the air outlet 102, making the assembly of the air guide structures 20 more convenient, and helping to maintain structural strength, avoiding the air guide structures 20 from being too large and easily damaged.

[0043] like Figure 2 As shown, in a specific embodiment, along the height direction, the heat dissipation component 100 includes a plurality of air guiding structures 20, which are arranged at intervals to guide the airflow at various positions in the height direction, thereby forming a larger airflow area and promoting the airflow effect.

[0044] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0045] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
