Description

Technical Field

[0001] This utility model relates to the field of electrical equipment, and in particular to a heat dissipation component and electrical equipment. Background Technology

[0002] With the rapid development of electronic technology, the performance of electrical equipment is constantly improving, which in turn leads to a continuous increase in the heat generated by the internal components of electrical equipment. In order to ensure the normal operation of electrical equipment and extend its service life, heat dissipation has become an important aspect of electrical equipment design.

[0003] In related technologies, heat dissipation components for electrical equipment typically include structures such as cooling fans, which use the rotation of the fan to expel heat from inside the electrical equipment. Furthermore, for safety reasons and to prevent dust and impurities from entering the electrical equipment, a protective mesh cover is usually installed at the location of the fan. However, the presence of the protective mesh cover can obstruct some airflow through the fan, thereby reducing the heat dissipation effect and efficiency of the heat dissipation component. Utility Model Content

[0004] This utility model provides a heat dissipation component and an electrical device to solve at least one of the aforementioned technical problems.

[0005] The heat dissipation assembly of this utility model includes a main body and a protective mesh cover. The main body has a first through hole; the protective mesh cover is installed at the first through hole and protrudes from one side of the main body. A first flow channel is formed at the edge of the protective mesh cover and the first through hole, and the orientation of the first flow channel intersects with the orientation of the first through hole. The protective mesh cover has a second flow channel, and the orientation of the second flow channel is the same as the orientation of the first through hole.

[0006] In the heat dissipation assembly of this invention, since the protective mesh cover protrudes from one side of the main body and forms a first flow channel with the edge of the first through hole, airflow can flow from the first through hole to the first flow channel. This reduces the obstruction of airflow by the protective mesh cover, allowing airflow to pass through the protective mesh cover more smoothly, thereby improving the heat dissipation effect and efficiency.

[0007] Meanwhile, the first and second airflow channels of the protective mesh cover are oriented differently, allowing the protective mesh cover to guide airflow from different directions simultaneously. This enables the airflow to flow not only from the first through-hole to the first airflow channel, but also from the first through-hole to the second airflow channel. This increases the airflow path, helps to more effectively disperse and dissipate heat, and further improves the heat dissipation effect and efficiency.

[0008] In some embodiments, the protective mesh includes a protective section and a reinforcing section.

The first connecting rib is in the shape of a ring, and there are multiple first connecting ribs. The multiple first connecting ribs are arranged at intervals with the same center. The second connecting rib connects the multiple first connecting ribs.

[0011] In some embodiments, there are multiple reinforcing segments, which are spaced apart circumferentially along the protective segment; the first connecting rib includes an outer connecting rib, which is disposed on the outermost periphery of the multiple first connecting ribs, and the outer connecting rib includes a first connecting segment and a second connecting segment connected to the first connecting segment, the first connecting segment connecting the first ends of two adjacent reinforcing segments, and the width of the first connecting segment being greater than the width of the second connecting segment.

[0013] In some embodiments, there are multiple second connecting ribs, which intersect at the center of the first connecting rib, and the second connecting ribs and the first connecting rib form the second flow channel.

[0014] In some embodiments, the second flow channel includes a first flow sub-channel and a second flow sub-channel, with two adjacent second connecting ribs and the innermost first connecting rib forming a first flow sub-channel; two adjacent second connecting ribs and two adjacent first connecting ribs forming a second flow sub-channel, and the second flow sub-channel being isolated from the first flow sub-channel.

[0015] In some embodiments, the second connecting rib includes a third connecting segment and a fourth connecting segment connected to the third connecting segment, the third connecting segment being connected to the first connecting rib, and the width of the third connecting segment being greater than the width of the fourth connecting segment.

[0016] In some embodiments, the main body and the protective mesh cover are integrally formed.

[0034] Please see Figure 1 , Figure 2 and Figure 3 The heat dissipation assembly 100 of this utility model embodiment includes a main body 10 and a protective mesh cover 20. The main body 10 is provided with a first through hole 11; the protective mesh cover 20 is installed at the first through hole 11, and the protective mesh cover 20 protrudes from one side of the main body 10. A first guide channel 101 is formed at the edge of the protective mesh cover 20 and the first through hole 11. The orientation of the first guide channel 101 intersects with the orientation of the first through hole 11. The protective mesh cover 20 is provided with a second guide channel 102, and the orientation of the second guide channel 102 is the same as the orientation of the first through hole 11.

[0035] In the heat dissipation assembly 100 of this embodiment, the protective mesh cover 20 protrudes from one side of the main body 10 and forms a first flow channel 101 with the edge of the first through hole 11. Therefore, airflow can flow from the first through hole 11 to the first flow channel 101, which reduces the obstruction of airflow by the protective mesh cover 20, allowing airflow to pass through the protective mesh cover 20 more smoothly, thereby improving the heat dissipation effect and efficiency.

[0036] Meanwhile, the first guide channel 101 and the second guide channel 102 of the protective mesh cover 20 have different orientations. The protective mesh cover 20 can guide airflow from different directions at the same time, so that the airflow can not only flow from the first through hole 11 to the first guide channel 101, but also from the first through hole 11 to the second guide channel 102. This increases the flow path of the airflow, which helps to more effectively disperse and dissipate heat, and further improves the heat dissipation effect and heat dissipation efficiency.

[0037] Specifically, the heat dissipation component 100 is used to provide heat dissipation, and the heat dissipation component 100 can be used in electrical equipment 1000 (such as...). Figure 6 (As shown), such as inverters, transformers, etc.

[0038] The body portion 10 is a part of the heat dissipation assembly 100 used to support and fix other components, providing a stable mounting platform. The body portion 10 can be plate-shaped, cover-shaped, box-shaped, etc. For example, the body portion 10 is a heat dissipation plate.

[0039] The first through-hole 11 can be a through-hole that penetrates the body portion 10 along its thickness direction. The first through-hole 11 is used to allow airflow to pass through, thereby achieving the function of heat dissipation. The shape of the first through-hole 11 can be a regular shape such as a circle or a square, or it can be an irregular shape. The number of first through-holes 11 can be one or more, such as two, three, four or even more. For example, the number of first through-holes 11 is two, and the two first through-holes 11 can be arranged at intervals along the length direction of the body portion 10.

[0040] The protective mesh cover 20 is a mesh-like protective cover. It allows airflow and protects internal components by blocking dust and impurities. The protective mesh cover 20 can be installed at the first through hole 11 in a detachable manner, such as by threaded connection or snap-fit, or it can be installed at the first through hole 11 in a non-detachable manner, such as by bonding or welding.

[0041] The protective net cover 20 and the main body 10 can be a one-piece molded structure or a separate molded structure. In one embodiment, the protective net cover 20 and the main body 10 are separate molded structures. The separate molded structure can be replaced individually without replacing the whole, reducing maintenance costs. The protective net cover 20 and the main body 10 can be manufactured separately and then fixed by a detachable or non-detachable connection.

[0042] The protective mesh cover 20 and the main body 10 can be made of the same or different materials. For example, both the protective mesh cover 20 and the main body 10 can be made of aluminum alloy, which has good strength and thermal conductivity, and can meet the heat dissipation requirements.

[0043] The protective mesh cover 20 can be protruding from one side of the main body 10 by providing structures such as support columns and ribs. The protective mesh cover 20 does not flatly cover the first through hole 11, but rather protrudes from one side of the main body 10; in other words, the outer surface of the protective mesh cover 20 and the side of the main body 10 closest to the protective mesh cover 20 are not coplanar. Therefore, airflow can pass through the first guide channel 101 formed at the edges of the protective mesh cover 20 and the first through hole 11. There can be multiple first guide channels 101. The first guide channels 101 can be arranged at intervals along the edges of the first through hole 11. The first guide channels 101 can be located between the protective mesh cover 20 and the main body 10.

[0044] The number of second flow channels 102 can be formed by the mesh openings of the protective mesh cover 20. The orientation of the second flow channels 102 can be the same as or approximately the same as the orientation of the first through hole 11. The projected area of ​​the second flow channels 102 is smaller than the projected area of ​​the first through hole 11. The second flow channels 102 can be spaced apart from the main body 10.

[0045] The orientation of the first flow channel 101 refers to the direction perpendicular to the normal to the opening of the first flow channel 101. The orientation of the first via 11 refers to the direction perpendicular to the normal to the opening of the first via 11. The orientation of the second flow channel 102 refers to the direction perpendicular to the normal to the opening of the second flow channel 102.

[0046] Please see Figure 4 In related technologies, the heat dissipation assembly 100a includes a body portion 10a and a protective mesh cover 20a. The outer surface of the body portion 10a is coplanar with the side surface of the protective mesh cover 20a.

[0047] Simulation analysis using ANSYS Icepak software yielded the data shown in Table 1. Table 1 is a record of the flow resistance deviation of the heat dissipation component 100 of this invention and the heat dissipation component 100a of related technologies:

[0048] Table 1:

[0049]

[0050]

[0051] As can be seen from Table 1, the flow resistance of the heat dissipation component 100 of this embodiment is reduced by approximately 33% compared to the flow resistance of heat dissipation components 100 in related technologies. This indicates that the heat dissipation component 100 of this embodiment can ensure smooth airflow. Therefore, the data shows that the heat dissipation effect and efficiency of the heat dissipation component 100 of this embodiment are better. This is because the heat dissipation component 100 of this embodiment protrudes the protective mesh cover 20 on one side of the body portion 10 and forms a first flow guiding channel 101 with the edge of the first through hole 11. Therefore, airflow can flow from the first through hole 11 to the first flow guiding channel 101, which reduces the obstruction of the airflow by the protective mesh cover 20, allowing the airflow to pass through the protective mesh cover 20 more smoothly, thereby improving the heat dissipation effect and efficiency.

[0052] Meanwhile, the first guide channel 101 and the second guide channel 102 of the protective mesh cover 20 have different orientations. The protective mesh cover 20 can guide airflow from different directions at the same time, so that the airflow can not only flow from the first through hole 11 to the first guide channel 101, but also from the first through hole 11 to the second guide channel 102. This increases the flow path of the airflow, which helps to more effectively disperse and dissipate heat, and further improves the heat dissipation effect and heat dissipation efficiency.

[0053] Please see Figure 1 , Figure 2 and Figure 3 In some embodiments, the protective net cover 20 includes a protective section 21 and a reinforcing section 22. The protective section 21 is provided with a second flow channel 102 and protrudes from one side of the main body 10. The first end 220 of the reinforcing section 22 is connected to the protective section 21, and the second end 221 of the reinforcing section 22 is connected to the main body 10.

[0054] Thus, by strengthening the connection of section 22, the connection between the protective mesh cover 20 and the main body 10 is more secure, reducing the probability of the protective mesh cover 20 vibrating and generating noise, enhancing the overall strength of the protective mesh cover 20, and improving the durability of the heat dissipation component 100.

[0055] Specifically, the protective section 21 can be a mesh structure formed by multiple ribs. The protective section 21 may include multiple spaced-apart ribs. The second flow channel 102 can be formed through these spaced-apart ribs. The reinforcing section 22 can be a rib or support column connected to a specific area of ​​the protective section 21. The reinforcing section 22 can be straight or curved. The first end 220 of the reinforcing section 22 can be connected to the outer edge of the protective section 21. The second end 221 of the reinforcing section 22 can be connected to the wall of the first through hole 11.

[0056] The connection between the first end 220 of the reinforcing section 22 and the protective section 21 can be a detachable connection, such as a threaded connection or a snap-fit ​​connection; the connection between the first end 220 of the reinforcing section 22 and the protective section 21 can also be a non-detachable connection, such as an adhesive connection or a weld.

[0057] The first end 220 of the reinforcing section 22 can also be integrally formed with the protective section 21. An integrally formed structure is generally more robust because it has no assembly gaps, resulting in greater overall integrity and providing better compressive strength and stability. Alternatively, the first end 220 of the reinforcing section 22 can also be separately formed from the protective section 21. Separately formed structures can be replaced individually without replacing the entire section, reducing maintenance costs.

[0058] The connection between the second end 221 of the reinforcing section 22 and the body part 10 can be a detachable connection, such as a threaded connection or a snap-fit ​​connection; the connection between the second end 221 of the reinforcing section 22 and the body part 10 can also be a non-detachable connection, such as an adhesive connection or a weld.

[0059] The second end 221 of the reinforcing section 22 can also be integrally formed with the main body 10. An integrally formed structure is generally more robust because it has no assembly gaps, resulting in greater overall integrity and providing better compressive strength and stability. Alternatively, the second end 221 of the reinforcing section 22 can also be separately formed from the main body 10. Separately formed structures can be replaced individually without replacing the entire section, reducing maintenance costs.

[0060] The reinforcing segment 22 is spaced apart from the main body 10. The distance between the reinforcing segment 22 and the main body 10 can be set as needed. For example, the minimum distance between the reinforcing segment 22 and the main body 10 can be 5mm. The width of the reinforcing segment 22 can be set as needed. For example, the width of the cross-section of the reinforcing segment 22 can be 2mm.

[0061] Please see Figure 1 , Figure 2 and Figure 3 In some embodiments, there are multiple reinforcing sections 22, which are spaced apart circumferentially along the protective section 21.

[0062] Thus, by arranging multiple reinforcing sections 22 at circumferential intervals along the protective section 21, the reinforcing sections 22 can strengthen the protective section 21 in multiple areas, and the load acting on the protective section 21 can be more evenly distributed. This helps to reduce the concentrated stress borne by a single reinforcing section 22, thereby improving the durability and reliability of the entire protective mesh cover 20.

[0063] Specifically, the number of reinforcing segments 22 can be two, three, four, or even more. For example, there can be four reinforcing segments 22, with two reinforcing segments 22 located on one side of the protective segment 21 and the other two on the opposite side of the protective segment 21. The four reinforcing segments 22 located on both sides of the protective segment 21 are symmetrically arranged about the central axis of the protective segment 21. This can evenly support the protective segment 21 and reduce the possibility of vibration in the protective segment 21.

[0064] Please see Figure 1 and Figure 5 In some embodiments, the protective section 21 further includes a first connecting rib 210 and a second connecting rib 211. The first connecting rib 210 is in the shape of a ring, and there are multiple first connecting ribs 210. The multiple first connecting ribs 210 are arranged at intervals with the same center. The second connecting rib 211 connects the multiple first connecting ribs 210.

[0065] Thus, by setting the second connecting rib 211 to connect multiple first connecting ribs 210 arranged at intervals with the same center, the structural strength of the protective section 21 can be enhanced, thereby improving the deformation resistance and impact resistance of the protective section 21, and thus improving the durability of the entire heat dissipation assembly 100. At the same time, this connection method can play a role in safety protection and can reduce the probability of external dust and impurities passing through the first through hole 11.

[0066] Specifically, the multiple first connecting ribs 210 can form a radial or annular structure. The second connecting rib 211 connects the multiple first connecting ribs 210, which can fix the first connecting ribs 210 together and enhance the structural strength of the entire protective section 21. The second connecting rib 211 can be curved or straight.

[0067] The distance between two adjacent first connecting ribs 210 can be equal or unequal. For example, multiple first connecting ribs 210 can be arranged at equal intervals around the same center.

[0068] The second connecting rib 211 can be manufactured integrally with the first connecting rib 210. This protective section 21 has higher structural strength because there is no assembly gap between the second connecting rib 211 and the first connecting rib 210, resulting in stronger overall integrity and better compressive strength and stability.

[0069] Please see Figure 1 and Figure 5 In some embodiments, there are multiple reinforcing segments 22, which are spaced apart circumferentially along the protective segment 21. The first connecting rib 210 includes an outer connecting rib 2100, which is disposed on the outermost periphery of the multiple first connecting ribs 210. The outer connecting rib 2100 includes a first connecting segment 2101 and a second connecting segment 2102 connected to the first connecting segment 2101. The first connecting segment 2101 connects the first ends 220 of two adjacent reinforcing segments 22, and the width of the first connecting segment 2101 is greater than the width of the second connecting segment 2102.

[0070] Thus, the width of the first connecting segment 2101 connecting the outer connecting rib 2100 and the reinforcing segment 22 is relatively large, which makes the connection between the protective segment 21 and the reinforcing segment 22 more robust and reduces the probability of connection failure between the protective segment 21 and the reinforcing segment 22. Furthermore, since the first guiding channel 101 is formed at the edge of the protective mesh cover 20 and the first through hole 11, the larger width of the first connecting segment 2101 also provides better resistance to deformation and impact, thereby improving the durability of the entire heat dissipation assembly 100.

[0071] Specifically, the outer connecting rib 2100 is a connecting rib disposed on the outermost periphery of the plurality of first connecting ribs 210, used to connect the reinforcing section 22. The first connecting section 2101 is a structure on the outer connecting rib 2100 used to connect the second connecting section 2102 and the reinforcing section 22. The second connecting section 2102 is a structure on the outer connecting rib 2100 used to connect two adjacent first connecting sections 2101.

[0072] The width of the first connecting segment 2101 refers to the width of the cross-section of the first connecting segment 2101. The width of the second connecting segment 2102 refers to the width of the cross-section of the second connecting segment 2102.

[0073] The first connecting segment 2101 can be manufactured integrally with the second connecting segment 2102. This results in a higher structural strength for the outer connecting rib 2100 because there are no assembly gaps between the first connecting segment 2101 and the second connecting segment 2102, resulting in stronger overall integrity and better compressive strength and stability.

[0074] The first connecting segment 2101 and the second connecting segment 2102 are in Figure 5 The figures are separated by dashed lines, but it should be noted that the dashed lines in the figures are only for illustrative purposes and should not be construed as limiting the embodiments of this utility model.

[0075] Please see Figure 1 and Figure 5 In some embodiments, the second connecting rib 211 passes through the center of the first connecting rib 210.

[0076] Thus, the second connecting rib 211 passes through the center of the first connecting rib 210, forming a symmetrical structure. This enhances the mutual support between the first connecting ribs 210, helps to evenly distribute stress, and improves the overall connection strength of the protective section 21.

[0077] Please see Figure 1 and Figure 5 In some embodiments, there are multiple second connecting ribs 211, which intersect at the center of the first connecting rib 210, and the second connecting ribs 211 and the first connecting rib 210 form a second flow channel 102.

[0078] Thus, the intersecting design of multiple second connecting ribs 211 at the center allows the second airflow channel 102 to have multiple areas for airflow passage. This helps optimize the airflow distribution in the second airflow channel 102, making the airflow more uniform as it passes through the first connecting ribs 210 and the second connecting ribs 211, reducing mutual interference between airflows, and thereby improving heat dissipation effect and efficiency. Furthermore, the first connecting ribs 210 and the second connecting ribs 211 can have more connection points, which can improve the connection strength between the first connecting ribs 210 and the second connecting ribs 211.

[0079] Specifically, the number of second connecting ribs 211 can be two, three, four, or even more. For example, the number of second connecting ribs 211 is two, and the two second connecting ribs 211 are in an "X" shape. This can ensure the connection strength between the first connecting rib 210 and the second connecting rib 211 while using less material to manufacture the second connecting ribs 211, thereby reducing the overall manufacturing cost of the heat dissipation component 100.

[0080] There may be gaps between the multiple second connecting ribs 211 and the first connecting rib 210. These gaps together form the second flow channel 102.

[0081] Please see Figure 1 and Figure 5 In some embodiments, the second flow channel 102 includes a first flow sub-channel 1020 and a second flow sub-channel 1021. Two adjacent second connecting ribs 211 and the innermost first connecting rib 210 form the first flow sub-channel 1020; two adjacent second connecting ribs 211 and two adjacent first connecting ribs 210 form the second flow sub-channel 1021, and the second flow sub-channel 1021 is isolated from the first flow sub-channel 1020.

[0082] Thus, by subdividing the second flow channel 102 into a first flow sub-channel 1020 and a second flow sub-channel 1021, and isolating them from each other, airflow can be managed and guided more effectively. This design allows the heat dissipation component 100 to guide airflow from multiple independent channels simultaneously, increasing the flow path of the airflow and reducing mutual interference between airflows, thereby improving heat dissipation effect and efficiency.

[0083] Specifically, the second flow guide channel 1021 can be arranged circumferentially around the first flow guide channel 1020. The projected area of ​​the second flow guide channel 1021 can be larger than that of the first flow guide channel 1020, so that the second flow guide channel 1021 can allow more airflow to pass through compared to the first flow guide channel 1020. The first flow guide channel 1020 and the second flow guide channel 1021 can be isolated by the first connecting rib 210.

[0084] Please see Figure 1 and Figure 5 In some embodiments, the second connecting rib 211 includes a third connecting segment 2110 and a fourth connecting segment 2111 connected to the third connecting segment 2110. The third connecting segment 2110 is connected to the first connecting rib 210, and the width of the third connecting segment 2110 is greater than the width of the fourth connecting segment 2111.

[0085] Thus, since the width of the third connecting segment 2110 on the second connecting rib 211 and the first connecting rib 210 is relatively large, this reduces local stress concentration, improves the strength and stability of the connection point, and thereby enhances the structural stability of the entire heat dissipation assembly 100.

[0086] Specifically, the width of the third connecting segment 2110 refers to the width of the cross-section of the third connecting segment 2110. The width of the fourth connecting segment 2111 refers to the width of the cross-section of the fourth connecting segment 2111.

[0087] The third connecting segment 2110 and the fourth connecting segment 2111 are in Figure 5 The figures are separated by dashed lines, but it should be noted that the dashed lines in the figures are only for illustrative purposes and should not be construed as limiting the embodiments of this utility model.

[0088] In some embodiments, the main body 10 and the protective mesh cover 20 are integrally formed.

[0089] Thus, the one-piece molded structure makes it easier to install and disassemble the heat dissipation component 100, eliminating the need to separately handle the main body 10 and the protective mesh cover 20. This reduces the number of parts to be disassembled, thereby reducing maintenance difficulty and saving time and manpower. With the main body 10 and the protective mesh cover 20 integrated as a single unit, the structure is more stable and can better withstand external impacts and vibrations.

[0090] Specifically, the main body 10 and the protective net cover 20 can be integrally formed using a stamping process. During the stamping process, dimensional accuracy can be strictly controlled to ensure a firm bond between the main body 10 and the protective net cover 20, and to ensure that the surface of the integrally formed structure after stamping is smooth and free of obvious defects.

[0091] Please see Figure 6 and Figure 7 The electrical equipment 1000 of this utility model includes a heat dissipation component 100 and a heat dissipation fan 200 as described in any of the above embodiments; the heat dissipation fan 200 is provided corresponding to the first through hole 11 and is provided on the side of the main body 10 away from the protective mesh cover 20.

[0092] Thus, the protective mesh cover 20 reduces the probability of dust and impurities entering the electrical equipment 1000, thereby protecting the cooling fan 200 and the internal components of the electrical equipment 1000. This reduces the risk of malfunctions caused by dust accumulation or foreign object interference, and also reduces the possibility of safety accidents caused by accidental contact with the cooling fan 200, thus improving the safety of the electrical equipment 1000. Furthermore, since the electrical equipment 1000 includes the aforementioned heat dissipation component 100, the electrical equipment 1000 at least includes all the beneficial effects of the aforementioned heat dissipation component 100, which will not be elaborated further here.

[0093] Specifically, electrical equipment 1000 can be devices such as inverters and transformers. For example, electrical equipment 1000 is an inverter. Inverters are used to convert direct current (DC) to alternating current (AC), and they generate a large amount of heat during operation. Cooling fans 200 can dissipate heat from the inverter, thereby ensuring its normal operation.

[0094] The cooling fan 200 is a component that achieves heat dissipation by controlling airflow. The size and power of the cooling fan 200 can be selected according to the heat dissipation requirements and space constraints of the electrical equipment 1000. There can be one or more cooling fans 200. Each cooling fan 200 can be configured to correspond one-to-one with the first through-hole 11.

[0095] During assembly, the cooling fan 200 can be detachably mounted on the body 10 via threaded connections, snap-fit ​​connections, or other detachable methods. Alternatively, the cooling fan 200 can be non-detachably mounted on the body 10 via welding, riveting, or other non-detachable methods. During installation, ensure the cooling fan 200 is accurately positioned and securely installed. The gap between the cooling fan 200 and the protective mesh cover 20 should be controlled within a reasonable range to ensure smooth airflow.
