Description

Technical Field

[0001] The present application relates to the technical field of radiators, and in particular to a heat dissipation component and a power unit cabinet. Background Art

[0002] With the improvement of industrial automation, high-voltage inverters have been widely used in power, metallurgy, petrochemical and other industries. Among them, the power unit, as one of the core components of the high-voltage inverter, will generate a lot of heat when working. If it cannot be dissipated in time and effectively, it will affect the working performance and service life of the power unit.

[0003] In the related art, due to the unreasonable design of the heat sink structure, the heat sink used in the power unit of the high-voltage inverter has the problem of poor heat dissipation effect. Utility Model Content

[0004] The present application aims to solve one of the technical problems existing in the prior art or related technology.

[0005] To this end, a first aspect of the present application proposes a heat dissipation component.

[0006] A second aspect of the present application provides a power unit cabinet.

[0007] In view of this, according to the first aspect of the present application, a heat dissipation component is proposed, including: a substrate; at least two first fins, arranged on the substrate, and at least two first fins are arranged side by side on the substrate; a second fin, arranged on the substrate, and the second fin is located on the peripheral side of the at least two first fins; a cover plate, connected to the second fin, and at least two first fins are located between the substrate and the cover plate, and the cover plate and the second fin enclose a heat dissipation outlet.

[0008] In this technical solution, the heat dissipation assembly includes a base plate and a cover plate, and at least two first fins and a second fin between the base plate and the cover plate, wherein the second fin is enclosed around the at least two first fins, the cover plate and the second fin are connected to form a cover structure, and the cover structure is buckled on the base plate and can cover the at least two first fins. A heat dissipation port is provided on the cover structure formed by the connection of the cover plate and the second fin, and the heat dissipation port is used to dissipate heat from the first fin and the second fin.

[0009] Specifically, the heat dissipation component is arranged in the power unit cabinet, and the heat dissipation component is arranged in contact with the power unit and the base plate in the power unit cabinet. The heat generated by the power unit during operation is transferred to the first fin and the second fin through the base plate, and the outside air flows through the first fin and the second fin through the heat dissipation port to take away the heat of the first fin and the second fin. Among them, the base plate, the cover plate, the first fin and the second fin play a role in heat dissipation together, and the second fin and the cover plate enclose the first fin, and can also protect and prevent dust from the first fin.

[0010] In this technical solution, at least two first fins are arranged side by side, that is, the extension direction of at least two first fins is the same, and at least two first fins are arranged at intervals, and the first fin and the second fin are arranged at intervals. Air can pass through the interval between at least two first fins, and through the interval between the first fin and the second fin, and flow through the first fin and the second fin, thereby dissipating the heat of the first fin.

[0011] In this technical solution, the cover plate is connected to the second fin to form a cover structure, and the cover structure is buckled on the base plate to cover the first fin, thereby playing a dust-proof role for at least two first fins, avoiding excessive dust from entering between at least two first fins and causing blockage of air flow, thereby ensuring the overall heat dissipation performance of the heat dissipation assembly.

[0012] In this technical solution, the first fin and the second fin have different heights, and the height is the size of the first fin and the second fin in the direction perpendicular to the substrate. The height of the second fin is higher than the height of the first fin, so that a gap is formed between the first fin and the cover, increasing the contact area and contact time between the air flowing into the heat dissipation component through the heat dissipation port and the first fin, further improving the heat dissipation performance of the first fin in the heat dissipation component.

[0013] In the technical solution of the present application, a plurality of first fins are arranged side by side between the base plate and the cover plate, and second fins are arranged on the peripheral sides of the plurality of first fins, so that the cover plate, the base plate, the first fins and the second fins can jointly dissipate heat for the power unit in the power unit cabinet, and the second fins are connected to the cover plate, so that the second fins and the cover body enclose the first fins, thereby protecting and preventing dust from the first fins, and the cover body and the second fins enclose a heat dissipation port, and the air flowing in through the heat dissipation port can flow through the first fins and the second fins, thereby improving the heat exchange efficiency of the air to the first fins and the second fins, and improving the heat dissipation effect of the first fins and the second fins on the heat dissipation component.

[0014] In some technical solutions, optionally, the heat dissipation outlet includes a first air outlet; wherein the second fin avoids the first side of at least two first fins, and the cover plate and the second fin enclose the first air outlet on the first side of at least two first fins.

[0015] In this technical solution, the first side of at least two first fins is the outflow side of the air flowing through the first fins. It should be noted that when the air flows through the first fins, the air can flow along the extension direction of the first fins and the second fins.

[0016] In this technical solution, the second fin avoids the first side of the first fin, that is, the second fin does not enclose the first side of the first fin, so one side of the first fin is exposed, and the cover plate and the second fin enclose the first air outlet. The first air outlet is the air outlet of the heat dissipation component, that is, after the air flows through the first fin and the second fin, it can flow out of the heat dissipation component through the first air outlet.

[0017] In the technical solution of the present application, the second fin is arranged to avoid the first side of the first fin, so that the first air outlet formed by the second fin and the cover plate is located on the first side of the first fin. During the heat dissipation process of the heat dissipation assembly, air flows through the first fin and the second fin, and then flows out of the heat dissipation assembly through the first air outlet to dissipate heat for the first fin and the second fin.

[0018] In some technical solutions, optionally, at least two first fins are spaced apart from the first air outlet.

[0019] In this technical solution, the first air outlet formed by the cover plate and the second fin is spaced apart from the first fin, that is, the first fin does not extend to the first air outlet. Specifically, the first side of the first fin is extended in the direction of the first air outlet and extends to a position at a distance from the first air outlet, ensuring that the cover plate can completely cover at least two first fins, improving the protective effect of the cover plate on the first fins, and reducing the volume and weight of at least two first fins, thereby reducing the mass and volume of the heat dissipation component.

[0020] In the technical solution of the present application, the first side of the first fin extends toward the first air outlet, and the edge of the first side of the first fin is spaced apart from the first air outlet, so that the cover plate can completely cover the first fin, thereby improving the protective and dust-proof effect of the cover plate on the first fin, and reducing the volume and weight of the first fin, thereby reducing the overall weight of the heat dissipation assembly, making it easier to subsequently install the heat dissipation assembly into the power unit cabinet.

[0021] In some technical solutions, optionally, in the first direction, the distance between at least two first fins and the first air outlet is a first spacing;

[0022] The length of each of the at least two first fins in the first direction is a first length;

[0023] The first spacing is greater than or equal to 1 / 6 of the first length and less than or equal to 1 / 3 of the first length.

[0024] In this technical solution, the first direction is the extension direction of the first fin, and also the air flow direction when the air flows through the first fin. In the first direction, at least two first fins are spaced apart from the first air outlet, and the spacing between at least two first fins and the first air outlet is the first spacing.

[0025] In this technical solution, the first length is the size of at least two first fins in the extension direction, that is, the first fins of the first length are in contact with the substrate, and the heat conducted by the substrate is dissipated through the first fins of the first length.

[0026] In this technical solution, the first spacing is set to be greater than or equal to 1 / 6 of the first length, so that there is a sufficient spacing between the first fin and the first air outlet, so as to reduce the sufficient volume and mass of at least two first fins, further reducing the volume and weight of the heat dissipation assembly, and the first spacing allows the air flowing through the first fin to have enough space to flow, avoiding the heat of the first fin from accumulating at the first air outlet. The first spacing is set to be less than or equal to 1 / 3 of the first length, so that the first fin has a sufficient length, ensuring the contact area between the first fin and the substrate, so as to ensure the heat dissipation efficiency of the heat dissipation assembly to the power unit in the power unit cabinet.

[0027] In the technical solution of the present application, by setting a first spacing between at least two first fins and the first air outlet in the first direction, and setting the first spacing to be greater than or equal to 1 / 6 of the first length of the first fin, and setting the first spacing to be less than or equal to 1 / 3 of the first length of the first fin, the volume and weight of the heat dissipation assembly are further reduced, and a sufficient first spacing allows enough space for the air flowing through the first fin to flow, avoiding accumulation of heat from the first fin at the first air outlet position, and making the first fin have a sufficient length to ensure the contact area between the first fin and the substrate, so as to ensure the heat dissipation efficiency of the heat dissipation assembly to the power unit in the power unit cabinet.

[0028] In some technical solutions, optionally, the heat dissipation outlet further includes a second air outlet, the second air outlet is located on a side of at least two first fins facing away from the substrate, and the first air outlet and the second air outlet are spaced apart.

[0029] In this technical solution, the second air port is the air inlet of the heat dissipation assembly, and the second air port is on the side of at least two first fins facing away from the substrate, that is, the second air port is arranged on the cover plate. The second air port is arranged at a distance from the first air port, and the air can flow through the first fin and the second fin in the process of air entering the heat dissipation assembly through the second air port as the air inlet and being discharged from the heat dissipation assembly through the first air port as the air outlet.

[0030] In the technical solution of the present application, the heat dissipation outlet includes a first air outlet and a second air outlet, and the first air outlet serves as an air inlet and the second air outlet serves as an air outlet. The second air outlet is arranged at the cover plate position, so that the air can flow toward the first fin and the second fin along the cover plate direction, and the first air outlet is arranged at intervals from the second air outlet, which can increase the contact area between the air and the first fin and the second fin in the process of air flowing through the second air outlet and the first air outlet, thereby avoiding heat accumulation on the first fin and the second fin and improving the heat exchange efficiency between the air and the first fin and the second fin.

[0031] In some technical solutions, optionally, the cover plate, at least two first fins and the second fins enclose a heat dissipation duct, wherein the heat dissipation duct is connected to the first air outlet and the second air outlet.

[0032] In this technical solution, the cover plate, the second fin, and at least two first fins in the heat dissipation assembly can enclose to form a heat dissipation duct. After the air enters the heat dissipation assembly through the second air outlet, it can flow through the first fin and the second fin through the heat dissipation duct and flow out of the heat dissipation assembly through the first air outlet.

[0033] Specifically, at least two first fins are spaced apart, and the first fin and the second fin are spaced apart, and the cover plate covers the top of the first fin and the second fin, so the interval between at least two first fins, the interval between the first fin and the second fin, and the interval between the first fin and the cover plate together form a heat dissipation duct, so that when air flows through the heat dissipation duct, it can fully contact the cover plate, the first fin and the second fin, thereby improving the heat exchange efficiency.

[0034] In the technical solution of the present application, since the cover plate is connected to the second fin, the cover plate, the substrate, the second fin and the first fin can jointly serve as a heat dissipation structure to dissipate the heat transferred from the substrate. The cover plate, the second fin and the first fin are enclosed to form a heat dissipation duct. During the process of air flowing through the heat dissipation duct, it can fully contact the cover plate, the second fin and the first fin, thereby improving the heat exchange efficiency between the air and the cover plate, the second fin and the first fin.

[0035] In some technical solutions, optionally, the base plate includes at least two first slots and a second slot;

[0036] Among them, at least two first fins are welded to the base plate through at least two first slots, and the at least two first slots correspond to the at least two first fins one by one, and the second fins are welded to the base plate through the second slots.

[0037] In this technical solution, a first slot for inserting a first fin and a second slot for inserting a second fin are provided on the base plate. Specifically, the first slots are arranged at intervals, so that the first fins are also arranged at intervals when they are arranged on the base plate through the first slots, and the second slots are arranged at intervals from adjacent first slots, so that the second fins inserted on the base plate are arranged at intervals from adjacent first fins.

[0038] Specifically, after the first fin is plugged into the base plate through the first slot and the second fin is plugged into the base plate through the second slot, the first fin and the second fin are fixedly connected to the base plate by welding to improve the heat conduction efficiency between the base plate and the first fin and the second fin.

[0039] In the technical solution of the present application, by setting a first slot and a second slot on the substrate, the first fin and the second fin can be pre-installed, and the installed first fin and the second fin are welded to the substrate through the first slot and the second slot, thereby improving the thermal conductivity between the first fin and the second fin, thereby improving the heat dissipation efficiency of the heat dissipation assembly.

[0040] In some technical solutions, the second fin and the cover plate are an integrated structure.

[0041] In the technical solution of the present application, the second fin and the cover plate are integrally formed, so that the cover plate and the second fin can form a cover structure, and the cover structure is buckled on the base plate to cover and protect the first fin and facilitate the overall installation of the second fin and the cover body.

[0042] In some technical solutions, an anodized film is provided on at least two first fins, the second fin, the base plate and the cover plate.

[0043] In the technical solution of the present application, by anodizing at least two first fins, a second fin, a substrate and a cover plate, the surfaces of the first fins, the second fins, the substrate and the cover plate are covered with an anodized film, thereby improving the thermal conductivity and corrosion resistance of the heat dissipation component.

[0044] According to the second aspect of the present application, a power unit cabinet is proposed, comprising: a cabinet; a heat dissipation assembly arranged in the cabinet; a power unit arranged in the cabinet, wherein the power unit is arranged in contact with a substrate of the heat dissipation assembly. The heat dissipation assembly is a heat dissipation assembly in any of the above technical solutions, and thus has the beneficial technical effects of the heat dissipation assembly in any of the above technical solutions, which will not be described in detail here.

[0054] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present application is not limited to the specific embodiments disclosed below.

[0055] Refer to the following Figures 1 to 4 A heat dissipation assembly and a power unit cabinet according to some embodiments of the present application are described.

[0056] According to one embodiment of the present application, Figure 1 One of the structural schematic diagrams of the heat dissipation assembly provided in some embodiments of the present application is shown, such as Figure 1 As shown, the heat dissipation component 100 includes: a substrate 110; at least two first fins 120, which are arranged on the substrate 110, and at least two first fins 120 are arranged side by side on the substrate 110; second fins 130, which are arranged on the substrate 110, and the second fins 130 are located on the peripheral side of at least two first fins 120; a cover plate 140, which is connected to the second fins 130, and at least two first fins 120 are located between the substrate 110 and the cover plate 140, and the cover plate 140 and the second fins 130 enclose a heat dissipation outlet 150.

[0057] In this embodiment, the heat dissipation assembly 100 includes a substrate 110 and a cover plate 140, and at least two first fins 120 and a second fin 130 between the substrate 110 and the cover plate 140, wherein the second fin 130 is enclosed around the at least two first fins 120, and the cover plate 140 and the second fin 130 are connected to form a cover structure, which is buckled on the substrate 110 and can cover the at least two first fins 120. A heat dissipation port 150 is provided on the cover structure formed by connecting the cover plate 140 and the second fin 130, and the heat dissipation port 150 is used to dissipate heat from the first fin 120 and the second fin 130.

[0058] Specifically, the heat dissipation assembly 100 is arranged in the power unit cabinet, and the heat generated by the power unit during operation is conducted to the first fin 120 and the second fin 130 through the base plate 110, and the outside air flows through the first fin 120 and the second fin 130 through the heat dissipation port 150, and takes away the heat of the first fin 120 and the second fin 130. Among them, the base plate 110, the cover plate 140, the first fin 120 and the second fin 130 play a role in heat dissipation, and the second fin 130 and the cover plate 140 enclose the first fin 120, and can also protect and prevent dust from the first fin 120.

[0059] Exemplarily, a fan assembly is disposed in the power unit cabinet, and the fan assembly can drive air outside the power unit cabinet to flow through the first fin 120 and the second fin 130 through the heat dissipation opening 150 , thereby dissipating heat from the first fin 120 and the second fin 130 .

[0060] In this embodiment, at least two first fins 120 are arranged side by side, that is, the extension direction of at least two first fins 120 is the same, and at least two first fins 120 are arranged at intervals, and the first fin 120 and the second fin 130 are arranged at intervals. Air can flow through the intervals between at least two first fins 120, and through the intervals between the first fin 120 and the second fin 130, thereby dissipating the heat of the first fin 120.

[0061] In this embodiment, the cover plate 140 is connected to the second fin 130 to form a cover structure, which is buckled on the substrate 110 to cover the first fin 120, thereby providing dust protection for at least two first fins 120, preventing excessive dust from entering between at least two first fins 120 and causing blockage of air flow, thereby ensuring the overall heat dissipation performance of the heat dissipation assembly 100.

[0062] Exemplarily, the cover plate 140 and the second fin 130 are integrally formed.

[0063] In this embodiment, the first fin 120 and the second fin 130 have different heights, and the height is the size of the first fin 120 and the second fin 130 in a direction perpendicular to the substrate 110. The height of the second fin 130 is higher than the height of the first fin 120, so that a gap is formed between the first fin 120 and the cover plate 140, thereby increasing the contact area and contact time between the air flowing into the heat dissipation component 100 through the heat dissipation port 150 and the first fin 120, and further improving the heat dissipation performance of the first fin 120 in the heat dissipation component 100.

[0064] In the embodiment of the present application, by arranging multiple first fins 120 side by side between the substrate 110 and the cover plate 140, and second fins 130 are arranged on the peripheral sides of the multiple first fins 120, the cover plate 140, the substrate 110, the first fins 120 and the second fins 130 can jointly dissipate heat for the power unit in the power unit cabinet, and the second fins 130 are connected to the cover plate 140, so that the second fins 130 and the cover plate 140 enclose the first fins 120, thereby protecting and dustproofing the first fins 120, and the cover plate 140 and the second fins 130 enclose a heat dissipation port 150, and the air flowing in through the heat dissipation port 150 can flow through the first fins 120 and the second fins 130, thereby improving the heat exchange efficiency of the air to the first fins 120 and the second fins 130, and improving the heat dissipation effect of the first fins 120 and the second fins 130 on the heat dissipation assembly 100.

[0065] In some embodiments, optionally, the heat dissipation outlet 150 includes a first air outlet 152 ; wherein the second fin 130 avoids the first side of at least two first fins 120 , and the cover plate 140 and the second fin 130 enclose the first air outlet 152 on the first side of at least two first fins 120 .

[0066] In this embodiment, the first sides of at least two first fins 120 are outflow sides of the air flowing through the first fins 120. It should be noted that when the air flows through the first fins 120, the air can flow along the extension direction of the first fins 120 and the second fins 130.

[0067] In this embodiment, the second fin 130 avoids the first side of the first fin 120, that is, the second fin 130 does not enclose the first side of the first fin 120, so one side of the first fin 120 is in an exposed state, and the cover plate 140 and the second fin 130 enclose the first air outlet 152. The first air outlet 152 is the air outlet of the heat dissipation component 100, that is, after the air flows through the first fin 120 and the second fin 130, it can flow out of the heat dissipation component 100 through the first air outlet 152.

[0068] like Figure 1 As shown, Figure 1Arrow A in illustrative diagram shows a first side of the first fin 120 , and the first air outlet 152 is located on the first side of the first fin 120 .

[0069] In the embodiment of the present application, the second fin 130 is arranged to avoid the first side of the first fin 120, so that the first air outlet 152 formed by the second fin 130 and the cover plate 140 is located on the first side of the first fin 120. When the heat dissipation assembly 100 is dissipating heat, the air flows through the first fin 120 and the second fin 130, and then flows out of the heat dissipation assembly 100 through the first air outlet 152 to dissipate heat for the first fin 120 and the second fin 130.

[0070] like Figure 1 As shown, in some embodiments, optionally, at least two first fins 120 are spaced apart from the first air outlet 152 .

[0071] In this embodiment, the first air outlet 152 formed by the cover plate 140 and the second fin 130 is spaced apart from the first fin 120, that is, the first fin 120 does not extend to the first air outlet 152. Specifically, the first side of the first fin 120 is extended in the direction of the first air outlet 152, and extends to a position at a distance from the first air outlet 152, ensuring that the cover plate 140 can completely cover at least two first fins 120, improving the protective effect of the cover plate 140 on the first fins 120, and reducing the volume and weight of at least two first fins 120, thereby reducing the mass and volume of the heat dissipation assembly 100.

[0072] In the embodiment of the present application, the first side of the first fin 120 extends toward the first air outlet 152, and the edge of the first side of the first fin 120 is spaced apart from the first air outlet 152, so that the cover plate 140 can completely cover the first fin 120, thereby improving the protection and dustproof effect of the cover plate 140 on the first fin 120, and reducing the volume and weight of the first fin 120, thereby reducing the overall weight of the heat dissipation assembly 100, and facilitating the subsequent installation of the heat dissipation assembly 100 into the power unit cabinet.

[0073] Figure 2 FIG. 2 shows a second structural schematic diagram of a heat dissipation assembly 100 provided in some embodiments of the present application. Figure 2 As shown, in some embodiments, optionally, in the first direction, the distance between at least two first fins 120 and the first air outlet 152 is a first spacing;

[0074] The length of each of the at least two first fins 120 in the first direction is a first length;

[0075] The first spacing is greater than or equal to 1 / 6 of the first length and less than or equal to 1 / 3 of the first length.

[0076] In this embodiment, the first direction is the extension direction of the first fin 120, and is also the air flow direction when the air flows through the first fin 120. In the first direction, at least two first fins 120 are spaced apart from the first air outlet 152, and the spacing between at least two first fins 120 and the first air outlet 152 is the first spacing.

[0077] like Figure 2 As shown, Figure 2 The arrow B in shows the first direction, and the first spacing L1 is the distance between at least two first fins 120 and the first air outlet 152 .

[0078] In this embodiment, the first length is the size of at least two first fins 120 in the extension direction, that is, the first fins 120 of the first length are in contact with the substrate 110, and the heat conducted by the substrate 110 is dissipated through the first fins 120 of the first length.

[0079] like Figure 2 As shown, the first length L2 is the length of at least two first fins 120 in the first direction, and the lengths of at least two first fins 120 are the same.

[0080] In this embodiment, the first spacing is set to be greater than or equal to 1 / 6 of the first length, so that there is a sufficient spacing between the first fin 120 and the first air outlet 152, so as to reduce the volume and mass of at least two first fins 120, further reducing the volume and weight of the heat dissipation assembly 100, and the sufficient first spacing allows the air flowing through the first fin 120 to have enough space to flow, avoiding the heat of the first fin 120 from accumulating at the position of the first air outlet 152. The first spacing is set to be less than or equal to 1 / 3 of the first length, so that the first fin 120 has a sufficient length, ensuring the contact area between the first fin 120 and the base plate 110, so as to ensure the heat dissipation efficiency of the heat dissipation assembly 100 to the power unit in the power unit cabinet.

[0081] Exemplarily, the first length ranges from 300 mm to 1000 mm.

[0082] In an embodiment of the present application, by setting a first spacing between at least two first fins 120 and the first air outlet 152 in the first direction, and setting the first spacing to be greater than or equal to 1 / 6 of the first length of the first fin 120, and setting the first spacing to be less than or equal to 1 / 3 of the first length of the first fin 120, the volume and weight of the heat dissipation assembly 100 are further reduced, and the first spacing allows sufficient space for the air flowing through the first fin 120 to flow, thereby avoiding accumulation of heat from the first fin 120 at the first air outlet 152, and allowing the first fin 120 to have a sufficient length to ensure the contact area between the first fin 120 and the substrate 110, thereby ensuring the heat dissipation efficiency of the heat dissipation assembly 100 for the power unit in the power unit cabinet.

[0083] like Figure 1 As shown, in some embodiments, optionally, the heat dissipation vent 150 further includes a second vent 154 , which is located on a side of at least two first fins 120 facing away from the substrate 110 , and the first vent 152 and the second vent 154 are spaced apart.

[0084] In this embodiment, the second air vent 154 is an air inlet of the heat dissipation assembly 100, and the second air vent 154 is disposed on a side of at least two first fins 120 facing away from the substrate 110, that is, the second air vent 154 is disposed on the cover plate 140. The second air vent 154 is spaced apart from the first air vent 152, and the air can flow through the first fin 120 and the second fin 130 during the process of the air entering the heat dissipation assembly 100 through the second air vent 154 as an air inlet and being discharged from the heat dissipation assembly 100 through the first air vent 152 as an air outlet.

[0085] Exemplarily, the second air outlet 154 and the first air outlet 152 are respectively located at the two ends of the first fin 120, so that when the air flows through the first air outlet 152 and the second air outlet 154 in sequence, it can flow through the complete first fin 120 and the second fin 130, thereby improving the heat exchange efficiency between the air and the first fin 120 and the second fin 130.

[0086] In the embodiment of the present application, the heat dissipation outlet 150 includes a first air outlet 152 and a second air outlet 154, and the first air outlet 152 serves as an air inlet, and the second air outlet 154 serves as an air outlet. The second air outlet 154 is arranged at the position of the cover plate 140, so that the air can flow along the direction of the cover plate 140 toward the first fin 120 and the second fin 130, and the first air outlet 152 and the second air outlet 154 are arranged at intervals, which can increase the contact area between the air and the first fin 120 and the second fin 130 during the process of the air flowing through the second air outlet 154 and the first air outlet 152, thereby avoiding heat accumulation on the first fin 120 and the second fin 130 and improving the heat exchange efficiency between the air and the first fin 120 and the second fin 130.

[0087] like Figure 1 and Figure 2 As shown, in some embodiments, optionally, the cover plate 140 , at least two first fins 120 and the second fin 130 enclose a heat dissipation duct 170 , wherein the heat dissipation duct 170 is connected to the first air outlet 152 and the second air outlet 154 .

[0088] In this embodiment, the cover plate 140, the second fins 130, and at least two first fins 120 in the heat dissipation component 100 can enclose to form a heat dissipation duct 170. After the air enters the heat dissipation component 100 through the second air outlet 154, it can flow through the first fins 120 and the second fins 130 through the heat dissipation duct 170 and flow out of the heat dissipation component 100 through the first air outlet 152.

[0089] Specifically, at least two first fins 120 are spaced apart, and the first fin 120 and the second fin 130 are spaced apart, and the cover plate 140 covers the top of the first fin 120 and the second fin 130. Therefore, the interval between at least two first fins 120, the interval between the first fin 120 and the second fin 130, and the interval between the first fin 120 and the cover plate 140 together form a heat dissipation duct 170, so that when air flows through the heat dissipation duct 170, it can fully contact the cover plate 140, the first fin 120 and the second fin 130, thereby improving the heat exchange efficiency.

[0090] In the embodiment of the present application, since the cover plate 140 is connected to the second fin 130, the cover plate 140, the substrate 110, the second fin 130 and the first fin 120 can jointly serve as a heat dissipation structure to dissipate the heat transferred from the substrate 110. The cover plate 140, the second fin 130 and the first fin 120 are enclosed to form a heat dissipation duct 170. When the air flows through the heat dissipation duct 170, it can fully contact the cover plate 140, the second fin 130 and the first fin 120, thereby improving the heat exchange efficiency between the air and the cover plate 140, the second fin 130 and the first fin 120.

[0093] In this embodiment, the base plate 110 is provided with a first slot 162 for inserting the first fin 120, and a second slot 164 for inserting the second fin 130. Specifically, the first slots 162 are arranged at intervals, so that the first fins 120 are also arranged at intervals when they are arranged on the base plate 110 through the first slots 162, and the second slots 164 are arranged at intervals from the adjacent first slots 162, so that the second fins 130 inserted on the base plate 110 are arranged at intervals from the adjacent first fins 120.

[0094] Specifically, after the first fin 120 is plugged into the base plate 110 through the first slot 162 and the second fin 130 is plugged into the base plate 110 through the second slot 164, the first fin 120 and the second fin 130 are fixedly connected to the base plate 110 by welding, thereby improving the thermal conductivity of the base plate 110, the first fin 120 and the second fin 130.

[0095] In the embodiment of the present application, by setting the first slot 162 and the second slot 164 on the substrate 110, the first fin 120 and the second fin 130 can be pre-installed, and the installed first fin 120 and the second fin 130 are welded to the substrate 110 through the first slot 162 and the second slot 164, thereby improving the thermal conductivity between the first fin 120 and the second fin 130, thereby improving the heat dissipation efficiency of the heat dissipation assembly 100.

[0098] like Figure 1 and Figure 2 As shown, in some embodiments, an anodized film is disposed on at least two first fins 120 , the second fin 130 , the base plate 110 , and the cover plate 140 .

[0099] In the embodiment of the present application, by anodizing at least two first fins 120, the second fin 130, the substrate 110 and the cover plate, the surfaces of the first fin 120, the second fin 130, the substrate 110 and the cover plate are covered with an anodized film, thereby improving the thermal conductivity and corrosion resistance of the heat dissipation component 100.
