Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation structures, in particular to a heat dissipation component, an inverter and an electrical device. Background Art

[0002] In electrical devices, including power generation, transformation or distribution devices, inverters are commonly used. Since the working performance of the inverter is greatly affected by temperature, it is necessary to dissipate heat from the inverter to lower the temperature.

[0003] Generally, the inverter is cooled by an air-cooled radiator. A fan is used to blow air towards the radiator to take away the heat of the radiator, thereby ensuring the heat dissipation effect of the radiator on the inverter.

[0004] In the related art, a technical solution of directly blowing air towards the radiator by a fan is adopted. Such a heat dissipation structure will cause a relatively large temperature difference in each part of the radiator. When the local temperature is too high, it is necessary to continuously increase the air volume, or increase the number of fans, or increase the density of the teeth pitch to obtain a lower temperature, resulting in a large air volume loss and a low utilization efficiency of the radiator. Summary of the Utility Model

[0005] In view of this, the utility model provides a heat dissipation component, an inverter and an electrical device to solve the problem of low utilization efficiency of the radiator.

The radiator includes at least two air ducts that are cross-arranged and communicate with each other. The air inlet of the air duct faces the first direction; the fan is arranged on one side of the air inlet of the radiator, and the air outlet of the fan faces the opposite direction of the first direction.

[0007] Beneficial Effects: For the heat dissipation component provided by the utility model, since the radiator includes at least two air ducts that are cross-arranged and communicate with each other, and the fan blows air towards the air inlet direction of the radiator, the cold air can enter each air duct and reach each part smoothly, which can reduce the temperature difference in each part of the radiator and improve the heat dissipation effect. At the same time, the rotation speed of the fan can be adjusted according to the loss, which enhances the flexibility of the loss layout and the flexibility of local heat dissipation, and improves the utilization efficiency of the radiator. Compared with the radiator arranged as a whole in the related art, it can save the materials of the radiator.

[0008] In an alternative embodiment, the radiator includes a first heat sink and a second heat sink. The first heat sink includes a first bottom plate and a first fin group provided on the first bottom plate. The gaps within the first fin group form a first air duct; the first heat sink is provided with a first insertion notch that communicates with the first air duct; the second heat sink includes a second bottom plate and a second fin group provided on the second bottom plate. The gaps within the second fin group form a second air duct; the second heat sink is provided with a second insertion notch adapted to the first insertion notch, and the second insertion notch communicates with the second air duct; the first heat sink and the second heat sink are arranged crosswise, and the first insertion notch and the second insertion notch are correspondingly inserted along a first direction to communicate the first air duct and the second air duct.

[0009] In an alternative embodiment, the first insertion notch is located at the upper part of the first heat sink. Along the opposite direction of the first direction, the first insertion notch extends from the first fin group towards the first bottom plate but does not penetrate the first bottom plate; the second insertion notch is located at the lower part of the second heat sink. Along the first direction, the second insertion notch extends from the second bottom plate towards the second fin group but does not penetrate the second fin group.

[0010] In an alternative embodiment, the depth of the first insertion notch of the first heat sink is equal to the depth of the second insertion notch of the second heat sink, and on the air inlet side, the first heat sink and the second heat sink are flush.

[0011] In an alternative embodiment, the first heat sink is provided with a plurality of first insertion notches, and the second heat sink is provided with a plurality of them. Each second heat sink is arranged crosswise with the first heat sink, and the second insertion notches of each second heat sink are correspondingly inserted into the first insertion notches of the first heat sink one by one.

[0012] In an alternative embodiment, the plurality of second heat sinks are arranged in parallel.

[0013] In an alternative embodiment, the two air ducts are arranged perpendicularly.

[0014] In an alternative embodiment, the position of the fan is correspondingly set with respect to the intersection area of the two air ducts; or, a plurality of fans are provided, and in the intersection area of the two air ducts, adjacent fans are arranged in a staggered manner.

[0015] In a second aspect, the present utility model further provides an inverter, including the heat dissipation component in any one of the above technical solutions.

[0016] Beneficial effects: Since the inverter includes a heat dissipation component and has the same effects as the heat dissipation component, they will not be elaborated here.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0031] It should be noted that the "multiple" mentioned in this embodiment includes two.

[0032] The following Figures 1 to 8 , describes the embodiments of the present utility model.

[0033] According to an embodiment of the present utility model, in a first aspect, a heat dissipation assembly is provided, which includes a radiator 1 and a fan 2. The radiator 1 includes at least two air ducts that are cross - arranged and communicate with each other, and the air inlet of the air duct faces a first direction; the fan 2 is arranged on one side of the air inlet of the radiator 1, and the air outlet of the fan 2 faces the opposite direction of the first direction.

[0034] For the heat dissipation assembly provided by the embodiment of the present utility model, since the radiator 1 includes at least two air ducts that are cross - arranged and communicate with each other, and the fan 2 blows air towards the air inlet direction of the radiator 1, cold air can enter each air duct and smoothly reach each part of the radiator 1, which can reduce the temperature difference of each part of the radiator 1 and improve the heat dissipation effect. At the same time, the rotational speed of the fan 2 can be adjusted according to the loss, which enhances the flexibility of the loss layout and the flexibility of local heat dissipation, and improves the utilization efficiency of the radiator 1.

[0035] In addition, corresponding to the structure of the heat dissipation assembly provided in this embodiment, the air inlet area of a single fan 2 increases by nearly one - fold, which can greatly reduce the number of fans 2 and lower the cost.

[0036] In some embodiments, the radiator 1 includes a first heat dissipation member 11 and a second heat dissipation member 12. The first heat dissipation member 11 includes a first bottom plate 111 and a first fin group 112 arranged on the first bottom plate 111. The gap in the first fin group 112 forms a first air duct 114; the first heat dissipation member 11 is provided with a first insertion notch 113, and the first insertion notch 113 communicates with the first air duct 114; the second heat dissipation member 12 includes a second bottom plate 121 and a second fin group 122 arranged on the second bottom plate 121. The gap in the second fin group 122 forms a second air duct 124; the second heat dissipation member 12 is provided with a second insertion notch 123 adapted to the first insertion notch 113, and the second insertion notch 123 communicates with the second air duct 124; the first heat dissipation member 11 and the second heat dissipation member 12 are cross - arranged, and the first insertion notch 113 and the second insertion notch 123 are correspondingly inserted along the first direction to connect the first air duct 114 and the second air duct 124.

[0037] Specifically, the first fin group 112 includes a plurality of fins arranged in parallel, and the gaps between adjacent fins form the first air duct 114; similarly, the second fin group 122 includes a plurality of fins arranged in parallel, and the gaps between adjacent fins form the second air duct 124.

[0038] As Figure 1 shown in the embodiment, the direction indicated by F is the first direction. The air inlet of the radiator 1 faces upward, the fan 2 is arranged above the radiator 1, and the air outlet of the fan 2 faces downward, directly facing the air inlet of the radiator 1. When the fan 2 blows air downward, as Figure 6 indicated by the arrow in, under the guiding action of the second fin group 122 of the second heat dissipation member 12, part of the cold air flows along the length extension direction of the second fin group 122, and the other part enters the first fin group 112 of the first heat dissipation member 11 downward. Under the guiding action of the first fin group 112, it flows along the length extension direction of the first fin group 112. Thus, the cold air can reach all parts of the radiator 1.

[0039] By providing the first insertion notch 113 on the first heat dissipation member 11 and the second insertion notch 123 on the second heat dissipation member 12, the first heat dissipation member 11 and the second heat dissipation member 12 can be inserted and engaged through the first insertion notch 113 and the second insertion notch 123, realizing the cross arrangement of the first heat dissipation member 11 and the second heat dissipation member 12, and the first air duct 114 of the first heat dissipation member 11 communicates with the second air duct 124 of the second heat dissipation member 12. Compared with the radiator 1 integrally arranged in the related art, not only the heat dissipation effect is improved, but also the material of the radiator 1 can be saved.

[0040] The shapes of the first insertion notch 113 and the second insertion notch 123 are adapted to ensure that they will not interfere with each other when inserted.

[0041] In some embodiments, the first insertion notch 113 is located at the upper part of the first heat dissipation member 11. Along the opposite direction of the first direction, the first insertion notch 113 extends from the first fin group 112 to the first bottom plate 111 but does not penetrate the first bottom plate 111; the second insertion notch 123 is located at the lower part of the second heat dissipation member 12. Along the first direction, that is, the depth direction of the second insertion notch 123, the second insertion notch 123 extends from the second bottom plate 121 to the second fin group 122 but does not penetrate the second fin group 122.

[0042] With the first heat dissipation member 11 and the second heat dissipation member 12 arranged in this way, when they are placed crosswise with each other, the first insertion notch 113 and the second insertion notch 123 can be exactly engaged.

[0043] Since the first insertion notch 113 extends from the first fin group 112 to the first bottom plate 111 but does not penetrate the first bottom plate 111, the structures on both sides of the first insertion notch 113 can remain integrated, and the first heat sink 11 is an integral structure, which is convenient for assembly.

[0044] Similarly, since the second insertion notch 123 extends from the second bottom plate 121 to the second fin group 122 but does not penetrate the second fin group 122, the structures on both sides of the second insertion notch 123 can be ensured to remain integrated, and the second heat sink 12 is an integral structure, which is convenient for assembly.

[0045] In some embodiments, the depth of the first insertion notch 113 of the first heat sink 11 is equal to the depth of the second insertion notch 123 of the second heat sink 12. On the air inlet side, the first heat sink 11 and the second heat sink 12 are flush.

[0046] With such a setting, the loss of the fan 2 can be reduced and the heat dissipation effect can be improved.

[0047] The first insertion notch 113 can have different depths. In the embodiments shown in Figure 3 and Figure 4 , in the opposite direction of the first direction, the first insertion notch 113 does not penetrate the first fin group 112. In the embodiments shown in Figure 5 and Figure 6 , the first insertion notch 113 penetrates the first fin group 112 in the opposite direction of the first direction. After the second insertion notch 123 is inserted into the first insertion notch 113, there is a gap between the second insertion notch 123 and the first insertion notch 113 along the first direction, so that the air of the fan 2 can be blown from the second insertion notch 123 into the first insertion notch 113. Thus, the air blown by the fan 2 is blown from the second air duct 124 into the first air duct 114, achieving the effect of improving heat dissipation.

[0048] Of course, in some other embodiments, the depth of the first insertion notch 113 of the first heat sink 11 and the depth of the second insertion notch 123 of the second heat sink 12 are not equal, as long as it is ensured that the insertion of the first heat sink 11 and the second heat sink 12 does not interfere.

[0049] The overall heights of the first heat sink 11 and the second heat sink 12 can be equal or unequal, depending on the actual heat dissipation requirements.

[0050] In some embodiments, the heat sink 1 adopts the processing technology of shovel teeth.

[0051] In some embodiments, such as Figure 8As shown, the first heat sink 11 is provided with a plurality of first plug-in notches 113, and a plurality of second heat sinks 12 are provided, each second heat sink 12 is cross-arranged with the first heat sink 11, and the second plug-in notches 123 of each second heat sink 12 are plugged into the first plug-in notches 113 of the first heat sink 11 one by one.

[0052] According to the scale of the radiator 1, different numbers of second heat sinks 12 can be provided, so that the heat dissipation effect of the heat dissipation assembly as a whole can be improved, thereby improving the heat dissipation effect on heat-generating devices, such as inverters.

[0053] In some embodiments, the position of the fan 2 is set to correspond to the intersection area of ​​the two air ducts; or, a plurality of fans 2 are provided, and adjacent fans 2 are staggered in the intersection area of ​​the two air ducts.

[0054] Setting the position of the fan 2 to correspond to the intersection area of ​​the two air ducts can ensure that the air volume blown by the fan 2 to each area of ​​the radiator 1 is as balanced as possible, thereby reducing the situation of local overheating of the radiator 1.

[0055] like Figure 1 As shown, when two fans 2 are provided, the fans 2 are staggered in the intersection area of ​​the two air ducts to avoid energy loss caused by collision of the airflows of the two fans 2. Figure 7 As shown, when three or more fans 2 are provided, the fans 2 are arranged alternately in sequence, so that each part of the radiator 1 can be guaranteed to have sufficient air volume.

[0056] for Figure 8 In the embodiment shown, at least one fan 2 is disposed at the intersection of the first heat sink 11 and each second heat sink 12. The number of fans 2 is determined according to actual heat dissipation requirements.

[0057] For multiple fans 2 , the wind speed of the corresponding fans 2 can be specifically adjusted according to the actual heat dissipation conditions of different areas, while the other fans 2 remain unchanged, thereby improving the utilization efficiency of the radiator 1 .

[0058] In some embodiments, a plurality of second heat dissipation members 12 are arranged in parallel.

[0059] Specifically, the second fin groups 122 of the plurality of second heat sinks 12 are arranged in parallel, so that the overall layout of the heat sink 1 can be made more compact and reasonable.

[0060] In some embodiments, the two air ducts are arranged vertically.

[0061] Specifically, in Figure 2In the illustrated embodiment, the first heat sink 11 and the second heat sink 12 are arranged vertically, that is, the first fin group 112 and the second fin group 122 are arranged vertically. This arrangement facilitates the machining of the first insertion notch 113 and the second insertion notch 123.

[0062] According to an embodiment of the present invention, in a second aspect, an inverter is further provided, which includes the heat dissipation assembly in any one of the above embodiments.

[0063] Compared with traditional heat dissipation, when the inverter adopts the heat dissipation assembly in the above embodiment, the number of air ducts blown by the fan 2 directly against the radiator 1 increases by nearly one time, and the number of fans 2 can be correspondingly reduced. The length of the air duct is also shortened, weakening the self-heating effect of the air, which is more conducive to heat dissipation. The fans 2 are arranged staggeredly to ensure sufficient air volume for each part of the radiator 1. In addition, since the inverter includes the heat dissipation assembly and has the same effect as the heat dissipation assembly, it will not be elaborated here.

[0064] According to an embodiment of the present invention, in a third aspect, an electrical device is further provided, which includes the inverter in the above embodiment.

[0065] Since the electrical device includes the inverter and has the same effect as the inverter, it will not be elaborated here.

[0066] Specifically, the electrical device includes a power transformation device, a power distribution device or a power generation device.

[0067] Although the embodiments of the present invention are described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
