Description

Technical Field

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

[0002] In related technologies, inverters are typically equipped with a heat dissipation module to cool the electronic components inside the inverter. The heat dissipation module includes a housing and a fan. The fan is usually mounted on a fan bracket, which slides into the housing via guide rails. To facilitate installation, the fan bracket has bent edges at both ends. By sliding these bent edges within the guide rails, the fan bracket can slide relative to the housing. The bent edges on the fan bracket are bent towards the side where the fan is mounted.

[0003] The inventors of this application discovered that: because the bent edge on the fan bracket bends toward the side where the fan is installed, extra space needs to be reserved for the installation of the fan during the processing of the bent edge so that the fan can be properly installed between the bent edges of the fan bracket. As a result, the overall size of the fan bracket is easily too large, and the fan bracket easily occupies the internal space of the housing. Utility Model Content

[0011] In one optional embodiment, the housing is provided with a first heat dissipation hole and a second heat dissipation hole communicating with the receiving cavity, the first heat dissipation hole and the second heat dissipation hole being disposed opposite each other along the second direction; the heat dissipation device further includes a heat dissipation component, the heat dissipation component being disposed within the receiving cavity, the heat dissipation component being disposed opposite to the fan bracket along the second direction, the heat dissipation component being provided with a heat dissipation channel, the heat dissipation channel being disposed opposite to the first heat dissipation hole and the second heat dissipation hole along the second direction, the heat dissipation channel being located between the first heat dissipation hole and the second heat dissipation hole.

[0012] In one alternative embodiment, the heat sink includes a heat-conducting base and a plurality of heat sinks, the plurality of heat sinks being disposed on the heat-conducting base and spaced apart along the first direction, with adjacent heat sinks forming the heat dissipation channel.

[0014] According to another aspect of this application, an inverter is provided, including an inverter body and a heat dissipation device as described above, the heat dissipation device being detachably connected to the inverter body.

[0015] The beneficial effects of this application embodiment are as follows: Unlike the prior art, this application embodiment includes a housing, a fan bracket, and a fan. The housing has a receiving cavity and a mounting port communicating with the receiving cavity. The housing also has a first sliding groove extending in a first direction. The fan bracket is detachably connected to the housing and can slide from the mounting port into the receiving cavity along the first direction. The fan bracket includes a first surface and a second surface arranged opposite each other in a second direction. A first bent edge is provided at one end of the fan bracket in a third direction.

In the third direction, the projection of the fan does not coincide with the projection of the first bent edge. In this embodiment, the third direction is perpendicular to the first and second directions. Compared to related technologies, where the fan and the bent edge are located on the same side of the fan bracket, additional space needs to be reserved for the fan during the bending edge processing, which can easily lead to an overly large overall size of the fan bracket. However, in this embodiment, the fan and the first bent edge are located on different surfaces of the fan bracket. Therefore, no additional space needs to be provided for the fan during the first bending edge processing, thereby reducing the overall size of the fan bracket and reducing the internal space occupied by the fan bracket in the housing. In addition, the fact that the fan and the first bent edge are located on different surfaces of the fan bracket can reduce mutual interference between the first bent edge and the fan, making it easier to install the fan.

[0020] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0021] Please see Figure 1 The inverter 1000 includes an inverter body 10 and a heat dissipation device 20. The heat dissipation device 20 is detachably connected to the inverter body 10 and is used to dissipate heat from the electronic components inside the inverter body 10. The heat generated by the electronic components inside the inverter body 10 can be conducted to the heat dissipation device 20 through the casing or other heat-conducting components.

[0022] Regarding the inverter body 10 mentioned above, such as Figure 1 As shown, the main function of the inverter body 10 is to convert DC power into AC power and ensure that the output AC power is safely, stably and efficiently supplied to the load or the power grid.

[0023] For the aforementioned heat dissipation device 20, such as Figure 1 and Figure 2 As shown, the heat dissipation device 20 is detachably connected to the bottom of the inverter body 10. The heat dissipation device 20 can be used to dissipate heat from the electronic components inside the inverter body 10.

[0024] To better explain the structure of the heat dissipation device 20, the structure of the heat dissipation device 20 will be described in conjunction with the X, Y, and Z axes. The X, Y, and Z axes are perpendicular to each other. The first direction is along the X-axis, the second direction is along the Y-axis, and the third direction is along the Z-axis.

[0025] For details, please refer to Figure 2 The heat dissipation device 20 includes a housing 21, a fan bracket 22, and a fan 23. The housing 21 has a receiving cavity 21a and a mounting port 21b communicating with the receiving cavity 21a. The fan 23 is detachably mounted on the fan bracket 22, and the fan bracket 22 is detachably connected to the housing 21. The fan bracket 22 can slide from the mounting port 21b into the receiving cavity 21a along a first direction X. The receiving cavity 21a can accommodate components such as the fan bracket 22, the fan 23, and the heat sink 25. It is understood that the sliding insertion of the fan bracket 22 into the housing 21 facilitates its installation and removal, providing convenience for subsequent maintenance or replacement of the fan 23.

[0026] In some embodiments, the housing 21 includes a base plate 211 and a plurality of side plates connected in sequence. The plurality of side plates include a first side plate 212, a second side plate 213, a third side plate 214, and a fourth side plate 215. The base plate 211 is connected to one side of the plurality of side plates, and the other end of the plurality of side plates is detachably connected to the inverter body 10. The base plate 211, the first side plate 212, the second side plate 213, the third side plate 214, and the fourth side plate 215 enclose the aforementioned receiving cavity 21a. The first side plate 212 and the third side plate 214 are arranged opposite each other along the second direction Y, and the second side plate 213 and the fourth side plate 215 are arranged opposite each other along the first direction X. Optionally, the mounting port 21b is located on the fourth side plate 215.

[0027] In some embodiments, please refer to the following: Figure 3 The housing 21 is also provided with a first sliding groove 21c, which extends upward along a first direction X. The fan bracket 22 includes a first surface 22a and a second surface 22b disposed opposite to each other along a second direction Y. A first bent edge 221 is provided at one end of the fan bracket 22 along a third direction Z. The first bent edge 221 is slidably mounted in the first sliding groove 21c and can slide upward along the first sliding groove 21c in the first direction X, thereby enabling the fan bracket 22 to slide upward along the first direction X into the receiving cavity 21a. Optionally, the first sliding groove 21c is located at one end of the first side plate 212 along a third direction Z.

[0028] In some embodiments, the first bent edge 221 bends towards the second surface 22b, and the fan 23 is disposed on the first surface 22a. Along the third direction Z, the projection of the fan 23 does not coincide with the projection of the first bent edge 221. Compared to related technologies where the fan 23 and the bent edge are located on the same side of the fan bracket 22, additional installation space for the fan 23 needs to be reserved during the bending edge processing, which can easily lead to an overly large overall size of the fan bracket 22. In this application, the fan 23 and the first bent edge 221 are located on different surfaces of the fan bracket 22. Therefore, during the processing of the first bent edge 221, no additional installation space needs to be provided for the fan 23, thereby reducing the overall size of the fan bracket 22 and thus reducing the internal space occupied by the fan bracket 22 within the housing 21. Furthermore, the fact that the fan 23 and the first bent edge 221 are located on different surfaces of the fan bracket 22 reduces mutual interference between the first bent edge 221 and the fan 23, facilitating the installation of the fan 23.

[0029] In some embodiments, please refer to the following: Figures 4-6 The housing 21 is also provided with a second sliding groove 21d, which extends upward along the first direction X. The second sliding groove 21d and the first sliding groove 21c are arranged at intervals along the third direction Z. The fan bracket 22 is provided with a second bent edge 222 at the other end along the third direction Z. The second bent edge 222 and the first bent edge 221 are arranged opposite to each other along the third direction Z. The second bent edge 222 is slidably installed in the second sliding groove 21d. The second bent edge 222 can slide along the second sliding groove 21d in the first direction X. The second bent edge 222 bends towards the second surface 22b. The second bent edge 222 cooperates with the second sliding groove 21d to enable the fan bracket 22 to slide more stably into the receiving cavity 21a along the first direction X. Optionally, the first sliding groove 21c is located at the other end of the first side plate 212 along the third direction Z.

[0030] In some embodiments, the first bent edge 221 includes a first connecting portion 2211 and a first limiting portion 2212. One end of the first connecting portion 2211 is connected to the fan bracket 22, and the other end of the first connecting portion 2211 is connected to the first limiting portion 2212. The first limiting portion 2212 is installed in the first sliding groove 21c. The first limiting portion 2212 and the first sliding groove 21c are installed and cooperated to restrict the first bent edge 221 from disengaging from the first sliding groove 21c, so as to ensure a stable connection between the first bent edge 221 and the housing 21. At the same time, the first limiting portion 2212 and the first sliding groove 21c are installed and cooperated to realize the sliding connection of the first bent edge 221 to the housing 21.

[0031] In some embodiments, the second bent edge 222 includes a second connecting portion 2221 and a second limiting portion 2222. One end of the second connecting portion 2221 is connected to the fan bracket 22, and the other end of the second connecting portion 2221 is connected to the second limiting portion 2222. The second limiting portion 2222 is installed in the second sliding groove 21d. The second limiting portion 2222 and the second sliding groove 21d cooperate to restrict the second bent edge 222 from disengaging from the second sliding groove 21d, so as to ensure a stable connection between the second bent edge 222 and the housing 21. At the same time, the second limiting portion 2222 and the second sliding groove 21d are installed and cooperated to realize the sliding connection of the second bent edge 222 to the housing 21.

[0032] In some embodiments, the heat dissipation device 20 further includes connecting screws 24, and the fan 23 is connected to the fan bracket 22 via the connecting screws 24. It is understood that the connection method between the fan 23 and the fan bracket 22 includes, but is not limited to, screwing, riveting, snap-fitting, welding, etc. Optionally, there may be multiple fans 23, which are arranged at intervals along the first direction X. The arrangement of multiple fans 23 can improve the heat dissipation efficiency of the heat dissipation device 20.

[0033] In some embodiments, the length of the fan 23 along the third direction Z is d, and the length of the fan bracket 22 along the third direction Z is D, and D≥d. This setting ensures that the fan 23 can be smoothly installed on the fan bracket 22.

[0034] In some embodiments, please refer to Figure 2The housing 21 is provided with a first heat dissipation hole 212a and a second heat dissipation hole 214a communicating with the receiving cavity 21a. The first heat dissipation hole 212a and the second heat dissipation hole 214a are arranged opposite each other along the second direction Y. The heat dissipation device 20 also includes a heat dissipation component 25, which is disposed in the receiving cavity 21a. The heat dissipation component 25 and the fan bracket 22 are arranged opposite each other along the second direction Y. The heat dissipation component 25 is provided with a heat dissipation channel 25a, which is arranged opposite to the first heat dissipation hole 212a and the second heat dissipation hole 214a along the second direction Y. Located between the first heat dissipation hole 212a and the second heat dissipation hole 214a, heat generated by electronic components within the inverter body 10 is transferred to the heat sink 25. The heat is distributed within the heat dissipation channel 25a. External air can flow in from the first heat dissipation hole 212a, pass through the heat dissipation channel 25a, and then flow out from the second heat dissipation hole 214a, thereby carrying the heat within the heat dissipation channel 25a to the outside and achieving heat dissipation for the inverter body 10. The fan 23 can increase the gas flow rate within the receiving cavity 21a, thereby improving the heat dissipation efficiency of the heat dissipation device 20. It is understood that one of the first heat dissipation hole 212a and the second heat dissipation hole 214a is an air inlet and the other is an air outlet. This application does not impose a limitation. In the above embodiment, the first heat dissipation hole 212a is an air inlet and the second heat dissipation hole 214a is an air outlet. In other embodiments, the first heat dissipation hole 212a can be an air outlet and the second heat dissipation hole 214a can be an air inlet.

[0035] In some embodiments, the heat sink 25 includes a heat-conducting base 251 and a plurality of heat sinks 252. The plurality of heat sinks 252 are disposed on the heat-conducting base 251 and are spaced apart along a first direction X. A heat dissipation channel 25a is formed between adjacent heat sinks 252. The heat-conducting base 251 is used to fit against the inverter body 10 so as to conduct heat from the inverter body 10 to the plurality of heat sinks 252 and conduct heat to the outside through gas flow in the heat dissipation channel 25a.

[0036] In some embodiments, please refer to the following: Figure 4 and Figure 5 The fan bracket 22 is also provided with a handle 223 on the side away from the housing 21. This design allows the user to hold the handle 223 for easy installation and removal of the fan bracket 22.

[0037] In this embodiment, a housing 21, a fan bracket 22, and a fan 23 are provided. The housing 21 has a receiving cavity 21a and a mounting port 21b communicating with the receiving cavity 21a. The housing 21 also has a first sliding groove 21c extending upward along a first direction X. The fan bracket 22 is detachably connected to the housing 21 and can slide from the mounting port 21b into the receiving cavity 21a along the first direction X. The fan bracket 22 includes a first surface 22a and a second surface 22b arranged opposite each other along a second direction Y. A first bent edge 221 is provided at one end of the fan bracket 22 along a third direction Z. The first bent edge 221 is slidably mounted in the first sliding groove 21c and can slide upward along the first direction X along the first sliding groove 21c, bending towards the second surface 22b. The fan 23 is detachably connected to the fan bracket 22 and is disposed on the first surface 22a, extending upward along the third direction Z. The projection of 3 does not coincide with the projection of the first bent edge 221. The third direction Z is perpendicular to the first direction X and the second direction Y. Compared with the related technology, the fan 23 and the bent edge are located on the same side of the fan bracket 22. Therefore, during the processing of the bent edge, additional installation space for the fan 23 is required, which can easily lead to the overall size of the fan bracket 22 being too large. However, in this embodiment, the fan 23 and the first bent edge 221 are located on different surfaces of the fan bracket 22. Therefore, during the processing of the first bent edge 221, no additional installation space is required for the fan 23, thereby reducing the overall size of the fan bracket 22 and reducing the space occupied by the fan bracket 22 in the internal space of the housing 21. In addition, the fact that the fan 23 and the first bent edge 221 are located on different surfaces of the fan bracket 22 can reduce the mutual interference between the first bent edge 221 and the fan 23, so as to facilitate the installation of the fan 23.

[0038] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
