Description

Technical Field

[0001] This utility model relates to the field of gearbox technology, and in particular to a gearbox housing with high heat dissipation for use in photovoltaic devices. Background Technology

[0002] A gearbox is a device used to transmit and change power. The main function of a gearbox is to change the speed and torque of the input shaft through the meshing of gears and transmit it to the output shaft, thereby driving related mechanical equipment.

[0003] Generally, a gearbox includes a gearbox housing and gear assemblies mounted within it. Currently, to improve gearbox heat dissipation, ventilation holes are typically added to the gearbox housing, allowing heat to escape from the gearbox and thus enhance heat dissipation. However, this method is less suitable when gearboxes are used in photovoltaic (PV) devices. Since most PV devices are installed outdoors, ventilation holes would allow dust, debris, and rainwater to easily enter the gearbox, hindering the proper functioning of the gear assemblies and shortening the gearbox's lifespan. Utility Model Content

[0004] The purpose of this invention is to provide a gearbox housing with high heat dissipation for photovoltaic devices, aiming to solve the technical problem that existing gearbox housings are prone to the mixing of external substances, resulting in a short service life.

[0005] This application provides a gearbox housing with high heat dissipation for a photovoltaic device, which includes a housing body, a heat dissipation component and a seal. The housing body has a receiving cavity for mounting the gear assembly. The lower surface of the housing body has a mounting groove communicating with the receiving cavity. The heat dissipation component is connected to the mounting groove and the mounting groove is sealed. The seal is disposed in the mounting groove and is located above the heat dissipation component.

[0006] The beneficial effects of the high heat dissipation gearbox housing for photovoltaic devices provided by this utility model are as follows: In the prior art, the heat inside the gearbox flows to the outside through heat dissipation holes, thereby reducing the heat inside the gearbox housing. Unlike the prior art, the gearbox housing of this application reduces the heat inside the gearbox housing through heat transfer; that is, the heat inside the gearbox housing is first transferred to a heat dissipation component with a high thermal conductivity, and then transferred to the outside. Furthermore, a sealing element is provided between the heat dissipation component and the mounting groove, making it difficult for external substances such as dust, debris, and rainwater to enter the gearbox housing, thus ensuring the normal operation of the gear assembly inside the gearbox housing. The design of the heat dissipation component and the sealing element gives the gearbox housing of this application both high heat dissipation performance and high sealing performance, thereby extending the service life of gearboxes using this gearbox housing, and broadening its applicability to harsher environments.

[0007] Optionally, the mounting groove includes a first groove segment and a second groove segment located below the first groove segment, with the seal and heat dissipation assembly both disposed within the second groove segment, wherein, in the vertical direction, at least a portion of the projection of the second groove segment falls outside the projection of the first groove segment.

[0008] Optionally, the seal is made of thermally conductive silicone.

[0009] Optionally, a through groove is provided in the middle of the seal, the through groove passing through the upper and lower surfaces of the seal, wherein, in the vertical direction, the first groove segment is exposed in the through groove.

[0010] Optionally, the heat dissipation assembly includes a heat sink and at least one heat dissipation fin. The heat sink is connected to a mounting groove, a seal is located above the heat sink, and the heat dissipation fin is connected to the lower surface of the heat sink, extending along a first direction. When there are at least two heat dissipation fins, all heat dissipation fins are arranged at intervals along a second direction. The first direction, the second direction, and the vertical direction are perpendicular to each other.

[0011] Optionally, the heat sink and heat sink fins are separate structures.

[0012] Optionally, a positioning groove is provided on the lower surface of the heat sink, and the heat sink fins are connected in the positioning groove.

[0013] Optionally, the heat sink is welded into the positioning groove.

[0014] Alternatively, the positioning groove does not penetrate the upper surface of the heat sink.

[0015] Optionally, the gearbox housing with high heat dissipation for photovoltaic devices further includes fasteners. The heat sink has a first through hole that penetrates both the upper and lower surfaces of the heat sink, and the seal has a second through hole that penetrates both the upper and lower surfaces of the seal. The wall of the mounting groove has a threaded hole. The fastener passes through the first and second through holes in sequence and is threadedly connected to the threaded hole.

[0030] Please refer to Figure 1 and Figure 2 The gearbox 100 with high heat dissipation for photovoltaic devices in the present invention will now be described.

[0031] Please refer to Figure 1 and Figure 2 The gearbox 100 with high heat dissipation for photovoltaic devices provided in this application includes a gearbox body 10, a heat dissipation component 20, and a sealing component 30. The gearbox body 10 has a receiving cavity 11 for mounting the gear component. The lower surface of the gearbox body 10 is provided with a mounting groove 12 that communicates with the receiving cavity 11. The heat dissipation component 20 is connected to the mounting groove 12 and the mounting groove 12 is sealed. The sealing component 30 is disposed in the mounting groove 12 and is located above the heat dissipation component 20.

[0032] Specifically, the mounting groove 12 extends vertically. The heat dissipation component 20 encloses the mounting groove 12, meaning the heat dissipation component 20 covers the lower opening of the mounting groove 12. In this application, the gearbox body 100 is a plastic part, and the heat dissipation component 20 is a metal part. This arrangement reduces production costs and simplifies the manufacturing process of the gearbox body 100. It is easy to understand that the overall structure of the gearbox body 100 is complex. If metal is used to manufacture the gearbox body 100, the complexity of the manufacturing process would increase the manufacturing difficulty and lengthen the production cycle.

[0033] In existing technologies, heat inside the gearbox 100 is dissipated to the outside through heat dissipation holes, thereby reducing the internal heat of the gearbox 100. Unlike existing technologies, the gearbox 100 of this application reduces internal heat through heat transfer; that is, the heat inside the gearbox 100 is first transferred to the heat dissipation component 20, which has a high thermal conductivity, and then transferred to the outside. Furthermore, a sealing element 30 is provided between the heat dissipation component 20 and the mounting groove 12, preventing external substances such as dust, debris, and rainwater from entering the gearbox 100, thus ensuring the normal operation of the gear assembly inside the gearbox 100. The combination of the heat dissipation component 20 and the sealing element 30 gives the gearbox 100 both high heat dissipation and high sealing performance, thus extending the service life of gearboxes using this gearbox 100 and broadening its applicability to harsher environments.

[0034] In another embodiment of this application, please refer to Figure 1 and Figure 2 The mounting groove 12 includes a first groove segment 121 and a second groove segment 122 located below the first groove segment 121. The sealing element 30 and the heat dissipation assembly 20 are both disposed within the second groove segment 122. Specifically, in the vertical direction, at least a portion of the projection of the second groove segment 122 falls outside the projection of the first groove segment 121. The mounting groove 12 is a stepped structure overall. The arrangement of the first groove segment 121 and the second groove segment 122 greatly facilitates the installation of the heat dissipation assembly 20, which is beneficial for improving the production efficiency of the gearbox body 100.

[0035] In another embodiment of this application, the sealing element 30 is made of thermally conductive silicone. This configuration ensures the sealing performance of the gearbox 100 while further improving its heat dissipation performance.

[0036] In another embodiment of this application, please refer to Figure 2A through groove 31 is provided in the middle of the seal 30, and the through groove 31 penetrates the upper and lower surfaces of the seal 30. In the vertical direction, the first groove segment 121 is exposed in the through groove 31. Specifically, the through groove 31 extends in the vertical direction. The through groove 31 ensures the heat dissipation performance of the gearbox body 100.

[0037] In another embodiment of this application, please refer to Figure 1 and Figure 2 The heat dissipation assembly 20 includes a heat sink 21 and at least one heat dissipation fin 22. The heat sink 21 is connected to the mounting groove 12, and the sealing member 30 is located above the heat sink 21. The heat dissipation fin 22 is connected to the lower surface of the heat sink 21 and extends along a first direction. When the number of heat dissipation fins 22 is at least two, all heat dissipation fins 22 are arranged at intervals along a second direction. The first direction, the second direction, and the vertical direction are perpendicular to each other.

[0038] Specifically, in this application, the heat dissipation fins 22 are generally rectangular in shape. However, in other embodiments, the heat dissipation fins 22 may also be wavy or other shapes, which is not limited here. Four heat dissipation fins 22 are provided; however, in other embodiments, there may be two, three, or more heat dissipation fins 22, which is not limited here. The first direction is the left-right direction, and the second direction is the front-back direction. The arrangement of the heat dissipation fins 22 can increase the heat dissipation area of ​​the heat dissipation assembly 20, which is beneficial to improving the heat dissipation performance of the heat dissipation assembly 20.

[0039] In another embodiment of this application, the heat sink 21 and the heat sink fins 22 are separate structures.

[0040] Since the heat dissipation component 20 is a metal part, such as aluminum alloy, processing the heat dissipation component 21 and the heat dissipation fins 22 separately and assembling them together can reduce production difficulty and improve production efficiency. In addition, the split design can also save materials and reduce material waste.

[0041] In another embodiment of this application, please refer to Figure 2 A positioning groove 211 is provided on the lower surface of the heat sink 21, and the heat sink fins 22 are connected in the positioning groove 211. Specifically, the heat sink fins 22 protrude from the positioning groove 211, that is, the heat sink fins 22 protrude from the lower surface of the heat sink 21, so as to ensure the heat dissipation performance of the heat dissipation assembly 20. The positioning groove 211 is used to position the heat sink fins 22, which can effectively improve the assembly efficiency of the heat dissipation assembly 20.

[0042] In another embodiment of this application, the heat sink 21 is welded into the positioning groove 211. By welding, the heat sink fins 22 and the heat sink 21 are connected together, which can effectively improve the assembly efficiency while ensuring the connection strength between the two.

[0043] In another embodiment of this application, the positioning groove 211 does not penetrate the upper surface of the heat sink 21. This arrangement ensures the sealing performance of the gearbox body 100.

[0044] In another embodiment of this application, please refer to Figure 2 The gearbox housing 100 also includes fasteners (not shown in the figure). The heat sink 21 has a first through hole 212 that penetrates both the upper and lower surfaces of the heat sink 21. The sealing element 30 has a second through hole 32 that penetrates both the upper and lower surfaces of the sealing element 30. The wall of the mounting groove 12 has a threaded hole 1221. The fasteners pass through the first through hole 212 and the second through hole 32 in sequence and are threadedly connected to the threaded hole 1221.

[0045] Specifically, the first through hole 212, the second through hole 32, and the threaded hole 1221 all extend in the vertical direction. The threaded hole 1221 is located on the upper wall of the second groove segment 122 and extends in the vertical direction. Fasteners can be bolts or screws, as long as they can be threaded into the threaded hole 1221 and connect the housing body 10 and the heat sink 21 together; no limitation is made here. In this application, a threaded connection is used to achieve a detachable connection between the heat sink 21 and the housing body 10, thus enabling the replacement of the heat dissipation component 20 and greatly improving practicality and flexibility.

[0046] In another embodiment of this application, the threaded hole 1221 is a blind hole structure, that is, the threaded hole 1221 does not communicate with the receiving cavity 11. This configuration ensures the sealing performance of the gearbox body 100.

[0047] In another embodiment of this application, the diameter of the second through hole 32 is larger than the diameter of the first through hole 212. This arrangement facilitates the fasteners to pass through the seal 30 and can effectively improve the assembly efficiency of the gearbox body 100.

[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
