[0030] First embodiment

[0031] Please refer to Figure 1 and Figure 2 The present embodiment provides a radiator fan quick-release structure 100, which includes a housing 10, a radiator 20 and a fan assembly 30. The radiator 20 is fixedly mounted on one side of the housing 10. The fan assembly 30 is slidably connected to the housing 10 along a direction perpendicular to the blowing direction of the fan assembly 30. The fan assembly 30 has at least one position opposite to the radiator 20, so that the blowing direction of the fan assembly 30 corresponds to the radiator 20. The fan assembly 30 is detachably connected to the radiator 20.

[0032] Specifically, Figure 1 is a schematic diagram of a first state of the radiator fan quick-release structure 100, Figure 21 is a schematic diagram of the second state of the radiator fan quick-release structure 100. It can be understood that the first state is the relative position of the fan assembly 30 and the radiator 20. At this time, the fan assembly 30 is installed in place and can be in a working state or a standby state. The second state is the state where the fan assembly 30 is completely removed from the radiator 20 and the housing 10. At this time, the fan assembly 30 can be cleaned of dust or replaced.

[0033] It is understandable that the sliding direction of the fan assembly 30 relative to the housing 10 is perpendicular to the blowing direction of the fan assembly 30 , and the sliding direction of the fan assembly 30 relative to the housing 10 is located within the matching plane between the housing 10 and the fan assembly 30 .

[0034] Please refer to Figure 2 and Figure 3 Specifically, the fan assembly 30 includes a fan 32 and a fixing plate 31. The fixing plate 31 is provided with a mounting hole 311. The fan 32 is connected to the fixing plate 31 through the mounting hole 311. The fan 32 is provided with a slider 33. The housing 10 is provided with a guide rail 11. The slider 33 is slidably matched with the guide rail 11. The fixing plate 31 is detachably connected to the radiator 20.

[0035] In this embodiment, the fixing plate 31 is made of a sheet metal part by bending, and includes a fan mounting plate 314 and a connecting plate 315 vertically connected to the fan mounting plate 314. The bending length of the connecting plate 315 is greater than or equal to the thickness of the fan 32. The fan mounting plate 314 is used to mount the fan 32, and the connecting plate 315 is used to be detachably connected to the radiator 20. It can be understood that the fan mounting plate 314 and the connecting plate 315 surround and form a space for accommodating the fan 32.

[0036] Please refer to Figure 2 and Figure 4 Specifically, in this embodiment, the guide rail 11 is disposed on one side of the housing 10, and the shape of the guide rail 11 is a strip. The slider 33 is disposed on the side of the fan 32 close to the housing 10, and a groove is disposed on the slider 33. During installation, the groove of the slider 33 is aligned with the guide rail 11, and then the guide rail 11 is inserted into the groove, so that the fan 32 and the housing 10 can slide together, and the fan 32 is also limited so that it can only slide on the guide rail 11.

[0037] In order to facilitate the power supply to the fan 32, the guide rail 11 includes a positive rail 111 and a negative rail 112. The slider 33 includes a first slider 321 and a second slider 322. The first slider 321 contacts and slides with the positive rail 111. The second slider 322 contacts and slides with the negative rail 112. It can be understood that in this embodiment, the guide rail 11 and the slider 33 are both metal structures. When the fan 32 slides with the housing 10, the first slider 321 contacts the positive rail 111, and the second slider 322 also contacts the negative rail 112. The power supply inside the housing 10 is used to supply power, so that the fan 32 can be powered through the positive rail 111 and the negative rail 112.

[0038] Furthermore, an insulating member 12 is provided at the positive rail 111 and the negative rail 112. The insulating member 12 is fixed to the housing 10. In this embodiment, the insulating member 12 is an insulating insert, which is embedded in the housing 10, and a bar hole is opened on the insulating member 12. The positive rail 111 and the negative rail 112 can pass through the bar hole to expose the insulating member 12, so that the slider 33 on the fan 32 can avoid contact with external materials when cooperating with the rail 11, prevent short circuit, and improve the safety of the fan 32.

[0039] Please refer to Figure 3 Optionally, in order to improve the efficiency of heat dissipation, the number of fans 32 is at least two. The fans 32 are arranged on the guide rails 11 at intervals, and the fans 32 are slidably connected to the guide rails 11 respectively. In this embodiment, the number of fans 32 is two. In other embodiments, the number of fans 32 can be three, four, etc., which is not limited by the present invention.

[0040] It is understandable that the spacing between the fans 32 can be adjusted by sliding the fans 32. In this embodiment, the mounting holes 311 on the fixing plate 31 are fixed holes. When the spacing between the fans 32 is changed, it is necessary to change the position of the mounting holes 311 on the fixing plate 31, that is, the fixing plate 31 needs to be replaced.

[0041] Further, in other embodiments, the mounting hole 311 on the fixing plate 31 may be a strip hole, and the length direction of the strip hole is consistent with the sliding direction of the fan 32. The fan 32 is connected to the fixing plate 31 by screws. When adjusting the position of the fan 32, it is necessary to loosen the screws first, and then slide the fan 32, and the screws can slide in the strip holes. When the fan 32 is adjusted in place, the screws are tightened to fix the fan 32.

[0042] In order to improve the heat dissipation performance of the fan 32, a heat dissipation hole 312 is provided on the fixing plate 31. The position of the heat dissipation hole 312 corresponds to the fan 32. A heat dissipation plate 313 is fixed at the heat dissipation hole 312. The heat dissipation plate 313 is hollow, and the addition of the heat dissipation plate 313 can prevent dust from entering the fan 32, while ensuring the heat dissipation performance of the fan 32. Correspondingly, in other embodiments, in order to facilitate the adjustment of the position of the fan 32, the heat dissipation hole 312 can also be provided as a strip hole.

[0043] Please continue to refer to Figure 2 The radiator fan quick-release structure 100 further includes a fixed strap 22. The fixed strap 22 is detachably connected to the radiator 20. The fixed plate 31 is detachably connected to the fixed strap 22. It can be understood that the fixed strap 22 is disposed between the radiator 20 and the fan assembly 30, which increases the space between the fan 32 and the radiator 20 and enhances the effect of convection heat reduction.

[0044] In order to facilitate the fixing of the housing 10, a mounting plate 21 is also fixed on the radiator 20. The mounting plate 21 can enable the housing 10 and the radiator 20 to be fixed in an outdoor environment, thereby improving the stability of the structure.

[0045] Second embodiment

[0046] This embodiment provides a photovoltaic inverter 1000, which includes the radiator fan quick-release structure 100 provided in the first embodiment.

[0047] The beneficial effects of the radiator fan quick-release structure 100 of the photovoltaic inverter 1000 provided by the embodiment of the utility model are:

[0048] The radiator fan quick-release structure 100 includes a housing 10, a radiator 20 and a fan assembly 30. The radiator 20 is fixedly mounted on one side of the housing 10. The fan assembly 30 is slidably connected to the housing 10 along a blowing direction perpendicular to the fan assembly 30. The fan assembly 30 has at least one position relative to the radiator 20 so that the blowing direction of the fan assembly 30 corresponds to the radiator 20. The fan assembly 30 can be detachably connected to the radiator 20. By connecting the sliding connection of the fan assembly 30 with the housing 10 and the detachable connection with the radiator 20, when disassembling the fan assembly 30, it is only necessary to disconnect the connection between the radiator 20 and the fan assembly 30, and then slide the fan assembly 30 relative to the housing 10. The radiator fan quick-release structure 100 of the photovoltaic inverter 1000 provided by the utility model can realize the rapid disassembly of the fan 32, and the fan 32 can be replaced without disassembling the machine, and the number of fans 32 can be adjusted according to the use scenario and needs, and the fan 32 can be added or removed from the fan assembly 30, taking into account the heat dissipation effect and energy consumption.
