[0060] Embodiment 1

[0061] As Figures 1 to 9 shown, this embodiment provides a heat dissipation mechanism, including a box body 1, a first limiting plate 2, a second limiting plate 3, a fan assembly 4, and a third limiting plate 5; the first limiting plate 2 is arranged at one end of the box body 1; the second limiting plate 3 is arranged at the other end of the box body 1; the fan assembly 4 is clamped between the first limiting plate 2 and the second limiting plate 3, and a wire storage cavity is formed by enclosing the fan assembly 4 and the second limiting plate 3, and a connection joint assembly 6 is adapted to be placed in the wire storage cavity; the third limiting plate 5 covers the first limiting plate 2 and the second limiting plate 3, and the third limiting plate 5 is adapted to cover the fan assembly 4.

[0062] In the embodiment of the present utility model, first, both ends of the fan assembly 4 are respectively installed on the first limiting plate 2 and the second limiting plate 3, and then the connection joint assembly 6 is connected outside the wire storage cavity. After the connection is completed, the connection joint assembly 6 is retracted into the wire storage cavity to complete the installation and wiring process of the fan assembly 4.

[0063] During the operation of the inverter, heat dissipation is required, so an external heat dissipation mechanism is provided on the inverter. However, the external heat dissipation mechanism is prone to failure, and thus the heat dissipation mechanism needs to be replaced. During the replacement process of the heat dissipation mechanism, it is necessary to disconnect the connecting wires while disassembling and assembling the heat dissipation mechanism, making the disassembly, assembly, and replacement of the heat dissipation mechanism rather cumbersome, thus affecting the use of the inverter. In the embodiment of the present utility model, by clamping the fan assembly 4 between the first limiting plate 2 and the second limiting plate 3, and then connecting the connection joint assembly 6 outside the wire storage cavity. After the connection is completed, the connection joint assembly 6 is hidden in the wire storage cavity. In this way, when replacing the fan assembly 4, through the clamping of the first limiting plate 2 and the second limiting plate 3, the replacement of the fan assembly 4 becomes more convenient. At the same time, when connecting the connection joint assembly 6, it is no longer necessary to manually support the fan assembly 4, thereby improving the replacement efficiency of the fan assembly 4.

[0064] Further, the first limiting plate 2 is provided with a limiting convex block 21, and the limiting convex block 21 is used for clamping with the fan assembly 4. That is to say, the limiting convex block 21 is clamped with the left end of the fan assembly 4; a buffer member 22 is further provided on the first limiting plate 2, and the buffer member 22 is arranged around the limiting convex block 21, and the buffer member 22 is adapted to buffer the clamping between the fan assembly 4 and the first limiting plate 2. In the embodiment of the present utility model, the buffer member 22 is arranged as buffer cotton, or can also be arranged as buffer rubber. The type of the buffer member 22 is not limited in this embodiment, and those skilled in the art can change the type of the buffer member 22 according to the actual situation as long as the same technical effect can be achieved.

[0065] Further, the second limiting plate 3 is provided with a clamping member 31, and the clamping member 31 is adapted to clamp with the fan assembly 4. That is to say, the clamping member 31 is clamped with the right end of the fan assembly 4. In the embodiment of the present utility model, by providing the limiting convex block 21 on the first limiting plate 2 and the clamping member 31 on the second limiting plate 3, the fan assembly 4 can be clamped more conveniently, and the structure is relatively simple, with no difficulty in processing, and has strong versatility, and can be applied to various application scenarios.

[0066] Further, as Figure 1As shown, the fan assembly 4 includes a fan bracket 41, a plurality of fans 42, a baffle 43, and a sliding plate 44. The fan bracket 41 is installed between the first limit plate 2 and the second limit plate 3. A plurality of fans 42 are respectively installed in the fan bracket 41. One end of the fan 42 close to the second limit plate 3 leads out a signal line terminal 421, and the signal line terminal 421 is communicatively connected to the connection joint assembly 6. The baffle 43 is arranged on the fan bracket 41, and the baffle 43 is adapted to block the connection joint assembly 6. The sliding plate 44 is slidably connected to the fan bracket 41 and is adapted to close the wire storage cavity. After the sliding plate 44 closes the wire storage cavity, the sliding plate 44 is connected to the fan bracket 41 by screws 45. In the embodiment of the present invention, four fans 42 are provided. Of course, it can also be set to a plurality of fans. The embodiment does not limit the number of the fans 42. Those skilled in the art can change the number of the fans 42 according to the actual situation as long as the same technical effects can be achieved. In addition, in this embodiment, the fan assembly 4 can also be set as a whole for overall disassembly and assembly, so as to make the replacement of the fan assembly 4 more convenient.

[0067] Further, a wire storage cavity is arranged at one end of the fan bracket 41 close to the second limit plate 3. The wire storage cavity is enclosed and formed by the fan bracket 41, the sliding plate 44, and the second limit plate 3. The connection joint assembly 6 is arranged in the wire storage cavity. In the embodiment of the present invention, by arranging the connection joint assembly 6 in the wire storage cavity and arranging the wire storage cavity at one end of the fan bracket 41 close to the second limit plate 3, the heat dissipation air duct of the fan assembly 4 is avoided, so that the connection joint assembly 6 avoids the heat dissipation air duct, reduces the wind resistance, and further improves the heat dissipation efficiency of the fan assembly 4.

[0068] As Figures 4 to 7 shown, when the connection joint assembly 6 needs to be wired after the fan assembly 4 is installed, first stretch the connection joint assembly 6 to the outside of the wire storage cavity, perform plug-in connection on the connection joint assembly 6. After the connection is completed, then retract the connection joint assembly 6 into the wire storage cavity, and then slide the sliding plate 44 upward to make the sliding plate 44 flush with the second limit plate 3, and then fixedly connect the sliding plate 44, the fan bracket 41, and the second limit plate 3 by the screws 45 to complete the closure of the wire storage cavity.

[0069] Further, a limiting groove 411 is provided at one end of the fan bracket 41 close to the first limiting plate 2. The limiting groove 411 is correspondingly clamped with the limiting bump 21. A limiting hole 412 is provided at the end of the fan bracket 41 away from the first limiting plate 2. The limiting hole 412 is correspondingly clamped with the clamping member 31. Through the clamping of the limiting groove 411 and the limiting bump 21, and the clamping of the limiting hole 412 and the clamping member 31, the left - right direction of the fan assembly 4 can be limited. In addition, it can also play a supporting role for the fan assembly 4.

[0070] As Figures 2 to 7 shown, when the fan assembly 4 needs to be installed, first insert the limiting groove 411 onto the limiting bump 21, so that the right end of the fan assembly 4 is clamped with the first limiting plate 2. Then, sleuth the limiting hole 412 onto the clamping member 31, so that the left end of the fan assembly 4 is clamped with the second limiting plate 3. Then, perform a plug - in connection on the connection joint assembly 6 outside the wire - hiding cavity. After the plug - in connection is completed, retract the connection joint assembly 6 into the wire - hiding cavity, and then close the wire - hiding cavity through the sliding plate 44. When the fan assembly 4 needs to be disassembled, just reverse the above process.

[0071] In the embodiment of the present utility model, as Figure 8 and Figure 9 shown, the fan assembly 4 can be rotated to the horizontal position at a small angle and then inserted between the first limiting plate 2 and the second limiting plate 3. Of course, the fan assembly 4 can also be directly inserted horizontally between the first limiting plate 2 and the second limiting plate 3.

[0072] Further, the connection joint assembly 6 includes a first joint 61 and a second joint 62. The first joint 61 is arranged in the wire - hiding cavity, and the first joint 61 is connected to the signal - wire terminal 421. The second joint 62 is arranged in the wire - hiding cavity, and one end of the second joint 62 is in plug - in connection with the first joint 61. In the embodiment of the present utility model, when the first joint 61 and the second joint 62 need to be in plug - in connection, the first joint 61 and the second joint 62 can be stretched to the outside of the wire - hiding cavity for plug - in connection. After the plug - in connection is completed, the first joint 61 and the second joint 62 are retracted into the wire - hiding cavity. This operation makes the connection between the first joint 61 and the second joint 62 more convenient.

[0073] Further, the heat dissipation mechanism further includes a waterproof connector 7. A wiring terminal 71 is provided in the waterproof connector 7. The wiring terminal 71 is led out from the control module in the box body 1. The wiring terminal 71 is connected to the other end of the second connector 62, connected to the signal line terminal 421 through the first connector 61, and the second connector 62 is connected to the wiring terminal 71. Then, by inserting the first connector 61 and the second connector 62 into each other, the control module of the inverter can be connected and conducted with the fan assembly 4. In addition, the waterproof connector 7 can prevent external water and impurities from entering the inverter. Through the wiring terminal 71, the inverter can be communicatively connected to the fan assembly 4, enabling the inverter to control the fan assembly 4.

[0074] Further, a first reinforcing rib 51 is provided on the third limiting plate 5, and a second reinforcing rib 8 is further provided on the box body 1. The second reinforcing rib 8 is arranged corresponding to the first reinforcing rib 51. Both the first reinforcing rib 51 and the second reinforcing rib 8 extend towards the fan direction. The second reinforcing rib 8 and the first reinforcing rib 51 are adapted to limit the fan assembly 4. During the installation process of the fan assembly 4, when the limiting bump 21 is docked with the limiting groove 411, the first reinforcing rib 51 and the second reinforcing rib 8 respectively abut against the fan assembly 4, thereby limiting the upward movement direction of the fan assembly 4 and preventing the fan assembly 4 from moving excessively into the box body 1, resulting in the inability to dock the limiting bump 21 with the limiting groove 411. In addition, the third limiting plate 5 and the end face of the box body 1 can also limit the fan assembly 4 in the front-back direction.

[0075] Further, a heat sink 9 is provided on the box body 1. The heat sink 9 is located between the first limiting plate 2 and the second limiting plate 3 and is also arranged above the fan assembly 4. The air flow generated by the fan assembly 4 passes through the heat sink 9 and blows out from bottom to top, thereby dissipating heat from the inverter.

[0076] The specific working process of the heat dissipation mechanism provided by the present utility model is as follows:

[0077] First, dock the limit groove 411 with the limit bump 21 so that the fan assembly 4 is snapped onto the first limit plate 2. Then, slip the limit hole 412 over the snap member 31 to connect the fan assembly 4 to the second limit plate 3. Next, connect the first connector 61 to the signal line terminal 421, and then connect the second connector 62 to the adapter wire terminal 71. Then, plug the first connector 61 and the second connector 62 into each other. After that, retract the connected first connector 61 and second connector 62 into the wire storage cavity. Then, slide the sliding plate 44 upward until the sliding plate 44 is flush with the second limit plate 3. Finally, fixedly connect the sliding plate 44, the fan bracket 41, and the second limit plate 3 with the screw 45 to close the wire storage cavity, thereby completing the replacement and wiring process of the fan assembly 4.

[0080] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. The obvious changes or variations derived therefrom still fall within the protection scope of the present invention.
