The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0019] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0020] The utility model embodiment provides a servo drive heat dissipation structure, such as Figure 1-4 As shown, it comprises: a box body 1, the interior of the box body 1 is divided into a water storage chamber 3 and a heat dissipation chamber 4 by a partition 2; the interior of the heat dissipation chamber 4 is fixedly connected to a servo driver body 5, the interior of the water storage chamber 3 is fixedly connected to a submersible pump 6, the output end of the submersible pump 6 is fixedly connected to a cooling pipe 7, the end of the cooling pipe 7 away from the submersible pump 6 is fixedly connected to a heat dissipation box 8, the middle part of the cooling pipe 7 is S-shaped and fixed to the surface of the servo driver body 5; the interior of the heat dissipation box 8 is provided with a cooling mechanism 9 for dissipating the heat of the water that absorbs the heat.

[0021] It should be noted that the submersible pump 6 transports the water inside the water storage chamber 3 to the inside of the heat sink 8 through the cooling pipe 7. The water absorbs the heat generated by the servo driver body 5 while flowing inside the cooling pipe 8, and then dissipates the heat in the water through the cooling mechanism 9, thereby realizing the heat dissipation of the servo driver body 5 by combining water cooling and air cooling, improving the heat dissipation effect of the servo driver body 5, and solving the problem that the current servo driver generally adopts the method of increasing the air flow speed near the servo driver to dissipate heat for the servo driver, resulting in a slow heat dissipation effect and poor heat dissipation effect.

[0022] In a further preferred embodiment of the present invention, Figure 1 , 4As shown, the cooling mechanism 9 includes: a heat-conducting copper plate 10 is fixedly connected to the inside of the heat-dissipating box 8, and a plurality of fins 11 are evenly arranged on one side of the heat-conducting copper plate 10 close to the cooling pipe 7, and the two sides of the fins 11 are respectively fixedly connected to the heat-conducting copper plate 10 and the heat-dissipating box 8; a return water pipe 12 is fixedly connected to the top of the heat-dissipating box 8, and the end of the return water pipe 12 away from the heat-dissipating box 8 passes through the partition 2 and is fixedly connected to the partition 2.

[0023] In this embodiment, the water inside the cooling tube 7 enters between the heat-conducting copper plate 10 and the heat sink 8, and is then transported through the water troughs between the fins 11. While the water flows in the water troughs between the fins 11, the fins 11 and the heat-conducting copper plate 10 absorb the heat inside the water. The cooled water flows back to the water storage chamber 3 through the return pipe 12, thereby achieving the purpose of water circulation.

Three micro motors 14 are evenly and fixedly connected inside the mounting rod 13, and the output ends of the micro motors 14 are fixedly connected with heat dissipation blades 15.

[0025] In this embodiment, the servo driver body 5 starts the micro motor 14 at the same time as it starts, and the output end of the micro motor 14 drives the heat dissipation blades 15, and the heat dissipation blades 15 rotate to quickly cool the heat-conducting copper plate 10, thereby improving the heat dissipation efficiency of water when it flows inside the heat dissipation box 8.

[0026] In a further preferred embodiment of the present invention, Figure 1 As shown, a heat dissipation port 16 is provided in the box body 1 near the heat dissipation blades 15 , and a dustproof net 17 is provided inside the heat dissipation port 16 . The dustproof net 17 is fixedly connected to the box body 1 .

[0027] In this embodiment, the heat dissipation blades 15 can discharge hot air through the heat dissipation ports 16 while rotating, and the provision of the dustproof net 17 can effectively prevent dust from entering the interior of the housing 1 without affecting heat dissipation.

[0028] In a further preferred embodiment of the present invention, Figure 1 As shown, the outer surfaces of the cooling pipe 7 and the return pipe 12 near the heat sink 8 are both sleeved with sealing rings 18 , and the sealing rings 18 are fixedly connected to the heat sink 8 .

[0029] In this embodiment, the sealing performance of the connection between the cooling pipe 7 and the return water pipe 12 and the heat dissipation box 8 is improved, thereby avoiding water leakage.

[0030] In a further preferred embodiment of the present invention, Figure 3 As shown, a water inlet 19 is provided on one side of the box body 1 close to the water storage chamber 3 , a sealing cover 20 is threadedly connected to the outer surface of the water inlet 19 , and a sealing gasket 21 is fixedly connected to the inside of the sealing cover 20 .
