The ramp 810 has a first end 811 adjacent the first divider 300 and a second end 812 adjacent the second divider 400. The distance from the first end 811 to the bottom plate 120 is less than the distance from the second end 812 to the bottom plate 120. Moreover, the air deflector 800 is not disposed between the first slots 500, so that a channel can be naturally formed between the adjacent first slots 500 for the airflow to pass through.

Portions of the bottom plate 120 to these third servo units 930.

The cover 200 is disposed on the housing 100. The cover 200 is spaced apart from the servo units 900 to form a third heat dissipation channel 210. In the embodiment, the side plate 110 has a plurality of ventilation holes 115 adjacent to the cover 200 and is connected to one end of the third heat dissipation channel 210. The cover 20 has an inner surface 201 that faces the bottom plate 120. The inner surface 201 protrudes from a wind deflecting surface 250. The wind deflector 250 has a first side 251 adjacent to the side panel 110 and a second side 252 away from the side panel 110. The distance from the first side 251 to the bottom panel 120 is greater than the distance from the second side 252 to the bottom panel 120. It should be noted that in other embodiments, the number of the vent holes 115 may be one. In addition, in other embodiments, the servo module 10 may not The cover 200 is included, and the side plate 110 may not have the ventilation hole 115.

Next, the heat dissipation process of the servo module 10 will be described. When a heat-dissipating airflow is blown in from the air inlet 111, most of the heat-dissipating airflow directly flows to the first heat-dissipating flow path 950, thereby flowing through the servo unit 910 on the first slot 500 to lower the temperature thereof, and a small portion of the heat-dissipating airflow. It will flow to the second heat dissipation channel 960. That is to say, this small portion of the heat dissipation airflow flows through the gap between the adjacent first slots 500. Since the heat radiating airflow between the adjacent first slots 500 does not flow through the first servo unit 910, the temperature thereof is maintained at a low temperature. The low-temperature heat dissipation airflow passes through the first heat dissipation hole 301 and flows to the slope 810 of the guide air plate 800. By the distance from the first end 811 of the slope 810 to the bottom plate 120 being less than the distance from the second end 812 of the slope 810 to the bottom plate 120, the low temperature heat dissipation airflow can be directed to the third servo unit 930 on the third slot 700. During the process of flowing to the third servo unit 930 on the third slot 700, a portion of the low temperature heat dissipation airflow also flows into the second servo unit 920 on the second slot 600. In this way, the second servo unit 920 on the second slot 600 and the third servo unit 930 on the third slot 700 are all blown by the low-temperature heat dissipation airflow, thereby improving the overall heat dissipation effect of the servo module 10. The servo unit which is far away from the air inlet 111 can also obtain good heat dissipation, and solves the problem of uneven heat dissipation of the servo module in the prior art.

In addition, since the side plate 110 has a plurality of ventilation holes 115 adjacent to the cover 200, the external airflow can flow from the ventilation holes 115 into the third heat dissipation flow path 210. Then, the airflow flows into the second servo unit 920 on the second slot 600 and the third servo unit 930 on the third slot 700 via the guiding of the air guiding ramp 250, to Heat these servo units. Since the airflow flowing from the vent hole 115 into the third heat dissipation channel 210 is located above the servo units, the temperature is in the second servo unit 920 flowing into the second slot 600 and the third servo unit 930 on the third slot 700. The temperature is kept low before, so the heat dissipation effect of the servo module 10 as a whole is improved, and the effect of uniform heat dissipation can be achieved.

According to the servo module of the above embodiment, since the air deflector has a slope, and the distance from the first end of the slope to the bottom plate is smaller than the distance from the second end of the slope to the bottom plate, part of the low-temperature heat dissipation airflow is guided by the inclined surface of the wind deflector. The second servo unit on the second slot and the third servo unit on the third slot improve the heat dissipation effect of the entire servo module and solve the problem of uneven heat dissipation.

Moreover, the air deflector is not disposed between the first slots, so that a channel can be naturally formed between the adjacent first slots for the airflow to pass through.

In addition, since the side plate has a plurality of ventilation holes adjacent to the cover body, and the inner surface of the cover body protrudes from the air guiding slope, the external airflow can flow into the flow channel from the ventilation hole, and then flows into the second slot through the guiding of the wind guiding slope. The second servo unit and the third servo unit on the third slot are used to improve the heat dissipation effect of the entire servo module.

While the present invention has been described above in terms of the preferred embodiments thereof, it is not intended to limit the invention, and the invention may be modified and modified without departing from the spirit and scope of the invention. The patent protection scope of the invention is subject to the definition of the scope of the patent application attached to the specification.
