[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] As shown in the attached Figures 1-6A servo motor air-cooled and self-cooled integrated housing as shown. A distributed diversion heat dissipation mechanism is provided on the servo motor air-cooled and self-cooled integrated housing. The setting of the distributed diversion heat dissipation mechanism can achieve compression diversion through multiple guiding holes 5 and heat dissipation branch holes 6, and can achieve multi-point distributed diversion heat dissipation inside the housing 2, with a wider heat dissipation area and greatly improved heat dissipation effect. The specific structural setting of the distributed diversion heat dissipation mechanism is as follows.

[0023] In this embodiment, as shown in the appendix Figures 1-3 As shown, the distributed diversion heat dissipation mechanism includes multiple groups of distribution holes 3 opened on the inner wall of the housing 2.

The vertical cross-sectional shape of the heat dissipation branch holes 6 is set as a cross shape, and the inner walls of the heat dissipation branch holes 6 and the guiding holes 5 are both set as smooth surfaces.

[0024] When the servo motor air-cooled and self-cooled integrated housing of this technical solution is in use, the servo motor is installed at the inner position of the housing 2. Through the external wind force, the wind force can be compressed into the multiple distribution holes 3, and achieve transverse diversion along the multiple distribution holes 3, and then achieve compression diversion along the multiple diversion holes 4, and then achieve diversion along the multiple guiding holes 5. Through the multiple guiding holes 5 and the heat dissipation branch holes 6, compression diversion is achieved. The wind force can continuously pour in for diversion, and through the multiple guiding side holes 7, the multiple communication holes 8 and the multiple diversion branch holes 9, flat compression contact is achieved. The two groups of upper heat dissipation holes 10 achieve extrusion diversion, and the heat conduction through holes 11 achieve diversion heat dissipation. After contact, compression diversion heat dissipation is achieved. The housing 2 has its own air duct, and the housing 2 can be used for natural cooling or as an air-cooled housing.

The plurality of heat-conducting bars 16 and the support ring 1 are integrally formed by die-casting. The heat-conducting bars 16 and the arc-shaped bars 17 are both made of copper material.

[0026] When the air-cooled and self-cooled integrated housing of the motor in this technical solution is in use, the motor component is placed at the end of the reinforcing block 13 and is located in the space surrounded by the plurality of heat-conducting bars 16. Heat is conducted from the motor component to the plurality of heat-conducting bars 16 and then diverted to the plurality of arc-shaped bars 17, forming rapid heat conduction and outflow in each interval space. Moreover, the support ring 1 supports the outer ring 14 and the inner ring 15. The outer ring 14 and the inner ring 15 can provide a supporting force for the plurality of heat-conducting bars 16.
