[0048] Example 7

[0049] Based on Example 5, Figure 8-Figure 9 , an integrated electro-hydraulic servo mechanism, in order to improve the use effect of the oil storage cylinder 6 and cooperate with the overall improvement of the cooling effect in the installation shell 1, a spring 25 is fixed to the inner wall of the top end of the oil storage cylinder 6, and a piston 26 slidably connected to the inner wall of the oil storage cylinder 6 is fixed to the bottom end of the spring 25.

In actual use, during the process of controlling the flow of oil in the electro-hydraulic servo valve 5, the oil in the hydraulic cylinder 3 and the oil reservoir 6 will change dynamically in the opposite direction. When the oil in the oil reservoir 6 increases and squeezes the piston 26 upward, the volume of the dispersed air cavity 32 is increased through the limit tube 27 to squeeze the air cavity in the mounting shell 1. When the oil in the oil reservoir 6 decreases and the piston 26 is pushed downward by the spring 25, the volume of the dispersed air cavity 32 is reduced through the limit tube 27, thereby changing the air cavity in the mounting shell 1 through the movement of the oil to increase the flow rate of the airflow and the change of the airflow, thereby cooperating with the oil movement for heat exchange to further enhance the actual heat dissipation and cooling effect in the mounting shell 1, thereby further enhancing the effectiveness and use effect of the integrated electro-hydraulic servo mechanism for a long time.

When actually in use, the connecting portion 35 is recessed inwardly through the protruding setting of the extension portion 34 and the arc-shaped portion protruding outward at the end of the mounting portion 33, so that the extended heat sink 39 does not extend longer than the extension portion 34, thereby not affecting the normal installation and use of the mounting shell 1; and the change in the chamber width generated inside the shell by the extension portion 34 and the mounting portion 33, in conjunction with the heat sink 39 and the oil flow heat exchange, the gas flow heat exchange effect in the mounting shell 1 is further improved, thereby further enhancing the actual heat dissipation and cooling effect of long-term use, so as to enhance the effectiveness of the integrated electro-hydraulic servo mechanism for long-term use.

[0053] Further, see Fig.10 The dispersed air cavity 32 is provided with four groups of airbag mechanisms corresponding to the extension part 34. The airbag mechanism is provided with a plurality of airbags 2 36 distributed in the vertical direction. A ventilation pipe 37 is connected between two adjacent airbags 2 36. A connecting pipe 38 is connected between the tops of two adjacent airbag mechanisms. The air pipe 1 24 and the air pipe 2 29 are both arranged below the middle position of the airbag mechanism. The ventilation pipe 37 and the connecting pipe 38 are both made of heat-conducting metal materials. The bottom end of the airbag mechanism is detachably fixed to the inner wall of the mounting shell 1, so that the airbag 1 23 at the corresponding position of the electro-hydraulic servo valve 5 is The temperature changes and squeezes the airflow into the airbag 2 36 on the corresponding side, and the airflow corresponding to the position of the oil storage cylinder 6 flows into the airbag 2 36 on the other side, so that the airflow changes are dispersed in the vertical direction and gathered in the connecting pipe 38 at the top position, so as to improve the airflow movement change effect in the installation shell 1 by changing through the airbag 2 36 at each position, and improve the heat exchange and cooling effect of the top heat by increasing the airflow movement velocity at the top position by converging the airflow at the top, thereby improving the integration effect of the integrated electro-hydraulic servo mechanism and improving the overall long-term use effect.
