▎ 摘　　要

NOVELTY - The device has a servo motor main body (1) whose upper end is provided with a semiconductor refrigerating sheet (2), where a lower end of the semiconductor refrigerating sheet is formed as a heat absorbing end and an upper end refrigerating sheet formed as a radiating end. An upper end of a radiating cover (3) is provided with a heat dissipation pore (14). An inner wall of a liquid storage tank is connected with a waterproof ventilating film. The liquid storage tank is filled with carbon dioxide solution. An end of a piston is connected with a telescopic air bag and a first magnet. An inner wall of an air extracting cylinder is connected with a second magnet. Two silencing plates are formed with multiple silencing holes and made of calcium silicate and glass wool materials. An inner wall of a heat conducting port is fixedly connected with a dustproof net that is made of stainless steel materials. A heat conducting sleeve is filled with graphene powder. USE - Servo motor cooling device. ADVANTAGE - The device realizes working process of the servo motor main body, absorbs heat of the servo motor main body by the lower end of the semiconductor refrigerating sheet, radiates heat of the servo motor main body by the radiating end, conducts heat through the radiating holes and the graphene powder in the heat conducting sleeve, vibrates the servo motor body during use to overflow carbon dioxide gas in carbon dioxide aqueous solution, expands the telescopic air bag to push the piston to carry out phase separation movement for extracting hot air and discharging the hot air quickly and realizes movement of the piston to attract the first magnet and the second magnet so as to generate strong repulsion force, so that the piston is reversely pushed back by a spring, thus realizing continuous air exhaust process. The device passes noise generates by the servo motor main body through the silencing hole in the silencing plate to resonate and convert into sound energy and cooperates with water in the annular water bag to absorb the noise for reaching effect of reducing the noise.
