[0040] The heat dissipation housing includes two front and rear positioning side plates 1200, and a heat dissipation fin structure 1300 is wrapped between the two positioning side plates 1200. The heat dissipation fin structure 1300 can effectively reduce the internal temperature and realize internal and external heat exchange;

[0041] The driving gear assembly 11 drives the first rotating communication structure 8 and the second rotating communication structure 6 to rotate at a ratio of 2:1;

[0042] The number of the first heat exchange and delivery pipes 9 is less than the number of the second heat exchange and delivery pipes 7;

[0044] The cooling medium circulation channel 4 is connected, and the cooling medium circulation channel 4 can circulate the cooling medium to the first heat exchange chamber 2 and the second heat exchange chamber 3, and finally circulate to the external circulation pump to cool the cooling medium. The cooling medium with a lower temperature first passes through the first heat exchange chamber 2 at the bottom, and the cooling medium after heat exchange passes through the second heat exchange chamber 3 above for heat exchange, so that the mixture can be gradually cooled and heat exchanged when flowing from top to bottom.
