[0023] The cooling ring pipe 51 is fixedly connected to the outer tower shell 1 through a bracket, the water inlet end of the cooling ring pipe 51 penetrates the fixing ring 52 and the side wall of the outer tower shell 1, and the water outlet end of the cooling ring pipe 51 penetrates the bottom wall of the outer tower shell 1. The refrigerant enters the cooling ring pipe 51 from the water inlet end to cool the material at the lower part of the absorption tower, and the heated refrigerant flows out from the water outlet end at the bottom of the outer tower shell 1.

[0024] The conical diffusion head 55 is connected to the top of the transmission shaft 53 by screws, and the conical diffusion head 55 is connected to the limit ring 54 by a rotating shaft. When the transmission shaft 53 rotates, the conical diffusion head 55 is driven to rotate together, and the liquid falling from the top is diffused to the surrounding cooling ring tubes 51 by centrifugal force.

[0025] A spiral rod 56 is fixed on the conical surface above the conical diffusion head 55. The spiral rod 56 can cause the liquid droplets to be thrown out along the surface of the rod, thus playing a guiding role.

The motor drives the transmission shaft to rotate, driving the conical diffusion head to rotate together, and the liquid falling from the top is diffused to the surrounding cooling ring pipes through centrifugal force. At the same time, the U-shaped stirring blade rotates with the transmission shaft to stir the liquid so that the heat is evenly distributed and easy to dissipate. At the same time, the liquid can be diffused to the outer cooling ring pipe to accelerate the heat dissipation, and the liquid after the heat is dissipated is sent out from the discharge port.
