[0027] The cooling assembly comprises a water inlet pipe 208 fixedly communicated with the upper end of the tank body 2, a water outlet pipe 209 fixedly communicated with the lower end of the tank body 2, an air inlet pipe 203 fixedly communicated with the lower surface of the first sealing cover 201, an air outlet pipe 204 fixedly communicated with the upper end of the first sealing cover 201, a communication plate 205 fixedly communicated with both ends of the tank body 2, and a plurality of evenly distributed circular pipes 207 fixedly communicated in the two communication plates 205.
