the plurality of guide plates 19 are arranged, so that when the air flow passes through the guide plates 19, the air flow is continuously turned along the guide plates 19 which are arranged in a staggered way and finally reaches the middle part of the air inlet box 9, the contact area between the air flow and the guide plates 19 can be effectively increased, and the temperature transfer effect is improved;
in order to keep the surface of the condensation pipe 15 at room temperature all the time, the water flow in the circulation box 16 is continuously sucked by the water suction pump 20, and is discharged by the drainage pump 21 after the condensation pipe 15 is filled, the filter is used for isolating foreign matters in water from entering the condensation pipe 15 and preventing the condensation pipe 15 from being blocked, and the operation ensures that the surface of the condensation pipe 15 is always low in temperature and can be rapidly condensed to pass through high-temperature air flow.
The foregoing has shown and described the basic principles, principal features and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present invention, and various changes and modifications may be made without departing from the spirit and scope of the invention, which is defined in the appended claims. The scope of the invention is defined by the appended claims and equivalents thereof.
