[0034] The working principle and use process of the utility model are as follows: when in use, the elliptical tube is used as the main place for heat exchange and is located inside the support plate, and the support plate is fixedly connected to the inside of the shell. The outside of the elliptical tube is equipped with a first arc plate and a second arc plate, which are connected to the movable plate through a sleeve and rotate under the drive of the first screw. This design enables the cleaning brush to be close to the outside of the elliptical tube and effectively clean the dust on its surface. The first screw is fixedly connected to the motor, and the motor provides power to rotate the first screw, thereby pushing the movable plate to move, so that the cleaning brush cleans the elliptical tube. At the same time, in order to ensure the cleaning effect of the cleaning brush, the second screw is set on the top of the movable block, and the second screw can be conveniently adjusted by a hand-tightening piece. The position of the cleaning brush can be changed to change the pressure and cleaning effect of the cleaning brush. Outside the cleaning system, the spray mechanism is responsible for spraying liquid cleaning on the elliptical tube. The diverter box, the atomizing nozzle and the water pump constitute a closed cleaning liquid circulation system. The water pump sucks the cleaning liquid from the water inlet pipe, and after being distributed by the diverter box, it is sprayed on the surface of the elliptical tube by the atomizing nozzle, and cooperates with the cleaning brush to complete the cleaning work. The cleaned sewage is discharged through the drain pipe. The flow and pressure of the cleaning liquid can be controlled by the control valve. Through such a design, the heat exchanger can not only effectively clean the dust on the surface of the elliptical tube and improve the heat exchange efficiency, but also reduce the tediousness and inconvenience of manual cleaning through the automated cleaning system, thereby achieving the purpose of energy saving and emission reduction.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
