Wherein, the cabinet 2 and the water tank 6 are integrally structured, and the water tank 6 is located at the rear of the cabinet 2 . The top of the water tank 6 is processed with a water tank mouth 12 for water injection; a plurality of suction cups 13 are evenly distributed on the rear side wall of the cabinet 2; The air outlet 3 is located at the upper part of the side wall of the chassis 2, the heat pipe 4 is fixed at the air outlet 3, and the centrifugal fan impeller hub is fixedly connected with the output shaft 11 of the motor. The distance between the inner wall of the cabinet 2 and the tip of the centrifugal fan blade 10 is 3 to 5 millimeters, which is used to increase the boosting ratio. The control panel 5 is installed below the air outlet 3, and the control panel 5 is respectively equipped with a fan switch 7, a high speed button 8, and a low speed button 9, and the control panel 5 controls the motor to drive the centrifugal fan blade 10 to rotate.

In this embodiment, the heat pipe 4 is cylindrical, and the inside of the heat pipe 4 is a spiral cavity. The heat pipe 4 is fixed horizontally and axially on the inner wall of the chassis 2, and is connected to the water pipe and the water pump in the water tank. The water pipe is connected to the multi-stage heat pipe. 4 are connected in parallel to form a circulation channel; multiple heat-conducting pipes 4 are arranged in a right-angled triangle at equal intervals from the air outlet 3 to the inside of the chassis 2, and the temperature is fully cooled in multiple stages. The heat conduction pipes 4 are fixed at the air outlet at equal intervals, and are flush with the end faces of the air outlet 3; the heat conduction pipes 4 are made of copper pipes.

In this embodiment, the shell of the water tank 6 adopts a double-layer structure, the outer layer is sound-insulating material, and the inner layer is heat-insulating material. The water pump is installed in the water tank 6 to provide water circulation power; the water tank is filled with cold water and ice crystals through the top water tank port 12. The fan is installed on the wall by the magnetic suction of the suction cup 13.

The working process of this embodiment

When using the fan, after pressing the fan switch 7 on the control panel 5, the control panel emits an electrical signal, and after the motor receives the signal, the motor drives the motor output shaft 11 to drive the centrifugal fan blade 10 to rotate, and the airflow flows from the air inlet along the The axial direction enters into the fan case 2, and is swept out tangentially along the air outlet 3 of the case; the dust-proof gauze 1 is installed at the air inlet to filter dust and protect. Simultaneously, the water pump inside the water tank 6 starts to work, so that the cold water in the water tank 6 enters the water pipe arranged on the inner wall of the cabinet. Cool down when passing through the heat pipe 4, and the heat pipe 4 cools down the outlet airflow and blows out cold air. Press the high speed button 8 on the control panel 5 or the low speed button 9 to increase or decrease the speed of the fan, if you press the fan switch 7 on the control panel 5 again, the fan 10 stops working. The fan is installed on the wall by the suction cup 13 on the back of the chassis.

In this embodiment, the multi-stage water circulation cooling pipes are arranged in a right-angled triangle, and the pipes are fully cooled by cold water, and then the multi-stage pipes are used to cool the air flow, so that the fan blows out cold air; secondly, the heat pipes are arranged from outside to inside along the outlet. The decreasing right-angle triangle arrangement makes the airflow with the fastest velocity in the outermost ring pass through more heat transfer tubes, while the airflow with a lower flow rate than the inner ring passes through fewer heat transfer tubes, so the cooling effect is stable.

The shell of the water tank adopts a double-layer structure, and the water pump is installed inside the water tank to provide water circulation power so that the water enters the pipeline, flows through the cooling pipe and returns to the water tank. Due to the small height difference between the water tank and the pipeline, the power requirement of the water pump is small, and the noise is reduced; the water tank is made of sound insulation and thermal insulation materials, which can reduce the noise of the water pump and maintain the temperature of the cold water. Ice crystals are placed in the water tank and contact with water to cool down the water.
