This heat exchanger fin belt cleaning device installs on the indoor side air outlet of heat exchanger, and the heat exchanger setting has seted up a big square hole in outdoor one side promptly on the wall body, just can hold the air outlet of heat exchanger. The heat exchanger fin cleaning device is equivalent to a 2-freedom-degree plane displacement platform which is provided with a movable space on an air outlet and can cover the whole air outlet surface, and a component with an air injection sharp nozzle and a water outlet head is arranged on the platform. The air injection sharp nozzle is connected with factory compressed air, whether the air is exhausted or not is controlled by a first electromagnetic valve, and the electromagnetic valve is controlled by a PLC. The water outlet head is connected to an outdoor small water tank through a hose, the small water tank is controlled by a second electromagnetic valve to discharge water or not through supply of domestic water in a plant area, a water level sensor is respectively arranged at the high water level and the low water level of the water tank, a switching value signal of the water level sensor is sent to the PLC, and the PLC controls the second electromagnetic valve to feed water to the small water tank according to the water level signal. The specific logic is as follows: when the low water level signal is triggered, the PLC sends a water adding command, and when the high water level signal arrives, the PLC sends a water closing command, so that the small water tank is ensured to have water all the time.
When the water cooling device needs to be cleaned, the first electromagnetic valve is opened, the air injection sharp nozzle sprays high-pressure air, meanwhile, water in the small water tank is quickly sucked out by the water outlet head due to local high negative pressure generated by airflow of the high-pressure air and is subjected to water dripping or even atomization under high-speed airflow, so that high-speed airflow with small water droplets and water mist is obtained, dust deposition of the fins can be stripped, the water droplets and the water mist can be quickly wetted, and finally, the water flows to the water collecting tank at the bottom of the water cooling device cabinet along the fins and is discharged from a water outlet arranged on the side face of the water collecting tank. Because the water is small water drops and water mist when being sprayed out, the water can not splash everywhere when contacting the fins.
Why does not directly supply water spraying with domestic water in this scheme, this is because the domestic water pipe is pressed the area, and spun water also presses the area, produces the water column easily and strikes and take place the bounce-back sputter behind the fin, can threaten high-voltage inverter safety. Meanwhile, once the valve is out of control or the joint leaks water and is sprayed, the high-voltage transformer is threatened, so that pressurized water cannot be used, and a water source cannot be indoors. In this scheme in case stop to wash (promptly stop gas), the residual water in the water pipe will flow back to outdoor little water tank under the action of gravity, and the water storage is whole outdoor, and the water pipe is pressureless, and this just stops can not be because of having increased this belt cleaning device because the insulating damage's that water produced risk.
The heat exchanger fin cleaning device overcomes the defects of the traditional method, so that the fin cleaning becomes automatic, safe and online, and the frequency conversion and air-water cooling system does not need to be stopped, thereby being safe and convenient.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
