Heat exchanger cleaning device and outdoor unit of air conditioner

Abstract

The invention provides a heat exchanger cleaning device and an outdoor unit of an air conditioner. The heat exchanger cleaning device is used for cleaning a heat exchanger in an outdoor unit of an airconditioner, and comprises a steam generation device and a spray washing device with an annular tubular structure. The steam generation device generates high-pressure steam; multiple spraying holes are formed in the surface, towards the heat exchanger, of at least one section of tube section of the spray washing device with the annular tubular structure; and the spray washing device communicateswith a steam outlet of the steam generation device through a pipeline for spray washing of the heat exchanger by using the high-pressure steam sprayed from the multiple spraying holes. The heat exchanger cleaning device can spray the high-pressure steam to the surface and gaps of the heat exchanger through the spraying holes; the high-pressure steam can penetrate through the gaps of fins of the heat exchanger to uniformly attach on the surfaces of the fins and to dissolve dust on the surface to generate water drops; and the dust and dirt on the surfaces of the fins are stripped by dint of gravity of the water drops to achieve the cleaning purpose. The heat exchanger cleaning device needs no manual work, and meanwhile, is high in cleaning efficiency.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to a heat exchanger cleaning device and an air conditioner outdoor unit. Background technique [0002] During the long-term use of commercial air conditioners, a large amount of dust will adhere to the heat dissipation fins of the evaporator in the external unit, which needs to be cleaned regularly. Otherwise, the heat dissipation effect of the evaporator will be greatly reduced, thereby affecting the cooling performance of the air conditioner. [0003] In the prior art, the cleaning method for commercial air-conditioning outdoor units is generally manual direct flushing with water pipes. This cleaning method not only requires manual labor, but also needs to disassemble the shell of the external machine first, otherwise, the cleaning effect through the shell is poor, so it is time-consuming and laborious. Simultaneously, this cleaning method also can waste a large amount of water r...

AI Technical Summary

Problems solved by technology

This cleaning method not only requires manual labor, but also needs to disassemble the shell of the external machine first, otherwise, the cleaning effect will be poor through the shell, so it is time-consuming and laborious.

At the same time, this cleaning method will waste a lot of water resources

In addition, if the air conditioner is far away from the water source, the cleaning operation is very inconvenient

Moreover, this cleaning method has a poor cleaning effect and cannot remove the dirt in the air conditioner evaporator well.
